description: We examine a class of cylindrically symmetric solutions in Horava-Lifshitz gravity. For the relativistic value of the coupling constant, $ λ=1 $, we find the "hedgehog" type static black string solution with the nonvanishing radial shift in the ADM-type decomposition of the spacetime metric. With zero radial shift, this solution corresponds to the usual BTZ black string in general relativity. However, unlike the general relativity case, the BTZ type black strings do naturally exist in HL gravity, without the need for any specific source term. We also find a rotating BTZ type black string solution which requires the nonvanishing radial shift for its very existence. We calculate the mass and the angular momentum of this solution, using the canonical Hamiltonian approach. Next, we discuss the Lemos type black string, which is inherent in general relativity with a negative cosmological constant, and present the static metric for any value of $ λ> 1/3 $. Finally, we show that while, for $λ=1 $, the entropy of the Lemos type black string is given by one quarter of the horizon area, the entropy of the static BTZ type black string is one half of its horizon area.

description: We consider the large time behavior in two types of equations, posed on the whole space R^d: the Schr{ö}dinger equation with a logarithmic nonlinearity on the one hand; compressible, isothermal, Euler, Korteweg and quantum Navier-Stokes equations on the other hand. We explain some connections between the two families of equations, and show how these connections may help having an insight in all cases. We insist on some specific aspects only, and refer to the cited articles for more details, and more complete statements. We try to give a general picture of the results, and present some heuristical arguments that can help the intuition, which are not necessarily found in the mentioned articles.

On the sideways expansion of relativistic non-spherical shocks and GRB afterglows

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: Expansion of non-spherical relativistic blast waves is considered in the Kompaneets (the thin shell) approximation. We find that the relativistic motion effectively "freezes out" the lateral dynamics of the shock front: only extremely strongly collimated shocks, with the opening angles $Δθ\leq 1/Γ^2$, show appreciable modification of profiles due to sideways expansion. For less collimated profiles the propagation is nearly ballistic; the sideways expansion of relativistic shock becomes important only when they become mildly relativistic.

description: We propose a new framework for Conley index theory. The main feature of our approach is that we do not use the notion of index pairs. We introduce, instead, the notions of compactifiable subsets and index neighbourhoods, and formulate and prove basic results in Conley index theory using these notions. We treat both the discrete time case and the continuous time case.

Nonlinear phonological analysis in assessment of phonological development in Tagalog
Creators: name: Lim, Rachelle Kay
Publisher: name: University of British Columbia
Year: 2014

description: Nonlinear phonological theories emphasize a hierarchical and multi-tiered representation, which describe all aspects of a phonological system. In terms of clinical application, a client's system-wide strengths and needs can be evaluated, and, where necessary, addressed through intervention (Bernhardt, 1992). The population of Tagalog-speaking individuals outside the Philippines is increasing, yet research regarding the language is limited, placing clinicians in a difficult situation during the assessment and treatment of Tagalog-speaking children. This paper aims to bridge the gap by creating a Nonlinear Phonological Scan Analysis (Tagalog) in conjunction with a Tagalog word list, in order to allow clinicians to evaluate a child’s phonological system. The full Tagalog word list (109 words) consists of three separate sets, each containing words with different characteristics (e.g., Extension A contains multisyllabic words, Extension B includes mainly disyllabic words). In order to evaluate the word sets and analysis method, the word list was administered to a 4-year-old child who primarily speaks Tagalog in a picture-naming activity on the computer. The same list was administered to the child’s mother, whose pronunciations then served as the adult targets for analysis. The child’s productions were recorded, transcribed and analyzed quantitatively and qualitatively using the Scan Analysis (Tagalog), which was adapted from the English version (Bernhardt & Stemberger, 2000). Data collected from the child exhibited some similarities and differences in terms of expected patterns from both monolinguals and bilinguals. The child showed evidence of typical development due to the high matches for different evaluations of prosodic structure (e.g. word length, word shape). On the other hand, he exhibited difficulties with whole word, word stress and vowel matches, /r/ and clusters involving /r, l/. Difficulties were suggested to be a result of the child’s Tagalog-English bilingual environment or because of the balance of the word list in terms of /r/ targets, a phoneme which he had not yet mastered. This paper provide some initial steps toward understanding phonological development of typically developing Tagalog-speaking children in a bilingual context outside the Philippines, and by extension, as a basis for future research with children with typical and protracted phonological development.

description: We study the effect of laser phase noise on the generation of stationary entanglement between an intracavity optical mode and a mechanical resonator in a generic cavity optomechanical system. We show that one can realize robust stationary optomechanical entanglement even in the presence of non-negligible laser phase noise. We also show that the explicit form of the laser phase noise spectrum is relevant, and discuss its effect on both optomechanical entanglement and ground state cooling of the mechanical resonator.

description: Recent technological advancements have enabled strong light-matter interaction in highly dissipative cavity-emitter systems. However, in these systems, which are well described by the Tavis-Cummings model, the considerable loss rates render the realization of many desirable nonlinear effects, such as saturation and photon blockade, problematic. Here we present another effect occurring within the Tavis-Cummings model: a nonlinear response of the cavity for resonant external driving of intermediate strength, which makes use of large cavity dissipation rates. In this regime, $(N+1)$-photon processes dominate when the cavity couples to $N$ emitters. We explore and characterize this effect in detail, and provide a picture of how the effect occurs due to destructive interference between the emitter ensemble and the external drive. We find that a central condition for the observed effect is large cooperativity, i.e., the product of the cavity and emitter decay rates is much smaller than the collective cavity-emitter interaction strength squared. Importantly, this condition does not require strong coupling. We also find an analytical expression for the critical drive strength at which the effect appears. Our results have potential for quantum state engineering, e.g., photon filtering, and could be used for the characterization of cavity-emitter systems where the number of emitters is unknown. In particular, our results open the way for investigations of unique quantum-optics applications in a variety of platforms that neither require high-quality cavities nor strong coupling.

description: We consider the nonlinear Schr{ö}dinger equation with a harmonic potential in the presence of two combined energy-subcritical power nonlinearities. We assume that the larger power is defocusing, and the smaller power is focusing. Such a framework includes physical models, and ensures that finite energy solutions are global in time. We address the questions of the existence and the orbital stability of the set of standing waves. Given the mathematical features of the equation (external potential and inhomogeneous nonlinearity), the set of parameters for which standing waves exist in unclear. In the twodimensional case, we adapt the method of fundamental frequency solutions, introduced by the second author in the higher dimensional case without potential. This makes it possible to describe accurately the set of fundamental frequency standing waves and ground states, and to prove its orbital stability.

description: Canadian labour’s position at the beginning of the First World War was weak in relation to employers. Labour reacted to the outbreak of war with enthusiasm, like the rest of Canada. The economic depression that racked the country in 1914 did not end until 1916, as the war orders helped to bolster the Canadian economy. In response to conscription and a lack of workers’ rights, labour engaged in a revolt against employers, the war, and the federal government. The increasing radicalization of labour led to the violent Winnipeg General Strike in June 1919. The national repression of labour radicals followed in the aftermath.

description: Abstract: The European Union's ambitious energy transition necessitates a highly flexible electricity system to accommodate the increasing share of variable renewable energy sources. Electric vehicles (EVs), with their substantial battery storage capacity, present a significant opportunity to provide this flexibility. This article analyzes the potential of EVs as a flexibility resource within the framework of the EU's Electricity Market Directive 2019/944. It explores the technical and economic aspects of EV integration, including smart charging and vehicle to-grid (V2G) technologies, and examines how the directive enables and impacts their utilization. The analysis highlights the challenges and opportunities associated with integrating EVs into the grid, including infrastructure upgrades, regulatory barriers, and market design limitations. Case studies and modeling efforts across EU member states are reviewed to illustrate the current state and potential of EV flexibility implementation. Finally, policy recommendations are proposed to enhance the role of EVs as a crucial flexibility resource in the EU's evolving electricity market, emphasizing the need for targeted regulations, economic incentives, and standardized technical protocols to fully unlock their potential.

description: It is commonly assumed that the observation of an interference pattern is incompatible with any information about the path taken by a quantum particle. Here we show that, contrary to this assumption, the experimentally observable effects of small polarization rotations applied in the slits of a double slit experiment indicate that individual particles passing the slits before their detection in the interference pattern are physically delocalized with regard to their interactions with the local polarization rotations. The rate at which the polarization is flipped to the orthogonal state is a direct measure of the fluctuations of the polarization rotation angles experienced by each particle. Particles detected in the interference maxima experience no fluctuations at all, indicating a presence of exactly one half of the particle in each slit, while particles detected close to the minima experience polarization rotations much larger than the local rotations, indicating a negative presence in one of the slits and a presence of more than one in the other.

description: We consider the nonlinear Schr{ö}dinger equation with a defocusing nonlinearity which is mass-(super)critical and energy-subcritical. We prove uniform in time error estimates for the Lie-Trotter time splitting discretization. This uniformity in time is obtained thanks to a vectorfield which provides time decay estimates for the exact and numerical solutions. This vectorfield is classical in scattering theory, and requires several technical modifications compared to previous error estimates for splitting methods.

description: We report a multiband transport study of bilayer graphene at high carrier densities. Employing a poly(ethylene)oxide-CsClO$_4$ solid polymer electrolyte gate we demonstrate the filling of the high energy subbands in bilayer graphene samples at carrier densities $|n|\geq2.4\times 10^{13}$ cm$^{-2}$. We observe a sudden increase of resistance and the onset of a second family of Shubnikov de Haas (SdH) oscillations as these high energy subbands are populated. From simultaneous Hall and magnetoresistance measurements together with SdH oscillations in the multiband conduction regime, we deduce the carrier densities and mobilities for the higher energy bands separately and find the mobilities to be at least a factor of two higher than those in the low energy bands.

description: Introduction: The apolipoprotein E ɛ4-allele (APOE-ɛ4) increases the risk not only for Alzheimer’s disease (AD) but also for Parkinson’s disease dementia and dementia with Lewy bodies (collectively, Lewy body dementia [LBD]). Hippocampal volume is an important neuroimaging biomarker for AD and LBD, although its association with APOE-ɛ4 is inconsistently reported. We investigated the association of APOE-ε4 with hippocampal atrophy quantified using magnetic resonance imaging in AD and LBD. Areas covered: Databases were searched for volumetric and voxel-based morphometric studies published up until December 31st, 2020. Thirty-nine studies (25 cross-sectional, 14 longitudinal) were included. We observed that (1) APOE-ε4 was associated with greater rate of hippocampal atrophy in longitudinal studies in AD and in those who progressed from mild cognitive impairment to AD, (2) association of APOE-ε4 with hippocampal atrophy in cross-sectional studies was inconsistent, (3) APOE-ɛ4 may influence hippocampal atrophy in dementia with Lewy bodies, although longitudinal investigations are needed. We comprehensively discussed methodological aspects, APOE-based therapeutic approaches, and the association of APOE-ε4 with hippocampal sub-regions and cognitive performance. Expert opinion: The role of APOE-ɛ4 in modulating hippocampal phenotypes may be further clarified through more homogenous, well-powered, and pathology-proven, longitudinal investigations. Understanding the underlying mechanisms will facilitate the development of prevention strategies targeting APOE-ɛ4.

description: Kernel matrices are crucial in many learning tasks such as support vector machines or kernel ridge regression. The kernel matrix is typically dense and large-scale. Depending on the dimension of the feature space even the computation of all of its entries in reasonable time becomes a challenging task. For such dense matrices the cost of a matrix-vector product scales quadratically with the dimensionality N , if no customized methods are applied. We propose the use of an ANOVA kernel, where we construct several kernels based on lower-dimensional feature spaces for which we provide fast algorithms realizing the matrix-vector products. We employ the non-equispaced fast Fourier transform (NFFT), which is of linear complexity for fixed accuracy. Based on a feature grouping approach, we then show how the fast matrix-vector products can be embedded into a learning method choosing kernel ridge regression and the conjugate gradient solver. We illustrate the performance of our approach on several data sets.

description: In this paper matrix orthogonal polynomials in the real line are described in terms of a Riemann--Hilbert problem. This approach provides an easy derivation of discrete equations for the corresponding matrix recursion coefficients. The discrete equation is explicitly derived in the matrix Freud case, associated with matrix quartic potentials. It is shown that, when the initial condition and the measure are simultaneously triangularizable, this matrix discrete equation possesses the singularity confinement property, independently if the solution under consideration is given by recursion coefficients to quartic Freud matrix orthogonal polynomials or not.

But that does not take into account some other facts: 500,000 soldiers missing, 3 million prisoners of war, 1.1 million disabled, 6 million refugees and tens of thousands of civilian victims. The uncertain nature of these calculations, the delayed national mourning and private mourning hampered by distance and false news made these losses unbearable for the population. Finally, the civil war which followed the Great War made the demographic toll and political significance of these losses far heavier.

description: Adversarial training (AT) is considered to be one of the most reliable defenses against adversarial attacks. However, models trained with AT sacrifice standard accuracy and do not generalize well to novel attacks. Recent works show generalization improvement with adversarial samples under novel threat models such as on-manifold threat model or neural perceptual threat model. However, the former requires exact manifold information while the latter requires algorithm relaxation. Motivated by these considerations, we exploit the underlying manifold information with Normalizing Flow, ensuring that exact manifold assumption holds. Moreover, we propose a novel threat model called Joint Space Threat Model (JSTM), which can serve as a special case of the neural perceptual threat model that does not require additional relaxation to craft the corresponding adversarial attacks. Under JSTM, we develop novel adversarial attacks and defenses. The mixup strategy improves the standard accuracy of neural networks but sacrifices robustness when combined with AT. To tackle this issue, we propose the Robust Mixup strategy in which we maximize the adversity of the interpolated images and gain robustness and prevent overfitting. Our experiments show that Interpolated Joint Space Adversarial Training (IJSAT) achieves good performance in standard accuracy, robustness, and generalization in CIFAR-10/100, OM-ImageNet, and CIFAR-10-C datasets. IJSAT is also flexible and can be used as a data augmentation method to improve standard accuracy and combine with many existing AT approaches to improve robustness.

description: The field of dark matter direct detection has seen important contributions in recent years from experiments involving liquid noble gases, specifically liquid argon and liquid xenon. These detection media offer many properties deemed useful in this search, including fast scintillation response, charge readout, 3-D position reconstruction, and nuclear recoil discrimination. Part of the very rapid emergence and dominance of noble liquids is due to the fact that these technologies are easily scalable to nearly arbitrary size and mass. However, the physics impact of recent results has called into question our understanding of the low-energy response of these detection media, in light of apparent contradictions with a possible low-mass WIMP signal observed in the DAMA/LIBRA and CoGeNT experiments. I discuss recent results and examine the details of this inconsistency.

description: Современные интернет порталы тендерных площадок позволяют эффективно взаимодействовать заказчикам и поставщикам строительных услуг с целью достижения наиболее выгодных условий. Тендеры для строительной сферы имеют несколько отличий от регулярных закупок. Цель настоящего исследования состоит в рассмотрении особенностей проведения строительных тендеров, поэтапное проведение тендера а также выявлению проблем связанных при их проведении. Участником закупок может стать как юридическое, так и физическое лицо, которое соответствует требованиям законодательства и заказчика. Большинство тендеров проводятся в соответствии со стандартной схемой. Участие в тендерах можно представить следующим образом: анализ рынка → выбор и получение электронной подписи → регистрация на ЭТП → поиск тендеров → подготовка финансового обеспечения заведение спецсчета (для участников закупок по 44-ФЗ) → подготовка и подача заявки на участие в закупке → участие в тендере → результат. Рассмотренные способы проведения тендеров со стороны заказчика и подрядчика, являются основными и необходимыми для участия и победы в тендере. Благодаря выявленным недостаткам в ходе рассмотрения проблем при участии в тендерах, были выделены наиболее благоприятные пути для заказчика и подрядчика.
description: the Purpose of this study is to consider the features of construction tenders, stage-by-stage tendering and identification of problems associated with their conduct. A legal entity or an individual who meets the requirements of the legislation and the customer can become a participant of the procurement. Most tenders are conducted in accordance with the standard scheme. Participation in tenders can be summarized as follows: market analysis → select and obtain electronic signatures → check-in at the ETP → search tenders → preparing of financial support the institution of the special account (for participants of procurement for 44-FZ) → preparation and submission of applications for participation in the procurement → participation in the tender → result. The considered methods of tenders from the customer and the contractor are the main and necessary for participation and victory in the tender. Due to the identified shortcomings in the course of consideration of problems with participation in tenders, the most favorable ways for the customer and the contractor were identified.

description: Problem: International bodies such as the World Health Organization call on nation-states to more adequately address health determinants (HD) and strengthen primary healthcare through intersectoral action for health (IAH). Despite many leaders expressing the desire to strengthen IAH, in many countries, practitioners and policy-makers struggle to succeed. This study aims to deepen the understanding of how to maximize the impact on health and HD through collaborations between primary care providers (PCP), public health professionals (PHP), and representatives of sectors other than the health sector (ROS). Method: This research includes a supplementary analysis of a mixed-methods case study on Cuban IAH to clarify and compare the roles of the various actors of interest (PCP, PHP, ROS) in managing HD, including the contexts, mechanisms, and outcomes (CMO) in which IAH occurs in Cuba when involving those particular actors. This is followed by a knowledge synthesis of IAH interventions internationally, providing a variety of different contexts, which enables systematic comparison of the various CMO configurations extracted from those interventions, following a method inspired by realist synthesis. Data for the final CMO analysis and demi-regularity are drawn from both the Cuban case study and the other examples of IAH from around the world that involved PCP, PHP, and ROS. Conclusions: IAH involving PHP, PCP, and ROS can lead to significant, positive health outcomes through the management of HD. A key context in which significant improvement in HD and health outcome occurs is when the IAH are carefully planned based on prior evidence and best practices related to partnership building and public health. Key mechanisms of those interventions include: 1) systematic attention to infrastructures, and activities that successfully increase social capital; 2) which in turn supports the negotiation of complementary and synergistic roles between PCP, PHP and ROS, and 3) using cycles of adjustment based on best practices of quality improvement which enable cumulative and reinforcing synergies over time (years and decades), as projects unfold in complex changing policy and practice environments, and as the multiple actors increase their social capital and experience in dealing with health determinants.

description: Numerical studies are presented to assess error estimates for a separable (Hartree) approximation for dynamically evolving composite quantum systems which exhibit distinct scales defined by their mass and frequency ratios. The relevant error estimates were formally described in our previous work [I. Burghardt, R. Carles, C. Fermanian Kammerer, B. Lasorne, C. Lasser, J. Phys. A. 54, 414002 (2021)]. Specifically, we consider a representative two-dimensional tunneling system where a double well and a harmonic coordinate are cubically coupled. The timedependent Hartree approximation is compared with a fully correlated solution, for different parameter regimes. The impact of the coupling and the resulting correlations are quantitatively assessed in terms of a time-dependent reaction probability along the tunneling coordinate. We show that the numerical error is correctly predicted on moderate time scales by a theoretically derived error estimate.

description: This paper presents an experiment of automatically scoring handwritten descriptive answers in the trial tests for the new Japanese university entrance examination, which were made for about 120,000 examinees in 2017 and 2018. There are about 400,000 answers with more than 20 million characters. Although all answers have been scored by human examiners, handwritten characters are not labeled. We present our attempt to adapt deep neural network-based handwriting recognizers trained on a labeled handwriting dataset into this unlabeled answer set. Our proposed method combines different training strategies, ensembles multiple recognizers, and uses a language model built from a large general corpus to avoid overfitting into specific data. In our experiment, the proposed method records character accuracy of over 97% using about 2,000 verified labeled answers that account for less than 0.5% of the dataset. Then, the recognized answers are fed into a pre-trained automatic scoring system based on the BERT model without correcting misrecognized characters and providing rubric annotations. The automatic scoring system achieves from 0.84 to 0.98 of Quadratic Weighted Kappa (QWK). As QWK is over 0.8, it represents an acceptable similarity of scoring between the automatic scoring system and the human examiners. These results are promising for further research on end-to-end automatic scoring of descriptive answers.

description: We investigate the phenomenon of Bose-Einstein condensation on manifolds constructed as a product of a three-dimensional Euclidian space and a general smooth, compact $d$-dimensional manifold possibly with boundary. By using spectral $ζ$-function methods, we are able to explicitly provide thermodynamical quantities like the critical temperature and the specific heat when the gas of bosons is confined, in the three-dimensional manifold, by the experimentally relevant anisotropic harmonic oscillator potential.

description: The extreme event statistics plays a very important role in the theory and practice of time series analysis. The reassembly of classical theoretical results is often undermined by non-stationarity and dependence between increments. Furthermore, the convergence to the limit distributions can be slow, requiring a huge amount of records to obtain significant statistics, and thus limiting its practical applications. Focussing, instead, on the closely related density of "near-extremes" -- the distance between a record and the maximal value -- can render the statistical methods to be more suitable in the practical applications and/or validations of models. We apply this recently proposed method in the empirical validation of an adapted financial market model of the intraday market fluctuations.

description: A finite element method (FEM) for solving the complex valued k(ω) vs. ω dispersion curve of a 3D metamaterial/photonic crystal system is presented. This 3D method is a generalization of a previously reported 2D eigenvalue method. This method is particularly convenient for analyzing periodic systems containing dispersive (e.g., plasmonic) materials, for computing isofrequency surfaces in the k-space, and for calculating the decay length of the evanescent waves. Two specific examples are considered: a photonic crystal comprised of dielectric spheres and a plasmonic fishnet structure. Hybridization and avoided crossings between Mie resonances and propagating modes are numerically demonstrated. Negative index propagation of four electromagnetic modes distinguished by their symmetry is predicted for the plasmonic fishnets. By calculating the isofrequency contours, we also demonstrate that the fishnet structure is a hyperbolic medium.

description: We present an analysis of the stellar kinematics of the Large Magellanic Cloud based on ~5900 new and existing velocities of massive red supergiants, oxygen-rich and carbon-rich AGB stars, and other giants. After correcting the line-of-sight velocities for the LMC's space motion and accounting for asymmetric drift in the AGB population, we derive a rotation curve that is consistent with all of the tracers used, as well as that of published HI data. The amplitude of the rotation curve is v_0=87+/-5 km s^-1 beyond a radius R_0=2.4+/-0.1 kpc, and has a position angle of the kinematic line of nodes of theta=142 degrees +/-5 degrees. By examining the outliers from our fits, we identify a population of 376 stars, or >~5% of our sample, that have line-of-sight velocities that apparently oppose the sense of rotation of the LMC disk. We find that these kinematically distinct stars are either counter-rotating in a plane closely aligned with the LMC disk, or rotating in the same sense as the LMC disk, but in a plane that is inclined by 54 degrees +/- 2 degrees to the LMC. Their kinematics clearly link them to two known HI arms, which have previously been interpreted as being pulled out from the LMC. We measure metallicities from the Ca triplet lines of ~1000 LMC field stars and 30 stars in the kinematically distinct population. For the LMC field, we find a median [Fe/H]=-0.56 +/- 0.02 with dispersion of 0.5 dex, while for the kinematically distinct stars the median [Fe/H] is -1.25 +/- 0.13 with a dispersion of 0.7 dex. The metallicity differences provide strong evidence that the kinematically distinct population originated in the SMC. This interpretation has the consequence that the HI arms kinematically associated with the stars are likely falling into the LMC, instead of being pulled out.

description: We consider the Schrodinger equation with a logarithmic nonlinearity and a repulsive harmonic potential. Depending on the parameters of the equation, the solution may or may not be dispersive. When dispersion occurs, it does with an exponential rate in time. To control this, we change the unknown function through a generalized lens transform. This approach neutralizes the possible boundary effects, and could be used in the case of the Schrodinger equation without potential. We then employ standard splitting methods on the new equation via a nonuniform grid, after the logarithmic nonlinearity has been regularized. We also discuss the case of a power nonlinearity and give some results concerning the error estimates of the first-order Lie-Trotter splitting method for both cases of nonlinearities. Finally extensive numerical experiments are reported to investigate the dynamics of the equations.
