Abstract
We explore the impact of pulsar electromagnetic dipole and fallback accretion emission on the luminosity of a suite of kilonova models. The pulsar models are varied over pulsar magnetic field strength, pulsar lifetime, ejecta mass, and elemental abundances; the fallback models are varied over fallback accretion rate and ejecta mass. For the abundances, we use Fe and Nd as representatives of the wind and dynamical ejecta, respectively. We simulate radiative transfer in the ejecta in either 1D spherical or 2D cylindrical spatial geometry. For the grid of 1D simulations, the mass fraction of Nd is 0, 10−4, or 10−3, and the rest is Fe. Our models that fit the bolometric luminosity of AT 2017gfo (the kilonova associated with the first neutron star merger discovered in gravitational waves, GW170817) do not simultaneously fit the B, V, and I time evolution. However, we find that the trends of the evolution in B and V magnitudes are better matched by the fallback model relative to the pulsar model, implying the time-dependence of the remnant source influences the color evolution. Further exploration of the parameter space and model deficiencies is needed before we can describe AT 2017gfo with a remnant source.
Fallback Accretion-powered Supernova Light Curves Based on a Neutrino-driven Explosion Simulation of a 40 M⊙ Star

Published: July 2019

Abstract
We present synthetic light curves (LCs) of fallback-powered supernovae based on a neutrino-driven explosion of a 40

zero-metallicity star with significant fallback accretion onto a black hole that was previously simulated by Chan et al. until shock breakout. Here, we investigate the LC properties of the explosion after shock breakout for various fallback models. Without extra power from fallback accretion, the LC is that of an SN IIP with a plateau magnitude of around −14 mag and a plateau duration of 40 days. With extra power for the LC from fallback accretion, however, we find that the transient can be significantly more luminous. The LC shape can be SN 1987A-like or Type IIP-like, depending on the efficiency of the fallback engine. If the accretion disk forms soon after the collapse and more than 1% of the accretion energy is released as the central engine, fallback accretion-powered supernovae become as luminous as superluminous supernovae. We suggest that Type II superluminous supernovae with broad hydrogen features could be related to such hydrogen-rich supernovae powered by fallback accretion. In the future, such superluminous supernovae powered by fallback accretion might be found among the supernovae from the first stars in addition to pair-instability supernovae and pulsational pair-instability supernovae.
Theory of the Formation of Forbush Decrease in a Magnetic Cloud: Dependence of Forbush Decrease Characteristics on Magnetic Cloud Parameters
Authors: Petukhova A. S. , Petukhov I. S. , Petukhov S. I. 
Published: July 2019

Abstract
A theory of the formation of Forbush decrease in a magnetic cloud is presented. It is found that the formation mechanism is the energy loss of cosmic rays in a magnetic cloud represented as a moving magnetic loop with a helical field. The Forbush decrease amplitude, the components of the vector, and tensor anisotropies are calculated along the path of the magnetic cloud passing Earth. It is shown that the Forbush decrease characteristics depend on the following magnetic cloud parameters: magnetic field strength, the helical field structure, velocity and the velocity gradient, and geometric dimensions. It is found that the Forbush decrease characteristics mainly depend on the magnetic field strength and the state of the global helical structure of the field.
A Curated Image Parameter Data Set from the Solar Dynamics Observatory Mission

Published: July 2019

Abstract
We provide a large image parameter data set extracted from the Solar Dynamics Observatory (SDO) mission’s Atmospheric Imaging Assembly (AIA) instrument, for the period of 2011 January through the current date, with the cadence of 6 minutes, for nine wavelength channels. The volume of the data set for each year is just short of 1 TiB. Toward achieving better results in the region classification of active regions and coronal holes, we improve on the performance of a set of 10 image parameters, through an in-depth evaluation of various assumptions that are necessary for calculation of these image parameters. Then, where possible, a method for finding an appropriate setting for the parameter calculations was devised, as well as a validation task to show our improved results. In addition, we include comparisons of JP2 and FITS image formats using supervised classification models, by tuning the parameters specific to the format of the images from which they are extracted and specific to each wavelength. The results of these comparisons show that utilizing JP2 images, which are significantly smaller files, is not detrimental to the region classification task that these parameters were originally intended for. Finally, we compute the tuned parameters on the AIA images and provide a public API (see http://dmlab.cs.gsu.edu/dmlabapi/) to access the data set. This data set can be used in a range of studies on AIA images, such as content-based image retrieval or tracking of solar events, where dimensionality reduction on the images is necessary for feasibility of the tasks.

Abstract
We search Dark Energy Survey (DES) Year 3 imaging for galaxy–galaxy strong gravitational lenses using convolutional neural networks, extending previous work with new training sets and covering a wider range of redshifts and colors. We train two neural networks using images of simulated lenses, then use them to score postage-stamp images of 7.9 million sources from DES chosen to have plausible lens colors based on simulations. We examine 1175 of the highest-scored candidates and identify 152 probable or definite lenses. Examining an additional 20,000 images with lower scores, we identify a further 247 probable or definite candidates. After including 86 candidates discovered in earlier searches using neural networks and 26 candidates discovered through visual inspection of blue-near-red objects in the DES catalog, we present a catalog of 511 lens candidates.
La pile Wonder ne s’use que si l’on s’en sert
Authors: Métayer Michel 
Published: July 2019

Si la pile Wonder ne s’use que si l’on s’en sert, comme l’affirme la réclame, qu’advient-il d’une œuvre d’art lorsqu’elle est lue, représentée, traduite ? Faut-il la maintenir dans un écrin ? À cette question Walter Benjamin répond que toute œuvre qui en mérite le nom possède au contraire une vie-continuée, que celle-ci peut connaître des formes diverses : au cours du temps, l’usure densifie l’œuvre. Formuler quelle est cette densification en rapport avec le temps où nous la connaissons, telle est la tâche du critique.

Si l’UE et l’Afrique divergent sur de nombreux points, elles ont des défis communs à relever. Tourner le dos à un passé pour le moins complexe est une nécessité : construire ensemble un projet prospère, pacifique et durable est une exigence. Le nouveau partenariat UE-Afrique peut-il y parvenir ? Nous privilégions les perspectives économiques, démographiques et migratoires.
Brexit Linkage in Trade Negotiation: A Strategy for Rejecting the European Union – East African Community Economic Partnership Agreement?
Authors: Mwilima Harrison Kalunga 
Published: July 2019

Le vote du Brexit signifiait que le Royaume-Uni pourrait sortir du marché unique européen et mener sa propre politique commerciale. La question est devenue très préoccupante pour certains pays africains qui étaient en train de négocier un accord commercial réciproque avec l’UE. Dans le cas de la Communauté de l’Afrique de l’Est (CAE), certains États partenaires ont refusé de signer un accord de partenariat économique (APE) régional UE-CAE en invoquant le problème de l’incertitude due au Brexit. Afin d’aborder la situation, la question posée ici est la suivante : en quoi le lien entre Brexit et les négociations commerciales accroit-il la possibilité de ne pas conclure un accord APE régional avec la CAE? L’article utilise la stratégie de négociation par liens thématiques pour montrer comment le Brexit a fourni à certains pays une nouvelle occasion d’inclure des clauses de négociation supplémentaires, aboutissant ainsi aux refus de signer l’accord commercial de l’UE.
Consultations avancées de médecins hospitaliers en centres de santé : impacts et difficultés identifiées
Authors: Le Cossec Chloé , de Chambine Sophie , Tugaye Amélie 
Published: July 2019

Objectif : Des consultations avancées avaient été identifiées lors d’un état des lieux des coopérations ville-hôpital réalisé en 2016 à l’Assistance publique – Hôpitaux de Paris. L’étude réalisée vise à apprécier leurs avantages et inconvénients. Méthodes : Des entretiens ont été menés avec les praticiens réalisant les consultations, les chefs de service, les directions (hôpitaux et centres de santé). Un recueil quantitatif a été réalisé pour sept consultations. Résultats : Ces consultations proposaient des soins en secteur 1 dans des zones défavorisées, le recours à une structure de taille plus humaine que l’hôpital et des délais de rendez-vous parfois plus courts. Pour les praticiens, elles permettaient une diversification de l’activité et une découverte de la médecine de ville. Pour le service hospitalier, elles engendraient le recrutement éventuel de patients et un déport du suivi vers le centre de santé pour les patients vivant à proximité. Il ressort que ces consultations permettent de renforcer des liens ville-hôpital déjà existants et informels. Parmi les difficultés, on note l’absence d’interopérabilité des systèmes d’information, la difficulté à mobiliser certains professionnels et une augmentation de la charge de travail. Conclusion : La mise en place de consultations avancées, si elle peut constituer une première étape dans l’organisation des liens entre la ville et l’hôpital, ne permet pas à elle seule d’assurer un maillage territorial. Les partenariats doivent s’élargir à plusieurs centres mais aussi à d’autres structures de ville. Par ailleurs, des partenariats plus larges permettent de formaliser des parcours de soins.

Published: July 2019

Introduction : Au niveau international, une réflexion approfondie sur le rôle des agents de santé communautaire est en cours. L’objectif du travail est d’élaborer un modèle d’intégration des agents de santé communautaire dans le système national de santé. Méthode : L’étude s’est déroulée au Bénin et au Togo. Il s’agissait d’une enquête en grappe qui a concerné les agents de santé communautaire (ASC) au nombre de 385, 238 chefs de villages, 92 responsables de structures de santé sélectionnés par choix raisonné et 6 150 ménages choisis de façon probabiliste. L’analyse des forces, faiblesses, opportunités et menaces des interventions sous directive communautaire a contribué à l’élaboration du modèle. Résultats : Les documents de référence en santé communautaire existaient dans les deux pays. La quasi-totalité (98,4 %) des ASC avait déclaré, avoir reçu une formation avant le début de leur travail. Tous ont une motivation forte pour le travail qu’ils accomplissent. Quant aux chefs de ménage, seuls 31,3 % ont révélé participer à la sélection des ASC de leur localité. L’inexistence de lois reconnaissant le travail des ASC constitue une menace pour leur intégration dans le système de santé. Les principaux éléments proposés dans le modèle sont : l’élaboration du statut des ASC, la rémunération des ASC sur un budget géré par le district sanitaire et alimenté par plusieurs sources. Conclusion : Les ASC ne doivent pas être une alternative délivrant des soins de santé mais une entité à part entière du système national de santé.
Colombie : Processus de paix, subversion du genre et résistances
Authors: González Olga L 
Published: July 2019

Fin 2016, après quatre ans de pourparlers dans des circonstances difficiles, la guérilla de filiation marxiste Forces Armées Révolutionnaires de Colombie, FARC, et le gouvernement colombien sont parvenus à un accord de paix. Un des aspects méconnus de cet accord de paix est la place prise par les « questions LGBT ». Celles-ci sont devenues centrales dans le débat, notamment lors du référendum qui devait approuver cet accord de paix en octobre 2016 et qui a été rejeté par la majorité des votants. Dans ce papier, nous montrons que la question du « genre » est devenue une variable structurelle dans la vie de ce pays. Nous affirmons que pour comprendre la crispation autour de cette question, il est nécessaire de prendre en compte l’histoire et l’évolution des églises et des partis catholiques et évangéliques, ainsi que la place qu’ont aujourd’hui les organisations de défense des droits des personnes LGBT. Le papier montre comment le travail des organisations féministes a ouvert le chemin, à La Havane (lieu des pourparlers), aux organisations travaillant pour les droits LGBT. Il analyse comment la dimension du « genre » a été intégrée au sein de l’académie et des ONG pour aborder les conséquences du conflit. Il retrace les questions qui se posent lorsque la « plus vieille guérilla du monde » doit compter parmi ses alliés politiques avec des secteurs qui mettent en avant le « genre » et la « diversité sexuelle », alors qu’elle-même est en cause pour des agissements sexistes ou homophobes. Enfin, le papier discute les défis posés par le « genre » et montre pourquoi la diversité sexuelle sera une question décisive dans le débat politique et sociétal en Colombie.

Abstract
Background: Early and accurate detection of Listeria in foods is vital. Current methods require 24 h enrichment for detection. Objective: This study aimed to demonstrate enhanced early detection of Listeria in mixed leafy greens using Sample6 DETECT™ HT/L, a phage-based detection system. Methods: A method comparison between the reference method (U.S. Food and Drug Administration Bacteriological Analytical Manual Chapter 10) for the detection of Listeria spp. and the Sample6 DETECT HT/L using a new proprietary R2 Medium was performed in mixed leafy greens. Results: Using the R2 Medium enrichment with Sample6 DETECT HT/L, detection of L. innocua was possible at 12 h (with a centrifugation step), and L. monocytogenes was detected by 18 h, with equivalent performance as the 24 h enrichments using the reference method detection. The Sample6 DETECT HT/L gave an equivalent performance for L. innocua at 15 h as the reference method at 24 h. Detection was accomplished by the addition of reagents in the kit, following the package insert, and reading results in a detection chamber using a 96-well plate reader that detects a fluorescent signal. Conclusions: Results indicate the new R2 Medium and Sample6 DETECT HT/L allowed for earlier detection of Listeria spp. in mixed leafy greens. Highlights: Sample6 DETECT HT/L with the new R2 Medium allowed the early detection of Listeria spp. and may be applied in other food matrices and environmental samples.

Objective(s)
Serious mental illnesses, such as bipolar disorders and schizophrenia, are closely associated with involuntary admission. Many studies have focused on involuntary admission in people with schizophrenia, but little is known about the factors associated with involuntary admission in Chinese patients with bipolar disorders. This study aimed to investigate socio-demographic and clinical factors associated with involuntary admission in Chinese patients with bipolar disorders.

Methods
In this multi-center cross-sectional survey in China, a total of 155 newly admitted patients with bipolar disorders were consecutively recruited from 16 psychiatric institutions from 15 March to 14 April, 2013. Patients’ socio-demographic and clinical data were collected from their medical records. The Modified Overt Aggression Scale and the Insight and Treatment Attitudes Questionnaire were used to measure patients’ level of aggression and insight of current psychiatric illness.

Results
The prevalence of involuntary admission was 52% in this sample of Chinese inpatients with bipolar disorders. In multiple logistic regression, a high level of aggression (odds ratio (OR) = 2.48), diagnosis of manic episode (OR = 3.65), poor insight (OR = 7.52), and a low level of education (OR = 3.13) were significantly associated with involuntary admission.

Conclusion
Manic episode, aggressive behavior, and poor insight were the significant contributing factors to involuntary admission in Chinese patients with bipolar disorders.
Topological characteristics of iterated line graphs in QSAR problem: Octane numbers of saturated hydrocarbons
Authors: Zakharov Anton B. , Dyachenko Anastasia V. , Ivanov Vladimir V. 
Published: July 2019

AbstractCapabilities of line (edge) graph in quantitative structure‐activity relationship (QSAR) problem for constructing predictive models are demonstrated. The basic idea for proposed approach is to describe molecular structure using generated graph sequence: vertex and chain of line graphs. Every following graph in the sequence corresponds to the structure where vertices appear to be edges of the previous one. For every graph, it is proposed to compute corresponding topological and informational descriptors. Employing latter for derivation of predictive equations allows to realize progressive hierarchy of models. As a test problem, the forecast of research octane numbers for saturated hydrocarbons is chosen. Among the descriptors selected to be used for building regression models well‐known Randic connectivity index (χ(1)), first Zagreb index (ZM1) and theoretic‐informational index of vertex complexity (Vc) are employed. Derived hierarchy of regression equations shows systematic improvement in the description of desired property as every new graph is included in consideration. Determination coefficients for training sample and computed via leave‐one‐out cross‐validation procedure reveal that four‐parametric equation with Vc descriptor has satisfactory forecasting facilities. Efficiency of proposed approach was also demonstrated on the example of artificial neural networks.
