We study the national production of academic knowledge in all Iberoamerican
countries (IAC) between 1973 and 2007. We show that the total number of
mainstream scientific publications listed in SCI,SSCI and A&HCI follows an
exponential growth, the same as the national productivity expressed in the
number of publications per capita. We also explore the temporal evolution of
the co-authorship patterns between a sample of 12 IAC responsible for 98% of
the total regional publications, with a group of other 45 nations. We show that
the scientific co-authorship among countries follows a power-law and behaves as
a self-organizing scale-free network, where each country appears as a node and
each co-publication as a link. We develop a mathematical model to study the
temporal evolution of co-authorship networks, based on a preferential
attachment strategy and we show that the number of co-publications among
countries growths quadraticly against time. We empirically determine the
quadratic growth constants for 352 different networks within. We corroborate
that the connectivity of regional countries with larger scientific networks is
growing faster than with other less connected countries. We determine the
dates, at which the co-authorship connectivities trigger the self-organizing
scale free network for each of the 352 cases. We find that the last follows a
normal distribution around year 1981.4 +/-2.2 and we connect the last effect
with a brain-drainage process generated in the region. We show how the number
of co-publications Pki (t) between country k and country i, is related with a
power-law against the coupling growth coefficients aki.

We calculate, in the continuum limit of quenched lattice QCD, the form factor
that enters in the decay rate of the semileptonic decay B --> D l nu. Making
use of the step scaling method (SSM), previously introduced to handle two scale
problems in lattice QCD, and of flavour twisted boundary conditions we extract
G(w) at finite momentum transfer and at the physical values of the heavy quark
masses. Our results can be used in order to extract the CKM matrix element Vcb
by the experimental decay rate without model dependent extrapolations.

This paper introduces a hybrid pilot-aided channel estimation technique for
mitigating the effect of pilot contamination for the uplink of multi-cell
multiuser massive MIMO systems. The proposed hybrid pilot is designed such that
it enjoys the complementary advantages between time-multiplexed (TM) pilot and
time-superimposed (TS) pilot, and thereby, allows superior solution to the
conventional pilot schemes. We mathematically characterize the impact of hybrid
pilot on the massive MIMO uplink by deriving a closed-form approximation for
the uplink achievable rate. In large-number-of-antennas regime, we obtain the
asymptotically optimal solution for hybrid pilot by jointly designing the TM
pilot and the TS pilot. It is shown that either TM pilot or TS pilot has the
advantages for large frame-size and limited frame-size transmission,
respectively, while the hybrid pilot scheme can offer a superior performance to
that employing either TM pilot or TS pilot. Numerical results demonstrate the
effectiveness of the proposed design.

The singular value decomposition (SVD) is a popular matrix factorization that
has been used widely in applications ever since an efficient algorithm for its
computation was developed in the 1970s. In recent years, the SVD has become
even more prominent due to a surge in applications and increased computational
memory and speed.
To illustrate the vitality of the SVD in data analysis, we highlight three of
its lesser-known yet fascinating applications: the SVD can be used to
characterize political positions of Congressmen, measure the growth rate of
crystals in igneous rock, and examine entanglement in quantum computation. We
also discuss higher-dimensional generalizations of the SVD, which have become
increasingly crucial with the newfound wealth of multidimensional data and have
launched new research initiatives in both theoretical and applied mathematics.
With its bountiful theory and applications, the SVD is truly extraordinary.

of such a high energy ERL is studied based on the simulation on a 3-GeV ERL
light source proposed by KEK. It is expected to provide a reference to the

WildMix Dataset and Spectro-Temporal Transformer Model for Monoaural
Audio Source Separation

Monoaural audio source separation is a challenging research area in machine
learning. In this area, a mixture containing multiple audio sources is given,
and a model is expected to disentangle the mixture into isolated atomic
sources. In this paper, we first introduce a challenging new dataset for
monoaural source separation called WildMix. WildMix is designed with the goal
of extending the boundaries of source separation beyond what previous datasets
in this area would allow. It contains diverse in-the-wild recordings from 25
different sound classes, combined with each other using arbitrary composition
policies. Source separation often requires modeling long-range dependencies in
both temporal and spectral domains. To this end, we introduce a novel
trasnformer-based model called Spectro-Temporal Transformer (STT). STT utilizes
a specialized encoder, called Spectro-Temporal Encoder (STE). STE highlights
temporal and spectral components of sources within a mixture, using a
self-attention mechanism. It subsequently disentangles them in a hierarchical
manner. In our experiments, STT swiftly outperforms various previous baselines
for monoaural source separation on the challenging WildMix dataset.

On the Similarity between von Neumann Graph Entropy and Structural
Information: Interpretation, Computation, and Applications
|

The von Neumann graph entropy is a measure of graph complexity based on the
Laplacian spectrum. It has recently found applications in various learning
tasks driven by networked data. However, it is computational demanding and hard
to interpret using simple structural patterns. Due to the close relation
between Lapalcian spectrum and degree sequence, we conjecture that the
structural information, defined as the Shannon entropy of the normalized degree
sequence, might be a good approximation of the von Neumann graph entropy that
is both scalable and interpretable.
In this work, we thereby study the difference between the structural
information and von Neumann graph entropy named as {\em entropy gap}. Based on
the knowledge that the degree sequence is majorized by the Laplacian spectrum,
we for the first time prove the entropy gap is between $0$ and $\log_2 e$ in
any undirected unweighted graphs. Consequently we certify that the structural
information is a good approximation of the von Neumann graph entropy that
achieves provable accuracy, scalability, and interpretability simultaneously.
This approximation is further applied to two entropy-related tasks: network
design and graph similarity measure, where novel graph similarity measure and
fast algorithms are proposed. Our experimental results on graphs of various
scales and types show that the very small entropy gap readily applies to a wide
range of graphs and weighted graphs. As an approximation of the von Neumann
graph entropy, the structural information is the only one that achieves both
high efficiency and high accuracy among the prominent methods. It is at least
two orders of magnitude faster than SLaQ with comparable accuracy. Our
structural information based methods also exhibit superior performance in two
entropy-related tasks.

Starting from the three-band $p-d$ Hubbard Hamiltonian we derive an effective
$t-J$ model including electron-phonon interaction of quasiparticles with
optical phonons. Within the effective Hamiltonian we analyze the influence of
electronic correlations and electron-phonon interaction on the dynamical spin
susceptibility in layered cuprates. We find a huge isotope effect on the
resonance peak in the magnetic spin susceptibility, ${Im}\chi({\bf q},\omega)$,
seen by inelastic neutron scattering. It results from both the electron-phonon
coupling and the electronic correlation effects taken into account beyond
random phase approximation(RPA) scheme. We find at optimal doping the isotope
coeffiecient $\alpha_{res} \approx 0.35$ which can be further tested
experimentally.

We report the discovery made using the Australia Telescope Compact Array of a
remarkable string of radio emission towards IRAS 16562-3959, a luminous
infrared source with a bolometric luminosity of $7.0\times10^4$ \Lsun. The
radio emission arises from a compact, bright central component, two inner
lobes, which are separated by about 7\arcsec\ and symmetrically offset from the
central source, and two outer lobes which are separated by about 45\arcsec. The
emission from the central object has a spectral index between 1.4 and 8.6 GHz
of $0.85\pm0.15$, consistent with free-free emission from a thermal jet. The
radio emission from the lobes have spectral indices in the range characteristic
of thermal emission. We suggest that the emission from the lobes arises in
shocks resulting from the interaction of a collimated wind with the surrounding
medium. The radio string is located within a massive dense molecular core, and
is associated with extended green emission (Spitzer 3-color), Herbig-Haro type
emission (2MASS K$_s$-band) and OH maser sites -- all phenomena readily
observed towards sites of massive star formation. We conclude that the massive
core hosts a high-mass star in an early stage of evolution in which it is
undergoing the ejection of a powerful collimated stellar wind, showing that
jets found in the formation of low-mass stars are also produced in high-mass
stars.

HL-Net: Heterophily Learning Network for Scene Graph Generation
|
Accepted to CVPR 2022

Scene graph generation (SGG) aims to detect objects and predict their
pairwise relationships within an image. Current SGG methods typically utilize
graph neural networks (GNNs) to acquire context information between
objects/relationships. Despite their effectiveness, however, current SGG
methods only assume scene graph homophily while ignoring heterophily.
Accordingly, in this paper, we propose a novel Heterophily Learning Network
(HL-Net) to comprehensively explore the homophily and heterophily between
objects/relationships in scene graphs. More specifically, HL-Net comprises the
following 1) an adaptive reweighting transformer module, which adaptively
integrates the information from different layers to exploit both the
heterophily and homophily in objects; 2) a relationship feature propagation
module that efficiently explores the connections between relationships by
considering heterophily in order to refine the relationship representation; 3)
a heterophily-aware message-passing scheme to further distinguish the
heterophily and homophily between objects/relationships, thereby facilitating
improved message passing in graphs. We conducted extensive experiments on two
public datasets: Visual Genome (VG) and Open Images (OI). The experimental
results demonstrate the superiority of our proposed HL-Net over existing
state-of-the-art approaches. In more detail, HL-Net outperforms the second-best
competitors by 2.1$\%$ on the VG dataset for scene graph classification and
1.2$\%$ on the IO dataset for the final score. Code is available at
https://github.com/siml3/HL-Net.

We apply the multicanonical technique to the three dimensional dynamical
triangulation model, which is known to exhibit a first order phase transition
with the Einstein-Hilbert action. We first clarify the first order nature of
the phase transition with the Einstein-Hilbert action in several ways including
a high precision finite size scaling analysis. We then add a new local term to
the action and confirm the conjecture made through the MCRG technique that the
line of the first order phase transition extends to the expanded phase diagram,
ending at a point. Fractal dimension at the end point is measured to be around
three up to the present size.

The direct problem of optoacoustic signal generation in biological media
consists of solving the inhomogeneous optoacoustic wave equation for an initial
acoustic stress profile. In contrast, the mathematically challenging inverse
problem requires the reconstruction of the initial stress profile from a proper
set of observed signals. In this article, we consider the particular case of a
Gaussian transverse irradiation source profile in the paraxial approximation of
the wave equation, for which the direct problem along the beam axis can be cast
into a linear Volterra integral equation of the second kind. This integral
equation can be used in two ways: as a forward solver to predict optoacoustic
signals in terms of the direct problem, and as an inverse solver for which we
here devise highly efficient numerical schemes used for the reconstruction of
initial pressure profiles from observed signals, constituting a methodical
progress of computational aspects of optoacoustics. In this regard, we explore
the validity as well as the limits of the inversion scheme via numerical
experiments, with parameters geared towards actual optoacoustic problem
instances. The considered inversion input consists of synthetic data, obtained
by means of forward solvers based on the Volterra integral, and, more
generally, the optoacoustic Poisson integral. Regarding the latter, we
numerically invert signals that correspond to different detector-to-sample
distances and assess the convergence to the true initial stress profiles upon
approaching the far-field. Finally, we also address the effect of noise on the
quality of the reconstructed pressure profiles.

We propose a decentralized conceptual marketplace model for IoT generated
personal data. Our model is based on a thorough analysis of personal data in a
marketplace context, with specific focus on the challenges presented by
commercializing IoT generated personal data. Our model introduces a novel
perspective on the commercialization of personal data for a marketplace context
via risk evaluation and a data licensing framework. We have designed our model
to be centered around protecting the privacy and data rights of data generators
through model components that effectively assess and modify transaction risks,
and formalize transaction agreements by establishing rights of data use and
access between buyer and seller. Our model could serve as a blueprint to inform
the implementation of a personal data marketplace that respects privacy and
ownership.

The sea quark content of the $\Sigma^+$ baryon is investigated using
light-cone baryon-meson fluctuation model suggested by Brodsky and Ma. It is
found that the $\Sigma^+$ sea is flavour asymmetric ($\dbar > \ubar > \sbar$)
and quark-antiquark asymmetric ($q \not= \qbar$). Our prediction for the
flavour asymmetry, $\dbar > \ubar > \sbar$, is significantly different from the
SU(3) prediction ($\dbar < \ubar < \sbar$), while our prediction for the
$d$-$\dbar$ asymmetry is consistent with the SU(3) prediction.

We explore the properties of a system of run-and-tumble (RnT) particles
moving in a piecewise-linear ``ratchet'' potential, and subject to
non-negligible diffusion, by deriving exact analytical results for its
steady-state probability density, current, entropy production rate, power
output, and thermodynamic efficiency. The current, and thus the extractable
power and efficiency, have non-monotonic dependencies on the diffusion
strength, ratchet height, and particle self-propulsion speed, peaking at finite
values in each case. In the case where the particles' self-propulsion is
completely suppressed by the force from the ratchet, and thus a current can be
generated only by diffusion-mediated barrier crossings, the system's entropy
production rate remains finite in the limit of vanishing diffusion. In the
final part of this work, we consider RnT motion in a linear ratchet potential
on a bounded interval, allowing the derivation of mean first-passage times and
splitting probabilities for different boundary and initial conditions. The
present work resides at the interface of exactly solvable models of
run-and-tumble motion and the study of work extraction from active matter by
providing exact expressions pertaining to the feasibility and future design of
active engines. Our results are in agreement with Monte Carlo simulations.

The transport and deposition of heavy particles in complex terrain:
insights from an Eulerian model for large eddy simulation
| null | null | null | null |

The transport and deposition of heavy particles over complex surface
topography by turbulent fluid flow is an important problem in a number of
disciplines, including sediment and snow transport, ecology and plant
pathology, aeolian processes, and geomorphology. This article presents a
framework to simulate the transport and deposition of heavy particles over
complex surfaces using the large eddy simulation (LES) technique. An immersed
boundary LES code is coupled with an Eulerian particle code that solves the
advection-diffusion equation for the resolved particle concentration field. The
mass conservation equation for the particle phase is discretized in a finite
volume framework using a Cartesian cut cell method that reshapes finite volume
cells intersected by the immersed boundary surface and conserves mass
accurately. The proposed numerical model is compared with data from wind tunnel
experiments of heavy particle deposition over topography and is found to have
good agreement with observed deposition patterns. An LES case study of snow
deposition over idealized topography leads to several new insights. Particle
inertia leads to relative velocities between the particles and fluid in regions
of mean flow acceleration, thereby enhancing deposition on the windward side of
obstacles and suppressing deposition on the leeward side. In addition, it is
found that the mean components of particle inertia are a factor of 6 or more
larger than the turbulent components, indicating that the
enhancement/suppression of deposition by topography can be modeled in terms of
mean flow quantities.

In this chapter we studied the nonlinear co-movements between the Mexican
Crude Oil price, the Mexican Stock Market Index and the USD/MXN Exchange Rate,
for the sample period from 1994 to date. We used a battery of nonlinear tests,
cf. (Patterson & Ashley, 2000) and one multivariate test, in order to determine
the dynamic co-movement exerted from the oil prices to the stock and exchange
rate markets. Such co-movement and time windows are exposed using the Brooks &
Hinich (1999) cross- bicorrelation statistical test. The effects of oil spills
on other markets have been studied from different angles and on several
financial assets. In this study, we focus our attention on the detection, not
only of the correlations amongst markets but on the epochs in which such
nonlinear dependence might occur. This is important in order to understand
better, how the markets that drive the economy interact with each other. We
hope to contribute to the literature with such findings, filling a gap in the
emerging markets context, in particular, for the Mexican case.

A trace formula for Toeplitz operators was proved by Boutet de Monvel and
Guillemin in the setting of general Toeplitz structures. Here we give a local
version of this result for a class of Toeplitz operators related to continuous
groups of symmetries on quantizable compact symplectic manifolds. The local
trace formula involves certain scaling asymptotics along the clean fixed locus
of the Hamiltonian flow of the symbol, reminiscent of the scaling asymptotics
of the equivariant components of the Szeg\"o kernel along the diagonal.

Machine learning model weights and activations are represented in
full-precision during training. This leads to performance degradation in
runtime when deployed on neural network accelerator (NNA) chips, which leverage
highly parallelized fixed-point arithmetic to improve runtime memory and
latency. In this work, we replicate the NNA operators during the training
phase, accounting for the degradation due to low-precision inference on the NNA
in back-propagation. Our proposed method efficiently emulates NNA operations,
thus foregoing the need to transfer quantization error-prone data to the
Central Processing Unit (CPU), ultimately reducing the user perceived latency
(UPL). We apply our approach to Recurrent Neural Network-Transducer (RNN-T), an
attractive architecture for on-device streaming speech recognition tasks. We
train and evaluate models on 270K hours of English data and show a 5-7%
improvement in engine latency while saving up to 10% relative degradation in
WER.

Circuit QED on a chip has become a powerful platform for simulating complex
many-body physics. In this report, we realize a Dicke-Ising model with an
antiferromagnetic nearest-neighbor spin-spin interaction in circuit QED with a
superconducting qubit array. We show that this system exhibits a competition
between the collective spin-photon interaction and the antiferromagnetic
nearest-neighbor spin-spin interaction, and then predict four quantum phases,
including: a paramagnetic normal phase, an antiferromagnetic normal phase, a
paramagnetic superradiant phase, and an antiferromagnetic superradiant phase.
The antiferromagnetic normal phase and the antiferromagnetic superradiant phase
are new phases in many-body quantum optics. In the antiferromagnetic
superradiant phase, both the antiferromagnetic and superradiant orders can
coexist, and thus the system possesses $Z_{2}^{z}\otimes Z_{2}$\ symmetry.
Moreover, we find an unconventional photon signature in this phase. In future
experiments, these predicted quantum phases could be distinguished by detecting
both the mean-photon number and the magnetization.

Scientific publications and other genres of research output are increasingly
being cited in policy documents. Citations in documents of this nature could be
considered a critical indicator of the significance and societal impact of the
research output. In this study, we built classification models that predict
whether a particular research work is likely to be cited in a public policy
document based on the attention it received online, primarily on social media
platforms. We evaluated the classifiers based on their accuracy, precision, and
recall values. We found that Random Forest and Multinomial Naive Bayes
classifiers performed better overall.

We have theoretically designed three families of the half-metallic (HM)
antiferromagnets (AFM), namely, La$A$VOsO$_6$, La$A$MoTcO$_6$ and
La$A$MoReO$_6$ ($A$ = Ca, Sr, Ba), based on a systematic {\it ab initio} study
of the ordered double perovskites La$ABB'$O$_6$ with the possible $B$ and $B'$
pairs from all the 3$d$, 4$d$ and 5$d$ transtion metal elements being
considered. Electronic structure calculations based on first-principles
density-functional theory with generalized gradient approximation (GGA) for
more than sixty double perovskites LaCa$BB'$O$_6$ have been performed using the
all-electron full-potential linearized augmented-plane-wave method. The found
HM-AFM state in these materials survives the full {\it ab initio} lattice
constant and atomic position optimizations which were carried out using
frozen-core full potential projector augmented wave method. It is found that
the HM-AFM properties predicted previously in some of the double perovskites
would disappear after the full structural optimizations. The AFM is attributed
to both the superexchange mechanism and the generalized double exchange
mechanism via the $B$ ($t_{2g}$) - O (2$p_{\pi}$) - $B'$ ($t_{2g}$) coupling
and the latter is also believed to be the origin of the HM. Finally, in our
search for the HM-AFMs, we find La$A$CrTcO$_6$ and La$A$CrReO$_6$ to be AFM
insulators of an unconventional type in the sense that the two
antiferromagnetic coupled ions consist of two different elements and that the
two spin-resolved densities of states are no longer the same.

HD 15137 is an intriguing runaway O-type binary system that offers a rare
opportunity to explore the mechanism by which it was ejected from the open
cluster of its birth. Here we present recent blue optical spectra of HD 15137
and derive a new orbital solution for the spectroscopic binary and physical
parameters of the O star primary. We also present the first XMM-Newton
observations of the system. Fits of the EPIC spectra indicate soft, thermal
X-ray emission consistent with an isolated O star. Upper limits on the
undetected hard X-ray emission place limits on the emission from a proposed
compact companion in the system, and we rule out a quiescent neutron star in
the propellor regime or a weakly accreting neutron star. An unevolved secondary
companion is also not detected in our optical spectra of the binary, and it is
difficult to conclude that a gravitational interaction could have ejected this
runaway binary with a low mass optical star. HD 15137 may contain an elusive
neutron star in the ejector regime or a quiescent black hole with conditions
unfavorable for accretion at the time of our observations.

Contemporary segmentation methods are usually based on deep fully
convolutional networks (FCNs). However, the layer-by-layer convolutions with a
growing receptive field is not good at capturing long-range contexts such as
lane markers in the scene. In this paper, we address this issue by designing a
distillation method that exploits label structure when training segmentation
network. The intuition is that the ground-truth lane annotations themselves
exhibit internal structure. We broadcast the structure hints throughout a
teacher network, i.e., we train a teacher network that consumes a lane label
map as input and attempts to replicate it as output. Then, the attention maps
of the teacher network are adopted as supervisors of the student segmentation
network. The teacher network, with label structure information embedded, knows
distinctly where the convolution layers should pay visual attention into. The
proposed method is named as Label-guided Attention Distillation (LGAD). It
turns out that the student network learns significantly better with LGAD than
when learning alone. As the teacher network is deprecated after training, our
method do not increase the inference time. Note that LGAD can be easily
incorporated in any lane segmentation network.

We study the motion of solitary-wave solutions of a family of focusing
generalized nonlinear Schroedinger equations with a confining, slowly varying
external potential, $V(x)$. A Lyapunov-Schmidt decomposition of the solution
combined with energy estimates allows us to control the motion of the solitary
wave over a long, but finite, time interval. We show that the center of mass of
the solitary wave follows a trajectory close to that of a Newtonian point
particle in the external potential $V(x)$ over a long time interval.

A new statistical based model approach to characterize a user's behavior in
an Internet access link is presented. The real patterns of Internet traffic in
a heterogeneous Campus Network are studied. We find three clearly different
patterns of individual user's behavior, study their common features and group
particular users behaving alike in three clusters. This allows us to build a
probabilistic mixture model, that can explain the expected global behavior for
the three different types of users. We discuss the implications of this
emergent phenomenology in the field of multi-agent complex systems.

Trust is often cited as an essential criterion for the effective use and
real-world deployment of AI. Researchers argue that AI should be more
transparent to increase trust, making transparency one of the main goals of
XAI. Nevertheless, empirical research on this topic is inconclusive regarding
the effect of transparency on trust. An explanation for this ambiguity could be
that trust is operationalized differently within XAI. In this position paper,
we advocate for a clear distinction between behavioral (objective) measures of
reliance and attitudinal (subjective) measures of trust. However, researchers
sometimes appear to use behavioral measures when intending to capture trust,
although attitudinal measures would be more appropriate. Based on past
research, we emphasize that there are sound theoretical reasons to keep trust
and reliance separate. Properly distinguishing these two concepts provides a
more comprehensive understanding of how transparency affects trust and
reliance, benefiting future XAI research.

We define a variation on the well-known problem of private message
transmission. This new problem called private randomness agreement (PRA) gives
two participants access to a public, authenticated channel alongside the main
channels, and the 'message' is not fixed a priori.
Instead, the participants aim to agree on a random string completely unknown
to a computationally unbounded adversary.
We define privacy and reliability, and show that PRA cannot be solved in a
single round. We then show that it can be solved in three rounds, albeit with
exponential cost, and give an efficient four-round protocol based on polynomial
evaluation.

The dependence of breakup cross sections of 8B at 65 MeV/nucleon on the
target mass number A_T is investigated by means of the continuum-discretized
coupled-channels method (CDCC) with more reliable distorting potentials than
those in the preceding study. The A_T^(1/3) scaling law of the nuclear breakup
cross section is found to be satisfied only in the middle A_T region of 40 <
A_T < 150. The interference between nuclear and Coulomb breakup amplitudes
vanishes in very forward angle scattering, independently of the target nucleus.
The truncation of the relative energy between the p and 7Be fragments slightly
reduces the contribution of nuclear breakup at very forward angles, while the
angular region in which the first-order perturbation theory works well does not
change essentially.

Wave propagation dynamics inside a complex scattering medium by the
temporal control of backscattered waves
| null | null | null | null |

|
Shaping the wavefront of an incident wave to a complex scattering medium has
demonstrated interesting possibilities, such as sub-diffraction wave focusing
and enhancing light energy delivery. However, wavefront shaping has mainly been
based on the control of transmitted waves that are inaccessible in most
realistic applications. Here, we investigate the effect of maximizing the
backscattered waves at a specific flight time on wave propagation dynamics and
energy transport. We find both experimentally and numerically that the
maximization at a short flight time focuses waves on the particles constituting
the scattering medium, leading to the attenuation of the wave transport. On the
contrary, maximization at a long flight time induces constructive wave
interference inside the medium and thus enhances wave transport. We provide a
theoretical model explaining this interesting transition behavior based on wave
correlation. Our study provides a fundamental understanding of the effect of
wave control on internal wave dynamics.

ZnO-based scintillation ceramics for application in HENPA LENPA analyzers
have been investigated. The following ceramic samples have been prepared:
undoped ones (ZnO), an excess of zinc in stoichiometry (ZnO:Zn), doped with
gallium (ZnO:Ga) and lithium (ZnO:Li). Optical transmission, x-ray excited
emission, scintillation decay and pulse height spectra were measured and
analyzed. Ceramics have reasonable transparency in visible range (up to 60% for
0.4 mm thickness) and energy resolution (14.9% at 662 keV Cs137 gamma
excitation). Undoped ZnO shows slow (1.6 {\mu}s) luminescence with maximum at
2.37 eV and light yield about 57% of CsI:Tl. ZnO:Ga ceramics show relatively
low light yield with ultra fast decay time (1 ns). Lithium doped ceramics
ZnO:Li have better decay time than undoped ZnO with fair light yield. ZnO:Li
ceramics show good characteristics under alpha-particle excitation and can be
applied for the neutral particle analyzers.

We study boundary effects in a linear wave equation with Dirichlet type
conditions in a weakly curved pipe. The coordinates in our pipe are prescribed
by a given small curvature with finite range, while the pipe's cross section
being circular. Based on the straight pipe case a perturbative analysis by
which the boundary value conditions are exactly satisfied is employed. As such
an analysis we decompose the wave equation into a set of ordinary differential
equations perturbatively. We show the conditions when secular terms due to the
curbed boundary appear in the naive peturbative analysis. In eliminating such a
secularity with a singular perturbation method, we derive amplitude equations
and show that the eigenfrequencies in time are shifted due to the curved
boundary.

The fraction of stars which are in binaries or triples at the time of stellar
death and the fraction of these systems which survive the supernova (SN)
explosion are crucial constraints for evolution models and predictions for
gravitational wave source populations. These fractions are also subject to
direct observational determination. Here we search 10 supernova remnants (SNR)
containing compact objects with proper motions for unbound binaries or triples
using Gaia EDR3 and new statistical methods and tests for false positives. We
confirm the one known example of an unbound binary, HD 37424 in G180.0-01.7,
and find no other examples. Combining this with our previous searches for bound
and unbound binaries, and assuming no bias in favor of finding interacting
binaries, we find that 72.0% (52.2%-86.4%, 90% confidence) of SN producing
neutron stars are not binaries at the time of explosion, 13.9% (5.4%-27.2%)
produce bound binaries and 12.5% (2.8%-31.3%) produce unbound binaries. With a
strong bias in favor of finding interacting binaries, the medians shift to
76.0% were not binaries at death, 9.5% leave bound and 13.2% leave unbound
binaries. Of explosions that do not leave binaries, <18.9% can be fully unbound
triples. These limits are conservatively for M>5Msun stars, although the mass
limits for individual systems are significantly stronger. At birth, the
progenitor of PSR J0538+2817 was probably a 13-19Msun star, and at the time of
explosion it was probably a Roche limited, partially stripped star transferring
mass to HD 37424 and then producing a Type IIL or IIb supernova.

By using this formalism we could predict averages of cognitive observables.
Reflecting the basic idea of neurophisiological and psychological studies on a

a mathematical model of a mental space. We also briefly discuss the general
problem of the choice of adequate mental geometry.

We propose that by exciting ultra cold atoms from the zeroth to the first
Bloch band in an optical lattice, novel multi-flavor bosonic Hubbard
Hamiltonians can be realized in a new way. In these systems, each flavor hops
in a separate direction and on-site exchange terms allow pairwise conversion
between different flavors. Using band structure calculations, we determine the
parameters entering these Hamiltonians and derive the mean field ground state
phase diagram for two effective Hamiltonians (2D, two-flavors and 3D, three
flavors). Further, we estimate the stability of atoms in the first band using
second order perturbation theory and find lifetimes that can be considerable
(10-100 times) longer than the relevant time scale associated with inter-site
hopping dynamics, suggesting that quasi-equilibrium can be achieved in these
meta-stable states.

We discuss the main factors affecting the design of accelerators aiming to
investigate physics at the GUT scale. The most important constraints turn out
to be the energy used and the time taken to accumulate sufficient luminosity.
We propose a photon collider design, where the photons are generated by
undulator radiation from high energy muon beams. This reduces the energy
requirements by a factor of more than $10^7$ compared to a pp collider. Much of
the reduction in energy use is achieved by using a periodic magnetic field, and
by splitting the muon wavefunctions spatially to reduce the photon beam
divergence; these prevent a cascade of secondary reactions at the collision
points. The proposed collider would be powered by (part of) a Dyson swarm
constructed around the Sun, and efficient use of energy will be important to
reduce the time needed to reach the desired number of collisions. We also
discuss why a neutrino collider would be much less efficient.

The gelation of water suspension of a synthetic clay (Laponite) has been
studied by dynamic light scattering in a wide range of clay weight
concentration (Cw = 0.003-0.031). At variance with previous determination,
indicating a stable liquid phase for Cw < Cw*=0.015-0.018, we find that the
gelation takes actually place in the whole examined Cw range. More importantly,
we find that Cw* marks the transition between two different routes to gelation.
We hypothesize that at low concentration Laponite suspension behaves as an
attractive colloid and that the slowing down of the dynamics is attained by the
formation of larger and larger clusters while at high concentration the basic
units of the gel could be the Debye Huckel spheres associated to single
Laponite plates.

The interaction between substitutional nitrogen atoms in graphene is studied
by performing first principles calculations. The nearest neighbor interaction
between nitrogen dopants is highly repulsive because of the strong
electrostatic repulsion between nitrogen atoms, which prevents the full phase
separation in nitrogen doped graphene. Interestingly, there are two relatively
stable nitrogen-nitrogen pairs due to the anisotropy charge redistribution
induced by nitrogen doping. We reveal two stable semiconducting ordered N doped
graphene structures C3N and C12N through the cluster expansion technique and
particle swarm optimization method. In particular, C12N has a direct band gap
of 0.98 eV. The heterojunctions between C12N and graphene nanoribbons might be
promising organic solar cells.

The CDF preliminary analysis on polarized charmonium production at moderate
transverse momentum, $p_T \sim 4 - 20$ GeV, severely challenges the color octet
model (COM), which predicts quarkonium to be transversely polarized with
increasing $p_T$. Based on this data, we analyze the compatibility of the
Tevatron and the photoproduction at HERA in the context of the COM. Due to the
uncertainty on the extraction of non-relativistic QCD (NRQCD) matrix elements
and a lack of complete next-to-leading order calculations, one cannot
completely rule out the COM. Nonetheless, both collider experiments seem to
push the input matrix elements to opposite directions, and the puzzle of
quarkonium polarization remains unsolved.

A common approach to study nucleation rates is the estimation of free-energy
barriers. This usually requires knowledge about the shape of the forming
droplet, a task that becomes notoriously difficult in macromolecular setups
starting with a proper definition of the cluster boundary. Here, we demonstrate
a shape-free determination of the free energy for temperature-driven cluster
formation in particle as well as polymer systems. Combined with rigorous
results on equilibrium droplet formation, this allows for a well-defined
finite-size scaling analysis of the effective interfacial free energy at fixed
density. We first verify the theoretical predictions for the formation of a
liquid droplet in a supersaturated particle gas by generalized-ensemble Monte
Carlo simulations of a Lennard-Jones system. Going one step further, we then
generalize this approach to cluster formation in a dilute polymer solution. Our
results suggest an analogy with particle condensation, when the macromolecules
are interpreted as extended particles.

Developer forums contain opinions and information related to the usage of

official resources. Automatic linking of an API mention to its official
resources can be challenging for various reasons, such as, name overloading. We
present a technique, ANACE, to automatically resolve API mentions in the
textual contents of forum posts. Given a database of APIs, we first detect all
words in a forum post that are potential references to an API. We then use a
combination of heuristics and machine learning to eliminate false positives and
to link true positives to the actual APIs and their resources.

This paper considers the problem of channel coding with a given (possibly
suboptimal) maximum-metric decoding rule. A cost-constrained random-coding
ensemble with multiple auxiliary costs is introduced, and is shown to achieve
error exponents and second-order coding rates matching those of
constant-composition random coding, while being directly applicable to channels
with infinite or continuous alphabets. The number of auxiliary costs required
to match the error exponents and second-order rates of constant-composition
coding is studied, and is shown to be at most two. For i.i.d. random coding,
asymptotic estimates of two well-known non-asymptotic bounds are given using
saddlepoint approximations. Each expression is shown to characterize the
asymptotic behavior of the corresponding random-coding bound at both fixed and
varying rates, thus unifying the regimes characterized by error exponents,
second-order rates and moderate deviations. For fixed rates, novel exact
asymptotics expressions are obtained to within a multiplicative 1+o(1) term.
Using numerical examples, it is shown that the saddlepoint approximations are
highly accurate even at short block lengths.

Notwithstanding the usefulness of system dynamics in analyzing complex policy
problems, policy design is far from straightforward and in many instances
trial-and-error driven. To address this challenge, we propose to combine system
dynamics with network controllability, an emerging field in network science, to
facilitate the detection of effective leverage points in system dynamics models
and thus to support the design of influential policies. We illustrate our
approach by analyzing a classic system dynamics model: the World Dynamics
model. We show that it is enough to control only 53% of the variables to steer
the entire system to an arbitrary final state. We further rank all variables
according to their importance in controlling the system and we validate our
approach by showing that high ranked variables have a significantly larger
impact on the system behavior compared to low ranked variables.

The effect of a microwave field in the frequency range from 54 to 140
$\mathrm{GHz}$ on the magnetotransport in a GaAs quantum well with AlAs/GaAs
superlattice barriers and with an electron mobility no higher than $10^6$
$\mathrm{cm^2/Vs}$ is investigated. In the given two-dimensional system under
the effect of microwave radiation, giant resistance oscillations are observed
with their positions in magnetic field being determined by the ratio of the
radiation frequency to the cyclotron frequency. Earlier, such oscillations had
only been observed in GaAs/AlGaAs heterostructures with much higher mobilities.
When the samples under study are irradiated with a 140-$\mathrm{GHz}$ microwave
field, the resistance corresponding to the main oscillation minimum, which
occurs near the cyclotron resonance, appears to be close to zero. The results
of the study suggest that a mobility value lower than $10^6$ $\mathrm{cm^2/Vs}$
does not prevent the formation of zero-resistance states in magnetic field in a
two-dimensional system under the effect of microwave radiation.

The atomic surface and interface structure of bare and metal-coated ZnO(0001)
Zn-polar wafers were investigated via surface x-ray diffraction. All bare
samples showed the presence of a (1x1) overlayer of oxygen atoms located at the
on-top position above the terminating Zn atom, a structure predicted to be
unstable by several density functional theory calculations. The same oxygen
overlayer is clearly seen at the interface of ZnO with both elemental and
oxidized metal contact layers. No significant atomic relaxations are observed
at surfaces and interfaces processed under typical device fabrication
conditions.

Reconstructing Actions To Explain Deep Reinforcement Learning

|
Feature attribution has been a foundational building block for explaining the
input feature importance in supervised learning with Deep Neural Network
(DNNs), but face new challenges when applied to deep Reinforcement Learning
(RL).We propose a new approach to explaining deep RL actions by defining a
class of \emph{action reconstruction} functions that mimic the behavior of a
network in deep RL. This approach allows us to answer more complex
explainability questions than direct application of DNN attribution methods,
which we adapt to \emph{behavior-level attributions} in building our action
reconstructions. It also allows us to define \emph{agreement}, a metric for
quantitatively evaluating the explainability of our methods. Our experiments on
a variety of Atari games suggest that perturbation-based attribution methods
are significantly more suitable in reconstructing actions to explain the deep
RL agent than alternative attribution methods, and show greater
\emph{agreement} than existing explainability work utilizing attention. We
further show that action reconstruction allows us to demonstrate how a deep
agent learns to play Pac-Man game.

Knowledge Squeezed Adversarial Network Compression
| null | null | null | null |
cs.LG stat.ML
|
http://arxiv.org/licenses/nonexclusive-distrib/1.0/
|
Deep network compression has been achieved notable progress via knowledge
distillation, where a teacher-student learning manner is adopted by using
predetermined loss. Recently, more focuses have been transferred to employ the
adversarial training to minimize the discrepancy between distributions of
output from two networks. However, they always emphasize on result-oriented
learning while neglecting the scheme of process-oriented learning, leading to
the loss of rich information contained in the whole network pipeline. Inspired
by the assumption that, the small network can not perfectly mimic a large one
due to the huge gap of network scale, we propose a knowledge transfer method,
involving effective intermediate supervision, under the adversarial training
framework to learn the student network. To achieve powerful but highly compact
intermediate information representation, the squeezed knowledge is realized by
task-driven attention mechanism. Then, the transferred knowledge from teacher
network could accommodate the size of student network. As a result, the
proposed method integrates merits from both process-oriented and
result-oriented learning. Extensive experimental results on three typical
benchmark datasets, i.e., CIFAR-10, CIFAR-100, and ImageNet, demonstrate that
our method achieves highly superior performances against other state-of-the-art
methods.

We report the discovery of a remarkable gamma-ray transient source near the
Galactic plane, GRO J1838-04. This source was serendipitously discovered by
EGRET in June 1995 with a peak intensity of 4 E(-6) ph/cm/cm/s (for photon
energies larger than 100 MeV) and a 5.9 sigma significance. At that time, GRO
J1838-04 was the second brightest gamma-ray source in the sky. A subsequent
EGRET pointing in late September 1995 detected the source at a flux smaller
than its peak value by a factor of 7. We determined that no radio-loud
spectrally-flat blazar is within the error box of GRO J1838-04. We discuss the
origin of the \ggg-ray transient source and show that interpretations in terms
of AGNs or isolated pulsars are highly problematic. GRO J1838-04 provides
strong evidence for the existence of a new class of variable gamma-ray sources.

We address the problem of possible deformations of exactly solvable
potentials having finitely many discrete eigenvalues of arbitrary choice. As
Kay and Moses showed in 1956, reflectionless potentials in one dimensional
quantum mechanics are exactly solvable. With an additional time dependence
these potentials are identified as the soliton solutions of the KdV hierarchy.
An $N$-soliton potential has the time $t$ and $2N$ positive parameters,
$k_1<...<k_N$ and $c_j$, $j=1,...,N$, corresponding to $N$ discrete eigenvalues
$-k_j^2$. The eigenfunctions are elementary functions expressed by the ratio of
determinants. The Darboux-Crum-Krein-Adler transformation or the Abraham-Moses
transformations based on eigenfunctions deletions produce lower soliton number
potentials with modified parameters $c'_j$. We explore various identities
satisfied by the eigenfunctions of the soliton potentials, which reflect the
uniqueness theorem of Gel'fand-Levitan-Marchenko equations for separable
(degenerate) kernels.

Non-linear Nyquist theorem: A conjecture

Thermodynamics of equilibrium states is well established. However, in
nonequilibrium few general results are known. One prime and important example
is that of Nyquist theorem. It relates equilibrium tiny voltage fluctuations
across a conductor with its resistance. In linear systems it was proved in its
generality in a beautiful piece of work by Callen and Welton (in
1950s\cite{cw}). However Callen-Welton's formalism has not been extended to
nonlinear systems up to now, although alternative methods exist (like Kubo's
approach) that leads to formal and implicit expressions {\it at nonlinear
order} with no practical consequence. Here--using a brute-force method--we
conjecture "a non-linear Nyquist theorem". This is an explicit formula much
like Nyquist's original one. Our conjecture is based upon tests of the
conjectured explicit formula in specific systems. We conjecture that higher
moments of {\it equilibrium} fluctuations bear a relation to {\it nonlinear}
admittance very similar to Nyquist's relation. Thus one can easily compute
nonlinear admittance from the character of {\it equilibrium} fluctuations. Our
relation will have great practical applicability, for example for electronic
devices that operate under nonlinear response.

A simultaneous input and state interval observer is presented for Lipschitz
continuous nonlinear systems with unknown inputs and bounded noise signals for
the case when the direct feedthrough matrix has full column rank. The observer
leverages the existence of bounding decomposition functions for mixed monotone
mappings to recursively compute the maximal and minimal elements of the
estimate intervals that are compatible with output/measurement signals, and are
proven to contain the true state and unknown input. Furthermore, we derive a
Lipschitz-like property for decomposition functions, which provides several
sufficient conditions for stability of the designed observer and boundedness of
the sequence of estimate interval widths. Finally, the effectiveness of our
approach is demonstrated using an illustrative example.

We report trace element analyses by laser ablation inductively coupled plasma
mass spectrometry of metal grains from 9 different CR chondrites,
distinguishing grains from chondrule interior ("interior grains"), chondrule
surficial shells ("margin grains") and the matrix ("isolated grains"). Save for
a few anomalous grains, Ni-normalized trace element patterns are similar for
all three petrographical settings, with largely unfractionated refractory
siderophile elements and depleted volatile Au, Cu, Ag, S. All types of grains
are interpreted to derive from a common precursor approximated by the least
melted, fine-grained objects in CR chondrites. This also excludes
recondensation of metal vapor as the origin of the bulk of margin grains. The
metal precursors presumably formed by incomplete condensation, with evidence
for high-temperature isolation of refractory platinum-group-element (PGE)-rich
condensates before mixing with lower temperature PGE-depleted condensates. The
rounded shape of the Ni-rich, interior grains indicates melting and
equilibration with silicates upon slow cooling (1-100 K/h), largely by
oxidation/evaporation of Fe. We propose that Ni-poorer, amoeboid margin grains,
often included in the pyroxene-rich periphery common to type I chondrules,
result from less intense processing of a rim accreted onto the chondrule
subsequent to the melting event recorded by the interior. This means either
that there were two separate heating events, which formed olivine/interior
grains and pyroxene/margin grains, respectively, between which dust was
accreted around the chondrule, or there was a single high-temperature event, of
which the chondrule margin record a late "quenching phase", in which case dust
accreted onto chondrules while they were molten. In the latter case, high dust
concentrations in the chondrule-forming region are indicated.

High energy cosmic ray electrons plus positrons (CREs), which lose energy
quickly during their propagation, provide an ideal probe of Galactic
high-energy processes and may enable the observation of phenomena such as
dark-matter particle annihilation or decay. The CRE spectrum has been directly
measured up to $\sim 2$ TeV in previous balloon- or space-borne experiments,
and indirectly up to $\sim 5$ TeV by ground-based Cherenkov $\gamma$-ray
telescope arrays. Evidence for a spectral break in the TeV energy range has
been provided by indirect measurements of H.E.S.S., although the results were
qualified by sizeable systematic uncertainties. Here we report a direct
measurement of CREs in the energy range $25~{\rm GeV}-4.6~{\rm TeV}$ by the
DArk Matter Particle Explorer (DAMPE) with unprecedentedly high energy
resolution and low background. The majority of the spectrum can be properly
fitted by a smoothly broken power-law model rather than a single power-law
model. The direct detection of a spectral break at $E \sim0.9$ TeV confirms the
evidence found by H.E.S.S., clarifies the behavior of the CRE spectrum at
energies above 1 TeV and sheds light on the physical origin of the sub-TeV
CREs.

We give numerically tractable, explicit integral expressions for the
distribution of the signal-to-interference-and-noise-ratio (SINR) experienced
by a typical user in the down-link channel from the k-th strongest base
stations of a cellular network modelled by Poisson point process on the plane.
Our signal propagation-loss model comprises of a power-law path-loss function
with arbitrarily distributed shadowing, independent across all base stations,
with and without Rayleigh fading. Our results are valid in the whole domain of
SINR, in particular for SINR<1, where one observes multiple coverage. In this
latter aspect our paper complements previous studies reported in [Dhillon et
al. JSAC 2012].

Lattice measurements of spatial correlation functions of the operators FF and
FF-dual in thermal SU(3) gauge theory have revealed a clear difference between
the two channels at "intermediate" distances, x ~ 1/(pi T). This is at odds
with the AdS/CFT limit which predicts the results to coincide. On the other
hand, an OPE analysis at short distances (x << 1/(pi T)) as well as effective
theory methods at long distances (x >> 1/(pi T)) suggest differences. Here we
study the situation at intermediate distances by determining the time-averaged
spatial correlators through a 2-loop computation. We do find unequal results,
however the numerical disparity is small. Apart from theoretical issues, a
future comparison of our results with time-averaged lattice measurements might
also be of phenomenological interest in that understanding the convergence of
the weak-coupling series at intermediate distances may bear on studies of the
thermal broadening of heavy quarkonium resonances.

We introduce a novel technique, called "granulometry", to characterize and
recover the mean size and the size distribution of HII regions from 21-cm
tomography. The technique is easy to implement, but places the previously not
very well defined concept of morphology on a firm mathematical foundation. The
size distribution of the cold spots in 21-cm tomography can be used as a direct
tracer of the underlying probability distribution of HII region sizes. We
explore the capability of the method using large-scale reionization simulations
and mock observational data cubes while considering capabilities of SKA1-low
and a future extension to SKA2. We show that the technique allows the recovery
of the HII region size distribution with a moderate signal-to-noise ratio from
wide-field imaging ($\rm SNR\lesssim3$), for which the statistical uncertainty
is sample variance dominated. We address the observational requirements on the
angular resolution, the field-of-view, and the thermal noise limit for a
successful measurement. To achieve a full scientific return from 21-cm
tomography and to exploit a synergy with 21-cm power spectra, we suggest an
observing strategy using wide-field imaging (several tens of square degrees) by
an interferometric mosaicking/multi-beam observation with additional
intermediate baselines (~2-4 km).

Semi-inclusive deep inelastic Scattering (SIDIS) has been a very successful
tool to investigate the partonic structure of the nucleon over the last decade.
Compared to inclusive DIS, information about the quantum numbers of the struck
quark can be inferred from the identity, distribution and polarization of the
final state hadrons. Up to now, virtually all knowledge about the quark-gluon
structure of the nucleon from SIDIS has been gained from distributions of
independently observed scalar hadrons. However, given the amount of data
current and future experiments at JLab, RHIC, KEK and the EIC will collect, new
paradigms have to be explored to leverage the statistical power of the data.
Similar to other felds in nuclear and particle physics, it is natural to move
towards the exploration of more complex correlations in the observed fi nal
state. This contribution will discuss recent results and future prospects of
using di-hadron correlations and polarized hyperon probes to study QCD in
SIDIS, pp and e+e- annihilation. Both of these probes exploit additional
degrees of freedom in the final state, given by the relative momentum of the
di-hadron pair and the hyperon polarization, respectively. This contribution
will focus on recent results and opportunities opened by these probes to study
nucleon structure, hadronization and QCD in novel ways. The focus will be on
planned SIDIS measurements at CLAS12 at JLab and e+e- at Belle II.

Threshold secret sharing schemes do not prevent any malicious behavior of the
dealer or shareholders and so we need verifiable secret sharing, to detect and
identify the cheaters, to achieve fair reconstruction of a secret. The problem
of verifiable secret sharing is to verify the shares distributed by the dealer.
A novel approach for verifiable secret sharing is presented in this paper where
both the dealer and shareholders are not assumed to be honest. In this paper,
we extend the term verifiable secret sharing to verify the shares, distributed
by a dealer as well as shares submitted by shareholders for secret
reconstruction, and to verify the reconstructed secret. Our proposed scheme
uses a one way hash function and probabilistic homomorphic encryption function
to provide verifiability and fair reconstruction of a secret.

Representation learning models for graphs are a successful family of
techniques that project nodes into feature spaces that can be exploited by
other machine learning algorithms. Since many real-world networks are
inherently dynamic, with interactions among nodes changing over time, these
techniques can be defined both for static and for time-varying graphs. Here, we
build upon the fact that the skip-gram embedding approach implicitly performs a
matrix factorization, and we extend it to perform implicit tensor factorization
on different tensor representations of time-varying graphs. We show that
higher-order skip-gram with negative sampling (HOSGNS) is able to disentangle
the role of nodes and time, with a small fraction of the number of parameters
needed by other approaches. We empirically evaluate our approach using
time-resolved face-to-face proximity data, showing that the learned
time-varying graph representations outperform state-of-the-art methods when
used to solve downstream tasks such as network reconstruction, and to predict
the outcome of dynamical processes such as disease spreading. The source code
and data are publicly available at https://github.com/simonepiaggesi/hosgns.

uncertainty relation are constructed as eigenstates of a linear combination of
Weyl generators of the $su(3)$ algebra. The construction is based on the

We prove a "height-free" effective isogeny estimate for abelian varieties of
$\mathrm{GL}_2$-type.
More precisely, let $g\in \mathbb{Z}^+$, $K$ a number field, $S$ a finite set
of places of $K$, and $A,B/K$ $g$-dimensional abelian varieties with good
reduction outside $S$ which are $K$-isogenous and of $\mathrm{GL}_2$-type over
$\overline{\mathbb{Q}}$. We show that there is a $K$-isogeny $A\to B$ of degree
effectively bounded in terms of $g$, $K$, and $S$ only.
We deduce among other things an effective upper bound on the number of
$S$-integral $K$-points on a Hilbert modular variety.

We study magnetic phases of two-component mixtures of ultracold fermions with
repulsive interactions in optical lattices in the presence of hopping
imbalance. Our analysis is based on dynamical mean-field theory (DMFT) and its
real-space generalization at finite temperature. We study the temperature
dependence of the transition into the ordered state as a function of the
interaction strength and the imbalance parameter in two and three spatial
dimensions. We show that below the critical temperature for N\'{e}el order
mass-imbalanced mixtures also exhibit a charge-density wave, which provides a
directly observable signature of the ordered state. For the trapped system, we
compare our results obtained by real-space DMFT to a local-density
approximation. We calculate the entropy for a wide range of parameters and
identify regions, in which mass-imbalanced mixtures could have clear advantages
over balanced ones for the purpose of obtaining and detecting quantum
magnetism.

We present the first results of the search of new halo and relic candidates
in the NRAO VLA Sky Survey. We have inspected a sample of 205 clusters from the
X-ray-brightest Abell-type clusters presented by Ebeling et al (1996), and
found 29 candidates. Out of them, 11 clusters are already known from the
literature to contain a diffuse cluster-wide source, while in 18 clusters this
is the first indication of the existence of this type of sources. We classify
these sources as halos or relics according to their location in the cluster
center or periphery, respectively. We find that the occurrence of cluster halos

In crystal growth, surfactants are additive molecules used in dilute amount
or as dense, permeable layers to control surface morphologies. Here, we
investigate the properties of a strikingly different surfactant: a
two-dimensional and covalent layer with close atomic packing, graphene. Using
in situ, real time electron microscopy, scanning tunneling microscopy, kinetic
Monte Carlo simulations, and continuum mechanics calculations, we reveal why
metallic atomic layers can grow in a two-dimensional manner below an
impermeable graphene membrane. Upon metal growth, graphene dynamically opens
nanochannels called wrinkles, facilitating mass transport, while at the same
time storing and releasing elastic energy via lattice distortions. Graphene
thus behaves as a mechanically active, deformable surfactant. The
wrinkle-driven mass transport of the metallic layer intercalated between
graphene and the substrate is observed for two graphene-based systems,
characterized by different physico-chemical interactions, between graphene and
the substrate, and between the intercalated material and graphene. The
deformable surfactant character of graphene that we unveil should then apply to
a broad variety of species, opening new avenues for using graphene as a
two-dimensional surfactant forcing the growth of flat films, nanostructures and
unconventional crystalline phases.

By carrying out density functional theory analysis within the Keldysh
non-equilibrium Green's functional formalism, we have calculated the nonlinear
and non-equilibrium quantum transport properties of Fe/MgO/Fe trilayer
structures as a function of external bias voltage. For well relaxed atomic
structures of the trilayer, the equilibrium tunnel magnetoresistance ratio
(TMR) is found to be very large and also fairly stable against small variations
in the atomic structure. As a function of external bias voltage, the TMR
reduces monotonically to zero with a voltage scale of about 1V, in agreement
with experimental observations. We present understanding of the nonequilibrium
transport properties by investigating microscopic details of the scattering
states and the Bloch bands of the Fe leads.

We report the detection of a third HI 21-cm absorber in the sight-line
towards the z=2.64 quasar MG J0414+0534 (4C +05.19). In addition to the
absorption at the host redshift and in the z=0.96 gravitational lens, we find,
through a decimetre-wave spectral scan towards this source, strong absorption
at z=0.38. We believe this may be associated with "Object X", an additional
feature apparent in the field of the lensing galaxy and lensed images, on the
basis of its close proximity to the quasar images and the possible detection of
the [OIII] doublet in a published optical spectrum. If real, the strength of
the [OIII] emission would suggest the presence of an active galactic nucleus,
or a gas-rich galaxy undergoing rapid star formation, either of which is
consistent with the strong outflows apparent in the 21-cm spectrum. Although
this is the strongest intervening 21-cm absorber yet found, simultaneous
observations failed to detect any of the 18-cm OH lines at the 21-cm redshift.
This suggests that, as for the lensing galaxy, this is not the primary location
of the intervening material responsible for the very red colour of MG
J0414+0534.

We propose an approach to construct Bernoulli trials $\{X_i, i\ge 1\}$
combining dependence and independence periods, and call it Bernoulli sequence
with random dependence (BSRD). The structure of dependence, on the past $S_i =
X_1 + \ldots + X_i$, {defines} a class of non-Markovian random walks of recent
interest in the literature. In this paper, the dependence is activated by an
auxiliary collection of Bernoulli trials $\{Y_i, i\ge 1\}$, called {\it memory
switch sequence}. We introduce the concept of {\it memory lapses property},
which {is} characterized by intervals of consecutive independent steps in BSRD.
The main results include classical limit theorems for a class of linear BSRD.
In particular, we obtain a central limit theorem for a class of BSRD which
generalizes some previous results in literature. Along the paper, several
examples of potential applications are provided.

We propose a secure transmission scheme for a relay wiretap channel, where a
source communicates with a destination via a decode-and-forward relay in the
presence of spatially random-distributed eavesdroppers. We assume that the
source is equipped with multiple antennas, whereas the relay, the destination,
and the eavesdroppers are equipped with a single antenna each. In the proposed
scheme, in addition to information signals, the source transmits artificial
noise signals in order to confuse the eavesdroppers. With the target of
maximizing the secrecy throughput of the relay wiretap channel, we derive a
closed-form expression for the transmission outage probability and an
easy-to-compute expression for the secrecy outage probability. Using these
expressions, we determine the optimal power allocation factor and wiretap code
rates that guarantee the maximum secrecy throughput, while satisfying a secrecy
outage probability constraint. Furthermore, we examine the impact of source
antenna number on the secrecy throughput, showing that adding extra transmit
antennas at the source brings about a significant increase in the secrecy
throughput.

We study the interaction and dynamics of two half-quantized vortices in
two-component Bose- Einstein condensates. Using the Pade approximation for the
vortex core profile, we calculate the intervortex potential, whose asymptotic
form for a large distance has been derived by Eto et al. [Phys. Rev. A, 83,
063603 (2011)]. Through numerical simulations of the two-dimensional
Gross-Pitaevskii equations, we reveal different kinds of dynamical trajectories
of the vortices depending on the combinations of signs of circulations and the
intercomponent density coupling. Under the adiabatic limit, we derive the
equations of motion for the vortex coordinates, in which the motion is caused
by the balance between Magnus force and the intervortex forces. The initial
velocity of the vortex motion can be explained quantitatively by this point
vortex approximation, but under- standing the long-time behavior of the
dynamics needs more consideration beyond our model.

I present a unified discussion of several recently published results
concerning the escalation, timing and severity of violent events in human
conflicts and global terrorism, and set them in the wider context of real-world
and cyber-based collective violence and illicit activity. I point out how the
borders distinguishing between such activities are becoming increasingly
blurred in practice -- from insurgency, terrorism, criminal gangs and
cyberwars, through to the 2011 Arab Spring uprisings and London riots. I review
the robust empirical patterns that have been found, and summarize a minimal
mechanistic model which can explain these patterns. I also explain why this
mechanistic approach, which is inspired by non-equilibrium statistical physics,
fits naturally within the framework of recent ideas within the social science
literature concerning analytical sociology. In passing, I flag the fundamental
flaws in each of the recent critiques which have surfaced concerning the
robustness of these results and the realism of the underlying model mechanisms.

We argue the sign problem of the fermion determinant at finite density. It is
unavoidable not only in Monte-Carlo simulations on the lattice but in the
mean-field approximation as well. A simple model deriving from Quantum
Chromodynamics (QCD) in the double limit of large quark mass and large quark
chemical potential exemplifies how the sign problem arises in the Polyakov loop
dynamics at finite temperature and density. In the color SU(2) case our
mean-field estimate is in excellent agreement with the lattice simulation. We
combine the mean-field approximation with a simple phase reweighting technique
to circumvent the complex action encountered in the color SU(3) case. We also
investigate the mean-field free energy, from the saddle-point of which we can
estimate the expectation value of the Polyakov loop.

$B_{1g}$ and B$_{2g}$ channels in the superconducting state of Hg-1201
advocates for a gap having d-wave symmetry. In addition a resonant study
$B_{1g}$ pair-breaking peak and the $A_{1g}$ peak suggests that the $A_{1g}$
peak is not directly related to the d-wave superconducting gap amplitude.
Comparison with trilayer Hg-1223 demonstrates the universal behavior of this

A host of elastic systems consisting of active components exhibit
path-dependent elastic behaviors not found in classical elasticity, which is
known as odd elasticity. Odd elasticity is characterized by antisymmetric (odd)
elastic modulus tensor. Here, from the perspective of geometry, we construct
the Hamiltonian formalism to show the origin of the antisymmetry of the elastic
moduli. Furthermore, both non-conservative stress and the associated nonlinear
constitutive relation naturally arise. This work also opens the promising
possibility of exploring the physics of odd elasticity in dynamical regime by
Hamiltonian formalism.

We report high angular-resolution (~1") CO J=3--2 interferometric mapping,
using the Submillimeter Array (SMA), of IRAS22036+5306 (I22036), a bipolar
pre-planetary nebula (PPN) with knotty jets discovered in our HST SNAPshot
survey of young PPNs. In addition, we have obtained supporting lower-resolution
(~10") CO and 13CO J=1-0 observations with the Owens Valley Radio Observatory
(OVRO) interferometer, as well as optical long-slit echelle spectra at the
Palomar Observatory. The CO J=3-2 observations show the presence of a very fast
(~220 km/s), highly collimated, massive (0.03 Msun) bipolar outflow with a very
large scalar momentum (about 10^{39} g cm s^{-1}), and the characteristic
spatio-kinematic structure of bow-shocks at the tips of this outflow. The
Halpha line shows an absorption feature blue-shifted from the systemic velocity
by ~100 km/s, which most likely arises in neutral interface material between
the fast outflow and the dense walls of the bipolar lobes at low latitudes. The
fast outflow in I22036, as in most PPNs, cannot be driven by radiation
pressure. We find an unresolved source of submillimeter (and millimeter-wave)
continuum emission in I22036, implying a very substantial mass (0.02-0.04 Msun)
of large (radius >~1 mm), cold (< ~50 K) dust grains associated with I22036's
toroidal waist. We also find that the 13C/12C ratio in I22036 is very high
(0.16), close to the maximum value achieved in equilibrium CNO-nucleosynthesis
(0.33). The combination of the high circumstellar mass (i.e., in the extended
dust shell and the torus) and the high 13C/12C ratio in I22036 provides strong
support for this object having evolved from a massive (>~4 Msun) progenitor in
which hot-bottom-burning has occurred.

Critical properties of a geometrically frustrated generalized $XY$ model with
antiferromagnetic (AFM) and third-order antinematic (AN3) couplings on a
triangular lattice are studied by Monte Carlo simulation. It is found that such
a generalization leads to a phase diagram consisting of three different
quasi-long-range ordered (QLRO) phases. Compared to the model with the
second-order antinematic (AN2) coupling, besides the AFM and AN3 phases which
appear in the limits of relatively strong AFM and AN3 interactions,
respectively, it includes an additional complex canted antiferromagnetic (CAFM)
phase. It emerges at lower temperatures, wedged between the AFM and AN3 phases,
as a result of the competition between the AFM and AN3 couplings, which is
absent in the model with the AN2 coupling. The AFM-CAFM and AN3-CAFM phase
transitions are concluded to belong to the weak Ising and weak three-state
Potts universality classes, respectively. Additionally, all three QLRO phases
also feature true LRO of the standard and generalized chiralities, which both
vanish simultaneously at second-order phase transitions with non-Ising critical
exponents and the critical temperatures slightly higher than the magnetic and
nematic order-disorder transition temperatures.

We propose a model to describe a gas of pyramidal molecules interacting via
dipole-dipole interactions. The interaction modifies the tunneling properties
between the classical equilibrium configurations of the single molecule and,
for sufficiently high pressure, the molecules become localized in these
classical configurations. We explain quantitatively, without free parameters,
the shift to zero frequency of the inversion line observed upon increase of the
pressure in a gas of ammonia or deuterated ammonia. For sufficiently high
pressures, our model suggests the existence of a superselection rule for states
of different chirality in substituted derivatives.

three-dimensional particle-in-cell (PIC) simulations for the surface plasmon
excitation with the finite-difference time-domain method (FDTD). A
three-dimensional model for an electron bunch movement near the metal film is
constructed, and particle-in-cell (PIC) simulations are carried out with
various metal films of different thicknesses. The frequency of surface plasmon
obtained from PIC simulation is agreed with that from theory. Furthermore, the
surface plasmon wave properties of excitation and propagation with the metal
film is summarized by PIC results.

Artificial neural networks (ANNs), while exceptionally useful for
classification, are vulnerable to misdirection. Small amounts of noise can
significantly affect their ability to correctly complete a task. Instead of
generalizing concepts, ANNs seem to focus on surface statistical regularities
in a given task. Here we compare how recurrent artificial neural networks, long
short-term memory units, and Markov Brains sense and remember their
environments. We show that information in Markov Brains is localized and
sparsely distributed, while the other neural network substrates "smear"
information about the environment across all nodes, which makes them vulnerable
to noise.

Let X be a data matrix of rank \rho, whose rows represent n points in
d-dimensional space. The linear support vector machine constructs a hyperplane
separator that maximizes the 1-norm soft margin. We develop a new oblivious
dimension reduction technique which is precomputed and can be applied to any
input matrix X. We prove that, with high probability, the margin and minimum
enclosing ball in the feature space are preserved to within \epsilon-relative
error, ensuring comparable generalization as in the original space in the case
of classification. For regression, we show that the margin is preserved to
\epsilon-relative error with high probability. We present extensive experiments
with real and synthetic data to support our theory.

Using numerical simulations we investigate the transverse depinning of moving
vortex lattices interacting with random disorder. We observe a finite
transverse depinning barrier for vortex lattices that are driven with high
longitudinal drives, when the vortex lattice is defect free and moving in
correlated 1D channels. The transverse barrier is reduced as the longitudinal
drive is decreased and defects appear in the vortex lattice, and the barrier
disappears in the plastic flow regime. At the transverse depinning transition,
the vortex lattice moves in a staircase pattern with a clear transverse
narrow-band voltage noise signature.

We investigate magnetic and charge correlations in graphene by using the
formulation of extended dynamical mean-field theory (E-DMFT) for two-sublattice
systems. First, we map the average non-local interaction onto the effective
static interaction between different sublattices, which is treated together
with the local interaction within an effective "two-orbital" local model. The
remaining part of the non-local interaction is considered by introducing an
effective retarded interaction within the E-DMFT approach. The non-local
susceptibilities in charge and spin channel are further evaluated in the ladder
approximation. We verify the applicability of the proposed method to describe
the effect of uniformly screened long-range Coulomb potential $\propto 1/r$, as
well as screened realistic long-range electron interaction [T. O. Wehling et
al., Phys. Rev. Lett. 106, 236805 (2011)] in graphene. We show that the
developed approach describes a competition of semimetal, spin density wave
(SDW), and charge-density-wave (CDW) correlations. The obtained phase diagram
is in a good agreement with recent results of functional renormalization group
(fRG) for finite large graphene nanoflakes and scaling analysis of quantum
Monte Carlo data on finite clusters. Similarly to the previously obtained
results within the fRG approach, the realistic screening of Coulomb interaction
by $\sigma$ bands causes moderate (strong) enhancement of critical long-range
interaction strength, needed for the SDW (CDW) instability, compared to the
results for the uniformly screened Coulomb potential.

Some of the important inequalities associated with quantum entropy are
immediate algebraic consequences of the Hansen-Pedersen-Jensen inequality. A
general argument is given in terms of the matrix perspective of an operator
convex function. A matrix analogue of Mar\'{e}chal's extended perspectives
provides additional inequalities, including a $p+q\leq 1$ result of Lieb.

We study a two-dimensional tight-binding lattice for excitons with on-site
disorder, coupled to a thermal environment at infinite temperature. The
disorder acts to localise an exciton spatially, while the environment generates
dynamics which enable exploration of the lattice. Although the steady state of
the system is trivially uniform, we observe a rich dynamics and uncover a
dynamical phase transition in the space of temporal trajectories. This
transition is identified as a localisation in the dynamics generated by the
bath. We explore spatial features in the dynamics and employ a generalisation
of the inverse participation ratio to deduce an ergodic timescale for the
lattice.

We describe the main features of our most recent Hartree-Fock-Bogoliubov
nuclear mass models, based on 16-parameter generalized Skyrme forces. They have
been fitted to the data of the 2012 Atomic Mass Evaluation, and favour a value
of 30 MeV for the symmetry coefficient J, the corresponding root-mean square
deviation being 0.549 MeV. We find that this conclusion is compatible with
measurements of neutron-skin thickness. By constraining the underlying
interactions to fit various equations of state of neutron matter calculated
{\it ab initio} our models are well adapted to a realistic and unified
treatment of all regions of neutron stars. We use our models to calculate the
composition, the equation of state, the mass-radius relation and the maximum
mass. Comparison with observations of neutron stars again favours a value of J
= 30 MeV.

Resilient Distributed Parameter Estimation with Heterogeneous Data

This paper studies resilient distributed estimation under measurement
attacks. A set of agents each makes successive local, linear, noisy
measurements of an unknown vector field collected in a vector parameter. The
local measurement models are heterogeneous across agents and may be locally
unobservable for the unknown parameter. An adversary compromises some of the
measurement streams and changes their values arbitrarily. The agents' goal is
to cooperate over a peer-to-peer communication network to process their
(possibly compromised) local measurements and estimate the value of the unknown
vector parameter. We present SAGE, the Saturating Adaptive Gain Estimator, a
distributed, recursive, consensus+innovations estimator that is resilient to
measurement attacks. We demonstrate that, as long as the number of compromised
measurement streams is below a particular bound, then, SAGE guarantees that all
of the agents' local estimates converge almost surely to the value of the
parameter. The resilience of the estimator -- i.e., the number of compromised
measurement streams it can tolerate -- does not depend on the topology of the
inter-agent communication network. Finally, we illustrate the performance of
SAGE through numerical examples.

series for products of maps. The behaviour under products of the radius of
convergence for the zeta function, and the abscissa of convergence for the
orbit Dirichlet series, are discussed. The orbit Dirichlet series of the
cartesian cube of a map with one orbit of each length is shown to have a
natural boundary.

Underwater Stereo using Refraction-free Image Synthesized from Light

There is a strong demand on capturing underwater scenes without distortions
caused by refraction. Since a light field camera can capture several light rays
at each point of an image plane from various directions, if geometrically
correct rays are chosen, it is possible to synthesize a refraction-free image.
In this paper, we propose a novel technique to efficiently select such rays to
synthesize a refraction-free image from an underwater image captured by a light
field camera. In addition, we propose a stereo technique to reconstruct 3D
shapes using a pair of our refraction-free images, which are central
projection. In the experiment, we captured several underwater scenes by two
light field cameras, synthesized refraction free images and applied stereo
technique to reconstruct 3D shapes. The results are compared with previous
techniques which are based on approximation, showing the strength of our
method.
