Despite providing similar functionality, multiple network services may
require the use of different interfaces to access the functionality, and this
problem will only get worse with the widespread deployment of ubiquitous
computing environments. One way around this problem is to use interface
adapters that adapt one interface into another. Chaining these adapters allows
flexible interface adaptation with fewer adapters, but the loss incurred due to
imperfect interface adaptation must be considered. This paper outlines a
mathematical basis for analyzing the chaining of lossy interface adapters. We
also show that the problem of finding an optimal interface adapter chain is
NP-complete.

We present a comment on the kinematic variable $m_{CT2}$ recently proposed in
"Amplification of endpoint structure for new particle mass measurement at the
LHC". The variable is designed to be applied to models such as R-parity
conserving Supersymmetry (SUSY) when there is pair production of new heavy
particles each of which decays to a single massless visible and a massive
invisible component. It was proposed in "Amplification of endpoint structure
for new particle mass measurement at the LHC" that a measurement of the peak of
the $m_{CT2}$ distribution could be used to precisely constrain the masses of
the SUSY particles. We show that when Standard Model backgrounds are included
in simulations, the sensitivity of the $m_{CT2}$ variable to the SUSY particle
masses is more seriously impacted for $m_{CT2}$ than for other previously
proposed variables.

We present an alternative scenario for cosmic structure formation where
initial fluctuations are due to Kalb-Ramond axions produced during a pre-big
bang phase of inflation. We investigate whether this scenario, where the
fluctuations are induced by seeds and therefore are of isocurvature nature, can
be brought in agreement with present observations by a suitable choice of
cosmological parameters. We also discuss several observational signatures which
can distinguish axion seeds from standard inflationary models.

We re-examine the three-dimensional spinless Falicov-Kimball model with
dispersive $f$ electrons at half-filling, addressing the dispute about the
formation of an excitonic condensate, which is closely related to the problem
of electronic ferroelectricity. To this end, we work out a slave-boson
functional integral representation of the suchlike extended Falicov-Kimball
model that preserves the $SO(2)\otimes U(1)^{\otimes 2}$ invariance of the
action. We find a spontaneous pairing of $c$ electrons with $f$ holes, building
an excitonic insulator state at low temperatures, also for the case of
initially non-degenerate orbitals. This is in contrast to recent predictions of
scalar slave-boson mean-field theory but corroborates previous Hartree-Fock and
RPA results. Our more precise treatment of correlation effects, however, leads
to a substantial reduction of the critical temperature. The different behavior
of the partial densities of states in the weak and strong inter-orbital Coulomb
interaction regimes supports a BCS-BEC transition scenario.

Online and stochastic learning has emerged as powerful tool in large scale
optimization. In this work, we generalize the Douglas-Rachford splitting (DRs)
method for minimizing composite functions to online and stochastic settings (to
our best knowledge this is the first time DRs been generalized to sequential
version). We first establish an $O(1/\sqrt{T})$ regret bound for batch DRs
method. Then we proved that the online DRs splitting method enjoy an $O(1)$
regret bound and stochastic DRs splitting has a convergence rate of
$O(1/\sqrt{T})$. The proof is simple and intuitive, and the results and
technique can be served as a initiate for the research on the large scale
machine learning employ the DRs method. Numerical experiments of the proposed
method demonstrate the effectiveness of the online and stochastic update rule,
and further confirm our regret and convergence analysis.

Differing reaction rates of long-lived nuclear states can force the level
occupations out of thermal equilibrium, causing calculations of overall rates
which rely on thermal equilibrium to be inaccurate. Therefore, nucleosynthesis
calculations which include nuclei with isomers must use techniques that do not
assume thermal equilibrium, and it is imperative that such techniques
appropriately account for transitions between the ground and isomeric states
via higher-lying levels. We develop a formalism to compute the steady state
occupations of nuclear levels and apply it to the examples 26Al, 34Cl, and
85Kr. We show that this approach is useful both for assessing the required
number of nuclear levels and for determining the temperature above which
thermal equilibrium rates are appropriate.

We proof here the existence of a topological thick and thin decomposition of
any closed definable thick isolated singularity germ in the spirit of the
recently discovered metric thick and thin decomposition of complex normal
surface singularities of [10]. Our thin zone catches exactly the homology of
the family of the links collapsing faster than linearly. Simultaneously we
introduce a class of rigid homeomorphisms more general than bi-Lipschitz ones,
which map the topological thin zone onto the topological thin zone of its
image. As a consequence of this point of view for the class of singularities we
consider we exhibit an equivalent description of the notion of separating sets
in terms of this fast contracting homology

We study the error induced by the time discretization of a decoupled
forward-backward stochastic differential equations $(X,Y,Z)$. The forward
component $X$ is the solution of a Brownian stochastic differential equation
and is approximated by a Euler scheme $X^N$ with $N$ time steps. The backward
component is approximated by a backward scheme. Firstly, we prove that the
errors $(Y^N-Y,Z^N-Z)$ measured in the strong $L\_p$-sense ($p \geq 1$) are of
order $N^{-1/2}$ (this generalizes the results by Zhang 2004). Secondly, an
error expansion is derived: surprisingly, the first term is proportional to
$X^N-X$ while residual terms are of order $N^{-1}$.

Improved Selective Harmonic Elimination for Reducing Torque Harmonics of
Induction Motors in Wide DC Bus Voltage Variations
| null | null | null | null |

http://arxiv.org/licenses/nonexclusive-distrib/1.0/
|
Conventionally, Selective Harmonic Elimination (SHE) method in 2-level
inverters, finds best switching angles to reach first voltage harmonic to
reference level and eliminate other harmonics, simultaneously. Considering
Induction Motor (IM) as the inverter load, and wide DC bus voltage variations,
the inverter must operate in both over-modulation and linear modulation region.
Main objective of the modified SHE is to reduce harmonic torques through
finding the best switching angles. In this paper, optimization is based on
optimizing phasor equations in which harmonic torques are calculated. The
procedure of this method is that, first, the ratio of the same torque harmonics
is estimated, secondly, by using that estimation, the ratio of voltage
harmonics that generates homogeneous torques is calculated. For the estimation
and the calculation of the ratios motor parameter, mechanical speed of the
rotor, the applied frequency, and the concept of slip are used. The advantage
of this approach is highlighted when mechanical load and DC bus voltage
variations are taken into consideration. Simulation results are presented under
a wide range of working conditions in an induction motor to demonstrate the
effectiveness of the proposed method.

We refine existing general network optimization techniques, give new
characterizations for the class of problems to which they can be applied, and
show that they can also be used to solve various two-player games in almost
linear time. Among these is a new variant of the network interdiction problem,
where the interdictor wants to destroy high-capacity paths from the source to
the destination using a vertex-wise limited budget of arc removals. We also
show that replacing the limit average in mean payoff games by the maximum
weight results in a class of games amenable to these techniques.

Over forty years ago, Goethals and Seidel showed that if the adjacency
algebra of a strongly regular graph $X$ contains a Hadamard matrix then $X$ is
either of Latin square type or of negative Latin square type. We extend their
result to complex Hadamard matrices and find only three additional families of
parameters for which the strongly regular graphs have complex Hadamard matrices
in their adjacency algebras.
Moreover we show that there are only three distance regular covers of the
complete graph that give complex Hadamard matrices.

We consider correlation functions in one dimensional quantum integrable
models related to the algebra symmetries $\mathfrak{gl}(2|1)$ and
$\mathfrak{gl}(3)$. Using the algebraic Bethe Ansatz approach we develop an
expansion theorem, which leads to an infinite integral series in the
thermodynamic limit. The series is the generalization of the LeClair-Mussardo
series to nested Bethe Ansatz systems, and it is applicable both to one-point
and two-point functions. As an example we consider the ground state
density-density correlator in the Gaudin-Yang model of spin-1/2 Fermi
particles. Explicit formulas are presented in a special large coupling and
large imbalance limit.

A general framework for identification of permissible variable subsets
and development of structured variable selection methods
| null | null | null | null |
stat.ME
|
http://arxiv.org/licenses/nonexclusive-distrib/1.0/
|
In variable selection, a selection rule that prescribes the permissible sets
of selected variables (called a "selection dictionary") is desirable due to the
inherent structural constraints among the candidate variables. The methods that
can incorporate such restrictions can improve model interpretability and
prediction accuracy. Penalized regression can integrate selection rules by
assigning the coefficients to different groups and then applying penalties to
the groups. However, no general framework has been proposed to formalize
selection rules and their applications. In this work, we establish a framework
for structured variable selection that can incorporate universal structural
constraints. We develop a mathematical language for constructing arbitrary
selection rules, where the selection dictionary is formally defined. We show
that all selection rules can be represented as a combination of operations on
constructs, which can be used to identify the related selection dictionary. One
may then apply some criteria to select the best model. We show that the
theoretical framework can help to identify the grouping structure in existing
penalized regression methods. In addition, we formulate structured variable
selection into mixed-integer optimization problems which can be solved by
existing software. Finally, we discuss the significance of the framework in the
context of statistics.

Intimacy is a fundamental aspect of how we relate to others in social
settings. Language encodes the social information of intimacy through both
topics and other more subtle cues (such as linguistic hedging and swearing).
Here, we introduce a new computational framework for studying expressions of
the intimacy in language with an accompanying dataset and deep learning model
for accurately predicting the intimacy level of questions (Pearson's r=0.87).
Through analyzing a dataset of 80.5M questions across social media, books, and
films, we show that individuals employ interpersonal pragmatic moves in their
language to align their intimacy with social settings. Then, in three studies,
we further demonstrate how individuals modulate their intimacy to match social
norms around gender, social distance, and audience, each validating key
findings from studies in social psychology. Our work demonstrates that intimacy
is a pervasive and impactful social dimension of language.

Based on constructive interference in Sagnac waveguide loop, an efficient
scheme is proposed for selective frequency conversion and multifrequency modes
W entanglement via input-output formalism. We can adjust the probability
amplitudes of output photons by choosing parameter values properly. The tunable
probability amplitude will lead to the generation of output photon with a
selectable frequency and W photonic entanglement of different frequencies modes
in a wide range of parameter values. Our calculations show the present scheme
is robust to the deviation of parameters and spontaneous decay.

Towards Efficient and Domain-Agnostic Evasion Attack with
High-dimensional Categorical Inputs

Our work targets at searching feasible adversarial perturbation to attack a
classifier with high-dimensional categorical inputs in a domain-agnostic
setting. This is intrinsically an NP-hard knapsack problem where the
exploration space becomes explosively larger as the feature dimension
increases. Without the help of domain knowledge, solving this problem via
heuristic method, such as Branch-and-Bound, suffers from exponential
complexity, yet can bring arbitrarily bad attack results. We address the
challenge via the lens of multi-armed bandit based combinatorial search. Our
proposed method, namely FEAT, treats modifying each categorical feature as
pulling an arm in multi-armed bandit programming. Our objective is to achieve
highly efficient and effective attack using an Orthogonal Matching Pursuit
(OMP)-enhanced Upper Confidence Bound (UCB) exploration strategy. Our
theoretical analysis bounding the regret gap of FEAT guarantees its practical
attack performance. In empirical analysis, we compare FEAT with other
state-of-the-art domain-agnostic attack methods over various real-world
categorical data sets of different applications. Substantial experimental
observations confirm the expected efficiency and attack effectiveness of FEAT
applied in different application scenarios. Our work further hints the
applicability of FEAT for assessing the adversarial vulnerability of
classification systems with high-dimensional categorical inputs.

Hypergraph neural networks can model multi-way connections among nodes of the
graphs, which are common in real-world applications such as genetic medicine.
In particular, genetic pathways or gene sets encode molecular functions driven
by multiple genes, naturally represented as hyperedges. Thus, hypergraph-guided
embedding can capture functional relations in learned representations. Existing
hypergraph neural network models often focus on node-level or graph-level
inference. There is an unmet need in learning powerful representations of
subgraphs of hypergraphs in real-world applications. For example, a cancer
patient can be viewed as a subgraph of genes harboring mutations in the
patient, while all the genes are connected by hyperedges that correspond to
pathways representing specific molecular functions. For accurate inductive
subgraph prediction, we propose SubHypergraph Inductive Neural nEtwork (SHINE).
SHINE uses informative genetic pathways that encode molecular functions as
hyperedges to connect genes as nodes. SHINE jointly optimizes the objectives of
end-to-end subgraph classification and hypergraph nodes' similarity
regularization. SHINE simultaneously learns representations for both genes and
pathways using strongly dual attention message passing. The learned
representations are aggregated via a subgraph attention layer and used to train
a multilayer perceptron for inductive subgraph inferencing. We evaluated SHINE
against a wide array of state-of-the-art (hyper)graph neural networks, XGBoost,
NMF and polygenic risk score models, using large scale NGS and curated
datasets. SHINE outperformed all comparison models significantly, and yielded
interpretable disease models with functional insights.

For the identification of switched systems with a measured switching signal,
this work aims to analyze the effect of switching strategies on the estimation
error. The data for identification is assumed to be collected from globally
asymptotically or marginally stable switched systems under switches that are
arbitrary or subject to an average dwell time constraint. Then the switched
system is estimated by the least-squares (LS) estimator. To capture the effect
of the parameters of the switching strategies on the LS estimation error,
finite-sample error bounds are developed in this work. The obtained error
bounds show that the estimation error is logarithmic of the switching
parameters when there are only stable modes; however, when there are unstable
modes, the estimation error bound can increase linearly as the switching
parameter changes. This suggests that in the presence of unstable modes, the
switching strategy should be properly designed to avoid the significant
increase of the estimation error.

Newborn stars form within the localized, high density regions of molecular
clouds. The sequence and rate at which stars form in dense clumps and the
dependence on local and global environments are key factors in developing
descriptions of stellar production in galaxies. We seek to observationally
constrain the rate and latency of star formation in dense massive clumps that
are distributed throughout the Galaxy and to compare these results to proposed
prescriptions for stellar production. A sample of 24 micron-based Class~I
protostars are linked to dust clumps that are embedded within molecular clouds
selected from the APEX Telescope Large Area Survey of the Galaxy. We determine
the fraction of star-forming clumps, f*, that imposes a constraint on the
latency of star formation in units of a clump's lifetime. Protostellar masses
are estimated from models of circumstellar environments of young stellar
objects from which star formation rates are derived. Physical properties of the
clumps are calculated from 870 micron dust continuum emission and NH_3 line
emission. Linear correlations are identified between the star formation rate
surface density, Sigma_{SFR}, and the quantities Sigma_{H2}/tau_{ff} and
Sigma_{H2}/tau_{cross}, suggesting that star formation is regulated at the
local scales of molecular clouds. The measured fraction of star forming clumps
is 23%. Accounting for star formation within clumps that are excluded from our
sample due to 24 micron saturation, this fraction can be as high as 31%. Dense,
massive clumps form primarily low mass (< 1-2 msun) stars with emergent 24
micron fluxes below our sensitivity limit or are incapable of forming any stars
for the initial 70% of their lifetimes. The low fraction of star forming clumps
in the Galactic center relative to those located in the disk of the Milky Way
is verified.

Complex systems made of interacting elements are commonly abstracted as
networks, in which nodes are associated with dynamic state variables, whose
evolution is driven by interactions mediated by the edges. Markov processes
have been the prevailing paradigm to model such a network-based dynamics, for
instance in the form of random walks or other types of diffusions. Despite the
success of this modelling perspective for numerous applications, it represents
an over-simplification of several real-world systems. Importantly, simple
Markov models lack memory in their dynamics, an assumption often not realistic
in practice. Here, we explore possibilities to enrich the system description by
means of second-order Markov models, exploiting empirical pathway information.
We focus on the problem of community detection and show that standard network
algorithms can be generalized in order to extract novel temporal information
about the system under investigation. We also apply our methodology to temporal
networks, where we can uncover communities shaped by the temporal correlations
in the system. Finally, we discuss relations of the framework of second order
Markov processes and the recently proposed formalism of using non-backtracking
matrices for community detection.

We study 't Hooft anomalies for discrete global symmetries in bosonic
theories in 2, 3 and 4 dimensions. We show that such anomalies may arise in
gauge theories with topological terms in the action, if the total symmetry
group is a nontrivial extension of the global symmetry by the gauge symmetry.
Sometimes the 't Hooft anomaly for a d-dimensional theory with a global
symmetry G can be canceled by anomaly inflow from a (d+1)-dimensional
topological gauge theory with gauge group G. Such d-dimensional theories can
live on the surfaces of Symmetry Protected Topological Phases. We also give
examples of theories with more severe 't Hooft anomalies which cannot be
canceled in this way.

Fluctuation Theorem as a special case of Girsanov Theorem

Stochastic thermodynamics is an important development in the direction of
finding general thermodynamic principles for non-equilibrium systems. We
believe stochastic thermodynamics has the potential to benefit from the
measure-theoretic framework of stochastic differential equations. Towards this,
in this work, we show that Fluctuation Theorem (FT) is a special case of the
Girsanov theorem, which is an important result in the theory of stochastic
differential equations. We report that by employing Girsanov transformation of
measures between the forward and the reversed dynamics of a general class of
Langevin dynamic systems, we arrive at the Integral Fluctuation Relation.
Following the same approach, we derive the FT also for the overdamped case. Our
derivation is applicable to both transient and steady state conditions and can
also incorporate diffusion coefficients varying as a function of state and
time. We expect that the proposed method will be an easy route towards deriving
the FT irrespective of the complexity and non-linearity of the system.

We discuss the possibility of new generation neutrino and astroparticle
physics experiments exploiting the liquid Argon Time Projection Chamber (LAr
TPC) technique, following a graded strategy that envisions applications with
increasing detector masses (from 100 ton to 100 kton). The ICARUS R&D program
has already demonstrated that the technology is mature with the test of the
T600 detector at surface. Since 2003 we have been working with the conceptual
design of a very large LAr TPC with a mass of 50-100 kton to be built by
employing a monolithic technology based on the use of industrial, large volume,
cryogenic tankers developed by the petro-chemical industry. Such a detector, if
realized, would be an ideal match for a Super Beam, Beta Beam or Neutrino
Factory, covering a broad physics program that includes the detection of
atmospheric, solar and supernova neutrinos, and searches for proton decay, in
addition to the rich accelerator neutrino physics program. A "test module" with
a mass of the order of 10 kton operated underground or at shallow depth would
represent a necessary milestone towards the realization of the 100 kton
detector, with an interesting physics program on its own. In parallel, physics
is calling for a shorter scale application of the LAr TPC technique at the
level of 100 ton mass, for low energy neutrino physics and for use as a near
station setup in future long baseline neutrino facilities. We outline here the
main physics objectives and the design of such a detector for operation in the
upcoming T2K neutrino beam. We finally present the result of a series of R&D
studies conducted with the aim of validating the design of the proposed
detectors.

In the Fall of 2013, Georgia Tech offered a 'flipped' calculus-based
introductory mechanics class as an alternative to the traditional
large-enrollment lecture class. This class flipped instruction by introducing
new material outside of the classroom through pre-recorded, lecture videos.
Video lectures constituted students' initial introduction to course material.
We analyze how students engaged with online lecture videos via 'clickstream'
data, consisting of time-stamped interactions (plays, pauses, seeks, etc.) with
the online video player. Analysis of these events has shown that students may
be focusing on elements of the video that facilitate a 'correct' solution.

Supersonic engine development requires accurate and detailed measurements of
fluidic and thermodynamic parameters to optimize engine designs and benchmark
computational fluid dynamic (CFD) simulations. Here, we demonstrate that dual
frequency comb spectroscopy (DCS) with mode-locked frequency combs can provide
simultaneous absolute measurements of several flow parameters with low
uncertainty across a range of conditions owing to the broadband and ultrastable
optical frequency output of the lasers. We perform DCS measurements across a
6800-7200 cm-1 bandwidth covering hundreds of H2O absorption features resolved
with a spectral point spacing of 0.0067 cm-1 and point spacing precision of
1.68 x 10-10 cm-1. We demonstrate 2D profiles of velocity, temperature,
pressure, water mole fraction, and air mass flux in a ground-test dual-mode
ramjet at Wright-Patterson Air Force Base. The narrow angles of the measurement
beams offer sufficient spatial resolution to resolve properties across an
oblique shock train in the isolator and the thermal throat of the combustor. We
determine that the total measurement uncertainties for the various parameters
range from 1% for temperature to 9% for water vapor mole fraction, with the
absorption database/model that is used to interpret the data typically
contributing the most uncertainty (leaving the door open for even lower
uncertainty in the future). CFD at the various measurement locations show good
agreement, largely falling within the DCS measurement uncertainty for most
profiles and parameters.

The possibility of high-precision and rapid detection of pathologies on chest
X-rays makes it possible to detect the development of pneumonia at an early
stage and begin immediate treatment. Artificial intelligence can speed up and
qualitatively improve the procedure of X-ray analysis and give recommendations
to the doctor for additional consideration of suspicious images. The purpose of
this study is to determine the best models and implementations of the transfer
learning method in the binary classification problem in the presence of a small
amount of training data. In this article, various methods of augmentation of
the initial data and approaches to training ResNet and DenseNet models for
black-and-white X-ray images are considered, those approaches that contribute
to obtaining the highest results of the accuracy of determining cases of
pneumonia and norm at the testing stage are identified.

The microaerophilic magnetotactic bacterium Magnetospirillum gryphiswaldense
swims along magnetic field lines using a single flagellum at each cell pole. It
is believed that this magnetotactic behavior enables cells to seek optimal
oxygen concentration with maximal efficiency. We analyse the trajectories of
swimming M. gryphiswaldense cells in external magnetic fields larger than the
earth's field, and show that each cell can switch very rapidly (in < 0.2 s)
between a fast and a slow swimming mode. Close to a glass surface, a variety of
trajectories was observed, from straight swimming that systematically deviates
from field lines to various helices. A model in which fast (slow) swimming is
solely due to the rotation of the trailing (leading) flagellum can account for
these observations. We determined the magnetic moment of this bacterium using a
new method, and obtained a value of (2.0 $\pm$ 0.6) $\times$ $10^{-16}$ Am$^2$.
This value is found to be consistent with parameters emerging from quantitative
fitting of trajectories to our model.

We study the Poisson transform for differential forms on the real hyperbolic

Ground-based gamma-ray astronomy aims at reconstructing the energy and
direction of gamma rays from the extensive air showers they initiate in the
atmosphere. Imaging Atmospheric Cherenkov Telescopes (IACT) collect the
Cherenkov light induced by secondary charged particles in extensive air showers
(EAS), creating an image of the shower in a camera positioned in the focal
plane of optical systems. This image is used to evaluate the type, energy and
arrival direction of the primary particle that initiated the shower. This
contribution shows the results of a novel reconstruction method based on
likelihood maximization. The novelty with respect to previous likelihood
reconstruction methods lies in the definition of a likelihood per single camera
pixel, accounting not only for the total measured charge, but also for its
development over time. This leads to more precise reconstruction of shower
images. The method is applied to observations of the Crab Nebula acquired with
the Large Size Telescope prototype (LST-1) deployed at the northern site of the
Cherenkov Telescope Array.

A unified presentation of the perturbation and variational methods for the
generalized statistical mechanics based on Tsallis entropy is given here. In
the case of the variational method, the Bogoliubov inequality is generalized in
a very natural way following the Feynman proof for the usual statistical
mechanics. The inequality turns out to be form-invariant with respect to the
entropic index $q$. The method is illustrated with a simple example in
classical mechanics. The formalisms developed here are expected to be useful in
the discussion of nonextensive systems.

The tidal interaction of a Be star with a binary companion forms two spiral
arms that cause orbital modulation of the Be disc structure. The aim of this
work is to identify observables in which this modulation is apparent. The
structure of a Be disc in a coplanar circular binary system is computed with a
smoothed-particle hydrodynamics code, and a radiation transfer code calculates
the spectral energy distribution. Line depolarisation was confirmed, with
polarisation profiles nearly reverse to emission-line profiles. The continuum
flux maximizes for pole-on discs, but photometric variability maximizes for
edge-on discs. The linear polarisation exhibits one or two maxima per orbital
cycle. While polarisation variability in visible passbands is important only at
low inclinations, infrared bands may demonstrate high orbital variability even
at large inclinations. More evident is the modulation in the polarisation angle
(PA) for low inclinations. The latter can be used to track azimuthal
asymmetries for pole-on discs, where the spectroscopic variability in the
violet-to-red (V/R) emission-component ratio disappears. PA reversals coincide
with phases where V/R=1, tracking lines of sight directed towards regions where
the approaching and receding arms overlap. Continuum flux and polarisation are
mostly in phase for neighbouring wavelength regions. It is suggested that
studies of non-symmetric discs distorted by tidal forces from a secondary star
may be used to study disc variabilities of other origins.

Ultracold atom gases provide model systems in which many-body quantum physics
phenomena can be studied. Recent experiments on Fermi gases have realized a
phase transition to a Fermi superfluid state with strong interparticle
interactions. This system is a realization of the BCS-BEC crossover connecting
the physics of BCS superconductivity and that of Bose-Einstein condensation
(BEC). While many aspects of this system have been investigated, it has not yet
been possible to measure the single-particle excitation spectrum, which is a
fundamental property directly predicted by many-body theories. Here we show
that the single-particle spectral function of the strongly interacting Fermi
gas at T ~ Tc is dramatically altered in a way that is consistent with a large
pairing gap. We use photoemission spectroscopy to directly probe the elementary
excitations and energy dispersion in the Fermi gas of atoms. In these
photoemission experiments, an rf photon ejects an atom from our strongly
interacting system via a spin-flip transition to a weakly interacting state. We
measure the occupied single-particle density of states for an ultracold Fermi
gas of 40-potassium atoms at the cusp of the BCS-BEC crossover and on the BEC
side of the crossover, and compare these results to that for a nearly ideal
Fermi gas. Our results probe the many-body physics in a way that could be
compared to data for high-Tc superconductors. This new measurement technique
for ultracold atom gases, like photoemission spectroscopy for electronic
materials, directly probes low energy excitations and thus can reveal
excitation gaps and/or pseudogaps. Furthermore, this technique can provide an
analog to angle-resolved photoemission spectroscopy (ARPES) for probing
anisotropic systems, such as atoms in optical lattice potentials.

Forecasting time series with extreme events has been a challenging and
prevalent research topic, especially when the time series data are affected by
complicated uncertain factors, such as is the case in hydrologic prediction.
Diverse traditional and deep learning models have been applied to discover the
nonlinear relationships and recognize the complex patterns in these types of
data. However, existing methods usually ignore the negative influence of
imbalanced data, or severe events, on model training. Moreover, methods are
usually evaluated on a small number of generally well-behaved time series,
which does not show their ability to generalize. To tackle these issues, we
propose a novel probability-enhanced neural network model, called NEC+, which
concurrently learns extreme and normal prediction functions and a way to choose
among them via selective back propagation. We evaluate the proposed model on
the difficult 3-day ahead hourly water level prediction task applied to 9
reservoirs in California. Experimental results demonstrate that the proposed
model significantly outperforms state-of-the-art baselines and exhibits
superior generalization ability on data with diverse distributions.

This communication reports the -A isotherms and spectroscopic
characterizations of mixed Langmuir and Langmuir-Blodgett (LB) films of
nonamphiphilic 2, -biquinoline (BQ) molecules, mixed with polymethyl
methacrylate (PMMA) and stearic acid (SA). The pi-A isotherms and molefraction
versus area per molecule studies indicate complete immiscibility of sample (BQ)
and matrix (PMMA or SA) molecules. This immiscibility may lead to the formation
of microcrystalline aggregates of BQ molecules in the mixed LB films. The
scanning electron micrograph gives the visual evidence of microcrystalline
aggregates of BQ molecules in the mixed LB films. UV-Vis absorption,
fluorescence and excitation spectroscopic studies reveal the nature of these
microcrystalline aggregates. LB films lifted at higher surface pressure
indicate the formation of dimer or higher order n-mers.

We demonstrate experimentally the guiding of cold and slow ND3 molecules
along a thin charged wire over a distance of ~0.34 m through an entire
molecular beam apparatus. Trajectory simulations confirm that both linear and
quadratic high-field-seeking Stark states can be efficiently guided from the
beam source up to the detector. A density enhancement up to a factor 7 is
reached for decelerated beams with velocities ranging down to ~50 m/s generated
by the rotating nozzle technique.

Ultrahigh energy neutrinos can be used to explore the physics at the TeV

dimensions and the fundamental scale at the TeV. In particular, we discuss the
production of string resonances and the gravitational interactions
(multigraviton exchange and production of microscopic black holes) in these
models. We show that the new TeV physics could give observable signals in

The measurements carried out at LEP and SLC projected us into the precision
era of electroweak physics. This has also been relevant in the theoretical
interpretation of LHCb and Belle measurements of rare $B$ semileptonic decays,
paving the road for new physics with the inference of lepton universality
violation in $R_{K^{(*)}}$ ratios. The simplest explanation of these flavour
anomalies -- sizeable one-loop contributions respecting Minimal Flavour
Violation -- is currently disfavoured by electroweak precision data. In this
work, we discuss how to completely relieve the present tension between
electroweak constraints and one-loop minimal flavour violating solutions to
$R_{K^{(*)}}$. We determine the correlations in the Standard Model Effective
Field Theory that highlight the existence of such a possibility. Then, we
consider minimal extensions of the Standard Model where our
effective-field-theory picture can be realized. We discuss how these solutions
to $b \to s \ell \ell$ anomalies, respecting electroweak precision and without
any new source of flavour violation, may point to the existence of a
$Z^{\prime}$ boson at around the TeV scale, within the discovery potential of
LHC, or to leptoquark scenarios.

counterpart as some generalized nonlinear Schr\"{o}dinger equation. When the
anisotropy vanishes, from this result follows the well-known results
corresponding for the isotropic case, i.e. to the Heisenberg ferromagnet
equation and the focusing nonlinear Schr\"{o}dinger equation. The relations
between the LLE and the differential geometry of space curves in the local and
nonlocal cases are studied. Using the well-known Sym-Tafel formula, the soliton
surfaces induced by the LLE are briefly considered.

We compute the entanglement and R\'enyi entropy growth after a global quench
in various dimensions in free scalar field theory. We study two types of
quenches: a boundary state quench and a global mass quench. Both of these
quenches are investigated for a strip geometry in 1, 2, and 3 spatial
dimensions, and for a spherical geometry in 2 and 3 spatial dimensions. We
compare the numerical results for massless free scalars in these geometries
with the predictions of the analytical quasiparticle model based on EPR pairs,
and find excellent agreement in the limit of large region sizes. At subleading
order in the region size, we observe an anomalous logarithmic growth of
entanglement coming from the zero mode of the scalar.

Stability of Rotating Viscous and Inviscid flows

9 pages; 4 figures

Flow instability and turbulent transition can be well explained using a new
proposed theory--Energy gradient theory [1]. In this theory, the stability of a
flow depends on the relative magnitude of energy gradient in streamwise
direction and that in transverse direction, if there is no work input. In this
note, it is shown based on the energy gradient theory that inviscid non-uniform
flow is unstable if the energy in transverse direction is not constant. This
new finding breaks the classical linear theory from Rayleigh that inviscid flow
is unstable if the velocity profile has an inflection point in parallel flows
and inviscid flow is stable if the velocity profile has no inflection point in
parallel flow. Then, stability of rotating viscous and inviscid flows is
studied, and two examples of rotating flows (rotating rigid body motion and
free vortex motion) are shown, respectively.

to exploit the meaningful relational structure of the input data, which are
collected by a set of agents that communicate over a sparse network topology.
After formulating the centralized GCN training problem, we first show how to
make inference in a distributed scenario where the underlying data graph is
split among different agents. Then, we propose a distributed gradient descent
procedure to solve the GCN training problem. The resulting model distributes
computation along three lines: during inference, during back-propagation, and
during optimization. Convergence to stationary solutions of the GCN training
problem is also established under mild conditions. Finally, we propose an
optimization criterion to design the communication topology between agents in
order to match with the graph describing data relationships. A wide set of
numerical results validate our proposal. To the best of our knowledge, this is
the first work combining graph convolutional neural networks with distributed
optimization.

Understanding and controlling polyelectrolyte adsorption onto carbon
nanotubes is a fundamen- tal challenge in nanotechology. Polyelectrolytes have
been shown to stabilise nanotube suspensions through adsorbing onto the
nanotube surface, and polyelectrolyte-coated nanotubes are emerging as building
blocks for complex and addressable self-assembly. The conventional wisdom
suggests that polyelectrolyte adsorption onto nanotubes is driven by specific
chemical or van der Waals interac- tions. We develop a simple mean-field model
and show that ion-image attraction is a significant effect for adsorption onto
conducting nanotubes at low salt concentrations. Our theory suggests a simple
strategy to selectively and reversibly functionalize carbon nanotubes based on
their electronic structure which in turn modifies the ion-image attraction.

For a prime power $q$, $\F$ denotes the finite field of order $q$, and for
$m\geq 2$, $\Fm$ denotes the extension field of degree $m$. We establish a
characteristic function for the set of $(r,\, n)$-free elements of finite
cyclic $R$-module for the Euclidean domain $R$. Furthermore, we explore $(f,\,
g)$-freeness through polynomial values and finally give an expression for the
characteristic function for the set of $(f,\, g)$-free elements.

We investigate rare semileptonic \bar B -> \bar K^* l^+ l^- decays, providing
a comprehensive treatment of theoretical uncertainties in the low-q^2 region as
needed for interpreting current and future LHCb and B-factory data in terms of
the new physics search. We go beyond the usual focus on form-factor
uncertainties, paying proper attention to non-factorizable terms.
A central point is the systematic exploitation of the V-A structure of SM
weak interactions, which leads to the suppression of two helicity amplitudes
and some of the angular coefficients. We review how this works at the level of
(helicity) form factors, and show that the hierarchies extend to
non-factorizable terms. For virtual charm effects, we give an argument for it
in terms of light-cone QCD sum rules that continues to hold at the level of
"long-distance" Lambda_QCD^2/m_c^2 power corrections, reducing an important
source of theoretical uncertainty in any \bar B, \bar B_s -> V l^+ l^- (or \bar
B -> V gamma) decay. The contributions of the remaining hadronic weak
Hamiltonian respect a similar hierarchy. We employ a resonance model to
preclude (in the \bar B -> \bar K^* case) large long-distance corrections to
this.
A phenomenological part pays particular attention to the region of lowest
dilepton mass, 4 m_l^2 <= q^2 <= 2 GeV^2. Two observables remain theoretically
clean, implying a (theoretical) sensitivity to the real (imaginary) part of the
"right-handed" Wilson coefficient C_7' to 10% (1%) of C_7^SM, both in the
muonic and the electronic mode. We also show that there are two near-exact
relations between angular coefficients, even in the presence of new physics and
when lepton masses are not neglected.

Slowly driven elastic interfaces, such as domain walls in dirty magnets,
contact lines, or cracks proceed via intermittent motion, called avalanches. We
develop a field-theoretic treatment to calculate, from first principles, the
space-time statistics of instantaneous velocities within an avalanche. For
elastic interfaces at (or above) their (internal) upper critical dimension d >=
d_uc (d_uc = 2, 4 respectively for long-ranged and short-ranged elasticity) we
show that the field theory for the center of mass reduces to the motion of a
point particle in a random-force landscape, which is itself a random walk (ABBM
model). Furthermore, the full spatial dependence of the velocity correlations
is described by the Brownian-force model (BFM) where each point of the
interface sees an independent Brownian-force landscape. Both ABBM and BFM can
be solved exactly in any dimension d (for monotonous driving) by summing tree
graphs, equivalent to solving a (non-linear) instanton equation. This tree
approximation is the mean-field theory (MFT) for realistic interfaces in
short-ranged disorder. Both for the center of mass, and for a given Fourier
mode q, we obtain probability distribution functions (PDF's) of the velocity,
as well as the avalanche shape and its fluctuations (second shape). Within MFT
we find that velocity correlations at non-zero q are asymmetric under time
reversal. Next we calculate, beyond MFT, i.e. including loop corrections, the
1-time PDF of the center-of-mass velocity du/dt for dimension d< d_uc. The
singularity at small velocity P(du/dt) ~ 1/(du/dt)^a is substantially reduced
from a=1 (MFT) to a = 1 - 2/9 (4-d) + ... (short-ranged elasticity) and a = 1 -
4/9 (2-d) + ... (long-ranged elasticity). We show how the dynamical theory
recovers the avalanche-size distribution, and how the instanton relates to the
response to an infinitesimal step in the force.

In experiments on electron transport the macroscopic inhomogeneities in the
sample play a fundamental role. In this paper and a subsequent one we introduce
and develop a general formalism that captures the principal features of sample
inhomogeneities (density gradients, contact misalignments) in the magneto
resistance data taken from low mobility heterostructures. We present detailed
assessments and experimental investigations of the different regimes of
physical interest, notably the regime of semiclassical transport at weak
magnetic fields, the plateau-plateau transitions as well as the
plateau-insulator transition that generally occurs at much stronger values of
the external field only.
It is shown that the semiclassical regime at weak fields plays an integral
role in the general understanding of the experiments on the quantum Hall
regime. The results of this paper clearly indicate that the plateau-plateau
transitions, unlike the the plateau-insulator transition, are fundamentally
affected by the presence of sample inhomogeneities. We propose a universal
scaling result for the magneto resistance parameters. This result facilitates,
amongst many other things, a detailed understanding of the difficulties
associated with the experimental methodology of H.P. Wei et.al in extracting
the quantum critical behavior of the electron gas from the transport
measurements conducted on the plateau-plateau transitions.

JIMWLK equation tells how gauge invariant higher order Wilson line
correlators would evolve at high energy. In this article we present a
convenient integro-differential form of this equation, for 2n-tuple correlator,
where all real and virtual terms are explicit. The `real' terms correspond to
splitting (say at position z) of this 2n-tuple correlator to various pairs of
2m-tuple and (2n+2-2m)-tuple correlators whereas `virtual' terms correspond to
splitting into pairs of 2m-tuple and (2n-2m)-tuple correlators. Kernels of
virtual terms with m=0 (no splitting) and of real terms with m=1 (splitting
with atleast one dipole) have poles and when integrated over z they do generate
ultraviolet logarithmic divergences, separately for real and virtual terms.
Except these two cases in all other terms the corresponding kernels, separately
for real and virtual terms, have rather soften ultraviolet singularity and when
integrated over z do not generate ultraviolet logarithmic divergences. We went
on to study the solution of the JIMWLK equation for the 2n-tuple Wilson line
correlator in the strong scattering regime where all transverse distances are
much larger than inverse saturation momentum and shown that it also exhibits
geometric scaling like color dipole deep inside saturation region.

Let (X k) be a strictly stationary sequence of random variables with values
in some Polish space E and common marginal $\mu$, and (A k) k>0 be a sequence
of Borel sets in E. In this paper, we give some conditions on (X k) and (A k)
under which the events {X k $\in$ A k } satisfy the Borel-Cantelli (or strong
Borel-Cantelli) property. In particular we prove that, if $\mu$(lim sup n A n)
> 0, the Borel-Cantelli property holds for any absolutely regular sequence. In
case where the A k 's are nested, we show, on some examples, that a rate of
convergence of the mixing coefficients is needed. Finally we give extensions of
these results to weaker notions of dependence, yielding applications to
non-irreducible Markov chains and dynamical systems.

A Deep Learning Based Discontinuous Galerkin Method for Hyperbolic
Equations with Discontinuous Solutions and Random Uncertainties
| null | null | null | null |

We propose a deep learning based discontinuous Galerkin method (D2GM) to
solve hyperbolic equations with discontinuous solutions and random
uncertainties. The main computational challenges for such problems include
discontinuities of the solutions and the curse of dimensionality due to
uncertainties. Deep learning techniques have been favored for high-dimensional
problems but face difficulties when the solution is not smooth, thus have so
far been mainly used for viscous hyperbolic system that admits only smooth
solutions. We alleviate this difficulty by setting up the loss function using
discrete shock capturing schemes--the discontinous Galerkin method as an
example--since the solutions are smooth in the discrete space. The convergence
of D2GM is established via the Lax equivalence theorem kind of argument. The
high-dimensional random space is handled by the Monte-Carlo method. Such a
setup makes the D2GM approximate high-dimensional functions over the random
space with satisfactory accuracy at reasonable cost. The D2GM is found
numerically to be first-order and second-order accurate for (stochastic) linear
conservation law with smooth solutions using piecewise constant and piecewise
linear basis functions, respectively. Numerous examples are given to verify the
efficiency and the robustness of D2GM with the dimensionality of random
variables up to $200$ for (stochastic) linear conservation law and (stochastic)
Burgers' equation.

Ever since the pioneering work of Schmidt a half-century ago there has been
great interest in finding an appropriate empirical relation that would directly
link some property of interstellar gas with the process of star formation
within it. Schmidt conjectured that this might take the form of a power-law
relation between the rate of star formation (SFR) and the surface density of
interstellar gas. However, recent observations suggest that a linear scaling
relation between the total SFR and the amount of dense gas within molecular
clouds appears to be the underlying physical relation that most directly
connects star formation with interstellar gas from scales of individual GMCs to
those encompassing entire galaxies both near and far. Although Schmidt
relations are found to exist within local GMCs, there is no Schmidt relation
observed between GMCs. The implications of these results for interpreting and
understanding the Kennicutt-Schmidt scaling law for galaxies are discussed.

We show that indecomposable exact module categories over the category Rep H
of representations of a finite-dimensional Hopf algebra H are classified by
left comodule algebras, H-simple from the right and with trivial coinvariants,
up to equivariant Morita equivalence. Specifically, any indecomposable exact
module categories is equivalent to the category of finite-dimensional modules
over a left comodule algebra. This is an alternative approach to the results of
Etingof and Ostrik. For this, we study the stabilizer introduced by Yan and Zhu
and show that it coincides with the internal Hom. We also describe the
correspondence of module categories between Rep H and Rep (H^*).

This paper presents the development of a real time tracking algorithm that
runs on a 1.2 GHz PC/104 computer on-board a small UAV. The algorithm uses zero
mean normalized cross correlation to detect and locate an object in the image.
A kalman filter is used to make the tracking algorithm computationally
efficient. Object position in an image frame is predicted using the motion
model and a search window, centered at the predicted position is generated.
Object position is updated with the measurement from object detection. The
detected position is sent to the motion controller to move the gimbal so that
the object stays at the center of the image frame. Detection and tracking is
autonomously carried out on the payload computer and the system is able to work
in two different methods. The first method starts detecting and tracking using
a stored image patch. The second method allows the operator on the ground to
select the interest object for the UAV to track. The system is capable of
re-detecting an object, in the event of tracking failure. Performance of the
tracking system was verified both in the lab and on the field by mounting the
payload on a vehicle and simulating a flight. Tests show that the system can
detect and track a diverse set of objects in real time. Flight testing of the
system will be conducted at the next available opportunity.

A novel exact solution of the multichannel spin-$S$ Kondo model is presented,
based on a lattice path integral approach of the single channel spin-1/2 case.
The spin exchange between the localized moment and the host is of $XXZ$-type,
including the isotropic $XXX$ limit. The free energy is given by a finite set
of non-linear integral equations, which allow for an accurate determination of
high- and low-temperature scales.

We show that rotation of the magnetic field off the plane of twin boundaries
(TB's) induces transition of an ordered vortex solid phase to a disordered one.
This transition arises due to appearance of transverse deformations of vortex
lines near the TB's, $u_{t,TB}$, the amplitude of which satisfies the Lindemann
criteria, $u_{t,rp}=c_La_0$. This order-disorder transition is accompanied by
an increase in the depinning current, by crossover from an elastic creep to
plastic one, and by appearance of the $S$-shaped voltage-current
characteristics.

To embed the seesaw mechanism in the MSSM, two or three right-handed neutrino
supermultiplets, $N_i$, have to be added to the model. In this framework, the
supersymmetry breaking potential will include a new term called neutrino
$B$-term: $MB_\nu \tilde{N} \tilde{N}/2$. In this talk, we present a toy model
that generates a large neutrino $B$-term keeping other supersymmetry breaking
parameters small. We then review the consequences of having a large neutrino
$B$-term on the electroweak symmetry breaking parameters and electric dipole
moments (EDMs) of elementary particles.

Distinguishing between dynamical and static Rashba effects in hybrid

The dynamical and static Rashba effects in hybrid methylammonium (MA) lead
halide perovskites have recently been theoretically predicted. However, only
the static effect was experimentally confirmed so far. Here we report on the
dynamical Rashba effect observed using snapshot transient absorption spectral
imaging with 400 nm pumping for a fully encapsulated film of 20-nm-sized 3D
MAPbBr3 nanocrystals. The effect causes a 240 meV splitting of the
lowest-energy absorption bleaching band, initially appearing over sub-ps
timescale and progressively stabilizing to 60 meV during 500 ps. The integrated
intensities of the split subbands demonstrate a photon-helicity-dependent
asymmetry, thus proving the Rashba-type splitting and providing direct
experimental evidence for the Rashba spin-split edge states in lead halide
perovskite materials. The ultrafast dynamics is governed by the relaxation of
two-photon-excited electrons in the Rashba spin-split system caused by a
built-in electric field originating from dynamical charge separation in the
entire MAPbBr3 nanocrystal.

A different reason for the apparent weakness of the gravitational interaction
is advanced, and its consequences for Hawking evaporation of a Schwarzschild
black hole are investigated. A simple analytical formulation predicts that
evaporating black holes will undergo a type of phase transition resulting in
variously long-lived objects of reasonable sizes, with normal thermodynamic
properties and inherent duality characteristics. Speculations on the
implications for particle physics and for some recently-advanced new paradigms
are explored.

The nature of hadrons is one of the most fundamental mysteries of physics. It
is generally agreed that they are made of "colored" quarks, which move nearly
free at short scales but are confined inside hadrons by strong interactions at
large distances. Because of confinement, quarks are never directly observable
and, experimentally, their properties can be tested only indirectly, via high
energy collisions. Here we show that superinsulating films realize a complete,
one-color model system of hadron physics with Cooper pairs playing the role of
quarks. We report measurements on highly controlled NbTiN films that provide a
window into the interior of "Cooper pair mesons" and present the first direct
evidence of asymptotic freedom, `t Hooft's dual superconductivity confinement
mechanism, and magnetic monopoles.

under extensions of number fields M/K. We show that in many cases, including
Sylow metacyclic and nilpotent groups whose order is prime to the number of
roots of unity in M, a K-admissible group G is M-admissible if and only if G
satisfies the easily verifiable Liedahl condition over M.

Improving Domain-Adapted Sentiment Classification by Deep Adversarial
Mutual Learning

Domain-adapted sentiment classification refers to training on a labeled
source domain to well infer document-level sentiment on an unlabeled target
domain. Most existing relevant models involve a feature extractor and a
sentiment classifier, where the feature extractor works towards learning
domain-invariant features from both domains, and the sentiment classifier is
trained only on the source domain to guide the feature extractor. As such, they
lack a mechanism to use sentiment polarity lying in the target domain. To
improve domain-adapted sentiment classification by learning sentiment from the
target domain as well, we devise a novel deep adversarial mutual learning
approach involving two groups of feature extractors, domain discriminators,
sentiment classifiers, and label probers. The domain discriminators enable the
feature extractors to obtain domain-invariant features. Meanwhile, the label
prober in each group explores document sentiment polarity of the target domain
through the sentiment prediction generated by the classifier in the peer group,
and guides the learning of the feature extractor in its own group. The proposed
approach achieves the mutual learning of the two groups in an end-to-end
manner. Experiments on multiple public datasets indicate our method obtains the
state-of-the-art performance, validating the effectiveness of mutual learning
through label probers.

In this brief note we prove orbifold equivalence between two potentials
described by strangely dual exceptional unimodular singularities of type
$K_{14}$ and $Q_{10}$ in two different ways. The matrix factorizations proving
the orbifold equivalence give rise to equations whose solutions are permuted by
Galois groups which differ for different expressions of the same singularity.

Fitting probabilistic models to data is often difficult, due to the general
intractability of the partition function and its derivatives. Here we propose a
new parameter estimation technique that does not require computing an
intractable normalization factor or sampling from the equilibrium distribution
of the model. This is achieved by establishing dynamics that would transform
the observed data distribution into the model distribution, and then setting as
the objective the minimization of the KL divergence between the data
distribution and the distribution produced by running the dynamics for an
infinitesimal time. Score matching, minimum velocity learning, and certain
forms of contrastive divergence are shown to be special cases of this learning
technique. We demonstrate parameter estimation in Ising models, deep belief
networks and an independent component analysis model of natural scenes. In the
Ising model case, current state of the art techniques are outperformed by at
least an order of magnitude in learning time, with lower error in recovered
coupling parameters.

Let C and D be digraphs. A mapping $f:V(D)\to V(C)$ is a C-colouring if for
every arc $uv$ of D, either $f(u)f(v)$ is an arc of C or $f(u)=f(v)$, and the
preimage of every vertex of C induces an acyclic subdigraph in D. We say that D
is C-colourable if it admits a C-colouring and that D is uniquely C-colourable
if it is surjectively C-colourable and any two C-colourings of D differ by an
automorphism of C. We prove that if a digraph D is not C-colourable, then there
exist digraphs of arbitrarily large girth that are D-colourable but not
C-colourable. Moreover, for every digraph D that is uniquely D-colourable,
there exists a uniquely D-colourable digraph of arbitrarily large girth. In
particular, this implies that for every rational number $r\geq 1$, there are
uniquely circularly r-colourable digraphs with arbitrarily large girth.

Directly measuring the Higgs self-coupling is of great importance for testing
the Brout-Englert-Higgs mechanism in the Standard Model. As a scattering that
contains the direct information from the Higgs self-coupling, we investigate
the process $\mu^-\mu^+\rightarrow HH$ in the threshold region. We calculate
the one-loop corrections to the cross section and consider the non-perturbative
contribution from the Higgs self-interactions in the final state. It is found
that the scattering in the nonrelativistic domain could be an especial process
to testing the Higgs sector directly.

In finite probability theory, events are subsets of the outcome set. Subsets
can be represented by 1-dimensional column vectors. By extending the
representation of events to two dimensional matrices, we can introduce
"superposition events." Probabilities are introduced for classical events,
superposition events, and their mixtures by using density matrices. Then
probabilities for experiments or `measurements' of all these events can be
determined in a manner exactly like in quantum mechanics (QM) using density
matrices. Moreover the transformation of the density matrices induced by the
experiments or `measurements' is the Luders mixture operation as in QM. And
finally by moving the machinery into the n-dimensional vector space over Z_2,
different basis sets become different outcome sets. That `non-commutative'
extension of finite probability theory yields the pedagogical model of quantum
mechanics over Z_2 that can model many characteristic non-classical results of
QM.

This paper is about positive scalar curvature on a compact manifold $X$ with

question of when $X$ has a positive scalar curvature metric which is a product
metric near $\partial X$, or when $X$ has a positive scalar curvature metric
with positive mean curvature on the boundary, and more generally, we study the
relationship between boundary conditions on $\partial X$ for positive scalar
curvature metrics on $X$ and the positive scalar curvature problem for the
double $M=\operatorname{Dbl}(X,\partial X)$.

The persistent current, i.e. the equilibrium direct electric current
circulating in realistic rings, some authors interpreted as dissipationless in
spite of non-zero resistance of the rings, whereas the other one suppose that
this current can not decay at dissipation. The observation of potential
difference connected with the persistent current may give new important
information about paradoxical nature of this quantum phenomena observed in
nanostructures.

The interaction energy for the indirect-exchange or
Ruderman-Kittel-Kasuva-Yosida (RKKY) interaction between magnetic spins
localized on lattice sites of the $\alpha$-${\cal T}_3$ model is calculated
using linear response theory. In this model, the $\texttt{AB}$-honeycomb
lattice structure is supplemented with $\texttt{C}$ atoms at the centers of the
hexagonal lattice. This introduces a parameter $\alpha$ for the ratio of the
hopping integral from hub-to-rim and that around the rim of the hexagonal
lattice. A valley and $\alpha$-dependent retarded Greens function matrix is
used to form the susceptibility. Analytic and numerical results are obtained
for undoped $\alpha$-${\cal T}_3$, when the chemical potential is finite and
also in the presence of an applied magnetic field. We demonstrate the
anisotropy of these results when the magnetic impurities are placed on the
$\texttt{A,B}$ and $\texttt{C}$ sublattice sites. Additionally, comparison of
the behavior of the susceptibility of $\alpha$-${\cal T}_3$ with graphene shows
that there is a phase transition at $\alpha=0$.

For Majorana neutrino masses the lowest dimensional operator possible is the
Weinberg operator at $d=5$. Here we discuss the possibility that neutrino
masses originate from higher dimensional operators. Specifically, we consider
all tree-level decompositions of the $d=9$, $d=11$ and $d=13$ neutrino mass
operators. With renormalizable interactions only, we find 18 topologies and 66
diagrams for $d=9$, and 92 topologies plus 504 diagrams at the $d=11$ level. At
$d=13$ there are already 576 topologies and 4199 diagrams. However, among all
these there are only very few genuine neutrino mass models: At $d=(9,11,13)$ we
find only (2,2,2) genuine diagrams and a total of (2,2,6) models. Here, a model
is considered genuine at level $d$ if it automatically forbids lower order
neutrino masses {\em without} the use of additional symmetries. We also briefly
discuss how neutrino masses and angles can be easily fitted in these
high-dimensional models.

The initial conditions, physics, and outcome of planet formation are now
constrained by detailed observations of protoplanetary disks, laboratory
experiments, and the discovery of thousands of extrasolar planetary systems.
These developments have broadened the range of processes that are considered
important in planet formation, to include disk turbulence, radial drift, planet
migration, and pervasive post-formation dynamical evolution. The N-body
collisional growth of planetesimals and protoplanets, and the physics of
planetary envelopes - key ingredients of the classical model - remain central.
I provide an overview of the current status of planet formation theory, and
discuss how it connects to observations.

Ab initio Monte Carlo simulations have been performed to determine the
equilibrium properties of liquid lithium and lithium clusters at different
temperatures. First-principles density-functional methods were employed to
calculate the potential-energy change for each proposed change of
configuration, which was then accepted or rejected according to the Metropolis
Monte Carlo scheme. The resulting structural properties are compared to data
from experimental measurements and ab initio molecular dynamics simulations. It
is shown that accurate structural information can be obtained with ab initio
Monte Carlo simulations at computational costs comparable to ab initio
molecular dynamics methods. We demonstrate that ab initio Monte Carlo
simulations for the properties of fairly large condensed-matter systems at
nonzero temperatures are feasible.

Here we consider the possibility that the Fermi arcs observed in ARPES
experiments result from interaction of valence band electrons with negative-U
centers (NUCs) which are formed under doping on the pairs of neighboring Cu
cations in CuO2 plane. This interaction results in two-particle hybridization
and vanishing of the gap over the part of Fermi contour. Furthermore the
transitions of electrons to NUCs result in the generation of free hole
carriers. Just these carriers rather than doping induced charges provide
conduction in the normal state.

There has recently been growing evidence that atrial fibrillation (AF), the
most common cardiac arrhythmia, is independently associated with the risk of
dementia. This represents a very recent frontier with high social impact for
the number of individuals involved and for the expected increase in AF
incidence in the next 40 years. Although a number of potential haemodynamic
processes, such as microembolisms, altered cerebral blood flow, hypoperfusion
and microbleeds, arise as connecting links between the two pathologies, the
causal mechanisms are far from clear. An in silico approach is proposed that
combines in sequence two lumped-parameter schemes, for the cardiovascular
system and the cerebral circulation. The systemic arterial pressure is obtained
from the cardiovascular system and used as the input for the cerebral
circulation, with the aim of studying the role of AF on the cerebral
haemodynamics with respect to normal sinus rhythm (NSR), over a 5000 beat
recording. In particular, the alteration of the haemodynamic (pressure and
flowrate) patterns in the microcirculation during AF is analysed by means of
different statistical tools, from correlation coefficients to autocorrelation
functions, crossing times, extreme values analysis and multivariate linear
regression models. A remarkable signal alteration, such as a reduction in
signal correlation (NSR, about 3 s; AF, less than 1 s) and increased
probability (up to three to four times higher in AF than in NSR) of extreme
value events, emerges for the peripheral brain circulation. The described
scenario offers a number of plausible cause-effect mechanisms that might
explain the occurrence of critical events and the haemodynamic links relating
to AF and dementia.

Phased Flight Trajectory Prediction with Deep Learning

The unprecedented increase of commercial airlines and private jets over the
next ten years presents a challenge for air traffic control. Precise flight
trajectory prediction is of great significance in air transportation
management, which contributes to the decision-making for safe and orderly
flights. Existing research and application mainly focus on the sequence
generation based on historical trajectories, while the aircraft-aircraft
interactions in crowded airspace especially the airspaces near busy airports
have been largely ignored. On the other hand, there are distinct
characteristics of aerodynamics for different flight phases, and the trajectory
may be affected by various uncertainties such as weather and advisories from
air traffic controllers. However, there is no literature fully considers all
these issues. Therefore, we proposed a phased flight trajectory prediction
framework. Multi-source and multi-modal datasets have been analyzed and mined
using variants of recurrent neural network (RNN) mixture. To be specific, we
first introduce spatio temporal graphs into the low-altitude airway prediction
problem, and the motion constraints of an aircraft are embedded to the
inference process for reliable forecasting results. In the en-route phase, the
dual attention mechanism is employed to adaptively extract much more important
features from overall datasets to learn the hidden patterns in dynamical
environments. The experimental results demonstrate our proposed framework can
outperform state-of-the-art methods for flight trajectory prediction for large
passenger/transport airplanes.

In this paper we investigate collision detection and avoidance in a vehicular
network of full duplex (FD) operating nodes. Each vehicle in this network
senses the energy level of the channel before and during its transmission. The
measured energy is compared against a dynamic threshold which is preset based
on the target detection probability, transmitter's power, sensing time and
self-interference cancellation (SIC) capability of the vehicles' on board units
(OBU). Probabilities of detection and false alarm, detection threshold before
and during transmission, and effect of residual self interference (SI) on these
metrics have been formulated. It is shown that the proposed scheme would
experience a shorter collision duration. Meanwhile, it also requires a minimum
SIC capability for acceptable operation, below which, system throughput would
be poor due to high false alarm probability. Numerical simulations verify the
accuracy of our analysis. They also illustrate that the proposed model perform
better than the fixed threshold strategy. A trade-off between half duplex (HD)
and FD has been found and the scheme would be applicable even if SIC capability
of OBUs is relatively poor, with no need for complicated and expensive devices
for future vehicular communication.

This paper reviews basic results from a theory of the classical probabilities
in state-averaged complete active space self-consistent field wave functions.
It is proposed that a canonical (Boltzmann) weighting scheme makes the
self-consistency condition invariant with respect to configurational
transformations that act locally on the support of the equilibrated SA-CASSCF
ensemble. This is illustrated with a complete active space valence-bond (CASVB)
analysis of low-energy electronic states in a monomethine cyanine dye.

The four moment theorem asserts, roughly speaking, that the joint
distribution of a small number of eigenvalues of a Wigner random matrix (when
measured at the scale of the mean eigenvalue spacing) depends only on the first
four moments of the entries of the matrix. In this paper, we extend the four
moment theorem to also cover the coefficients of the \emph{eigenvectors} of a
Wigner random matrix. A similar result (with different hypotheses) has been
proved recently by Knowles and Yin, using a different method.
As an application, we prove some central limit theorems for these
eigenvectors. In another application, we prove a universality result for the
resolvent, up to the real axis. This implies universality of the inverse
matrix.

The BlueWalker 3 Satellite Has Faded
| null | null | null | null |
astro-ph.IM

|
Observations of BlueWalker 3 (BW3) beginning on December 8 of this year
indicate that its apparent brightness had decreased. We postulate that the
orbital beta angle and resultant solar power considerations required an
adjustment to the satellite attitude around that time. So, the nominally zenith
facing side of the flat-panel shaped spacecraft, which supports the solar
array, was tilted toward the Sun. Consequently, the nadir side, which is seen
by observers on the ground, was mostly dark. Thus, BW3 has generally appeared
faint and on some occasions was not seen at all. The amount of fading was up to
4 magnitudes. Numerical modeling indicates that the amount of tilt was in the
range 13{\deg} to 16{\deg}. This situation indicates the improvement in the
appearance of BW3 from the ground that can be achieved with small tilts of the
spacecraft. Satellite operators and astronomers can jointly address the adverse
impact of bright satellites on celestial observations based on this finding.

Using the concept of an ideal phase-conjugating mirror we demonstrate that
regardless of internal physical mechanism the phase-conjugation of a singular
laser beam is accompanied by excitation within the mirror of internal waves
which carry doubled angular momentum in order to match angular momentum
conservation. For a Brillouin hypersound wavefront-reversal mirror this means
that each elementary optical vortex belonging to a speckle pattern emits an
acoustical vortex wave with doubled topological charge. The exact spatial
profiles of light intensity and the intensity of hypersound in the vicinity of
the phase singularity are obtained. These spiral profiles have a form of double
helix which rotates with the frequency of sound. An optoacoustic experiment is
proposed for visualization of the wavefront reversal of twisted optical beams
and tunable twisted sound generation.

Divide-and-Assemble: Learning Block-wise Memory for Unsupervised Anomaly
Detection

Reconstruction-based methods play an important role in unsupervised anomaly
detection in images. Ideally, we expect a perfect reconstruction for normal
samples and poor reconstruction for abnormal samples. Since the
generalizability of deep neural networks is difficult to control, existing
models such as autoencoder do not work well. In this work, we interpret the
reconstruction of an image as a divide-and-assemble procedure. Surprisingly, by
varying the granularity of division on feature maps, we are able to modulate
the reconstruction capability of the model for both normal and abnormal
samples. That is, finer granularity leads to better reconstruction, while
coarser granularity leads to poorer reconstruction. With proper granularity,
the gap between the reconstruction error of normal and abnormal samples can be
maximized. The divide-and-assemble framework is implemented by embedding a
novel multi-scale block-wise memory module into an autoencoder network.
Besides, we introduce adversarial learning and explore the semantic latent
representation of the discriminator, which improves the detection of subtle
anomaly. We achieve state-of-the-art performance on the challenging MVTec AD
dataset. Remarkably, we improve the vanilla autoencoder model by 10.1% in terms
of the AUROC score.

MUIT: A Middleware for Adaptive Mobile Web-based User Interfaces in

| null | null | null | null |

http://arxiv.org/licenses/nonexclusive-distrib/1.0/
|
In enterprise organizations, the Bring-Your-Own-Device (BYOD) requirement has
become prevalent as employees use their own mobile devices to process the
workflow-oriented tasks. Consequently, it calls for approaches that can quickly
develop and integrate mobile user interactions into existing business
processes, and adapt to various contexts. However, designing, developing and
deploying adaptive and mobile-oriented user interfaces for existing process
engines are non-trivial, and require significant systematic efforts. To address
this issue, we present a novel middleware-based approach, called MUIT, to
developing and deploying the Mobility, User Interactions and Tasks into WS-BPEL
engines. MUIT can be seamlessly into WS-BPEL without intrusions of existing
process instances. MUIT provides a Domain-Specific Language (DSL) that provides
some intuitive APIs to support the declarative development of adaptive,
mobile-oriented, and Web-based user interfaces in WS-BPEL. The DSL can
significantly improve the development of user interactions by preventing
arbitrarily mixed codes, and its runtime supports satisfactory user
experiences. We implement a proof- of-concept prototype by integrating MUIT
into the commodity WS-BPEL-based Apusic Platform, and evaluate the performance
and usability of MUIT platform.
