description: The shadow of a black hole or a collapsing star is of great importance as we can extract important properties of the object and of the surrounding spacetime from the shadow profile. It can also be used to distinguish different types of black holes and ultra compact objects. In this work, we have analytically calculated the shadow of a higher dimensional collapsing dark star, described by higher dimensional Vaidya metric, by choosing a slightly generalized version of Misner--Sharp mass function. We have also numerically investigated the properties of the shadows of the black holes and the collapsing stars for a slightly more general mass function. Examining the potential influence of extra spatial dimensions on the shadow, we have explored the possibility of distinguishing higher dimensions from the standard four-dimensional spacetime.

description: We illustrate the solution of a mixed-integer stochastic nonlinear optimization problem in an application of power management. In this application, a coupled system consisting of a hydro power station and a wind farm is considered. The objective is to satisfy the local energy demand and sell any surplus energy on a spot market for a short time horizon. Generation of wind energy is assumed to be random, so that demand satisfaction is modeled by a joint probabilistic constraint taking into account the multivariate distribution. The turbine is forced to either operate between given positive limits or to be shut down. This introduces additional binary decisions. The numerical solution procedure is presented and results are illustrated.

description: Starting from the two-particle Bethe-Salpeter equation in the ladder approximation and integrating over the time component of momentum, we rederive three dimensional scattering integral equations satisfying constraints of relativistic unitarity and covariance, first derived by Weinberg and by Blankenbecler and Sugar. These two-particle equations are shown to be related by a transformation of variables. Hence we show how to perform and relate identical dynamical calculation using these two equations. Similarly, starting from the Bethe-Salpeter-Faddeev equation for the three-particle system and integrating over the time component of momentum, we derive several three dimensional three-particle scattering equations satisfying constraints of relativistic unitarity and covariance. We relate two of these three-particle equations by a transformation of variables as in the two-particle case. The three-particle equations we derive are very practical and suitable for performing relativistic scattering calculations.

description: Using a local moment approach of Logan et al. we developed a solver for a multi-orbital single impurity Anderson model. The existence of the local moments is taken from the outset and their values are determined through variational principle by minimizing the corresponding ground state energy. The method is used to solve the dynamical mean-field equations for the multi-orbital Hubbard model. In particular, the Mott-Hubbard metal--insulator transition is addressed within this approach.

description: Improving speech system performance in noisy environments remains a challenging task, and speech enhancement (SE) is one of the effective techniques to solve the problem. Motivated by the promising results of generative adversarial networks (GANs) in a variety of image processing tasks, we explore the potential of conditional GANs (cGANs) for SE, and in particular, we make use of the image processing framework proposed by Isola et al. [1] to learn a mapping from the spectrogram of noisy speech to an enhanced counterpart. The SE cGAN consists of two networks, trained in an adversarial manner: a generator that tries to enhance the input noisy spectrogram, and a discriminator that tries to distinguish between enhanced spectrograms provided by the generator and clean ones from the database using the noisy spectrogram as a condition. We evaluate the performance of the cGAN method in terms of perceptual evaluation of speech quality (PESQ), short-time objective intelligibility (STOI), and equal error rate (EER) of speaker verification (an example application). Experimental results show that the cGAN method overall outperforms the classical short-time spectral amplitude minimum mean square error (STSA-MMSE) SE algorithm, and is comparable to a deep neural network-based SE approach (DNN-SE).

description: This project examines the various roles of mobile-clad citizen witnesses of crisis as well as how their produced content is used in the news, based on a critical discourse analysis of 140 tweets shared during the first week of Nicaragua’s current socio-political crisis. This corpus was developed through data cleaning to include only those shared by news organizations that showcased citizen visuals. The analysis showed that citizen witnesses enacted four distinguishable roles: that of verifier, watchdog, unifier, and dissenter, and that news organizations tended to incorporate citizen content through re-tweeting with no added context

description: Any sports competition needs a timetable, specifying when and where teams meet each other. The recent International Timetabling Competition (ITC2021) on sports timetabling showed that, although it is possible to develop general algorithms, the performance of each algorithm varies considerably over the problem instances. This paper provides an instance space analysis for sports timetabling, resulting in powerful insights into the strengths and weaknesses of eight state-of-the-art algorithms. Based on machine learning techniques, we propose an algorithm selection system that predicts which algorithm is likely to perform best when given the characteristics of a sports timetabling problem instance. Furthermore, we identify which characteristics are important in making that prediction, providing insights in the performance of the algorithms, and suggestions to further improve them. Finally, we assess the empirical hardness of the instances. Our results are based on large computational experiments involving about 50 years of CPU time on more than 500 newly generated problem instances.

description: We study Born-Infeld strings in a six dimensional brane world scenario recently suggested by Giovannini, Meyer and Shaposhnikov (GMS). In the limit of the Einstein-Abelian-Higgs model, we classify the solutions found by GMS. Especially, we point out that the warped solutions, which lead to localisation of gravity, are the - by the presence of the cosmological constant - deformed inverted string solutions. Further, we construct the Born-Infeld analogues of the anti-warped solutions and determine the domain of existence of these solutions, while a analytic argument leads us to a "no-go" hypothesis: solutions which localise gravity do NOT exist in a 6 dimensional Einstein-Born-Infeld-Abelian-Higgs (EBIAH) brane world scenario. This latter hypothesis is confirmed by our numerical results.

description: This article is devoted to the modeling of elastic materials composed by an incompressible elastic matrix and small compressible gaseous inclusions, under a time harmonic excitation. In a biomedical context, this model describes the dynamics of a biological tissue (e.g. lung or liver) when wave analysis methods (such as Magnetic Resonance Elastography) are used to estimate tissue properties. Due to the multiscale nature of the problem, direct numerical simulations are prohibitive. We extend the homogenized model introduced in [Baffico, Grandmont, Maday, Osses, SIAM J. Mult. Mod. Sim., 7(1), 2008] to a time harmonic regime to describe the solid-gas mixture from a macroscopic point of view in terms of an effective elasticity tensor. Furthermore, we derive and validate numerically analytical approximations for the effective elastic coefficients in terms of macroscopic parameters. This simplified description is used to to set up an efficient variational approach for the estimation of the tissue porosity, using the mechanical response to external harmonic excitations.

description: The lattice Boltzmann method (LBM) is emerging as a powerful engineering tool for aeroacoustic computations. However, the LBM has been shown to present accuracy and stability issues in the medium-low Mach number range, that is of interest for aeroacoustic applications. Several solutions have been proposed but often are too computationally expensive, do not retain the simplicity and the advantages typical of the LBM, or are not described well enough to be usable by the community due to proprietary software policies. We propose to use an original regularized collision operator, based on the expansion in Hermite polynomials, that greatly improves the accuracy and stability of the LBM without altering significantly its algorithm. The regularized LBM can be easily coupled with both non-reflective boundary conditions and a multi-level grid strategy, essential ingredients for aeroacoustic simulations. Excellent agreement was found between our approach and both experimental and numerical data on two different benchmarks: the laminar, unsteady flow past a 2D cylinder and the 3D turbulent jet. Finally, most of the aeroacoustic computations with LBM have been done with commercial softwares, while here the entire theoretical framework is implemented on top of an open source library (Palabos).

description: A six-year study was conducted to compare the prevalence of cataract in Kottayam and Pathanamthitta in Kerala state, India. From April 2005 to March 2011, a hospital-based study was performed to determine the prevalence of cataracts in the overall population, gender prevalence, and prevalence in different age groups. The information was gathered from the ophthalmology departments of district hospitals and two private hospitals in Pathanamthitta and Kottayam districts, as well as the Directorate of Health, Thiruvananthapuram. The burden of blind is more in remote rural community of developing countries. With three out of every four Indians residing in the rural areas, there is a concentration of blindness in agriculture dependent communities in India. Cataract prevalence among the total population in Kottayam district was significantly increased from 0.34% to 0.51% (p=0.000157), but in Pathanamthitta district prevalence significantly decreased from 0.40 % to 0.36% (p=0.0024). Gender prevalence is significantly higher in females in Kottayam (61.6%, 0.0000326) as well as in Pathanamthitta (59%, 0.00014) than in males, suggest that females have more cataract. A significantly highest prevalence recorded in the age group of 71-80 years in Kottayam (36.6%, 0.000072) and Pathanamthitta (33.6%, 0.000312) as compared with all other age groups. Prevalence of congenital cataract (0-15) is very less in Kottayam (1.2%) and Pathanamthitta(0.9%). The decrease in the prevalence rate in Pathanamthitta district is attributed to a decrease in the population.Only by developing effective strategies to low the incidence of blinding cataract can cataract blindness in Kerala be effectively managed. The current analysis of cataract prevalence in Kerala may shed light on the severity of cataract incidence in the state to some extent.

description: We study non-isothermal nucleation and growth phase transformations, which are described by a generalized Avrami model for the phase transition coupled with an energy balance to account for recalescence effects. The main novelty of our work is the identification of temperature dependent nucleation rates. We prove that such rates can be uniquely identified from measurements in a subdomain and apply an optimal control approach to develop a numerical strategy for its computation.

description: Third-generation gravitational wave (GW) observatories such as the Einstein Telescope and Cosmic Explorer, together with the LSST survey at the Vera Rubin Observatory, will yield an abundance of extra-galactic transient objects. This opens the exciting possibility of using GW sources and Supernovae Type Ia (SNIa) as luminosity distance tracers of large-scale structure for the first time. The large volumes accessible to these surveys imply that we may need to include relativistic corrections, such as lensing and Doppler magnification. However, the amplitude of these effects depends on the magnification and evolution biases of the transient sources, which are not yet understood. In this paper we develop comprehensive frameworks to address and model these biases for both populations of transient objects; in particular, we define how to compute these biases for GW sources. We then analyse the impact of magnification and evolution biases on the relativistic corrections and on the angular power spectrum of these sources. We show that correct modelling and implementation of these biases is crucial for measuring the cross-correlations of transient sources at higher redshifts.

This polarization has been calculated in the one-loop approximation but summed up to all orders (RPA-type calculation). This effect is found to be rather important but does not improve the agreement with experiment.

description: Climate change — or long-term changes in the Earth’s climate — is a highly debated topic of conversation in modern society. Widely discussed in political arenas and in the media, climate change is still relatively new as a topic taught in schools. In Texas, teachers face a number of obstacles to educating their students about climate change and its impacts. These barriers include — but are not limited to — a lack of personal knowledge on the subject, a fear that they will be accused of advancing a political agenda, the complexity of the topic and a lack of state education standards around climate change. This is the environment teachers such as Nina Corley, in Galveston, and Melissa Michalak, in Helotes, navigate as they cover the highly politicized topic. These teachers, just two among thousands, each have their own approach to covering the material, but both strongly believe the subject needs to be taught

description: We reconsider the long-standing problem of the effect of spin fluctuations on the critical temperature and isotope effect in a phonon-mediated superconductor. Although the general physics of the interplay between phonons and paramagnons had been rather well understood, the existing approximate formulas fail to describe the correct behavior of $% T_{c}$ for general phonon and paramagnon spectra. Using a controllable approximation, we derive an analytical formula for $T_{c}$ which agrees well with exact numerical solutions of the Eliashberg equations for a broad range of parameters. Based on both numerical and analytical results, we predict a strong enhancement of the isotope effect when the frequencies of spin fluctuation and phonons are of the same order. This effect may have important consequences for near-magnetic superconductors such as MgCNi$_{3}$

description: When string theory is compactified on a six-dimensional manifold with a nontrivial NS flux turned on, mirror symmetry exchanges the flux with a purely geometrical composite NS form associated with lack of integrability of the complex structure on the mirror side. Considering a general class of T^3-fibered geometries admitting SU(3) structure, we find an exchange of pure spinors (e^{iJ} and Ω) in dual geometries under fiberwise T-duality, and study the transformations of the NS flux and the components of intrinsic torsion. A complementary study of action of twisted covariant derivatives on invariant spinors allows to extend our results to generic geometries and formulate a proposal for mirror symmetry in compactifications with NS flux.

description: Silicon metal-oxide-semiconductor field effect transistors (MOSFETs) fabricated on a SIMOX (001) substrate, which is a kind of silicon on insulator (SOI) substrate, that is annealed at high temperature for a long time are known to exhibit large valley splitting, but the origin of this splitting has long been unknown. Extended zone effective-mass approximation (EMA) predicts that strain significantly affects valley splitting. In this study, we analyzed valley splitting based on this theory and found that the shear strain along <110> of approximately 5% near the buried oxide (BOX) interface is a promising source for large valley splitting.

description: Group-velocity matched cross-phase modulation between a fundamental soliton and a dispersive wave-packet has been previously suggested for optical switching applications similar to an optical transistor. Moreover, the nonlinear interaction in the resulting groupvelocity horizon can be exploited for adiabatic compression of the soliton down into the fewcycle regime. Here we show that both mechanisms can be combined. In such a transient compressor, parameters of the dispersive wave may then serve to actively control the soliton compression and adjust the pulse duration in the presence of disturbances. While a certain amount of control is already enabled by the delay between soliton and dispersive wave, the means of controlling the compression process are substantially enhanced by additionally manipulating the chirp of the dispersive wave. Moreover, controlling the chirp of the dispersive wave also enables correction for limitations of the compression scheme due to a self-frequency shift of the soliton or for uncompensated dispersion in the scheme. This substantially widens the practicality of the compression scheme and other applications of the highly efficient nonlinear interaction at the group-velocity horizon.

description: This paper applies a recently developed geometric PID controller to stabilize a three-link planar bipedal hybrid dynamic walking model. The three links represent the robot torso and two kneeless legs, with an independent control torque available at each hip joint. The geometric PID controller is derived for fully actuated mechanical systems, however in the swing phase the three-link biped robot has three degrees of freedom and only two controls. Following the bipedal walking literature, underactuation is addressed by choosing two "virtual constraints" to enforce, and verifying the stability of the resulting two-dimensional zero dynamics. The resulting controlled dynamics do not have the structure of a mechanical system, however this structure is restored using "feedback regularization," following which geometric PID control is used to provide robust asymptotic regulation of the virtual constraints. The proposed method can tolerate significantly greater variations in inclination, showing the value of the geometric methods, and the benefit of integral action.

We focus on the number of omitted values and the total weight of the totally ramified values of their Gauss maps. In particular, we construct new complete minimal surfaces of finite total curvature whose Gauss maps have 2 omitted values and 1 totally ramified value of order 2, that is, the total weight of the totally ramified values of their Gauss maps are 5/2 (=2.5) in Euclidean 3-space and Euclidean 4-space, respectively. Moreover we discuss several outstanding problems in this study.

description: Vitamins are the organic compounds essential for normal growth and metabolic processes in all living organisms. B vitamins, such as vitamin B9 and B12, act as cofactors in various metabolic reactions, including one-carbon (1C) metabolism, and typically are required in trace amounts. The gut harbors a diverse population of bacteria, some of which are capable of producing certain vitamins. These bacteria also require vitamins for their growth and proliferation, with requirements varying between vitamin-producing and non-producing strains. However, bacterially synthesized vitamins are limited, and dietary intake is vital for meeting the host’s daily requirements. Despite the well-understood functional role of B vitamins, their precise impacts on gut ecology remains poorly understood. The current study aimed to investigate the impacts of vitamin B9 and B12 deficiencies on gut morphology, microbial composition, and their metabolites using a rodent model of vitamin deficiency. Our findings revealed that a deficiency in vitamin B9 or B12 altered mucosal height and decreased acidic mucin production in the colon. Of particular interest, we observed sex-dependent differences in the effects of vitamin deficiency on the gut microbial profile. The analysis of fecal metabolites showed notable alterations in metabolites associated with gut health in the vitamin-deficient groups compared to the control. This study provides evidence that deficiencies in B vitamins, particularly those involved in 1C metabolism, can disturb gut homeostasis in a sex-dependent manner.

description: Using a system of two FitzHugh-Nagumo units, we demonstrate the occurrence of riddled basins of attraction in delay-coupled systems as the coupling between the units is increased. We characterize the riddled basin using the uncertainty exponent which is a measure of the dimensions of the basin boundary. Additionally, we show that the phase space can be partitioned into pure and mixed regions, where initial conditions in the pure regions certainly avoid the generation of extreme events while initial conditions in the mixed region may or may not exhibit such events. This implies, that any tiny perturbation of initial conditions in the mixed region could yield the emergence of extreme events because the latter state possesses a riddled basin of attraction.

description: This report explores racial tensions among city leaders and residents in Crockett, Texas, a city in the rural and heavily conservative eastern region of the state, resulting from a petition created by the city’s white mayor to abolish the city’s economic development corporation, headed by its first black executive director. Many residents’ negative perception of the mayor is exacerbated by her status as the county’s Republican Party chair, her vocal support of President Donald Trump, her alleged discriminatory treatment of employees at the restaurant she owns and a pair of photos taken at her restaurant that many residents believe are racist

description: The high-temperature aspects of the Casimir force between two neutral conducting walls are studied. The mathematical model of "inert" ideal-conductor walls, considered in the original formulations of the Casimir effect, is based on the universal properties of the electromagnetic radiation in the vacuum between the conductors, with zero boundary conditions for the tangential components of the electric field on the walls. This formulation seems to be in agreement with experiments on metallic conductors at room temperature. At high temperatures or large distances, at least, fluctuations of the electric field are present in the bulk and at the surface of a particle system forming the walls, even in the high-density limit: "living" ideal conductors. This makes the enforcement of the inert boundary conditions inadequate. Within a hierarchy of length scales, the high-temperature Casimir force is shown to be entirely determined by the thermal fluctuations in the conducting walls, modelled microscopically by classical Coulomb fluids in the Debye-Hückel regime. The semi-classical regime, in the framework of quantum electrodynamics, is studied in the companion letter by P.R.Buenzli and Ph.A.Martin, cond-mat/0506363, Europhys.Lett.72, 42 (2005).

description: Background: More than 50% of people aged 40 years suffer from cervicarthrosis, This disease constitutes a public health problem. For this the decade 2001-2010 was declared by the WHO as “decade of the bones and joints”. Objective: To determine the epidemiological and clinical profile of the Congolese patients suffering about cervical arthrosis and to study the evolution of modification of cervical lordosis with a view to improving physical treatment. Methods: This case study was conducted at the University clinics of Kinshasa during the year 2011 to 2016. 35 patients’ male and female, suffering about cervical arthrosis, were included. The different angulations of the cervical lordosis measured with an appropriate software. The height of the cervical spine measured by a caliper was 14 cm on average. The load exerted by the head on the cervical spine is directly function of lordosis and the height of the vertebra was calculated. Results: Of the 35 patients, 34.3% men and 65.7 women. Age ranged from 30 to 80 years and the highest incidence of cervicarthrosis was between 61 and 65 years (20%). The clinic was dominated by cervical pain (80%) and irradiated pain in 37%. Other signs (blurred vision, headache, dizziness) were poorly represented. For radiographic signs: cervical lordosis was eliminated either decreased in 91% of cases, followed by inter-somatic pinching (68%), ductal stenosis (62%) and osteophytosis in only 20% of cases. However, osteoarthritic myelopathy is extremely rare (2%). Variation of the head load (in Kg) on each vertebra of the cervical spine from C1 to C7 and from 0 to 45° depending on the level of the vertebra and the degree of cervical lordosis. The force increases from C1 to C7 and from 45° to 0° following an arithmetic progression. Conclusion: This chapter has just highlighted the importance of the cervical lordosis spine in the diagnosis of cervical arthrosis and showed the important role of cervical lordosis in the variation of head load on each vertebra. Cervical arthritis is a severe degenerative disease that affects the cervical region.

description: Grain boundaries can dissociate into facets if that reduces their excess energy. This, however, introduces line defects at the facet junctions, which present a driving force to grow the facets in order to reduce the total number of junctions and thus the system's energy. Often, micrometer-sized facet lengths are observed and facet growth only arrests for kinetic reasons. So far, energetically stable, finite-sized facets have not been observed, even though theoretical stability conditions have already been proposed. Here, we show a case where nanometer-sized facets are indeed stable compared to longer facets in [111] tilt grain boundaries in Cu by atomistic simulation and transmission electron microscopy. The facet junctions lack a Burgers vector component, which is unusual, but which removes the main energy cost of facet junctions. Only attractive interactions via line forces remain, which result from a discontinuity of grain boundary excess stress at the junction. Atomistic simulations predict that the same phenomenon also occurs in at least Al and Ag.

Newsroom diversity

description: This dissertation focuses on the trust relationship in the newsroom to examine journalists’ status-based homophily, which refers to an individual’s tendency that similarity in social statuses breeds informal connection at work. It analyzes South Korean newspapers as a case study because their newsroom composition has become diverse and intergroup relationships emerged as a key issue for newsroom management. Trust at work serve facilitates knowledge, information, and the skill set relevant to organizational survival. However, trust is not shared by everyone because status-based homophily governs the informal relationship. In particular, separated informal relationships between the majority with power and control and minority groups lead to the following research question of “which social characteristics of individuals that represent a symbol of social statuses at work generate homophily in journalists’ trust?” To answer this research question, the author incorporated network homophily and social identity theory as main theoretical frameworks and employed inferential network analysis with the Exponential Random Graph Model (ERGM) as a primary methodological approach. Considering the unique nature of local characteristics in South Korea, the author assesses five social statuses on South Korean journalists’ homophilous tendency in their trust network: (1) gender, (2) tenure, (3) academic prestige (4) recruitment, and (5) competence. In particular, a separate empirical analysis on two cases of the South Korean newspapers verifies whether status-based homophily is consistently found across the newspapers with different cultures and organizational composition. The inferential network analysis of ERGM identified tenure-based homophily for both newspapers, while recruitment-based homophily and competence-based homophily were only found in one of the newspapers. Gender-based homophily became statistically insignificant as additional status-based homophily terms were added, which shows its relative weakness in determining journalists’ homophilous tendency compared to other status-based homophily terms. Academic prestige-based homophily was not found to be significant for both newspapers. This dissertation will add more insight into the theoretical adaptation of the social network theory and its association with the journalism practice inside the newsroom. Primarily, newsroom managers will learn a practical implication of how to manage the growing diversity inside the newsroom to unlock the positive effect of diversity.

description: In this talk, we review the instability due to radiatively induced FI tadpoles in ${\cal N}=2$ supersymmetric gauge theories on orbifolds in six dimensions. Even with the localized FI tadpoles, we have the unbroken supersymmetry at the expense of having the spontaneous localization of bulk zero mode. We find the non-decoupling of massive modes unlike the 5D case. We also comment on the local anomaly cancellation.
