Multifunctional Space-Time Modulated Metasurface for Direction of Arrival Estimation and RCS Manipulation in a Single System
Authors: Li Mengmeng , Ramaccia Davide , Bilotti Filiberto , Toscano Alessandro 
Published: November 2023

<p> In this paper, we propose a multifunctional space-time modulated metasurface (STM-MTS) able to perform simultaneously a direction of arrival (DoA) estimation and radar cross section (RCS) manipulation in a single system. The metasurface consists of an alignment of unit-cells, whose scattering response can be dynamically controlled to be transparent (full transmissive unit-cell) or opaque (full reflective unit-cell), according to the amplitude of the modulating signal applied to the loading PIN diodes. The DoA estimation is performed behind the metasurface, i.e., in the transmission region, where multi-order harmonics of the incident field whose complex amplitudes are proportional to the DoA is transmitted. The multiple signal classification (MUSIC) algorithm is employed to estimate DoA. Simultaneously, the mono-/bi-static RCSs manipulation is performed in front of the metasurface, i.e. in the reflection region, where the reflected field is properly tailored by controlling the modulation scheme at unit-cell level. An X-band STM-MTS is fabricated to experimentally verify the feasibility of the proposed design. A DoA estimation errors are less than 2° in the incidence angular range of [-50°, +50°] is demonstrated, whereas mono-static and bi-static RCS manipulations of about 17dB and 36dB are achieved at operative frequency. </p>

Published: November 2023

<p>Non-orthogonal multiple access (NOMA) has been proposed as an efficient way to support the massive number of users and devices in sixth generation (6G) networks. As the interest for NOMA- based communication has increased in recent years, it is important to analyze the network performance under interference-limited scenarios. In this paper, the detrimental effect of co-channel interference (CCI) arising from NOMA transmissions on a half-duplex (HD)/full-duplex (FD) relay-aided NOMA network is examined. More specifically, a limited number of randomly deployed CCI terminals communicate using NOMA and degrade the reception of the relay and the users. Network performance is analyzed in terms of outage probability, error probability, throughput, spectral, and energy efficiencies, considering independent and identically distributed non-orthogonal CCI. Furthermore, aiming to improve the network performance, the optimization of the transmit power, power allocation coefficient, and relay location is presented. Our analytical findings are verified through Monte-Carlo-based simulations, revealing that non-orthogonal CCI can severely degrade the system performance. </p>

Published: November 2023

Background: Recent studies have highlighted the possible role of vitamin D in atopic dermatitis (AD) so that it can be used as therapeutical of AD. The aim of study to evaluate the effect of vitamin D supplementation as add-on therapy in adult patients with AD.
Methods: Twenty-four adult patients with AD were included in a randomized, double-blind, placebo-controlled trial study. This study was conducted in Dr. Moewardi General Hospital Surakarta, Indonesia, from February to March 2023. Subjects were randomly assigned to oral cholecalciferol 5,000 IU/day versus placebo for 4 weeks and all subjects were given emollient. The severity of AD was evaluated by using scoring of atopic dermatitis (SCORAD) before and after the trial.
Results: Compared to placebo, vitamin D supplementation for 1 month obtained clinically and statistically improvement in SCORAD score compare to control (-4.508 : 4.500, p= 0.000). Moreover, vitamin D supplementation had strong negative correlation to SCORAD score after the trial (r= -0.780, p= 0,000). There were no adverse effects in either group. and
Conclusion: Clinical improvement was achieved after vitamin D supplementation as add-on therapy in adult patients with AD.
Evidence of task-triggered retrieval of the previous response: a binding perspective on response-repetition benefits in task switching

Published: November 2023

AbstractIn task switching, response repetitions (RRs) usually yield performance benefits as compared to response switches, but only when the task also repeats. When the task switches, RR benefits vanish or even turn into costs, yielding an interaction between repeating versus switching the task and the response (the RR effect). Different theoretical accounts for this RR effect exist, but, in the present study, we specifically tested a prediction derived from binding and retrieval accounts. These maintain that repeating the task retrieves the previous-trial response, thus causing RR benefits. Retrieval is possible due to the task-response binding formed in the previous trial. We employed a task-switching paradigm with three response options that allowed us to differentiate error types. Across two experiments (N = 46 and N = 107) we showed that response-repetition errors in response-switch trials were more likely in task repetitions than in task switches, supporting the notion that the previous response is retrieved by the repeating task, despite being wrong. Such a finding is in line with binding and retrieval accounts but cannot be easily accommodated by the competing theoretical accounts. Thus, the present study indicates task-response binding as an important mechanism underlying RR benefits in task repetitions.

Abstract
Aim: To evaluate the effect of monocyte count and monocyte-based whole blood cell indices in the prediction of intrahepatic cholestasis of pregnancy (ICP) in the first trimester.
Materials and Method: The clinical data of patients who presented to the Perinatology Clinic of the Turkish Ministry of Health ----xxxxxxx--- ICP between January 1, 2021, and October 1, 2022, were evaluated retrospectively. Maternal demographic parameters, gestational age at birth, fetal birth weight, first-trimester white blood cell, neutrophil, platelet, monocyte, lymphocyte, and basophil counts, lymphocyte-to-monocyte ratio (LMR), platelet-to-monocyte ratio (PMR), neutrophil-to-monocyte ratio (NMR), and basophil-to-monocyte ratio (BMR) were recorded. These parameters were compared between the ICP and control groups. The relationship between monocyte count, monocyte-based blood cell indices, and fasting bile acid levels was evaluated in the ICP group. The cut-off values of the first-trimester monocyte count and monocyte-based blood cell indices for the prediction of ICP were determined.
Results: Gestational week at birth and fetal birth weight were significantly lower, and the neonatal intensive care requirement was significantly higher in the ICP group (p

Abstract
We present temporal and time-resolved spectral analyses of all the thermonuclear X-ray bursts observed from the neutron star low-mass X-ray binary 4U 1728−34 with NICER from 2017 June to 2019 September. In total, we detected 11 X-ray bursts from the source and performed time-resolved spectroscopy. Unlike some of the earlier results for other bursting sources from NICER, our spectral results indicate that the use of a scaling factor for the persistent emission is not statistically necessary. This is primarily a result of the strong interstellar absorption in the line of sight toward 4U 1728−34, which causes the count rates to be significantly lower at low energies. We also searched for burst oscillations and detected modulations in six different bursts at around the previously known burst oscillation frequency of 363 Hz. Finally, we report the detection of oscillations prior to two bursts at 356 and 359 Hz, respectively. This is the first time in the literature where burst oscillations are detected before the rapid rise in X-ray flux, from any known burster. These oscillations disappear as soon as the burst starts to rise and occur at a somewhat lower frequency than the oscillations we detect during the bursts.

Abstract
Observations of high-redshift galaxies provide a critical direct test to the theories of early galaxy formation, yet to date, only three have been spectroscopically confirmed at z > 12. Due to strong gravitational lensing over a wide area, the galaxy cluster field A2744 is ideal for searching for the earliest galaxies. Here we present JWST/NIRSpec observations of two galaxies: a robust detection at

. The galaxies are discovered in JWST/NIRCam imaging and their distances are inferred with JWST/NIRSpec spectroscopy, all from the JWST Cycle 1 UNCOVER Treasury survey. Detailed stellar population modeling using JWST NIRCam and NIRSpec data corroborates the primeval characteristics of these galaxies: low mass (∼108
M
⊙), young, rapidly assembling, metal-poor, and star-forming. Interestingly, both galaxies are spatially resolved, having lensing-corrected rest-UV effective radii on the order of 300–400 pc, which are notably larger than other spectroscopically confirmed systems at similar redshifts. The observed dynamic range of z ≳ 10 sizes spans over 1 order of magnitude, implying a significant scatter in the size–mass relation at early times. Deep into the epoch of reionization, these discoveries elucidate the emergence of the first galaxies.
Risques, contre-expertise et démocratie industrielle : Jean Jaurès et les délégués mineurs à la sécurité
Authors: Cabot Bastien 
Published: November 2023

Cet article revient sur le rôle joué par Jean Jaurès dans l’élaboration et l’adoption de la loi du 8 juillet 1890 relative aux délégués à la sécurité des ouvriers mineurs, ou délégués mineurs. Dans un premier temps, l’article revient sur les conditions de travail dans les mines françaises au xix e siècle. Il montre ensuite comment émerge par en bas une revendication de contre-expertise ouvrière portant sur les accidents, visant à contester l’autorité des ingénieurs, et rappelle les oppositions politiques et techniques auxquelles les mineurs font face. Enfin, l’article inscrit le positionnement de Jaurès dans les débats parlementaires qui débutent en 1883, et en montre l’originalité en insistant sur le rôle central que joue la prise de position de Jaurès dans ses futures réflexions autour de la notion de « démocratie industrielle ».
Workplace Commitment Revisited: Adaptation and Cross-Cultural Validation of a New Measurement Scale in a Francophone Context
Authors: Lacroux Alain 
Published: November 2023

L’implication (ou engagement) au travail est un concept clé pour les chercheurs en comportement organisationnel et pour les praticiens car il aide à prévoir des comportements très recherchés dans les organisations contemporaines, tels que l’intention de départ, l’assiduité ou les comportements de citoyenneté organisationnelle. La recherche est toujours active dans ce domaine : la prédominance de l’approche tridimensionnelle de l’engagement initialement proposée par Meyer et Allen (1991) a été régulièrement remise en question, et d’autres propositions ont vu le jour. L’une d’entre elles s’attache à redéfinir le concept clé d’implication dans un format concis et précis (Klein et al. , 2012, 2014). Cette nouvelle approche s’accompagne d’un instrument de mesure compact et polyvalent (KUT : Klein et al., Unidimensional Target free measure of commitment ). L’objectif de cet article est de démontrer l’intérêt de cette nouvelle définition de l’implication, et de contribuer à la validation de l’échelle KUT en contexte français. Nous avons réalisé cette opération en plusieurs étapes, en mobilisant cinq échantillons comprenant un total de 2096 salariés issus de quatre pays francophones (France, Suisse, Belgique et Canada). Nous montrons que la version française de l’échelle KUT présente des propriétés psychométriques adéquates et une invariance culturelle entre les quatre sous-échantillons.
Les errances du team building . Quand les jeunes diplômés dénoncent les absurdités des séminaires de cohésion
Authors: Simon Thomas , Philippe Xavier 
Published: November 2023

Depuis les années 1980, les sessions de team building ont fleuri dans les entreprises jusqu’à devenir des solutions prêtes à l’emploi qui ont malheureusement tendance à faire fuir les meilleurs collaborateurs. Entre mode managériale et volonté d’esthétiser le quotidien des salariés, le team building n’a pas toujours les effets escomptés sur la cohésion des équipes. À l’inverse, l’injonction permanente au fun sur lesquelles ces sessions reposent a un effet contre-productif sur les participants. En brouillant les cartes entre amusement et travail, le team building peut faire surgir des sentiments de dissonance chez les collaborateurs, sources d’inconfort et de malaise. En nous appuyant sur 35 entretiens réalisés auprès de jeunes diplômés de Grandes Écoles de commerce et d’ingénieurs françaises, cette recherche nous permet de mettre en évidence les apories de ces séminaires de cohésion. Le recueil du vécu des participants montre sans concession les limites du team building tel qu’il est organisé traditionnellement. Ceux-ci insistent particulièrement sur le caractère souvent « ridicule » de ces moments censés leur permettre de vivre une expérience amusante et inoubliable. De façon paradoxale, certains soulignent l’émergence d’une connivence dans la gêne partagée. Pour autant, ils ne rejettent pas en bloc le principe même du team building et proposent de nouvelles manières d’organiser ces sessions. Celles-ci doivent notamment être basées sur des temps de rencontre ad hoc et informels impulsés par les salariés eux-mêmes. En d’autres termes, le team building doit être envisagé comme une anecdote sympathique, sans grandiloquence, ni attentes démesurées quant à la structuration du collectif.
Anthropocène, management et sociétés : pour une ouverture anthropologique des sciences de gestion
Authors: Chanlat Jean-François 
Published: November 2023

En ce contexte de crise environnementale et sociétale, l’enseignement et la recherche en sciences de gestion se doivent de contribuer à fournir des réponses adéquates aux différents défis qui se posent à l’Humanité. Pour ce faire, on les somme de poursuivre trois grands objectifs : prendre en compte la dimension transdisciplinaire de tout fait managérial étudié, se soucier de sa pertinence en contexte et se préoccuper de ses effets sur les sociétés concernées. C’est dans ce cadre que la rédaction de RIPCO a invité l’auteur à revenir sur ces questions sous la forme d’un point de vue. Ce point de vue part de la perspective anthropologique de l’auteur qui vient d’être à nouveau exposé dans deux ouvrages récents. Il se divise en quatre parties. Dans la première, l’auteur aborde le contexte, les enjeux et les défis qu’entraînent les crises, environnementale et sociétale, dans lesquelles nous sommes. Dans la deuxième, il souligne la nécessité d’encourager la transdisciplinarité pour aborder les problèmes complexes auxquels la gestion est confrontée aujourd’hui, et invite pour ce faire les chercheurs à s’appuyer sur des perspectives et des méthodologies variées, et sur un multilinguisme raisonné. Dans la troisième, il insiste sur la nécessité de repenser les approches traditionnelles du management pour répondre à ces défis, et promouvoir ainsi des pratiques managériales innovantes et adaptées aux enjeux contemporains. Enfin, dans la dernière partie, il met en avant les courants de recherche actuels en gestion, notamment de langue française, qui peuvent contribuer de manière positive à la durabilité, la justice et la responsabilité sociale qu’exigent les défis actuels propres à l’Anthropocène.

ABSTRACT.
Chagas disease (CD) is a parasitic infection caused by the parasite Trypanosoma cruzi. Reports of CD cases associated with oral transmission have increased, particularly in Colombia, Brazil, and Venezuela. In this investigation, parasitological, serological, and molecular tests were conducted on samples obtained from humans, mammal reservoirs, and hosts involved in the assessment of a suspected oral transmission outbreak in Cubara, Boyaca, Colombia. Seropositivity was observed in 60% (3 of 5) of index patients and 6.4% (5 of 78) of close contacts. Trypanosoma cruzi DNA was detected by quantitative polymerase chain reaction in 100% of index cases, 6.4% (5 of 78) of close contacts, 60% (6 of 10) of canines, and 100% (5 of 5) of opossums. In all index cases, the TcI lineage was identified, along with two cases of mixed infection (TcI/TcII–TcVI). Hemoculture revealed a flagellate presence in 80% of opossums, whereas all triatomine bugs tested negative. Our findings suggest a potential oral transmission route through contamination with opossum secretions.

Published: November 2023

Gastro retentive delivery systems are designed to be retained in the stomach for a prolonged time and release their active ingredients and thereby enable sustained and prolonged input of the drug to the upper part of the gastrointestinal (GI) tract. The goal of any drug delivery system is to provide a therapeutic amount of drug to proper site in the body to achieve promptly and then maintain a desired drug concentration. Baclofen is a gamma-aminobutyric acid (GABA) agonist used as a skeletal muscle relaxant used for the relief of painful and uncomfortable muscle spasms caused by a variety of conditions. Twelve different formulation of Baclofen floating beads were successfully developed using emulsion solvent diffusion method. The beads had good yield and showed high, drug entrapment efficiency. The flow properties of beads were within the acceptable range and therefore would be easily filled into capsules.
Study concludes successfully delivery of Baclofen by the means of floating beads.
