Published: January 2025

В статье рассматривается вероятностный подход при оценке воздействия механических вибраций на параметры волоконно-оптического кабеля, подвешенного на опорах контактной сети железных дорог. Показано, что игнорирование данного метода может привести к ухудшению качества передаваемой информации в высокоскоростных цифровых волоконно-оптических систем передачи.
The paper considers a probabilistic approach to assess the impact of mechanical vibrations on the parameters of fiber-optic cable suspended on the supports of the railroad contact network. It is shown that ignoring this method can lead to a sharp deterioration of the quality of transmitted information in high-speed digital fiber-optic transmission systems.

В статье приведены результаты исследования гинекологических патологии, наиболее распространенными среди которых были патологии матки до 50%, в том числе клинически выраженного эндометрита до 30%, субклинического эндометрта – до 13%, субинволюции матки – до 12%. После первого осеменения до 30-40-го дня после отёла, стельными оказались до 20,0% животных, что приблизительно в 2 раза ниже, чем в более поздние сроки.
До настоящего времени бесплоди причиняет большой экономический ущерб животноводству РК . Бесплодие — это лишь признак или следствие какого-либо состояния (в том числе болезни), в результате которого нарушается воспроизводство стад. Это нарушение воспроизводства маточного стада и ремонтного молодняка как результат воздействия стресс-факторов (алиментарного, климатического и др.), погрешностей в искусственном или естественном осеменении, болезней репродуктивных органов, иммунных реакций. Таким образом, бесплодной следует считать корову не осеменённую либо осеменённую, но не оплодотворившуюся в течение двух месяцев после отёла (или спустя 1 месяц после завершения физиологических сроков инволюции половых органов).
Восстановительные процессы в матке протекали медленнее, но достигаемая за счёт овариостимуляции стабилизация функциональной деятельности яичников ускоряли восстановительные процессы в матке. В последующих работах мы поставили задачу провести акушерско-гинекологическую дипансеризацию маточного поголовья в послеродовом периоде и выявить наиболее распространеные патологий половых органов у коров и разработать эффективные методы лечения с целью восстановления функций половых органов, таким образом нами выявлены в данном хозяйстве до 30% бесплодных коров и основным видом бесплодия коров было симптоматическое бесплодие , что составляло 67% это такие патологий как – гнойно-катаральное восполение матки, патологии яичников и их функциональное нарушение, вагиниты, вестибуловагиниты, среди гинекологических патологий самым распространеным были гнойно-катаралбные эндометриты, поэтому мы решили применить для лечения этой патологии , опрабированные нами методы лечения и обследовать биохимические и гематологические покозателей сыворотки крови коров при гнойно-катаральном эндометрите до лечения и после лечения, все данные результатов биохимических и гематологических изменений в сыворотке крови коров обсуждены в этой статье и сделаны соответствующие выводы по ним.

Бүгінгі таңда Қазақстан аумағында ең маңызды проблемалардың бірі мал арасында паразиттік аурулардың көп болуы, атап айтқанда мониезиоздың таралуы болып табылады. Мақалада Алматы облысы аймағында қой мониезиозын зерттеу және қой шаруашылығында кездесетін гельминттердің түрлерін анықтау нәтижелері берілген. Зерттеу жұмыстары күзгі кезеңде жүргізілді және «Нұрай» жеке шаруашылығында 40 бас малдың нәжіс сынамалары зерттелінді. Сынамаларды Дарлинг, Фюллебон және Г.А. Котельников және В.М. Хренов әдістерімен Қазақ Ұлттық аграрлық зерттеу университетінің биологиялық қауіпсіздік кафедрасына қарасты зертханада балау әдістері қойылып, паразиттердің түрлік құрамы, инвазияның қарқындылығы (ИИ) және инвазияның экстенсивтілігі (ИЭ) және паразитоценоз түрлерінің құрамдас бөліктерін зерттедік.
Қойларда кездесетін паразитоздарды копрологиялық әдістермен зерттегенде, аноплоцефалаттар инвазиясы моноинвазиялар және аралас инвазиялар түрінде анықталған. Қойдың ішек-қарын жолында кездесетін паразитоздарды копрологиялық әдістермен зерттеген уақытта 4 гельминт кездесті: Dictyocaulus filarial, Moniezia expansa, Thysaniezia giardi және Avitellina centripunctata.
Айта кету керек, ауруға шалдыққан қойлардың диктиокаулезбен (Dictyocaulus filarial) жалпы залалдануы 12,5% (5 бас) құрады, бір көру аймағында инвазия қарқындылығы 1-ден 14 жұмыртқаға дейін залалданған, ал Moniezia expansa 40 қойдың 12 бас 30 % залалданған. Сондай-ақ Thysaniezia giardi 8 қой жұқтырды (ИЭ 20,0%, ИИ 1-2 жұмыртқа) және Avitellina centripunctata 2 қой (ИЭ 5,0%, ИИ 1). Осылайша, Moniezia expansa инвазиясының жоғары қарқындылығы байқалды. Инвазия интенсивтілігі жоғары, микроскоптың 1 көру алаңында 1-14 жұмыртқа. Инвазия интенсивтілігі төмен, микроскоптың 1 көру алаңында 1-6 жұмыртқа анықталды.

Abstract
A star's spin–orbit angle can give us insight into a system's formation and dynamical history. In this paper, we use MAROON-X observations of the Rossiter–McLaughlin effect to measure the projected obliquity of the LP 261-75 (also known as TOI-1779) system, focusing on the fully convective M dwarf LP 261-75A and the transiting brown dwarf LP 261-75C. This is the first obliquity constraint of a brown dwarf orbiting an M dwarf and the seventh obliquity constraint of a brown dwarf overall. We measure a projected obliquity of

degrees for the system, meaning that the system is well aligned and that the star is rotating very nearly edge-on, with an inclination of 90° ± 11°. The system thus follows along with the trends observed in transiting brown dwarfs around hotter stars, which typically have low obliquities. The tendency for brown dwarfs to be aligned may point to some enhanced obliquity damping in brown dwarf systems, but there is also a possibility that the LP 261-75 system was simply formed aligned. In addition, we note that the brown dwarf's radius (R

C
= 0.9 R
J) is not consistent with the youth of the system or radius trends observed in other brown dwarfs, indicating that LP 261-75C may have an unusual formation history.
The Effect of Galaxy Interactions on Starbursts in Milky Way-mass Galaxies in FIRE Simulations

Published: January 2025

Abstract
Simulations and observations suggest that galaxy interactions may enhance the star formation rate (SFR) in merging galaxies. One proposed mechanism is the torque exerted on the gas and stars in the larger galaxy by the smaller galaxy. We analyze the interaction torques and star formation activity on six galaxies from the FIRE-2 simulation suite with masses comparable to the Milky Way galaxy at redshift z = 0. We trace the halos from z = 3.6 to z = 0, calculating the torque exerted by the nearby galaxies on the gas in the central galaxy. We calculate the correlation between the torque and the SFR across the simulations for various mass ratios. For near-equal-stellar-mass-ratio interactions in the galaxy sample, occurring between z = 1.2−3.6, there is a positive and statistically significant correlation between the torque from nearby galaxies on the gas of the central galaxies and the SFR. For all other samples, no statistically significant correlation is found between the torque and the SFR. Our analysis shows that some, but not all, major interactions cause starbursts in the simulated Milky Way-mass galaxies, and that most starbursts are not caused by galaxy interactions. The transition from “bursty” at high redshift (z ≳ 1) to “steady” star formation state at later times is independent of the interaction history of the galaxies, and most of the interactions do not leave significant imprints on the overall trend of the star formation history of the galaxies.
On the Existence of Long-period Decayless Oscillations in Short Active Region Loops

Published: January 2025

Abstract
Decayless kink oscillations, characterized by their lack of decay in amplitude, have been detected in coronal loops of varying scales in active regions, the quiet Sun, and coronal holes. Short-period (<50 s) decayless oscillations have been detected in short loops (< 50 Mm) within active regions. Nevertheless, long-period decayless oscillations in these loops remain relatively unexplored and crucial for understanding the wave modes and excitation mechanisms of decayless oscillations. We present the statistical analysis of decayless oscillations from two active regions observed by the Extreme Ultraviolet Imager onboard Solar Orbiter. The average loop length and period of the detected oscillations are 19 Mm and 151 s, respectively. We find 82 long-period and 23 short-period oscillations in these loops. We do not obtain a significant correlation between loop length and period. We discuss the possibility of different wave modes in short loops, although standing waves cannot be excluded from possible wave modes. Furthermore, a different branch exists for active region short loops in the loop length versus period relation, similar to decayless waves in short loops in the quiet Sun and coronal holes. The magnetic fields derived from MHD seismology, based on standing kink modes, show lower values for multiple oscillations compared to previous estimates for long loops in active regions. Additionally, the comparison of period distributions in short loops across different coronal regions indicates that different excitation mechanisms may trigger short-period kink oscillations in active regions compared to the quiet Sun and coronal holes.
A uGMRT and MeerKAT Study of Radio Relics in the Low-mass Merging Cluster PSZ2 G200.95−28.16
Authors: Pal Arpan , Kale Ruta , Wang Qian H. S. , Wik Daniel R. 
Published: January 2025

Abstract
Diffuse radio sources known as radio relics are direct tracers of shocks in the outskirts of merging galaxy clusters. PSZ2 G200.95–28.16, a low-mass merging cluster (M
500 = (2.7 ± 0.2) × 1014
M
⊙), features a prominent radio relic, first identified by R. Kale et al. We name this relic as the Seahorse. The MeerKAT Galaxy Cluster Legacy Survey has confirmed two additional radio relics, R2 and R3, in this cluster. We present new observations of this cluster with the upgraded Giant Metrewave Radio Telescope (uGMRT) at 400 and 650 MHz, paired with Chandra X-ray data. The largest linear sizes for the three relics are 1.53 Mpc, 1.12 kpc, and 340 kpc. All three radio relics are polarized at 1283 MHz. Assuming the diffusive shock acceleration model, the spectral indices of the relics imply shock Mach Numbers of 3.1 ± 0.8 and 2.8 ± 0.9 for the Seahorse and R2, respectively. The Chandra X-ray surface brightness map shows two prominent subclusters, but the relics are not perpendicular to the likely merger axis, as typically observed; no shocks are detected at the locations of the relics. We discuss possible merger scenarios in light of the low mass of the cluster and the radio and X-ray properties of the relics. The relic R2 follows the correlation known in the radio relic power and cluster-mass plane, but the Seahorse and R3 relics are outliers. We have also discovered a radio ring in our 650 MHz uGMRT image that could be an Odd Radio Circle candidate.
The Blue Lurker WOCS 14020: A Long-period Post-common-envelope Binary in M67 Originating from a Merger in a Triple System

Abstract
We present Hubble Space Telescope far-ultraviolet (FUV) spectra of a blue lurker–white dwarf (BL–WD) binary system in the 4 Gyr open cluster M67. We fit the FUV spectrum of the WD, determining it is a C/O WD with a mass of

M
⊙ and a cooling age of ~400 Myr. This requires a WD progenitor of ~3 M
⊙, significantly larger than the current cluster turnoff mass of 1.3 M
⊙. We suggest the WD progenitor star formed several hundred megayears ago via the merger of two stars near the turnoff of the cluster. In this scenario, the original progenitor system was a hierarchical triple consisting of a close, near-equal-mass inner binary, with a tertiary companion with an orbit of a few thousand days. The WD is descended from the merged inner binary, and the original tertiary is now the observed BL. The likely formation scenario involves a common envelope while the WD progenitor is on the AGB, and thus the observed orbital period of 359 days requires an efficient common envelope ejection. The rapid rotation of the BL indicates it accreted some material during its evolution, perhaps via a wind prior to the common envelope. This system will likely undergo a second common envelope in the future and thus could result in a short-period double WD binary or merger of a 0.72 M
⊙ C/O WD and a 0.38 M
⊙ helium WD, making this a potential progenitor of an interesting transient such as a sub-Chandrasekhar Type Ia supernova.

Abstract
We present JWST Near Infrared Spectrograph (NIRSpec) measurements of the three largest low-albedo main-belt asteroids: (1) Ceres, (2) Pallas, and (10) Hygiea. Their reflectance spectra all have very similar absorptions centered near 2.72 μm attributed to Mg–OH in minerals. Within this band, Pallas also shows evidence of a sharper, deeper band, also centered near 2.72 μm. These band positions are similar to those seen in the most aqueously altered carbonaceous chondrites and samples from Ryugu and Bennu. Absorptions in the 2.7–2.9 μm region due to other cation–OH combinations are weak, if present. The NIRSpec spectrum of Ceres is consistent with the global average spectrum of Dawn, and the similarity between Ceres and Hygiea seen in other wavelength regions continues into the 2.5–2.8 μm region. This similarity in spectral properties, and thus in interpretations of surface composition, implies that the two bodies may have had similar processes occur and similar histories. This suggests that Hygiea, similar to Ceres, may be associated with the “ocean worlds” despite its relatively small mass. Quantitative estimates of the hydrogen concentrations on the surfaces suggest hydrogen concentrations of roughly 0.5–1 wt%, consistent with CM chondrites. Additional absorptions attributed to ammoniated minerals are seen in Ceres’s and Hygiea’s spectra, as has been reported by others, but are not seen in Pallas’s spectrum. Absorptions are also seen in the 2.5–2.7 μm region in all three asteroids, likely due to OH combination bands, and from roughly 3.9 to 4.3 μm in Hygiea, which could be due to carbonates plus an unidentified constituent.
Les grammaires italiennes dans la deuxième moitié du xixe siècle : entre théorie(s), histoire et société
Authors: Stancati Claudia 
Published: January 2025

L’auteure présente une esquisse historique des grammaires de
l’italien entre le moment de l’unification nationale (1861) et le début du xxe siècle afin de vérifier la
présence de différentes orientations théoriques et les liens de la recherche
linguistique italienne avec les diverses écoles européennes. Les textes
scientifiques montrent que l’italien présente plus d’une spécificité par rapport
aux langues romanes. En effet, il est considéré comme la langue la plus proche
du latin ; le nombre et le poids de ses dialectes, également pratiqués par les
personnes instruites, sont remarquables ; enfin, la langue écrite et la langue
littéraire sont davantage considérées que la langue parlée, cela en raison d’une
division politique vieille de plusieurs siècles. Dans un pays qui, pour la
première fois de son histoire, cherche enfin à bâtir une institution scolaire
nationale, tous ces nœuds théoriques influencent aussi les grammaires scolaires.
Ils répondent à la nécessité sociale et politique de traduire la questione della lingua en une didactique capable
d’enseigner la langue nationale à des usagers dialectophones dont la pratique
langagière est souvent très éloignée de cette langue commune qui vient d’être
fixée au prix de grandes discussions.
From Historical to Synchronic Linguistics in Greece: The Critical Decade of 1970s in Its Socio-Historical and Ideological Context
Authors: Giannaris Thanasis , Intzidis Evangelos , Karantzola Eleni 
Published: January 2025

Cet article est consacré à l’étude de l’introduction de la linguistique synchronique en Grèce dans les années 1970 et de la réorganisation de la discipline dans les universités grecques. En s’appuyant sur des sources jusqu’à présent peu étudiées (archives universitaires, annuaires, programmes d’étude, etc.) ainsi que sur des entretiens que nous avons conduits, nous décrivons en détail le passage de la linguistique historique à la linguistique synchronique. Nous soutenons, en outre, que ce changement a été influencé par les conditions socio-historiques et les idéologies qui prévalaient au cours de cette période. Enfin, étant donné qu’en 1976 la « question de la langue » est résolue, nous explorons comment la réorientation de la linguistique grecque vers l’état actuel du grec moderne interagit avec les idéologies langagières robustes des deux universités principales (d’Athènes et de Thessalonique).
Wüster/Carnap: Vienna School/Vienna Circle
Authors: Savatovsky Dan 
Published: January 2025

Cette contribution vise à mettre en évidence certaines des affinités théoriques entre la terminologie wüstérienne et la philosophie du langage du positivisme logique. Après avoir succinctement indiqué les raisons pour lesquelles la plupart des linguistes du vingtième siècle ont été réticents à « recevoir » la théorie de Wüster en raison de ses présupposés philosophiques, on s’efforce d’étudier quelques-uns de ces présupposés en mettant en regard les conceptions de l’école de Vienne de terminologie et celles du Cercle de Vienne (de Carnap, principalement). On examine tour à tour le recours au principe de parcimonie, la question du nominalisme et le problème de la définition réelle. On termine sur les conditions d’une culture matérielle, telles qu’elles se dégagent d’une terminologie/ontologie des objets techniques à la Wüster.
La Linguistic Society of America et ses effets sur la pratique de la linguistique aux États-Unis
Authors: Newmeyer Frederick J. 
Published: January 2025

Cet article se propose de comprendre comment la pratique des linguistes américains a été influencée au fil des ans par les traditions institutionnelles présentes aux États-Unis, en particulier par la politique de l’organisation principale du domaine, la Linguistic Society of America (LSA). Pendant les quinze premières années d’existence de la LSA, une lutte constante a eu lieu entre les défenseurs d’une conception de la linguistique comme science pure et les défenseurs d’une approche liée à la littérature et à la culture. Au début des années 1940, grâce aux efforts concertés de Leonard Bloomfield, Edward Sapir, et d’autres, les linguistes « scientifiques » ont gagné.
Les réseaux du style : une double méprise
Authors: Jollin-Bertocchi Sophie , Saint-Gerand Jacques-Philippe 
Published: January 2025

La réflexion sur le style comme expression spirituelle de l’art d’écrire développée en Allemagne à la fin du xviiie siècle, à laquelle renvoie le terme Stilistik, a été dévoyée en français sous la dénomination trompeuse de stylistique, qui – faux-ami – accrédite une conception matérialiste de l’application de procédés rhétoriques et grammaticaux. L’objectif du présent article est de montrer pourquoi et comment cette consciente méprise initiale a engendré au sein même de l’Université française des dernières décennies une seconde équivoque plus insidieuse au sujet de l’objet du style. Les travaux de Spitzer, Bally, Bruneau, Cressot, Riffaterre, Eco, Molinié, Bordas, Macé, montrent la nécessité de distinguer entre étude(s) de style et stylistique, mais cette dernière, devenue épreuve imposée des concours de recrutement de l’enseignement secondaire, a vu se démultiplier la publication d’innombrables manuels d’application aux fondements théoriques – grammaticaux, rhétoriques, linguistiques – largement hétérogènes. Ces ouvrages, que justifie la nécessité d’occuper une place du marché éditorial, ne concourent guère à l’approfondissement épistémique du style, notion susceptible de s’appliquer – hors de l’écriture – à bien des secteurs des activités humaines et des pratiques artistiques, mais manifestent l’existence d’un réseau d’intérêts pratiques et économiques dont la recherche ne tire malheureusement aucun bénéfice.
