description: Background: Preformed donor-specific HLA antibodies (DSA) are a well-known risk factor in kidney transplantation. There is still considerable debate, however, about the optimal risk stratification among patients with preformed DSA. Additionally, data on the prognostic value of different crossmatch assays in DSA-positive patients are scarce. Methods: DSA-positive living kidney transplant recipients were selected from a multicenter study examining 4233 consecutive renal transplants. An additional 7 patients from 2 further centers were included. Flow cytometric crossmatches (FXM), Luminex-based crossmatches, and virtual crossmatches based on C1q- and C3d-binding antibodies (C1qXM and C3dXM) were performed retrospectively using pretransplant sera and lymphocytes isolated from fresh samples. These samples were obtained from 44 donor and recipient pairs from 12 centers. Clinical outcome data and the control group without DSA were compiled from the previous study and were supplemented by data on 10-y death-censored graft survival (10yGS). Results: Between 19% (C3dXM) and 46% (FXM) of crossmatches were positive. Crossmatch-positive patients showed high incidences of antibody-mediated rejection (AMR) within 6 mo (up to 60% in B-cell FXM+ patients). The incidence of AMR in crossmatch-negative patients ranged between 5% (FXM−) and 13% (C1qXM−). 10yGS was significantly impaired in patients with positive T-cell FXM and total FXM compared with both patients without DSA and those with DSA with negative FXM. Conclusions: Especially FXM are useful for risk stratification, as the outcome of DSA-positive, FXM-negative patients is similar to that of DSA-negative patients, whereas FXM-positive patients have both more AMR and decreased 10yGS. Because of their lower sensitivity, the significance of Luminex-based crossmatches, C1qXM, and C3dXM would have to be examined in patients with stronger DSA.

description: We report results of a new analysis of a deep 95 mu imaging survey with the photo-polarimeter ISOPHOT on board the Infrared Space Observatory, over a half square degree area within the Lockman Hole. To this end we exploit a newly developed parametric algorithm able to identify and clean spurious signals induced by cosmic-rays impacts and by transient effects and non-linearities in the detectors. These results provide us with the currently deepest -- to our knowledge -- far-IR image of the extragalactic sky. Within the survey area we detect thirty-six sources with S/N>3 (corresponding to a flux of 16 mJy), making up a complete flux-limited sample around 100$ mJy. Reliable sources are detected, with decreasing but well-controlled completeness, down to 20 mJy. The source extraction process and the completeness, the photometric and astrometric accuracies of this catalogue have been tested by us with extensive simulations accounting for all the details of the procedure. We estimate source counts down to a flux of ~30 mJy, at which limit we evaluate that from 10% to 20% of the cosmic IR background has been resolved into sources. The 95mu galaxy counts reveal a steep slope at fluxes lower than 100 mJy (alpha~1.6), in excess of that expected for a non-evolving source population. The shape of these counts agrees with those determined by ISO at 15 and 175 mu, and starts setting strong constraints on the evolution models for the far-IR galaxy populations.

description: We study energy transport in a one-dimensional model of elastically colliding particles with alternate masses $m$ and $M$. In order to prevent total momentum conservation we confine particles with mass $M$ inside a cell of finite size. We provide convincing numerical evidence for the validity of Fourier law of heat conduction in spite of the lack of exponential dynamical instability. Comparison with previous results on similar models shows the relevance of the role played by total momentum conservation.

description: We emphasize that the group-theoretical considerations leading to SO(10) unification of electro-weak and strong matter field components naturally extend to space-time components, providing a truly unified description of all generation degrees of freedoms in terms of a single chiral spin representation of one of the groups SO(13,1), SO(9,5), SO(7,7) or SO(3,11). The realization of these groups as higher dimensional space-time symmetries produces unification of all fundamental fermions is a single space-time spinor.

How dynamics constrains probabilities in general probabilistic theories

Publisher: name: arXiv
Year: 2020
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We introduce a general framework for analysing general probabilistic theories, which emphasises the distinction between the dynamical and probabilistic structures of a system. The dynamical structure is the set of pure states together with the action of the reversible dynamics, whilst the probabilistic structure determines the measurements and the outcome probabilities. For transitive dynamical structures whose dynamical group and stabiliser subgroup form a Gelfand pair we show that all probabilistic structures are rigid (cannot be infinitesimally deformed) and are in one-to-one correspondence with the spherical representations of the dynamical group. We apply our methods to classify all probabilistic structures when the dynamical structure is that of complex Grassmann manifolds acted on by the unitary group. This is a generalisation of quantum theory where the pure states, instead of being represented by one-dimensional subspaces of a complex vector space, are represented by subspaces of a fixed dimension larger than one. We also show that systems with compact two-point homogeneous dynamical structures (i.e. every pair of pure states with a given distance can be reversibly transformed to any other pair of pure states with the same distance), which include systems corresponding to Euclidean Jordan Algebras, all have rigid probabilistic structures.

description: We study N=1 supersymmetric SU(N) gauge theories with an antisymmetric tensor and F flavors using the recent proposal of a-maximization by Intriligator and Wecht. This theory had previously been studied using the method of "deconfinement", but such an analysis was not conclusive since anomalous dimensions in the non-perturbative regime could not be calculated. Using a-maximization we show that for a large range of F the theory is at an interacting superconformal fixed point. However, we also find evidence that for a range of F the theory in the IR splits into a free "magnetic" gauge sector and an interacting superconformal sector.

description: We present OH maser observations at 1612, 1665, 1667, and 1720 MHz for 86 post-asymptotic giant branch (post-AGB) stars selected from a survey of 1612 MHz maser sources in the Galactic Plane. The observations were taken with the Parkes Telescope and the Australia Telescope Compact Array between 2002 September and 2003 August. Post-AGB stars are the precursors to planetary nebulae, the diverse morphological range of which is unexplained. The maser observations were taken to investigate the onset and incidence of wind asymmetries during the post-AGB phase. We re-detected all 86 sources at 1612 MHz while 27 sources were detected at 1665 and 45 at 1667 MHz. One source was re-detected at 1720 MHz. We present a classification scheme for the maser profiles and show that 25% of sources in our sample are likely to have asymmetric or bipolar outflows. From a comparison of the maser and far-infrared properties we find that there is a likely trend in the shape of the maser profiles with some sources evolving from double-peaked to irregular to fully bipolar profiles. A subset of higher-mass sources stand out as having almost no mainline emission and mostly double-peaked profiles. At least 25% of sources in the sample are variable at one or more of the frequencies observed. We also confirm a previously-noted 1667 MHz overshoot phenomenon.

description: We investigate numerically efficient approximations of eigenspaces associated to symmetric and general matrices. The eigenspaces are factored into a fixed number of fundamental components that can be efficiently manipulated (we consider extended orthogonal Givens or scaling and shear transformations). The number of these components controls the trade-off between approximation accuracy and the computational complexity of projecting on the eigenspaces. We write minimization problems for the single fundamental components and provide closed-form solutions. Then we propose algorithms that iterative update all these components until convergence. We show results on random matrices and an application on the approximation of graph Fourier transforms for directed and undirected graphs.

description: We investigate the stabilizability of discrete-time linear switched systems, when the sole control action of the controller is the switching signal, and when the controller has access to the state of the system in real time. Despite their apparent simplicity, determining if such systems are stabilizable appears to be a very challenging problem, and basic examples have been known for long, for which the stabilizability question is open. We provide new results allowing us to bound the so-called stabilizability radius, which characterizes the stabilizability property of discrete-time linear switched systems. These results allow us to compute significantly improved explicit lower bounds on the stabilizability radius for the above-mentioned examples. As a by-product, we exhibit a discontinuity property for this problem, which brings theoretical understanding of its complexity.

description: Sparse polynomial chaos expansions (PCE) are a popular surrogate modelling method that takes advantage of the properties of PCE, the sparsity-of-effects principle, and powerful sparse regression solvers to approximate computer models with many input parameters, relying on only few model evaluations. Within the last decade, a large number of algorithms for the computation of sparse PCE have been published in the applied math and engineering literature. We present an extensive review of the existing methods and develop a framework for classifying the algorithms. Furthermore, we conduct a unique benchmark on a selection of methods to identify which approaches work best in practical applications. Comparing their accuracy on several benchmark models of varying dimensionality and complexity, we find that the choice of sparse regression solver and sampling scheme for the computation of a sparse PCE surrogate can make a significant difference, of up to several orders of magnitude in the resulting mean-squared error. Different methods seem to be superior in different regimes of model dimensionality and experimental design size.

The findings suggest that managers can develop certain strategies to improve customer attitudes and buying intentions.

description: Analyses of key macroeconomic variables of the economies of Nigeria and Zimbabwe suggest that their respective agricultural growth patterns had some impact on their import demand for food and agricultural commodities during the decade of the 1970's. Nigeria's production structure of agriculture dominated by smallholder farming and a relatively even distribution of rural purchasing power, which are characteristic of the Uniformly Small Farm (USF) growth pattern, enhanced aggregate effective domestic demand via linkages and encouraged domestic consumption oriented production. Conversely, Zimbabwe's Dual Size Structure (DSS) pattern of agricultural growth gave rise to a depressed domestic demand structure with weak links to the larger economy, and fostered commercial, export oriented production. The former resulted in strong import demand, the latter in food exports.

description: We revisit the subject of Be star candidates towards the Magellanic Clouds, previously studied by the authors using SPM4 proper motions. We obtain GAIA DR2 parallaxes and proper motions for 2357 and 994 LMC and SMC Be candidates, respectively. Parallaxes and proper motions vs. color V-I easily reveal the presence of the redder galactic contaminant foreground, as concluded in our previous work, but this time we do find a few red Be stars candidates consistent with being true Magellanic objects. A membership assessment to each Magellanic Cloud is done for each Be candidate, based on the distribution of their parallaxes and proper motions. From a compilation of published catalogues of spectroscopically confirmed Be stars, we found that 40 (LMC) and 64 (SMC) of these Be candidates, are in fact Be stars. Near infrared IRSF JHKs magnitudes were obtained for about 70% the Be stars candidates with GAIA DR2 astrometric data. Mid-infrared SAGE IRAC 3.6, 4.5, 5.8 and 8.0 $μ$m magnitudes were obtained for about 85% as well. 6 LMC and 7 SMC confirmed Be stars show optical, near- or mid-infrared colours redder than what has been typically measured for Classical Be stars. Several of the Be candidates follow those redder-than-expected colours distributions suggesting the existence of more red Magellanic Be stars.

description: Recent radial-velocity measurements obtained with the CORALIE spectrograph on the 1.2-m Euler Swiss telescope at La Silla unveil the presence of a new Jovian-mass Hot Jupiter around HD 73256. The 1.85-M_Jup planet moves on an extremely short-period (P=2.5486 d), quasi-circular orbit. The best Keplerian orbital solution is presented together with an unsuccessful photometric planetary-transit search performed with the SAT Danish telescope at La Silla. Over the time span of the observations, the photometric follow-up of the candidate has nevertheless revealed a P=14-d photometric periodicity corresponding to the rotational period of the star. This variation as well as the radial-velocity jitter around the Keplerian solution are shown to be related to the fair activity level known for HD 73256.

description: The complexity and temporal as well as spatial resolution of transcriptome datasets is constantly increasing due to extensive technological developments. Here we present methods for advanced visualization and intuitive exploration of transcriptomics data as necessary prerequisites in order to facilitate the gain of biological knowledge. Color-coding of structural images based on the expression level enables a fast visual data analysis in the background of the examined biological system. The network-based exploration of these visualizations allows for comparative analysis of genes with specific transcript patterns and supports the extraction of functional relationships even from large datasets. In order to illustrate the presented methods, the tool HIVE was applied for visualization and exploration of database-retrieved expression data for master regulators of Arabidopsis thaliana flower and seed development in the context of corresponding tissue-specific regulatory networks.

description: Abstract

This systematic review is the product of 28 top published journals. The search engines adopted in this study were PubMed, Medline, CINHAL, Cochrane Library, Google Scholar, and Research gate. The inclusion criteria were: 1. Papers published between 2019-2023, 2. Top tier journal articles (High quality), 3. Term COVID-19 4. Preparedness of nursing graduates to practice in clinical setting. The key searching words were COVID-19, Nursing Graduates, Preparedness, Clinical Setting. The present paper highlights that Role of nurses during COVID-19 or any other pandemic commences from the initial assessment and triaging, sample collection and diagnostic testing, assessing the severity of patients, following which providing necessary care to patients with mild-to-moderate symptoms, catering to intensive care of critically ill patient, and are also involved in care of the dead bodies. Despite the resource constraint working conditions in Indian hospitals and concerns regarding personal and family safety, nursing professionals have maintained their sense of duty and are dedicated to patient care. Further, personal sacrifice and professional collegiality of nursing fraternity have increased due to increased burden on the health system during the COVID-19 pandemic. This paper shows the research gaps from different studies in the review of the literature. In this present study of systematic review, 28 recent multiple studies based on exploratory, descriptive, survey and phenomenological studies between 2019 to 2023 were systematically reviewed using the keywords search method. The findings are discussed and research gaps are listed accordingly.

description: Forty years after the initial discovery of light-dependent protein phosphorylation at the thylakoid membrane system, we are now beginning to understand the roles of chloroplast phosphorylation networks in their function to decode and mediate information on the metabolic status of the organelle to long-term adaptations in plastid and nuclear gene expression. With the help of genetics and functional genomics tools, chloroplast kinases and several hundred phosphoproteins were identified that now await detailed functional characterization. The regulation and the target protein spectrum of some kinases are understood, but this information is fragmentary with respect to kinase and target protein crosstalk in a changing environment. In this review, we will highlight the most recent advances in the field and discuss approaches that might lead to a comprehensive understanding of plastid signal integration by protein phosphorylation.

One such AdS$_{4}$ vacua features a symmetry enhancement to $\,\textrm{SU}(2) \times \textrm{U}(1)\,$ while preserving $\,\mathcal{N}=2\,$ supersymmetry.

description: We consider the inequality $f \geqslant f\star f$ for real integrable functions on $d$ dimensional Euclidean space where $f\star f$ denotes the convolution of $f$ with itself. We show that all such functions $f$ are non-negative, which is not the case for the same inequality in $L^p$ for any $1 < p \leqslant 2$, for which the convolution is defined. We also show that all integrable solutions $f$ satisfy $\int f(x){\rm d}x \leqslant \tfrac12$. Moreover, if $\int f(x){\rm d}x = \tfrac12$, then $f$ must decay fairly slowly: $\int |x| f(x){\rm d}x = \infty$, and this is sharp since for all $r< 1$, there are solutions with $\int f(x){\rm d}x = \tfrac12$ and $\int |x|^r f(x){\rm d}x 0$, $\int e^{ε|x|}f(x){\rm d}x < \infty$.

description: We present a systematic analysis of point-contact Andreev reflection (PCAR) spectra for ferromagnetic materials, using both modeling and experimental data. We consider the relationship between ballistic and diffusive transport, the effect of different transport regimes on spin polarization measurements, and the importance of unambiguous identification of the type of transport regime. We find that in a realistic parameter range, the analysis of PCAR spectra of purely diffusive character by a ballistic model yield approximately the same (within ~3%) values of the spin polarization and the barrier strength Z larger by ~ 0.5-0.6. We also consider the dependence of polarization values on Z, and have shown by simple modeling that letting the superconducting gap vary as an adjustable parameter can result in a spurious dependence of the spin-polarization Pc on Z. At the same time we analyzed the effects of finite Z on the apparent value of Pc measured by the PCAR technique, using a large number of examples from both our own measurements and from the literature. We conclude that there is a system-dependent variation in Pc (Z), presumably due to spin-flip scattering at the interface. However, the exact type of this dependence is hard to determine with any statistical certainty.

We provide a collection of guidelines to setting up machine learning projects to make them likely useful for science, less frustrating and time-intensive for the scientist and their computers, and more likely to lead to robust insights. We draw examples and experience from astronomy, but the advice is potentially applicable to other areas in science.

description: Fiscal indicators are important to rural development because they identify the nature and severity of local government fiscal stress in nonmetropolitan areas. This report discusses the state of the art of rural fiscal indicators by comparing rural and urban indicator studies. Although they have certain fundamental characteristics in common, rural and urban studies emphasize different types of fiscal difficulties. Substantial data and statistical problems limit rural fiscal indicator research. Nevertheless, rural fiscal studies appear to be catching up to the level of urban fiscal indicator analysis.
Asymptotically flat, parameterized black hole metric preserving Kerr symmetries

description: Recently the Event Horizon Telescope Collaboration, with very-long baseline interferometric observations, resolved structure at the scale of $\sim5$ Schwarzschild radii about the center of M87$^*$, the supermassive black hole resident at the center of Messier 87. This important observation has paved the way for testing what is known as the "no-hair" theorem, stating that isolated black holes are described by the Kerr metric, parameterized only by their mass and spin. Generic, parameterized spacetimes beyond Kerr allow one to arbitrarily test the no-hair theorem for deviations from the Kerr result with no prior theoretical knowledge or motivation. In this paper, we present such a new general, stationary, axisymmetric and asymptotically flat black hole solution with separable geodesic equations (thus preserving symmetries of a Kerr black hole), extending the previous work of Johannsen. In this new metric, five free non-linear functions parameterically deviate from the Kerr result, allowing one to effectively transform to many alternative black hole solutions present in the literature. We then derive analytic expressions for the Keplerian and epicyclic frequencies, the orbital energy and angular momentum, and the location of the innermost stable orbit of circular equatorial particle orbits. We also compute the image of the photon rings in the new spacetime, which correspond to the boundary of the black hole shadow image taken by the Event Horizon Telescope. We finally compare each quantity for the Kerr result against various parameterizations of the metric, finding that, especially for highly rotating black holes, the two solutions disagree significantly. Such a metric parameterization allows one to perform the no-hair tests in a model-independent way, and finally map constraints to specific alternative theories of gravity.

description: The Motor Carrier Act of 1980 contains a number of provisions likely to have an impact on marketing food and agricultural commodities. Easing of entry restrictions and broadening the • scope of operation for existing trucking firms combined with additions to the list of commodities exempt from economic regulation has increased competition for hauling agricultural commodities. Farmer cooperatives have taken limited advantage of • provisions allowing them to enter for-hire truck operations; contract carriers are now permitted to conduct both contract and common carrier operations. Rates now appear to be set in a free market environment and substantial reductions from previous levels have occurred. Certain discounts are now allowed to buyers who pick up grocery products at the seller's warehouse.

description: Ocean freight rates for heavy grains in the first half of 1982 reached their lowest levels since 1978, despite a 3-percent growth in seaborne grain movements in 1981. A worldwide economic recession and an oversupply of dry cargo carrying capacity was responsible for this downturn. Based on current supply of dry bulk cargo carrying tonnage at the beginning of 1982, and on existing orders for new bulk ship tonnage, supply will continue to increase in the short run. In the absence of appreciable growth in the demand for shipping, continuing oversupply will keep grain rates from increasing appreciably in the near term.
Hamiltonian Analyses of New Set of Dual Actions of Bosonic $p$-Branes
Creators: name: Miao, Yan-Gang
Publisher: name: arXiv
Year: 2004
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We make Hamiltonian analyses of the new set of dual bosonic $p$-brane (including string) actions which contain high non-linearity. The difficulties exist in two basic steps of the Hamiltonian procedure, that is, in calculating canonical momenta and in solving velocities in terms of momenta. The former difficulty can be overcome by an ADM reparametrization of induced metrics, while the latter may be circumvented by some modification to the usual Hamiltonian procedure. We also compare our results with that of the other set composed of known dual $p$-brane actions.

description: We estimate the mass of the pentaquark state with QCD sum rules and find that pentaquark states with isospin $I=0, 1, 2$ lie close to each other around $(1.55\pm 0.15)$ GeV. The experimentally observed baryon resonance $Θ^+ (1540)$ with $S=+1$ can be consistently identified as a pentaquark state if its $J^P={1\over 2}^-$. Such a state is expected in QCD. If its parity is positive, this pentaquark state is really exotic. Now the outstanding issue is to determine its quantum numbers experimentally.
Attention-guided Chained Context Aggregation for Semantic Segmentation

description: The way features propagate in Fully Convolutional Networks is of momentous importance to capture multi-scale contexts for obtaining precise segmentation masks. This paper proposes a novel series-parallel hybrid paradigm called the Chained Context Aggregation Module (CAM) to diversify feature propagation. CAM gains features of various spatial scales through chain-connected ladder-style information flows and fuses them in a two-stage process, namely pre-fusion and re-fusion. The serial flow continuously increases receptive fields of output neurons and those in parallel encode different region-based contexts. Each information flow is a shallow encoder-decoder with appropriate down-sampling scales to sufficiently capture contextual information. We further adopt an attention model in CAM to guide feature re-fusion. Based on these developments, we construct the Chained Context Aggregation Network (CANet), which employs an asymmetric decoder to recover precise spatial details of prediction maps. We conduct extensive experiments on six challenging datasets, including Pascal VOC 2012, Pascal Context, Cityscapes, CamVid, SUN-RGBD and GATECH. Results evidence that CANet achieves state-of-the-art performance.

Urobrachya phoenicea quanzae Hartert, 1903b: 56 (Barraca, on the Quanza River).
Now Euplectes axillaris quanzae (Hartert, 1903). See Hartert, 1919: 145; Traylor, 1962: 125–126; Moreau and Greenway, 1962: 70; Craig, 1993b: 143–145; Dean, 2000: 318–319; Dickinson, 2003: 725; Fry and Keith, 2004: 242–244; and Craig, 2010: 150.
HOLOTYPE: AMNH 726822, adult male, collected at Barraca, 09.11S, 13.58E (Dean, 2000: 370), Cuanza (= Quanza) River, Angola, on 28 May 1901, by C. Hubert Pemberton (no. 561). From the Rothschild Collection.
COMMENTS: Hartert had the single specimen when he described quanzae.
Moreau and Greenway (1962: 70), Dean (2000: 318–319) and Dickinson (2003: 725) recognized quanzae as a subspecies of Eu- plectes axillaris, but Traylor (1962: 125) called attention to the larger size of specimens from the Cuanza River and raised the possibility that quanzae should perhaps be considered a full species. Craig (1993b: 144), Fry and Keith (2004: 243) and Craig (2010: 150) synonymized it with E. axillaris bocagei (Sharpe, 1871).

description: According to a 1979 Vegetable Pesticide Survey, approximately 16 million pounds of pesticides (excluding mineral spirits) were used to control weeds, insects, diseases, and nematodes on 12 vegetable crops in five regions which included 18 States. The five regions are Northeast (NY, NJ), Southeast (NC, SC, GA, FL), Midwest (IL, IN, MI, MN, OH, WI), Northwest (ID, OR, WA), and Southwest (AZ, CO, TX). The 12 vegetable crops include cabbage, cantaloups, carrots, celery, cucumbers, green peas, lettuce, onions, snap beans, sweet corn, tomatoes, and watermelons. Approximately 11.5 million acre-treatments were made ranging from a low of 137,500 treatments on 126,300 acres of cucumbers to a high of 3.2 million treatments on 555,900 acres of sweet corn.
Radiative acceleration and transient, radiation-induced electric fields

description: The radiative acceleration of particles and the electrostatic potential fields that arise in low density plasmas hit by radiation produced by a transient, compact source are investigated. We calculate the dynamical evolution and asymptotic energy of the charged particles accelerated by the photons and the radiation-induced electric double layer in the full relativistic, Klein-Nishina regime. For fluxes in excess of $10^{27}$ ${\rm erg} {\rm cm}^{-2} {\rm s}^{-1}$, the radiative force on a diluted plasma ($n\la 10^{11}$ cm$^{-3}$) is so strong that electrons are accelerated rapidly to relativistic speeds while ions lag behind owing to their larger inertia. The ions are later effectively accelerated by the strong radiation-induced double layer electric field up to Lorentz factors $\approx 100$, attainable in the case of negligible Compton drag. The asymptotic energies achieved by both ions and electrons are larger by a factor 2--4 with respect to what one could naively expect assuming that the electron-ion assembly is a rigidly coupled system. The regime we investigate may be relevant within the framework of giant flares from soft gamma-repeaters.
