X-Ray Spectroscopy of the Dwarf Nova Z Chamaeleontis in Quiescence and Outburst Using the XMM-Newton Observatory
Authors: Balman Şölen , Schlegel Eric M. , Godon Patrick , Drake Jeremy J. 
Published: December 2024

Abstract
We present X-ray spectroscopy of the SU UMa–type dwarf nova Z Chamaeleontis using the European Photon Imaging Camera and reflection grating spectrometer (RGS) instruments on board the XMM-Newton observatory. The quiescent system can be modeled by collisional equilibrium (CIE) or nonequilibrium plasma models, yielding a kT of 8.2–13.0 keV at a luminosity of (5.0–6.0) × 1030 erg s−1. The spectra yield better

using partially covering absorbers of cold and/or photoionized nature. The ionized absorber has an equivalent N
H = (3.4–5.9) × 1022 cm−2 and a log(ξ) = 3.5–3.7 with a (50–60)% covering fraction when the VNEI model (XSPEC) is used. The line diagnosis in quiescence shows no resonance lines, with only the forbidden lines of Ne, Mg, and Si detected. The H-like C, O, Ne, and Mg are detected. The strongest line is O viii, with (2.7–4.6) × 10−14 erg s−1 cm−2. The quiescent X-ray-emitting plasma is not collisional and not in ionization equilibrium, which is consistent with hot ADAF-like accretion flows. The line diagnosis in the outburst shows He-like O and Ne, with intercombination lines being the strongest, along with weaker resonance lines. This indicates the plasma is more collisional and denser, but not yet in CIE, revealing ionization timescales of (0.97–1.4) × 1011 s cm−3. The R ratios in the outburst yield electron densities of (7–90) × 1011 cm−3 and the G ratios yield electron temperatures of (2–3) × 106 K. The outburst luminosity is (1.4–2.5) × 1030 erg s−1. The flow is inhomogeneous in density. All detected lines are narrow, with widths limited by the resolution of RGS, yielding Keplerian rotational velocities <1000 km s−1. This is too low for boundary layers, consistent with the nature of ADAF-like hot flows.

Published: December 2024

Abstract
Fast radio bursts (FRBs) are bright radio transients with millisecond durations, which typically occur at extragalactic distances. The association of FRB 20200428 with the Galactic magnetar SGR J1935+2154 strongly indicates that they could originate from neutron stars, which naturally leads to the expectation that periodicity connected with the spinning of magnetars should exist in the activities of repeating FRBs. However, previous studies have failed to find any signatures supporting such a conjecture. Here we perform a thorough search for short-timescale periodicity in the four most active repeating sources, i.e., FRBs 20121102A, 20200120E, 20201124A, and 20220912A. Three different methods are employed, including a phase folding algorithm, the H-test, and Lomb–Scargle periodograms. For the three most active repeaters from which more than 1000 bursts have been detected, i.e., FRBs 20121102A, 20201124A, and 20220912A, more in-depth period searches are conducted by considering various burst properties such as the pulse width, peak flux, fluence, and the brightness temperature. No clear periodicity is found in a period range of 0.001–1000 s in all efforts. Implications of such a null result on the theoretical models of FRBs are discussed.

Published: December 2024

Abstract
The Faraday rotation effect, quantified by the rotation measure (RM), is a powerful probe of the large-scale magnetization of the Universe—tracing magnetic fields not only on galaxy and galaxy cluster scales but also in the intergalactic medium (IGM; referred to as RMIGM). The redshift dependence of the latter has extensively been explored with observations. It has also been shown that this relation can help to distinguish between different large-scale magnetization scenarios. We study the evolution of this RMIGM for different primordial magnetogenesis scenarios to search for the imprints of primordial magnetic fields (PMFs; magnetic fields originating in the early Universe) on the redshift-dependence of RMIGM. We use cosmological magnetohydrodynamic simulations for evolving PMFs during large-scale structure formation, coupled with the light-cone analysis to produce a realistic statistical sample of mock RMIGM images. We study the predicted behavior for the cosmic evolution of RMIGM for different correlation lengths of PMFs, and provide fitting functions for their dependence on redshifts. We compare these mock RM trends with the recent analysis of the the LOw-Frequency ARray RM Grid and find that large-scale-correlated PMFs should have (comoving) strengths ≲0.75 nG, if they originated during inflation with the scale-invariant spectrum and (comoving) correlation length of ∼19 h
−1 cMpc or ≲30 nG if they originated during phase-transition epochs with the comoving correlation length of ∼1 h
−1 cMpc. Our findings agree with previous observations and confirm the results of semi-analytical studies, showing that upper limits on the PMF strength decrease as their coherence scales increase.
The Foundations of Multi-line Molecular Cloud Population Synthesis
Authors: Perry Marissa N. , Sheen Derek , Kauffmann Jens 
Published: December 2024

Abstract
While galactic molecular clouds have been studied in great detail, the spatial resolution of current single-dish radio telescopes inhibits our ability to resolve individual molecular clouds in external galaxies. In this case, the line luminosity signal received is an average over a ≥100 pc diameter beam containing several molecular clouds. This leads us to an interesting question: If we point the telescope beam at a region of molecular clouds in a nearby galaxy, can we meaningfully decompose the unresolved signal we receive? In this work, we formulate theoretical methods of decomposing a galaxy line luminosity signal into its cloud population line luminosity components.
Stable Stratification of the Helium Rain Layer Yields Vastly Different Interiors and Magnetic Fields for Jupiter and Saturn
Authors: Markham S. , Guillot T. 
Published: December 2024

Abstract
At sufficiently high pressures (∼Mbar) and low temperatures (∼103–104 K), hydrogen and helium become partly immiscible. Interpretations of Jupiter’s and Saturn’s magnetic fields favor the existence of a statically stable layer near the Mbar pressure level. From experimental and computational data for the hydrogen–helium phase diagram, we find that moist convection and diffusive convection are inhibited, implying a stable helium rain layer in both Jupiter and Saturn. However, we find a significant difference in terms of structure and evolution: in Jupiter, helium settling leads to a stable yet superadiabatic temperature gradient that is limited by conductive heat transport. The phase separation region should extend only a few tens of kilometers, instead of thousands in current-day models, and be characterized by a sharp increase of the temperature of about 500 K for standard phase separation diagrams. In Saturn, helium rains occur much deeper, implying a larger helium flux relative to planetary mass. We find that the significant latent heat associated with helium condensation implies that a large fraction, perhaps close to 100%, of the planet’s intrinsic heat flux may be locally transported by the sinking helium droplets. This implies that Saturn may possess a much more extended helium rain region. This also accounts, at least qualitatively, for the differences in strength and characteristics of the magnetic fields of the two planets. Dedicated models of magnetic field generation in both planets may offer observational constraints to further refine these findings.
Phase Equilibria of Sub-Neptunes and Super-Earths

Published: December 2024

Abstract
We investigate the consequences of nonideal chemical interaction between silicate and overlying hydrogen-rich envelopes for rocky planets using basic tenets of phase equilibria. Based on our current understanding of the temperature and pressure conditions for complete miscibility of silicate and hydrogen, we find that the silicate-hydrogen binary solvus will dictate the nature of atmospheres and internal layering in rocky planets that garnered H2-rich primary atmospheres. The temperatures at the surfaces of supercritical magma oceans will correspond to the silicate-hydrogen solvus. As a result, the radial positions of supercritical magma ocean–atmosphere interfaces, rather than their temperatures and pressures, should reflect the thermal states of these planets. The conditions prescribed by the solvus influence the structure of the atmosphere, and thus the transit radii of sub-Neptunes. Separation of iron-rich metal to form metal cores in sub-Neptunes and super-Earths is not assured due to prospects for neutral buoyancy of metal in silicate melt induced by dissolution of H, Si, and O in the metal at high temperatures.
Trophic Transfer of Fipronil Residues to Black-footed Ferrets: Implications for Flea Control and Plague Mitigation

Published: December 2024

Abstract
Sylvatic plague, caused by the flea-borne bacterium Yersinia pestis, is an invasive disease in North America that causes reductions of native fauna and transforms ecosystems. Fipronil baits have shown promise in reducing flea loads on prairie dogs Cynomys spp. for plague mitigation. Many species depend on prairie dogs and their ecological influences, including the black-footed ferret Mustela nigripes (ferret), an obligate predator of prairie dogs. To better understand how fipronil affects ferrets, we offered carcass portions from black-tailed prairie dogs C. ludovicianus that had consumed fipronil bait (0.005% fipronil by weight) to captive ferrets and monitored their health. We fed carcass portions of three prairie dogs to four adult ferrets for 1 week. No ill effects were observed in the ferrets. We collected scat from the ferrets before, during, and after their feeding on treated prairie dogs. We evaluated potential effects of ferret scat on larval fleas, which feed on organic matter. Fipronil residues were not detected in ferret scat samples collected before treatment. During and shortly after treatment, ferret scat contained 3.76 ng/g fipronil and 13.75 ng/g fipronil sulfone, on average, demonstrating trophic transfer of the residues from prey to predator. We presented 0.5 mg of ferret scat to each of 96 larval Oropsylla montana (Siphonaptera: Ceratophyllidae) and assessed survival rates over 24 h. When exposed to ferret scat lacking fipronil residues, 85% of larvae survived. Survival was reduced to 61% and 35% for larvae contacting or consuming scat with fipronil residue, respectively. Fipronil residues in scat from a variety of species on prairie dog colonies, perhaps especially the prairie dogs, may assist in flea control and plague mitigation. Hosts eliminate fipronil residues, and fipronil residues in the environment degrade over time, reducing but not eliminating potential concerns with bioaccumulation.
La bibliothèque fantastique de Sylvie Germain
Authors: Demanze Laurent 
Published: December 2024

La bibliothèque de Sylvie Germain est hantée. Mais ces fantômes et ces présences spectrales s’écartent de la tradition fantastique du XIXe siècle. Ils sont davantage la conséquence d’un fantastique de bibliothèque, analysé par Michel Foucault, qui considérait l’expérience littéraire comme une activité aux marges de la raison.
Hors champ : fiction critique, critique-fiction
Authors: Michelet Jacquod Valérie 
Published: December 2024

Les romans de Sylvie Germain, plus particulièrement depuis Magnus, se rapprochent des fictions critiques décrites par Dominique Viart. Situant leurs intrigues dans la société contemporaine, ils en présentent les tendances et les lois occultes, proposent une discussion sur l’historiographie tout en interrogeant les conditions d’une expérimentation du monde par la littérature à travers le statut de lecteur. Or ce statut, tel qu’il apparaît dans Hors champ, invite à passer de la fiction critique à la critique-fiction. Le hors-champ du texte devient alors celui de ses possibles, que l’inexpliqué aiguise.
Aoi Shiba no Kai: A Disability Rights Movement Fighting Against Eugenics
Authors: Mithout Anne-Lise 
Published: December 2024

Au début des années 1970, émerge pour la première fois au Japon un mouvement de personnes handicapées militant pour leur reconnaissance sociale et le respect de leurs droits humains. Ce mouvement, porté par l’association Aoi shiba no kai, naît de la critique de la relative tolérance pour les infanticides d’enfants handicapés et se fédère autour de la dénonciation de « l’eugénisme », un concept aux contours parfois flous, utilisé pour décrire un ensemble de situations très large. Cet article s’appuie sur les écrits de Yokozuka Kōichi, l’un des principaux leaders d’Aoi shiba no kai. Il vise à analyser comment, et avec quelles conséquences, Yokozuka Kōichi fait de la lutte contre « l’eugénisme » un instrument d’émancipation et d’affirmation de soi des personnes handicapées. On met ainsi en lumière le passage de la revendication d’un droit à l’existence des personnes handicapées à celle d’un droit à la reconnaissance du handicap en tant qu’identité particulière.

Authors: Baby Betsy , Pushpagiri Sandhya , Varma P Ravi Prasad , Saritha LS , Dhiya SJ , Meera Shoba S , Rekha M , Mohan Manju , Sundaram Soumya 
Published: December 2024

Background and Objectives:
Broad Autism Phenotype (BAP) refers to specific behaviors or minor deficits in social/communication skills not meeting the diagnostic criteria for autism spectrum disorders (ASDs). The BAP Questionnaire (BAPQ) measures aloof personality (AP), rigid personality (RP), and pragmatic language (PL) deficits of BAP. The study objective is to translate and validate BAPQ into Malayalam, a South Indian language, and to establish new cut-off scores for detecting BAP in the Indian population.

Methods:
BAPQ was translated into Malayalam (BAPQ-M), following which it was tested for reliability and internal consistency and factor analysis was conducted in 40 parents of ASD and neurotypical children. The receiver operating characteristic curve analysis generated new cut-off scores.

Results:
The content validity index was ≥ 0.8 for each item. For the self and informant versions, Cronbach’s α was 0.753 and 0.807, respectively, while Spearman’s correlation coefficient was 0.953 (P < 0.001) and 0.918 (P < 0.001). The items demonstrated good communality (0.532–0.870), and on factor rotation, 12 components had eigenvalues > 1, which explained 72.3% of the total variance. The new cut-off scores for total estimate, AP, RP, and PL subscales were 2.60 (sensitivity 0.825; specificity 0.575; odds ratio [OR] 6.38, 95% confidence interval [CI] 2.28–17.84; P < 0.001), 2.60 (sensitivity 0.60; specificity 0.75; OR 4.50, 95% CI 1.73–11.70; P 0.002), 2.90 (sensitivity 0.8; specificity 0.475; OR 3.62, 95% CI 1.342–9.77; P 0.011), and 2.70 (sensitivity 0.5; specificity 0.825; OR 4.71, 95% CI 1.69–13.13; P 0.003), respectively.

Conclusions:
BAPQ-M has good psychometric properties for determining the presence of BAP among the people of Kerala, a South Indian state.
Infinite dimensional sequential compactness: Sequential compactness based on barriers

Abstract
We introduce a generalization of sequential compactness using barriers on

$\omega $

extending naturally the notion introduced in [W. Kubiś and P. Szeptycki, On a topological Ramsey theorem, Canad. Math. Bull., 66 (2023), 156–165]. We improve results from [C. Corral and O. Guzmán and C. López-Callejas, High dimensional sequential compactness, Fund. Math.] by building spaces that are

${\mathcal {B}}$

-sequentially compact but not

${\mathcal {C}}$

-sequentially compact when the barriers

${\mathcal {B}}$

and

${\mathcal {C}}$

satisfy certain rank assumption which turns out to be equivalent to a Katětov-order assumption. Such examples are constructed under the assumption

${\mathfrak {b}} ={\mathfrak {c}}$

. We also exhibit some classes of spaces that are

${\mathcal {B}}$

-sequentially compact for every barrier

${\mathcal {B}}$

, including some classical classes of compact spaces from functional analysis, and as a byproduct, we obtain some results on angelic spaces. Finally, we introduce and compute some cardinal invariants naturally associated to barriers.
Reliability of a modified single-point rubric for assessment of integrated pharmacotherapy cases
Authors: Bowers Riley , Baker Carrie , Kelly Kimberly , Pulgar Victor , Raccor Brianne , Stockdale Myrah 
Published: December 2024

Background: The Pharmacists’ Patient Care Process (PPCP) offers a method to integrate pharmacotherapy cases between disciplines. However, establishing a consistent grading standard across multiple faculty and disciplines creates a challenge. The purpose of this study was to describe the reliability of a single-point rubric for assessing integrated cases among interdisciplinary graders.
Methods: A single-point rubric was developed to provide students with formative and summative feedback on existing integrated cases requiring written PPCP notes. The rubric was calibrated retrospectively on a sample of deidentified cases from two integrated pharmacotherapy courses. Following calibration, 20 submissions were evaluated by an interdisciplinary team of faculty. The following year, four new evaluators graded 12 submissions to ensure continued reliability.
Results: Fleiss' kappa was used to determine if there was an agreement between instructors’ judgement on the final grade classification of the original 20 submissions. There was almost perfect agreement between the instructors’ judgements, κ= .868. Each section of the PPCP and overall numerical score all showed significant agreement using Kendall’s W. Results were similar the following year with four new graders.
Conclusion: This study demonstrates the continued reliability of a modified single-point rubric to evaluate written cases involving multiple disciplines.
Русская эмиграция во Франции и Католическая Церковь в межвоенный период
Authors: Д.М. Титов 
Published: December 2024

Данная статья посвящена тому, как складывались взаимоотношения русской эмигрантской диаспоры первой волны во Франции и православного духовенства с одной стороны и Католической Церкви с аффилированными с ней французскими организациями с другой в период между двумя мировыми войнами. Революционные события в России привели к массовому исходу подданых Российской Империи, десятки тысяч русских эмигрантов, исповедовавших православную веру, выбрали католическую Францию своим новым домом. Русская эмиграция и французское общество, православие и католичество, должны были найти способ сосуществования. В данной статье рассматриваются благотворительная, миссионерская и культурная деятельность Папского престола и французских католических организаций по отношению к русским эмигрантам и духовенству, а также взаимные попытки установить межконфессиональный диалог. Для раскрытия данной темы необходимо затронуть вопросы: мотивации определявшую политику Ватикана в «Русском вопросе», взаимного восприятия католиков и православных и описать контекст существования русской диаспоры во Франции в период интербеллума.
This article is devoted to the development of relations between the first wave of Russian émigré diaspora in France and the Orthodox clergy on the one hand, and the Catholic Church with its affiliated French organizations on the other, in the period between the two world wars. The revolutionary events in Russia led to a mass exodus of subjects of the Russian Empire; tens of thousands of Russian émigrés who professed the Orthodox faith chose Catholic France as their new home. Russian émigrés and French society, Orthodoxy and Catholicism, had to find a way to coexist. This article examines the charitable, missionary, and cultural activities of the Holy See and French Catholic organizations in relation to Russian émigrés and the clergy, as well as mutual attempts to establish interfaith dialogue. To reveal this topic, it is necessary to touch upon the following issues: the motivations that determined the Vatican’s policy in the “Russian question”, the mutual perception of the Catholics and the Orthodox, and to describe the context of Russian diaspora’s existence in France during the interbellum.
Генезис идеи корпоративной личности Христа и ее рецепция в богословии митрополита Иоанна (Зизиуласа)
Authors: А.С. Ильин 
Published: December 2024

В статье автор анализирует происхождение понятия корпоративной личности. Концепция корпоративной личности возникает в среде протестантских богословов в первой половине XX в. как способ осмысления проблемы вины и божественного оправдания в контексте юридической теории искупления. Впоследствии концепция корпоративной личности входит в научный оборот с более широкой дефиницией. В православном богословии идеи корпоративной личности активно использовал митрополит Иоанн (Зизиулас) для своей реляционной теологии. В отечественной научной литературе феномен корпоративной личности в богословии практически не исследован, в связи с чем целью настоящей работы является попытка проследить появление идеи о корпоративной личности Христа в протестантской теологии и ее разработку в богословии митрополита Иоанна (Зизиуласа). Автор определяет положения этой идеи в системе богословия общения митрополита Иоанна и приходит к выводу, что в изложенном им варианте концепция корпоративной личности входит в противоречие с традиционной церковной онтологией и в практическом выражении становится богословским обоснованием идеи первенства Константинопольского патриархата в Православной Церкви.
In the presented article, the author analyzes the origin of the notion of corporate personality. The concept of corporate personality arose among Protestant theologians in the first half of the 20th century as a way of understanding the problem of guilt and divine justification in the context of legal theory of redemption. Subsequently, the concept of corporate identity enters scientific circulation with a broader definition. In Orthodox theology, Metropolitan John (Zizioulas) actively used the ideas of corporate personality for his relational theology. In the Russian scientific literature, the phenomenon of corporate personality in theology has not been practically studied, and therefore the purpose of this work is to try to trace the emergence of the idea of Christ’s corporate personality in Protestant theology and its development in the theology of Metropolitan John (Zizioulas). The author defines the provisions of this idea in Metropolitan John’s system of communion theology, and comes to the conclusion that in the version outlined by him, the concept of corporate personality contradicts traditional church ontology, and in practical terms becomes the theological justification of the idea of the primacy of the Patriarchate of Constantinople in the Orthodox Church.
