White dwarf mass growth in cataclysmic variables: roles of dwarf novae
Authors: Liu Wei-Min , Jiang Long , Chen Wen-Cong , Li Xiang-Dong 
Published: May 2023

ABSTRACT
The disc instability mechanism (DIM) is widely accepted to account for the transient behaviour of dwarf novae (DNe), which experience short outbursts separated by long quiescence. The duty cycle (the ratio between the outburst duration and the recurrence time) determines the amount of accreted mass by the white dwarf (WDs) during outbursts, thus playing an important role in the long-term binary evolution. Employing the code of Modules for Experiments in Stellar Astrophysics, we systemically investigate the influence of the duty cycles on the evolution of DNe and the mass growth of accreting carbon-oxygen (CO) WDs. Our calculations show that, while the DIM can considerably influence the accretion process, efficient WD-mass growth requires a particular range of the duty cycle. For WDs with the initial masses of 0.6, 0.7, and 1.1 M⊙, these duty cycles are 0.006$\, \le$d$\, \le$0.007, d  =  0.005, and, d  = 0.003 and the accumulated mass of the WDs can reach 0.1, 0.13, and 0.21 M⊙, respectively. In all of our simulations, no CO WDs can grow their masses to the explosion mass of Type Ia supernovae of about 1.38 M⊙. Because of a much short time-scale of the outburst state, the final donor-star masses and orbital periods are insensitive to the duty cycles. Therefore, we propose that the DIM in DNe could alleviate the WD mass problem to some extent.

ABSTRACT
Jets of energetic particles, as seen in FR type-I and FR type-II sources, ejected from the centre of radio-loud AGN affect the sources surrounding the intracluster medium/intergalactic medium. Placing constraints on the age of such sources is important in order to measure the jet powers and determine the effects on feedback. To evaluate the age of these sources using spectral age models, we require high-resolution multiwavelength data. The new sensitive and high-resolution MIGHTEE survey of the XMM-LSS field, along with data from the Low Frequency Array (LOFAR) and the Giant Metrewave Radio Telescope (GMRT) provide data taken at different frequencies with similar resolution, which enables us to determine the spectral age distribution for radio-loud AGN in the survey field. In this study, we present a sample of 28 radio galaxies with their best-fitting spectral age distribution analysed using the Jaffe–Perola (JP) model on a pixel-by-pixel basis. Fits are generally good, and objects in our sample show maximum ages within the range of 2.8 to 115 Myr with a median of 8.71 Myr. High-resolution maps over a range of frequencies are required to observe detailed age distributions for small sources, and high-sensitivity maps will be needed in order to observe fainter extended emission. We do not observe any correlation between the total physical size of the sources and their age, and we speculate that both dynamical models and the approach to spectral age analysis may need some modification to account for our observations.

ABSTRACT
We present optical and near-infrared (NIR) observations of the Type Icn supernova (SN Icn) 2022ann, the fifth member of its newly identified class of SNe. Its early optical spectra are dominated by narrow carbon and oxygen P-Cygni features with absorption velocities of ∼800 km s−1; slower than other SNe Icn and indicative of interaction with a dense, H/He-poor circumstellar medium (CSM) that is outflowing slower than typical Wolf–Rayet wind velocities of &gt;1000 km s−1. We identify helium in NIR spectra 2 weeks after maximum and in optical spectra at 3 weeks, demonstrating that the CSM is not fully devoid of helium. Unlike other SNe Icn, the spectra of SN 2022ann never develop broad features from SN ejecta, including in the nebular phase. Compared to other SNe Icn, SN 2022ann has a low luminosity (o-band absolute magnitude of ∼−17.7), and evolves slowly. The bolometric light curve is well-modelled by 4.8 M⊙ of SN ejecta interacting with 1.3 M⊙ of CSM. We place an upper limit of 0.04 M⊙ of 56Ni synthesized in the explosion. The host galaxy is a dwarf galaxy with a stellar mass of 107.34 M⊙ (implied metallicity of log(Z/Z⊙) ≈ 0.10) and integrated star-formation rate of log (SFR) = −2.20 M⊙ yr−1; both lower than 97 per cent of galaxies observed to produce core-collapse supernovae, although consistent with star-forming galaxies on the galaxy Main Sequence. The low CSM velocity, nickel and ejecta masses, and likely low-metallicity environment disfavour a single Wolf–Rayet progenitor star. Instead, a binary companion is likely required to adequately strip the progenitor and produce a low-velocity outflow.
Les considérations en matière de confidentialité et de protection de la vie privée lors de la prestation des services de santé aux adolescents
Authors: Agostino Holly , Toulany Alene 
Published: May 2023

Résumé
La confidentialité des soins fait partie des caractéristiques des services de santé de qualité aux adolescents. Du temps seul à seul avec le professionnel de la santé, l’accès à l’information en matière de santé réservé aux personnes autorisées et l’obtention d’un consentement éclairé avant de donner les services sans demander le consentement d’un parent, d’un tuteur ou d’un proche, font partie des fondements des soins confidentiels aux adolescents. La confidentialité est un principe fondamental qui s’applique à toutes les rencontres médicales, quel que soit l’âge, mais les considérations propres aux patients adolescents aptes ne sont pas toujours comprises ni prises en compte. S’ils donnent aux adolescents des soins confidentiels d’une quantité et d’une qualité appropriées, les cliniciens sont mieux en mesure d’obtenir une anamnèse et un examen physique complets, et ils habilitent les adolescents à développer leur capacité d’agir, leur autonomie, leur confiance et leur responsabilité à l’égard de leurs décisions en matière de santé et de la prise en charge de leurs propres soins.
Le temps d’écran et les enfants d’âge préscolaire : la promotion de la santé et du développement dans un monde numérique
Authors: Ponti Michelle 
Published: May 2023

Résumé
La COVID-19 a transformé l’environnement médiatique familial et suscité des recherches sur les effets de l’exposition aux médias sur écran et de leur utilisation chez les jeunes enfants. La présente mise à jour d’un document de principes de la SCP publié en 2017 passe de nouveau en revue les bienfaits et les risques potentiels des médias sur écran chez les enfants de moins de cinq ans et s’attarde sur leur santé développementale, psychosociale et physique. Quatre principes reposant sur des données probantes — limiter le temps d’écran, en atténuer les effets négatifs, les utiliser en pleine conscience et donner l’exemple d’habitudes saines — continuent d’orienter l’expérience précoce des enfants dans un paysage médiatique en rapide évolution. Les connaissances sur l’apprentissage et le développement des jeunes enfants éclairent les pratiques exemplaires recommandées aux professionnels de la santé et aux professionnels de la petite enfance (p. ex., éducatrices à la petite enfance, fournisseurs de services de garde). Les conseils préventifs devraient désormais inclure l’utilisation des écrans par les enfants et les familles en contexte de pandémie (et par la suite).
Is the neighborhood of interaction in human crowds metric, topological, or visual?
Authors: Wirth Trenton D , Dachner Gregory C , Rio Kevin W , Warren William H 
Published: May 2023

Abstract
Global patterns of collective motion in bird flocks, fish schools, and human crowds are thought to emerge from local interactions within a neighborhood of interaction, the zone in which an individual is influenced by their neighbors. Both metric and topological neighborhoods have been reported in animal groups, but this question has not been addressed for human crowds. The answer has important implications for modeling crowd behavior and predicting crowd disasters such as jams, crushes, and stampedes. In a metric neighborhood, an individual is influenced by all neighbors within a fixed radius, whereas in a topological neighborhood, an individual is influenced by a fixed number of nearest neighbors, regardless of their physical distance. A recently proposed alternative is a visual neighborhood, in which an individual is influenced by the optical motions of all visible neighbors. We test these hypotheses experimentally by asking participants to walk in real and virtual crowds and manipulating the crowd's density. Our results rule out a topological neighborhood, are approximated by a metric neighborhood, but are best explained by a visual neighborhood that has elements of both. We conclude that the neighborhood of interaction in human crowds follows naturally from the laws of optics and suggest that previously observed “topological” and “metric” interactions might be a consequence of the visual neighborhood.
The genomic diversity of Taiwanese Austronesian groups: Implications for the “Into- and Out-of-Taiwan” models
Authors: Liu Dang , Ko Albert Min-Shan , Stoneking Mark 
Published: May 2023

Abstract
The origin and dispersal of the Austronesian language family, one of the largest and most widespread in the world, have long attracted the attention of linguists, archaeologists, and geneticists. Even though there is a growing consensus that Taiwan is the source of the spread of Austronesian languages, little is known about the migration patterns of the early Austronesians who settled in and left Taiwan, i.e. the “Into-Taiwan” and “out-of-Taiwan” events. In particular, the genetic diversity and structure within Taiwan and how this relates to the into-/out-of-Taiwan events are largely unexplored, primarily because most genomic studies have largely utilized data from just two of the 16 recognized Highland Austronesian groups in Taiwan. In this study, we generated the largest genome-wide data set of Taiwanese Austronesians to date, including six Highland groups and one Lowland group from across the island and two Taiwanese Han groups. We identified fine-scale genomic structure in Taiwan, inferred the ancestry profile of the ancestors of Austronesians, and found that the southern Taiwanese Austronesians show excess genetic affinities with the Austronesians outside of Taiwan. Our findings thus shed new light on the Into- and Out-of-Taiwan dispersals.
Staying True to the Founding Principles: A Review Article
Authors: Bessette Joseph M 
Published: May 2023

Abstract
In The Nation That Never Was: Reconstructing America's Story, Kermit Roosevelt III argues that Americans fundamentally misunderstand the nation's founding principles, especially as articulated in the Declaration of Independence of 1776. We think that the Declaration stood for human equality and freedom – “a set of aspirations toward which the best in American history strive.” Roosevelt insists that this “view of the Declaration is exactly what we must let go.” Properly understood, the Declaration “is consistent with slavery” and even condones it: “A government that protects the rights of its citizens, including their right to enslave outsiders, is a Declaration-style government.” Roosevelt's view, however, is bereft of support in the historical record. No author of the Declaration argued that it condoned slavery. Within three decades of the nation's founding, half the states abolished slavery largely by appealing to the principles of the Declaration. Similarly, the abolitionists of the 1830s and Abraham Lincoln in the 1850s explicitly appealed to the anti-slavery principles of the Declaration. Roosevelt's own heroes of Reconstruction – leaders like John Bingham, Thaddeus Stevens, and Charles Sumner – all embraced an understanding of the Declaration fundamentally at odds with his own. Finally, Martin Luther King, whom Roosevelt claims gave lip service to the “standard story” of the American Founding only for tactical reasons and who “set aside the Founding entirely” by “the end of his life,” actually praised the Founding Fathers, the Declaration of Independence, and the Constitution” the very day before his assassination in April of 1968.
Legacies of Resistance and Resilience: Antebellum Free African Americans and Contemporary Minority Social Control in the Northeast
Authors: Ward Matthew 
Published: May 2023

Abstract
To understand the persistence of racial disparities in the United States, inequality scholars have increasingly focused attention on historic regimes of violence and social control. In particular, a burgeoning literature examines the legacy of slavery, generally finding that where slavery was deeply entrenched, today racial inequalities and African-American deprivation are more acute. However, taking seriously the notion that history matters means considering not only the lingering effects of dehumanizing social control institutions like slavery but also the ramifications of antebellum institutions and cultures of resistance and resilience African Americans built for survival. Using quantitative methods, I examine the relationship between antebellum free African-American populations and racial inequalities in modern state-sanctioned social control. Focusing on the understudied Northeast, a region where free African-American communities flourished despite coexisting with slavery, I find that where free African Americans were more prevalent—and, thus, resistance to White’s social control efforts and resilience in the face of White hostility more robust—those same areas today display reduced levels of racial inequality in social control (i.e., lower Black–White arrest rate disparities) and reduced absolute levels of minority social control (i.e., lower African-American arrest rates). Mediation analyses reveal contemporary civil rights infrastructure, Black congregations, and Black political power operate as structural safeguards and are important components of the legacies of resistance and resilience left by free African Americans.
TFAP2C inhibits cell autophagy to alleviate myocardial ischemia/reperfusion injury by regulating miR‐23a‐5p/SFRP5/Wnt5a axis

Published: May 2023

AbstractMyocardial ischemia/reperfusion (MI/R) injury contributes to severe injury for cardiomyocytes. In this study, we aimed to explore the underlying mechanism of TFAP2C on cell autophagy in MI/R injury. MTT assay measured cell viability. The cells injury was evaluated by commercial kits. IF detected the level of LC3B. Dual luciferase reporter gene assay, ChIP or RIP assay were performed to verify the interactions between crucial molecules. We found that TFAP2C and SFRP5 expression were decreased while miR‐23a‐5p and Wnt5a increased in AC16 cells in response to H/R condition. H/R induction led to cell injury and induced autophagy, which were reversed by TFAP2C overexpression or 3‐MA treatment (an autophagy inhibitor). Mechanistically, TFAP2C suppressed miR‐23a expression through binding to miR‐23a promoter, and SFRP5 was a target gene of miR‐23a‐5p. Moreover, miR‐23a‐5p overexpression or rapamycin reversed the protective impacts of TFAP2C overexpression on cells injury and autophagy upon H/R condition. In conclusion, TFAP2C inhibited autophagy to improve H/R‐induced cells injury by mediating miR‐23a‐5p/SFRP5/Wnt5a axis.

Authors: Santacruz Carlos A. , Vincent Jean-Louis , Duitama Jorge , Bautista Edwin , Imbault Virginie , Bruneau Michael , Creteur Jacques , Brimioulle Serge , Communi David , Taccone Fabio S. 
Published: May 2023

Background:
Danger-associated molecular patterns (DAMPs) may be implicated in the pathophysiological pathways associated with an unfavorable outcome after acute brain injury (ABI).

Methods:
We collected samples of ventricular cerebrospinal fluid (vCSF) for 5 days in 50 consecutive patients at risk of intracranial hypertension after traumatic and nontraumatic ABI. Differences in vCSF protein expression over time were evaluated using linear models and selected for functional network analysis using the PANTHER and STRING databases. The primary exposure of interest was the type of brain injury (traumatic vs. nontraumatic), and the primary outcome was the vCSF expression of DAMPs. Secondary exposures of interest included the occurrence of intracranial pressure ≥20 or ≥ 30 mm Hg during the 5 days post-ABI, intensive care unit (ICU) mortality, and neurological outcome (assessed using the Glasgow Outcome Score) at 3 months post-ICU discharge. Secondary outcomes included associations of these exposures with the vCSF expression of DAMPs.

Results:
A network of 6 DAMPs (DAMP_

trauma
; protein-protein interaction [PPI] P=0.04) was differentially expressed in patients with ABI of traumatic origin compared with those with nontraumatic ABI. ABI patients with intracranial pressure ≥30 mm Hg differentially expressed a set of 38 DAMPS (DAMP_

ICP30
; PPI P< 0.001). Proteins in DAMP_

ICP30
are involved in cellular proteolysis, complement pathway activation, and post-translational modifications. There were no relationships between DAMP expression and ICU mortality or unfavorable versus favorable outcomes.

Conclusions:
Specific patterns of vCSF DAMP expression differentiated between traumatic and nontraumatic types of ABI and were associated with increased episodes of severe intracranial hypertension.
Methicillin-Resistant Staphylococcus aureus Pneumatoceles in a Neonate With Sotos Syndrome
Authors: Perdue Samantha , Newberry Desi 
Published: May 2023

Background:
Necrotizing pneumonia caused by methicillin-resistant Staphylococcus aureus can lead to the formation of pneumatoceles in the lungs. Standard treatment guidelines are not available due to the rarity of pneumatoceles in neonates.

Clinical Findings:
Baby H. required prolonged respiratory support and supplemental oxygen to maintain appropriate oxygen saturation parameters for infants more than 34 weeks' gestation corrected. He was found to have multiple pneumatoceles in both lungs on different radiological modalities.

Primary Diagnosis:
Baby H. was a former 32.2-week gestation male infant diagnosed with pneumonia caused by necrotizing methicillin-resistant Staphylococcus aureus leading to pneumatocele formation in both lungs.

Interventions:
Baby H. was managed with aggressive antibiotic therapy and then was conservatively managed until he received a tracheostomy tube on day of life (DOL) 75 to prepare for discharge home.

Outcomes:
Baby H. was discharged from the neonatal intensive care unit (NICU) on DOL 113 with a tracheostomy tube for prolonged mechanical ventilatory support and a gastrostomy tube for nutrition. Numerous follow-up appointments with specialists have occurred since discharge.

Practice Recommendations:
While methicillin-resistant Staphylococcus aureus pneumatoceles are uncommon in the NICU setting, it is important for neonatal care providers to be aware of the causes and treatment choices currently available. Although conservative therapy is commonly utilized, it is important that nurses learn other available management strategies such as the ones highlighted in this article to best advocate for their patients.
Chronic Atypical Neutrophilic Dermatosis With Lipodystrophy and Elevated Temperature Syndrome: A Systemic Review
Authors: Altom Ahmad , Khader Sarah Abd Elaziz , Gad Abdelrahman Gamil , Anadani Rami , Dang Dung Phuong , Ansar Farrukh , Chaudhari Jinalben , Crespo-Quezada Juan , Huy Nguyen Tien 
Published: May 2023

Background:
Chronic atypical neutrophilic dermatosis with lipodystrophy and elevated temperature syndrome is a rare, hereditary, autoinflammatory disease. However, there are few cases reported in the literature. Therefore, we conduct this systematic review to summarize current evidence.

Methods:
We conducted a systematic search in July 2021 using 11 different electronic databases. The included articles were screened according to our inclusion and exclusion criteria and assessed using an appropriate quality assessment tool. Then, the relevant data were extracted and summarized in tables accordingly. Each step of the previous one was done by 3 independent reviewers, and the conflicts were resolved by discussion and sometimes by counseling a senior member.

Results:
The final included studies were 18 articles with 34 cases (mean age = 8 years, male/female = 19/15). The most reported symptoms and signs were fever 97.1%, erythematous plaques 76.5%, arthralgia 67.6%, hepatomegaly 61.8%, violaceous hue 61.8%, lipodystrophy in extremities 53.1% in addition to low weight and height. Rare features were reported too. The laboratories were not specific, which may be explained by a systemic inflammatory response. Vasculitis was the dominant feature in the skin biopsy, whereas the calcification in the basal ganglia was a prominent sign in many cases.

Conclusions:
Fever, skin lesions, and systemic inflammatory response were the prominent features of chronic atypical neutrophilic dermatosis with lipodystrophy and elevated temperature syndrome. The clinical picture is the main guide in addition to the pathological findings. Mutation detection is the confirmatory test. Prednisolone is the most effective reported treatment for acute presentations in the literature.
Leser-Trélat Sign in Association With Diffuse Large B-Cell Lymphoma: A Case Report
Authors: Li Wei , Zhang Ming , Xu Tao , Huang Jian-Guo , Fan Jian-Yong 
Published: May 2023

Introduction:
The Leser-Trélat sign is a paraneoplastic skin syndrome characterized by the sudden eruption of pruritic seborrheic keratoses in association with underlying carcinoma.
Herein, we report a rare case of the Leser-Trélat sign in association with B-cell lymphoma.

Case presentation:
A 76-year-old man presented at our hospital with lower back/abdominal pain and a sudden eruption of black papules at multiple sites. Contrast-enhanced CT indicated a solid abdominal mass with multiple metastases. The histopathological examination of a lymph node biopsy led to a diagnosis of diffuse large B-cell lymphoma. A biopsy of the black papules confirmed the diagnosis of seborrheic keratoses.

Discussion:
The clinical and histological findings supported the diagnosis of the Leser-Trélat sign. The seborrheic keratoses were skin manifestations of diffuse large B-cell lymphoma.

Conclusion:
Clinicians should be aware that the eruption of seborrheic keratoses may be associated with visceral malignancy. To the best of our knowledge, this is the first case report of the Leser-Trélat sign in association with diffuse large B-cell lymphoma.
