Kinetic Simulations of Nonrelativistic High-mach-number Perpendicular Shocks Propagating in a Turbulent Medium
Authors: Fulat Karol , Bohdan Artem , Torralba Paz Gabriel , Pohl Martin 
Published: December 2023

Abstract
Strong nonrelativistic shocks are known to accelerate particles up to relativistic energies. However, for diffusive shock acceleration, electrons must have a highly suprathermal energy, implying the need for very efficient preacceleration. Most published studies consider shocks propagating through homogeneous plasma, which is an unrealistic assumption for astrophysical environments. Using 2D3V particle-in-cell simulations, we investigate electron acceleration and heating processes at nonrelativistic high-Mach-number shocks in electron-ion plasma with a turbulent upstream medium. For this purpose, slabs of plasma with compressive turbulence are simulated separately and then inserted into shock simulations, which require matching of the plasma slabs at the interface. Using a novel procedure of matching electromagnetic fields and currents, we perform simulations of perpendicular shocks setting different intensities of density fluctuations (≲10%) in the upstream region. The new simulation technique provides a framework for studying shocks propagating in turbulent media. We explore the impact of the fluctuations on electron heating, the dynamics of upstream electrons, and the driving of plasma instabilities. Our results indicate that while the presence of turbulence enhances variations in the upstream magnetic field, their levels remain too low to significantly influence the behavior of electrons at perpendicular shocks.

Abstract
Black-hole-driven outflows in galaxies hosting active galactic nuclei (AGN) may interact with their interstellar medium (ISM) affecting star formation (SF). Such feedback processes, reminiscent of those seen in massive galaxies, have been reported recently in some dwarf galaxies. However, such studies have usually been on kiloparsec and larger scales and our knowledge of the smallest spatial scales to which these feedback processes can operate is unclear. Here we demonstrate radio jet−ISM interaction on the scale of an asymmetric triple radio structure of ∼10 pc size in NGC 4395. This triple radio structure is seen in the 15 GHz continuum image and the two asymmetric jet-like structures are situated on either side of the radio core that coincides with the optical Gaia position. The high-resolution radio image and the extended [O iii]λ5007 emission, indicative of an outflow, are spatially coincident and are consistent with the interpretation of a low-power radio jet interacting with the ISM. Modelling of the spectral lines using MAPPINGS, and estimation of temperature using optical integral field spectroscopic data suggest shock ionization of the gas. The continuum emission at 237 GHz, though weak, was found to spatially coincide with the AGN. However, the CO(2−1) line emission was found to be displaced by around 20 pc northward of the AGN core. The spatial coincidence of molecular H2
λ2.4085 along the jet direction, the morphology of ionized [O iii]λ5007, and displacement of the CO(2−1) emission argues for conditions less favorable for SF in the central ∼10 pc region.

Abstract
We present an analysis of new and archival data to the 20.506 minute LISA verification binary J052610.42+593445.32 (J0526+5934). Our joint spectroscopic and photometric analysis finds that the binary contains an unseen M
1 = 0.89 ± 0.11 M
⊙ CO-core white dwarf primary with an M
2 = 0.38 ± 0.07 M
⊙ post-core-burning subdwarf, or low-mass white dwarf, companion. Given the short orbital period and relatively large total binary mass, we find that LISA will detect this binary with signal-to-noise ratio 44 after 4 yr of observations. J0526+5934 is expected to merge within 1.8 ± 0.3 Myr and likely result in a D6 scenario Type Ia supernova or form a He-rich star that will evolve into a massive single white dwarf.
Contre la « saine famille »
Authors: Hadjadj Fabrice 
Published: December 2023

Il est probable que ce soit à partir des obscurs « liens du sang » que puisse naître l’amour le plus universel et le plus concret. Il s’agit précisément d’aimer ceux qu’on n’a pas choisis, ceux qu’on n’adopterait peut-être pas. C’est pourquoi les parents adoptifs conçoivent leur adoption sur le modèle de la parenté naturelle, et non sur celui d’un libre choix sur le marché des orphelins. C’est pourquoi, aussi, la charité trouve son analogie première dans les amours familiales les plus charnelles.
Somalie année zéro

Published: December 2023

Après vingt-deux ans de guerre civile, la Somalie, « État failli », est redevenue un État internationalement reconnu même si elle reste un « État fragile ». Le processus de retour à une certaine normalité comporte des enseignements pour d’autres cas, par exemple celui du Mali aujourd’hui. La période de transition a pris officiellement fin le 20 août 2012. De quelle transition parle-t-on ? De quoi vers quoi ? Et comment ?
L'Église romaine face à son avenir
Authors: Chiron Jean-François 
Published: December 2023

L’écho médiatique de la renonciation de Benoît XVI et de l’élection de son successeur François a pu surprendre par son ampleur. S’agit-il de l’intérêt manifesté à « la plus ancienne institution d’Occident » et à son représentant ou, plus profondément, de la fascination suscitée par une altérité ? Des interrogations s’expriment : le prochain pape fera-t-il évoluer l’Église ? Sera-t-il davantage en phase avec la modernité ?

La première réforme, le style chrétien
Authors: François Pape , Euvé François , Nicq Hervé 
Published: December 2023

Le risque de chercher et trouver Dieu en toutes choses est la volonté de trop expliciter, de dire avec certitude humaine et arrogance : « Dieu est ici. » Nous trouverons seulement un dieu à notre mesure. L’attitude correcte est celle de saint Augustin : chercher Dieu pour le trouver et le trouver pour le chercher toujours. Si le chrétien est légaliste ou cherche la restauration, s’il veut que tout soit clair et sûr, alors il ne trouvera rien.
La guerre de demain sera-t-elle juste ? Soldat augmenté et éthique de la guerre
Authors: Bourgois Pierre 
Published: December 2023

Quels sont les enjeux éthiques de l’augmentation militaire ? Plus particulièrement, quel est l’impact du phénomène sur la doctrine de la guerre juste ? Cet article fait le choix d’aborder la thématique du soldat augmenté sous l’angle spécifique de l’éthique de la guerre. Il s’agira, ainsi, de s’interroger sur ses possibles conséquences pour le jus ad bellum (entrée dans le conflit), le jus in bello (conduite du conflit) ainsi que le jus post bellum (après le conflit). Pour cela, les avantages comme les dangers représentés par le super soldat doivent être mis en lumière au niveau de ces trois dimensions. Le propos vise, par conséquent, à présenter une vue d’ensemble et équilibrée des potentiels effets du soldat augmenté à ce sujet, condition fondamentale pour une décision la plus éclairée possible concernant son encadrement nécessaire.
Hume et l'utilité
Authors: Cléro Jean-Pierre 
Published: December 2023

Hume est-il utilitariste ? Bentham n'a pas hésité à lui faire une place de choix dans ses deux articles sur l'utilitarisme. Mais, s'il est utilitariste, il l'est surtout dans l'Enquête sur les principes de la morale, qui fait suite au Traité de la nature humaine ; et il n'entend certainement pas l'utilité comme un utilitariste de la fin du siècle. L'utilitarisme de l'auteur n'est pas de la sorte qui se puisse calculer ; Hume n'est pas philosophe à laisser réduire toutes les valeurs à une seule, à la différence de ce qui se passera dans l'utilitarisme classique. Quant à l'aspect "senti" de l'utilité, il est constamment plus marqué chez Hume que chez Bentham, qui met plutôt l'accent sur le caractère structurant du langage. Toutefois, si la différence est profonde et modale, de Hume à Bentham, elle permet très facilement d'éclairer l'une des philosophies par l'autre, le commun dénominateur étant assuré par le commun signifiant de l'utile.

Published: December 2023

El análisis estadístico del resultado de los levantamientos realizados con láser escáner terrestre (TLS) en la catedral gótica meridional de Tortosa (1383), ha permitido demostrar que el trazado metrológico de su ábside tetradecagonal tiene una precisión metodológica del [± 1,502%]. Analíticamente, se determina que, dentro del rango de precisión, el ancho total de la girola es de 150 palmos, y que las capillas radiales tienen una dimensión de 24 palmos que son 3 canas, proporción tonal (9:8) respecto a la medida de la nave lateral de 27 palmos. La clave se sitúa a 100 palmos, y su sección final dispone de una relación (3:2) entre el ancho del deambulatorio de 150 palmos y su altura. Como conclusión, se observa una conjunción proporcional entre el orden medieval y la fábrica gótica. Las proporciones de la catedral de Tortosa forman parte de la tradición del Timeo, que bien conocían sus promotores, diferente a la de los maestros góticos septentrionales, con modelos de sección ad triangulum (1:√3/2) y ad quadratum (1:1) definidos en los debates de la catedral de Milán.
An Interesting Case of Takayasu’s Arteritis
Authors: Tadakal Vishwaraj , Mangane Arun D. 
Published: December 2023

Abstract
Takayasu’s arteritis is an inflammatory and stenotic disease of medium- and large-sized arteries characterized by a strong predilection for the aortic arch and its branches. Takayasu’s arteritis is an uncommon disease with an estimated annual incidence rate of 1.2–2.6 cases per million. It is most prevalent in adolescent girls and young women. Although it is more common in Asia, it is neither racially nor geographically restricted. This is a case report of a 58-year-old male patient who presented with syncopal attack and weakness in the right lower limb. He had a history of cerebrovascular accident (CVA) 10 years back with right upper limb monoparesis. Patient had feeble pulses in bilateral upper limb and absent pulsations in the right lower limb and left lower limb. Carotid pulsations were absent on the left side. Upper limb Doppler showed dampened and monophasic flow in ulnar and radial artery on both upper limbs. Dampened and monophasic flow in the right leg arterial system and posterior tibial artery of the left lower limb.
Recurrent Postpartum Hemorrhage: A Case of Uterine Artery Pseudoaneurysm Probably Induced by Anticoagulants
Authors: Jha* Sangam , Jha Sharda , Praveena Pammy , Brightsingh Jafeesha 
Published: December 2023

Abstract
Pseudoaneurysm formation often occurs when there is inadequate sealing at an arterial puncture site. We present the case of a 27-year-old primigravida with rheumatic heart disease and a history of mitral valve replacement on anticoagulants who experienced recurrent episodes of postpartum hemorrhage (PPH). Despite conservative management and adjustments to anticoagulant therapy, the bleeding persisted. Further investigations revealed a small pseudoaneurysm originating from the left uterine artery. Bilateral uterine artery embolization (UAE) using polyvinyl alcohol particles was successfully performed. The patient’s condition improved, and she was discharged on a carefully regulated medication regimen. This case highlights the importance of considering rare causes of PPH in high-risk patients, such as uterine artery pseudoaneurysm. Anticoagulants could be a potential contributor of its spontaneous rupture. Prompt diagnosis and appropriate intervention, such as UAE, can effectively manage PPH and prevent adverse outcomes.
Efficacy and safety of apatinib for elderly patients with previously treated extensive-stage colorectal cancer patients and the prognostic significance of common adverse reactions
Authors: Yu Yongjun , Li Yuwei , Xu Chen , Zhang Weihua 
Published: December 2023

Background:
This study was designed to investigate the efficacy and safety of apatinib monotherapy in the treatment of elderly patients with advanced colorectal cancer (CRC) who have progressed on the standard regimens.

Methods:
The data of 106 elderly patients with advanced CRC who have progressed on standard treatment were analyzed. The primary endpoint of this study was progression-free survival (PFS), the secondary endpoints were objective response rate (ORR), disease control rate (DCR), and overall survival (OS). The safety outcomes were assessed by the proportion and severity of adverse events.

Results:
Efficacy was assessed using the best overall response of patients during treatment with apatinib, including 0 patients with complete response, 9 patients with partial response, 68 patients with stable disease, and 29 patients with progressive disease. ORR and DCR were 8.5 and 72.6%, respectively. The median PFS of 106 patients was 3.6 months, and the median OS was 10.1 months. The most frequent adverse reactions of elderly patients with advanced CRC receiving apatinib treatment were hypertension (59.4%) and hand–foot syndrome (HFS) (48.1%). The median PFS of patients with and without hypertension was 5.0 and 3.0 months, respectively (P = 0.008). The median PFS of patients with and without HFS was 5.4 and 3.0 months, respectively (P = 0.013).

Conclusions:
The clinical benefit of apatinib monotherapy was observed in elderly patients with advanced CRC who have progressed on the standard regimens. The adverse reactions of hypertension and HFS were positively related to treatment efficacy.

Authors: Ratnakaran Nirosha , Nair Indu R , Rajanbabu Anupama , Patel Viral , Ariyannur Prasanth S , Kamalasanan Sukrishna 
Published: December 2023

Background:
The integration of molecular features into the already existing pathological classification of endometrial carcinomas will offer significant prognostic information. As the literature search reveals, there are no studies from India that have classified these carcinomas based on molecular subtypes. The aim of the study was to classify endometrial carcinomas into four subtypes based on their molecular and immunohistochemical features and to find out the association of each of these molecular subtypes with the other pathological parameters.

Methods:
A prospective study was done on 37 consecutive cases of fresh hysterectomy specimens, biopsy-proven as endometrial carcinomas between November 2019 and August 2020. Three immunohistochemical markers (p53, mismatch repair proteins, MutS homolog6 and Postmeiotic seggregation 2 respectively[MSH6, and PMS2]), along with DNA (deoxyribonucleic acid) sequencing of selected regions of the POLE gene was performed in each of the 37 cases. Endometrial carcinomas were subclassified into four subtypes, and the association of each of these four subtypes with the other pathological parameters was also explored. Statistical analysis was done using the IBM Statistical Package for the Social Science (SPSS) Version 20.0 software (IBM SPSS, USA).

Results:
Among the 37 cases studied, eight (21.6%) cases were p53 abnormal, eight (21.6%) cases showed MMR-D (mismatch repair deficient), one case (2.7%) showed mutation of POLE, and 21 cases (56.8%) were assembled under p53 wild-type. Higher grade endometrial carcinomas showed more (80.0%) p53 abnormal (P < 0.001). All the p53 wild-type (100%) were of Type 1 endometrial carcinoma subtype (P = 0.001) and low-grade type (90.5%; P = 0.005).

Conclusion:
Our study confirms that the type of carcinoma and grade correlates with p53 expression, p53 abnormal being associated with higher grade and type 2 endometrial carcinomas, whereas p53 wild-type is associated with low-grade and type 1 endometrial carcinoma. There was only one case of the POLE subtype identifiable in our study.
Neo-carina after carina resection and right upper lobectomy in a patient with adenoid cystic carcinoma: Alternative technique
Authors: Beyoglu Muhammet A. , Sahin Mehmet F. , Yazicioglu Alkin , Yekeler Erdal 
Published: December 2023

Abstract
Surgical treatment of carinal tumors that extend into the lobar bronchus is a procedure that challenges thoracic surgeons. There is no consensus on the suitable technique for a safe anastomosis in lobar lung resection with carina. The preferred Barclay technique has a high rate of anastomosis-related complications. Although a lobe-sparing end-to-end anastomosis technique has been previously described, the double-barrel method can be applied as an alternative technique. We present a case where we performed double-barrel anastomosis and neo-carina formation after tracheal sleeve right upper lobectomy.

Published: December 2023

Abstract

Background:
There is no doubt about the oncologic effectiveness of neck dissections (NDs). But the quality of life (QoL) of patients with oral cancer and the morbidity associated with ND like shoulder dysfunction remain uncertain. The present study aimed to assess the postoperative ND-related QoL and shoulder function of oral cancer patients who underwent selective neck dissection (SND).

Methods:
A cross-sectional study was conducted by using a self-administered, ND-related QoL questionnaire and arm abduction test (AAT) in 128 patients who had undergone only SND (up to Level IV) for oral cancer.

Results:
Out of the 128 patients, 94 (73.8%) patients had better QoL, and 34 (26.2%) patients had worse QoL. Fifty-one (39.84%) participants were able to abduct up to or more than 150° but less than 180° (Score 3) followed by 31 (24.22%) participants who could abduct up to or more than 90° but not less than 150° (Score 2). Strong positive correlations (r = 1.000) were observed between the ND QoL scores and the AAT scores. It was found to be statistically significant (P = 0.000).

Conclusion:
SND, being a more conservative approach sparing the spinal accessory nerve, could still limit the QoL and could affect the shoulder function to a certain extent.

Equal-Sum-Product problem II

Published: December 2023

AbstractIn this paper, we present the results related to a problem posed by Andrzej Schinzel. Does the number
$N_1(n)$
of integer solutions of the equation
$$ \begin{align*}x_1+x_2+\cdots+x_n=x_1x_2\cdot\ldots\cdot x_n,\,\,x_1\ge x_2\ge\cdots\ge x_n\ge 1\end{align*} $$
tend to infinity with n? Let a be a positive integer. We give a lower bound on the number of integer solutions,
$N_a(n)$
, to the equation
$$ \begin{align*}x_1+x_2+\cdots+x_n=ax_1x_2\cdot\ldots\cdot x_n,\,\, x_1\ge x_2\ge\cdots\ge x_n\ge 1.\end{align*} $$
We show that if
$N_2(n)=1$
, then the number
$2n-3$
is prime. The average behavior of
$N_2(n)$
is studied. We prove that the set
$\{n:N_2(n)\le k,\,n\ge 2\}$
has zero natural density.
