Authors: Аблязов Э.К. , Аблязов К.А. 
Published: December 2023

В статье предлагается методика оценивания показателей надежности портовых перегрузочных машин (ППМ) с учетом ординарности и однородности потока отказов. В исследовании рассматривались отказы однотипных портовых перегрузочных машин в течение одного года эксплуатации. В основе оценивания показателей надежности ППМ используется статистическая информация об отказах автопогрузчиков "HYUNDAI 130D-7E" за календарный год. Под ординарностью потока отказов в данном исследовании предполагается, что одновременно возникает не более одного отказа, и без последействия. Оценка однородности потока отказов производится с использованием коэффициента вариации. Для определения числовых характеристик случайных величин и расчетных значений частот и эмпирической плотности вероятности, полученного статического материала об отказах, используется усеченное нормальное распределение. Предложен критерий проверки гипотезы о выборе закона распределения, поступающего потока отказов, группы автопогрузчиков ППМ ПАО «Новороссийский морской торговый порт».В исследовании рассматривается практический пример анализа статистической информации об отказах. Предполагается использования предложенного метода для оценивания показателей надежности однотипных портовых перегрузочных машин в практических целях.
The article proposes a methodology for estimating the reliability indicators of port transshipment machines (PPM), taking into account the ordinariness and uniformity of the flow of failures. The study considered failures of the same type of port handling machines during one year of operation. Statistical information about failures of HYUNDAI 130D-7E forklift trucks for a calendar year is used as the basis for evaluating the reliability indicators of the PPM. Under the ordinary nature of the failure flow in this study, it is assumed that no more than one failure occurs at a time, and without aftereffect. The assessment of the homogeneity of the failure flow is made using the coefficient of variation. Truncated normal distribution is used to determine the numerical characteristics of random variables and the calculated values of the frequencies and empirical probability density of the obtained static material on failures. A criterion for testing the hypothesis on the choice of the distribution law, the incoming failure flow, a group of PPM forklifts of PJSC "Novorossiysk Commercial Sea Port" is proposed. The study considers a practical example of the analysis of statistical information about failures. It is supposed to use the proposed method for evaluating the reliability indicators of the same type of port handling machines for practical purposes.

The relationship between neural phase entrainment and statistical word-learning: A scoping review
Authors: Sjuls Guro S. , Harvei Nora N. , Vulchanova Mila D. 
Published: December 2023

AbstractStatistical language-learning, the capacity to extract regularities from a continuous speech stream, arguably involves the ability to segment the stream before the discrete constituents can be stored in memory. According to recent accounts, the segmentation process is reflected in the alignment of neural activity to the statistical structure embedded in the input. However, the degree to which it can predict the subsequent leaning outcome is currently unclear. As this is a relatively new avenue of research on statistical learning, a scoping review approach was adopted to identify and explore the current body of evidence on the use of neural phase entrainment as a measure of online neural statistical language-learning and its relation to the learning outcome, as well as the design characteristics of these studies. All included studies (11) observed entrainment to the underlying statistical pattern with exposure to the structured speech stream. A significant association between entrainment and learning outcome was observed in six of the studies. We discuss these findings in light of what neural entrainment in statistical word-learning experiments might represent, and speculate that it might reflect a general auditory processing mechanism, rather than segmentation of the speech stream per se. Lastly, as we find the current selection of studies to provide inconclusive evidence for neural entrainment’s role in statistical learning, future research avenues are proposed.
Simplification principles and child language development in Armenian
Authors: Hovhannisyan Hasmik , Dolatian Hossep 
Published: December 2023

At certain stages of their general cognitive development and language acquisition, children apparently employ their innately growing (cognitive) knowledge and skills to meet the challenges they face in L1 acquisition. Among other things, children use different sets of simplification strategies, such as cropping words, replacing or displacing syllables or syllabic constituents, omitting suffixes, and using simpler syntax. We catalog processes like fortition, reduplication, and the various stages of acquisition. This paper presents some language development data in Armenian children. Empirically, our study is one of the few (if only) known studies on the language acquisition of Armenian. The data provides valuable theoretical insight into the strategies that children pursue in communication, as well as in cognitive processing of speech.

Authors: Duran Barco Hemer Stiwar , Sanchez Caicedo Luis Gabriel 
Published: December 2023

El presente artículo pretende exponer las diferentes tensiones que se presentan al momento de analizar la eficacia del principio de oportunidad en material laboral para las poblaciones afrodescendientes del país, así como también la profundización del fenómeno de la discriminación laboral hacia las mismas, pues este último se ha convertido en una barrera que complejiza el panorama socioeconómico de la comunidad afrodescendiente y en mismo modo, no permite el pleno goce de derechos tales como el trabajo. Precisamente, el principio de oportunidad en materia laboral ha tenido un importante desarrollo en cuanto a la protección jurídica a nivel internacional y nacional; Sin embargo, al momento de materializarse e introducirse en los ordenamientos jurídicos internos, como el de Colombia, se observan diferentes dificultades para lograr su concreción. En este sentido, el texto aborda las diferentes limitaciones del principio de igualdad de oportunidades tales como la desigualdad estructural, los bajos estándares de educación, la marginalidad, el desempleo y la pobreza.

A New Covariant Formalism for Kinetic Plasma Simulations in Curved Spacetimes
Authors: Trent Tyler , Christian Pierre , Chan Chi-kwan , Psaltis Dimitrios , Özel Feryal 
Published: December 2023

Abstract
Low-density plasmas are characterized by a large-scale separation between the gyromotion of particles around local magnetic fields and the macroscopic scales of the system, often making global kinetic simulations computationally intractable. The guiding center formalism has been proposed as a powerful tool to bridge the gap between these scales. Despite its usefulness, the guiding center approach has been formulated successfully only in flat spacetimes, limiting its applicability in astrophysical settings. Here, we present a new covariant formalism that leads to kinetic equations in the guiding center limit that are valid in arbitrary spacetimes. Through a variety of experiments, we demonstrate that our equations capture all known gyrocenter drifts while overcoming one severe limitation imposed on numerical algorithms by the fast timescales of the particle gyromotion. This formalism will enable explorations of a variety of global plasma kinetic phenomena in the curved spacetimes around black holes and neutron stars.

Abstract
We report the measurement of the sky-projected obliquity angle λ of the warm Jovian exoplanet TOI-1670 c via the Rossiter–McLaughlin effect. We observed the transit window during UT 2023 April 20 for 7 continuous hours with NEID on the 3.5 m WIYN Telescope at Kitt Peak National Observatory. TOI-1670 hosts a sub-Neptune (P ∼ 11 days; planet b) interior to the warm Jovian (P ∼ 40 days; planet c), which presents an opportunity to investigate the dynamics of a warm Jupiter with an inner companion. Additionally, TOI-1670 c is now among the longest-period planets to date to have its sky-projected obliquity angle measured. We find planet c is well aligned to the host star, with λ = − 0.°3 ± 2.°2. TOI-1670 c joins a growing census of aligned warm Jupiters around single stars and aligned planets in multiplanet systems.
Soft X-Ray Excess from Shocked Black Hole Accretion
Authors: Przybylek Jeff , Fukumura Keigo 
Published: December 2023

Abstract
A certain class of luminous galaxies hosting supermassive black holes (BHs) is known to exhibit an excess of “soft X-rays” in their X-ray spectra. However, its physical identity and origin are yet to be understood. In this work, we systematically study a sample of 9 well-documented narrow-line Seyfert 1 active galactic nuclei by utilizing the archival XMM-Newton/EPIC spectra in the context of general relativistic magnetohydrodynamic model. In this scenario, thermal accretion disk photons (in UV) are Compton up-scattered by nonthermal energetic electrons in the hot downstream accretion due to shock compression, producing the observed soft excess. Our spectral model consists primarily of the shock Comptonization component and the underlying continuum including reflection from the accretion disk. Based on χ
2-statistics, we successfully constrain the model parameters, most notably electron energy of the downstream flow kT

e
, effective disk blackbody temperature kT
bb, and inclination angle θ for a given BH spin. The disk temperature is commonly found to be kT
bb 10 eV and the electron energy ranges from kT

e
75–160 keV (for Schwarzschild BHs) to 126–232 keV (for Kerr BHs) depending on inclination. Our analyses imply that the characteristics of the observed soft excess are strongly dependent on the properties of the downstream accretion flow and BH spin.
New Pulsating Variable Stars and Eclipsing Binaries in NGC 6871*
Authors: Zhou Ai-Ying 
Published: December 2023

Abstract
Leveraging publicly available Transiting Exoplanet Survey Satellite data, I conducted a small regional survey centered on the δ Scuti star V1821 Cyg in the open cluster NGC 6871, spanning a radius of 1°. This survey yielded a remarkable 1530 newly classified variable stars, encompassing: 198 eclipsing binary systems, 12 of which exhibit pulsating or rotating components, 105 γ Doradus stars, 116 δ Scuti stars, 526 rotating variable stars, and dozens of other types. It is not surprising that no RR Lyrae stars were found in this particular young open cluster.
Visible and Near-infrared Spectral Properties of Martian Slope Streaks
Authors: Kaplan H. H. , Stillman D. E. , Hoover R. , Michaels T. , Fenton L. , Primm K. M. 
Published: December 2023

Abstract
Martian slope streaks are large surface features with lower albedo than their surroundings that are one of the few active geologic processes occurring on Mars today. We investigated the slope streaks’ spectral properties using images from the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) at nine sites, including three sites with observations over multiple years to enable time-series analysis. For each individual slope streak within each image, we determined the average spectra of each streak and of the slope immediately adjacent to account for changes in geology across a CRISM image or within slopes containing streaks. We find a trend where the visible spectral continuum (0.4–0.6 μm) is strongly negative for the darkest slope streaks, and the spectral continuum increases as the slope streaks fade, consistent across all sites and over multiple observations of the same site. We do not find absorption at 1.4 or 1.9 μm associated with hydration. In some slope streaks, we see evidence of Fe-bearing minerals, but these signatures are also found in the streak-free slope directly adjacent, suggesting that the streaks have a similar mineralogy to their surroundings. The spectral changes that we see are most consistent with changes in the fine dust component and support a dry flow mechanism whereby slope streaks are formed by processes that trigger dust removal from the slope in particular locations, with the streaks slowly fading as dust resettles on the surface.
Les abbesses de la Trinité de Caen, la reine Mathilde et l’Angleterre
Authors: Letouzey-Réty Catherine 
Published: December 2023

Cet article se propose d’aborder l’année 1066 selon un autre point de vue, celui des religieuses et des abbesses de la Sainte-Trinité de Caen. Le texte le plus ancien conservé pour cette abbaye, la grande charte de « fondation » du 18 juin 1066 – bien connue des chercheurs – lie d’emblée les religieuses aux réalisations du couple ducal quelques mois avant la bataille d’Hastings. La victoire de Guillaume a des retombées économiques immédiates pour l’abbaye, qui bénéficie du patronage énergique de la reine Mathilde. Avec l’appui de son époux, cette dernière s’attache en particulier à étendre le temporel de sa fondation caennaise vers l’Angleterre. Le propos s’attache à examiner le sens qu’a pu revêtir la date de 1066 pour les religieuses, et interroge quelques-unes des spécificités de son ancrage à l’Angleterre à partir de cette date.
Ego Wilhelmus victoriosus Anglorum basileus. Les circonstances de la synthèse impériale anglo-normande
Authors: Mureşan Dan Ioan 
Published: December 2023

Cette étude tente d’élucider la question de l’origine des laudes « poétiques » publiées par E. Henderson et H.E.J. Cowdrey et restées jusqu’à présent sans une contextualisation satisfaisante. Analysant leur tradition manuscrite et leur lien génétique avec la figure d’Ealdred, évêque de Worcester (1046-1061) et archevêque d’York (1061-1069), nous les réintitulons laudes impériales anglaises , en raison de leur focalisation sur l’image du basileus Anglorum . Dans un premier temps, nous les rattachons au contexte des couronnements royaux de Guillaume I er et de Mathilde en 1066 et 1068, mettant en lumière le fait que l’emploi du titre de basileus Anglorum dans certaines chartes du roi n’est qu’un reflet de la performance publique des laudes impériales à ces occasions. Remontant dans le temps au règne d’Édouard le Confesseur, nous argumentons que la genèse de ces laudes est un effet immédiat du pèlerinage d’Ealdred, encore évêque de Worcester, à Jérusalem et à son passage à Constantinople, sous le règne d’Isaac I er Comnène en 1060-1061, étant conçues à l’occasion de son intronisation comme archevêque d’York, en présence du roi Édouard et de la reine Edith. L’auteur intellectuel de ces laudes et de la musique qui les accompagnait est vraisemblablement Folcard de Saint-Bertin, auteur de la Vita Ædwardi Regis également. Elles sont donc à rattacher aux transformations profondes de la représentation royale d’Édouard le Confesseur dans le sens d’une influence byzantine et ottonienne, mises en lumière par l’analyse du sceau royal de l’époque. En dernier lieu, nous argumentons que la représentation impériale du pouvoir royal anglo-normand ne discontinua pas avec la mort d’Ealdred d’York en 1069 et la cessation d’usage du titre de basileus Anglorum dans les chartes postérieures à cette date. Elle a été au contraire sublimée dans l’œuvre de Guillaume de Poitiers par la métamorphose de la figure de Guillaume en imperator chrétien ayant pour modèle Théodose le Grand (379-395).
De Guillaume I er à Roger II de Sicile : autour de l’impérialité des premiers couronnements royaux normands (1066-1130)
Authors: Peters-Custot Annick , Madeline Fanny 
Published: December 2023

Les cérémonies de couronnement de Guillaume I er en 1066 et de Roger II en 1130 relèvent chacune de la sacralité royale, mais tous deux expriment, à partir du rituel de couronnement et des artéfacts qui lui sont liés, leur revendication à régner impérialement en leur royaume. Pour cela, ils mobilisent une multitude de références qu’ils empruntent au répertoire extrêmement polysémique de l’ imperium. En les agrégeant au rituel de couronnement, ils en font le support d’un syncrétisme idéologique qui a marqué les esprits, au-delà de toute cohérence avec la réalité de leurs pratiques de gouvernement. L’unité liturgique entre les royaumes normands d’Angleterre et de Sicile nous permet d’aborder de manière parallèle les différences et les similitudes entre ces deux cérémonies, au cours desquelles les marques de l’impérialité donnaient à voir l’idée que l’empire était, pour tous deux, un horizon des possibles.
Guillaume le Conquérant a-t-il rattaché l’Angleterre au continent ?
Authors: Genêt Jean-Philippe 
Published: December 2023

La nature de la relation entre l’Angleterre et le continent a hanté l’historiographie britannique et a fortiori celle des conséquences de la conquête normande. Pour comprendre l’impact de celle-ci sur cette relation, il importe d’abord de l’évaluer avant 1066 : l’Angleterre anglo-saxonne n’est nullement isolée, elle a subi l’influence carolingienne et elle connaît aussi les prémisses de la mise en place du féodalisme et de la réforme grégorienne, même si la conquête accélérera brutalement l’évolution dans ces deux domaines. Mais au-delà des événements militaires et des changments politiques et administratifs, la transformation essentielle qu’elle introduit est l’imposition d’une nouvelle classe dominante. Cependant, la structure bipartite de cette classe que produit la redistribution des domaines des élites anglo-saxonnes permet paradoxalement une rapide ré-anglicisation des élites aristocratiques et leur implication dans le fonctionnement institutionnel administratif et judiciaire du royaume la classe les détourne progressivement du continent dont elles étaient issues.
