The SUPERWIDE Catalog: A Catalog of 99,203 Wide Binaries Found in Gaia and Supplemented by the SUPERBLINK High Proper Motion Catalog
Authors: Hartman Zachary D. , Lépine Sébastien 
Published: April 2020

Abstract
We present a catalog of 99,203 wide binary systems, initially identified as common proper motion (CPM) pairs from a subset of ∼5.2 million stars with proper motions

, selected from Gaia data release 2 (DR2) and the SUPERBLINK high proper motion catalog. CPM pairs are found by searching for pairs of stars with angular separations <1° and proper motion differences

. A Bayesian analysis is then applied in two steps. In a first pass, we use proper motion differences and angular separations to distinguish between real binaries and chance alignments. In a second pass, we use parallax data from Gaia DR2 to refine our Bayesian probability estimates. We present a table of 119,390 pairs which went through the full analysis, 99,203 of which have probabilities >95% of being real wide binaries. Of those 99,203 high-probability pairs, we estimate that only about 364 pairs are most likely to be false positives. In addition, we identify 57,506 pairs that have probabilities greater than 10% from the first pass but have high parallax errors and therefore were not vetted in the second pass. We examine the projected physical separation distribution of our highest probability pairs and note that the distribution is a simple exponential tail and shows no evidence of being bimodal. Among pairs with lower probability, wide binaries are detected at larger separations (>104–105 au), consistent with the very wide population suggested in previous studies; however, our analysis suggests that these do not represent a distinct population, but instead represent either the exponential tail of the “normal” wide binary distribution or are simply chance alignments of unrelated field stars. We examine the Hertzsprung–Russell diagram of this set of high-probability wide binaries and find evidence for 980 overluminous components among 2227 K + K wide binaries; assuming these represent unresolved subsystems, we determine that the higher-order multiplicity fraction for K + K wide systems is at least 39.6%.

Published: April 2020

<p>This research puts forth an optimization- based analog beamforming scheme for millimeter-wave (mmWave) massive MIMO systems. Main aim is to optimize the combination of analog precoder / combiner matrices for the purpose of getting near-optimal performance. Codebook-based analog beamforming with transmit precoding and receive combining serves the purpose of compensating the severe attenuation of mmWave signals. The existing and traditional beamforming schemes involve a complex search for the best pair of analog precoder / combiner matrices from predefined codebooks. In this research, we have solved this problem by using Particle Swarm Optimization (PSO) to find the best combination of precoder / combiner matrices among all possible pairs with the objective of achieving near-optimal performance with regard to maximum achievable rate. Experiments prove the robustness of the proposed approach in comparison to the benchmarks considered. <strong></strong></p><p class="IndexTerms"> </p>
Comedy of a Common Man: Miller's Comedic Chops
Authors: Abbotson Susan C. W. 
Published: April 2020

Abstract
While critics have acknowledged the often comic moments in Miller's best-known tragedies and in 1968's The Price, which Miller labeled as a comedy, they tend to overlook other dramas that Miller wrote as fully comic, such as The Creation of the World and Other Business (1972), The Ride Down Mt. Morgan (1991), Mr. Peters' Connections (1998), Resurrection Blues (2002), and Finishing the Picture (2004). These are plays that have a lot of connection to one another in terms of style and have found scarce production and lukewarm reception, mostly, I believe, because critics and audiences just do not know how to accept or understand Miller the comedian. This essay opens up that conversation and asks for a reconsideration of Miller's comic intents.

Tick anaphylaxis triggered by pulling out the tick
Authors: Takayama Noriya , Takagaki Yusaku 
Published: April 2020

BackgroundReports of tick anaphylaxis are extremely rare in Asian countries, with poor awareness in these regions. Herein, we report a case of tick anaphylaxis that was triggered by pulling out the tick.Case PresentationA 66‐year‐old man developed pruritus in his left toes after returning from a mountain. Three days later, he found a swollen tick biting at the skin between the second and third toes and pulled it out. Approximately 30 min after pulling out the tick, he started to feel a burning sensation in his chest and was brought to our hospital. He was diagnosed with anaphylactic shock (systolic blood pressure, 60 mmHg) and immediately received intramuscular adrenaline.ConclusionTo our knowledge, this is the first case of tick anaphylaxis triggered by tick removal in an Asian country. A tick should be removed without pressure on its body, especially in patients with tick or bee allergy.
Experimental study of the influence of temperature and cooling method on mechanical properties of granite: Implication for geothermal mining

Published: April 2020

AbstractIn geothermal mining, the mechanical properties and micro‐structure of the rock under different temperature or cooling modes are highly relevant to the stability of the artificial reservoir. For reflect the actual working conditions, an experimental study is carried out on high‐temperature granite that has been cooled both naturally and rapidly with water. The following conclusions are reached. (a) The wave velocity, elastic modulus, and uniaxial compressive strength of the test specimen decrease with an increase in its heating temperature under both cooling modes. (b) The characteristics of the stress‐strain curve of granite are different after different temperatures and cooling modes. With natural cooling, the stress‐strain curve features double peaks in the range of 200‐300°C, whereas such phenomenon occurs at temperatures greater than 300°C with water cooling. (c) When the temperature is less than 300°C, no obvious change occurs in the crystal structure of the sample. When the temperature is more than 300°C, the original micro‐cracks gradually expand and eventually develop into larger cracks.
An ALE method for simulations of axisymmetric elastic surfaces in flow
Authors: Mokbel Marcel , Aland Sebastian 
Published: April 2020

SummaryThe dynamics of membranes, shells, and capsules in fluid flow has become an active research area in computational physics and computational biology. The small thickness of these elastic materials enables their efficient approximation as a hypersurface, which exhibits an elastic response to in‐plane stretching and out‐of‐plane bending, possibly accompanied by a surface tension force. In this work, we present a novel arbitrary Lagrangian‐Eulerian (ALE) method to simulate such elastic surfaces immersed in Navier‐Stokes fluids. The method combines high accuracy with computational efficiency, since the grid is matched to the elastic surface and can, therefore, be resolved with relatively few grid points. The focus of this work is on axisymmetric shapes and flow conditions, which are present in a wide range of biophysical problems. We formulate axisymmetric elastic surface forces and propose a discretization with surface finite‐differences coupled to evolving finite elements. We further develop an implicit coupling strategy to reduce time step restrictions. We show in several numerical test cases that accurate results can be achieved at computational times on the order of minutes on a single core CPU. We demonstrate two state‐of‐the‐art applications which to our knowledge cannot be simulated with any other numerical method so far: we present first simulations of the observed shape oscillations of novel microswimming shells and the uniaxial compression of the cortex of a biological cell during an AFM experiment.
Multimodal water age distributions and the challenge of complex hydrological landscapes
Authors: Rodriguez Nicolas B. , Benettin Paolo , Klaus Julian 
Published: April 2020

AbstractTravel time distributions (TTDs) are concise descriptions of transport processes in catchments based on water ages, and they are particularly efficient as lumped hydrological models to simulate tracers in outflows. Past studies have approximated catchment TTDs with unimodal probability distribution functions (pdf) and have successfully simulated tracers in outflows with those. However, intricate flow paths and contrasting water velocities observed in complex hydrological systems may generate multimodal age distributions. This study explores the occurrence of multimodal age distributions in hydrological systems and investigates the consequences of multimodality for tracer transport. Lumped models based on TTDs of varying complexity (unimodal and multimodal) are used to simulate tracers in the discharge of hydrological systems under well‐known conditions. Specifically, we simulate tracer data from a controlled lysimeter irrigation experiment showing a multimodal response and we provide results from a virtual catchment‐scale experiment testing the ability of a unimodal age distribution to simulate a known and more complex multimodal age system. Models are based on composite StorAge Selection functions, defined as weighted sums of pdfs, which allow a straightforward implementation of uni‐ or multi‐modal age distributions while accounting for unsteady conditions. These two experiments show that simple unimodal models provide satisfactory simulations of a given tracer, but they fail in reproducing processes occurring at different temporal scales. Multimodal distributions, instead, can better capture the detailed dynamics embedded in the observations. We conclude that experimental knowledge of flow paths and the systematic use of data from multiple, independent tracers can be used to validate the assumption of water age unimodality. Multimodal age distributions are more likely to emerge in landscapes where the distributions of flow path lengths and/or water velocities are themselves multimodal. In general, age multimodality may not be particularly pronounced and detectable, unless comparable amounts of water with contrasting ages reach a given outflow.
Recent advances in designing conductive hydrogels for flexible electronics

Published: April 2020

AbstractFlexible electronics have emerged as an exciting research area in recent years, serving as ideal interfaces bridging biological systems and conventional electronic devices. Flexible electronics can not only collect physiological signals for human health monitoring but also enrich our daily life with multifunctional smart materials and devices. Conductive hydrogels (CHs) have become promising candidates for the fabrication of flexible electronics owing to their biocompatibility, adjustable mechanical flexibility, good conductivity, and multiple stimuli‐responsive properties. To achieve on‐demand mechanical properties such as stretchability, compressibility, and elasticity, the rational design of polymer networks via modulating chemical and physical intermolecular interactions is required. Moreover, the type of conductive components (eg, electron‐conductive materials, ions) and the incorporation method also play an important role in the conductivity of CHs. Electron‐CHs usually possess excellent conductivity, while ion‐CHs are generally transparent and can generate ion gradients within the hydrogel matrices. This mini review focuses on the recent advances in the design of CHs, introducing various design strategies for electron‐CHs and ion‐CHs employed in flexible electronics and highlighting their versatile applications such as biosensors, batteries, supercapacitors, nanogenerators, actuators, touch panels, and displays.image
Nonasymptotic bounds for the quadratic risk of the Grenander estimator
Authors: Shashiashvili Malkhaz 
Published: April 2020

AbstractThere is an enormous literature on the so-called Grenander estimator, which is merely the nonparametric maximum likelihood estimator of a nonincreasing probability density on [0, 1] (see, for instance, Grenander (1981)), but unfortunately, there is no nonasymptotic (i.e. for arbitrary finite sample size n) explicit upper bound for the quadratic risk of the Grenander estimator readily applicable in practice by statisticians. In this paper, we establish, for the first time, a simple explicit upper bound 2n−1/2 for the latter quadratic risk. It turns out to be a straightforward consequence of an inequality valid with probability one and bounding from above the integrated squared error of the Grenander estimator by the Kolmogorov–Smirnov statistic.
Preliminary analysis of the X-ray emission from the central regions of the Pictor A

Published: April 2020

AbstractHere we present some preliminary results of our analysis of the combined Chandra observations of the Pictor A radio galaxy. All the available Chandra data for the target, consisting of multiple pointings spanning over 15 years and amounting to the total exposure time of 464 ks, have been included in the analysis. We studied in detail the PSFs of the core region in the individual pointings, as well as the radial profile of the X-ray surface brightness of the source in the combined dataset, in order to discriminate between the radiative output of the unresolved core and the host galaxy. Based on these, we have performed spectral modeling of the active nucleus, constraining its variability.
Fully analytical solutions for Bondi accretion in galaxies with a central Black Hole
Authors: Ciotti Luca , Pellegrini Silvia 
Published: April 2020

AbstractThe fully analytical solution for isothermal Bondi accretion on a black hole (MBH) at the center of JJ two-component Jaffe (1983) galaxy models is presented. In JJ models the stellar and total mass density distributions are described by the Jaffe profile, with different scale-lengths and masses, and to which a central MBH is added; all the relevant stellar dynamical properties can also be derived analytically. In these new accretion solutions the hydrodynamical and stellar dynamical properties are linked by imposing that the gas temperature is proportional to the virial temperature of the stellar component. The formulae that are provided allow to evaluate all flow properties, and are then useful for estimates of the accretion radius and the mass flow rate when modeling accretion on MBHs at the center of galaxies.
Thermal and non-thermal connection in radio mini-halos
Authors: Ignesti A. , Brunetti G. , Gitti M. , Giacintucci S. 
Published: April 2020

AbstractSeveral cool-core clusters are known to host a radio mini-halo, a diffuse, steep-spectrum radio source located in their cores, thus probing the presence of non-thermal components as magnetic field and relativistic particles on scales not directly influenced by the central AGN. The nature of the mechanism that produces a population of radio-emitting relativistic particles on the scale of hundreds of kiloparsecs is still unclear. At the same time, it is still debated if the central AGN may play a role in the formation of mini-halos by providing the seed of the relativistic particles. We aim to investigate these open issues by studying the connection between thermal and non-thermal components of the intra-cluster medium. We performed a point-to-point analysis of the radio and the X-ray surface brightness of a compilation of mini-halos. We find that mini-halos have super-linear scalings between radio and X-rays, with radio brightness declining more steeply than the X-ray brightness. This trend is opposite to that generally observed in giant radio halos, thus marking a possible difference in the physics of the two radio sources. Finally, using the scalings between radio and X-rays and assuming a hadronic origin of mini-halos we derive constraints on the magnetic field in the core of the hosting clusters.
Ornithine Transcarbamylase Deficiency Presenting as Acute Liver Failure in Girls
Authors: Selvanathan Arthavan , Hertzog Ashley , Lemberg Daniel A. , Ellaway Carolyn 
Published: April 2020

ABSTRACTOrnithine transcarbamylase deficiency (OTCD) is the most common of the urea cycle disorders and follows an X‐linked inheritance pattern. The classical form in male infants causes vomiting and lethargy in the neonatal period; if untreated the severe hyperammonaemia can cause acute neurotoxic complications and permanent disability. OTCD may also occur in heterozygote female individuals, though the manifestations are variable. We report 2 cases of female paediatric patients with OTCD, who presented with acute liver failure. Both patients had limited oral intake at the time of presentation, causing an absence of orotic aciduria, which delayed the diagnosis. These cases demonstrate the need to consider urea cycle disorders in children presenting with acute liver failure, and that repeating the urine metabolic screen at the time of an unrestricted diet is warranted if there is a high clinical suspicion.

AbstractBackgroundBy early April 2020, the COVID-19 pandemic had infected nearly one million people and had spread to nearly all countries worldwide. It is essential to understand where and how SARS-CoV-2 is transmitted.MethodsCase reports were extracted from the local Municipal Health Commissions of 320 prefectural cities (municipalities) in China, not including Hubei province, between 4 January and 11 February 2020. We identified all outbreaks involving three or more cases and reviewed the major characteristics of the enclosed spaces in which the outbreaks were reported and associated indoor environmental issues.ResultsThree hundred and eighteen outbreaks with three or more cases were identified, involving 1245 confirmed cases in 120 prefectural cities. We divided the venues in which the outbreaks occurred into six categories: homes, transport, food, entertainment, shopping, and miscellaneous. Among the identified outbreaks, 53·8% involved three cases, 26·4% involved four cases, and only 1·6% involved ten or more cases. Home outbreaks were the dominant category (254 of 318 outbreaks; 79·9%), followed by transport (108; 34·0%; note that many outbreaks involved more than one venue category). Most home outbreaks involved three to five cases. We identified only a single outbreak in an outdoor environment, which involved two cases.ConclusionsAll identified outbreaks of three or more cases occurred in an indoor environment, which confirms that sharing indoor space is a major SARS-CoV-2 infection risk.FundingThe work was supported by the Research Grants Council of Hong (no 17202719, C7025-16G), and National Natural Science Foundation of China (no 41977370).
Conformational entropy and specific affinity of M-cholinolytics and ligands of µ-opioid and D2-dopamine receptors
Authors: Darkhovskii Mikhail B. , Dukhovich Felix S. 
Published: April 2020

AbstractThe computation model for evaluation of conformational entropy changes upon binding ligands to receptors is described. Then, changes of conformational entropy component and of binding free energy are compared. Interest to conformational entropy arises from developing new drugs as it might be changed purposefully. It is shown that conformational entropy may be used for prediction of affinity to a certain receptor. Examples of directed affinity change under the modification of substances’ conformational flexibility are given. The specific role of the conformational entropy in the receptor’s protection from the irreversible inactivation is identified.

AbstractMeasuring the genetic relatedness between different species is one of the major challenges in the field of phylogenetics. Genetic distance calculation based on DNA data is highly using a mechanism to determine inter species relationships. Genetic distance computation can be further bifurcated as alignment-free sequencing and alignment based sequencing. With this research we are presenting alignment free genetic distance calculation technique which is based on locality sensitive hashing(LSH). By this approach we are hashing large DNA sequences into numeric arrays and make comparison more efficient and simplified.
