Abstract
We present observations of an extreme radio flare, VT J024345.70-284040.08, hereafter VT J0243, from the nucleus of a galaxy with evidence for historic Seyfert activity at redshift z = 0.074. Between NRAO Very Large Array (VLA) Sky Survey observations in 1993 to VLA Sky Survey observations in 2018, VT J0243 rose from a ∼ GHz radio luminosity of ν

ν
∼ 1040 erg s−1, and still continues to brighten. The radio spectral energy distribution evolution is consistent with a nascent jet that has slowed over ∼3000 days with an average 0.1 <〈β〉< 0.6. The jet is energetic (∼1051–52 erg), and had a radius ∼0.7 pc in 2021 December. X-ray observations suggest a persistent or evolving corona, possibly associated with an accretion disk, and IR and optical observations constrain any high-energy counterpart to be sub-Eddington. VT J0243 may be an example of a young, off-axis radio jet from a slowly evolving tidal disruption event. Other more mysterious triggers for the accretion enhancement and jet launching are possible. In either case, VT J0243 is a unique example of a nascent jet, highlighting the unknown connection between supermassive black holes, the properties of their accretion flows, and jet launching.

Abstract
We report on pulse profile decomposition analysis of bright transient X-ray pulsar 1A 0535+262 using broadband Insight-HXMT observations during a giant outburst of the source in 2020. We show that the observed pulse profile shape can be described in terms of a combination of two symmetric single-pole contributions for a wide range of energies and luminosities for a fixed geometry defining the basic geometry of the pulsar. This corresponds to a slightly distorted dipole magnetic field, i.e., one pole has to be offset by ∼12° from the antipodal position of the other pole. We reconstruct the intrinsic beam patterns of the pulsar assuming that the geometry is recovered from the decomposition analysis, and we find evidence for a transition between “pencil” and “fan” beams in energy ranges above the cyclotron line energy, which can be interpreted as a transition from sub- to supercritical accretion regimes associated with the onset of an accretion column. At lower energies, however, the beam pattern appears to be more complex and contains a substantial “fan” beam and an additional “pencil” beam component at all luminosities. The latter is not related to the accretion rate and is stronger in the fading phase of the outburst. We finally discuss the results in the context of other observational and theoretical findings earlier reported for the source in the literature.
Role of Magnetic Fields in the Formation of Direct Collapse Black Holes

Published: March 2023

Abstract
Direct collapse black holes are the leading candidates for the origin of the first supermassive black holes. However, the role of magnetic fields during their formation is still unclear as none of the previous studies has been evolved long enough to assess their impact during the accretion phase. Here, we report the results from a suite of 3D cosmological magnetohydrodynamic (MHD) simulations which are evolved for 1.6 Myr comparable to the expected lifetime of supermassive stars (SMSs). Our findings suggest that magnetic fields are rapidly amplified by strong accretion shocks irrespective of the initial magnetic field strength and reach the saturation state. They stabilize the accretion disks and significantly reduce fragmentation by enhancing the Jeans mass in comparison with pure hydrodynamical runs. Although the initial clump masses are larger in MHD runs, the rapid coalescence of clumps in non-MHD cases due to the higher degree of fragmentation results in similar masses. Overall, the central clumps have masses of 105
M
⊙ and the mean mass accretion rates of ∼0.1 M
⊙ yr−1 are similar in both MHD and non-MHD cases. The multiplicity of SMSs is significantly reduced in MHD simulations. Such strongly amplified magnetic fields are expected to launch jets and outflows which may be detected with upcoming radio telescopes.

La « Bibliothèque utile » (1859-1914) est une collection pionnière de vulgarisation. Accueillie par quatre éditeurs (Dubuisson, Pagnerre, Germer-Baillière et Alcan), elle s’adresse à un public d’adultes pourvu d’instruction primaire, qui souhaite s’instruire sur des sujets variés. L’article montre la mise en œuvre d’une autodidaxie possible, essentiellement dans les livres signés par ses fondateurs, H. Leneveux et A. Corbon – eux-mêmes autodidactes et héritiers de l’associationnisme ouvrier –, avant d’analyser le discours éditorial péritextuel incitatif. À partir de quelques exemples d’ouvrages, l’article interroge les moyens par lesquels la collection s’est proposée à la lecture d’un public qu’elle s’est attaché à forger et à définir. Il montre également l’évolution de la réception dans un paysage éducatif mouvant.
Le serement a ce deu et pertinent . La délégation du droit de recevoir le serment à la cour des ducs de Bourgogne
Authors: Nosova Ekaterina 
Published: March 2023

L’article est consacré à l’analyse de l’une des composantes du processus de nomination à la cour des ducs de Bourgogne Philippe le Bon et Charles le Téméraire. Cette étude est fondée sur les lettres de nomination conservées aux Archives générales du Royaume à Bruxelles. D’après la comparaison avec les ordonnances de l’hôtel, un certain nombre d’offices appartenant à la cour ont été identifiés et 268 documents ont été sélectionnés à partir de cette liste. Malgré le petit nombre de lettres de nomination appartenant à l’époque de Philippe le Bon, il est possible de retracer l’évolution de cette tradition. Sous Philippe le Bon, presque tous les traits caractéristiques de la procédure sont établis, traits que son fils accentue par la suite. Ainsi se définit un cercle d’officiers influents auxquels le prince délègue le droit de prêter serment en son nom : premier chambellan, maître d’hôtel, le chancelier et chef du conseil. Dans le même temps, se définit l’usage d’un double serment pour l’office de conseiller et chambellan, serment prêté à la fois au chancelier et au chambellan. Charles, alors qu’il n’était encore que prince héritier et commençait à former sa cour, avait déjà renforcé cet usage. Néanmoins, il n’a jamais totalement systématisé ces évolutions : la correspondance entre ceux qui prêtent serment et ceux qui le reçoivent n’a jamais été parfaitement stable. Encore faut-il relever que le prince a continué de se réserver le droit de recevoir lui-même les serments. Bien que cette pratique de délégation du droit de recevoir le serment prive le prince d’un des plus puissants outils d’influence sur son entourage, elle lui donne l’occasion de structurer hiérarchiquement sa cour et de mettre en valeur le rôle d’un individu de son entourage.

Authors: Ullah Asma , Toth Cynthia A. , Burnett Henry W. , Butler John W. , Levy Jay H. , Benner Jeffrey D. 
Published: March 2023

Background and Objective:
Proliferative vitreoretinopathy (PVR) has been mitigated by intravitreal methotrexate (MTX) 400 μg/0.1 mL in several studies. Here, we evaluate the results from a lower dose of MTX, 200 μg/0.05 mL.

Materials and Methods:
We identified and reviewed records of patients with grade ≥C1 PVR who were treated with 200 μg/0.05 mL MTX injections: during PVR surgery and every 2 weeks thereafter.

Results:

Twenty-four eyes met inclusion criteria with a mean of 5.6 injections and follow-up ranging 6 to 56 months. The retina was reattached in 19 of 24 eyes (79%) after a single surgery and in 5 of 24 eyes (21%) after one additional PVR surgery. Visual acuity improved from baseline logMAR 1.63 to 0.97 at 12 months (
P
< .001), with 5 of 20 achieving 20/60 or better and 16 of 20 achieving 20/200 or better. One eye developed a transient corneal abrasion that resolved within 1 week.

Conclusion:
Low-dose MTX (200 μg/0.05 mL) during and after PVR surgery resulted in good rates of retinal reattachment and visual acuity recovery.

Dynamique du couvert végétal dans la Forêt Communautaire de Sambandé au Sénégal
Authors: Faye Cheikh Tidiane , Thiaw Agnès Daba , Faye Guilgane 
Published: March 2023

L'évolution de l'occupation du sol entre 1998 et 2018 dans la Forêt Communautaire de Sambandé, mise en défens en 1999 et exploitée à des fins de production de charbon de bois depuis 2007, a été appréhendée à travers des images satellitaires Landsat, une enquête ménages et des relevés floristiques collectés en 2019. Les cartographies dressées à partir des images Landsat montrent que la végétation spontanée s'est fortement reconstituée. Ce constat est partagé par la population, la part des personnes interrogées considérant que la végétation spontanée était abondante passant de 14 % pour 1998 (avant la mise en défens) à 66 % pour 2018. Cette amélioration du couvert végétal s'est traduite par une progression des savanes arbustive et arborée. Entre les deux dates, la première est passée de 43,1 à 52,1 % de la superficie de la zone d'étude et la seconde de 11,3 à 15,8 %. Dans le même temps, la savane arborée dégradée a fortement régressé, passant de 33,5 % à 14,2 % de la superficie totale. La diminution de la zone dégradée est ici la marque d'un territoire en reconstitution, d'où la concordance avec l'enquête. Toutefois les inventaires floristiques donnent une vision différente, le nombre d'individus et la diversité floristique sur les placettes n'étant pas liés par une relation simple et étroite au degré apparent de reconstitution du couvert végétal.

Authors: Abouhamzeh Beheshteh , Zare Zohreh , Mohammadi Moslem , Moosazadeh Mahmood , Nourian Alireza 
Published: March 2023

Background:
Bisphenol-S (BPS), as a new human public health concern, was introduced to the plastic industry by BPA-free labeled products following the restrictions of Bisphenol-A (BPA) as a safe alternative. However, recent research has revealed a controversial issue. In this regard, the present study aimed to review the relationship between BPS exposure and reproductive system dis/malfunction.

Methods:
PubMed and other databases were searched up to January 2021. The standard mean difference (SMD) with a 95% confidence interval (CI) was calculated for the main parameters using the random-effects model. Finally, 12 studies with 420 subjects were included in this research. Forest plot, meta-regression, and non-linear dose-response effect were calculated for each parameter by random-effects model.

Results:
Based on the results of in vitro assessment, a significant increase was found in the oxidative stress parameters, including superoxide dismutase (SMD: 0.63, 95% CI: 0.321, 0.939), thiobarbituric acid reactive substances (SMD: 0.760, 95% CI: 0.423, 1.096), and reactive oxygen species (SMD: 0.484, 95% CI: 0.132, 0.835). In addition, the hormonal assessment revealed a significant decrease in male testosterone concertation (SMD: -0.476, 95% CI: -0.881, -0.071). Moreover, in vivo examination revealed a significant decrease in hormonal parameters, such as female testosterone (SMD: -0.808, 95% CI: -1.149, -0.467), female estrogen (SMD: -2.608, 95% CI: -4.588, -0.628), female luteinizing hormone (SMD: -0.386, 95% CI: -0.682, -0.089), and female follicle-stimulating hormone (FSH) (SMD: -0.418, 95% CI: -0.716, -0.119). Besides, linear and non-linear correlations were detected in the main parameters.

Conclusion:
In conclusion, based on the current meta-analysis, BPS was suggested to be toxic for the reproductive system, similar to the other bisphenols. Moreover, a possible correlation was indicated between oxidative and hormonal status disruption induced by BPS in male and female reproductive systems dis/malfunction.

Introduction:
COVID-19 is a respiratory disease caused by infection with severe acute respiratory syndrome Coronavirus 2 (SARS-CoV-2). Thrombotic complications appear to be of particular importance in patients with COVID-19. This study aimed to investigate Changes in the level of Antiphospholipid antibodies (Anticardiolipin and Anti-β2-glycoprotein-I) and thromboembolic indices in COVID-19 patients during 3 weeks.

Methods:
This cross-sectional study was performed on adults with Covid-19 hospitalized at Al-Zahra Hospital in Isfahan. The case group includes the patients admitted to the internal ward or ICU who despite receiving prophylactic or anticoagulant doses suffer from thrombotic complications and the control group includes COVID-19 patients without thromboembolic events. The sample size of 120 people was considered. Anticardiolipin and anti-β2-glycoprotein-I antibodies, coagulation profiles including Fibrinogen, PTT, PT Troponin, ESR, CRP, and D-dimer were examined. After collection, the data were entered into spss24 software and analyzed.

Results:
The results showed that there was no statistically significant difference in the changes of anticardiolipin and anti-beta-2 glycoprotein in IgM and IgG as well as in the changes of ESR, CRP, PTT, PT, and fibrinogen in the two groups (P > 0.05).

Conclusions:
Our study showed that there was no statistically significant relationship between anti-phospholipid antibodies (anticardiolipin and anti-beta-2 glycoprotein) and thromboembolic events. Therefore anticardiolipin and anti-beta-2 glycoprotein is probably the puzzles causing thrombosis in COVID-19 patients, and other inflammatory responses should be examined among the cases.

Authors: Erdil Deniz , Bagis Nilsun , Eren Hakan , Camgoz Melike , Orhan Kaan 
Published: March 2023

Background:
Bruxism is defined as recurrent masticatory muscle activity. Although there is not an agreed treatment method for bruxism, the application of botulinum toxin A (BT-A) has become a reliable lately. This study aimed to evaluate the correlation between the changes in masseter muscle thickness and clenching habits in bruxism patients treated with BT-A.

Methods:
Twenty-five patients, 23 females and 2 males, diagnosed with possible sleep bruxism were included in the study. The Fonseca Anamnestic Index was applied to the patients to determine their clenching habits and depression levels both before the treatment, and 6 months after it. The masseter muscle thickness was measured using ultrasonography before the treatment and 3 months and 6 months after the treatment. All the patients were injected with a total of 50 U of BT-A, 25 U to each masseter.

Results:
A statistically significant decrease in masseter muscle thickness was observed in the ultrasonography 3 and 6 months after the BT-A treatment. There was a statistically significant decrease in the Fonseca scores, in which the teeth clenching habits of the patients were evaluated 6 months after the treatment. Although there was a decrease in the depression levels of the patients 6 months after the treatment, this difference was not statistically significant.

Conclusion:
When the results of this study were evaluated, it was seen that the BT-A injections are an effective, safe, and side effect-free method in the treatment of bruxism and masseter hypertrophy.
Strongly Continuous Domains
Authors: Song Yinglong , Yang Jinbo 
Published: March 2023

Strong Scott topology introduced by X. Xu and D. Zhao is a kind of new topology which is finer than upper topology and coarser than Scott topology. Inspired by the topological characterizations of continuous domains and hypercontinuous domains, we introduce the concept of strongly continuous domains and investigate some properties of strongly continuous domains. In particular, we give the definition of strong way-below relation and obtain a characterization of strongly continuous domains via the strong way-below relation. We prove that the strong way-below relation on a strongly continuous domain satisfies the interpolation property, and clarify the relationship between strongly continuous domains and continuous domains, and the relationship between strongly continuous domains and hypercontinuous domains. We discuss the properties of strong Scott topology and strong Lawson topology, which is the common refinement of the strong Scott topology and the lower topology, on a strongly continuous domain.Comment: 10 pages, 2 figures

Published: March 2023

IntroductionEvidence suggests that obesity and ageing in women are linked to angular knee abnormalities. The hip-knee-ankle (HKA) angle on a full-limb radiograph is the gold standard measure of lower limb alignment. The AI Posture Evaluation and Correction System (APECS) software is a non-radiographic mobile application designed for whole-body posture assessment. Since exposure to X-ray is associated with harmful effects, there is a need to find a safe and valid alternative for measuring HKA angle. The objective of this research was to determine the validity of the non-radiographic APECS software in comparison with standard radiographic measurement of HKA angle.MethodsThe present cross-sectional diagnostic accuracy study was conducted in a tertiary care hospital of Belagavi, Karnataka, India. Overall, 45 elderly obese females aged 60–80 years with a body mass index of 25 were included. HKA angle was marked bilaterally. Full-limb radiographs were taken and angles were marked with 2.0 version software, DXM model. For the APECS software, full-limb photographs were taken with landmarks indicated with radiant markers and angles were autogenerated by the software.ResultsThe Pearson correlation coefficient between the APECS application and the gold standard (X-ray) was 0.9874 (98.74% of matching). The agreement between standard radiograph and the average of all examiners’ APECS Pro measurements (including right and left sides) equalled 94.64% (kappa = 0.8323; <i>p</i> = 0.001), which suggests very good agreement.ConclusionsThe APECS application demonstrated a high percentage of matching (98.74%) and agreement (94.64%), indicating its excellent validity in measuring HKA angle.

IntroductionThis study was conducted to compare the prevalence of trunk rotation in selected urban and countryside areas in Egypt.MethodsOverall, 840 male students aged 10–15 years were divided into 2 equal groups: group A, representing urban schools, and group B, representing countryside schools. Both groups were first screened with the Adams forward bend test; then, the Scoliometer HD application was used to determine the angle of trunk rotation. Children with a reading of 7° or more (≥ 20° Cobb angle) were referred to a medical facility and their parents were informed about the findings.ResultsIn group A, the Adams forward bend test showed a higher prevalence of trunk rotation (41.43%) than in group B (17.14%). The Scoliometer HD application readings (≥ 7°) indicated a significant difference between the 2 groups: group A result was 12.61% and group B result was 5%.ConclusionsMale students of urban schools exhibit a higher prevalence of trunk rotation than those of countryside schools.

Published: March 2023

IntroductionPlyometric exercise is known as one of the key components of neuromuscular training programs. It is also possible to obtain higher muscular activity by exercising on tatami and mats. The purpose of the study was to evaluate the activity of hamstring and gluteus medius in 7 typical plyometric exercises on 3 different surfaces and identify the best exercises and surfaces that would further increase hamstring and gluteus medius activity.MethodsThe study involved 20 male athletes. The participants performed 7 plyometric exercises on 3 surfaces: ground, tatami, and mat. The electromyographic activity of muscles was recorded with a ME6000 device in 2 phases: feedforward and feedback. To analyse the data, 2-way ANOVA with repeated measures and a Bonferroni post-hoc test were used.ResultsGluteus medius was most active in the feedforward phase in single-leg frontal plane hop (SLFPH), and in the feedback phase in SLFPH and single-leg sagittal plane hop (SLSPH) (<i>p</i> = 0.001). The medial hamstring and lateral hamstring showed the highest values of activity in the feedforward phase in SLSPH, SLFPH, and double-leg sagittal plane hop (DLSPH) (<i>p</i> = 0.001). There was no significant difference between the surfaces (<i>p</i> > 0.05).ConclusionsSLSPH, DLSPH, and SLFPH improve the recruitment and the strength of gluteus medius and hamstrings and should be given considerable attention in training programs. Exercise on the ground, tatami, and mattress is allowed and in terms of the purpose of the research, there is no difference between them.
