The Origin of Star-forming Rings in S0 Galaxies
Authors: Tous J. L. , Domínguez-Sánchez H. , Solanes J. M. , Perea J. D. 
Published: January 2023

Abstract
Spatially resolved integral field spectroscopic maps in a sample of 532 S0 galaxies from the MaNGA survey have unveiled the existence of inner rings (〈R〉 ∼ 1 R
e) betraying ongoing star formation in a number of these objects. Activity gradients averaged over bins of galactocentric radius up to ∼1.5 R
e have been measured in the subspace defined by the first two principal components of the optical spectra of these galaxies. We find that the sign of the gradients is closely related to the presence of such rings in the spectral maps, which are especially conspicuous in the equivalent width of the Hα emission line, EW(Hα), with a fractional abundance—21%–34%—notably larger than that inferred from optical images. While the numbers of S0s with positive, negative, and flat activity gradients are comparable, star-forming rings are largely found in objects for which quenching proceeds from the inside out, in good agreement with predictions from cosmological simulations studying S0 buildup. Assessment of these ringed structures indicates that their frequency increases with the mass of their hosts, that they have shorter lifetimes in galaxies with ongoing star formation, that they may feed on gas from the disks, and that the local environment does not play a relevant role in their formation. We conclude that the presence of inner rings in EW(Hα) is a common phenomenon in fully formed S0s, possibly associated with annular disk resonances driven by weakly disruptive mergers preferentially involving a relatively massive primary galaxy and a tiny satellite strongly bound to the former.
Black Hole Images as Tests of General Relativity: Effects of Spacetime Geometry
Authors: Younsi Ziri , Psaltis Dimitrios , Özel Feryal 
Published: January 2023

Abstract
The images of supermassive black holes surrounded by optically thin, radiatively inefficient accretion flows, like those observed with the Event Horizon Telescope, are characterized by a bright ring of emission surrounding the black hole shadow. In the Kerr spacetime, this bright ring, when narrow, closely traces the boundary of the shadow and can, with appropriate calibration, serve as its proxy. The present paper expands the validity of this statement by considering two particular spacetime geometries: a solution to the field equations of a modified gravity theory and another that parametrically deviates from Kerr but recovers the Kerr spacetime when its deviation parameters vanish. A covariant, axisymmetric analytic model of the accretion flow based on conservation laws and spanning a broad range of plasma conditions is utilized to calculate synthetic non-Kerr black hole images, which are then analyzed and characterized. We find that in all spacetimes: (i) it is the gravitationally lensed unstable photon orbit that plays the critical role in establishing the diameter of the rings observed in black hole images, not the event horizon or the innermost stable circular orbit, (ii) bright rings in these images scale in size with, and encompass, the boundaries of the black hole shadows, even when deviating significantly from Kerr, and (iii) uncertainties in the physical properties of the accreting plasma introduce subdominant corrections to the relation between the diameter of the image and the diameter of the black hole shadow. These results provide important new theoretical justification for using black hole images to probe and test the spacetimes of supermassive black holes.

Soumises, les filles en bac pro ?
Authors: Depoilly Séverine 
Published: January 2023

À partir d’une enquête ethnographique conduite dans un lycée professionnel agricole, dans une filière accueillant majoritairement des filles et au recrutement populaire, cet article propose de s’intéresser aux manières variées et parfois hétérodoxes dont les lycéennes s’approprient leur trajectoire scolaire et leurs expériences de formation. Nous montrons que loin d’être dociles ou soumises, elles mettent à distance les jugements scolaires portés sur elles et ce, de deux manières au moins : par l’adhésion forte au projet de formation en LP qui permet la valorisation d’autres manières de faire et d’apprendre à l’école ; par la mise à distance des enjeux scolaires et de formation, et par la valorisation d’un quant-à-soi adolescent.
Du collectif avec des femmes
Authors: Masó Joana 
Published: January 2023

L’asile de Saint-Alban-sur-Limagnole en Lozère est l’un des lieux où se sont développées, entre les années 1930 et 1960, des pratiques expérimentales psychiatriques à la fois politiques et artistiques, en particulier sous la direction du psychiatre catalan exilé François Tosquelles. Dans cette histoire devenue mythique, la présence des grands hommes a souvent occulté, d’une part, l’hôpital comme lieu de vie et de soins collectif et, d’autre part, le travail des femmes qui en dessinent les contours nouveaux. Cet article suit les traces de femmes dont le rôle a été passé sous silence dans la transmission de la psychothérapie institutionnelle et la « géo-psychiatrie » : des psychiatres, telles Agnès Masson et Germaine Balvet, ainsi que des travailleuses du sexe et des religieuses qui sont alors pleinement reconnues comme soignantes. Tosquelles a ainsi pu s’appuyer, non seulement sur son expérience de psychiatre pendant la guerre civile espagnole, mais aussi sur les pratiques institutionnelles et thérapeutiques de ces femmes. Il s’agit donc d’exhumer un pan d’histoire refoulé de la psychiatrie à la lumière de leur manière d’incarner un soin politique.
L’égalité au risque de la différence : la complication démocratique
Authors: Vibert Stéphane 
Published: January 2023

Les sociétés modernes pluralistes doivent nécessairement affronter, d’une façon ou d’une autre, le « paradoxe de l’identité démocratique » : la reconnaissance du pluralisme culturel et de la diversité communautaire, réinterprétés comme revendication subjective à l’authenticité, entre en potentielle contradiction avec l’affirmation de l’égalité des individus, assurée par la loi à partir d’une secondarisation des traits particuliers propres à chaque personne. Le slogan de « l’égalité dans la différence » lancé afin de répondre à ce défi théorique et politique ne peut masquer la difficulté de penser la nature du « monde commun » accueillant des mobilisations identitaires potentiellement contradictoires et antagonistes : d’une part, toute identité collective se prête à une essentialisation réductrice ; d’autre part, certaines minorités illibérales instrumentalisent les droits subjectifs afin d’en restreindre la nature émancipatoire. C’est essentiellement pour mieux penser cet écueil théorique que l’anthropologue Louis Dumont a insisté sur la nécessité, contextualisée et négociée, de hiérarchiser les revendications d’égalité et de différence au sein des sociétés démocratiques, notamment en soulignant la claire distinction entre ces deux types de reconnaissance distincts, malgré la confusion consistant à les assimiler sous un même registre de droits et de justice.
L’alignement de l’église orthodoxe russe sur le bellicisme du Kremlin
Authors: Philippenko Grégoire 
Published: January 2023

Depuis la fin de l’URSS, la doctrine de la guerre de l’Église orthodoxe russe a connu une évolution belliciste, pour culminer par un soutien à l’invasion de l’Ukraine du patriarche Kirill. Ceci est le résultat d’un alignement de la doctrine de l’Église sur celle de l’État. En effet, malgré la formalisation d’une doctrine de la « guerre juste » par l’Église en 2000, de nombreux symboles et discours ont contribué à une réinterprétation belliciste de cette doctrine. Cela est dû à l’influence du courant conservateur au sein de l’Église, qui bénéficie de liens privilégiés avec l’État. Ainsi, les positions officielles de l’Église ont justifié les guerres menées par la Russie depuis 2008, à travers l’exaltation de l’engagement militaire, et la sacralisation de la défense de la patrie.

Authors: Thomas Akshay S. , Thomas Mridul K. , Davis Emily C. , Fowler Samuel , Schneider Eric W. , Recchia Franco M. , Awh Carl C. 
Published: January 2023

Objective:
To compare peel-induced maculopathy (PIM) using surgical forceps versus the microvacuum pick (MVP).

Methods:
Consecutive eyes undergoing internal limiting membrane (ILM) peeling using either the MVP or forceps were assessed. En face optical coherence tomography (OCT) images at the level of the nerve fiber layer were generated for 6-month postoperative visit. The percentage of the imaged area showing PIM was termed the PIM index. PIM severity was additionally measured using a qualitative PIM severity scale.

Results:

Seventy-four consecutive eyes underwent ILM peeling with either the MVP (36/74; 49%) or forceps (38/74; 51%). At month-6 postoperatively, the mean PIM index for forceps was 7.7% vs 4.7% for the MVP (
P
< 0.001, R
2
= 0.15). At 6 months, 26/38 eyes (68.5%) in the forceps group had either moderate or severe PIM compared to 12/36 eyes (33.3%) in the MVP group (
P
= 0.001).

Conclusions:
ILM peeling with the MVP resulted in lower PIM severity compared to forceps.

Published: January 2023

Online teaching has become a decisive factor to keep growing in higher education settings. The present analytical correlational study examined the predictable factors that would help EFL Jordanian students engage in online learning in English courses after COVID-19 pandemic. To achieve the objective of the study, a validated and a reliable survey was administered to investigate the students’ perceptions toward various factors that would affect their success and engagement in online EFL classroom. Additionally, the relationship among some factors was investigated. Fifty-nine EFL students in an English Language Skills course in a technical university college in Jordan were randomly selected to respond to a questionnaire which was adapted from Bernard [7]. Data of the study were analyzed using the descriptive statistics (means and standard deviations) and Person Correlation Coefficient. Findings of the study confirmed that relationship among some factors has uncovered the importance of having basic skills in building other skills. A positive relationship was also found between the factors that help students engage in online learning and self- management. Findings of the study would be helpful for teachers, instructors, and course designers when designing and delivering online courses as well as policy makers
Pour en finir avec l'ordre symbolique. A propos de l'ouvrage: Ni d'Eve ni d'Adam. Défaire la différence des sexes
Authors: Bertini Marie-Joseph 
Published: January 2023

A quoi sert la différence des sexes ? L'ouvrage, à la croisée de la philosophie, de l'anthropologie et de la sociologie, montre que le système de la différence des sexes ne sert qu'à étayer celui de l'inégalité des sexes à travers le dispositif puissant de l'ordre symbolique, véritable théologie pratique que l'anthropologie structurale, la psychanalyse lacanienne et une certaine philosophie du Droit se font fort de relayer dans tous les domaines de nos sociétés. L'auteur mobilise une analyse critique des dispositifs stratégiques mettant en œuvre les principes qui animent nos valeurs, nos représentations et nos comportements. C’est au sacré que font étrangement appel les auteurs et les politiques qui nous défendent d’approcher de trop près cet ordre fondateur et transcendant, source originaire de notre humanité. Or cet ordre symbolique, processus d'assujettissement à un système de relations sociales hiérarchisées et figées, n'est rien d'autre que notre société elle-même en tant qu'elle s'épuise à se donner un fondement. De sorte que le système de l'ordre symbolique et de la hiérarchie des sexes nous renseignent moins sur ce qu'est une société humaine que sur ce qu'elle devrait être, manifestant ainsi que toute définition est clôture sur ses propres présupposés idéologiques de transcendance, de vérité et de morale.
Femmes et genre dans l’histoire de l’immigration. Naissance et cheminement d’un sujet de recherche
Authors: Guerry Linda 
Published: January 2023

Attentif au contexte et aux évolutions théoriques dans les sciences humaines et sociales, cet article présente l’historiographie d’un sujet de recherche encore peu abordé en France : les femmes et le genre dans l’histoire de l’immigration. L’article analyse les facteurs d’émergence et les premières approches d’un sujet qui a d’abord été travaillé par les sciences sociales et la difficile rencontre de l’histoire de l’immigration et de l’histoire des femmes (tant en France qu’aux États-Unis). Il présente enfin les recherches les plus récentes qui intègrent le genre à l’analyse historique du phénomène migratoire.
Savoirs mondains, savoirs savants : les femmes et leurs cabinets de curiosités au siècle des Lumières
Authors: Gargam Adeline 
Published: January 2023

Dans la France des Lumières, la culture de la curiosité est un phénomène de mode mais surtout un jeu social et intellectuel. La présente étude entend retracer l’histoire d’une trentaine de cabinets féminins de curiosité tenus à cette époque. Des femmes fortunées de l’aristocratie et de la bourgeoisie parisienne et provinciale ont alors constitué sous l’emprise de leur libido sciendi des cabinets d’alchimie, de minéralogie, de physique‑chimie, d’histoire naturelle et d’anatomie naturelle et artificielle. Ces cabinets obéissent à une typologie particulière. Il en existe deux catégories : les cabinets d’amateurs, constitués pour la parade et le spectacle des visiteurs et fonctionnant comme de véritables écoles de plaisirs intellectuels et éducatifs ; les cabinets à finalité scientifique et didactique, formés par des savantes expérimentées qui se livrent dans leurs laboratoires à des recherches personnelles et expérimentales au nom des progrès de la science médicale et de l’instruction publique. La réflexion porte aussi sur le fonctionnement de ces cabinets privés de curiosité, particulièrement sur leur mode de constitution, leur décor intérieur ainsi que sur le contenu des collections qui nécessitaient certaines techniques d’organisation, d’acquisition et de conservation communes à celles de leurs homologues masculins.
Application of Diode Laser in Excision of a Peripheral Ameloblastoma - A Case Report
Authors: Pakhira Soubhik , Raha Anirban , Mazumder Paramita 
Published: January 2023

Rationale:
Occurrence of peripheral ameloblastoma (PA) is rare. Excision of PA by diode laser is infrequent.

Patient Concerns:
A 27-year-old female patient presented with an asymptomatic mass on the retromolar trigone for the past one year.

Diagnosis:
Incisional biopsy showed aggressive PA.

Treatment:
The lesion was excised using a diode laser under local anaesthesia. The excised specimen revealed histopathological features of the acanthomatous variant of PA.

Outcomes:
The patient was followed up for two years without any evidence of recurrence.

Take-Away Lessons:
Diode laser is an acceptable alternative to conventional scalpel excision for intraoral soft tissue lesions, whereas, in the case of PA, it proves to be no exception.
Identification of Novel Cytochrome C1 (CYC1) Gene Expression in Oral Squamous Cell Carcinoma- An Evaluative Study
Authors: Ramasubramanian Abilasha , Arumugam Paramasivam , Ramani Pratibha , Kannan Bala Chander , Murugan M. Senthil 
Published: January 2023

Introduction:
Cytochrome C1 (CYC1) is an important subunit of mitochondrial complex III and plays a vital role in oxidative phosphorylation (OXPHOS) and reactive oxygen species generation. Overexpression of the CYC1 gene has been implicated in cancer development and its prognosis previously, but unexplored in head-and-neck squamous cell carcinomas (HNSCC), especially oral squamous cell carcinoma (OSCC).

Materials and Methods:
CYC1 m-RNA expression and gene alterations were assessed using the Cancer Genome Atlas dataset in HNSCC and validated in OSCC tissues using real-time polymerase chain reaction (RT-PCR). The protein–protein interaction (PPI) network and functional enrichment pathways were also analysed.

Results:
A thorough analysis of the TCGA (The Cancer Genome Atlas) database revealed that CYC1 was overexpressed in the HNSCC cases and the increased expression correlated with several parameters which involve the prediction of advanced diseases such as histopathological grade, tumour-node-metastasis staging, and nodal metastases (P < 0.05). The expression of CYC1 was validated using RT-PCR showing significant upregulation (P < 0.05) in OSCC tissue samples compared to the normal tissue counterparts. PPI network and functional analysis show the prominent role of CYC1 in OXPHOS, especially in electron transport chain III complex regulation.

Discussion:
The study revealed that CYC1 is highly expressed in HNSCC, and is validated in the OSCC patient tissue samples compared to the normal counterparts and associated with advanced disease stages and grade of the tumour. CYC1 could be a novel promising therapeutic and prognostic marker in HNSCC, especially in OSCC.
Dyadic Congruence, Dyadic Coping, and Psychopathology: Implications in Dyads for Patients with Acute Coronary Syndrome
Authors: Mitra Romita , Pujam S. Nandha Kumara , Jayachandra Amarapalli , Sharma Prafull 
Published: January 2023

Introduction:
Along with a worldwide growth of individuals diagnosed with coronary heart disease (CHD), the number of adults affected with acute coronary syndrome (ACS) has substantially increased over a period of time. Such negative effects are not only limited to the patient but also extend to the caregiver. With this growing importance of caregiving among dyads, there comes a commensurate need to carefully exploring the impact of the relationship on the mental and possible overall health of both. The aim of this study is to examine the impact of dyadic coping as a mediator in the relationship between dyadic congruence and psychopathology of patient-caregiver dyads with acute coronary syndrome.

Materials and Method:
The present study was of a cross-sectional design. A total of 216 dyads (108 patients and 108 caregivers) were selected for this study. All the participants were chosen from Base Hospital and SGT Hospital, India. Data was collected through survey which included measures to test dyadic congruence, dyadic coping, depression, anxiety and somatic symptoms.

Results:
Correlation and mediation analysis was carried out for statistical analysis. Dyadic coping significantly mediated the relationship between dyadic congruence and psychopathology among patients with acute coronary syndrome and their caregivers.

Conclusion:
The findings of the present study throw a light on the impact of dyadic congruence and dyadic coping on the mental health of both patients with acute coronary syndrome and their caregivers.
Dosimetric Effects of the Supine and Prone Positions in Proton Therapy for Prostate Cancer
Authors: Kato Takahiro , Kato Masato , Takemasa Kimihiro , Murakami Masao 
Published: January 2023

Purpose:
To quantitatively evaluate how much the doses to organs at risk are affected in the prone position compared to the supine position in the proton therapy (PT) for prostate cancer.

Materials and Methods:
Fifteen consecutive patients with clinically localized prostate cancer underwent treatment planning computed tomography scans in both the supine and prone positions. The clinical target volume (CTV) consisted of the prostate gland plus the seminal vesicles. The PT plans were designed using the standard lateral opposed fields with passively scattered proton beams for both treatment positions. The prescribed dose for each plan was set to 78 Gy (Relative biological effectiveness)/39 fractions to 50% of the planning target volume. Dose-volume metrics of the rectum and bladder in the two treatment positions were analyzed.

Results:
It was confirmed that all the parameters of D05, D10, D20, D30, Dmean, and V90 examined in the rectum were significantly reduced in the prone position. There was no significant difference between the two positions in the bladder dose except for Dmean. The distance between the CTV and the rectum tended to increase with the patient in the prone position; at the prostate level, however, the maximum change was approximately 5 mm, and there was significant variation between cases.

Conclusions:
We confirmed that the rectal doses were significantly lower in the prone compared with the supine position in PT. Although uncertain, the prone position could be an effective method to reduce the rectal dose in PT.

where
$f^{(n-k,k)}$
is the number of standard tableaux of shape
$(n-k,k)$
