description: For spacetimes that are not asymptotic to anti-de Sitter Space (non AAdS), we adapt the Lewkowycz-Maldacena procedure to find the holographic entanglement entropy. The key observation, which to our knowledge is not very well appreciated, is that asymptotic boundary conditions play an essential role on extending the replica trick to the bulk. For non AAdS, we expect the following three main modifications: (1) the expansion near the special surface has to be compatible with the asymptotic expansion; (2) periodic conditions are imposed to coordinates on the phase space with diagonalized symplectic structure, not to all fields appearing in the action; (3) evaluating the entanglement functional using the boundary term method amounts to evaluating the presymplectic structure at the special surface, where some additional exact form may contribute. An explicit calculation is carried out for three-dimensional warped anti-de Sitter spacetime (WAdS3) in a consistent truncation of string theory, the so-called S-dual dipole theory. It turns out that the generalized gravitational entropy in WAdS3 is captured by the least action of a charged particle in WAdS3 space, or equivalently, by the geodesic length in an auxiliary AdS3. Consequently, the bulk calculation agrees with the CFT results, providing another piece of evidence for the WAdS3/CFT2 correspondence.

description: The connection between certain entangled states and graphs has been heavily studied in the context of measurement-based quantum computation as a tool for understanding entanglement. Here we show that this correspondence can be harnessed in the reverse direction to yield a graph data structure which allows for more efficient manipulation and comparison of graphs than any possible classical structure. We introduce efficient algorithms for many transformation and comparison operations on graphs represented as graph states, and prove that no classical data structure can have similar performance for the full set of operations studied.

description: The problem of personalization in Information Retrieval has been under study for a long time. A well-known issue related to this task is the lack of publicly available datasets that can support a comparative evaluation of personalized search systems. To contribute in this respect, this paper introduces SE-PEF (StackExchange - Personalized Expert Finding), a resource useful for designing and evaluating personalized models related to the task of Expert Finding (EF). The contributed dataset includes more than 250k queries and 565k answers from 3 306 experts, which are annotated with a rich set of features modeling the social interactions among the users of a popular cQA platform. The results of the preliminary experiments conducted show the appropriateness of SE-PEF to evaluate and to train effective EF models.

description: The binary (simple metal) phase diagram Au-Cd contains a number of intermetallic compounds with various distortions, superlattices and vacancies. To understand the reasons of these structural complexities and their phase stability, we analyze these crystal structures within the nearly free-electron model in the frame of Fermi sphere - Brillouin zone interactions. Examination of the Brillouin-Jones configuration in relation to the nearly-free electron Fermi sphere provides insights for significance of the valence electron energy contribution to the phase stability. Representation of these complex structures in the reciprocal space clarifies their relationship to simple basic cells. This approach shows the importance of the additional planes for the stability of superslattices. The AuCd-hP18, AuCd3-hP24 and AuCd4-hP273 structures are shown to be related to the AuCd-cP2 via rhombohedral distortion with superlattices and vacancies.

description: Cross modal face matching between the thermal and visible spectrum is a much desired capability for night-time surveillance and security applications. Due to a very large modality gap, thermal-to-visible face recognition is one of the most challenging face matching problem. In this paper, we present an approach to bridge this modality gap by a significant margin. Our approach captures the highly non-linear relationship between the two modalities by using a deep neural network. Our model attempts to learn a non-linear mapping from visible to thermal spectrum while preserving the identity information. We show substantive performance improvement on three difficult thermal-visible face datasets. The presented approach improves the state-of-the-art by more than 10\% on UND-X1 dataset and by more than 15-30\% on NVESD dataset in terms of Rank-1 identification. Our method bridges the drop in performance due to the modality gap by more than 40\%.

description: We compute the effect of a d-wave magnetization (altermagnetism) on the spectrum of bound states (Andreev levels) in a junction between two s-wave superconductors (gap $Δ_0$, phase difference $ϕ$). Compared to a nonmagnetic junction, the $ϕ$-dependence of the spectrum is shifted by an offset $\pmδϕ$, dependent on the spin direction, so that the Andreev levels become spin-polarized. In a planar junction, oriented along the crystalline axis of $d_{xy}$-wave symmetry, the excitation energies are determined by the normal-state transmission probability $T$ according to $E=Δ_0\sqrt{1-T\sin^2\tfrac{1}{2}(ϕ\pmδϕ)}$. We calculate the corresponding Josephson energy and supercurrent, recovering the 0-$π$ transition of related studies.

description: Background: Compelling data on clinical emergency medicine is required for healthcare system management. The aim of this survey was to describe the nationwide status quo of emergency care in Germany at the healthcare system level using the Utstein reporting template as the guideline to measure the data collected. Methods: This cross-sectional survey collected standardized data from German EDs in 2018. All 759 of the EDs listed in a previously collected ED Directory were contacted in November 2019 using the online-survey tool SoSci Survey. Exclusively descriptive statistical analyses were performed. Absolute as well as relative frequencies, medians, means, ranges, standard deviations (SD) and interquartile ranges (IQR) were reported depending on distribution. Main Results: A total of 150 questionnaires of contacted EDs were evaluated (response rate: 19.8%). Hospitals had a median of 403 inpatient beds (n=147). The EDs recorded a median of 30,000 patient contacts (n=136). Eightythree EDs (55%) had observation units with a median of six beds. The special patient groups were pediatric patients (< 5 years) and older patients (> 75 years) with a median of 1.7% and 25%, respectively. Outpatients accounted for 55%, while 45% were admitted (intensive care unit 5.0%, standard care unit 32.3%, observation unit 6.3%) and 1.2% transferred to another hospital. Conclusions: The use of the Utstein reporting template enabled the collection of ED descriptive parameters in Germany. The data can provide a baseline for upcoming reforms on German emergency medicine, and for international comparisons on admission rates, initial triage categories, and patient populations.

description: Accurate segmentation is essential for echocardiography-based assessment of cardiovascular diseases (CVDs). However, the variability among sonographers and the inherent challenges of ultrasound images hinder precise segmentation. By leveraging the joint representation of image and text modalities, Vision-Language Segmentation Models (VLSMs) can incorporate rich contextual information, potentially aiding in accurate and explainable segmentation. However, the lack of readily available data in echocardiography hampers the training of VLSMs. In this study, we explore using synthetic datasets from Semantic Diffusion Models (SDMs) to enhance VLSMs for echocardiography segmentation. We evaluate results for two popular VLSMs (CLIPSeg and CRIS) using seven different kinds of language prompts derived from several attributes, automatically extracted from echocardiography images, segmentation masks, and their metadata. Our results show improved metrics and faster convergence when pretraining VLSMs on SDM-generated synthetic images before finetuning on real images. The code, configs, and prompts are available at https://github.com/naamiinepal/synthetic-boost.

description: Wood et al suggested that mass-loss rate is a function of X-ray flux ($\dot{M} \propto F_x^{1.34}$) for dwarf stars with $F_x \lesssim F_{x,6} \equiv 10^6$ erg cm$^{-2}$ s$^{-1}$. However, more active stars do not obey this relation. These authors suggested that the break at $F_{x,6}$ could be caused by significant changes in magnetic field topology that would inhibit stellar wind generation. Here, we investigate this hypothesis by analysing the stars in Wood et al's sample that had their surface magnetic fields reconstructed through Zeeman-Doppler Imaging (ZDI). Although the solar-like outliers in the $\dot{M}$ -- $F_x$ relation have higher fractional toroidal magnetic energy, we do not find evidence of a sharp transition in magnetic topology at $F_{x,6}$. To confirm this, further wind measurements and ZDI observations at both sides of the break are required. As active stars can jump between states with highly toroidal to highly poloidal fields, we expect significant scatter in magnetic field topology to exist for stars with $F_x \gtrsim F_{x,6}$. This strengthens the importance of multi-epoch ZDI observations. Finally, we show that there is a correlation between $F_x$ and magnetic energy, which implies that $\dot{M}$ -- magnetic energy relation has the same qualitative behaviour as the original $\dot{M}$ -- $F_x$ relation. No break is seen in any of the $F_x$ -- magnetic energy

description: T lymphocytes and myeloid cells express the immunoglobulin-like glycoprotein cluster of differentiation (CD)101, notably in the gut. Here, we investigated the cell-specific functions of CD101 during dextran sulfate sodium (DSS)-induced colitis and Salmonella enterica Typhimurium infection. Similar to conventional CD101 mice, animals with a regulatory T cell-specific Cd101 deletion developed more severe intestinal pathology than littermate controls in both models. While the accumulation of T helper 1 cytokines in a CD101-deficient environment entertained DSS-induced colitis, it impeded the replication of Salmonella as revealed by studying CD101 x interferon-g mice. Moreover, CD101-expressing neutrophils were capable to restrain Salmonella infection in vitro and in vivo. Both cell-intrinsic and -extrinsic mechanisms of CD101 contributed to the control of bacterial growth and spreading. The CD101-dependent containment of Salmonella infection required the expression of Irg-1 and Nox2 and the production of itaconate and reactive oxygen species. The level of intestinal microbial antigens in the sera of inflammatory bowel disease patients correlated inversely with the expression of CD101 on myeloid cells, which is in line with the suppression of CD101 seen in mice following DSS application or Salmonella infection. Thus, depending on the experimental or clinical setting, CD101 helps to limit inflammatory insults or bacterial infections due to cell type-specific modulation of metabolic, immune-regulatory, and anti-microbial pathways.
The Effects of Literacy on Diabetes Control

Year: 2002

description: Introduction: Diabetes Mellitus is a significant public health problem in the United States that results in significant morbidity, mortality, and health care costs. While it is known that tight glucose control is crucial to prevent complications of diabetes, previous studies have shown that inadequate functional health literacy among diabetic patients is associated with low knowledge about diabetes self-management which may hinder patients' ability to adequately control their blood sugars. Many previous studies have examined the association between low literacy and poor diabetes knowledge, but few have examined the association between low literacy and diabetes control as measured by biological measures such as hemoglobin A1c. Methods: Two hundred patients at the Durham VA were surveyed with a demographic questionnaire and tested for literacy using the Rapid Estimate of Adult Literacy in Medicine. Most recent hemoglobin A1c from computerized records was used to assess glycemic control. Results: Persons who were older, had less education, or were non-white had lower levels of literacy. Older persons and those who did not have help at home had lower hemoglobin A1c's than those who were younger or had help at home. When adjusted for age, race, level of education, employment status, financial status, having help at home, and living alone, there was no association between literacy and hemoglobin A1c. Discussion: The results of this study support the theory that increased literacy may be associated with increased knowledge diabetes self-management, but increased literacy may not be directly associated with better glycemic control. Further studies can explore the potential effects of social support and locus of control in diabetes control.

description: For a set A of Boolean functions, a closure operator c and an involution i, let Nc,i (A) be the number of sets which can be obtained from A by repeated applications of c and i . The orbit O(c, i ) is defined as the set of all these numbers. We determine the orbits O(S, i ) where S is the closure defined by superposition and i is the complement or the duality. For the negation non, the orbit O(S, non) is almost determined. Especially, we show that the orbit in all these cases contains at most seven numbers. Moreover, we present some closure operators where the orbit with respect to duality and negation is arbitrarily large.

description: An enhanced ionization injection scheme using a tightly focused laser pulse with intensity near the ionization potential to trigger the injection process in a mismatched pre-plasma channel has been proposed and examined via multi-dimensional particle-in-cell simulations. The core idea of the proposed scheme is to lower the energy spread of trapped beams by shortening the injection distance. We have established theory to precisely predict the injection distance, as well as the ionization degree of injection atoms/ions, electron yield and ionized charge. We have found relation between injection distance and laser and plasma parameters, giving a strategy to control injection distance hence optimizing beam's energy spread. In the presented simulation example, we have investigated the whole injection and acceleration in detail and found some unique features of the injection scheme, like multi-bunch injection, unique longitudinal phase-space distribution, etc. Ultimate electron beam has a relative energy spread (rms) down to 1.4% with its peak energy 190 MeV and charge 1.7 pC. The changing trend of beam energy spread indicates that longer acceleration may further lower the energy spread down to less than 1%, which may have potential in applications related to future coherent light source driven by laser-plasma accelerators.

description: We perform computer simulations to explore the escape dynamics of a self-propelled (active) nanorod from circular confinements with narrow opening(s). Our results clearly demonstrate how the persistent and directed motion of the nanorod helps it to escape. Such escape events are absent if the nanorod is passive. To quantify the escape dynamics, we compute the radial probability density function (RPDF) and mean first escape time (MFET) and show how the activity is responsible for the bimodality of RPDF, which is clearly absent if the nanorod is passive. The broadening of displacement distributions with activity has also been observed. The computed mean first escape time decreases with activity. In contrast, the fluctuations of the first escape times vary in a non-monotonic way. This results high values of the coefficient of variation and indicates the presence of multiple timescales in first escape time distributions and multimodality in uniformity index distributions. We hope our study will help in differentiating activity-driven escape dynamics from purely thermal passive diffusion in confinement.

description: We introduce Doppler time-of-flight (D-ToF) rendering, an extension of ToF rendering for dynamic scenes, with applications in simulating D-ToF cameras. D-ToF cameras use high-frequency modulation of illumination and exposure, and measure the Doppler frequency shift to compute the radial velocity of dynamic objects. The time-varying scene geometry and high-frequency modulation functions used in such cameras make it challenging to accurately and efficiently simulate their measurements with existing ToF rendering algorithms. We overcome these challenges in a twofold manner: To achieve accuracy, we derive path integral expressions for D-ToF measurements under global illumination and form unbiased Monte Carlo estimates of these integrals. To achieve efficiency, we develop a tailored time-path sampling technique that combines antithetic time sampling with correlated path sampling. We show experimentally that our sampling technique achieves up to two orders of magnitude lower variance compared to naive time-path sampling. We provide an open-source simulator that serves as a digital twin for D-ToF imaging systems, allowing imaging researchers, for the first time, to investigate the impact of modulation functions, material properties, and global illumination on D-ToF imaging performance.

description: We study the effect of thermal fluctuations in the XY-model on a surface with non vanishing mean curvature and zero Gaussian curvature. Unlike Gaussian curvature that typically frustrates orientational order, the extrinsic curvature of the surface can act as a local field that promotes long range order at low temperature. We find numerically that the transition from the high temperature isotropic phase to the true long range ordered phase is characterized by critical exponents consistent with those of the flat space Ising model in two dimensions, up to finite size effects. Our results suggest a versatile strategy to achieve geometric control of liquid crystal order by suitable design of the underlying curvature of a substrate or bounding surface.

description: Antimicrobial resistance: what is the public health sector doing to address this increasing threat to the health of the entire world? This is a global threat, not one that impacts just the poor or underdeveloped nations. There appears to be more public recognition of the impact on the public health community, but the question is; has it been validated? Will funding be made available? What progress has been made for prevention and surveillance? Are we all talk and no action? The Centers for Disease Control and Prevention (CDC) has defined the top ten greatest achievements of public heath over the past century. In that list is control of communicable diseases, which includes the discovery, introduction and utilization of antimicrobial agents (Centers for Disease Control and Prevention (CDC), 2011). It is currently accepted that the most significant impact on the increase of human life expectancy can be attributed to Public Health practice and its achievements. Despite this, funding for public health practice and preventative measures is meager at best. Currently, fewer than two percent of health care dollars are utilized for Public Health Protection programs and measures. In the early 1900s the principle causes of death were primarily infectious diseases. As we developed preventative measures, medical treatments and experienced decreased incidence, these causes plummeted down the list. Life expectancy increased substantially. However, we are again faced with the threat of increasing impact of infectious diseases on morbidity and human mortality. More microbes are evolving and developing resistance to the defenses that we have built against them. An overview of current public health initiatives as well as the analysis of antimicrobial stewardship programs and their role in prevention and integration into public health leadership will be reviewed and surmised in this report. In addition recommendations for further action will be discussed based on best practices determined in the current literature review.

description: Circuit topology employs fundamental units of entanglement, known as soft contacts, for constructing knots from the bottom up, utilising circuit topology relations, namely parallel, series, cross, and concerted relations. In this article, we further develop this approach to facilitate the analysis of chirality, which is a significant quantity in polymer chemistry. To achieve this, we translate the circuit topology approach to knot engineering into a braid-theoretic framework. This enables us to calculate the Jones polynomial for all possible binary combinations of contacts in cross or concerted relations and to show that, for series and parallel relations, the polynomial factorises. Our results demonstrate that the Jones polynomial provides a powerful tool for analysing the chirality of molecular knots constructed using circuit topology. The framework presented here can be used to design and engineer a wide range of entangled chain with desired chiral properties, with potential applications in fields such as materials science and nanotechnology.

description: In terms of Bogoliubov-de Gennes approach, we investigate Majorana bound state (MBS) in vortex of proximity-induced superconductivity on the surface of topological insulator. Mapping out the local density of states (LDOS) of quasiparticle excitations as a function of energy and distance from vortex center, it is found that the spectral distribution evolves from "V"-shape to "Y"-shape with emergence of MBS upon variation of chemical potential, consistent with the STM/STS measurement in a very recent experiment [Xu et al., Phys. Rev. Lett. 114, 017001 (2015)] on Bi2Te3 thin layer on the top of NbSe2. Moreover, we demonstrate that there is a "checkerboard" pattern in the relative LDOS between spin up and down channels, which maps out directly the quantum mechanical wave function of MBS. Therefore, spin-resolved STM/STS technique is expected to be able to provide phase sensitive evidence for MBS in vortex core of topological superconductor.

description: Quantifying animal interactions is crucial for understanding various ecological processes, including social community structures, predator-prey dynamics, spreading of pathogens and information. Despite the ubiquity of interaction processes among animals and the advancements in tracking technologies enabling simultaneous monitoring of multiple individuals, a common theoretical framework to analyse movement data is still lacking. The diverse mechanisms governing how organisms perceive the proximity of others have led to species-specific theoretical approaches, hindering a common currency with which to evaluate and compare findings across taxa. We propose a general framework, borrowing tools from statistical physics, specifically from the theory of reaction diffusion processes. While some of these tools have been employed to predict pathogen transmission events, they have not yet pervaded the movement ecology literature. Using both continuous and discrete variables, we demonstrate the suitability of our framework to study interaction processes. Defining interactions as the transfer of information between individuals, we show that the probability of information transfer for the first time is equivalent to the first-passage probability of reacting in a multi-target environment. As interaction events reduce to encounter events for perfectly efficient information transfer, we compare our formalism to a recent approach that takes the joint occupation probability of two animals over a region of interaction as a measure of the encounter probability, rather than the first-encounter probability. We show the discrepancy between the two approaches by comparing analytically their predictions with continuous variables, while with discrete variables we quantify their difference over time. We conclude by pointing to some of the open problems that reaction diffusion formalism might be able to tackle.

Higher Post-transplant Costs and Resource Utilization in Adult Living Donor Liver Transplant Recipients Compared to Deceased Donor Liver Transplant Recipients

description: Living donor liver transplantation (LDLT) is an alternative to traditional deceased donor liver transplantation (DDLT) that has grown out of the shortage of deceased donor livers available for transplantation. The two procedures have similar clinical outcomes, but costs have been shown to be higher in living donor liver transplantation (LDLT) than in deceased donor liver transplantation (DDLT). The aim of this study was to compare the medical resource utilization, costs, and complication rates between LDLT and DDLT. Data were collected on the first 24 LDLT recipients performed at the University of North Carolina at Chapel Hill School of Medicine and were compared to 24 DDLT recipients matched on age, etiology of liver disease, year of transplant, and model for end stage liver disease (MELD) score at the time of transplantation. The study time period was the first 30 days after transplantation. Compared to DDLT recipients, LDLT recipients had significantly longer lengths of stay, 23.2 vs. 15.9 days, p<0.001, as well as number of laboratory tests 2,403 vs. 1,509, p=0.001 and radiology tests, 29.9 vs. 14.7, p<0.001. Costs for ICU care were higher in the LDLT recipients compared to DDLT recipients, $15,504 vs. $7,243, p=0.006. Total costs for LDLT recipients was higher at $61,488 vs. $34,973 for DDLT recipients, p=0.001. The increase in total costs in the LDLT group was largely driven by complications, with a re-transplantation rate of 25%. Resource utilization and costs are higher in LDLT recipients than in DDLT recipients, and may be due the higher complication and re-transplantation rates seen in LDLT. These data may be useful to institutions planning to initiate a LDLT program.

Transverse-field $XY$ spin chain with the competing long-range interactions: Multi-criticality around the $XX$-symmetric point
Creators: name: Nishiyama, Yoshihiro

description: The transverse-field $XY$ spin chain with competing antiferromagnetic long-range interactions, $J_r \propto 1/r^α$ ($r$: distance between spins), and the exponent $α$ was investigated numerically. The main concern is to clarify the character of the transverse-field-driven phase transition for the small-$α$ regime around the $XX$-symmetric point, $η=0$ ($η$: $XY$-anisotropy parameter). To cope with the negative-sign problem, we employed the exact-diagonalization method, which enables us to evaluate the fidelity susceptibility $χ_F$. Because the fidelity susceptibility does not assume any order parameter after a phase transition, it detects the multi-criticality around the $XX$-symmetric point in a systematic manner. As a preliminary survey, with $η=0.5$ and $α=2$ fixed, we made the scaling analysis of $χ_F$. The scaling behavior of $χ_F$ shows that the transverse-field-driven phase transition belongs to the 2D-Ising universality class. Thereby, with the properly crossover-scaled $η$, the $χ_F$ data is cast into the crossover scaling formula for the small-$α$ regime. The multi-critical exponents fed into the scaling formula are argued through referring to related studies.
