description: Observing sequences have shown that the major noise source limitation in high-contrast imaging is due to the presence of quasi-static speckles. The timescale on which quasi-static speckles evolve, is determined by various factors, among others mechanical or thermal deformations. Understanding of these time-variable instrumental speckles, and especially their interaction with other aberrations, referred to as the pinning effect, is paramount for the search of faint stellar companions. The temporal evolution of quasi-static speckles is for instance required for a quantification of the gain expected when using angular differential imaging (ADI), and to determine the interval on which speckle nulling techniques must be carried out. Following an early analysis of a time series of adaptively corrected, coronagraphic images obtained in a laboratory condition with the High-Order Test bench (HOT) at ESO Headquarters, we confirm our results with new measurements carried out with the SPHERE instrument during its final test phase in Europe. The analysis of the residual speckle pattern in both direct and differential coronagraphic images enables the characterization of the temporal stability of quasi-static speckles. Data were obtained in a thermally actively controlled environment reproducing realistic conditions encountered at the telescope. The temporal evolution of the quasi-static wavefront error exhibits linear power law, which can be used to model quasi-static speckle evolution in the context of forthcoming high-contrast imaging instruments, with implications for instrumentation (design, observing strategies, data reduction). Such a model can be used for instance to derive the timescale on which non-common path aberrations must be sensed and corrected. We found in our data that quasi-static wavefront error increases with ~0.7 angstrom per minute.

description: Using a new experimental design, we compare how subjects form beliefs in an investorclient setup under varying degrees of liability. Our results re ect the importance of social preferences when making investment decisions for others. We show that when investors have no liability, those with stronger social preferences are more optimistic about the probability that their investment results in a gain. In other words, we nd that social preferences appear to be correlated with motivated beliefs. This nding suggests the existence of cognitive biases in nancial decision-making and supports the recent literature on the formation of motivated beliefs under limited liability (Barberis, 2015; B enabou and Tirole, 2016).

description: Since nine years experiments have been observing a host of exotic states decaying into heavy quarkonia. The interpretation of most of them still remains uncertain and, in some cases, controversial, notwithstanding a considerable progress has been made on the quality of the experimental information available and a number of ideas and models have been put forward to explain the observations. In this mini-review we will summarize the measurements, with the most recent updates, and list the useful ones yet to be done. We will discuss the problem of the spin of the X, which could hide some major surprise on its interpretation, and review some more phenomenological issues debated in the field.

description: Pion dissociation by the Mott effect in quark plasma is described within the generalized Beth-Uhlenbeck approach on the basis of the PNJL model which allows for a unified description of bound, resonant and scattering states. As a first approximation, we utilize the Breit-Wigner ansatz for the spectral function and clarify its relation to the complex mass pole solution of the pion Bethe-Salpeter equation. Application of the Levinson theorem proves that describing the pion Mott dissociation solely by means of spectral broadening of the pion bound state beyond T_Mott leaves out a significant aspect. Thus we acknowledge the importance of the continuum of scattering states and show its role for the thermodynamics of pion dissociation.

description: Small populations with limited range are often threatened by inbreeding and reduced genetic diversity, which can reduce fitness and exacerbate population decline. One of the most extreme natural examples is the Devil's Hole pupfish (Cyprinodon diabolis), an iconic and critically endangered species with the smallest known range of any vertebrate. This species has experienced severe declines in population size over the last 30 years and suffered major bottlenecks in 2007 and 2013, when the population shrunk to 38 and 35 individuals, respectively. Here, we analysed 30 resequenced genomes of desert pupfishes from Death Valley, Ash Meadows and surrounding areas to examine the genomic consequences of small population size. We found extremely high levels of inbreeding (FROH = 0.34–0.81) and an increased amount of potentially deleterious genetic variation in the Devil's Hole pupfish as compared to other species, including unique, fixed loss-of-function alleles and deletions in genes associated with sperm motility and hypoxia. Additionally, we successfully resequenced a formalin-fixed museum specimen from 1980 and found that the population was already highly inbred prior to recent known bottlenecks. We thus document severe inbreeding and increased mutation load in the Devil's Hole pupfish and identify candidate deleterious variants to inform management of this conservation icon.

Motivic L-Function Identities from CFT and Arithmetic Mirror Symmetry

Publisher: name: arXiv

Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: Exactly solvable mirror pairs of Calabi-Yau threefolds of hypersurface type exist in the class of Gepner models that include nondiagonal affine invariants. Motivated by the string modular interpretation established previously for models in this class it is natural to ask whether the arithmetic structure of mirror pairs of varieties reflects the fact that as conformal field theories they are isomorphic. Mirror symmetry in particular predicts that the L-functions of the Ω-motives of such pairs are identical. In the present paper this prediction is confirmed by showing that the Ω-motives of exactly solvable mirror pairs are isomorphic. This follows as a corollary from a more general result establishing an isomorphism between nondiagonally and diagonally induced motives in this class of varieties. The motivic approach formulated here circumvents the difficulty that no mirror construction of the Hasse-Weil zeta function is known.

description: Metals and coating materials, with best material properties are highly desired in the field of engineering to control the stresses and strains, that play important role in design strategies. The crankshaft, an important part of tank engine, depends on the cranking mechanism in the internal combustion engine. The function of the crankshaft is to convert the sliding motion of the piston into rotary motion. Since most industrial mechanisms and processes make more efficient use of rotary motions rather than displacements, the function of crankshaft becomes very vital. To understand the reason behind the fatigue and heavy load cycles, a mathematical model is simulated. The complex geometry of crankshaft is developed in a numerical solver. The model is simulated relative to several material properties to mimic the resulting fatigue. The numerical data was optimized using the python Bayesian optimization tools, to forecast the threshold values relative to longer duration. In the recent literature, different nano-composites are acquiring at- tention as the coating materials, to tackle with the friction load. The hybrid modeling approach used during this research can help to simulate the stresses, resulting from dif- ferent nanocomposite coatings.

description: Research focuses on developing a novel flame-retardant filament utilizing acrylonitrile–butadiene–styrene (ABS) and ammonium polyphosphate (APP) by the numerical approach using finite element analysis (FEM)-based software, COMSOL Multiphysics to overcome nozzle clogging and establish optimal three-dimensional (3D)-printing parameters. The developed FEM model enabled the numerical testing of differently shaped nozzles and proven the benefit of using a low-convergence angle (60°) nozzle because of the greater magnitude of pressure drop at nozzle tip compared with that of a high-convergence angle (120°) nozzle, a slightly better temperature distribution at the nozzle region, and smoother flow of the melted filament. Experimental tests results demonstrated the feasibility of using fused filament fabrication 3D printing to apply on ABS composite directly, and the printed samples retain their properties. An improvement in the burning test showed a V 0 rating, thermal stability 13% at 800 °C, and the heat release rate of ∼390 W/g compared with neat ABS (∼501 W/g).

description: We propose an underwater image enhancement algorithm that leverages both model- and learning-based approaches by unfolding an iterative algorithm. We first formulate the underwater image enhancement task as a joint optimization problem, based on the image formation model with physical model and underwater-related priors. Then, we solve the optimization problem iteratively. Finally, we unfold the iterative algorithm so that, at each iteration, the optimization variables and regularizers for image priors are updated by closed-form solutions and learned deep networks, respectively. Experimental results demonstrate that the proposed algorithm outperforms state-of-the-art underwater image enhancement algorithms.

description: Using the approach of low-energy effective field theory, the phase diagram is studied for a mixture of two species of pseudospin-$\1/2$ Bose atoms with interspecies spin-exchange. There are four mean-field regimes on the parameter plane of $g_e$ and $g_z$, where $g_e$ is the interspecies spin-exchange interaction strength, while $g_z$ is the difference between the interaction strength of interspecies scattering without spin-exchange of equal spins and that of unequal spins. Two regimes, with $|g_z| > |g_e|$, correspond to ground states with the total spins of the two species parallel or antiparallel along $z$ direction, and the low energy excitations are equivalent to those of two-component spinless Bosons. The other two regimes, with $|g_e| > |g_z|$, correspond to ground states with the total spins of the two species parallel or antiparallel on $xy$ plane, and the low energy excitations are described by a sine-Gordon model coupled with a free scalar field, where the effective fields are combinations of the phases of the original four Boson fields. In (1+1)-dimension, they are described by Kosterlitz-Thouless renormalization group (RG) equations, and there are three sectors in the phase plane of a scaling dimension and a dimensionless parameter proportional to the strength of the cosine interaction, both depending on the densities. The gaps of these elementary excitations are experimental probes of the underlying many-body ground states.

description: We address distinguishing whether an input is a facial image by learning only a facial-expression recognition (FER) dataset. 
To avoid misclassification in FER, it is necessary to distinguish whether the input is a facial image. Unfortunately, collecting exhaustive nonface images is costly. Therefore, distinguishing whether the input is a facial image by learning only an FER dataset is important. A representative method for this task is learning reconstruction of only facial images and determining high-error samples between input images and reconstructed images as non-face images. 
However, reconstruction is difficult on facial images because such images contain detailed features. Our key idea to tackle the task without reconstruction is assuming that facial images will match several emotions, whereas non-face images will not match any emotion. 
Therefore, we propose a method for training a discriminator that determines whether the inputs and emotions match using counterfactual pairs in an FER dataset. A metric for the task is then obtained by taking into account each emotion in the posterior probability that inputs and emotions match, estimated by the discriminator. 
Experiments on the RAF-DB dataset vs. the Stanford Dogs dataset and AffectNet datasets showed the effectiveness of our method.

Non-Fefferman-Graham asymptotics and holographic renormalization in New Massive Gravity
Creators: name: Cunliff, Colin
Publisher: name: arXiv
Year: 2013
Subjects: subject: High Energy Physics - Theory (hep-th)

description: The asymptotic behavior of new massive gravity (NMG) is analyzed for all values of the mass parameter satisfying the Breitenlohner-Freedman bound. The traditional Fefferman-Graham expansion fails to capture the dynamics of NMG, and new terms in the asymptotic expansion are needed to include the massive graviton modes. New boundary conditions are discovered for a range of values $-1<2m^2l^2<1$ at which non-Einstein modes decay more slowly than the Brown-Henneaux boundary conditions. The holographically renormalized stress tensor is computed for these modes, and the relevant counterterms are identified up to unphysical ambiguities.

description: A new boson with mass ~125 GeV and properties similar to the Standard Model Higgs has been discovered by both the ATLAS and CMS collaborations, with significant observation in the ZZ* to 4 leptons and the diphoton channels. In this work we ask whether the signals in these two channels can be due primarily to two distinct resonances, each contributing dominantly to one channel. We investigate this question in the framework of a 2HDM and several of its extensions. We conservatively find that such a scenario is not possible in a pure 2HDM, nor under the addition of vector-like quarks, but is allowed when adding one or two top-like scalars, if one allows for sub-one tanβ. The resonances in the diboson and diphoton channels can then be two scalars, or a scalar and a pseudoscalar, respectively. In each viable case, we further find the expected future deviations in the diboson, diphoton, b \bar b and tau tau rates, which will be useful in excluding the two-resonance scenario.

description: We address distinguishing whether an input is a facial image by learning only a facial-expression recognition (FER) dataset. 

To avoid misclassification in FER, it is necessary to distinguish whether the input is a facial image. Unfortunately, collecting exhaustive non-face images is costly. Therefore, distinguishing whether the input is a facial image by learning only an FER dataset is important. A representative method for this task is learning reconstruction of only facial images and determining high-error samples between input images and reconstructed images as non-face images. However, reconstruction is difficult on facial images because such images contain detailed features. 

Our key idea to tackle the task without reconstruction is assuming that facial images will match several emotions, whereas non-face images will not match any emotion. Therefore, we propose a method for training a discriminator that determines whether the inputs and emotions match using counterfactual pairs in an FER dataset. A metric for the task is then obtained by taking into account each emotion in the posterior probability that inputs and emotions match, estimated by the discriminator. 

Experiments on the RAF-DB dataset vs. the Stanford Dogs dataset and AffectNet datasets showed the effectiveness of our method.

description: This paper investigates the MaxRS problem in spatial databases. Given a set O of weighted points and a rectangular region r of a given size, the goal of the MaxRS problem is to find a location of r such that the sum of the weights of all the points covered by r is maximized. This problem is useful in many location-based applications such as finding the best place for a new franchise store with a limited delivery range and finding the most attractive place for a tourist with a limited reachable range. However, the problem has been studied mainly in theory, particularly, in computational geometry. The existing algorithms from the computational geometry community are in-memory algorithms which do not guarantee the scalability. In this paper, we propose a scalable external-memory algorithm (ExactMaxRS) for the MaxRS problem, which is optimal in terms of the I/O complexity. Furthermore, we propose an approximation algorithm (ApproxMaxCRS) for the MaxCRS problem that is a circle version of the MaxRS problem. We prove the correctness and optimality of the ExactMaxRS algorithm along with the approximation bound of the ApproxMaxCRS algorithm. From extensive experimental results, we show that the ExactMaxRS algorithm is two orders of magnitude faster than methods adapted from existing algorithms, and the approximation bound in practice is much better than the theoretical bound of the ApproxMaxCRS algorithm.

Feature integration via back-projection orderingmulti-modal Gaussian process latent variable modelfor rating prediction
Publisher: name: IEEE Signal Processing Society
Year: 2023

description: In this paper, we present a method of feature integration via backprojection ordering multi-modal Gaussian process latent variable model (BPomGP) for rating prediction. In the proposed method, to extract features reflecting the users’ interest, we use the known ratings assigned to the viewed contents and users’ behavior information while viewing the contents which is related to the users’ interest. BPomGP has two important approaches. Unlike the training phase, where the above two types of heterogeneous information are available, behavior information is not given in the test phase. Thus, the projection that transforms content features into integrated features is trained by using both content and behavior features. Furthermore, to reflect the unique characteristics of ratings, their ordering, we constrain the distance between integrated features in a latent space based on the difference in the degree of known ratings. Finally, experimental results show that the proposed method can calculate features that are useful for rating prediction.

description: The VLBI Global Observing System (VGOS) for geodesy and astrometry has been in operation for several years. However, many of the sources of the International Celestial Reference Frame (ICRF3) still have poorly known radio flux densities in the currently observed VGOS frequency bands. To improve the efficiency of observation scheduling, an accurate flux density catalog is urgently needed.

We present the results of flux monitoring experiments performed with the Onsala Twin Telescopes (OTT) on a rather regular basis since June 2021. The telescopes have a diameter of 13.2 m and are located at Onsala, Sweden, forming an interferometer with a baseline of 75 m distance. We present time series of flux density in the standard VGOS bands that are used so-far for the VGOS Operational (VO) sessions, i.e. 3.0–3.5 GHz, 5.2–5.7 GHz, 6.3–6.8 GHz and 10.2–10.7 GHz, for over 200 sources, most of which are defining sources of the ICRF3. The first set of flux monitoring experiments, conducted between June and December 2021, were a pilot study focusing on seven radio sources from the standard VGOS catalog and three calibrators (3C147, 3C286 and 3C295). Later experiments extended the source list to all ICRF3 defining sources, of which approximately 200 are visible from Onsala. In addition to these dedicated flux monitoring experiments with the OTT, we also analysed OTT data from several VO sessions. These VO observations have been calibrated by adding calibrator scans with the OTT to the end of the VO-schedules.

 All data were analyzed using Common Astronomy Software Applications (CASA). Due to local radio frequency interference at Onsala, few radio sources have reliable flux density values in the lowest VO-band (3.0–3.5 GHz). Also VO-band-2 (5.2–5.7 GHz) is somewhat affected by disturbing interference. Most sources are found to be variable over time. We estimate an uncertainty of 5 % for our flux density results. In the future, we plan to extend the method to include other stations, allowing to obtain flux densities for longer baselines as well.

Clebsch variational principles in field theories and singular solutions of covariant EPDiff equations
Creators: name: Gay-Balmaz, François
Publisher: name: arXiv
Year: 2012
Subjects: subject: Mathematical Physics (math-ph)
subject: FOS: Physical sciences

description: This paper introduces and studies a field theoretic analogue of the Clebsch variational principle of classical mechanics. This principle yields an alternative derivation of the covariant Euler-Poincaré equations that naturally includes covariant Clebsch variables via multisymplectic momentum maps. In the case of diffeomorphism groups, this approach gives a new interpretation of recently derived singular peakon solutions of Diff(R)-strand equations, and allows for the construction of singular solutions (such as filaments or sheets) for a more general class of equations, called covariant EPDiff equations. The relation between the covariant Clebsch principle and other variational principles arising in mechanics and field theories, such as Hamilton-Pontryagin principles, is explained through the introduction of a class of covariant Pontryagin variational principles in field theories.

Publisher: name: IEEE Signal Processing Society

description: In this paper, the Multi-view Variational Recurrent Neural Network (MvVRNN) is proposed for multi-modal human emotion recognition with gaze and brain activity data while humans view images. For realizing accurate emotion recognition, we focus on the following three characteristics of biological signals: 1) the relationship between implicit and explicit information such as gaze and brain activity data, 2) the temporal changes related to human emotions and 3) the effects of noises that can be included during data acquisition. For treating these characteristics, the proposed MvVRNN has several mechanisms including 1) the integration of multi-modal information including implicit and explicit states of humans, 2) the recurrent module for sequential data and 3) the variational approximation based on the Gaussian distribution. The experimental results show that emotion recognition based on the MvVRNN outperforms several existing methods.

description: We investigate the geometric properties of marginally trapped surfaces (surfaces which have null mean curvature vector) in the spaces of oriented geodesics of Euclidean 3-space and hyperbolic 3-space, endowed with their canonical neutral Kaehler structures. We prove that every rank one surface in these four manifolds is marginally trapped. In the Euclidean case we show that Lagrangian rotationally symmetric sections are marginally trapped and construct an explicit family of marginally trapped Lagrangian tori. In the hyperbolic case we explore the relationship between marginally trapped and Weingarten surfaces, and construct examples of marginally trapped surfaces with various properties.

description: AKLT state (or Haldane phase) in a spin-1 chain represents a large class of gapped topological paramagnets, which hosts symmetry-protected gapless excitations on the boundary. In this work we show how to realize this type of featureless spin-1 states on a generic two-dimensional lattice. These states have a gapped spectrum in the bulk but supports gapless edge states protected by spin rotational symmetry along a certain direction, and are featured by spin quantum Hall effect. Using fermion representation of integer-spins we show a concrete example of such spin-1 topological paramagnets on kagome lattice, and suggest a microscopic spin-1 Hamiltonian which may realize it.

description: The synergy between the Fermi-LAT and ground-based Cherenkov telescope arrays gives us the opportunity for the first time to characterize the high-energy emission from blazars over 5 decades in energy, from 100 MeV to 10 TeV. In this study, we perform a Fermi-LAT spectral analysis for TeV-detected blazars and combine it with archival TeV data. We examine the observational properties in the gamma-ray band of our sample of TeV-detected blazars and compare the results with X-ray and GeV-selected populations. The spectral energy distributions (SEDs) that result from combining Fermi-LAT and ground-based spectra are studied in detail. Simple parameterizations such as a power-law function do not always reproduce the high-energy SEDs, where spectral features that could indicate intrinsic absorption are observed.

SANDWICHED VIDEO COMPRESSION: EFFICIENTLY EXTENDING THE REACH OF STANDARD CODECS WITH NEURAL WRAPPERS
Publisher: name: IEEE Signal Processing Society
Year: 2023

description: We propose sandwiched video compression – a video compression
system that wraps neural networks around a standard video codec.
The sandwich framework consists of a neural pre- and post-processor
with a standard video codec between them. The networks are trained
jointly to optimize a rate-distortion loss function with the goal of significantly improving over the standard codec in various compression
scenarios. End-to-end training in this setting requires a differentiable
proxy for the standard video codec, which incorporates temporal
processing with motion compensation, inter/intra mode decisions,
and in-loop filtering. We propose differentiable approximations to
key video codec components and demonstrate that, in addition to
providing meaningful compression improvements over the standard
codec, the neural codes of the sandwich lead to significantly better rate-distortion performance in two important scenarios. When
transporting high-resolution video via low-resolution HEVC, the
sandwich system obtains 6.5 dB improvements over standard HEVC.
More importantly, using the well-known perceptual similarity metric,
LPIPS, we observe 30% improvements in rate at the same quality
over HEVC. Last but not least, we show that pre- and post-processors
formed by very modestly-parameterized, light-weight networks can
closely approximate these results
