Abstract
Accretion plays a central role in the physics that governs the evolution and dispersal of protoplanetary disks. The primary goal of this paper is to analyze the stability over time of the mass accretion rate onto TW Hya, the nearest accreting solar-mass young star. We measure veiling across the optical spectrum in 1169 archival high-resolution spectra of TW Hya, obtained from 1998–2022. The veiling is then converted to accretion rate using 26 flux-calibrated spectra that cover the Balmer jump. The accretion rate measured from the excess continuum has an average of 2.51 × 10−9
M
⊙ yr−1 and a Gaussian distribution with an FWHM of 0.22 dex. This accretion rate may be underestimated by a factor of up to 1.5 because of uncertainty in the bolometric correction and another factor of 1.7 because of excluding the fraction of accretion energy that escapes in lines, especially Lyα. The accretion luminosities are well correlated with He line luminosities but poorly correlated with Hα and Hβ luminosity. The accretion rate is always flickering over hours but on longer timescales has been stable over 25 years. This level of variability is consistent with previous measurements for most, but not all, accreting young stars.

) satellite galaxies of M31 based on deep color–magnitude diagrams constructed from Hubble Space Telescope imaging. These are the first SFHs obtained from the oldest main-sequence turnoff of UFDs outside the halo of the Milky Way (MW). We find that five UFDs formed at least 50% of their stellar mass by z = 5 (12.6 Gyr ago), similar to known UFDs around the MW, but that 10%–40% of their stellar mass formed at later times. We uncover one remarkable UFD, And xiii, which formed only 10% of its stellar mass by z = 5, and 75% in a rapid burst at z ∼ 2–3, a result that is robust to choices of underlying stellar model and is consistent with its predominantly red horizontal branch. This “young” UFD is the first of its kind and indicates that not all UFDs are necessarily quenched by reionization, which is consistent with predictions from several cosmological simulations of faint dwarf galaxies. SFHs of the combined MW and M31 samples suggest reionization did not homogeneously quench UFDs. We find that the least-massive MW UFDs (M
*(z = 5) ≲ 5 × 104
M
⊙) are likely quenched by reionization, whereas more-massive M31 UFDs (M
*(z = 5) ≳ 105
M
⊙) may only have their star formation suppressed by reionization and quench at a later time. We discuss these findings in the context of the evolution and quenching of UFDs.
Collapse of Rotating Massive Stars Leading to Black Hole Formation and Energetic Supernovae
Authors: Fujibayashi Sho , Sekiguchi Yuichiro , Shibata Masaru , Wanajo Shinya 
Published: October 2023

Abstract
We explore a possible explosion scenario resulting from core collapses of rotating massive stars that leave a black hole by performing radiation-viscous-hydrodynamics simulations in numerical relativity. We take moderately and rapidly rotating compact pre-collapse stellar models with zero-age main-sequence masses of 9M
⊙ and 20M
⊙ based on stellar evolution calculations as the initial conditions. We find that viscous heating in the disk formed around the central black hole is the power source for an outflow. The moderately rotating models predict a small ejecta mass of the order of 0.1M
⊙ and an explosion energy of ≲1051 erg. Due to the small ejecta mass, these models may predict a short-timescale transient with a rise time of 3–5 days. This can lead to a bright (∼1044 erg s−1) transient, like superluminous supernovae in the presence of a dense massive circumstellar medium. For hypothetically rapidly rotating models that have a high mass-infall rate onto the disk, the explosion energy is ≳3 × 1051 erg, which is comparable to or larger than that of typical stripped-envelope supernovae, indicating that a fraction of such supernovae may be explosions powered by black hole accretion disks. The explosion energy is still increasing at the end of the simulations with a rate of >1050 erg s−1, and thus, it may reach ∼1052 erg. A nucleosynthesis calculation shows that the mass of 56Ni amounts to ≳0.1M
⊙, which, together with the high explosion energy, may satisfy the required amount for broad-lined type Ic supernovae. Irrespective of the models, the lowest value of the electron fraction of the ejecta is ≳0.4; thus, synthesis of heavy r-process elements is not found in our models.
The Role of Mass and Environment on Satellite Distributions around Milky Way Analogs in the Romulus25 Simulation

Published: October 2023

Abstract
We study satellite counts and quenched fractions for satellites of Milky Way analogs in Romulus25, a large-volume cosmological hydrodynamic simulation. Depending on the definition of a Milky Way analog, we have between 66 and 97 Milky Way analogs in Romulus25, a 25 Mpc per-side uniform volume simulation. We use these analogs to quantify the effect of environment and host properties on satellite populations. We find that the number of satellites hosted by a Milky Way analog increases predominantly with host stellar mass, while environment, as measured by the distance to a Milky Way–mass or larger halo, may have a notable impact in high isolation. Similarly, we find that the satellite quenched fraction for our analogs also increases with host stellar mass, and potentially in higher-density environments. These results are robust for analogs within 3 Mpc of another Milky Way–mass or larger halo, the environmental parameter space where the bulk of our sample resides. We place these results in the context of observations through comparisons to the Exploration of Local VolumE Satellites and Satellites Around Galactic Analogs surveys. Our results are robust to changes in Milky Way analog selection criteria, including those that mimic observations. Finally, as our samples naturally include Milky Way–Andromeda pairs, we examine quenched fractions in pairs versus isolated systems. We find potential evidence, though not conclusive, that pairs, defined as being within 1 Mpc of another Milky Way–mass or larger halo, may have higher satellite quenched fractions.
Prediction of the Transit Time of Coronal Mass Ejections with an Ensemble Machine-learning Method

Published: October 2023

Abstract
Coronal mass ejections (CMEs), a kind of violent solar eruptive activity, can exert a significant impact on space weather. When arriving at the Earth, they interact with the geomagnetic field, which can boost the energy supply to the geomagnetic field and may further result in geomagnetic storms, thus having potentially catastrophic effects on human activities. Therefore, accurate forecasting of the transit time of CMEs from the Sun to the Earth is vital for mitigating the relevant losses brought by them. XGBoost, an ensemble model that has better performance in some other fields, is applied to the space weather forecast for the first time. During multiple tests with random data splits, the best mean absolute error (MAE) of ∼5.72 hr was obtained, and in this test, 62% of the test CMEs had absolute arrival time error of less than 5.72 hr. The average MAE over all random tests was ∼10 hr. It indicates that our method has a better predictive potential and baseline. Moreover, we introduce two effective feature importance ranking methods. One is the information gain method, a built-in method of ensemble models. The other is the permutation method. These two methods combine the learning process of the model and its performance to rank the CME features, respectively. Compared with the direct correlation analysis on the sample data set, they can help select the important features that closely match the model. These two methods can assist researchers to process large sample data sets, which often require feature selection in advance.
Réflexions sur les enveloppes psychiques, l’être sans secours et le Nebenmensch dans l’expérience traumatique de l’enfermement
Authors: Kaës René 
Published: October 2023

« Réflexions sur les enveloppes psychiques, l’être sans secours et le Nebenmensch dans l’expérience traumatique de l’enfermement. » Sensibilisé à ces questions par sa pratique professionnelle, l’auteur revient ici sur deux termes introduits par Freud : la Hilflosigkeit et le Nebenmensch . Attentif aux représentations, émotions et intentions émanant de situations d’enfermement traumatique, il mesure la pertinence de cette terminologie à propos du confinement lié au Covid-19, que ce soit à domicile, dans les services hospitaliers ou les EHPAD, mais aussi à propos des camps de rétention de migrants. Précisant la fonction du Nebenmensch , qu’il rapproche de celle de porte-parole de la mère auprès de l’ infans , il met en évidence un effet que l’on retrouve aussi bien chez ce dernier que chez le reclus, le migrant ou le malade victimes de maltraitance : l’accompagnement par la parole d’un proche secourable et son écoute permettent de dégager ceux-ci de leur détresse sans recours en revenant à la parole pour remailler les fils de leur histoire.
Toujours revenir à Alminhas
Authors: Chomy Lucien 
Published: October 2023

« Toujours revenir à Alminhas. » L’auteur voudrait illustrer un travail du néo-groupe lors d’une TFP : le passage des ressentis aux éprouvés et des éprouvés à la pensée réflexive. Cette transformation s’effectue dans la dynamique des mouvements transférentiels et contretransférentiels, grâce aux médiateurs dont le groupe s’emparent. Ce trajet mène à des formes de pensées capables, progressivement, de représenter les antécédents traumatiques familiaux qui empêchaient les éclosions individuelles jusqu’à l’apparition de la mythopoïèse. Des éléments cliniques saillants pour le travail se font jour à l’évocation des allers-retours de la famille entre la France, pays d’accueil, et le Portugal, pays d’origine.
Créations picturales de l’analyste en post-séance
Authors: Darchis Élisabeth 
Published: October 2023

« Créations picturales de l’analyste en post-séance. » Le dessin du thérapeute familial en post-séance soutient la rêverie du néo-groupe et favorise la construction d’une enveloppe psychique familiale. Ces créations picturales vont faire émerger des formes primitives, véritables signifiants formels, se rapportant aux souffrances du groupe et témoignant de non-dits, voire d’effets fantômes. Un exemple clinique nous aidera à comprendre comment cette polyphonie de la rêverie favorise la relance d’un processus dans la cure.

Published: October 2023

« Le cambriolage, effraction de l’enveloppe familiale. » Cette recherche propose une nouvelle approche d’évaluation du traumatisme à l’échelle familiale auprès de familles qui ont vécu un cambriolage. À l’aide d’un nouvel outil médiateur intitulé « la maison blessée » et de l’épreuve projective de la maison de rêve, les auteurs ont évalué les productions graphiques et le verbatim des familles. Leur objectif est de mettre en évidence les difficultés familiales liées au traumatisme, les angoisses inhérentes de telles attaques, les mécanismes de défenses et les capacités de résilience familiale.
Le signifiant formel : Origine et évolution d’un concept créateur
Authors: Lebon Cristelle 
Published: October 2023

« Le signifiant formel : origine et évolution d’un concept créateur. » L’auteur revient sur l’histoire du concept de signifiant formel : de ses précurseurs dans l’œuvre freudienne, aux inspirations puisées par D. Anzieu dans les travaux de ses contemporains, ce concept est porteur, dans son essence même, d’intersubjectivité. Repris dans la littérature psychanalytique depuis les années 2000, à la faveur des travaux en périnatalité et des recherches sur les formes de symbolisation primaire, le signifiant formel s’étend à la clinique des groupes et des familles dans des thèses et publications, dont les résultats sont présentés ici. L’article réinterroge ce concept, parfois difficile d’accès pour les cliniciens, afin d’éclairer la compréhension et la richesse clinique considérable des signifiants formels dans l’approche des formes de réactivation de traces d’expériences traumatiques en TFP.
Le texte caché du récit d’asile
Authors: Bouhamidi Lou 
Published: October 2023

En France, les personnes demandant l’asile sont soumises à la rédaction en français d’un récit des persécutions qu’elles ont subies dans leur pays d’origine. Le présent article entend explorer les enjeux sous-tendus par l’imposition d’une narration en français dans ce cadre. Pour ce faire, plusieurs mécanismes impliqués par la procédure sont dégagés, à partir de la notion de « texte caché » de J. Scott : les normes implicites qui régissent l’examen des demandes, les attentes institutionnelles en matière de narration en audience par lesquelles l’institution se fait co-productrice du récit, et la trajectoire symbolique du récit au cours de la procédure, qui publicise un texte caché d’origine. Au regard de ces implicites, l’article interroge le rôle que joue ce récit quant à un roman national qu’il corrobore et concurrence à la fois.
« C’est normal » : les fonctions des énoncés évaluatifs dans les entretiens entre les éducatrices de la petite enfance et les parents
Authors: Bimonte Ayla , Zogmal Marianne 
Published: October 2023

Cet article s’intéresse aux pratiques évaluatives et langagières accomplies lors d’entretiens de bilan dans le champ de l’éducation de l’enfance. Ces pratiques d’évaluation se trouvent convoquées dans une tension avec une injonction visant un travail en partenariat entre parents et professionnel.le.s. À partir de la démarche théorique et méthodologique de l’analyse interactionnelle, l’article étudie six extraits d’entretien dans lesquels l’énoncé évaluatif « c’est normal » apparait de façon récurrente. Ce phénomène énonciatif remplit différentes fonctions : celle de négocier les savoirs mis en circulation, d’établir les positionnements relationnels entre les participants, et de co-construire l’argumentation dans la structuration du discours en interaction. L’article discute de l’imbrication de ces fonctions ainsi que de l’importance des compétences d’interaction mobilisées par les professionnel.le.s afin de créer les conditions d’une relation partenariale avec les parents au moment des rencontres.
Récit de vie en santé mentale : enquête sur soi, en quête de soi
Authors: Jouet Emmanuelle 
Published: October 2023

Ce travail s’intéresse à des moments de construction de savoirs de « formateurs pairs » vivant avec des troubles psychiques, membres d’une communauté d’apprentissage où ils produisent leur récit de soi afin de pouvoir exercer dans des dispositifs de formation. La question est de voir en quoi une analyse lexicale peut aider à l’exploration de traces produites en éclairant les mécanismes à l’œuvre. Sont concernées (1) une analyse d’écritures à partir de la question « Qu’est-ce que vous avez appris de la maladie ? » ; (2) une analyse des verbatims produits par le groupe en vue de la réalisation d’un référentiel de compétences. Ce travail fait ressortir la complémentarité entre l’échange collectif, qui permet la thématisation et l’explication des savoirs, et l’écriture individuelle. Elle révèle des stratégies et des régimes narratifs différenciés, comme descriptifs, biographiques ou métaphoriques.
Evaluation and Approach to Patients with Psychodermatoses
Authors: Mehta Hitaishi , Narang Tarun 
Published: October 2023

Abstract
Psychodermatology is an emerging subspecialty of dermatology. It encompasses the management of patients with primary psychiatric disease presenting to dermatologists (e.g., delusional infestation, body dysmorphic disease, and factitious diseases), together with patients who have primary dermatological disease (e.g., psoriasis, atopic eczema, hair disorders, and others) with a psychiatric or psychological comorbidity. This review presents a practical approach to patients with psychocutaneous disease keeping in mind that the management requires the input of a wide multidisciplinary team including dermatologists, psychiatrists, psychologists, and primary care physicians, among others. The aim is to provide an overview on effectively building a therapeutic alliance with a psychodermatology patient in order to improve therapeutic outcomes. Dermatologists should be able to initiate basic pharmacotherapy, have a basic knowledge of nonpharmacological therapies, and be able to judge which patients need urgent psychiatric referral. Awareness of this group of disorders will enable a holistic management that takes care of body as well as the mind.
Serum Prolactin Level in Women with Systemic Lupus Erythematosus and its Correlation with Disease Activity
Authors: Mohammed Jinan Q. , Mathkhor Abdulsatar Jabar , Kamel Zahraa Mustafa 
Published: October 2023

Abstract

Background:
In the last decade, evidence supports the hypothesis that the prolactin (PRL) hormone plays an important role in systemic lupus erythematosus (SLE) clinical expression and pathogenesis.

Objective:
To evaluate the presence, clinical, and serological significance of elevated serum PRL in women with SLE.

Materials and Methods:
A case–control study included 30 women with SLE; with mean age and disease duration were 33.15 ± 6.7 and 10.9 ± 1.9, respectively, and 30 age-matched apparently healthy subjects served as controls. All patients were subjected to clinical and serological evaluation. Disease activity was measured using the SLE Disease Activity Index. Serum PRL level was estimated for all the participants.

Results:
Serum PRL levels were 36.2 ± 15.8 ng/ml and 8.9 ± 4.4 ng/ml in patients with SLE and controls, respectively. Malar rash, photosensitivity, and arthritis were associated with elevated serum PRL. Positive antinuclear antibodies ANA and low complements were associated with a high serum PRL level. In addition, 18 (85.7%) patients with high disease activity have hyperprolactinemia, while only 3 (14.3%) patients with high disease activity have a normal range of serum PRL levels.

Conclusion:
SLE patients were associated with higher serum PRL levels than the control group. There was a significant relationship between serological status and hypocomplementemia with high serum PRL levels. In addition, there was a significant relationship between active disease and hyperprolactinemia.
A Cross-Sectional Study to Determine the Prevalence of Thyroid Autoimmunity in Patients with Chronic Spontaneous Urticaria
Authors: Singh Pallavi , Sardesai Vidyadhar R 
Published: October 2023

Abstract

Background:
Chronic spontaneous urticaria (CSU) can be a distressing condition for both the patient and the treating doctor due to the lack of a definite underlying etiology. The condition has been found to be associated with autoimmune (AI) conditions, which brings to light possible pathogenesis being shared by AI conditions and chronic urticaria. This can help us understand the condition better as well as have a bearing on the treatment. Thyroid autoimmunity is one such condition which has commonly been associated with chronic urticaria.

Objectives:
To determine the prevalence of thyroid autoimmunity in patients with CSU. To determine the correlation between thyroid autoantibodies level and the severity and duration of CSU.

Materials and Methods:
Forty-eight adult patients of CSU were enrolled, in whom thyroid autoimmunity was determined by detecting the levels of anti-thyroid peroxidase (anti-TPO) antibody. Urticaria Activity Score was used to determine the activity of the disease.

Results:
Nine out of 48 (18.75%) patients showed raised anti-TPO antibody levels. Eight out of those 9 (88.89%) patients were female. No correlation was found between the duration of disease and the antibody levels. A significant association was found between the disease activity and anti-TPO antibody levels.

Conclusion:
The prevalence of thyroid autoimmunity is higher in patients of CSU compared to the general population. The condition occurs more frequently and with greater severity in the female population.
