Spectral Lags of 90 Swift Gamma-Ray Bursts and the Constraint on the Lorentz Invariance Violation
Authors: Liao Bin , Zou Yuan-Chuan , Lei Wei-Hua 
Published: June 2024

Abstract
The arrival times of photons with different energy could be different, even when they are emitted from the same source simultaneously. Such a spectral lag is a common property among high-energy astrophysics phenomena like gamma-ray bursts (GRBs). The potential violation of the Lorentz invariance caused by quantum fluctuations in background spacetime metrics could cause the spectral lag. In this paper, we try to make a constraint on Lorentz invariance violation (LIV) with multiple energy bands light curves of GRBs. With a sample of 90 Swift GRBs with redshifts, we calculate their spectral offsets from four fixed energy bands within their source frame. With help from the cross-correlation function and kernel smooth procedure, we extract improved spectral shifts. By using these more general spectral lags, we obtain an upper limit on LIV, equivalent to a lower limit on the quantum-gravitational energy scale of E
QG ≥ 2.2 × 1014GeV.
Statistical Study of the Sub-ion-scale Magnetic Holes in the Lunar Space Environment
Authors: Wei Jiayun , Wang Guoqiang 
Published: June 2024

Abstract
Sub-ion-scale magnetic holes play a significant role in electron transportation and energy dissipation. In the upstream region of the terrestrial bow shock, they are expected to originate from the upstream solar wind as well as the foreshock. The Moon can move into the solar wind; whether it can affect the observation of the sub-ion-scale magnetic holes is unclear. Here, we statistically investigate 268 sub-ion-scale magnetic holes in the lunar space environment based on observations of the Acceleration, Reconnection, Turbulence and Electrodynamics of the Moon’s Interaction with the Sun mission. The median duration of these magnetic holes is ∼0.31 s, and the median size of their cross sections is ∼0.5 ρ
i or ∼38.9 ρ
e. We regard an isolated or a train of magnetic holes as an event; thus, these magnetic holes belong to 207 events. The data at X
SSE < 0 and |Y
SSE| < 2 R
M (lunar radii) account for ∼21.7% of all observed data, but ∼89.4% of the events are observed in this region, suggesting that they are more likely to occur in the lunar wake. Furthermore, their occurrence rates in the lunar wake are much larger in the region close to its boundary than in other wake regions. And the occurrence rates in the lunar wake near the boundary at X
SSE > −3 R
M are larger in the dawnside than that in the duskside. These observations suggest that the region in the lunar wake close to its boundary is a possible source of sub-ion-scale magnetic holes.
Multimode δ Sct stars from the Zwicky Transient Facility Survey
Authors: Jia Qi , Chen Xiaodian , Wang Shu , Deng Licai , Luo Yangping , Jiang Qingquan 
Published: June 2024

Abstract
We obtain the largest catalog of multimode δ Sct stars in the northern sky to date using the Zwicky Transient Facility (ZTF) Data Release 20. The catalog includes 2254 objects, of which 2181 are new to our study. Among these multimode δ Sct stars, 2142 objects are double-mode δ Sct, while 109 objects are triple-mode δ Sct and three are quadruple-mode δ Sct. By analyzing the light curves in the r and g bands of the ZTF, we determine the basic parameters of multimode δ Sct stars, including the periods and amplitudes. Periods are checked by comparison with the Optical Gravitational Lensing Experiment catalog of double-mode δ Sct stars. On the Petersen diagram, multimode δ Sct stars form six sequences. We find that in Galactic coordinates, the periods of 1O/F double-mode δ Sct stars at high latitudes are shorter than those of 1O/F double-mode δ Sct stars in the disk, due to metallicity variations. In the future, our catalog can be used to establish the period–luminosity relation and the period–metallicity relation of double-mode δ Sct stars, and to study the Galactic structure.
Distribution of the genus Platycerus Geoffroy (Coleoptera, Lucanidae) in Italy
Authors: Scaccini Davide , Bartolozzi Luca , Zilioli Michele , Di Giulio Andrea , Ruzzier Enrico 
Published: June 2024

Stag beetles are saproxylic species that are associated with deadwood in the larval stage and play an important role in forest ecosystem dynamics. In Italy, Platycerus caprea and Platycerus caraboides are two small, elusive stag beetle species, whose known distribution is often limited or referring to old records.
The present contribution increases the knowledge on the Italian distribution of P. caprea and P. caraboides, adding 70% more sites when compared to previously published records. Ecological traits, especially related to the altitude-elevation distribution in Italy, are also described for these saproxylic beetles.
Fractional integral approach on nonlinear fractal function and its application
Authors: Kavitha C. , Gowrisankar A. 
Published: June 2024

The shape and dimension of the fractal function have been significantly influenced by the scaling factor. This paper investigated	the fractional integral of the nonlinear fractal interpolation function corresponding to the iterated function systems employed by Rakotch	contraction. We demonstrated how the scaling factors affect the flexibility of fractal functions and their different fractional orders of the	Riemann fractional integral using certain numerical examples. The potentiality application of Rakotch contraction of fractal function	theory was elucidated based on a comparative analysis of the irregularity relaxation process. Moreover, a reconstitution of epidemic curves from the perspective of a nonlinear fractal interpolation function was presented, and a comparison between the graphs of linear and nonlinear fractal functions was discussed.
Écrire la culture : histoire et perspectives du journalisme culturel
Authors: Alexis Lucie , Sciullo Flore Di 
Published: July 2024

Résumé : Critique culturelle, prescription, recommandation, guide, promotion, intermédiation, etc., le journalisme culturel charrie dans son sillage un grand nombre de notions, certes semblables, mais qui impliquent des approches et des usages différenciés. Reste alors à les identifier, les répertorier, les analyser. Il s'agit d'examiner spécifiquement les pratiques éditoriales de ce type de journalisme, dans les entreprises médiatiques et les institutions culturelles. Où se situe sa spécificité, d’un point de vue discursif, sémantique, morphologique ? Dans un contexte de transition numérique et de facilitation des prises de parole amateures, comment s’assume et se transforme la critique culturelle ? L’engagement et l’implication du critique dans les arènes publiques constituent-ils un vecteur de pérennisation de son utilité en tant que prescripteur ? C’est à ces quelques questions que ce dossier, comme le texte qui l’introduit, tente de répondre, dans une perspective interdisciplinaire et transnationale, en identifiant plusieurs axes de réflexion : les effets de légitimation du journalisme culturel pour des « niches » dans les productions culturelles, les rapprochements voire les collusions entre journalisme culturel et productions institutionnelles, enfin la politisation du journalisme culturel et son entrelacement avec la médiatisation de conflits internationaux.
La passion comme convention de travail : les magazines français consacrés au cinéma fantastique
Authors: Mazel Quentin 
Published: July 2024

Résumé : Les magazines français entièrement consacrés au cinéma fantastique apparaissent au tournant des années 1980 dans le sillage de nombreux fanzines. Les personnes qui animent ces publications appréhendent leur travail à travers le prisme de la passion. Cette contribution interroge la manière dont le contexte de professionnalisation et de développement de ces publications a conduit à l’expression d’une convention de travail associée à la passion. Il étudie la manière dont des critiques professionnels sont traversés par des logiques propres au milieu amateur. Il décrit le contexte d’apparition de cette presse spécialisée, les propriétés sociales et les relations qui unissent les journalistes de ce segment, pour ensuite analyser la manière dont la « passion » encadre la distribution, l’organisation et la réalisation du travail.
Le nouveau visage médiatique des organisations culturelles : le cas de We are Europe
Authors: Jutant Camille 
Published: July 2024

Résumé : À partir du cas d’étude du site internet We Are Europe, fruit d’un partenariat entre des festivals de musiques électroniques, cet article étudie un récent mouvement dans le champ culturel : la mise en ligne et l’animation, par les structures artistiques, de « médias ». L’objectif est de comprendre si le dispositif We Are Europe est une stratégie de promotion des acteurs culturels ou une forme émergente de journalisme culturel. L’analyse sémiotique du site montre que des formats éditoriaux variés (l’archivage, le reportage) et des logiques énonciatives plurielles s’enchâssent au service d’un « médiactivisme » faisant la promotion d’une communauté diversifiée de locuteurs et d’un traitement d’enjeux à la fois culturels et politiques à l’échelle européenne.
Le tournant éducatif et la (dé)politisation du journalisme culturel en Russie
Authors: Vokuev Nikolai 
Published: July 2024

Résumé : L’article traite des aspects politiques des changements dans le journalisme culturel en Russie dans les années 2010 et au début des années 2020. Il se concentre sur l’émergence de médias culturels à tendance éducative (tournant éducatif) dans le contexte de la réaction politique et de la monopolisation de l’information, de la culture et de la production de connaissances par l’État russe commencé durant le troisième mandat de Vladimir Poutine. Trois périodes de dynamique politique dans le journalisme culturel sont identifiées : la pénétration de sujets politiques dans les médias culturels pendant les manifestations anti-Poutine de 2011-2012 (politisation du culturel), le déplacement ultérieur des controverses politiques dans l’espace du discours culturel (culturalisation du politique) et l’émergence de nouveaux médias décoloniaux dans le contexte de la guerre en Ukraine (repolitisation du culturel). La recherche est fondée sur des entretiens avec des éditeurs des médias culturels à vocation éducative.
L’acceptabilité sociale, une doxa ? Évitons de jeter le bébé avec l’eau du bain.
Authors: Gendron Corinne , Yates Stéphanie , Friser Alice 
Published: July 2024

Résumé : L’acceptabilité sociale reste une expression controversée car elle a longtemps été utilisée par les promoteurs pour désigner des stratégies communicationnelles visant à éviter ou à réduire la controverse autour de certains projets. Pourtant, comme d’autres expressions avant elle, le sens que lui donnent les acteurs sociaux a évolué au fil des ans au point que l’expression peut être envisagée comme le lieu d’un véritable travail social concernant les conditions de légitimité des projets. En parallèle, des chercheurs se sont penchés sur les facteurs permettant d’expliquer l’attitude des populations à l’égard des projets ou des décisions publics, ouvrant la voie à une véritable théorisation de l’acceptabilité sociale, qui s’inscrit dans la perspective d’une démocratie plus participative. L’invocation de l’acceptabilité sociale à l’occasion de la pandémie peut être analysée comme discours, mais ne doit jamais se confondre avec l’analyse que peut en faire le chercheur sous le prisme du concept d’acceptabilité sociale. Au Québec, bien que l’expression ait été peu utilisée par les pouvoirs publics, l’anticipation d’une adhésion des populations aux mesures sanitaires fut un élément déterminant du niveau de restrictions imposé, ce qui s’explique aisément : sans acceptabilité sociale, les mesures n’auraient pas été respectées et seraient donc devenues inopérantes. Il s’agissait donc d’une condition première de leur effectivité.

Published: July 2024

Résumé : Depuis la moitié du xxe siècle, la nouvelle théorie des messages et de la régulation par l’information qu’est la cybernétique n’a cessé d’évoluer et de se ramifier dans de multiples directions. L’ouvrage Cybernétique et société. L’usage humain des êtres humains, qui propose aux lecteurs une présentation de la cybernétique allégée de ses fondements mathématiques et orientée vers ses conséquences humaines, sociales et politiques, fut au début des années 1950 un véritable succès éditorial, à l’instar de l’ouvrage fondateur qui l’a précédé de deux ans, La Cybernétique. Information et régulation dans le vivant et la machine. L’objet de cet article est de revenir sur le contexte scientifique et géopolitique particulier dans lequel prit corps la cybernétique en lien avec la trajectoire singulière d’un savant hors normes, Norbert Wiener. Nous reviendrons également de façon approfondie sur les concepts, la pensée et la démarche d’écriture présentée dans Cybernétique et société. L’usage humain des êtres humains avant de dérouler quelques fils de l’héritage de la cybernétique, notamment en sciences de l’information et de la communication.
Real-world utility of serological tests in patients with suspected scrub typhus in the Republic of Korea: A single-center, retrospective, observational study
Authors: Kim Seulki , Kim A Reum , Lim Seungjin , Lee Su Jin , Bae Moonsuk 
Published: June 2024

Objective:
Serological tests are widely used for scrub typhus diagnosis; however, their limitations are evident. This study aims to assess their practical value in clinical settings.

Methods:
We analyzed the data of adult patients with suspected scrub typhus who visited a tertiary care hospital in the Republic of Korea from September to December from 2019 to 2021. The included patients had an acute fever and at least one of the following ten secondary findings: myalgia, skin rash, eschar, headache, thrombocytopenia, increased liver enzyme levels, lymphadenopathy, hepatomegaly, splenomegaly, and pleural effusion. The diagnoses were grouped as scrub typhus or other diseases by two infectious disease physicians.

Results:
Among 136 patients who met the eligibility criteria, 109 had scrub typhus and 27 had different diseases. Single and paired total antibodies using immunofluorescence assay (IFA), and total antibodies using immunochromatography-based rapid diagnostic testing (ICT) were measured in 98%, 22%, and 75% of all patients, respectively. Confirmation using paired samples for scrub typhus was established at a median of 11 [interquartile range (IQR) 10-16] days following the first visit. Among the 82 admitted patients, the median admission time was 9 (IQR 7-13) days. According to IFA, 58 (55%) patients with scrub typhus had total immunoglobulin titers ≥1:320, while 23 (85%) patients with other disease had titers < 1:320. Positive ICT results were observed in 64 (74%) patients with scrub typhus and 10 (67%) patients with other diseases showed negative ICT results.

Conclusions:
Serological testing for scrub typhus is currently insufficient for decision-making in clinical practice.
Griscelli syndrome type 2: Rare 3 cases from Iraq
Authors: AL Ani Mouroge Hashim , Yahya Farah Samer 
Published: June 2024

Abstract
Griscelli syndrome (GS) is multisystem disorder of three subtypes, hereditary autosomal recessive diseases characterized by inborn silvery gray hair, partial skin albinism & immune deficiency. It was first reported by Griscelli et al. in 1978. The pathogenic defect in the RAB27Agene is responsible both for inborn pigmentary impairment and for triggering the Hemophagocytic lymphohistiocytosis (HLH) a rapidly progressive, life-threatening condtion. We present two cases from different governorates who were diagnosed with GS by achieving genetic study: the first case was saved by successful bone marrow transplantation, whereas the second case died before managing to do the procedure, being rare and underdiagnosed disease end with misdiagnosis and mismanagement.
Hemophagocytic syndrome: Laboratory and molecular characterization
Authors: Yaseen Nooran Salem , Ali Sadiq Khalaf , Aziz Hussam Saadi 
Published: June 2024

Abstract:

BACKGROUND:
Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening syndrome of fever, cytopenia, and organomegaly resulting from immune activation and cytokine storm. The syndrome can occur as a primary/familial form mostly affecting infants and young children or as an acquired form secondary to an underlying pathology (infection, malignancy, and autoimmune disease) that may have an underlying genetic predisposition, including mutations or polymorphisms.

PATIENTS AND METHODS:
This case–control study was conducted in Basra, Iraq. Thirty-four pediatric and adult patients with peripheral cytopenia attributed to bone marrow (BM) hemophagocytosis enrolled with 34 healthy individuals (age and sex matched) included as a control group. Whole blood was tested for complete blood count and screened for the presence of mutations in the perforin gene by polymerase chain reaction amplification; in addition, serum samples were tested for soluble CD25, ferritin, and triglycerides (TGs).

RESULTS:
The mean hemoglobin level and platelets count were significantly lower in HLH patients compared to the control group (P < 0.001), while there was no significant statistical difference regarding neutrophils count (P > 0.05). Soluble CD25 (s.IL-2R) testing revealed inconsistent results; serum ferritin and TGs were significantly higher in HLH patients compared to the control group (P < 0.001). About nine cases were genetically proven to have primary HLH; all were infants under the age of 6 months. Perforin gene mutations were detected in 38.8% (n = 7) of tested subjects. The novel frameshift mutation of the perforin gene (c.218_224del) was identified in four cases. Fifteen different perforin gene polymorphisms were detected in both case and control groups. Six out of nine infants with primary HLH did not survive, while the remaining three cases underwent BM transplantation.

CONCLUSION:
Early diagnosis of HLH is often challenging; this study should increase awareness of the prevalence of familial HLH among infants; such cases require early recognition and referral to hematopoietic stem cell transplantation.
Barriers and Facilitators for Physical Activity in Older Adults
Authors: Patel Jahanvi Dineshbhai , Sheth Megha , Jain Anjali 
Published: June 2024

Abstract

Background:
Physical activity (PA) has many benefits in preventing diseases and is essential for maintaining physical and mental well-being. Even so, only a few older people regularly participate in PA. Both facilitators and barriers affect physical exercise in older people.

Aim:
This study aims to find barriers and facilitators of PA in older adults.

Materials and Methods:
This observational study used face-to-face interviews to gather data from older people (age >60 years) of a community of Ahmedabad. A set of questions was prepared to identify facilitators and barriers to PA in older adults. Data were collected from 150 older people through the convenience sampling method.

Statistical Analysis:
Descriptive statistics was used.

Results:
One hundred and fifty participants with a mean age of (67.92 ± 5.95) years participated in the study, including 71 (47.3%) females and 79 (52.7%) males. The results show that the common barriers to PA in older adults are health problems (31.7%), lack of time (30.2%), lack of motivation (46%), and weather (38%). Facilitators are beliefs that PA may prevent health problems (81%), improve health conditions (81%), enjoyment of activity (63.5%), family and friends’ involvement (47.6%), having the opportunity for PA-related support and social interaction with the participants (61.9%), living in a walkable area (60.3%), convenient/nearby PA locations (50.8%), and even walking surfaces (63.5%).

Conclusion:
Barriers to PA in older people were health problems, a lack of time, a lack of motivation/laziness, a lack of guidance from a professional, weather and environment such as traffic and lack of green areas. Facilitators believed that PA may prevent health problems; having the opportunity for PA-related support and social interaction/participation, living in a walkable area, even walking surfaces, and enjoyment of PA were also facilitators for PA among older adults.

Published: June 2024

Abstract
Crohn’s disease (CD) is segmental, noncontinuous, subacute, or chronic inflammation that can affect any part of the digestive tract from the mouth to the anus, with a predilection for the distal ileum and colon. The incidence of CD is increasing and is now 5–10 per 100,000, with a prevalence of 50–100 per 100,000. A 47-year-old patient presented to the outpatient department of the Department of Kayachikitsa, Ch. Brahm Prakash Ayurved Charak Sansthan, New Delhi, with complaints of spasmodic abdominal pain and passage of mucoid stool with increased frequency of defecation from last 2 months. This case was diagnosed as CD in the colonoscopy report. The patient was treated with Panchkarma procedures and Ayurvedic oral drugs and found satisfactory results with no side effects. Colonoscopy, contrast-enhanced computed tomography enterography, and liver function test were considered objective parameters of assessment. Improvement was assessed on the basis of relief in subjective and objective parameters. After the course of treatment, significant improvement was seen in the grading of subjective parameters and laboratory investigation. This case study illustrates that Ayurvedic medicament can be the choice for treating ailments of the gastrointestinal tract.
Outcome of Trial of Labor after Cesarean Delivery: Evaluating the Flamm Scoring System in Two Hospitals in Cameroon: A 5-year Retrospective Study
Authors: Ngeh-Nkeng Alembong Eleanor , Milton Forchap Nkemanjong , Samuel Nkengfua , Adolphe Elong Felix , Thomas Egbe Obinchemti 
Published: June 2024

Abstract

Background:
Outcomes of trial of scar (TOS) correlate well with predictions provided by vaginal birth after cesarean scoring systems. In Cameroon, there is limited data on the implementation and effectiveness of these scoring systems, as well as the materno-fetal outcomes of TOS.

Objectives:
The objective was to utilize the Flamm score in predicting the success of TOS, and to evaluate the maternal and fetal outcomes observed following TOS in Yaounde and Douala Gyneco-Obstetric and Pediatric Hospitals from 2017 to 2021.

Material and Methods:
We included files of 310 parturient women with single transverse lower uterine segment cesarean section, who had TOS. Data on sociodemographic, reproductive health, Flamm scoring, and labor outcomes were documented using a structured data extraction form and analyzed using the Statistical Package for the Social Sciences version 25.

Results:
Of the 310 patients, 73.9% had successful vaginal deliveries (VDs) and 26.1% had repeated emergency cesarean. Flamm score predictions were associated with TOS outcomes (P = 0.0001), with mean score of 5.87 ± 0.01 for successful VD compared to 3.72 ± 0.126 for repeat cesarean. Probability of successful VD increased with Flamm score, ranging from 0% for scores of two to 100% for scores > 7, with a cutoff score of 4.5 (Se = 75.0%, Sp = 75.3%). The main maternal complication was one uterine rupture (0.32%) and neonatal complications were three stillbirths (0.98%) and one early neonatal death (0.32%) after repeat cesarean.

Conclusions:
TOS is associated with high success rates in tertiary hospitals in Cameroon. Applying Flamm score will improve the chances of a successful VD following TOS, and should be encouraged.
