Comparing Short Gamma-Ray Burst Jet Structure Models
Authors: Hayes Fergus , Heng Ik Siong , Veitch John , Williams Daniel 
Published: March 2020

Abstract
A structured gamma-ray burst (GRB) jet could explain the dimness of the prompt emission observed from GRB 170817A, but the exact form of this structure is still ambiguous. However, with the promise of future joint gravitational wave (GW) and GRB observations, we shall be able to examine populations of binary neutron star (BNS) mergers rather than on a case-by-case basis. We present an analysis that considers GW triggered BNS events both with and without short GRB counterparts assuming that events without a counterpart were observed off-axis. This allows for Bayes factors to be calculated to compare different jet structure models. We perform model comparison between a Gaussian and power-law apparent jet structure on simulated data to demonstrate that the correct model can be distinguished with a log Bayes factor of >5 after fewer than 100 events. Constraints on the apparent structure jet model parameters are also made. After 25(100) events the angular width of the core of a power-law jet structure can be constrained within a 90% credible interval of width ∼9.1(4.4)°, and the outer beaming angle to be within ∼19.9(8.5)°. Similarly, we show the width of a Gaussian jet structure to be constrained to ∼2.8(1.6)°.

Abstract
We present multiwavelength studies of a transient X-ray source, XMMSL1 J131952.3+225958, associated with the galaxy NGC 5092 at z = 0.023 detected in the XMM-Newton SLew survey (XMMSL). The source brightened in the

band by a factor of

in 2005 as compared with previous flux limits and then faded by a factor of >200 as observed with XMM-Newton in 2013 and with Swift in 2018. At the flaring state the X-ray spectrum can be modeled with a blackbody at a temperature of ∼60 eV and an overall luminosity of

erg s−1. A UV flare and optical flare were also detected with the Galaxy Evolution Explorer and the Sloan Digital Sky Survey, respectively, within several months of the X-ray flare, whose nonstellar UV–optical spectrum can be described with a blackbody at a temperature of

K and a luminosity of

erg s−1. Interestingly, mid-infrared monitoring observations of NGC 5092 with the Wide-field Infrared Survey Explorer 5–13 yr later show a continuous flux decline. These dramatic variability properties, from the X-ray through UV and optical to infrared, appear to be orderly, suggestive of a stellar tidal disruption event (TDE) by a massive black hole, confirming the postulation by Kanner et al. This TDE candidate belongs to a rare sample with contemporaneous bright emission detected in the X-ray, UV, and optical, which are later echoed by dust-reprocessed light in the mid-infrared. The black hole has a mass of

10

, residing in a galaxy that is dominated by a middle-aged stellar population of 2.5 Gyr.
MOCMC: Method of Characteristics Moment Closure, a Numerical Method for Covariant Radiation Magnetohydrodynamics
Authors: Ryan Benjamin R. , Dolence Joshua C. 
Published: March 2020

Abstract
We present a conservative numerical method for radiation magnetohydrodynamics with frequency-dependent full transport in stationary spacetimes. This method is stable and accurate for both large and small optical depths and radiation pressures. The radiation stress–energy tensor is evolved in flux-conservative form, and closed with a swarm of samples that each transport a multigroup representation of the invariant specific intensity along a null geodesic. In each zone, the enclosed samples are used to efficiently construct a Delaunay triangulation of the unit sphere in the comoving frame, which in turn is used to calculate the Eddington tensor, average source terms, and adaptively refine the sample swarm. Radiation four-forces are evaluated in the moment sector in a semi-implicit fashion. The radiative transfer equation is solved in invariant form deterministically for each sample. Since each sample carries a discrete representation of the full spectrum, the cost of evaluating the transport operator is independent of the number of frequency groups, representing a significant reduction of algorithmic complexity for transport in frequency-dependent problems. The major approximation we make in this work is performing scattering in an angle-averaged way. Local adaptivity in samples also makes this scheme more amenable to nonuniform meshes than a traditional Monte Carlo method. We describe the method and present results on a suite of test problems. We find that Method of Characteristics Moment Closure converges at least as ∼N
−1, rather than the canonical Monte Carlo N
−1/2, where N is the number of samples per zone.

Abstract
We have developed a new coherent dedispersion mode to study the emission of fast radio bursts (FRBs) that trigger the voltage capture capability of the Australian SKA Pathfinder (ASKAP) interferometer. In principle the mode can probe emission timescales down to 3 ns with full polarimetric information preserved. Enabled by the new capability, here we present a spectropolarimetric analysis of FRB 181112 detected by ASKAP, localized to a galaxy at redshift 0.47. At microsecond time resolution the burst is resolved into four narrow pulses with a rise time of just 15 μs for the brightest. The pulses have a diversity of morphology, but do not show evidence for temporal broadening by turbulent plasma along the line of sight, nor is there any evidence for periodicity in their arrival times. The pulses are highly polarized (up to 95%), with the polarization position angle varying both between and within pulses. The pulses have apparent rotation measures that vary by

and apparent dispersion measures that vary by

. Conversion between linear and circular polarization is observed across the brightest pulse. We conclude that the FRB 181112 pulses are most consistent with being a direct manifestation of the emission process or the result of propagation through a relativistic plasma close to the source. This demonstrates that our method, which facilitates high-time-resolution polarimetric observations of FRBs, can be used to study not only burst emission processes, but also a diversity of propagation effects present on the gigaparsec paths they traverse.
A Nonthermal Bomb Explains the Near-infrared Superflare of Sgr A*
Authors: Gutiérrez Eduardo M. , Nemmen Rodrigo , Cafardo Fabio 
Published: March 2020

Abstract
The Galactic center supermassive black hole, Sgr A*, has experienced a strong, unprecedented flare in 2019 May when its near-infrared luminosity reached much brighter levels than ever measured. We argue that an explosive event of particle acceleration to nonthermal energies in the innermost parts of the accretion flow—a nonthermal bomb—explains the near-infrared light curve. We discuss potential mechanisms that could explain this event such as magnetic reconnection and relativistic turbulence acceleration. Multiwavelength monitoring of such superflares in radio, infrared, and X-rays should allow a concrete test of the nonthermal bomb model and put better constraints on the mechanism that triggered the bomb.
Little Brown Bats Utilize Multiple Maternity Roosts Within Foraging Areas: Implications for Identifying Summer Habitat
Authors: Slough Brian G. , Jung Thomas S. 
Published: March 2020

Abstract
Identifying habitat features that may influence the survival and fitness of threatened species is often constrained by a lack of information about the appropriate scale for habitat conservation efforts. Canada's Species at Risk Act lists little brown bats Myotis lucifugus as Endangered and there is a need to determine the scale for delineating important summer habitat features that should be protected. We used a 19-y dataset of banded little brown bats in a 15,000-km2 area of southern Yukon, Canada, to examine fidelity to roost sites and potential foraging areas. We captured and banded 4,349 bats during 208 live-trapping sessions at maternity roosts. Adult females used multiple roosts during the maternity period, separated by up to 6.1 km, within foraging areas, to which individuals exhibited fidelity. Our fidelity rates (≤ 60.5%) are the lowest, and roost-switching rates (≤ 35.5%) the greatest, reported for little brown bats. A small percentage (14.0–20.7%) of females banded as juveniles returned to their natal roosts or foraging areas as adults. We infrequently observed long-distance (25–200 km) switching to novel foraging areas (&lt; 1% of banded bats). We established bat houses to mitigate the loss of a cabin roost; 46.3% of the bats banded at the cabin occupied these houses. The longest documented period of roost fidelity was 18 y, by a female banded as an adult. Roost fidelity by returning adult females declined annually by 3.8–5.3% due to natural mortality, roost switching, or dispersal. Having a choice of multiple maternity roosts within a foraging area may permit little brown bats to select optimal microclimatic conditions throughout the maternity season. Given that fidelity to foraging areas may be higher than to specific roost sites for little brown bats, identification of summer habitat based on foraging areas may be a more effective conservation strategy than relying solely on roost sites.
Apports de la géochimie isotopique de bivalves dulcicoles à la reconstitution paléoenvironnementale en milieu urbain : le cas de la ville de Lyon
Authors: Le Callonnec Laurence , Gaillot Stéphane , Belavoine Juliette , Pons Fabien 
Published: March 2020

L’installation et le développement de la ville de
Lyon depuis l’Antiquité ont été en partie influencés par le
fonctionnement des deux cours d’eau qui encadrent la presqu’île : la
Saône et le Rhône. Des coquilles de lamellibranches et de gastéropodes
dulçaquicoles ont été récoltées dans des niveaux archéologiques afin
d’étudier l’enregistrement isotopique (δ13C et
δ18O) de ces biominéralisations. En effet, la
malacofaune enregistre plus ou moins directement les changements
hydrologiques et climatiques. L’étude s’est focalisée sur deux
périodes climatiques extrêmes : l’Optimum Climatique Médiéval et le
Petit Âge Glaciaire. Une troisième période moins documentée correspond
au Haut-Empire Romain (Antiquité). Les sites étudiés sont localisés
sur la presqu’île : près de la rive gauche de la Saône, à proximité de
l’ancienne zone de confluence et près de la rive droite du Rhône, en
contrebas de la colline de Fourvière à proximité de la rive droite de
la Saône.

Toutes les coquilles ont une signature isotopique
caractéristique de la Saône. Cela semble indiquer une utilisation
privilégiée des alluvions de cette rivière par l’Homme. Des
paléotempératures de l’eau de la Saône ont été estimées entre 17,2 et
18,5 °C. Elles montrent un écart moyen de près de 1,3 °C entre l’OCM
et le PAG. Les coquilles du Haut-Empire enregistrent des températures
intermédiaires (18,1 °C). Au Moyen Âge, autour de l’an mil, le δ13C très négatif des coquilles correspondrait à des
épisodes de tourbification et de paludification des berges dû à une
accalmie du régime hydrologique de la rivière et à un réchauffement
climatique. Cette étude montre l’intérêt de l’enregistrement
géochimique des coquilles de mollusques comme archive climatique à
haute résolution temporelle (année), en domaine continental et
notamment en milieu urbain. Ce milieu peut en effet être marqué par
une variabilité rapide et fréquente et par la disparition de nombreux
autres marqueurs du fait de l’activité humaine.

Authors: Hajnasiri Hamideh , Moafi Farnoosh , Nami Masomeh , Safaralinezhad Atefeh 
Published: March 2020

Introduction:
Sexual function is a part of human life and behavior. It is considered a multidimensional phenomenon that it is influenced by various biological, psychological, and social factors. Pregnancy plays an important role in female sexual function and behavior. This study was conducted to investigate the sexual function and to determine the prevalence of sexual dysfunction among pregnant women during the trimesters of pregnancy.

Methods:
This study is a cross-sectional study conducted in 2016 on 150 pregnant women who referred to the health centers affiliated to Qazvin University of Medical Sciences, in Qazvin. Samples were recruited through convenience sampling. For data collection, a personal and midwifery characteristics checklist, the Female Sexual Function Index, and Depression Anxiety, Stress scales were used. Collected data were then analyzed using SPSS using descriptive statistics, one-way ANOVA, and univariate and multivariate regression models. P < 0.05 was considered statistically significant for all tests.

Results:
Thirty-three percent of pregnant women suffered from sexual dysfunction. The mean and standard deviation of the female sexual function score were 44.7 ± 26.11. Sexual dysfunction among pregnant women during the first, second, and third trimesters were 2%, 20%, and 78%, respectively. Sexual function was correlated with gestational age (P < 0.05); however, the mean sexual function score was lower during the third trimester. There was also a significant relationship between sexual function with the mother's age and education.

Conclusion:
The prevalence of sexual dysfunction during pregnancy was high. Therefore, pregnant women and their spouses need counseling on the physical and mental changes during pregnancy.
Insights into the Electrochemical Corrosion Behavior and Mechanism of Electroless Ni-P Coating in the CO2/H2S/Cl− Environment

Published: March 2020

The electrochemical corrosion behavior of Ni-P coating in 3.5 wt% NaCl solution-containing CO2 and H2S was investigated using electrochemical methods and surface characterization techniques. The results show that the presence of H2S can enhance the CO2 corrosion of Ni-P coated carbon steel by affecting both anodic and cathodic processes. The adsorbed layer only exists in the very early stage of corrosion and barely improves the anticorrosion performance of the coating. The formation of corrosion products (NiO and Ni3S2) renders temporary protection during immersion, but the addition of H2S accelerates the diffusion process at the electrolyte/coating interface and promotes the electrolyte penetration through the coating, causing severe localized corrosion and coating disbondment. A corrosion model is proposed to illustrate the corrosion and degradation process of Ni-P coated steel in the CO2/H2S/Cl− environment.
A predictive group-contribution model for the viscosity of aqueous organic aerosol
Authors: Gervasi Natalie R. , Topping David O. , Zuend Andreas 
Published: March 2020

Abstract. The viscosity of primary and secondary organic aerosol (SOA) has important implications for the processing of aqueous organic aerosol phases in the atmosphere, their involvement in climate forcing, and transboundary pollution. Here we introduce a new thermodynamics-based group-contribution model, which is capable of accurately predicting the dynamic viscosity of a mixture over several orders of magnitude (∼10-3 to >1012 Pa s) as a function of temperature and mixture composition, accounting for the effect of relative humidity on aerosol water content. The mixture viscosity modelling framework builds on the thermodynamic activity coefficient model AIOMFAC (Aerosol Inorganic–Organic Mixtures Functional groups Activity Coefficients) for predictions of liquid mixture non-ideality, including liquid–liquid phase separation, and the calorimetric glass transition temperature model by DeRieux et al. (2018) for pure-component viscosity values of organic components. Comparing this new model with simplified modelling approaches reveals that the group-contribution method is the most accurate in predicting mixture viscosity, although accurate pure-component viscosity predictions (and associated experimental data) are key and one of the main sources of uncertainties in current models, including the model presented here. Nonetheless, we find excellent agreement between the viscosity predictions and measurements for systems in which mixture constituents have a molar mass below 350 g mol−1. As such, we demonstrate the validity of the model in quantifying mixture viscosity for aqueous binary mixtures (glycerol, citric acid, sucrose, and trehalose), aqueous multicomponent mixtures (citric acid plus sucrose and a mixture of nine dicarboxylic acids), and aqueous SOA surrogate mixtures derived from the oxidation of α-pinene, toluene, or isoprene. We also use the model to assess the expected change in SOA particle viscosity during idealized adiabatic air parcel transport from the surface to higher altitudes within the troposphere. This work demonstrates the capability and flexibility of our model in predicting the viscosity for organic mixtures of varying degrees of complexity and its applicability for modelling SOA viscosity over a wide range of temperatures and relative humidities.
