Prospérité et infortunes d’un mythe national. Les Gaulois dans le discours public depuis 1958
Authors: Garcia Patrick 
Published: September 2020

Cet article propose d’étudier l’évolution et la réécriture du mythe des Gaulois dans le discours public, à travers les discours présidentiels sous la V e République. Encore vivace sous la présidence de Charles de Gaulle, le mythe perd en force au lendemain des septennats de François Mitterrand, avant d’être trivialisé – Vercingétorix laissant place à Astérix et Obélix – et réactualisé à la faveur du débat sur l’identité française.

Abstract
Over the past decades, many accelerator laboratories have put much effort into the development of compact energy-recovery linac (ERL) demonstrators to verify various physical and technical aspects of the generation, acceleration, transport and energy recovery of high brightness and high average current electron beams in a superconducting radio-frequency (SRF) linear accelerator. Beyond these goals, the ERL demonstrator also offers unique opportunities to study novel schemes for THz and X-ray radiation generation. In this paper, we discuss feasible options for schemes generating THz and X-ray radiation at low-energy continuous-wave (CW) SRF ERL demonstrators such as the bERLinPro accelerator.

Stereotypes Surrounding the Hungarian Peasantry During the Years of the First World War
Authors: Csíki Tamás 
Published: September 2020

The paper examines the use and political, ideological, and social meanings of the term peasant and its synonyms. It reflects on how these meanings were modified as a consequence of the structural and experiential changes in the social situation of the agrarian population. The textual analysis is based on publications from the press during the First World War and, thus, the concepts, in their contexts, can be under­stood first as instruments for propaganda and mental mobilization, that is to say, as political action. Second, these notions and concepts also incorporated past (histor­ical) phenomena and future expectations, through which they offered arguments for programs and ideas to transform society. Third, the texts frequently prompted debates in the media, which strengthened the discursive nature of the press, the controlled publicity, and the usage of vocabulary and language. By the same token, they can also represent a chance to examine the social stereotypes and the experience of personal relations crystallized in these texts.

Published: September 2020

El objetivo principal de las áreas protegidas (AP) es mantener muestras representativas de la biodiversidad. Dado que la biodiversidad en su totalidad es imposible de conservar, usualmente se utilizan especies amenazadas como sustitutas. Bajo esta premisa‚ el propósito del presente trabajo fue evaluarla representatividad de los mamíferos no voladores amenazados en el sistema departamental de áreas protegidas (SIDAP) del Quindío‚ así como identificar áreas importantes para su conservación. Se recopilaron registros de Leopardus tigrinus‚ Tapirus pinchaque‚ Pudu mephistophiles‚Tremarctos ornatus‚ Aotus lemurinus‚ Dinomys branickii y Lontra longicaudis y se estimó su distribución geográfica potencial. La distribución potencial de los mamíferos amenazados estuvo bien representado en el SIDAP Quindío (entre 48% y 100%) excepto para L. longicaudis con el 15‚42% de su distribución incluida en APs‚ que coincide con la poca representatividad de las tierras bajas en el sistema. En cuanto a la zona oriental y nororiental del departamento las oportunidades de conservación in situ son apenas aparentes‚ porque la mayor área corresponde a los Distritos Regional de Manejo Integrado (DRMI) en los municipios de Salento y Génova‚ donde las categorías de manejo son flexibles por lo que se sugeriría un ajuste de su categoría. Se evidencia la necesidad de fortalecer el SIDAP para procurar la conservación de las especies de mamíferos amenazados y aumentar la representación de los ecosistemas de esta zona. En conclusión‚ se recomienda la declaración de AP en zonas bajas del departamento‚ teniendo en cuenta el contexto socioeconómico en la asignación de las categorías de conservación y manejo de las AP. Por su parte, en los DRMI de la cuenca del río Quindío y de los páramos y bosques altoandinos del municipio de Génova, podría considerarse la recategorización de algunas áreas por esquemas más estrictos, especialmente en tierras estatales con áreas decobertura natural.

What Is Wrong With Grade Inflation (if Anything)?
Authors: Finefter-Rosenbluh Ilana , Levinson Meira 
Published: September 2020

Grade inflation is a global phenomenon that has garnered widespread condemnation among educators, researchers, and the public. Yet, few have deliberated over the ethics of grading, let alone the ethics of grade inflation. The purpose of this paper is to map out and examine the ethics of grade inflation. By way of beginning, we clarify why grade inflation is a problem of practical ethics embedded in contemporary social practice. Then, we illuminate three different aspects of grade inflation—longitudinal, compressed, and comparative—and explore the ethical dilemmas that each one raises. We demonstrate how these three aspects may be seen as corresponding to three different victims of grade inflation—individuals, institutions, and society—and hence also to three potential agents of harm—teachers, schools, and educational systems. Next, we reflect upon various compelling reasons that these agents inflate grades, whether from an ethic of care, fiduciary responsibility, or simple self-preservation. Subsequently, we consider a variety of means of combatting grade inflation, and invite more educators and philosophers to delve into the complex practical ethics of grade inflation.

Published: July 2002

AbstractObjective: To compare vaginal versus oral misoprostol for induction of labor. Method: Induction of labor was carried out in 40 women near term in two equal and randomized groups (according to a computer generated table) using misoprostol. Group I received vaginal misoprostol (100 μg) every 3 h while group II patients were given the same dose via the oral route. The dose was doubled if no response was detected under continuous cardiotocographic (CTG) tracings. Result: The vaginal route of administration induced a higher success rate in a shorter time interval using a lower dose but was associated with more abnormal FHR patterns and instances of uterine hyperstimulation. Conclusion: It is recommended to use the vaginal approach with cardiotocographic monitoring.
Cholinesterases modulate cell adhesion in human neuroblastoma cells in vitro
Authors: Johnson Glynis , Moore Samuel W. 
Published: July 2002

AbstractCholinesterases are expressed non‐synaptically during embryonic development, neoplasia and neurodegeneration. We have investigated the effects of acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) and, conversely, anti‐AChE and ‐BChE antibodies and inhibitors on cell adhesion and neurite outgrowth in human neuroblastoma cells. Analysis of cholinesterase levels and isoforms in undifferentiated and differentiated cells indicated a significant rise in AChE levels on differentiation. This increase was related to both cell‐associated and secreted enzyme, and was predominantly the G4 isoform. BChE levels and isoforms, on the other hand, showed no significant variation. Coating the tissue culture plate with AChE stimulated neurite outgrowth, while BChE had an anti‐adhesive effect. Cell adhesion was affected by the BChE inhibitor, ethopropazine, and the AChE peripheral site inhibitor, BW284c51, but not by eserine which binds to the active site. This indicates that the adhesion function is non‐cholinergic, a finding supported by the lack of effect of AE‐2, a monoclonal antibody that inhibits AChE, on cell adhesion. Four out of a panel of nine anti‐AChE antibodies inhibited adhesion to varying degrees. Of these antibodies, two are catalytic, with epitopes associated with the peripheral anionic site of AChE, and the remaining two have epitopes overlapping this site. Neither of the two anti‐BChE antibodies used had any effect on adhesion. These results indicate the importance of AChE in neuroblastoma cell adhesion and neurite outgrowth, and suggest that the peripheral anionic site may be involved in these processes.
The distribution of radiolabeled corticotropin‐releasing factor in pregnant rats : an investigation of placental transfer to the FETUSES
Authors: Williams Michael T. , Davis Harry N. , Mccrea Anne E. , Hennessy Michael B. 
Published: July 2002

AbstractStress during gestation can have serious consequences on the development of the fetus. Many of these effects appear to be mediated by hormones of the hypothalamic‐pituitary‐adrenal (HPA) axis. Corticotropin‐releasing factor (CRF), released by the hypothalamus during times of stress serves to activate release of pituitary hormones and is also present in low levels in rat plasma. Moreover, the uterus contains significant quantities of CRF at implantation sites, probably from local sources. Therefore, the possibility exists that CRF may cross the placenta and activate the fetal HPA axis. However, the ability of CRF to cross the placenta has not been demonstrated. In the present study, pregnant rats were administered radiolabeled CRF intraperitoneally, and the distribution of the labeled product was determined in the fetuses and various maternal organs. High levels of activity were observed in the pregnant females uterus, adrenals, heart and the placentae, but only background levels of activity were detected in the maternal brain. Very low levels of activity were observed in the fetuses, indicating that the transfer of CRF across the placenta is greatly restricted. These findings suggest that maternal CRF has little or no direct effect on the developing fetus during gestational stress.
Consequences of Recent Changes in Research and Practice for the Identity of Psychiatrists
Authors: Guimón J 
Published: July 2002

SummaryThe limits of the role of psychiatrists are becoming increasingly vague as a consequence of the confusion on the theoretical model, the excessive size of the field and the managed care movement that is deeply altering the way psychiatric services are delivered. A thorough reflection has to be made about the need to strengthen the professional identity of future psychiatrists in the course of their training. Theoretical orientation of psychiatrists depends, to a large extent, on the training that they received during residency and the type of practice they undertake. It is necessary, therefore, to consider that the institutional path and expected activities in the program of training postgraduates is particularly important for the development of the identity of the resident as a psychiatrist. The criteria for elaborating these programs have to take into account, not only the opinion of the teachers and of the residents, but also many other parameters, one of which is the description of what makes a true psychiatrist in his or her clinical practice, so as to adapt the content of programs to the realization of inherent objectives to the activities described.

Published: September 2020

AbstractThin‐film supercapacitors are promising candidates for energy storage in wearable electronics due to their mechanical flexibility, high power density, long cycling life, and fast‐charging capability. In addition to all of these features, device transparency would open up completely new opportunities in wearable devices, virtual reality or in heads‐up displays for vehicle navigation. Here a method is introduced for micromolding Ag/porous carbon and Ag/NixFeyOz@reduced graphene oxide (rGO) into grid‐like patterns on polyethylene terephthalate foils to produce transparent thin‐film supercapacitors and hybrid supercapacitors. The supercapacitor delivers a high areal capacitance of 226.8 µF cm−2 at a current density of 3 µA cm−2 and with a transparency of 70.6%. The cycling stability is preserved even after 1000 cycles under intense bending. A hybrid supercapacitor is additionally fabricated by integrating two electrodes of Ag/porous carbon and Ag/NixFeyOz@rGO. It offers an areal capacitance of 282.1 µF cm−2 at a current density of 3 µA cm−2, a transparency of 73.3% and the areal capacitance only decreases slightly under bending. This work indicates that micromolding of nano‐ and micro‐sized powders represents a powerful method for preparing regular electrode patterns, which are fundamental for the development of transparent energy storage devices.

Published: September 2020

AbstractNonfullerene acceptors (NFAs) are a current focus of research on bulk‐heterojunction organic solar cells (OSCs), as they can exhibit strong absorption, suitably matched energy levels, and good stability. Isomerization affords a new material design strategy for nonfullerene small‐molecule acceptors (SMAs). In this article, the development of isomeric nonfullerene SMAs, including isomeric perylene diimide (PDI)‐based nonfullerene SMAs and isomeric acceptor–donor–acceptor (A–D–A)‐type nonfullerene SMAs, is reviewed. The general design principles for isomeric SMAs and the key structure–property relationships are comprehensively surveyed and discussed. The remaining challenges and promising future directions of isomeric nonfullerene acceptors are presented.

AbstractCharge recombination due to interfacial defects is an important source of loss in perovskite solar cells. Here, a two‐sided passivation strategy is implemented by incorporating a bilinker molecule, thiophene‐based carboxylic acid (TCA), which passivates defects on both the perovskite side and the TiO2 side of the electron‐extracting heterojunction in perovskite solar cells. Density functional theory and ultrafast charge dynamics reveal a 50% reduction in charge recombination at this interface. Perovskite solar cells made using TCA‐passivated heterojunctions achieve a power conversion efficiency of 21.2% compared to 19.8% for control cells. The TCA‐containing cells retain 96% of initial efficiency following 50 h of UV‐filtered MPP testing.
Sequential Protein Capture in Multiplex Single Molecule Arrays: A Strategy for Eliminating Assay Cross‐Reactivity

Published: September 2020

AbstractMeasurements of multiple biomolecules within the same biological sample are important for many clinical applications to enable accurate disease diagnosis or classification. These disease‐related biomarkers often exist at very low levels in biological fluids, necessitating ultrasensitive measurement methods. Single‐molecule arrays (Simoa), a bead‐based digital enzyme‐linked immunosorbent assay, is the current state of the art for ultrasensitive protein detection and can detect sub‐femtomolar protein concentrations, but its ability to achieve high‐order multiplexing without cross‐reactivity remains a challenge. Here, a sequential protein capture approach for multiplex Simoa assays is implemented to eliminate cross‐reactivity between binding reagents by sequentially capturing each protein analyte and then incubating each capture bead with only its corresponding detection antibody. This strategy not only reduces cross‐reactivity to background levels and significantly improves measurement accuracies, but also enables higher‐order multiplexing. As a proof of concept, the sequential multiplex Simoa assay is used to measure five different cytokines in plasma samples from Coronavirus Disease 2019 (COVID‐19) patients. The ultrasensitive sequential multiplex Simoa assays will enable the simultaneous measurements of multiple low‐abundance analytes in a time‐ and cost‐effective manner and will prove especially critical in many cases where sample volumes are limited.
One‐shot video‐based person re‐identification with variance subsampling algorithm

Published: September 2020

AbstractPrevious works propose the distance‐based sampling for unlabeled datapoints to address the few‐shot person re‐identification task, however, many selected samples may be assigned with wrong labels due to poor feature quality in these works, which negatively affects the learning procedure. In this article, we propose a novel sampling strategy to improve the quality of assigned pseudo‐labels, thus promoting the final performance. To illustrate, we first propose the concept of variance confidence to measure the credibility of pseudo‐labels, then we apply a novel variance subsampling algorithm to improve the accuracy of the selected sample labels. Our method combines distance confidence and variance confidence as a two‐round sampling criterion. Meanwhile, a variation decay strategy is used in our sampling process in combination with the actual distribution of features. We evaluate our approach on two publicly available datasets, MARS and DukeMTMC‐VideoReID, and achieve state‐of‐the‐art one‐shot performance.
Design procedure for planar slotted waveguide antenna arrays with controllable sidelobe level ratio for high power microwave applications
Authors: El Misilmani Hilal M. , Al‐Husseini Mohammed , Kabalan Karim Y. 
Published: September 2020

SummaryThis article presents a complete design procedure for planar slotted waveguide antennas (SWA). For a desired sidelobe level ratio (SLR), the proposed method provides a pencil shape pattern with a narrow half power beamwidth, which makes the proposed system suitable for high power microwave applications. The proposed planar SWA is composed of only two layers, and uses longitudinal coupling slots rather than the conventional inclined coupling slots. For a desired SLR, the slots excitation in the radiating and feeder SWAs are calculated based on a specified distribution. Simplified closed‐form equations are then used to determine the slots nonuniform displacements, for both the radiating and feeder SWAs, without the need to use optimization algorithms. Using simplified equations, the slots lengths, widths, and their distribution along the length of the radiating and feeder SWAs can be found. The feeder dimensions and slots positions are deduced from the dimensions and total number of the radiating SWAs. An 8 × 8 planar SWA has been designed and tested to show the validity of the proposed method. The obtained measured and simulated results are in accordance with the design objectives.
