Pseudo-redshifts of Gamma-Ray Bursts Derived from the L–T–E Correlation
Authors: Deng 邓 Chen 晨 , Huang 黄 Yong-Feng 永锋 , Xu 许 Fan 帆 
Published: February 2023

Abstract
The X-ray afterglow of many gamma-ray bursts (GRBs) exhibits a plateau phase before the normal power-law decay stage, which may be related to continued activities of the central engine. Tang et al. collected 174 such GRBs and confirmed the so-called L–T–E correlation which involves three key parameters, i.e., the isotropic γ-ray energy E

γ,iso of the prompt phase, the end time T
a of the plateau phase, and the corresponding X-ray luminosity L
X. In this study, the L–T–E correlation is confirmed and updated as

with a large sample consisting of 210 plateau GRBs with known redshifts. The tight correlation is then applied to derive the pseudo-redshift of other 130 plateau GRBs whose redshifts are not directly measured. Statistical analysis is also carried out on this pseudo-redshift sample.

Abstract
This is the first of a series of papers that will introduce a user-friendly, detailed, and modular Galactic Chemical Evolution Model, GalCEM, that tracks isotope masses as a function of time in a given galaxy. The list of tracked isotopes automatically adapts to the complete set provided by the input yields. The present iteration of GalCEM tracks 86 elements broken down into 451 isotopes. The prescription includes massive stars, low-to-intermediate-mass stars, and Type Ia supernovae as enrichment channels. We have developed a preprocessing tool that extracts multidimensional interpolation curves from the input yield tables. These interpolation curves improve the computation speeds of the full convolution integrals, which are computed for each isotope and for each enrichment channel. We map the integrand quantities onto consistent array grids in order to perform the numerical integration at each time step. The differential equation is solved with a fourth-order Runge–Kutta method. We constrain our analysis to the evolution of all light and intermediate elements from carbon to zinc, and lithium. Our results are consistent up to the extremely metal-poor regime with Galactic abundances. We provide tools to track the mass rate change of individual isotopes on a typical spiral galaxy with a final baryonic mass of 5 × 1010
M
⊙. Future iterations of the work will extend to the full periodic table by including the enrichment from neutron-capture channels as well as spatially dependent treatments of galaxy properties. GalCEM is publicly available at https://github.com/egjergo/GalCEM.
Malgré le déploiement du droit des discriminations, les taux de recours demeurent faibles : les enjeux de la mobilisation de l’action en justice
Authors: Latraverse Sophie 
Published: February 2023

En France, le droit des discriminations prend son envol par le droit de l’Union européenne, la transposition des directives n os 2000/43, 2000/78, 2006/54 et la création de la Haute Autorité de lutte contre les discriminations (HALDE). En effet, les pouvoirs de la HALDE ont été conçus pour surmonter les blocages auxquels faisait face l’action en justice. En 2015, la place acquise par ce droit dans le paysage juridique est consacrée par l’organisation conjointe d’un colloque sur dix ans de droit de la non-discrimination par la Cour de cassation, le Conseil d’État, le Défenseur des droits et le Conseil national des barreaux. Mais aujourd’hui la mobilisation en soutien aux victimes pour l’accès aux recours reste un point noir, extrêmement difficile à surmonter. C’est dans ce contexte qu’a été créé le Réseau pour agir en justice contre les discriminations pour organiser le soutien au recours par un travail en réseau sur toute la France.
Entre défiance et haine : discourir sur la danse dans l’espace germanique ( XVI e - XVIII e siècle)
Authors: Mourey Marie-Thérèse 
Published: February 2023

L’article se penche sur les discours sur la danse ayant marqué l’espace germanique durant un « long » xviie siècle. Au-delà d’une hostilité de principe envers la danse et les spectacles, des exemples choisis permettent de mettre en lumière les conceptions divergentes du corps humain, ainsi que les postulats identitaires face aux modèles étrangers. Ils illustrent aussi la singularité de la situation confessionnelle allemande, et les vives résistances à la sécularisation croissante du monde moderne.
Du côté des partisans de la danse : place de l’apologie, portraits de l’adversaire dans les textes du XVII e siècle
Authors: Pfister Béatrice 
Published: February 2023

Cet article se propose d’étudier l’image de la haine pour la danse que la production textuelle favorable à l’art chorégraphique au xviie siècle dessine en creux. Un travail quantitatif permet d’abord de souligner la place remarquablement restreinte du registre polémique et de l’apologie méthodique de la danse dans ce corpus, la plupart des auteurs dédaignant la controverse pour concentrer leurs efforts sur le perfectionnement de la danse. Puis, l’étude des portraits à charge des ennemis de la danse que brossent les textes apologétiques les plus fervents met au jour des thématiques récurrentes qui révèlent un même désir de présenter la haine pour la danse comme marginale et accidentelle.
A-t-on encore besoin de diplomates ?

Comme en 2010, le projet de réforme des retraites annoncé pour l’année 2023 prévoit un report de l’âge d’ouverture des droits et un allongement de la durée de cotisation. Il s’agirait de travailler plus pour « sauver nos pensions ». Dans quelle mesure le système de retraite actuel est-il réellement en danger ? Entre-t-on dans un nouvel âge de la réforme des retraites, visant la réduction de leur durée et du niveau moyen des pensions ?
Contrer l’islamisme
Authors: Bouzar Dounia , Sinaceur Marwan 
Published: February 2023

Les extrémismes qui se réclament de l’islam représentent un défi pour la société française. Les contrer suppose d’en distinguer les diverses composantes : islamisme des Frères musulmans, salafisme non violent et salafisme violent (ou djihadisme). La pratique des auteurs montre que, pour les désamorcer, il est nécessaire de tenir compte de leurs logiques respectives afin de mettre en place des démarches adaptées, au risque d’être, au contraire, contre-productifs.
Quel choix de système de gestion intégré en PME ? Étude multi-cas des combinaisons de critères de sélection
Authors: Deltour François , Mourrain André 
Published: February 2023

La problématique de l’intégration des systèmes d’information est maintenant bien connue, même dans le cas spécifique des PME. L’article avance la connaissance des mécanismes d’adoption des systèmes de gestion intégrés (SGI) en se focalisant sur le moment de la sélection finale, qui peut se caractériser par l’arbitrage suivant : choisir un ERP ou bien choisir un système alternatif ? Cet arbitrage, auquel les PME font face, revient à choisir entre deux types de systèmes dont les capacités d’intégration diffèrent. Afin de comprendre les ressorts de ce choix, la recherche mobilise la méthode d’analyse qualitative comparée (QCA) appliquée à seize cas de PME. Suivant un principe d’équifinalité, cette méthode permet de mettre en évidence différentes combinaisons de critères guidant la sélection par la PME d’un ERP ou bien d’un système alternatif. Les configurations multi-critères identifiées soulignent le rôle central de la complexité comparée des systèmes, en tant que condition nécessaire, mais non suffisante au choix du SGI. Les autres critères (adéquation, compatibilité, coût et engagement de l’intégrateur), selon la manière dont ils sont combinés, vont également influencer le choix au moment de la sélection finale. Ces différentes configurations permettent de discuter les ambitions du projet souhaité par les PME, selon la capacité d’intégration retenue et l’objectif transformationnel visé au moment de la sélection. La recherche offre alors un éclairage renouvelé sur les mécanismes de choix en amont du projet, ces mécanismes ayant des répercussions directes sur la suite du projet dans sa phase d’implémentation.
Time fractional analysis of Casson fluid with application of novel hybrid fractional derivative operator
Authors: Rehman Aziz Ur , Riaz Muhammad Bilal , Khan Ilyas , Mohamed Abdullah 
Published: February 2023

<abstract><p>A new approach is used to investigate the analytical solutions of the mathematical fractional Casson fluid model that is described by the Constant Proportional Caputo fractional operator having non-local and singular kernel near an infinitely vertical plate. The phenomenon has been expressed in terms of partial differential equations, and the governing equations were then transformed in non-dimensional form. For the sake of generalized memory effects, a new mathematical fractional model is formulated based on the newly introduced Constant Proportional Caputo fractional derivative operator. This fractional model has been solved analytically, and exact solutions for dimensionless velocity, concentration and energy equations are calculated in terms of Mittag-Leffler functions by employing the Laplace transformation method. For the physical significance of various system parameters such as $ \alpha $, $ \beta $, $ Pr $, $ Gr $, $ Gm $, $ Sc $ on velocity, temperature and concentration profiles, different graphs are demonstrated by Mathcad software. The Constant Proportional Caputo fractional parameter exhibited a retardation effect on momentum and energy profile, but it is visualized that for small values of Casson fluid parameter, the velocity profile is higher. Furthermore, to validated the acquired solutions, some limiting models such as the ordinary Newtonian model are recovered from the fractionalized model. Moreover, the graphical representations of the analytical solutions illustrated the main results of the	present work. Also, from the literature, it is observed that to deriving analytical results from fractional fluid models developed by the various fractional operators is difficult, and this article contributes to answering the open problem of obtaining analytical solutions for the fractionalized fluid models.</p></abstract>
La protestation AUCHAN DÉGAGE à Dakar
Authors: Ndiaye Abdourahmane 
Published: February 2023

Dans cet article, nous proposons d’explorer les mobilisations alimentaires, à l’instar d’Auchan dégage, une campagne de protestation contre l’offensive de la grande distribution française au Sénégal, sous le prisme de l’approche du conflit, perspective de la sociologie des marchés. La grille d’étude du programme de recherche des mouvements sociaux est retenue comme analyseur des conflits autour des modes de consommation alimentaire. Ce travail s’appuie sur une enquête qualitative effectuée auprès des acteurs de la campagne de protestation. Elle est exploitée selon la méthode de l’analyse de contenu. La perspective retenue postule une consommation qui déborde du périmètre étroit que lui confère habituellement la théorie économique orthodoxe, son étude sous le seul angle de l’acte d’achat. Offrant ainsi la possibilité d’interroger à la fois les rapports de pouvoir, les résistances et les ripostes qui s’organisent au travers des marchés. Aux mobilisations contre la faim des décennies 1970 et 1980 en Afrique se sont substituées d’autres formes de mobilisations autour des enjeux de souveraineté alimentaire et de patriotisme économique, notamment celles organisées depuis 2018 contre la mainmise de la grande distribution française sur les marchés de consommation urbaine au Sénégal. Ce faisant, la mobilisation impulse à la fois un enjeu refondateur à la question du consommer local et une tentative de réappropriation du secteur par un capitalisme périphérique.
L’art de se nourrir en temps de crise aggravée et en contexte d’insécurité alimentaire structurelle
Authors: Raimond Christine , Fougou Hadiza Kiari , Caremel Jean-François , Garine Eric 
Published: February 2023

Dans la région de Diffa au Niger, à une situation alimentaire structurellement déficitaire en raison d’une croissance démographique forte en zone aride, se surimpose une crise sécuritaire liée au groupe djihadiste Boko Haram, qui a entrainé un déplacement massif de population et une crise humanitaire majeure à l’échelle régionale. Au travers d’études successives depuis 2017, complétées par une enquête auprès de personnes hôtes, déplacées et réfugiées, nous analysons les recompositions à l’œuvre dans l’alimentation locale et la commensalité. Malgré l’éclatement des familles, leur redistribution dans le territoire et les ruptures brutales des mobilités qui assuraient les systèmes de subsistances, nous montrons que les habitants persistent à faire encore trois repas par jour, à rassembler la famille, à organiser les repas de fêtes et même à adopter des innovations alimentaires urbaines. Les changements dans l’alimentation ne sont pas tous liés à la crise sécuritaire, ils révèlent aussi l’adoption de pratiques et de produits nouveaux, « faute de mieux » ou par goût de la nouveauté, qui témoignent de dynamiques sur un temps plus long et d’échanges sur de longues distances.

Abstract
Notch ligands present during interactions between T cells and dendritic cells (DCs) dictate cell phenotype through a myriad of effects including the induction of T cell regulation, survival, and cytokine response. The presence of Notch ligands on DCs varies with the context of the inflammatory response; Jagged-1 is constitutively expressed, whereas Delta-like 1 and Delta-like 4 are induced in response to pathogen exposure. Although Delta-like and Jagged ligands send different signals through the same Notch receptor, the role of these two ligands in peripheral T cell immunity is not clear. The goal of our studies was to determine the role of Jagged-1 in the pathogen-free inflammation induced by OVA during allergic airway disease in mice. Our studies show that a deletion in DC-expressed Jagged-1 causes a significant increase in cytokine production, resulting in increased mucus production and increased eosinophilia in the lungs of mice sensitized and challenged with OVA. We also observed that a reduction of Jagged-1 expression is correlated with increased expression of the Notch 1 receptor on the surface of CD4+ T cells in both the lung and lymph node. Through transfer studies using OT-II transgenic T cells, we demonstrate that Jagged-1 represses the expansion of CD44+CD62L+CCR7+ memory cells and promotes the expansion of CD44+CD62L− effector cells, but it has no effect on the expansion of naive cells during allergic airway disease. These data suggest that Jagged-1 may have different roles in Ag-specific T cell responses, depending on the maturity of the stimulated T cell.

Published: February 2023

Background:
Prophylaxis could be an established strategy to potentially prevent and control infectious diseases and should be considered in the coronavirus disease 2019 (COVID-19) pandemic. The present study aimed to assess the effectiveness of hydroxychloroquine as a prophylaxis treatment strategy in the reduction of the risk of COVID-19 among health professionals.

Materials and Methods:
The health professionals were randomly assigned (1:1) to the control group without receiving any hydroxychloroquine as prophylaxis and the hydroxychloroquine group receiving a weekly hydroxychloroquine dose of 400 mg up to 12 weeks.

Results:
A total of 146 health professionals were randomly enrolled in this study between August 11 and November 11 in 2020. Among the screened health professionals, 21 (14.6%) were infected with COVID-19 during the 12 weeks, and 14 (66.6%) out of the 21 health professionals were in the control group. Most participants with COVID-19 had mild symptoms (62%). In addition, 9.5% (n = 2) of the participants suffered from moderate disease and 28.5% were diagnosed with severe symptoms. In the hydroxychloroquine group, 5 (7.1%) and 2 (2.8%) participants were reported with mild and moderate symptoms of COVID-19, respectively, and 2 participants had moderate, 8 (10.9%) participants had mild symptoms, and 6 (8.2%) participants had severe symptoms in the control group, within 3 months. Severe symptoms of COVID-19 were not observed in the hydroxychloroquine group.

Conclusion:
This study addressed the effect and benefit of hydroxychloroquine administration for the prevention of COVID-19 among health professionals. The improved perception of prophylaxis might highlight its important role in future COVID-19 outbreaks to prevent hospital transmission, which is a major route of spread.

Authors: Azizkhani Reza , Azimi Meibody Azita , Sadeghi Ahmad , Meibody-Tabar Gloria , Flechon-Meibody Fleuria , Ataei Behrooz , Kouhestani Soheila 
Published: February 2023

Background:
The present study was to compare the professional quality of life (ProQOL) and its association with the emotional well-being among the physicians and nurses in contact with COVID-19 patients in Iran and France.

Materials and Methods:
The study was performed on 903 nurses and physicians in contact with COVID-19 patients in Iran and France.he subjects completed their demographics online and then answered questions addressing their job stress and emotion associated with their contact with COVID-19 patients and ProQOL. Finally, the collected data were analyzed using the SPSS software (ver. 25).

Results:
According to the results of the present study, the degree of contact with COVID-19 patients had a significant role in compassion satisfaction, burnout, and compassion fatigue, with the coefficient effects of 0.459, 0.688, and 0.433, respectively (P < 0.05). The emotional well-being had a significant role in increasing compassion satisfaction (B = 0.505, P < 0.05).

Conclusion:
According to the results of the present study, factors such as contact with a COVID-19 patient, emotional well-being, gender, and marital status had a significant effect on dimensions of ProQOL in both Iran and France. Considering that the entire focus of the physicians and nurses is on the health of COVID-19 patients and they have no concentration on improving their emotional state, it seems that supporting them in terms of psychological self-care and considering its indirect impact on the quality of professional performance are of particular significance.

Published: February 2023

Background:
Preeclampsia, a pregnancy-specific complication, has been associated with cytomegalovirus (CMV) infection in observational studies. CMV-specific T cell response plays a major role in viremia clearance. We explored whether CMV-specific cell-mediated immunity (CMI) status is associated with preeclampsia in pregnant women.

Materials and Methods:
CMV-specific CMI was assessed using CMV-QuantiFERON (QF-CMV) assay in plasma serum of 35 women with preeclampsia as well as 35 normal pregnant controls, retrospectively. Participants were matched for gestational age in a 1:1 ratio. The proportion of reactive results, the mean value of interferon-gamma (IFN-γ) level produced in mitogen and antigen tubes were compared between the cases and controls through Chi-square and Wilcoxon rank-sum tests, respectively. The odds ratio and confidence interval were calculated as well.

Results:
No significant differences observed between demographic characteristics of the case and control groups. The QF-CMV assay turned reactive (QF-CMV [+]) Women with preeclampsia had lower mean IFN-γ levels in antigen tube compared with normal pregnant controls. There were no statistically significant differences in the value of mitogen tube between case and controls women with suppressed CMV-CMI were 6.3 times more likely to have preeclampsia. This result even strengthened after adjustment for age, gestational age, and gravidity.

Conclusions:
Our findings support an association between suppressed CMV-specific CMI and preeclampsia.
Magnesium Supplementation May Not Be Protective Against Carboplatin-Induced Nephrotoxicity But May Be Beneficial for Children Suffering Malignancies: A Randomized Clinical Trial
Authors: Alizadeh Hadadhania Marzie , Ghaffari Kazem , Absalan Abdorrahim , Eghbali Aygin , Rahimi Afzal Roghayeh , Ghasemi Ali , Eghbali Aziz 
Published: February 2023

Background:
Magnesium oxide may be effective in renal insufficiency prevention after carboplatin therapy. We have evaluated magnesium oxide impression on the serum creatinine (Cr) and blood urea nitrogen (BUN) levels plus glomerular filtration rate (GFR) in cancerous children.

Materials and Methods:
A group of children with different cancers (n = 18) was treated with 250 mg/day magnesium oxide supplementation (MOS) and compared with a matched placebo-treated group (n = 18). After 2 weeks, carboplatin chemotherapy started. We compared serum Cr, BUN, and GFR values before and 3 and 7 days post intervention.

Results:
Serum Cr and BUN were increased significantly 3 and 7 days after intervention in both the groups. Serum Cr and BUN were not statistically different between the MOS and placebo groups before the intervention and 3 or 7 days after carboplatin administration (P > 0.05). Three days after the intervention, the GFR reduced from 101.38 ± 14.67 to 90.11 ± 10.52 mL/min/1.73 m2 in the MOS group. Furthermore, in the placebo group, 3 days after the intervention, the GFR was reduced from 97.5 ± 9.71 to 92.33 ± 10.61 mL/min/1.73 m2. Further, in the MOS group, after 7 days of the intervention, the GFR was reduced to 84.11 ± 12.47 mL/min/1.73 m2. In the placebo group, after 7 days of the intervention, the GFR was diminished to 85.38 ± 10.66 mL/min/1.73 m2 (P = 0.371).

Conclusion:
The current study suggests that magnesium supplementation does not prevent carboplatin-induced nephrotoxicity in children with malignancies. Anyway, we propose magnesium oxide supplementation for this group of pediatrics because magnesium is an essential element for cell and tissue growth, maintenance, and metabolism.
