Published: April 2020

Background: Clinical placements are essential for applied learning experiences in health professions education. Unfortunately, there is little consensus on how best to prepare learners for the transition between academic and clinical learning. We explored learners’ perceptions of hospital-based orientation and resulting preparedness for clinical placement.
Methods: Sixty-three learners participated in a total of 18 semi-structured focus groups, during their clinical placements. Data were analyzed thematically.
Results: We organized learners’ perceptions of hospital-based orientation that support their preparedness for placement into three themes: (1) adequate site orientation for learner acquisition of organization acumen and (2) clinical preceptor training to support unit/service and (3) individual components.
Conclusion: Thoughtful attention to hospital-based orientation can support learners in transitioning from academic to clinical learning. Hospital organizations should attend to all three components during orientation to better support learners’ preparedness for clinical learning.

<p><strong>Resumen</strong></p><p>Montefiore Health System, red de hospitales universitarios afiliados al Albert Einstein College of Medicine, ha sido uno de los principales frentes de batalla contra el COVID-19 en la ciudad de Nueva York, epicentro occidental de la pandemia. Con múltiples campuses localizados principalmente en el Bronx, donde la tasa de infección por COVID-19 es de 2,048/100,000 habitantes, ha tenido que enfrentar la pandemia desde sus inicios. La experiencia acumulada a lo largo de estos meses es invaluable, aunque desafortunadamente gran parte de ella ha sido adquirida en base a ensayo y error, dada la novedad de este virus y la ausencia de guías de manejo basadas en la evidencia. Nuestra experiencia es también relevante ya que el 35% de nuestra población es de raza Hispana. En las siguientes páginas repasamos aquello que sabemos sobre los inicios del SARS-CoV-2, las tesis más aceptadas acerca de su fisiopatología, su curso clínico, el manejo inicial una vez el paciente es admitido a nuestra institución con el diagnóstico de COVID-19. También exponemos nuestras experiencias en el manejo terapéutico de las complicaciones multiorgánicas que provoca esta entidad.</p><p> </p><p> </p><p><strong>Abstract</strong></p><p>Montefiore Health System, a network of university hospitals affiliated with the Albert Einstein College of Medicine, has been one of the main fronts in the battle against COVID-19 in New York City, western epicenter of the pandemic. With multiple campuses located mainly in The Bronx, where the rate of infection is of 2,048/100,000 inhabitants, it had to fight the pandemic since its very beginning. The experience gained during these past months is invaluable, although unfortunately most of it had to be learned by trial and error, given the novelty of this coronavirus and the complete lack of evidence-based guidelines. Our experience is particularly relevant given that 35% of our patient population is of Hispanic heritage. In the next few pages, we’ll go over what we currently know about the beginnings of SARS-CoV-2, the currently accepted hypothesis about its pathogenesis, its clinical course, and its initial management once a COVID+ patient is admitted to our institution. We also share our experiences with the clinical management of the multiorgan complications caused by this disease.</p>********
Gravitational Waves from the Phase Transition of NS to QS
Authors: Prasad R , Mallick Ritam 
Published: April 2020

Abstract
In this article, we study the combustion of a neutron star to a hybrid star. We assume that a sudden density fluctuation at the center of the neutron star initiates a shock discontinuity near the center of the star. This shock discontinuity deconfines nuclear matter to two-flavor quark matter, initiating the combustion of the star. This combustion front propagates from the center to the surface, converting nuclear matter to two-flavor quark matter. This combustion stops at some radial point inside the star, as at this density the shock wave becomes rather weak. Although the combustion stops, a simple shock wave propagates to the surface. We study the gravitational-wave signal for such a phase transition of a neutron star to a hybrid star. We find that such a phase transition has a unique gravitational-wave strain of amplitude 10−21. These signals last for few tens of μs and show small oscillating behavior where the phase transition stops. The power spectrum consists of peaks at the fairly high-frequency range. The conversion from neutron star to hybrid star has a unique signature in the gravitational-wave signal, which could help with defining the phase transition and the fate of the neutron star.

Abstract
Enhanced emission from the dense gas tracer HCN (relative to HCO+) has been proposed as a signature of active galactic nuclei (AGN). In a previous single-dish millimeter line survey we identified galaxies with HCN/HCO+ (1–0) intensity ratios consistent with those of many AGN but whose mid-infrared spectral diagnostics are consistent with little to no (≲15%) contribution of an AGN to the bolometric luminosity. To search for putative heavily obscured AGN, we present and analyze NuSTAR hard X-ray (3–79 keV) observations of four such galaxies from the Great Observatories All-sky LIRG Survey. We find no X-ray evidence for AGN in three of the systems and place strong upper limits on the energetic contribution of any heavily obscured (

) AGN to their bolometric luminosity. The upper limits on the X-ray flux are presently an order of magnitude below what XDR-driven chemistry models predict are necessary to drive HCN enhancements. In a fourth system we find a hard X-ray excess consistent with the presence of an AGN, but contributing only ∼3% of the bolometric luminosity. It is also unclear if the AGN is spatially associated with the HCN enhancement. We further explore the relationship between HCN/HCO+ (for several J
upper levels) and

for a larger sample of systems in the literature. We find no evidence for correlations between the line ratios and the AGN fraction derived from X-rays, indicating that HCN/HCO+ intensity ratios are not driven by the energetic dominance of AGN, nor are they reliable indicators of ongoing supermassive black hole accretion.
Magnetic Fields and Afterglows of BdHNe: Inferences from GRB 130427A, GRB 160509A, GRB 160625B, GRB 180728A, and GRB 190114C

Abstract
GRB 190114C is the first binary-driven hypernova (BdHN) fully observed from initial supernova (SN) appearance to the final emergence of the optical SN signal. It offers an unprecedented testing ground for the BdHN theory, which is here determined and further extended to additional gamma-ray bursts (GRBs). BdHNe comprise two subclasses of long GRBs, with progenitors a binary system composed of a carbon–oxygen star (COcore) and a neutron star (NS) companion. The COcore explodes as an SN, leaving at its center a newborn NS (νNS). The SN ejecta hypercritically accretes on both the νNS and the NS companion. BdHNe I are very tight binaries, where the accretion leads the companion NS to gravitationally collapse into a black hole (BH). In BdHN II, the accretion rate onto the NS is lower, so there is no BH formation. We observe the same afterglow structure for GRB 190114C and other selected examples of BdHNe I (GRB 130427A, GRB 160509A, GRB 160625B) and for BdHN II (GRB 180728A). In all cases, the afterglows are explained via the synchrotron emission powered by the νNS, and their magnetic field structures and their spin are determined. For BdHNe I, we discuss the properties of the magnetic field embedding the newborn BH, which was inherited from the collapsed NS and amplified during the gravitational collapse process, and surrounded by the SN ejecta.

Abstract
We present optical observations of the Type Ia supernova (SN) 2019ein, starting two days after the estimated explosion date. The spectra and light curves show that SN 2019ein belongs to a high-velocity (HV) and broad-line group with a relatively rapid decline in the light curves (Δm
15(B) = 1.36 ± 0.02 mag) and a short rise time (15.37 ± 0.55 days). The Si ii
λ6355 velocity, associated with a photospheric component but not with a detached high-velocity feature, reached ∼20,000 km s−1 12 days before the B-band maximum. The line velocity, however, decreased very rapidly and smoothly toward maximum light, to ∼13,000 km s−1, which is relatively low among HV SNe. This indicates that the speed of the spectral evolution of HV SNe Ia is correlated with not only the velocity at maximum light, but also the light-curve decline rate, as is the case for normal-velocity (NV) SNe Ia. Spectral synthesis modeling shows that the outermost layer at >17,000 km s−1 is well described by an O–Ne–C burning layer extending to at least 25,000 km s−1, and there is no unburnt carbon below 30,000 km s−1; these properties are largely consistent with the delayed detonation scenario and are shared with the prototypical HV SN 2002bo despite the large difference in Δm
15(B). This structure is strikingly different from that derived for the well-studied NV SN 2011fe. We suggest that the relation between the mass of 56Ni (or Δm
15) and the extent of the O–Ne–C burning layer provides an important constraint on the explosion mechanism(s) of HV and NV SNe.
2016 Outburst of H 1743–322: XMM-Newton and NuSTAR View
Authors: Chand Swadesh , Agrawal V. K. , Dewangan G. C. , Tripathi Prakash , Thakur Parijat 
Published: April 2020

Abstract
We report the detection of a type C quasi-periodic oscillation (QPO) along with an upper harmonic in the commensurate ratio of 1:2 in two observations of the low-mass black hole transient H 1743–322 jointly observed by XMM-Newton and NuSTAR during the 2016 outburst. We find that the QPO and the upper harmonic exhibit shifts in their centroid frequencies in the second observation with respect to the first one. The hardness intensity diagram implies that in contrast to the 2008 and 2014 failed outbursts, the 2016 outburst was a successful one. We also detect the presence of a broad iron Kα line at ∼6.5 keV and a reflection hump in the energy range 15–30 keV in both of the observations. Along with the shape of the power density spectra, the nature of the characteristic frequencies and the fractional rms amplitude of the timing features imply that the source stayed in the low/hard state during these observations. Moreover, the photon index and other spectral parameters also indicate the low/hard state behavior of the source. Unlike the soft lag detected in this source during the 2008 and 2014 failed outbursts, we observe hard time lags of 0.40 ± 0.15 s and 0.32 ± 0.07 s in the 0.07–0.4 Hz frequency range in the two observations during the 2016 outburst. The correlation between the photon index and the centroid frequency of the QPO is consistent with the previous results. Furthermore, the high value of the Comptonized fraction and the weak thermal component indicate that the QPO is being modulated by the Comptonization process.
A Flexible Method for Estimating Luminosity Functions via Kernel Density Estimation
Authors: Yuan Zunli , Jarvis Matt J. , Wang Jiancheng 
Published: April 2020

AbstractWe propose a flexible method for estimating luminosity functions (LFs) based on kernel density estimation (KDE), the most popular nonparametric density estimation approach developed in modern statistics, to overcome issues surrounding the binning of LFs. One challenge in applying KDE to LFs is how to treat the boundary bias problem, as astronomical surveys usually obtain truncated samples predominantly due to the flux-density limits of surveys. We use two solutions, the transformation KDE method () and the transformation–reflection KDE method () to reduce the boundary bias. We develop a new likelihood cross-validation criterion for selecting optimal bandwidths, based on which the posterior probability distribution of the bandwidth and transformation parameters forandare derived within a Markov Chain Monte Carlo sampling procedure. The simulation result shows thatandperform better than the traditional binning method, especially in the sparse data regime around the flux limit of a survey or at the bright end of the LF. To further improve the performance of our KDE methods, we develop the transformation–reflection adaptive KDE approach (). Monte Carlo simulations suggest that it has good stability and reliability in performance, and is around an order of magnitude more accurate than using the binning method. By applying our adaptive KDE method to a quasar sample, we find that it achieves estimates comparable to the rigorous determination in a previous work, while making far fewer assumptions about the LF. The KDE method we develop has the advantages of both parametric and nonparametric methods.

Quelle différence y a-t-il entre la peinture et la purée ? Quelle est la particularité des matières qu’on appelle « plastiques » ? Que cherche un enfant lorsqu’il les transforme ? Cet article soutient que le petit enfant, à la manière des artistes, a besoin de se sentir créateur . Car il est un chercheur qui essaie de donner forme – une forme singulière – à des questions informulables. Les matières plastiques, en particulier, lui offrent un laboratoire où exercer sa plus grande liberté : chercher pour créer.

Les prospections menées au cours de l’année 2018 sur le site antique de Guellala/Haribus (Jerba) ont permis de mettre au jour une riche documentation archéologique s’étalant entre le v
e s. av. J.-C. et la deuxième moitié du vii
e s. apr. J.-C. De par son emplacement au sud du golfe de Boughrara et étant sur la route maritime qui mène vers la Tripolitaine, ce site était très ouvert sur le commerce méditerranéen comme en témoignent les céramiques importées aussi bien de l’Afrique que d’ailleurs. Ces marchandises arrivaient à Guellala à travers un port qui vient d’être localisé. Sa nécropole romaine mal conservée est aujourd’hui connue à travers deux tombes taillées dans l’argile : une intacte qui a été fouillée en 2014 et une autre complètement pillée.
Del istmo a las murallas reales: Un desafío para la arqueología preislámica de Septem (ss. I-VII d.C.)
Authors: Villada Fernando , Bernal Casasola Darío 
Published: April 2020

Septem Fratres (Ceuta) fue una de tantas ciudades romanas costeras del estrecho de Gibraltar centradas en la explotación de los recursos del mar. Sus vestigios se sitúan en la zona ístmica, un lugar habitado ininterrumpidamente los dos últimos milenios, circunstancia que ha comprometido la conservación de los niveles más antiguos. Desde los años noventa del pasado siglo, la intensificación y sistematización de las intervenciones arqueológicas urbanas no solo ha aportado nueva información cuantitativa y cualitativamente relevante sobre este periodo, sino que además ha puesto de manifiesto que, bajo las fortificaciones abaluartadas del frente occidental, estos niveles preislámicos se conservan en mejor estado, abriéndose de este modo novedosas perspectivas de investigación a corto, medio y largo plazo.

Ce troisième volet de la publication
préliminaire des fouilles des Thermes du Levant, conduites par la Mission
archéologique française en Libye de 1994 à 2012, est dédié au mobilier
en verre et en pierre sélénite. Cette documentation, qui prend en
compte l’essentiel du matériel exhumé, fournit l’occasion rare
d’étudier la verrerie d’époque romaine découverte en Tripolitaine hors
des contextes funéraires.Varié, ce mobilier comprend de la
vaisselle, du luminaire, des objets de jeu et de parure et du vitrage.
Ce dernier met en évidence la coexistence de vitres en verre et en
pierre dans un même édifice. L’étude de la vaisselle du iiie s. révèle des formes rares ou nouvelles
utilisées dans l’édifice balnéaire. Le mobilier de l’Antiquité
tardive, accumulé après l’abandon des bâtiments, permet d’observer la
part des importations égyptiennes et celle des productions de
l’Afrique proconsulaire.
Henchir Tawrirt (Jerba) : un site libyque aux origines
Authors: Ben Tahar Sami 
Published: April 2020

Les recherches archéologiques conduites entre
2006 et 2008 sur Henchir Tawrirt, site situé au sud-est de l’île de
Jerba, ont mis au jour des vestiges s’étalant de la Protohistoire
jusqu’à l’époque romaine. Les plus anciennes traces d’occupation
humaine consistent en des fonds de cabanes qui ont livré, outre des
outils en silex, une poterie complètement inconnue jusqu’alors : il
s’agit de la céramique à empreintes de vannerie. Cette dernière serait
la réplique insulaire d’une poterie protohistorique caractéristique du
Sahara libyen. À l’époque punique, ce site s’est ouvert sur la
Méditerranée, probablement à partir du ve s. av. J.-C. comme en témoignent les
amphores importées de Carthage et de la Grande Grèce, destinées à
contenir du vin. Vers la fin du i
er s.
ou au début du ii
e s. apr. J.-C., un grand
édifice, vraisemblablement une villa rurale, y a été construit,
destiné à exploiter les denrées agricoles qui y étaient produites.

Le site de Port-la-Nautique à Narbonne a livré un ensemble remarquable d’amphores datées entre 30 av. et 70 apr. J.-C. découvertes lors de fouilles subaquatiques. Si les amphores du nord-est de l’Espagne sont majoritaires, quelques amphores africaines témoignent de l’arrivée de ces produits. Malgré leur faible représentativité, les différentes formes découvertes dans le dépotoir portuaire de Port-la-Nautique confirment que ces importations correspondent à plusieurs zones de productions nord-africaines.
