We study the Horizon Wave Function (HWF) description of a generalized
uncertainty principle (GUP) black hole in the presence of two natural cutoffs
as a minimal length and a maximal momentum. This is motivated by a metric which
allows the existence of sub-Planckian black holes, where the black hole mass
$m$ is replaced by
$M=m\Big(1+\frac{\beta^{2}}{2}\frac{M_{pl}^{2}}{m^{2}}-\beta\frac{M_{pl}}{m}\Big)$.
Considering a wave-packet with a Gaussian profile, we evaluate the HWF and the
probability that the source might be a (quantum) black hole. By decreasing the
free parameter the general form of probability distribution,
${\mathcal{P}}_{BH}$, is preserved , but this resulted in reducing the
probability for the particle to be a black hole accordingly. The probability
for the particle to be a black hole grows when the mass is increasing slowly
for larger positive $\beta$, and for a minimum mass value it reaches to $0$. In
effect, for larger $\beta$ the magnitude of $M$ and $r_{H}$ increases, matching
with our intuition that either the particle ought to be more localized or more
massive to be a black hole. The scenario undergoes a change for some values of
$\beta$ significantly, where there is a minimum in ${\mathcal{P}}_{BH}$ , so
this expresses that every particle can have some probability of decaying to a
black hole. In addition, for sufficiently large $\beta$ we find that every
particle could be fundamentally a quantum black hole.

In this paper, we introduce DA$^2$, the first large-scale dual-arm
dexterity-aware dataset for the generation of optimal bimanual grasping pairs
for arbitrary large objects. The dataset contains about 9M pairs of
parallel-jaw grasps, generated from more than 6000 objects and each labeled
with various grasp dexterity measures. In addition, we propose an end-to-end
dual-arm grasp evaluation model trained on the rendered scenes from this
dataset. We utilize the evaluation model as our baseline to show the value of
this novel and nontrivial dataset by both online analysis and real robot
experiments. All data and related code will be open-sourced at

Chiral molecules are characterized by a specific optical rotation angle. An
experimental method was presented to dissect the temperature dependence of the
optical rotation angle with the molecular chirality of D-alanine, L-alanine and
DL-alanine crystals. Salam hypothesis predicted that quantum mechanical
cooperative and condensation phenomena may give rise to a second order phase
transition below a critical temperature linking the transformation of D-amino
acids to L-amino acids due to parity-violating energy difference. The
temperature- dependent measurement of the optical rotation angle of D-, L- and
DL-alanine crystals provided the direct evidence of the phase transition, but
denied the configuration change from D-alanine to L-alanine. New views on Salam
hypothesis are presented to demonstrate its importance in the application of
low temperature enantiomeric separation and the origin of biochirality.

To Relay or Not to Relay: Learning Device-to-Device Relaying Strategies
in Cellular Networks

We consider a cellular network where mobile transceiver devices that are
owned by self-interested users are incentivized to cooperate with each other
using tokens, which they exchange electronically to "buy" and "sell" downlink
relay services, thereby increasing the network's capacity compared to a network
that only supports base station-to-device (B2D) communications. We investigate
how an individual device in the network can learn its optimal cooperation
policy online, which it uses to decide whether or not to provide downlink relay
services for other devices in exchange for tokens. We propose a supervised
learning algorithm that devices can deploy to learn their optimal cooperation
strategies online given their experienced network environment. We then
systematically evaluate the learning algorithm in various deployment scenarios.
Our simulation results suggest that devices have the greatest incentive to
cooperate when the network contains (i) many devices with high energy budgets
for relaying, (ii) many highly mobile users (e.g., users in motor vehicles),
and (iii) neither too few nor too many tokens. Additionally, within the token
system, self-interested devices can effectively learn to cooperate online, and
achieve over 20% higher throughput on average than with B2D communications
alone, all while selfishly maximizing their own utilities.

We list and analyze H I absorption lines at redshifts 2 < z < 4 with column
density (12 < log(N_HI) < 19) in 40 high-resolutional (FWHM = 8.0 km/s) quasar
spectra obtained with the Keck+HIRES. We de-blend and fit all H I lines within
1,000 km/s of 86 strong H I lines whose column densities are log(N_HI/[cm^-2])
> 15. Unlike most prior studies, we use not only Lya but also all visible
higher Lyman series lines to improve the fitting accuracy. This reveals
components near to higher column density systems that can not be seen in Lya.
We list the Voigt profile fits to the 1339 H I components that we found. We
examined physical properties of H I lines after separating them into several
sub-samples according to their velocity separation from the quasars, their
redshift, column density and the S/N ratio of the spectrum. We found two
interesting trends for lines with 12 < log(N_HI) < 15 which are within 200-1000
km/s of systems with log(N_HI) > 15. First, their column density distribution
becomes steeper, meaning relatively fewer high column density lines, at z <
2.9. Second, their column density distribution also becomes steeper and their
line width becomes broader by about 2-3 km/s when they are within 5,000 km/s of
their quasar.

We present the results of H-alpha monitoring of the BL Lac object OJ 287 with
the VLT during seven epochs in 2005-08. We were able to detect five previously
undetected narrow emission lines, 6548,6583[NII], 6563H-alpha$ and
6716,6731[SII] during at least one of the epochs and a broad H-alpha feature
during two epochs. The broad H-alpha luminosity was a factor ~10 lower in
2005-08 than in 1984 when the line was previously detected and a factor ~10
lower than what is observed in quasars and Seyfert galaxies at the same
redshift. The data are consistent with no change in the position or luminosity
of the H-alpha line in 2005-08. The width of the H-alpha line was 4200 +- 500
km/s, consistent with the width in 1984.

An ever increasing number of battlefield devices that are capable of
collecting, processing, storing, and communicating information are rapidly
becoming interconnected. The staggering number of connected devices on the
battlefield greatly increases the possibility that an adversary could find ways
to exploit hardware or software vulnerabilities, degrading or denying
Warfighters the assured and secure use of those devices. Autonomous software
agents will become necessities to manage, defend, and react to cyber threats in
the future battlespace. The number of connected devices increases
disproportionately to the number of cyber experts that could be available
within an operational environment. In this paper, an autonomous agent
capability and a scenario of how it could operate are proposed. The goal of
developing such capability is to increase the security posture of the Internet
of Battlefield Things and meet the challenges of an increasingly complex
battlefield. This paper describes an illustrative scenario in a notional use
case and discusses the challenges associated with such autonomous agents. We
conclude by offering ideas for potential research into developing autonomous
agents suitable for cyber defense in a battlefield environment.

In the d=3 gluon mass problem in pure-glue non-Abelian $SU(N)$ gauge theory
we pay particular attention to the observed (in Landau gauge) violation of
positivity for the spectral function of the gluon propagator. This causes a
large bulge in the propagator at small momentum. Mass is defined through
$m^{-2}=\Delta (p=0)$, where $\Delta(p)$ is the scalar function for the gluon
propagator in some chosen gauge, it is not a pole mass and is generally
gauge-dependent, except in the gauge-invariant Pinch Technique (PT). We
truncate the PT equations with a new method called the vertex paradigm that
automatically satisfies the QED-like Ward identity relating the 3-gluon PT
vertex function with the PT propagator. The mass is determined by a homogeneous
Bethe-Salpeter equation involving this vertex and propagator. This gap equation
also encapsulates the Bethe-Salpeter equation for the massless scalar
excitations, essentially Nambu-Goldstone fields, that necessarily accompany
gauge-invariant gluon mass. The problem is to find a good approximate value for
$m$ and at the same time explain the bulge, which by itself leads, in the gap
equation for the gluon mass, to excessively large values for the mass. Our
point is not to give a high-accuracy determination of $m$ but to clarify the
way in which the propagator bulge and a fairly accurate estimate of $m$ can
co-exist, and we use various approximations that illustrate the underlying
mechanisms. The most critical point is to satisfy the Ward identity. In the PT
we estimate a gauge-invariant dynamical gluon mass of $m \approx Ng^2/(2.48
\pi)$. We translate these results to the Landau gauge using a
background-quantum identity involving a dynamical quantity $\kappa$ such that
$m=\kappa m_L$, where $m_L^{-2}\equiv \Delta_L(p=0)$. Given our estimates for
$m,\kappa$ the relation is fortuitously well-satisfied for $SU(2)$ lattice
data.

Scale Dependence of Nucleon-Nucleon Potentials

The scale-dependence of the nucleon-nucleon interaction, which in recent
years has been extensively analysed within the context of chiral effective
field theory, is, in fact, inherent in any potential models constrained by a
fit to scattering data. A comparison between a purely phenomenological
potential and local interactions derived from chiral effective field theory
suggests that--thanks to the ability to describe nucleon-nucleon scattering at
higher energies, as well as the deuteron momentum distribution extracted from
electro-disintegration data--phenomenological potentials are best suited for
the description of nuclear dynamics at the scale relevant to neutron star
matter.

In this manuscript, I will report the details of our recent work on the
vector meson-baryon (VB) interaction, which we studied with the motivation of
finding dynamical generation of resonances in the corresponding systems. We
started our study by building a formalism based on the hidden local symmetry
and calculating the leading order contributions to the scattering equations by
summing the diagrams with: (a) a vector meson exchange in the t-channel (b) an
octet baryon exchange in the s-, u-channels and (c) a contact interaction
arising from the part of the vector meson-baryon Lagrangian which is related to
the anomalous magnetic moment of the baryons. We find the contribution from all
these sources, except the s-channel, to be important. The amplitudes obtained
by solving the coupled channel Bethe-Salpeter equations for the systems with
total strangeness zero, show generation of one isospin 3/2, spin 1/2 resonance
and three isospin 1/2 resonances: two with spin 3/2 and one with spin 1/2. We
identify these resonances with $\Delta$ (1900) $S_{31}$, $N^*$(2080) $D_{13}$,
$N^*$(1700) $D_{13}$, and $N^*$(2090) $S_{11}$, respectively.
We have further extended our study by including pseudoscalar meson-baryon
(PB) as the coupled channels of VB systems. For this, we obtain the PB
$\rightarrow$ VB amplitudes by using the Kroll-Ruddermann term where,
considering the vector meson dominance phenomena, the photon is replaced by a
vector meson. The calculations done within this formalism reveal a very strong
coupling of the VB channels to the low-lying resonances like $\Lambda$(1405)
and $\Lambda$(1670), which can have important implications on certain reactions
producing them. In addition to this, we find that the effect of coupling the
higher mass states to the lighter channels is not restricted to increasing the
width of those states, it can be far more strong.

Data-driven deep learning based code designs, including low-complexity neural
decoders for existing codes, or end-to-end trainable auto-encoders have
exhibited impressive results, particularly in scenarios for which we do not
have high-performing structured code designs. However, the vast majority of
existing data-driven solutions for channel coding focus on a point-to-point
scenario. In this work, we consider a multiple access channel (MAC) with
feedback and try to understand whether deep learning-based designs are capable
of enabling coordination and cooperation among the encoders as well as allowing
error correction. Simulation results show that the proposed multi-access block
attention feedback (MBAF) code improves the upper bound of the achievable rate
of MAC without feedback in finite block length regime.

We study biorthogonal sequences with special properties, such as weak or

theorem. This result is applied to embed analytic disks in the fiber over 0 of
the spectrum of H^infinity (B), the algebra of bounded analytic functions on
the unit ball B of an arbitrary infinite dimensional Banach space. Various
other embedding theorems are obtained. For instance, if the Banach space is
superreflexive, then the unit ball of a Hilbert space of uncountable dimension
can be embedded analytically in the fiber over 0 via an embedding which is
uniformly bicontinuous with respect to the Gleason metric.

In this paper we derive analytical expressions for the central and side
quantizers which, under high-resolutions assumptions, minimize the expected
distortion of a symmetric multiple-description lattice vector quantization
(MD-LVQ) system subject to entropy constraints on the side descriptions for
given packet-loss probabilities.
We consider a special case of the general n-channel symmetric
multiple-description problem where only a single parameter controls the
redundancy tradeoffs between the central and the side distortions. Previous
work on two-channel MD-LVQ showed that the distortions of the side quantizers
can be expressed through the normalized second moment of a sphere. We show here
that this is also the case for three-channel MD-LVQ. Furthermore, we conjecture
that this is true for the general n-channel MD-LVQ.
For given source, target rate and packet-loss probabilities we find the
optimal number of descriptions and construct the MD-LVQ system that minimizes
the expected distortion. We verify theoretical expressions by numerical
simulations and show in a practical setup that significant performance
improvements can be achieved over state-of-the-art two-channel MD-LVQ by using

We have studied the phi(1020)a0(980) S-wave scattering at threshold energies
employing chiral Lagrangians coupled to vector mesons by minimal coupling. The
interaction is described without new free parameters by considering the scalar
isovector a0(980) resonance as dynamically generated in coupled channels, and
demanding that the recently measured e+ e- -> phi(1020) f0(980) cross section
is reproduced. For some realistic choices of the parameters, the presence of a
dynamically generated isovector companion of the Y(2175) is revealed. We have
also investigated the corrections to the e+ e- -> phi(1020) pi0 eta reaction
cross section that arise from phi(1020)a0(980) re-scattering in the final
state. They are typically large and modify substantially the cross section. For
a suitable choice of parameters, the presence of the resonance would manifest
itself as a clear peak at sqrt{s}~2.03 GeV in e+ e- -> phi(1020) pi0 eta.

We report the discovery of a new ultra-faint stellar system found near the
Magellanic Clouds in the DECam Local Volume Exploration (DELVE) Survey. This
new system, DELVE J0155$-$6815 (DELVE 2), is located at a heliocentric distance
of $D_{\odot} = 71 \pm 4\text{ kpc}$, which places it at a 3D physical
separation of 12 kpc from the center of Small Magellanic Cloud (SMC) and 28 kpc
from the center of the Large Magellanic Cloud (LMC). DELVE 2 is identified as a
resolved overdensity of old ($\tau > 13.3\text{ Gyr}$) and metal-poor (${\rm
[Fe/H]} = -2.0_{-0.5}^{+0.2}$ dex) stars with a projected half-light radius of
$r_{1/2} = 21^{+4}_{-3}\text{ pc}$ and an absolute magnitude of $M_V =
-2.1^{+0.4}_{-0.5}\text{ mag}$. The size and luminosity of DELVE 2 are
consistent with both the population of recently discovered ultra-faint globular
clusters and the smallest ultra-faint dwarf galaxies. However, its age and
metallicity would place it among the oldest and most metal-poor globular
clusters in the Magellanic system. DELVE 2 is detected in Gaia DR2 with a clear
proper motion signal, with multiple blue horizontal branch stars near the
centroid of the system with proper motions consistent with the systemic mean.
We measure the system proper motion to be $(\mu_{\alpha} \cos \delta,
\mu_{\delta})= (1.02_{-0.25}^{+0.24}, -0.85_{-0.19}^{+0.18})$ mas yr$^{-1}$. We
compare the spatial position and proper motion of DELVE 2 with simulations of
the accreted satellite population of the LMC and find that it is very likely to
be associated with the LMC.

We study positive Toeplitz operators on the Bergman spaces having the fast
decreasing weight functions in a certain class. We give the characterizations
for the boundedness and compactness of Toeplitz operators in terms of their
Berezin transforms and averaging functions. In particular, we show the
equivalent conditions in order that Toeplitz operators on $A^2(\omega)$ belong
to the Schatten class $S_p$, $0<p<\infty$.

Readability is on the cusp of a revolution. Fixed text is becoming fluid as a
proliferation of digital reading devices rewrite what a document can do. As
past constraints make way for more flexible opportunities, there is great need
to understand how reading formats can be tuned to the situation and the
individual. We aim to provide a firm foundation for readability research, a
comprehensive framework for modern, multi-disciplinary readability research.
Readability refers to aspects of visual information design which impact
information flow from the page to the reader. Readability can be enhanced by
changes to the set of typographical characteristics of a text. These aspects
can be modified on-demand, instantly improving the ease with which a reader can
process and derive meaning from text. We call on a multi-disciplinary research
community to take up these challenges to elevate reading outcomes and provide
the tools to do so effectively.

In this paper, we consider the finite time blow up of solutions for the
following two kinds of nonlinear wave equations on de Sitter spacetime
\begin{eqnarray*} &&\square_g=F(u),\\ &&\square_g=F(\partial_tu,\nabla u).
\end{eqnarray*} This proof is based on a new blow up criterion, which
generalize the blow up criterion in Sideris \cite{Sider}. Furthermore, we give
the lifespan estimate of solutions for the problems.

With transition towards 5G, mobile cellular networks are evolving into a
powerful platform for ubiquitous large-scale information acquisition,
communication, storage and processing. 5G will provide suitable services for
mission-critical and real-time applications such as the ones envisioned in
future Smart Grids. In this work, we show how emerging 5G mobile cellular
network, with its evolution of Machine-Type Communications and the concept of
Mobile Edge Computing, provides an adequate environment for distributed
monitoring and control tasks in Smart Grids. In particular, we present in
detail how Smart Grids could benefit from advanced distributed State Estimation
methods placed within 5G environment. We present an overview of emerging
distributed State Estimation solutions, focusing on those based on distributed
optimization and probabilistic graphical models, and investigate their
integration as part of the future 5G Smart Grid services.

The cross section for resonant ion-pair formation in the collision of
low-energy electrons with HF^+ is calculated by the solution of the
time-dependent Schrodinger equation with multiple coupled states using a wave
packet method. A diabatization procedure is proposed to obtain the electronic
couplings between quasidiabatic potentials of ^1Sigma^+ symmetry for HF. By
including these couplings between the neutral states, the cross section for
ion-pair formation increases with about two orders of magnitude compared with
the cross section for direct dissociation. Qualitative agreement with the
measured cross section is obtained. The oscillations in the calculated cross
section are analyzed. The cross section for ion-pair formation in electron
recombination with DF^+ is calculated to determine the effect of isotopic
substitution.

Calipso: Physics-based Image and Video Editing through CAD Model Proxies

We present Calipso, an interactive method for editing images and videos in a
physically-coherent manner. Our main idea is to realize physics-based
manipulations by running a full physics simulation on proxy geometries given by
non-rigidly aligned CAD models. Running these simulations allows us to apply
new, unseen forces to move or deform selected objects, change physical
parameters such as mass or elasticity, or even add entire new objects that
interact with the rest of the underlying scene. In Calipso, the user makes
edits directly in 3D; these edits are processed by the simulation and then
transfered to the target 2D content using shape-to-image correspondences in a
photo-realistic rendering process. To align the CAD models, we introduce an
efficient CAD-to-image alignment procedure that jointly minimizes for rigid and
non-rigid alignment while preserving the high-level structure of the input
shape. Moreover, the user can choose to exploit image flow to estimate scene
motion, producing coherent physical behavior with ambient dynamics. We
demonstrate Calipso's physics-based editing on a wide range of examples
producing myriad physical behavior while preserving geometric and visual
consistency.

We present a search for periodic gravitational waves from the neutron star in
the supernova remnant Cassiopeia A. The search coherently analyzes data in a
12-day interval taken from the fifth science run of the Laser Interferometer
Gravitational-Wave Observatory. It searches gravitational wave frequencies from
100 to 300 Hz, and covers a wide range of first and second frequency
derivatives appropriate for the age of the remnant and for different spin-down
mechanisms. No gravitational wave signal was detected. Within the range of
search frequencies, we set 95% confidence upper limits of 0.7--1.2e-24 on the
intrinsic gravitational wave strain, 0.4--4e-4 on the equatorial ellipticity of
the neutron star, and 0.005--0.14 on the amplitude of r-mode oscillations of
the neutron star. These direct upper limits beat indirect limits derived from
energy conservation and enter the range of theoretical predictions involving
crystalline exotic matter or runaway r-modes. This is the first gravitational
wave search to present upper limits on r-modes.

The realization of complex classification tasks requires training of deep
learning (DL) architectures consisting of tens or even hundreds of
convolutional and fully connected hidden layers, which is far from the reality
of the human brain. According to the DL rationale, the first convolutional
layer reveals localized patterns in the input and large-scale patterns in the
following layers, until it reliably characterizes a class of inputs. Here, we
demonstrate that with a fixed ratio between the depths of the first and second
convolutional layers, the error rates of the generalized shallow LeNet
architecture, consisting of only five layers, decay as a power law with the
number of filters in the first convolutional layer. The extrapolation of this
power law indicates that the generalized LeNet can achieve small error rates
that were previously obtained for the CIFAR-10 database using DL architectures.
A power law with a similar exponent also characterizes the generalized VGG-16
architecture. However, this results in a significantly increased number of
operations required to achieve a given error rate with respect to LeNet. This
power law phenomenon governs various generalized LeNet and VGG-16
architectures, hinting at its universal behavior and suggesting a quantitative
hierarchical time-space complexity among machine learning architectures.
Additionally, the conservation law along the convolutional layers, which is the
square-root of their size times their depth, is found to asymptotically
minimize error rates. The efficient shallow learning that is demonstrated in
this study calls for further quantitative examination using various databases
and architectures and its accelerated implementation using future dedicated
hardware developments.

Life history and mating systems select for male biased parasitism

Males are often the "sicker" sex with male biased parasitism found in a
taxonomically diverse range of species. There is considerable interest in the
processes that could underlie the evolution of sex-biased parasitism. Mating
system differences along with differences in lifespan may play a key role. We
examine whether these factors are likely to lead to male-biased parasitism
through natural selection taking into account the critical role that ecological
feedbacks play in the evolution of defence. We use a host-parasite model with
two-sexes and the techniques of adaptive dynamics to investigate how mating
system and sexual differences in competitive ability and longevity can select
for a bias in the rates of parasitism. Male-biased parasitism is selected for
when males have a shorter average lifespan or when males are subject to greater
competition for resources. Male-biased parasitism evolves as a consequence of
sexual differences in life history that produce a greater proportion of
susceptible females than males and therefore reduce the cost of avoiding
parasitism in males. Different mating systems such as monogamy, polygamy or
polyandry did not produce a bias in parasitism through these ecological
feedbacks but may accentuate an existing bias.

Scale invariance in cosmology and physics

The fundamental laws of physics are required to be invariant under local
spatial scale change. In 3-dimensional space, this leads to a variation in
Planck constant \hbar and speed of light c. They vary as \hbar ~ a^(1/2) and c
~ a^(-1/2), a is the local scale. A direct consequence is that the expanding
universe progressively alters the values of c which in turn affects the
evolution of the universe itself. Friedmann eqns violate scale invariance and
neglect to account for the scale dependency of c. We build a cosmological model
which is fully consistent with scale invariance and respects Lorentz
invariance. This model leads to a universe different from the ones depicted in
Friedmann model. We apply our model to resolve a series of observational and
theoretical difficulties in modern cosmology: "runaway density parameter"
problem, budgetary shortfall, horizon problem, eg. Our model does not resort to
inflation hypothesis. We derive a modification to the Hubble law and Hubble
constant, and a new brightness-redshift relationship for Type Ia supernovae:
(a) Hubble constant has been inadvertently overestimated by a factor of 9/5; so
has the critical density by (9/5)^2; (b) Our new photometric distance-redshift
relationship d_L=2c/(3H0)*(1+z)^(5/6)\ln(1+z) with one parameter H0=37 fits to
the high-$z$ objects as equally well as the traditional relationship does with
three parameters H0=70.5, OmegaM=0.27, OmegaL=0.73. We draw two conclusions:
(i) With H0=37, the critical density is only 0.28 time the value previously
thought; dark energy is absent. (ii) H0=37 restores the age estimate to 17.6 Gy
(via t_0=2/(3H0)). They also raise the possibility that the universe expansion
is not accelerating, but rather a result of c progressively adapting to new
spatial scale as the universe expands. Finally, we discuss an array of
implications of scale invariance in the larger context of physics.

Electronic and magnetic excitations in the "half-stuffed" Cu--O planes

We use resonant inelastic x-ray scattering (RIXS) at the Cu L$_3$ edge to
measure the charge and spin excitations in the "half-stuffed" Cu--O planes of
the cuprate antiferromagnet Ba$_2$Cu$_3$O$_4$Cl$_2$. The RIXS line shape
reveals distinct contributions to the $dd$ excitations from the two
structurally inequivalent Cu sites, which have different out-of-plane
coordinations. The low-energy response exhibits magnetic excitations. We find a
spin-wave branch whose dispersion follows the symmetry of a CuO$_2$ sublattice,
similar to the case of the "fully-stuffed" planes of tetragonal CuO (T-CuO).
Its bandwidth is closer to that of a typical cuprate material, such as
Sr$_2$CuO$_2$Cl$_2$, than it is to that of T-CuO. We interpret this result as
arising from the absence of the effective four-spin inter-sublattice
interactions that act to reduce the bandwidth in T-CuO.

We study cosmological perturbations in mimetic matter scenario with a general
higher derivative function. We calculate the quadratic action and show that
both the kinetic term and the gradient term have the wrong sings. We perform
the analysis in both comoving and Newtonian gauges and confirm that the
Hamiltonians and the associated instabilities are consistent with each other in
both gauges. The existence of instabilities is independent of the specific form
of higher derivative function which generates gradients for mimetic field
perturbations. It is verified that the ghost instability in mimetic
perturbations is not associated with the higher derivative instabilities such
as the Ostrogradsky ghost.

Convex Geometry and Duality of Over-parameterized Neural Networks

We develop a convex analytic approach to analyze finite width two-layer ReLU
networks. We first prove that an optimal solution to the regularized training
problem can be characterized as extreme points of a convex set, where simple
solutions are encouraged via its convex geometrical properties. We then
leverage this characterization to show that an optimal set of parameters yield
linear spline interpolation for regression problems involving one dimensional
or rank-one data. We also characterize the classification decision regions in
terms of a kernel matrix and minimum $\ell_1$-norm solutions. This is in
contrast to Neural Tangent Kernel which is unable to explain predictions of
finite width networks. Our convex geometric characterization also provides
intuitive explanations of hidden neurons as auto-encoders. In higher
dimensions, we show that the training problem can be cast as a finite
dimensional convex problem with infinitely many constraints. Then, we apply
certain convex relaxations and introduce a cutting-plane algorithm to globally
optimize the network. We further analyze the exactness of the relaxations to
provide conditions for the convergence to a global optimum. Our analysis also
shows that optimal network parameters can be also characterized as
interpretable closed-form formulas in some practically relevant special cases.

Asymptotics for some polynomial patterns in the primes

We prove asymptotic formulae for sums of the form $$
\sum_{n\in\mathbb{Z}^d\cap K}\prod_{i=1}^tF_i(\psi_i(n)), $$ where $K$ is a
convex body, each $F_i$ is either the von Mangoldt function or the
representation function of a quadratic form, and $\Psi=(\psi_1,\ldots,\psi_t)$
is a system of linear forms of finite complexity. When all the functions $F_i$
are equal to the von Mangoldt function, we recover a result of Green and Tao,
while when they are all representation functions of quadratic forms, we recover
a result of Matthiesen. Our formulae imply asymptotics for some polynomial
patterns in the primes. Specifically, they describe the asymptotic behaviour of
the number of $k$-term arithmetic progressions of primes whose common
difference is a sum of two squares.
The article combines ingredients from the work of Green and Tao on linear
equations in primes and that of Matthiesen on linear correlations amongst
integers represented by a quadratic form. To make the von Mangoldt function
compatible with the representation function of a quadratic form, we provide a
new pseudorandom majorant for both -- an average of the known majorants for
each of the functions -- and prove that it has the required pseudorandomness
properties.

Double quantum dots (DQDs) hold great promise as building blocks for quantum
technology as they allow for two electronic states to coherently couple.
Defining QDs with materials rather than using electrostatic gating allows for
QDs with a hard-wall confinement potential and more robust charge and spin
states. An unresolved problem is how to individually address these quantum
dots, which is necessary for controlling quantum states. We here report the
fabrication of double quantum dot devices defined by the conduction band edge
offset at the interface of the wurtzite and zinc blende crystal phases of InAs
in nanowires. By using sacrifical epitaxial GaSb markers selectively forming on
one crystal phase, we are able to precisely align gate electrodes allowing us
to probe and control each QD independently. We hence observe textbook-like
charge stability diagrams, a discrete energy spectrum and electron numbers
consistent with theoretical estimates and investigate the tunability of the
devices, finding that changing the electron number can be used to tune the
tunnel barrier as expected by simple band diagram arguments.

In this paper, which is of programmatic rather than quantitative nature, we
aim to further delineate and sharpen the future potential of the LISA mission
in the area of fundamental physics. Given the very broad range of topics that
might be relevant to LISA, we present here a sample of what we view as
particularly promising directions, based in part on the current research
interests of the LISA scientific community in the area of fundamental physics.
We organize these directions through a "science-first" approach that allows us
to classify how LISA data can inform theoretical physics in a variety of areas.
For each of these theoretical physics classes, we identify the sources that are
currently expected to provide the principal contribution to our knowledge, and
the areas that need further development. The classification presented here
should not be thought of as cast in stone, but rather as a fluid framework that
is amenable to change with the flow of new insights in theoretical physics.

Beam Delivery Simulation (BDSIM) is a program that simulates the passage of
particles in a particle accelerator. It uses a suite of standard high energy
physics codes (Geant4, ROOT and CLHEP) to create a computational model of a
particle accelerator that combines accurate accelerator tracking routines with
all of the physics processes of particles in Geant4. This unique combination
permits radiation and detector background simulations in accelerators where
both accurate tracking of all particles is required over long range or over
many revolutions of a circular machine, as well as interaction with the
material of the accelerator.

Generalized Gelfand-Dikii equation and solitonic electric fields for

Schwinger pair creation in a purely time-dependent electric field can be
reduced to an effective quantum mechanical problem using a variety of
formalisms. Here we develop an approach based on the Gelfand-Dikii equation for
scalar QED, and extent it to spinor QED. We discuss some solvable special cases
from this point of view. It was previously shown how to use the well-known
solitonic solutions of the KdV equation to construct "solitonic" electric
fields that do not create scalar pairs with an arbitrary fixed momentum. We
show that this construction can be adapted to the fermionic case in two
inequivalent ways, both leading to the vanishing of the pair-creation rate at
certain values of the P\"oschl-Teller like index $p$ of the associated
Schr\"odinger equation. Thus for any given momentum we can construct electric
fields that create scalar particles but not spinor particles, and also the
other way round. Therefore, while often spin is even neglected in Schwinger
pair creation, in such cases it becomes decisive.

Classifying ecosystem disservices and comparing their effects with
ecosystem services in Beijing, China

To completely understand the effects of urban ecosystems, the effects of
ecosystem disservices should be considered along with the ecosystem services
and require more research attention. In this study, we tried to better
understand its formation through the use of cascade flowchart and
classification systems and compare their effects with ecosystem services. It is
vitally important to differentiate final and intermediate ecosystem disservices
for understanding the negative effects of the ecosystem on human well-being.
The proposed functional classification of EDS (i.e. provisioning, regulating
and cultural EDS) should also help better bridging EDS and ES studies. In
addition, we used Beijing as a case study area to value the EDS caused by urban
ecosystems and compare the findings with ES values. The results suggested that
although EDS caused great financial loss the potential economic gain from
ecosystem services still significantly outweigh the loss. Our study only sheds
light on valuating the net effects of urban ecosystems. In the future, we

We consider the exact rogue periodic wave (rogue wave on the periodic
background) and periodic wave solutions for the Chen-Lee-Liu equation via the
odd-th order Darboux transformation. Then, the multi-layer physics-informed
neural networks (PINNs) deep learning method is applied to research the
data-driven rogue periodic wave, breather wave, soliton wave and periodic wave
solutions of well-known Chen-Lee-Liu equation. Especially, the data-driven
rogue periodic wave is learned for the first time to solve the partial
differential equation. In addition, using image simulation, the relevant
dynamical behaviors and error analysis for there solutions are presented. The
numerical results indicate that the rogue periodic wave, breather wave, soliton
wave and periodic wave solutions for Chen-Lee-Liu equation can be generated
well by PINNs deep learning method.

Peripheral Authentication for Parked Vehicles over Wireless Radio
Communication

Peripheral authentication is an important aspect in the vehicle networks to
provide services to only authenticated peripherals and a security to internal
vehicle modules such as anti-lock braking system, power-train control module,
engine control unit, transmission control unit, and tire pressure monitoring.
In this paper a three-way handshake scheme is proposed for a vehicle to a
keyfob authentication. A keyfob is a key with a secure hardware that
communicates and authenticates the vehicle over the wireless channel.
Conventionally, a vehicle to keyfob authentication is realized through a
challenge-response verification protocol. An authentic coupling between the
vehicle identity and the keyfob avoids any illegal access to the vehicle.
However, these authentication messages can be relayed by an active adversary,
thereby, can amplify the actual distance between an authentic vehicle and a
keyfob. Eventually, an adversary can possibly gain access to the vehicle by
relaying wireless signals and without any effort to generate or decode the
secret credentials. Hence, the vehicle to keyfob authentication scheme must
contain an additional attribute verification such as physical movement of a
keyfob holder.
Our solution is a two-party and three-way handshake scheme with proactive and
reactive commitment verification. The proposed solution also uses a time
interval verification such that both vehicle and keyfob would yield a similar
locomotion pattern of a dynamic keyfob within a similar observational time
interval. Hence, the solution is different from the distance bounding protocols
that require multiple iterations for the round-trip delay measurement. The
proposed scheme is shown to be adaptable with the existing commitment scheme
such as Schnorr identification scheme and Pedersen commitment scheme.

We introduce the problem of weakly supervised Multi-Object Tracking and
Segmentation, i.e. joint weakly supervised instance segmentation and
multi-object tracking, in which we do not provide any kind of mask annotation.
To address it, we design a novel synergistic training strategy by taking
advantage of multi-task learning, i.e. classification and tracking tasks guide
the training of the unsupervised instance segmentation. For that purpose, we
extract weak foreground localization information, provided by Grad-CAM
heatmaps, to generate a partial ground truth to learn from. Additionally, RGB
image level information is employed to refine the mask prediction at the edges
of the objects. We evaluate our method on KITTI MOTS, the most representative
benchmark for this task, reducing the performance gap on the MOTSP metric
between the fully supervised and weakly supervised approach to just 12% and
12.7% for cars and pedestrians, respectively.

The quantum mechanics of $N$ slowly-moving BPS black holes in five dimensions
is considered. A divergent continuum of states describing arbitrarily closely
bound black holes with arbitrarily small excitation energies is found. A
superconformal structure appears at low energies and can be used to define an
index counting the weighted number of supersymmetric bound states. It is shown
that the index is determined from the dimensions of certain cohomology classes
on the symmetric product of $N$ copies of $R^4$. An explicit computation for
the case of N=2 with no angular momentum yields a finite nonzero result.

Second sound phenomenon and ballistic heat conduction, the two wave like
propagation modes of heat, are the two most prominent, experimentally observed
non-Fourier effects of heat conduction. In this paper we compare three related
theories by quantitatively analyzing the crucial NaF experiments of Jackson,
Walker and McNelly, where these effects were observed together. We conclude
that with the available information the best comparison and insight is provided
by non-equilibrium thermodynamics with internal variables. However, the
available data and information is not the best, and further, new experiments
are necessary.

In a quantum-mechanical system, particle-hole duality implies that instead of
studying particles, we can get equivalent information by studying the missing
particles, the so-called holes. Using this duality picture for rotating fermion
condensates the vortices appear as holes in the Fermi see. Here we predict that
the formation of vortices in quantum dots at high magnetic fields causes
oscillations in the energy spectrum which can be experimentally observed using
accurate tunnelling spectroscopy. We use the duality picture to show that these
oscillations are caused by the localisation of vortices in rings.

How Community Agreements Can Improve Workplace Culture in Physics

Equity, Diversity, and Inclusion (EDI) committees and Codes of Conduct (CoC)
have become common in laboratories and physics departments across the country.
However, very often these EDI committees and CoC are not equipped to provide
practical consequences for violations, and therefore are mostly performative in
nature. A considerable effort has been devoted by various groups within APS
units and beyond the APS in developing instead what are now called Community
Guidelines. Community Guidelines help implement the core principles in CoC, by
setting expectations for participation in in-person events and virtual
communication. When further accompanied by accountability and enforcement
processes, they develop into Community Agreements. This White Paper discusses
the elements necessary to create and implement an effective Community
Agreement, reviews examples of Community Agreements in physics, and argues that
physics collaborations, physics departments, and ultimately as many physics
organizations as possible, however large or small, should have a Community
Agreement in place. We advocate that Community Agreements should become part of
the bylaws of any entity that has bylaws.

We studied the problematic of uncertainties in the diffuse gamma radiation
apparent in stacking analysis of EGRET data at low Galactic latitudes.
Subsequently, we co-added maps of counts, exposure and diffuse background, and
residuals, in varying numbers for different sub-categories of putatively and
known source populations (like PSRs). Finally we tested for gamma-ray excess
emission in those maps and attempt to quantify the systematic biases in such
approach. Such kind of an analysis will help the classification processes of
sources and source populations in the GLAST era.

We consider the one-loop effective potential at zero and finite temperature
in field theories with anisotropic space-time scaling, with critical exponent
$z=2$, including both scalar and gauge fields. Depending on the relative
strength of the coupling constants for the gauge and scalar interactions, we
find that there is a symmetry breaking term induced at one-loop at zero
temperature and we find symmetry restoration through a first-order phase
transition at high temperature.

In this paper we investigate the behavior of the condition number of the
stiffness matrix resulting from the approximation of a 2D Poisson problem by
means of the Virtual Element Method. It turns out that ill-conditioning appears
when considering high-order methods or in presence of "bad-shaped" (for
instance nonuniformly star-shaped, with small edges...) sequences of polygons.
We show that in order to improve such condition number one can modify the
definition of the internal moments by choosing proper polynomial functions that
are not the standard monomials. We also give numerical evidence that, at least
for a 2D problem, standard choices for the stabilization give similar results
in terms of condition number.

A prerequisite to successfully alleviate pain in animals is to recognize it,
which is a great challenge in non-verbal species. Furthermore, prey animals
such as horses tend to hide their pain. In this study, we propose a deep
recurrent two-stream architecture for the task of distinguishing pain from
non-pain in videos of horses. Different models are evaluated on a unique
dataset showing horses under controlled trials with moderate pain induction,
which has been presented in earlier work. Sequential models are experimentally
compared to single-frame models, showing the importance of the temporal
dimension of the data, and are benchmarked against a veterinary expert
classification of the data. We additionally perform baseline comparisons with
generalized versions of state-of-the-art human pain recognition methods. While
equine pain detection in machine learning is a novel field, our results surpass
veterinary expert performance and outperform pain detection results reported
for other larger non-human species.

Joint detection of drivable areas and road anomalies is very important for
mobile robots. Recently, many semantic segmentation approaches based on
convolutional neural networks (CNNs) have been proposed for pixel-wise drivable
area and road anomaly detection. In addition, some benchmark datasets, such as
KITTI and Cityscapes, have been widely used. However, the existing benchmarks
are mostly designed for self-driving cars. There lacks a benchmark for ground
mobile robots, such as robotic wheelchairs. Therefore, in this paper, we first
build a drivable area and road anomaly detection benchmark for ground mobile
robots, evaluating the existing state-of-the-art single-modal and data-fusion
semantic segmentation CNNs using six modalities of visual features.
Furthermore, we propose a novel module, referred to as the dynamic fusion
module (DFM), which can be easily deployed in existing data-fusion networks to
fuse different types of visual features effectively and efficiently. The
experimental results show that the transformed disparity image is the most
informative visual feature and the proposed DFM-RTFNet outperforms the
state-of-the-arts. Additionally, our DFM-RTFNet achieves competitive
performance on the KITTI road benchmark. Our benchmark is publicly available at
https://sites.google.com/view/gmrb.

The main result here is that a simple separable C*-algebra is Z-stable (where
Z denotes the Jiang-Su algebra) if (i) it has finite nuclear dimension or (ii)
it is approximately subhomogeneous with slow dimension growth. This generalizes
the main results of [Toms, "K-theoretic rigidity and slow dimension growth";
Winter, "Nuclear dimension and Z-stability of pure C*-algebras"] to the
nonunital setting. As a consequence, finite nuclear dimension implies
Z-stability even in the case of a separable C*-algebra with finitely many
ideals. Algebraic simplicity is established as a fruitful weakening of being
simple and unital, and the proof of the main result makes heavy use of this
concept.

Kernelized Stein discrepancy (KSD) is a score-based discrepancy widely used
in goodness-of-fit tests. It can be applied even when the target distribution
has an unknown normalising factor, such as in Bayesian analysis. We show
theoretically and empirically that the KSD test can suffer from low power when
the target and the alternative distributions have the same well-separated modes
but differ in mixing proportions. We propose to perturb the observed sample via
Markov transition kernels, with respect to which the target distribution is
invariant. This allows us to then employ the KSD test on the perturbed sample.
We provide numerical evidence that with suitably chosen transition kernels the
proposed approach can lead to substantially higher power than the KSD test.

of $\mathbb{R}^n$. Such a sequence is called universal for a family of sets if
the successive symmetrals of any set in the family converge to a ball with
center at the origin. New universal sequences for the main symmetrizations, for
all valid dimensions $i$ of the subspaces, are found, by combining two groups
of results. The first, published separately, provides finite sets
${\mathcal{F}}$ of subspaces such that reflection symmetry (or rotational
symmetry) with respect to each subspace in ${\mathcal{F}}$ implies full
rotational symmetry. In the second, proved here, a theorem of Klain for Steiner
symmetrization is extended to Schwarz, Minkowski, Minkowski-Blaschke, and fiber
symmetrizations, showing that if a sequence of subspaces is drawn from a finite
set ${\mathcal{F}}$ of subspaces, the successive symmetrals of any compact
convex set converge to a compact convex set that is symmetric with respect to
any subspace in ${\mathcal{F}}$ appearing infinitely often in the sequence. It
is also proved that for Steiner, Schwarz, and Minkowski symmetrizations, a
sequence of $i$-dimensional subspaces is universal for the class of compact
sets if and only if it is universal for the class of compact convex sets, and
Klain's theorem is shown to hold for Schwarz symmetrization of compact sets.

A software package for modeling segmented High-Purity Segmented Germanium
detectors, AGATAGeFEM, is presented. The choices made for geometry
implementation and the calculations of the electric and weighting fields are
discussed. Models used for charge-carrier velocities are described. Numerical
integration of the charge-carrier transport equation is explained. Impact of
noise and crosstalk on the achieved position resolution in AGATA detectors are
investigated. The results suggest that crosstalk as seen in the AGATA detectors
is of minor importance for the position resolution. The sensitivity of the
pulse shapes to the parameters in the pulse-shape calculations is determined,
this as a function of position in the detectors. Finally, AGATAGeFEM has been
used to produce pulse-shape data bases for pulse-shape analyses of experimental
data. The results with the new data base indicate improvement with respect to
those with the standard AGATA data base.

Design and Validation of a Virtual Player for Studying Interpersonal
Coordination in the Mirror Game
| null | null | null | null |

|
The mirror game has been recently proposed as a simple, yet powerful paradigm
for studying interpersonal interactions. It has been suggested that a virtual
partner able to play the game with human subjects can be an effective tool to
affect the underlying neural processes needed to establish the necessary
connections between the players, and also to provide new clinical interventions
for the rehabilitation of patients suffering from social disorders. Inspired by
the motor processes of the central nervous system (CNS) and the musculoskeletal
system in the human body, in this paper we develop a novel interactive
cognitive architecture based on nonlinear control theory to drive a virtual
player (VP) to play the mirror game with a human player (HP) in different
configurations. Specifically, we consider two cases: the former where the VP
acts as leader and the latter where it acts as follower. The crucial problem is
to design a feedback control architecture capable of imitating and following or
leading a human player (HP) in a joint action task. Movement of the
end-effector of the VP is modeled by means of a feedback controlled
Haken-Kelso-Bunz (HKB) oscillator, which is coupled with the observed motion of
the HP measured in real time. To this aim, two types of control algorithms
(adaptive control and optimal control) are used and implemented on the HKB
model so that the VP can generate human-like motion while satisfying certain
kinematic constraints. A proof of convergence of the control algorithms is
presented in the paper together with an extensive numerical and experimental
validation of their effectiveness. A comparison with other existing designs is
also discussed, showing the flexibility and the advantages of our control-based
approach.

The interconnected wealth of nations: Shock propagation on global
trade-investment multiplex networks

The increasing integration of world economies, which organize in complex
multilayer networks of interactions, is one of the critical factors for the
global propagation of economic crises. We adopt the network science approach to
quantify shock propagation on the global trade-investment multiplex network. To
this aim, we propose a model that couples a Susceptible-Infected-Recovered
epidemic spreading dynamics, describing how economic distress propagates
between connected countries, with an internal contagion mechanism, describing
the spreading of such economic distress within a given country. At the local
level, we find that the interplay between trade and financial interactions
influences the vulnerabilities of countries to shocks. At the large scale, we
find a simple linear relation between the relative magnitude of a shock in a
country and its global impact on the whole economic system, albeit the strength
of internal contagion is country-dependent and the intercountry propagation
dynamics is non-linear. Interestingly, this systemic impact can be predicted on
the basis of intra-layer and inter-layer scale factors that we name network
multipliers, that are independent of the magnitude of the initial shock. Our
model sets-up a quantitative framework to stress-test the robustness of
individual countries and of the world economy to propagating crashes.

The electronic structure of ThPd$_2$Al$_3$, which is isostructural to the
heavy fermion superconductor UPd$_2$Al$_3$, was investigated by photoelectron
spectroscopy. The band structure and Fermi surfaces of ThPd$_2$Al$_3$ were
obtained by angle-resolved photoelectron spectroscopy (ARPES), and the results
were well-explained by the band-structure calculation based on the local
density approximation. The comparison between the ARPES spectra and the
band-structure calculation suggests that the Fermi surface of ThPd$_2$Al$_3$
mainly consists of the Al $3p$ and Th $6d$ states with a minor contribution
from the Pd $4d$ states. The comparison of the band structures between
ThPd$_2$Al$_3$ and UPd$_2$Al$_3$ argues that the U $5f$ states form Fermi
surfaces in UPd$_2$Al$_3$ through hybridization with the Al $3p$ state in the
Al layer, suggesting that the Fermi surface of UPd$_2$Al$_3$ has a strong
three-dimensional nature.

We compute the Rabinowitz Floer homology for a class of non-compact
hyperboloids $\Sigma\simeq S^{n+k-1}\times\mathbb{R}^{n-k}$. Using an embedding
of a compact sphere $\Sigma_0\simeq S^{2k-1}$ into the hypersurface $\Sigma$,
we construct a chain map from the Floer complex of $\Sigma$ to the Floer
complex of $\Sigma_0$. In contrast to the compact case, the Rabinowitz Floer
homology groups of $\Sigma$ are both non-zero and not equal to its singular
homology. As a consequence, we deduce that the Weinstein Conjecture holds for
any strongly tentacular deformation of such a hyperboloid.

Unbiased learning to rank (ULTR) aims to mitigate various biases existing in
user clicks, such as position bias, trust bias, presentation bias, and learn an
effective ranker. In this paper, we introduce our winning approach for the
"Unbiased Learning to Rank" task in WSDM Cup 2023. We find that the provided
data is severely biased so neural models trained directly with the top 10
results with click information are unsatisfactory. So we extract multiple
heuristic-based features for multi-fields of the results, adjust the click
labels, add true negatives, and re-weight the samples during model training.
Since the propensities learned by existing ULTR methods are not decreasing
w.r.t. positions, we also calibrate the propensities according to the click
ratios and ensemble the models trained in two different ways. Our method won
the 3rd prize with a DCG@10 score of 9.80, which is 1.1% worse than the 2nd and
25.3% higher than the 4th.

In granular media, the characterization of the behavior of solitary waves
around interfaces is of importance in order to look for more applications of
these systems. We study the behavior of solitary waves at both interfaces of a
symmetric granular container, a class of systems that has received recent
attention because it posses the feature of energy trapping. Hertzian contact is
assumed. We have found that the scattering process is elastic at one interface,
while at the other interface it is observed that the transmitted solitary wave
has stopped its movement during a time that gets longer when the ratio between
masses at the interfaces increases. The origin of this effect can be traced
back to the phenomenon of gaps opening, recently observed experimentally.

We have proposed a model to obtain the length of the day and month at any
geologic time. The day is found to increase by 0.002 sec/century since the
seventeenth century. The lengthening of the day is attributed entirely to the
increasing gravitational constant ($G$) with time that manifested its self in
tidal forces. The data obtained are consistent with those found from
Palaeontology. The length of the day 4500 million years ago was 6 hours and the
synodic month was 56.26 present epoch days.

The fourth generation can give the correct trend of S_{phi K^0}, S_{pi^0 K^0}
< sin2phi_1/beta, as indicated by data, and the effect, being largely leading
order, is robust against hadronic uncertainties. The effect on S_{eta' K^0},
however, is diluted away by hadronic effects, and S_{eta' K^0} \simeq
sin2phi_1/beta is expected. The near maximal arg[V^*_{t's}V_{t'b}] \lesssim
90^\circ that is needed could resolve the unequal direct CP violation seen in B
-> K^+ pi^- and K^+ pi^0 modes, and is consistent with b ->s l^+l^- and B_s

In local helioseismology numerical simulations of wave propagation are useful
to model the interaction of solar waves with perturbations to a background
solar model. However, the solution to the equations of motions include
convective modes that can swamp the waves we are interested in. For this
reason, we choose to first stabilise the background solar model against
convection by altering the vertical pressure gradient. Here we compare the
eigenmodes of our convectively stabilised model with a standard solar model
(Model S) and find a good agreement.

We discuss a weak constraint qualification for conic linear programs and its
applications for a few classes of cones. This constraint qualification is used
to give a solution to a problem proposed by Shapiro and Z\v{a}linescu and show
that if a closed convex cone is such that all its non-trivial faces are
polyhedral and all the non-trivial exposed faces of its dual are polyhedral,
then the duality gap is zero as long as the primal and dual problems are
feasible. Moreover, the common optimal value must be attained at least at one
of the sides. We also show an example of a cone that meets the requirements our
theorem but is such that previously known results cannot be used to prove its
good duality properties.

We present the development of a second generation digital readout system for
photon counting microwave kinetic inductance detector (MKID) arrays operating
in the optical and near-IR wavelength bands. Our system retains much of the
core signal processing architecture from the first generation system, but with
a significantly higher bandwidth, enabling readout of kilopixel MKID arrays.
Each set of readout boards is capable of reading out 1024 MKID pixels
multiplexed over 2 GHz of bandwidth; two such units can be placed in parallel
to read out a full 2048 pixel microwave feedline over a 4 -- 8 GHz band. As in
the first generation readout, our system is capable of identifying, analyzing,
and recording photon detection events in real time with a time resolution of
order a few microseconds. Here, we describe the hardware and firmware, and
present an analysis of the noise properties of the system. We also present a
novel algorithm for efficiently suppressing IQ mixer sidebands to below -30
dBc.

2D van der Waals heterostructures (vdWH) can result in novel functionality
that crucially depends on interfacial structure and disorder. Bubbles at the
vdWH interface can modify the interfacial structure. We probe the dynamics of a
bubble at the interface of a graphene-hBN vdWH by using it as the drumhead of a
NEMS device because nanomechanical devices are exquisite sensors. For drums
with different interfacial bubbles, we measure the evolution of the resonant
frequency and spatial mode shape as a function of electrostatic pulling. We
show that the hysteretic detachment of layers of vdWH is triggered by the
growth of large bubbles. The bubble growth takes place due to the concentration
of stress resembling the initiation of fracture. The small bubbles at the
heterostructure interface do not result in delamination as they are smaller
than a critical fracture length. We provide insight into frictional dynamics
and interfacial fracture of vdWH.

It is known that static traversable wormhole in Einstein gravity is supported
by matter that violates null energy conditions (NEC). Essentially such wormhole
will be characterised by a central throat with anisotropic matter lining the
throat that violates NEC. This in turn provides viable geometry for the
wormhole to sustain. In 2018, L. Herrera introduced a new classification for
spherically symmetric bodies called ``complexity factor". It was proposed that
a spherically symmetric non trivial geometry can be classified as complex or
non-complex based on the nature of the inhomogeneity and anisotropy of the
stress energy tensors with only homogeneous and isotropic matter distribution
leading to null complexity. Mathematically there was also another way of
obtaining zero complexity geometry. In this context since static traversable
wormhole by default is characterised by anisotropic and inhomogeneous matter
stress tensors, the question we answer is whether it is possible to obtain zero
complexity class of wormholes supported by exotic matter.

exponential coupling $e^{a\phi}$ of the dilaton to the Maxwell kinetic term.
Explicit solutions are known only for $a=0$, $a=1$ and $a=\sqrt3$, and for
general $a$ when the electric and magnetic charges $Q$ and $P$ are equal. We
obtain solutions as power series expansions around $Q=P$, in terms of a small
parameter $\epsilon= a^{-1}\, \log(Q/P)$. Using these, and also solutions
constructed numerically, we test a relation between the mass and the charges
that had been conjectured long ago by Rasheed. We find that although the
conjecture is not exactly correct it is in fact quite accurate for a wide range
of the black hole parameters. We investigate some improved conjectures for the
mass relation. We also study the circumstances under which entropy
super-additivity, which is related to Hawking's area theorem, is violated. This
extends beyond previous examples exhibited in the literature for the particular
case of $a=\sqrt3$ dyonic black holes.

Local lens rigidity with incomplete data for a class of non-simple

Let $\sigma$ be the scattering relation on a compact Riemannian manifold $M$
with non-necessarily convex boundary, that maps initial points of geodesic rays
on the boundary and initial directions to the outgoing point on the boundary
and the outgoing direction. Let $\ell$ be the length of that geodesic ray. We
study the question of whether the metric $g$ is uniquely determined, up to an
isometry, by knowledge of $\sigma$ and $\ell$ restricted on some subset $D$. We
allow possible conjugate points but we assume that the conormal bundle of the
geodesics issued from $D$ covers $T^*M$; and that those geodesics have no
conjugate points. Under an additional topological assumption, we prove that
$\sigma$ and $\ell$ restricted to $D$ uniquely recover an isometric copy of $g$
locally near generic metrics, and in particular, near real analytic ones.

Eliminating Mole Size in Melanoma Classification

While skin cancer classification has been a popular and valuable deep
learning application for years, there has been little consideration of the
context in which testing images are taken. Traditional melanoma classifiers
rely on the assumption that their testing environments are analogous to the
structured images on which they are trained. This paper combats this notion,
arguing that mole size, a vital attribute in professional dermatology, is a red
herring in automated melanoma detection. Although malignant melanomas are
consistently larger than benign melanomas, this distinction proves unreliable
and harmful when images cannot be contextually scaled. This implementation
builds a custom model that eliminates size as a training feature to prevent
overfitting to incorrect parameters. Additionally, random rotation and contrast
augmentations are performed to simulate the real-world use of melanoma
detection applications. Several custom models with varying forms of data
augmentation are implemented to demonstrate the most significant features of
the generalization abilities of mole classifiers. These implementations show
that user unpredictability is crucial when utilizing such applications. The
caution required when manually modifying data is acknowledged, as data loss and
biased conclusions are necessary considerations in this process. Additionally,
mole size inconsistency and its significance are discussed in both the
dermatology and deep learning communities.

Molecular Dynamics (MD) simulations of proteins implicitly contain the
information connecting the atomistic molecular structure and proteins'
biologically relevant motion, where large-scale fluctuations are deemed to
guide folding and function. In the complex multiscale processes described by MD
trajectories it is difficult to identify, separate, and study those large-scale
fluctuations. This problem can be formulated as the need to identify a small
number of collective variables that guide the slow kinetic processes. Among the
methods used to study the slow, leading processes in proteins' dynamics, the
time-lagged independent component analysis, or tICA, has been extensively used.
Recently, we developed a Langevin coarse-grained approach for the dynamics of
proteins, called the Langevin Equation for Protein Dynamics or LE4PD. This
approach partitions the protein's MD dynamics into uncorrelated,
wavelength-dependent, diffusive modes, and it associates to each mode a
free-energy map. In the free energy maps, we measure the spatial extension and
the time evolution of the mode-dependent, slow dynamical fluctuations, using
the string method and a Markov state model. The theory identifies the slow
collective variables in the rescaled LE4PD normal modes. Here, we compare the
tICA modes' predictions with the collective LE4PD modes. We observe that the
two methods consistently identify the nature and extension of the slowest
fluctuation processes. The tICA separates the slow, leading processes in a
smaller number of modes than the LE4PD does. However, LE4PD provides
time-dependent information and a formal connection to the physics of the
kinetic processes missing in the pure statistical analysis of tICA.

Two-level domain decomposition preconditioners lead to fast convergence and
scalability of iterative solvers. However, for highly heterogeneous problems,
where the coefficient function is varying rapidly on several possibly
non-separated scales, the condition number of the preconditioned system
generally depends on the contrast of the coefficient function leading to a
deterioration of convergence. Enhancing the methods by coarse spaces
constructed from suitable local eigenvalue problems, also denoted as adaptive
or spectral coarse spaces, restores robust, contrast-independent convergence.
However, these eigenvalue problems typically rely on non-algebraic information,
such that the adaptive coarse spaces cannot be constructed from the fully
assembled system matrix. In this paper, a novel algebraic adaptive coarse
space, which relies on the a-orthogonal decomposition of (local) finite element
(FE) spaces into functions that solve the partial differential equation (PDE)
with some trace and FE functions that are zero on the boundary, is proposed. In
particular, the basis is constructed from eigenmodes of two types of local
eigenvalue problems associated with the edges of the domain decomposition. To
approximate functions that solve the PDE locally, we employ a transfer
eigenvalue problem, which has originally been proposed for the construction of
optimal local approximation spaces for multiscale methods. In addition, we make
use of a Dirichlet eigenvalue problem that is a slight modification of the
Neumann eigenvalue problem used in the adaptive generalized Dryja-Smith-Widlund
(AGDSW) coarse space. Both eigenvalue problems rely solely on local Dirichlet
matrices, which can be extracted from the fully assembled system matrix. By
combining arguments from multiscale and domain decomposition methods we derive
a contrast-independent upper bound for the condition number.

We investigate inflation in modified gravity framework by introducing a
direct coupling term between a scalar field $\phi$ and the trace of the energy
momentum tensor $T$ as $f(\phi,T) = 2 \phi( \kappa^{1/2} \alpha T +
\kappa^{5/2} \beta T^2) $ to the Einstein-Hilbert action. We consider a class
of inflaton potentials (i) $V_0 \phi^p e^{-\lambda\phi}$, (ii) $V_0\frac{
\lambda \phi^p}{1+\lambda\phi^p}$ and investigate the sensitivity of the
modified gravity parameters $\alpha$ and $\beta$ on the inflaton dynamics. We
derive the potential slow-roll parameters, scalar spectral index $n_s$, and
tensor-to-scalar ratio $r$ in the above $f(\phi,T)$ gravity theory and analyze
the following three choices of modified gravity parameters~(i) Case I:~ $\alpha
\neq 0, ~\beta=0$ i.e. neglecting higher order terms, (ii) Case II:~
$\alpha=0$, $\beta \neq 0$~ and do the analysis for $T^2$ term, (iii) Case
III:~ $\alpha \neq 0$ and $\beta \neq 0$ i.e. keeping all terms. For a range of
potential parameters, we obtain constraints on $\alpha$ and $\beta$ in each of
the above three cases using the WMAP and the PLANCK data.

We have studied the structural phase transition of multiferroic YMnO$_3$ from
first principles. Using group-theoretical analysis and first-principles density
functional calculations of the total energy and phonons, we perform a
systematic study of the energy surface around the prototypic phase. We find a
single instability at the zone-boundary which couples strongly to the
polarization. This coupling is the mechanism that allows multiferroicity in
this class of materials. Our results imply that YMnO$_3$ is an improper
ferroelectric. We suggest further experiments to clarify this point.

Statistical properties of interbeat intervals cascade are evaluated by
considering the joint probability distribution $P(\Delta x_2,\tau_2;\Delta
x_1,\tau_1)$ for two interbeat increments $\Delta x_1$ and $\Delta x_2$ of
different time scales $\tau_1$ and $\tau_2$. We present evidence that the
conditional probability distribution $P(\Delta x_2,\tau_2|\Delta x_1,\tau_1)$
may obey a Chapman-Kolmogorov equation. The corresponding Kramers-Moyal (KM)
coefficients are evaluated. It is shown that while the first and second KM
coefficients, i.e., the drift and diffusion coefficients, take on well-defined
and significant values, the higher-order coefficients in the KM expansion are
very small. As a result, the joint probability distributions of the increments
in the interbeat intervals obey a Fokker-Planck equation. The method provides a
novel technique for distinguishing the two classes of subjects in terms of the
drift and diffusion coefficients, which behave differently for two classes of
the subjects, namely, healthy subjects and those with congestive heart failure.

Rescattering effects of baryon and antibaryon in heavy quarkonium decays are
investigated by studying their angular distributions. The rescattering
amplitudes are phenomenologically evaluated by modeling the intermediate range
interaction as a $\sigma$ or pion meson exchange between $\qqbar$ quarks. The
results show that the rescattering effects play an important role in
determination of the angular distribution in heavy quarkonium decays.
Especially, for $J/psi$ and $\psi'$ decays into $\Lambda \bar \Lambda$,
$\Sigma^0\bar \Sigma^0$ and $\Xi^-\bar \Xi^+$ the angular distribution
parameters could turn to be negative values in the limit of helicity
conservation. These results provide us a possible explanation for understanding
the negative sign of the angular distribution parameter measured for $J/psi
\to\Sigma^0\bar\Sigma^0$, namely, {\it it might come from the baryonic
SU(3)$_F$ symmetry breaking by incorporating rescattering effects

Modern internet of things (IoT) devices leverage machine learning inference
using sensed data on-device rather than offloading them to the cloud. Commonly
known as inference at-the-edge, this gives many benefits to the users,
including personalization and security. However, such applications demand high
energy efficiency and robustness. In this paper we propose a method for reduced
area and power overhead of self-timed early-propagative asynchronous inference
circuits, designed using the principles of learning automata. Due to natural
resilience to timing as well as logic underpinning, the circuits are tolerant
to variations in environment and supply voltage whilst enabling the lowest
possible latency. Our method is exemplified through an inference datapath for a
low power machine learning application. The circuit builds on the Tsetlin
machine algorithm further enhancing its energy efficiency. Average latency of
the proposed circuit is reduced by 10x compared with the synchronous
implementation whilst maintaining similar area. Robustness of the proposed
circuit is proven through post-synthesis simulation with 0.25 V to 1.2 V
supply. Functional correctness is maintained and latency scales with gate delay
as voltage is decreased.

The inhomogeneities associated with massless Kalb-Ramond axions can be
amplified not only in isotropic (four-dimensional) string cosmological models
but also in the fully anisotropic case. If the background geometry is
isotropic, the axions (which are not part of the homogeneous background)
develop, outside the horizon, growing modes leading, ultimately, to logarithmic
energy spectra which are "red" in frequency and increase at large distance
scales. We show that this conclusion can be evaded not only in the case of
higher dimensional backgrounds with contracting internal dimensions but also in
the case of string cosmological scenarios which are completely anisotropic in
four dimensions. In this case the logarithmic energy spectra turn out to be
"blue" in frequency and, consequently, decreasing at large distance scales. We
elaborate on anisotropic dilaton-driven models and we argue that, incidentally,
the background models leading to (or flat) logarithmic energy spectra for
axionic fluctuations are likely to be isotropized by the effect of string
tension corrections.

A new, more comprehensive model of gas-grain chemistry in hot molecular cores
is presented, in which nondiffusive reaction processes on dust-grain surfaces
and in ice mantles are implemented alongside traditional diffusive
surface/bulk-ice chemistry. We build on our nondiffusive treatments used for
chemistry in cold sources, adopting a standard collapse/warm-up physical model
for hot cores. A number of other new chemical model inputs and treatments are
also explored in depth, culminating in a final model that demonstrates
excellent agreement with gas-phase observational abundances for many molecules,
including some (e.g. methoxymethanol) that could not be reproduced by
conventional diffusive mechanisms. Observed ratios of structural isomers methyl
formate, glycolaldehyde and acetic acid are well reproduced by the models. The
main temperature regimes are identified in which various complex organic
molecules (COMs) are formed. Nondiffusive chemistry advances the production of
many COMs to much earlier times and lower temperatures than in previous model
implementations. Those species may form either as by-products of simple-ice
production, or via early photochemistry within the ices while external UV
photons can still penetrate. Cosmic ray-induced photochemistry is less
important than in past models, although it affects some species strongly over
long timescales. Another production regime occurs during the high-temperature
desorption of solid water, whereby radicals trapped in the ice are released
onto the grain/ice surface, where they rapidly react. Several recently-proposed
gas-phase COM-production mechanisms are also introduced, but they rarely
dominate. New surface/ice reactions involving CH and CH$_2$ are found to
contribute substantially to the formation of certain COMs.

For any continuous zero-mean random variable (r.v.) X, a reciprocating
function r is constructed, based only on the distribution of X, such that the
conditional distribution of X given the (at-most-)two-point set {X,r(X)} is the
zero-mean distribution on this set; in fact, a more general construction
without the continuity assumption is given in this paper, as well as a large
variety of other related results, including characterizations of the
reciprocating function and modeling distribution asymmetry patterns. The
mentioned disintegration of zero-mean r.v.'s implies, in particular, that an
arbitrary zero-mean distribution is represented as the mixture of two-point
zero-mean distributions; moreover, this mixture representation is most
symmetric in a variety of senses. Somewhat similar representations -- of any
probability distribution as the mixture of two-point distributions with the
same skewness coefficient (but possibly with different means) -- go back to
Kolmogorov; very recently, Aizenman et al. further developed such
representations and applied them to (anti-)concentration inequalities for
functions of independent random variables and to spectral localization for
random Schroedinger operators. One kind of application given in the present
paper is to construct certain statistical tests for asymmetry patterns and for
location without symmetry conditions. Exact inequalities implying conservative
properties of such tests are presented. These developments extend results
established earlier by Efron, Eaton, and Pinelis under a symmetry condition.

We calculate the two-photon 1S-2S spectrum of an atomic hydrogen
Bose-Einstein condensate in the regime where the cold collision frequency shift
dominates the lineshape. WKB and static phase approximations are made to find
the intensities for transitions from the condensate to motional eigenstates for
2S atoms. The excited state wave functions are found using a mean field
potential which includes the effects of collisions with condensate atoms.
Results agree well with experimental data. This formalism can be used to find
condensate spectra for a wide range of excitation schemes.

The Gerasimov-Drell-Hearn sum rule is one of several dispersive sum rules
that connect the Compton scattering amplitudes to the inclusive photoproduction
cross sections of the target under investigation. Being based on such universal
principles as causality, unitarity, and gauge invariance, these sum rules
provide a unique testing ground to study the internal degrees of freedom that
hold the system together. The present article reviews these sum rules for the
spin-dependent cross sections of the nucleon by presenting an overview of
recent experiments and theoretical approaches. The generalization from real to
virtual photons provides a microscope of variable resolution: At small
virtuality of the photon, the data sample information about the long range
phenomena, which are described by effective degrees of freedom (Goldstone
bosons and collective resonances), whereas the primary degrees of freedom
(quarks and gluons) become visible at the larger virtualities. Through a rich
body of new data and several theoretical developments, a unified picture of
virtual Compton scattering emerges, which ranges from coherent to incoherent
processes, and from the generalized spin polarizabilities on the low-energy
side to higher twist effects in deep inelastic lepton scattering.

We report time-resolved measurements of magnetization switching by spin-orbit
torques in the absence of an external magnetic field in perpendicularly
magnetized magnetic tunnel junctions (MTJ). Field-free switching is enabled by
the dipolar field of an in-plane magnetized layer integrated above the MTJ
stack, the orientation of which determines the switching polarity. Real-time
single-shot measurements provide direct evidence of magnetization reversal and
switching distributions. Close to the critical switching voltage we observe
stochastic reversal events due to a finite incubation delay preceding the
magnetization reversal. Upon increasing the pulse amplitude to twice the
critical voltage the reversal becomes quasi-deterministic, leading to reliable
bipolar switching at sub-ns timescales in zero external field. We further
investigate the switching probability as a function of dc bias of the MTJ and
external magnetic field, providing insight on the parameters that determine the
critical switching voltage.

The apertureless SNOM mapping of the slightly-doped 4H-SiC epitaxial layer
grown on a heavily-doped 4H-SiC substrate was performed with a cleaved edge
geometry. ASNOM images taken at the light frequencies of a $C^{13}O_{2}^{16}$
laser show a clear contrast between the substrate and the epitaxial layer. The
contrast vanishes at the laser frequency of $884cm^{-1}$, and gets clearer at
higher frequencies $(923cm^{-1})$. This can be explained by changes in the
local polarizability of SiC caused by the carrier concentration, which are more
pronounced at higher frequencies. Since the light frequency is tuned up further
($935cm^{-1}$), a transversal mode structure appears in the ASNOM map,
indicating a waveguide-like confinement of a surface phonon polariton wave
inside the strip of an epi-layer outcrop.

We study on dynamics of high-order rogue wave in two-component coupled
nonlinear Schr\"{o}dinger equations. We find four fundamental rogue waves can
emerge for second-order vector RW in the coupled system, in contrast to the
high-order ones in single component systems. The distribution shape can be
quadrilateral, triangle, and line structures through varying the proper initial
excitations given by the exact analytical solutions. Moreover, six fundamental
rogue wave can emerge on the distribution for second-order vector rogue wave,
which is similar to the scalar third-order ones. The distribution patten for
vector ones are much abundant than the ones for scalar rogue waves. The results
could be of interest in such diverse fields as Bose-Einstein condensates,
nonlinear fibers, and superfluids.

An extended $1$-perfect trade is a pair $(T_0,T_1)$ of two disjoint binary
distance-$4$ even-weight codes such that the set of words at distance $1$ from
$T_0$ coincides with the set of words at distance $1$ from $T_1$. Such trade is
called primary if any pair of proper subsets of $T_0$ and $T_1$ is not a trade.
Using a computer-aided approach, we classify nonequivalent primary extended
$1$-perfect trades of length $10$, constant-weight extended $1$-perfect trades
of length $12$, and Steiner trades derived from them. In particular, all
Steiner trades with parameters $(5,6,12)$ are classified.

Globular proteins undergo thermal fluctuations in solution, while maintaining
an overall well-defined folded structure. In particular, studies have shown
that the core structure of globular proteins differs in small, but significant
ways when they are solved by x-ray crystallography versus solution-based NMR
spectroscopy. Given these discrepancies, it is unclear whether molecular
dynamics (MD) simulations can accurately recapitulate protein conformations. We
therefore perform extensive MD simulations across multiple force fields and
sampling techniques to investigate the degree to which computer simulations can
capture the ensemble of conformations observed in experiments. By analyzing
fluctuations in the atomic coordinates and core packing, we show that
conformations sampled in MD simulations both move away from and sample a larger
conformational space than the ensemble of structures observed in NMR
experiments. However, we find that adding inter-residue distance restraints
that match those obtained via Nuclear Overhauser Effect measurements enables
the MD simulations to sample more NMR-like conformations, though significant
differences between the core packing features in restrained MD and the NMR
ensemble remain. Given that the protein structures obtained from the MD
simulations possess smaller and less dense protein cores compared to those
solved by NMR, we suggest that future improvements to MD forcefields should aim
to increase the packing of hydrophobic residues in protein cores.

We measure stretched exponential behavior, exp(- (t/t_0)**beta), over many
decades in a one-dimensional array of coupled chaotic electronic elements just
above a crisis-induced intermittency transition. There is strong spatial
heterogeneity and individual sites display a dynamics ranging from near power
law ($\beta=0$) to near exponential ($\beta=1$) while the global dynamics,
given by a spatial average, remains stretched exponential. These results can be
reproduced quantitatively with a one-dimensional coupled-map lattice and thus
appear to be system independent. In this model, local stretched exponential
dynamics is achieved without frozen disorder and is a fundamental property of
the coupled system. The heterogeneity of the experimental system can be
reproduced by introducing quenched disorder in the model. This suggests that
the stretched exponential dynamics can arise as a purely chaotic phenomenon.

This paper studies the effect of independent additive noise on the
synchronous dynamics of large populations of globally coupled maps. Our
analysis is complementary to the approach taken by Teramae and Kuramoto
[Teramae and Kuramoto, Phys. Rev. E 63:036210, 2001] who pointed out the
anomalous scaling properties preceding the loss of coherence. We focus on the
macroscopic dynamics that remains deterministic at any noise level and differs
from the microscopic one. Using properly defined order parameters, an
analytical approach is proposed for describing the collective dynamics in terms
of an approximate low-dimensional system. The systematic derivation of the
macroscopic equations provides a link between the microscopic features of the
population (single-element dynamics and noise distribution) and the properties
of the emergent behaviour. The macroscopic bifurcations induced by noise are
compared to those originating from parameter mismatches within the population.

Quantifying the eddy-jet feedback strength of the annular mode in an

A linear response function (LRF) that relates the temporal tendency of zonal
mean temperature and zonal wind to their anomalies and external forcing is used
to accurately quantify the strength of the eddy-jet feedback associated with
the annular mode in an idealized GCM. Following a simple feedback model, the
results confirm the presence of a positive eddy-jet feedback in the annular
mode dynamics, with a feedback strength of 0.137 day$^{-1}$ in the idealized
GCM. Statistical methods proposed by earlier studies to quantify the feedback
strength are evaluated against results from the LRF. It is argued that the
mean-state-independent eddy forcing reduces the accuracy of these statistical
methods because of the quasi-oscillatory nature of the eddy forcing. A new
method is proposed to approximate the feedback strength as the regression
coefficient of low-pass filtered eddy forcing onto low-pass filtered annular
mode index, which converges to the value produced by the LRF when timescales
longer than 200 days are used for the low-pass filtering. Applying the new
low-pass filtering method to the reanalysis data, the feedback strength in the
Southern annular mode is found to be 0.121 day$^{-1}$, which is presented as an
improvement over previous estimates. This work also highlights the importance
of using sub-daily data in the analysis by showing the significant contribution
of medium-scale waves of periods less than 2 days to the annular mode dynamics,
which was under-appreciated in most of previous research. The present study
provides a framework to quantify the eddy-jet feedback strength in models and
reanalysis data.

We construct supersymmetric compactifications of E_8 \times E_8 heterotic
string theory which realise exactly the massless spectrum of the Minimal
Supersymmetric Standard Model (MSSM) at low energies. The starting point is the
standard embedding on a Calabi-Yau threefold which has Hodge numbers
(h^11,h^21) = (1,4) and fundamental group Z_12, which gives an E_6 grand
unified theory with three net chiral generations. The gauge symmetry is then
broken to that of the standard model by a combination of discrete Wilson lines
and continuous deformation of the gauge bundle. On eight distinct branches of
the moduli space, we find stable bundles with appropriate cohomology groups to
give exactly the massless spectrum of the MSSM.

In this paper we establish an abstract, dynamical Thouless-type formula for
affine families of $\mathrm{GL} (2,\mathbb{R})$ cocycles. This result extends
the classical formula relating, via the Hilbert transform, the maximal Lyapunov
exponent and the integrated density of states of a Schr\"odinger operator.
Here, the role of the integrated density of states will be played by a more
geometrical quantity, the fibered rotation number. As an application of this
formula we present limitations on the modulus of continuity of random linear
cocycles. Moreover, we derive H\"older-type continuity properties of the
fibered rotation number for linear cocycles over various base dynamics.

We introduce a class of polytopes that we call chainlink polytopes and which
allow us to construct infinite families of pairs of non isomorphic rational
polytopes with the same Ehrhart quasi-polynomial. Our construction is based on
circular fence posets, which admit a non-obvious and non-trivial symmetry in
their rank sequences that turns out to be reflected in the polytope level. We
introduce the related class of chainlink posets and show that they exhibit the
same symmetry properties. We further prove an outstanding conjecture on the
unimodality of circular rank polynomials.

Quantum coherence is a central ingredient in quantum physics with several
theoretical and technological ramifications. In this work we consider a figure
of merit encoding the information on how the coherence generated on average by
a quantum gate is affected by unitary errors (coherent noise sources). We
provide numerical evidences that such information is well captured by the
statistics of local energy measurements on the output states of the gate. These
findings are then corroborated by experimental data taken in a quantum optics
setting.

The effect of ring vortices on the destabilization of supersaturated liquid
helium mixtures at very low temperatures is investigated as a function of
pressure. We have found that large ring vortices trigger the segregation of 3He
at smaller values of the concentration than small ring vortices. Our
calculations indicate that the existence of ring vortices in the mixture is a
possible mechanism to understand the rather small degree of critical
supersaturation found in the experiments.
