Imaging the Sun’s Near-surface Flows Using Mode-coupling Analysis
Authors: Mani Prasad , Hanson Chris S. , Hanasoge Shravan 
Published: February 2022

Abstract
The technique of normal-mode coupling is a powerful tool with which to seismically image non-axisymmetric phenomena in the Sun. Here we apply mode coupling in the Cartesian approximation to probe steady, near-surface flows in the Sun. Using Doppler cubes obtained from the Helioseismic and Magnetic Imager on board the Solar Dynamics Observatory, we perform inversions on mode-coupling measurements to show that the resulting divergence and radial vorticity maps at supergranular length scales (∼30 Mm) near the surface compare extremely well with those obtained using the local correlation tracking method. We find that the Pearson correlation coefficient is ≥0.9 for divergence flows, while ≥0.8 is obtained for the radial vorticity.
Quantifying the Projected Suppression of Cluster Escape Velocity Profiles
Authors: Halenka Vitali , Miller Christopher J. , Vansickle Paige 
Published: February 2022

Abstract
The 3D radial escape-velocity profile of galaxy clusters has been suggested to be a promising and competitive tool for constraining mass profiles and cosmological parameters in an accelerating universe. However, the observed line-of-sight escape profile is known to be suppressed compared to the underlying 3D radial (or tangential) escape profile. Past work has suggested that velocity anisotropy in the phase-space data is the root cause. Instead, we find that the observed suppression is from the statistical undersampling of the phase spaces and that the 3D radial escape edge can be accurately inferred from projected data. We build an analytical model for this suppression that only requires the number of observed galaxies N in the phase-space data within the sky-projected range 0.3 ≤ r
⊥/R
200,critical ≤ 1. The radially averaged suppression function is an inverse power law

Origins of Hot Jupiters from the Stellar Obliquity Distribution
Authors: Rice Malena , Wang Songhu , Laughlin Gregory 
Published: February 2022

Abstract
The obliquity of a star, or the angle between its spin axis and the average orbit normal of its companion planets, provides a unique constraint on that system’s evolutionary history. Unlike the solar system, where the Sun’s equator is nearly aligned with its companion planets, many hot-Jupiter systems have been discovered with large spin–orbit misalignments, hosting planets on polar or retrograde orbits. We demonstrate that, in contrast to stars harboring hot Jupiters on circular orbits, those with eccentric companions follow no population-wide obliquity trend with stellar temperature. This finding can be naturally explained through a combination of high-eccentricity migration and tidal damping. Furthermore, we show that the joint obliquity and eccentricity distributions observed today are consistent with the outcomes of high-eccentricity migration, with no strict requirement to invoke the other hot-Jupiter formation mechanisms of disk migration or in situ formation. At a population-wide level, high-eccentricity migration can consistently shape the dynamical evolution of hot-Jupiter systems.
Sorcières

L’article explore la revue française Sorcières (1975-1982) dans une double perspective, à la fois textometrique et littéraire. Dans une première partie, « L’architecture thématique de la revue Sorcières », nous nous proposons de décrire le projet éditorial, littéraire et politique de Sorcières par une analyse assistée par ordinateur des thèmes de la revue : dans cette méthode, les proximités entre les mots sont observées de façon à élaborer des classes de vocabulaire, qui suggèrent les thématiques principales de la revue. Dans une deuxième partie « Le numéro 1 : de l’alimentation aliénante à la nourriture libératrice » nous voulons nous pencher plus précisément sur le numéro 1 de la collection, considéré comme un manifeste pour l’expression et la création féminines et consacré à la nourriture. Par l’analyse littéraire et critiques des textes des contributrices, l’image de la nourriture, dans ce premier dossier, n’apparaît jamais comme un élément de contrainte pour les femmes mais se révèle être à la fois moyen de connaissance et un lien avec leurs corps.
Femmes, éducation et politique
Authors: Rodríguez Serrador Sofía , Charbin Coline 
Published: February 2022

À partir des années vingt, les femmes espagnoles ont participé de façon de plus en plus active dans la sphère publique du fait d’un processus d’acquisition d’un niveau culturel plus élevé et de changements dans la mentalité de la société, passant à revendiquer une série de droits politiques et sociaux : accès à l’éducation, au vote, au divorce… Lors de ces premières décennies, les espaces culturels clairement féminins qui ont été créés ont favorisé ces débats et ont consolidé des liens de sororité, comme la Residencia de Señoritas ou le Lyceum Club . À leur tour, ces femmes ont aidé à consolider des nouveaux modèles de genre alternatifs voire même opposés au rôle féminin traditionnel. Cependant, les « femmes modernes » ont rencontré des forts noyaux de résistance, non seulement parmi les éléments les plus conservateurs de la société, mais aussi parmi les intellectuels. Dans cet article nous étudierons la façon dont les revues féministes / féminines ont abordé ces changements et la reconnaissance des droits de la femme.
Arrêt du tabac : une personnalisation nécessaire des programmes de sevrage
Authors: Gallopel-Morvan Karine , Alla François , Bonnay-Hamon Alice , Brousse Philippine , Gonneau Audrey , Castera Philippe 
Published: February 2022

Objectif : Avec 13 millions de fumeurs en France en 2019, le tabagisme reste un enjeu majeur de santé. Le projet « Lieux d’accompagnement à la santé sans tabac » (LAST) mis en place en Nouvelle-Aquitaine a pour but d’inciter les fumeurs à se faire aider pour arrêter le tabac. Méthode : Afin d’identifier les freins au sevrage tabagique et les leviers à mobiliser pour favoriser la demande d’aide de la part des fumeurs puis construire avec eux leur programme de sevrage « idéal », une étude qualitative individuelle à partir d’entretiens semi-directifs a été menée en mai 2019 auprès de 19 fumeurs en contemplation ou préparation (modèle transthéorique). Résultats : Les aides disponibles pour l’arrêt du tabac sont mal connues des fumeurs et par conséquent peu utilisées. Les raisons sont le manque d’information sur leur efficacité, le coût perçu et la peur de développer une autre forme de dépendance. Concernant le programme idéal des fumeurs interrogés, le recours à un professionnel de santé est cité par la majorité d’entre eux, suivi de l’activité physique (pour éviter la prise de poids), des substituts nicotiniques et des autres traitements médicamenteux. La nécessité de combiner les dispositifs et de personnaliser l’offre de sevrage est une demande forte. Conclusion : L’élaboration du programme d’aide à l’arrêt « idéal » et personnalisé semble constituer, pour chaque fumeur, une opportunité pour choisir les aides les plus conformes à ses besoins et valeurs. Les professionnels de premier recours, du fait de leur proximité, apparaissent une entrée clef pour accompagner les tentatives d’arrêt.

Published: February 2022

This study of the COVID-19 online learning experiences of students in a Singaporean higher education institution (HEI) assesses the students’ ‘fit’ (ie, their satisfaction) with online learning, as gauged through the Information Technology (IT) models of Task-Technology Fit (TTF) and Unified Theory of Acceptance and Use of Technology (UTAUT). While current studies have found that curriculum, instructor and learner factors have impacted on students and online learning during COVID-19, it has been observed that there is insufficient understanding of factors that predict students’ online learning satisfaction [24]. This study thus contributes where there are few, if any studies that assess students’ online learning satisfaction through technological models. Furthermore, the study’s finding are that the students’ perception of, general attitude to, and intention to use the online learning shaped their satisfaction, thus pointing to the value of such technological models in understanding student learning at a deeper level. Students’ experiential comments from the study also form recommendations for effective online teaching practice which apply to Singapore, and broadly for higher education (HE) online learning design. Significantly, the information technology (IT) models are shown as valuable in assessing HE students’ online learning satisfaction.
Un passé ravivé. La Commune dans les engagements du présent
Authors: Bantigny Ludivine 
Published: February 2022

Cet article explore l’actualité de la Commune, plus précisément les formes de son actualisation, les manières dont elle est rendue vivante dans un certain nombre d’expériences contemporaines : sa présence au présent. Il s’agit ici de retracer l’histoire de certains courants politiques et de mouvements sociaux qui ne cessent de faire référence à la révolution populaire de 1871. Que retiennent-ils de la Commune ? Comment les enjeux liés à la propriété et aux usages, aux biens communs, à la démocratie, à la justice sociale et à l’égalité puisent-ils dans cet héritage historique ? Sont ici analysés le situationnisme et l’autonomie politique, les Zones à défendre et le soulèvement populaire des Gilets jaunes. Chacun de ces mouvements, mobilisations, organisations indique que la Commune de Paris, anti-autoritaire, fédéraliste, populaire, participative et égalitaire, a encore de quoi inspirer. Ce dont donc les formes de cette inspiration que l’article explore à partir de documents variés.

Published: February 2022

It is vital that the higher education institutes maintain their ability to train undergraduates during the COVID-19 pandemic. Several novel measures were incorporated. The purpose of this article is to share the systematic approach that was taken by FMAS, RUSL during this pandemic. We used a systematic approach for teaching/learning, assessment and faculty development under main categories of1. Leadership/Management of MBBS curriculum: Headed by the Dean of the faculty with support from the Medical Education Unit plays a pivotal role for planning, maintaining and evaluating online education. 2. Teaching/learning: An online teaching guide was developed taking into account the best evidences and contextual constrains. LMS was updated more student friendly 3. Assessment: emphasis on formative assessments 4. Physical and human resources: Focused on competence in using LMS by the staff, online instructional design and providing physical resources. All activities were implemented through a team effort and ongoing evaluations are being done to assess usefulness of these measures. We hope this approach would be a useful reference for similar crisis events in the future.
Factors Affecting Radiographers in the Clinical Supervision of Radiography Students in a Limited Resource Setting: A Survey in Zambia
Authors: Bwanga O. , Sichone J. M. , Kaonga P. 
Published: February 2022

Background and Purpose: Clinical teaching and learning are an important aspect of radiography programmes. It enables radiography students to acquire knowledge, attitudes, skills, and competence under the clinical supervision of designated radiographers. However, there is a paucity of research on radiography clinical training and the factors that impact on it. This study aimed to evaluate factors that affect supervising radiographers in the clinical supervision of radiography students in Zambia. Methods: A cross-sectional design was utilised in this study. A self-administered questionnaire was used to collect data from supervising radiographers (N=120) working in public hospitals affiliated with the schools of radiography and located in the Lusaka and Copperbelt provinces of Zambia. Data were analysed using descriptive and inferential statistical methods. Results: The response rate was 75% (N=120/160). Supervising radiographers rated the current system of clinical supervision as being unsatisfactory. Factors that facilitated the clinical supervision process were an adequate supply of X-ray films, students sharing their learning problems and radiology department management support. On the other hand, factors that inhibited the clinical supervision process were a lack of guidelines, lack of theory amongst students, combined supervision of diploma and degree students, student overcrowding, lack of educational audits, unjustified imaging requests, insufficient clinical teaching knowledge, and inadequate faculty and hospital management supports. Conclusion: Supervising radiographers encounter both facilitating and inhibiting factors in the facilitation of practice-based learning for radiography students. More collaboration amongst key stakeholders and supports are necessary to overcome the challenges identified in this study.
Postphalloplasty urinary function test: an observational study of novel outcome instrument to capture urinary dysfunction and quality of life after phalloplasty

Published: February 2022

ABSTRACT
Due to growing social acceptance, there has been an increasing number of gender-affirmation surgeries performed in North America. Most research in this patient population focuses on surgical outcomes and advancing techniques. However, little work has been done to study functional outcomes. To better evaluate urinary dysfunction in the postphalloplasty trans men patient population, our group developed a novel patient-reported outcome instrument – the postphalloplasty urinary function test (PP UFT) and protocol to measure postvoid urethral volume (PVUR), and we present our preliminary results. We conducted a cross-sectional pilot study in a cohort of 15 adult trans men who had undergone phalloplasty with urethral lengthening surgery between 2018 and 2021. Patients had stable urinary function via the neophallus at the time of survey. Patients filled out the PP UFT and were asked to record their PVUR as per our protocol. The average PP UFT score was 8.9 out of 40 and the average quality-of-life (QOL) score was 2.6. Postvoid dribbling constituted the major complaint and on average comprised 63.2% of the reported PP UFT score. The average PVUR was 2.2 ml (range: 0.5–5.6 ml). There was a positive correlation between higher PP UFT and worse-reported quality of life (P < 0.01; R
2 = 0.4). Current questionnaires accepted in cis-male urology have limitations for accurately capturing urinary dysfunction in this specific patient group. The combination of PP UFT and PVUR measurement offers potential for quantifying urinary function and quality of life in patients who undergo phalloplasty. Future studies will validate these instruments.
Relationship of neck circumference to some cardiometabolic risk parameters
Authors: Fathalla Reem , Lachine Nagwa , Badbess Mohamed , Tahoun Mona , Zeitoun Mohamed 
Published: February 2022

Background
Neck circumference (NC) is an easy and reliable anthropometric measurement. The use of NC as an indicator of obesity among Egyptians was previously established. However, the relationship between NC and different cardiometabolic risk (CMR) parameters was not previously studied in the Egyptian population.

Objective
The aim of this work was to study the relationship between NC and some CMR parameters in obese adult Egyptian individuals.

Participants and methods
This cross-sectional study was carried out on 100 apparently healthy obese adult Egyptian participants (BMI ≥30 kg/m2), above the age of 18 years, 50% of them were males and the other 50% were females. NC and other traditional anthropometric measurements were evaluated. Blood samples were assayed for glycosylated hemoglobin, total cholesterol, high-density lipoprotein cholesterol (HDL-C), non-HDL-C, and high-sensitivity C-reactive protein.

Results
There were significant positive correlations between NC and each of systolic and diastolic blood pressure [(r=0.527, P<0.001), (r=0.430, P<0.001), respectively], waist circumference (r=0.538, P<0.001), BMI (r=0.403, P<0.001), and high-sensitivity C-reactive protein (r=0.304, P=0.002). While a significant negative correlation was found between NC and HDL-C. Multivariate regression analysis revealed an independent association of NC with waist circumference in males and with systolic blood pressure in females.

Conclusion
This study does not only confirm the association of NC with anthropometric measurements in the Egyptian population, but it also establishes the NC association with CMR factors that support the possibility of using NC as a CMR marker among Egyptians.
Computing harmonic maps between Riemannian manifolds
Authors: Gaster Jonah , Loustau Brice , Monsaingeon Léonard 
Published: February 2022

AbstractIn our previous paper (Gaster et al., 2018, arXiv:1810.11932), we showed that the theory of harmonic maps between Riemannian manifolds, especially hyperbolic surfaces, may be discretized by introducing a triangulation of the domain manifold with independent vertex and edge weights. In the present paper, we study convergence of the discrete theory back to the smooth theory when taking finer and finer triangulations, in the general Riemannian setting. We present suitable conditions on the weighted triangulations that ensure convergence of discrete harmonic maps to smooth harmonic maps, introducing the notion of (almost) asymptotically Laplacian weights, and we offer a systematic method to construct such weighted triangulations in the two-dimensional case. Our computer software Harmony successfully implements these methods to compute equivariant harmonic maps in the hyperbolic plane.

Published: February 2022

Background: Diversity is a potential source for immense untapped material wealth in the forms of food, medicine and other amenities. One of these neglected plants is Monkey Cola.
Objective: The study evaluated the effect of Cola pachycarpa and Cola lepidota fruit juices on the liver function parameters (aspartate transaminase, alanine transaminase, alkaline phosphatase & total protein) and histopathological indices (liver tissue) of alloxan- induced diabetic rats.
Materials and methods: Fresh Cola pachycarpa and Cola lepidota fruits were obtained from local markets and home farms within communities in Isiala Mbano local government area of Imo State and Isiala Ngwa South local government area of Abia State. The fruits were processed into raw and undiluted fruit juice using an electric juicer. Forty healthy adult albino male rats with an average weight of 239.35g were randomized into eight groups, six experimental and two control groups, based on body weight. All the rats in each group were induced with alloxan to become diabetic. Samples of blood were collected for use as basal biochemical and hematological indices as well as after induction with diabetes. Standard diabetic drug, glibenclamide and Cola fruit juices (pachycarpa and lepidota) were administered differently and in varied concentrations (5ml/kg and 10ml/kg body weight). The experiment lasted for 21days after which the animals were sedated with mild anesthetic and sacrificed by cervical dislocation. The liver of the animals were excised, packaged, labeled and stored for subsequent chemical analysis and histopathology. Data was analyzed statistically using IBM-SPSS (Special Package for Social Sciences) version 20 software for means and standard deviation.
Results: Monkey Cola fruit juices significantly (p < 0.05) decreased alkaline phosphatase (28.95%, CPV1, Group that received Cola pachycarpa very rough epicarp fruit juice at 5ml/kg body weight), aspartate transaminase (29.81%, CPV1) comparative to those of the standard diabetic drug (29.58% and 17.58% respectively). Histopathological studies indicated abnormal hepatocyte structure in only the untreated group of rats. Rats that received standard diabetic drug reported significant (p < 0.05) better liver architecture from other treatment groups, though damage to the liver was not noticed in rats that received the fruit juices. All the Cola juices especially those administered at 10mls/kg body weight impacted positively in improving body weight, haematological, biochemical and histopathological indices in diabetes control.
Conclusion: Further research could be done to establish its prospect as an anti-diabetic agent.
