Non-Minimally Coupled Electromagnetic Fields and Observable Implications for Primordial Black Holes
Authors: Jana Susmita , Shankaranarayanan S. 
Published: June 2024

General relativity (GR) postulates have been verified with high precision, yet our understanding of how gravity interacts with matter fields remains incomplete. Various modifications to GR have been proposed in both classical and quantum realms to address these interactions within the strong gravity regime. One such approach is non-minimal coupling (NMC), where the space-time curvature (scalar and tensor) interacts with matter fields, resulting in matter fields not following the geodesics. To probe the astrophysical implications of NMC, in this work, we investigate non-minimally coupled electromagnetic (EM) fields in the presence of black holes. Specifically, we show that primordial black holes (PBHs) provide a possible tool to constrain the NMC parameter. PBHs represent an intriguing cosmological black hole class that does not conform to the no-hair theorem. We model the PBH as a Sultana–Dyer black hole and compare it with Schwarzschild. We examine observables such as the radius of the photon sphere, critical impact parameter, and total deflection angles for non-minimally coupled photons for Schwarzschild and Sultana–Dyer black holes. Both the black hole space-times lead to similar constraints on the NMC parameter. For a PBH of mass M=10−5 M⊙, the photon sphere will not be formed for one mode. Hence, the photons forming the photon sphere will be highly polarized, potentially leading to observable implications.

Relevance. An essential component of the treatment and prevention of periodontal diseases is regular individual oral hygiene. Educating patients on effective hygiene practices using toothpaste with anti-inflammatory properties can significantly reduce gingivitis symptoms. Our study evaluated the impact of toothpaste containing octadecafluorodecahydronaphthalene on periodontal tissues among international students who experienced a change in residence.Material and methods. Over 10 days, we observed a group of 26 international students studying at Kirov State Medical University, who used toothpaste containing perfluorodecalin and identical toothbrushes twice daily. The study included index assessments (OHI-S, PMA), as well as microbiological and biochemical analyses. Descriptive and analytical statistical methods were employed.Results. Positive clinical dynamics were observed, with reductions in OHI-S and PMA indices. There was a decrease in the total microbial count and specific types of periodontopathogenic microorganisms. Additionally, clinical improvement in periodontal tissue condition (gingival mucosa) was noted, attributed to the effects of perfluorinated compounds on periodontal microcirculation. The product's anti-plaque and anti-inflammatory effects were confirmed through clinical, microbiological, and biochemical methods.Conclusion. Daily use of toothpaste with octadecafluorodecahydronaphthalene (perfluorodecalin) had a beneficial effect on the condition of periodontal tissues, reducing inflammation by altering the microbiota structure within the biofilm and decreasing the number of periodontopathogenic microorganisms.
Signature of High-amplitude Pulsations in Seven δ Sct Stars via TESS Observations

Published: June 2024

Abstract
The regular behavior of the pulsations of high-amplitude δ Sct (HADS) stars gives a greater chance to investigate the interiors of stars. We analyzed seven HADS stars showing peak-to-peak amplitudes of more than 0.3 mag that were newly observed by TESS. We obtained that TIC 374753270, TIC 710783, and TIC 187386415 pulsate in fundamental radial mode; also, TIC 130474019 and TIC 160120432 show double radial modes. On the other hand, TIC 148357344 and TIC 278119167 demonstrate triple-mode behavior. Our analysis shows that these seven stars are close to the red edge of the (inside) instability strip in the Hertzsprung–Russell diagram. The fundamental mode of these seven targets follows the period–luminosity (PL) relation for δ Sct stars. However, TIC 278119167 deviates slightly from the fundamental PL relation. The double-mode and triple-mode HADS stars (TIC 130474019, TIC 160120432, TIC 148357344, and TIC 278119167) are in agreement with the period ratio ranges (fundamental to first and second overtones). Using the information of 176 HADS stars (Netzel and Smolec), we find a scaling relation (

An Outflow-driven Water Maser Associated with Positive Black Hole Feedback in the Dwarf Galaxy Henize 2–10
Authors: Gim Hansung B. , Reines Amy E. , Momjian Emmanuel , Darling Jeremy 
Published: June 2024

Abstract
Henize 2–10 is a dwarf galaxy experiencing positive black hole (BH) feedback from a radio-detected low-luminosity active galactic nucleus. Previous Green Bank Telescope (GBT) observations detected a H2O “kilomaser” in Henize 2–10, but the low angular resolution (33″) left the location and origin of the maser ambiguous. We present new Karl G. Jansky Very Large Array observations of the H2O maser line at 22.23508 GHz in Henize 2–10 with ∼2″ resolution. These observations reveal two maser sources distinct in position and velocity. The first maser source is spatially coincident with the known BH outflow and the region of triggered star formation ∼70 pc to the east. Combined with the broad width of the maser (W
50 ∼ 66 km s−1), this confirms our hypothesis that part of the maser detected with the GBT is produced by the impact of the BH outflow shocking the dense molecular gas along the flow and at the interface of the eastern star-forming region. The second maser source lies to the southeast, far from the central BH, and has a narrow width (W
50 ∼ 8 km s−1), suggesting a star formation–related origin. This work has revealed the nature of the H2O kilomaser in Henize 2–10 and illustrates the first known connection between outflow-driven H2O masers and positive BH feedback.
T-ReX: The Tarantula—Revealed by X-Rays
Authors: Townsley Leisa K. , Broos Patrick S. , Povich Matthew S. 
Published: June 2024

Abstract
The Tarantula Nebula (30 Doradus, 30 Dor) is the most important star-forming complex in the Local Group, offering a microscope on starburst astrophysics. At its heart lies the exceptionally rich young stellar cluster R136, containing the most massive stars known. Stellar winds and supernovae have carved 30 Dor into an amazing display of arcs, pillars, and bubbles. We present first results and advanced data-processing products from the 2 Ms Chandra X-ray Visionary Project, “The Tarantula—Revealed by X-rays” (T-ReX). The 3615 point sources in the T-ReX catalog include massive stars, compact objects, binaries, bright pre-main-sequence stars, and compact young stellar (sub)clusters in 30 Dor. After removing point sources and excluding the exceptionally bright supernova remnant N157B (30 Dor B), the global diffuse X-ray maps reveal hot plasma structures resolved at 1–10 pc scales, with an absorption-corrected total-band (0.5–7 keV) X-ray luminosity of 2.110 × 1037 erg s−1. Spatially resolved spectral modeling provides evidence for emission lines enhanced by charge-exchange processes at the interfaces. We identify a candidate for the oldest X-ray pulsar detected to date in 30 Dor, PSR J0538-6902, inside a newly resolved arcuate X-ray wind nebula, the Manta Ray. The long temporal baseline of T-ReX allowed monitoring of dozens of massive stars, several showing periodic variability tied to binary orbital periods, and captured strong flares from at least three low-mass Galactic foreground stars.
Divorce et parentalité en Algérie : analyses exploratoires
Authors: Ben Hounet Yazid 
Published: June 2024

Cet article est une première contribution, exploratoire, visant à articuler la pratique du droit du divorce et ses effets sur la parentalité au-delà de la séparation. Notre propos est de rendre compte de la manière dont la parentalité et l’intérêt de l’enfant sont appréhendés dans le droit de la famille algerienne et dans ses applications concrètes, sur le terrain, et ce à partir d’une étude de jugements établis par la cour de justice de la wilaya d’Ain Temouchent. Le droit de la famille et les jugements mentionnent à plusieurs reprises l’intérêt de l’enfant. On observe cependant que la parentalité au-delà du divorce ne semble se concevoir que de manière homogène et a priori : la garde est généralement attribuée à la mère – à moins d’un désistement – et le père se voit accorder un devoir d’entretien et un droit de visite les weekends et jours fériés. L’intérêt de l’enfant se rapporterait essentiellement à la dimension matérielle et éducative de la parentalité. Les tâches parentales apparaissent implicites et relevant d’une vision conçue comme « naturelle » de la répartition des rôles parentaux.
Esquisse d’un portrait de Charles Batteux en esthéticien des vertus : du goût, du génie et de l’intelligence
Authors: Garncarzyk Dimitri 
Published: June 2024

Cet article a pour but de relire la théorie du goût (notion aussi centrale que problématique dans l’esthétique du XVIIIe siècle) selon Charles Batteux (1713-1780) au regard de la théorie contemporaine des vertus esthétiques telle que la présente notamment Roger Pouivet (2006, 2017), dans l’optique d’actualiser la lecture de Batteux et de rendre exploitable sa philosophie de la littérature dans un cadre analytique. La première partie défend l’idée que le goût selon Batteux est une vertu épistémique et esthétique au sens de Pouivet, qui fonctionne comme un juste milieu entre deux vices intellectifs. La seconde partie examine le positionnement de cette vertu esthétique par rapport à deux autres vertus intellectives discutées par Batteux : l’intelligence et le génie. On suggère en conclusion que cette lecture de Batteux rend compte de l’ambivalence des « passions douces » d’une façon exploitable dans le discours esthétique contemporain.
La rhétorique socratico-platonicienne
Authors: Renaud François 
Published: June 2024

Des études récentes ont démontré que la critique de la rhétorique dans le Gorgias comporte elle-même une dimension rhétorique. L’analyse qui suit porte uniquement sur la première partie du dia­logue - l’entretien entre Socrate et Gorgias - à partir de deux points de vue complémentaires : (1) adaptée à la personnalité et aux opi­nions de Gorgias, l’argumentation de Socrate contrefait et transpose des procédés de la rhétorique de l’époque, mais avec une visée pro­treptique et éthique plutôt qu’éristique ; (2) auteur du dialogue, Platon y met en œuvre des stratégies, évidemment distinctes des stratégies argumentatives de Socrate personnage - tout comme le Gorgias histo­rique est distinct du Gorgias créé par Platon. Cette distinction permet d’interpréter l’ironie et la communication indirecte de Socrate per­sonnage d’une part et de Platon auteur d’autre part.
Le Socrate d’Épictète
Authors: Gourinat Jean-Baptiste 
Published: June 2024

Selon un critère purement statistique, Socrate pourrait apparaître comme la figure dominante de la philosophie d’Épictète, bien qu’il n’y ait pas d’Entretien consacré à la figure de Socrate. Cet article cherche donc à comprendre pourquoi et comment Épictète a décrit la figure de Socrate. Il examine successivement les sources utilisées par Épictète, la façon dont il les utilise, puis le portrait construit selon ces procédés. Épictète choisit des traits compatibles avec son stoïcisme : valorisation de la dialectique, souci de « ce qui est en notre pouvoir », piété, mort stoïque. Mais surtout , la stratégie d’Épictète lui permet d’apparaître comme un nouveau Socrate. La vie de Socrate constitue un modèle, que son absence complète de dogmatisme rend propre à toutes les récupérations philosophiques possibles.
Le Socrate de Dion Chrysostome
Authors: Brancacci Aldo 
Published: June 2024

Socrate est le philosophe le plus souvent mentionné dans les écrits de Dion Chrysostome : il paraît avoir eu plus d’influence sur sa personnalité intellectuelle qu’on ne l’a supposé jusqu’ici. Pour tracer le portrait de Socrate, Dion emprunte, non à Platon ou à la tradition académique, mais à la tradition cynico-stoïcienne dérivée d’Antis­thène : à l’encontre de l’éternel questionneur platonicien, le Socrate de Dion professe des doctrines « positives ». Ce choix de la part de Dion peut s’expliquer par les motivations qui inspirèrent, pour l’essentiel, son activité littéraire et politique sous Nerva et Trajan, et par sa vision du philosophe en conseiller du prince.
La vie politique depuis les oflags et stalags allemands. Laboratoire et anamorphose de l’opinion française des « années troubles »
Authors: Richard Delphine 
Published: June 2024

À la suite de la débâcle de l’armée française au printemps 1940, près d’1,6 million de soldats français sont envoyés en Allemagne comme prisonniers de guerre. Détenus dans des camps militaires jusqu’à leur libération par les Alliés en 1945, ces Français dans la force de l’âge subissent alors l’expérience très singulière de cette captivité de guerre. Enjeu central de la politique de collaboration entre Vichy et le Reich, cet échantillon de la société française vit ainsi cinq années en plein cœur du territoire allemand sous surveillance de la Wehrmacht, dans le monde clos des stalags et des oflags. Coupés de leurs proches et de leur patrie, ils tentent par tous les moyens de maintenir le lien avec la France malgré l’enfermement et l’éloignement. Des sources variées nous permettent d’appréhender leur perception de la vie politique française depuis leurs camps allemands, nous renseignant sur les opinions et attitudes qui s’y développent passés les quelques mois qui suivent le profond traumatisme de la défaite. Dans un contexte où les prisonniers sont à la fois désinformés et instrumentalisés, le pétainisme connaît de longues heures de gloire. Mais cette adhésion semble correspondre pour la majorité de ces Français en exil à l’expression d’une forme de patriotisme sommaire dans leur contexte où seule la figure de Pétain incarne la France. Si cette opinion manifestement dominante évolue lentement et tardivement vers un ralliement massif à la Résistance dans les derniers mois de la guerre, le processus ne va pas sans chevauchement et ambivalences : il ne s’agit pas d’un simple cheminement linéaire du pétainisme vers le gaullisme. L’étude de cette « opinion » sous cloche dessine ainsi une forme d’anamorphose de l’opinion publique française troublée des années noires, complétant et reflétant toute sa complexité.
A study on beneficial impact of the use of medium-molecular-weight hydroxyethyl starch in granulocyte apheresis using continuous-flow cell separator Spectra Optia: A retrospective single-center study at a tertiary care oncology center
Authors: Pathak Amardeep , Panda Devasis , Tejwani Narender , Mehta Anurag 
Published: June 2024

Abstract:

INTRODUCTION:
Granulocyte transfusion is one of the best therapeutic modalities in prolonged neutropenic patients with severe bacterial/fungal infections. Granulocyte harvest using conventional acid citrate dextrose (ACD) anticoagulant (ACD-A) by apheresis is not satisfactory in comparison to the use of hydroxyethyl starch (HES), but the latter is associated with various adverse events, especially with high-molecular-weight HES.

AIMS AND OBJECTIVE:
This study aimed to assess the beneficial impact of the use of medium-molecular-weight (MMW)-HES and trisodium citrate combination over ACD-A in granulocyte apheresis when using Spectra Optia.

MATERIALS AND METHODS:
This was a retrospective study comparing granulocyte harvest results with the use of ACD or HES and trisodium citrate combination. All the donors in both the groups received single 600 μg of granulocyte colony-stimulating factor subcutaneous injection followed by 8 mg of dexamethasone tablet 10–12 h and omnacortil 60 mg orally 3 h before harvest. A number of adverse incidents, if any, were observed and noted. Donor/procedure parameters were compared using Mann–Whitney U-test/unpaired t-test.

RESULTS:
Granulocyte yield (mean: 3.29 × 1010/unit vs. 4.5 × 1010/unit in the ACD and HES groups, respectively, P ≤ 0.0001) was significantly better in the HES group. The collection efficiency was also better in the HES group (mean: 15.86% vs. 26.70% in the ACD and HES groups, respectively, P ≤ 0.0001) in the ACD and HES groups, respectively. There was no significant adverse event noted in any of these two groups.

CONCLUSION:
In our study, granulocytes with optimum yield can be easily harvested with Spectra Optia cell separator using 6% HES (MMW) and trisodium citrate combination with standard 12-h interval gap between mobilization and harvest. This strategy can also have no or minimal extra cost burden to patients.
Locally Advanced Breast Cancer Patient’s Recurrence Rates Comparison Received Steroidal and Nonsteroidal Aromatase Inhibitor Based on Luminal

Published: June 2024

ABSTRACT

Introduction:
Aromatase inhibitors are hormonal therapies used in menopausal breast cancer with positive progesterone receptors and/or estrogen receptors. A third-generation aromatase inhibitor is divided into two categories: reversible nonsteroids and irreversible steroids. According to the previous studies, there are no consistent research findings on the recurrence after aromatase inhibitor therapy in luminal-type locally advanced breast cancer (LABC).

Methods:
This study is an analytical observational study with a retrospective cohort design. The data taken are secondary data from medical records on patient visits with luminal-type LABC in the oncology clinic in 2018–2021. The statistical test was the Chi-square test to determine the relationship between age, luminal subtype, radiotherapy, steroid and nonsteroid aromatase inhibitors, and the recurrence rate.

Results:
It was found that 30% of luminal B patients who received steroidal aromatase inhibitor and 68.43% who received nonsteroidal aromatase inhibitor experienced recurrence, with an odds ratio (OR) of 5.056 (1.560–16.384; P = 0.012). Meanwhile, in luminal A patients, 17.2% of patients who received steroidal aromatase inhibitor and 68.2% who received nonsteroidal aromatase inhibitor experienced recurrence, with an OR of 10.286 (2.757–38.370; P = 0.000). Based on multivariate analysis, the luminal type had no significant impact on the increased risk of recurrence (P = 0.141), but the administration of aromatase inhibitor had a significant impact (P = 0.000).

Conclusion:
Luminal A LABC patients who received nonsteroidal aromatase inhibitors had a 10.286-fold higher risk of recurrence compared to those who received steroidal aromatase inhibitors.
Trends and Patterns of Top Ten Common Cancers in Eastern India from 2014 to 2021: A Retrospective Hospital-based Cancer Registry Data Update
Authors: Raj Shraddha , Sinha Dinesh K. , Madhawi Richa , Devi Seema , Kishor Kunal , Singh Rajesh K. , Prakash Aman 
Published: June 2024

Background:
India is a vast and diverse country with existing variations in the frequency and distribution of cancers across its various parts. In regions lacking population-based cancer registries (PBCRs) in a vast country like India, hospital-based cancer registry (HBCR) data become an important source of information on the trends and patterns of a region. To determine the numerical trends of cases of the top ten cancer sites reporting to HBCR of a tertiary care cancer center in Bihar from 2014 to 2021.

Materials and Methods:
The details of all histopathologically confirmed cancer cases registered in the HBCR department of radiation oncology, State Cancer Institute, Indira Gandhi Institute of Medical Sciences, Patna, India between January 2014 and December 2021 were included in this retrospective observational study. All these cases were grouped site-wise and listed in descending order of the total number of cases reported in each group. Cross-tabulation with age and sex distribution was done. The frequency distribution of the top ten leading cancers for every consecutive calendar year was plotted in line diagrams for time trend analysis. Statistical Package for the Social Sciences (IBM SPSS Statistics for Windows, Version 20.0. Armonk, NY: IBM Corp.). was used for analysis. Annual percent change (APC) was determined for the number of cases of all ten cancer sites using joinpoint regression analysis (Joinpoint Regression Software, Version 4.0.4—May 2013; Statistical Methodology and Applications Branch, Surveillance Research Program of the US National Cancer Institute; Bethesda, MD, USA).

Results:
Out of 32,057 total cancer cases registered between Jan 2014 and Dec 2021, 21,848 patients (68.2%) cases constituted the top ten cancers. The top ten cancers among both sexes were cancer gallbladder (n = 4204, 13.1%), head and neck (n = 3395, 10.6%), breast (n = 3392, 10.6%), lung (n = 2069, 6.5%), cervix (n = 2039, 6.4%), hematolymphoid (n = 1930, 6.0%), liver (n = 1572, 4.9%), stomach (n = 1116, 3.5%), ovary (n = 1103, 3.4%), and colon-rectum (n = 1028, 3.2%). Except for cervical and hematolymphoid cancers, the rest all showed a rising trend over consecutive years.

Conclusion:
Cancer of the gallbladder continues to be among the most common cancers in the region. Focused research in all aspects of this deadly disease is needed. Strengthening of prevention and screening programs for common cancers and upliftment of the existing infrastructure for diagnosis and treatment of cancer in the region are necessitated.
Prevalence of Postoperative Morbidity in Patients Undergoing Elective Open Major Thoracoabdominal Oncosurgery and Their Correlation with Perioperative Management
Authors: Nandi Rudranil , Mishra Seema , Bhoriwal Sandeep , Maurya Prateek , Agrawal Kritika 
Published: June 2024

Background and Aims:
Due to rapidly advancing surgical techniques and perioperative management, more patients with comorbidities and poor physical condition are considered for surgical treatment for thoracoabdominal cancers, leading to an increased incidence of postoperative morbidity. We evaluated postoperative morbidity’s prevalence, types and risk factors after thoracoabdominal oncosurgery.

Methods:
Patients scheduled for elective major thoracoabdominal oncosurgery with an expected duration of more than 2 h and/or predicted blood loss of more than 500 mL were included. On the 3rd and 5th postoperative days (PODs), a postoperative morbidity survey (POMS) was administered by questioning the patients and their caregivers, examining the patients and reviewing patients’ charts, investigations and other records.

Results:
A total of 323 patients were enroled in the study. POMS-defined morbidity was present in 60.4% of patients on POD 3 and 18.9% of patients on POD 5. The most common morbidity on POD 3 was pain (34.8%), followed by gastrointestinal (GI) (24.2%) and pulmonary (14.3%) complications. On POD 5, the three most common complications were GI (7.8%), pulmonary (6.2%) and pain (5.9%). In multivariate analysis, female gender, hypertension, duration of surgery, intraoperative urine output and delayed extubation were found as independent predictors of POMS-defined morbidity on POD 3. However, on POD 5, multivariate analyses showed that intraoperative inotrope requirement, delayed extubation and intensive care unit stay were independent predictors of POMS-defined morbidity.

Conclusion:
Postoperative morbidity was present in 60.4% and 18.9% of patients on the 3rd and 5th PODs, respectively, after major thoracoabdominal oncosurgery. Pain and GI complications were the most common morbidity on the 3rd and 5th PODs, respectively.
