Published: July 2024

В данной статье рассматривается применение факторного статистического анализа для изучения влияния различных факторов на гендерное неравенство. Разработана система показателей, которая помогает определить экономическую, социальную и политическую среду, влияющую на гендерное развитие. Для проверки эффективности этой системы была использована методика расчета главных компонент на всероссийских официальных статистических данных. В ходе исследования были выявлены две главные компоненты, которые имеют значительное влияние на формирование гендерных различий. Первая компонента связана с экономическим ростом, а вторая - с социальным благополучием. Эти два фактора оказывают существенное воздействие на равенство возможностей между мужчинами и женщинами. Результаты данного исследования могут быть полезны для разработки стратегий и программ, направленных на преодоление гендерного неравенства. Они предоставляют ценную информацию для разработчиков политики и принимающих решения, чтобы создать равные возможности для обоих полов.
This article discusses the use of factor statistical analysis to study the impact of various factors on gender inequality. A system of indicators has been developed that helps to determine the economic, social and political environment that affects gender development. To test the effectiveness of this system, the method of calculating the main components on the All-Russian official statistical data was used. The study identified two main components that have a significant impact on the formation of gender differences. The first component is related to economic growth, and the second is related to social well-being. These two factors have a significant impact on equality of opportunity between men and women. The results of this study can be useful for the development of strategies and programs aimed at overcoming gender inequality. They provide valuable information for policy makers and decision makers to create equal opportunities for both genders.

Published: July 2024

Abstract
This study investigated the mechanical properties (elastic modulus, tensile strength, yield strength, and toughness) of different percent C of silicon carbide (SiC) using molecular dynamics simulations via the large-scale atomic/molecular massively parallel simulator (LAMMPS) with the uniaxial tensile test at four strain rates: 0.1, 0.5, 1.0, and 5.0 m s−1, using the Tersoff potential. The simulation uses 20 × 20 × 20 atoms (108.6 Å × 108.6 Å × 108.6 Å) of the diamond cubic structure of Si, then carbon atoms were placed randomly at 5% intervals from 0–50 percent C. Results show improved mechanical properties when increasing percent C until peaking at 25%, before decreasing. This is caused by the shortest bond length at 25 percent C from the increase of Si=C using the radial distribution function analysis. Increasing the strain rate generally improves the mechanical properties of the material. The deformation mechanism shows that increasing (decreasing) strain rate generally results in multiple (lesser) failure points with a ductile (brittle) fracture mode.
Characterization of electron extraction from a 40.68 MHz radiofrequency inductive plasma source
Authors: Kikuchi Kodai , Takahashi Kazunori 
Published: July 2024

Abstract
An electron current is extracted from a 40.68 MHz inductively coupled plasma source, in which a grounded ion collector electrode is installed to maintain the charge neutrality, by applying a positive voltage to a metallic plate located downstream of the source. The ion collector has an exit orifice of either 20 mm or 2.2 mm in diameter, showing a larger electron extraction current for the 2.2 mm-diameter case. The result is discussed with a global model, implying a higher plasma density for the 2.2 mm-diameter case due to the increased neutral pressure in the source. Metallic and insulator exits having a 2.2 mm-diameter orifice are tested, providing a larger electron extraction current for the metallic case despite a small fraction of a change in the total ion collection area. It is speculated that the electron extraction current is affected by the ion collection near the electron extraction hole and the potential distribution.

Os aneurismas cerebrais representam uma condição médica grave que pode levar a complicações severas e até fatais se não forem tratados adequadamente. Nos últimos anos, as abordagens cirúrgicas, sendo elas a embolização endovascular e o clipping neurocirúrgico assistido por endoscopia, tem emergido como alternativas eficazes aos métodos tradicionais. Estas técnicas oferecem a promessa de menos trauma cirúrgico, recuperação mais rápida e melhores resultados para o paciente. Objetivo: Comparar as técnicas minimamente invasivas de embolização endovascular e clipping neurocirúrgico assistido por endoscopia no tratamento de aneurismas cerebrais, avaliado suas eficácias, vantagens, desvantagens e resultados clínicos. Metodologia: A pesquisa foi conduzida por meio de acesso online às bases de dados Documentação em Ciências da Saúde da América Latina e do Caribe (LILACS), Centro de Informação em Ciências da Saúde da América Latina e do Caribe (Bireme), Scientific Electronic Library Online (SCIELO) e Biblioteca Virtual em Saúde (BVS) durante o mês de julho de 2024. Resultados e Discussão: A comparação entre as técnicas cirúrgicas para o tratamento de aneurismas, revela a diferença significativas em termos de eficácia. A embolização mostrou-se altamente eficaz com uma taxa de sucesso de 90%, pacientes submetidos a essa técnica apresentaram menor tempo de recuperação a menores taxas de complicações pós-operatórias em comparação com o clipping. No entanto, cada técnica apresenta suas limitações. A embolização endovascular pode não ser adequada para todos os tipos de aneurismas, e há riscos de recanalização ao longo do tempo. Considerações Finais: A escolha da abordagem mais adequada deve-se considerar a especificidade dos aneurismas e a condição do paciente. Ambas as técnicas têm mostrado resultados promissores, contribuindo para uma recuperação mais rápida e menor riscos de complicações, destacando a importância de uma abordagem personalizada no tratamento de aneurismas cerebrais.
Everything, altogether, all at once: Addressing data challenges when measuring speech intelligibility through entropy scores
Authors: Espejo Jose Manuel Rivera , De Maeyer Sven , Gillis Steven 
Published: July 2024

AbstractWhen investigating unobservable, complex traits, data collection and aggregation processes can introduce distinctive features to the data such as boundedness, measurement error, clustering, outliers, and heteroscedasticity. Failure to collectively address these features can result in statistical challenges that prevent the investigation of hypotheses regarding these traits. This study aimed to demonstrate the efficacy of the Bayesian beta-proportion generalized linear latent and mixed model (beta-proportion GLLAMM) (Rabe-Hesketh et al., Psychometrika, 69(2), 167–90, 2004a, Journal of Econometrics, 128(2), 301–23, 2004c, 2004b; Skrondal and Rabe-Hesketh 2004) in handling data features when exploring research hypotheses concerning speech intelligibility. To achieve this objective, the study reexamined data from transcriptions of spontaneous speech samples initially collected by Boonen et al. (Journal of Child Language, 50(1), 78–103, 2023). The data were aggregated into entropy scores. The research compared the prediction accuracy of the beta-proportion GLLAMM with the normal linear mixed model (LMM) (Holmes et al., 2019) and investigated its capacity to estimate a latent intelligibility from entropy scores. The study also illustrated how hypotheses concerning the impact of speaker-related factors on intelligibility can be explored with the proposed model. The beta-proportion GLLAMM was not free of challenges; its implementation required formulating assumptions about the data-generating process and knowledge of probabilistic programming languages, both central to Bayesian methods. Nevertheless, results indicated the superiority of the model in predicting empirical phenomena over the normal LMM, and its ability to quantify a latent potential intelligibility. Additionally, the proposed model facilitated the exploration of hypotheses concerning speaker-related factors and intelligibility. Ultimately, this research has implications for researchers and data analysts interested in quantitatively measuring intricate, unobservable constructs while accurately predicting the empirical phenomena.

Abstract
We present a multiwavelength analysis of the young star cluster Berkeley 59, based on Gaia data and deep IR observations with the 3.58 m Telescopio Nazionale Galileo and Spitzer space telescope. The mean proper motion of the cluster is found to be μ

α
cosδ ∼ −0.63 mas yr−1 and μ

δ
∼ −1.83 mas yr−1, and the kinematic distance of the cluster, ∼1 kpc, is in agreement with previous photometric studies. The present data are the deepest available near-IR observations for the cluster so far and reach below 0.03 M
⊙. The mass function of the cluster region is calculated using the statistically cleaned color–magnitude diagram and is similar to the Salpeter value for the member stars above 0.4 M
⊙. In contrast, the slope becomes shallower (Γ ∼ 0.01 ± 0.18) in the mass range 0.04–0.4 M
⊙, comparable to other nearby clusters. The spatial distribution of young brown dwarfs (BDs) and stellar candidates shows a nonhomogeneous distribution. This suggests that the radiation feedback from massive stars may be a prominent factor contributing to the BD population in the cluster Berkeley 59. We also estimated the star-to-BD ratio for the cluster, which is found to be ∼3.6. The Kolmogorov–Smirnov test shows that the stellar and BD populations significantly differ, and stellar candidates are nearer the cluster center compared to the BDs, suggesting mass segregation in the cluster toward the substellar mass regime.
Galactic Cirri at High Galactic Latitudes. I. Investigating Scatter in Slopes between Optical and Far-infrared Intensities

Abstract
Based on the slopes between DESI g, r and Infrared Astronomical Satellite (IRAS) 100 μm intensities, specifically k

g
and k

r
, we have constructed a substantial sample of Galactic cirri. This sample covers 561.25 deg2 at high Galactic latitudes (∣b∣ ≥ 30°), allowing for a systematic study of the physical parameters of the Galactic cirrus on a large scale, such as g − r color, dust temperature, asymmetry factor, and albedo. The ratio of k

g
and k

r
is consistent with the diffuse Galactic starlight model, suggesting that the diffuse starlight within our own Galaxy serves as the primary illumination source for the cirrus. Both k

g
and k

r
decrease slowly with increasing Galactic latitudes and IRAS 100 μm intensities, while they do not have a correlation with Galactic longitudes. The distribution of k

g
and k

r
confirms a significant scatter in the slopes, reaching a factor of 4–5. Such large scatter cannot be explained by the weak correlation between the slopes and Galactic latitudes and IRAS 100 μm intensities. Instead, it is attributed to substantial variations in the intrinsic properties of the dust, e.g., asymmetry factor and albedo. We propose that the properties of dust particles play a critical role in the observed scatter in slopes, making them the primary contributing factors. Moreover, the variations in dust properties within the cirrus are localized rather than exhibiting large-scale gradients.

Abstract
The classical T Tauri star (CTTS) stage is a critical phase of the star and planet formation process. In an effort to better understand the mass accretion processes, which can dictate future stellar evolution and planet formation, a multiepoch, multiwavelength photometric and spectroscopic monitoring campaign of four CTTSs (TW Hya, RU Lup, BP Tau, and GM Aur) was carried out in 2021 and 2022/2023 as part of the Outflows and Disks around Young Stars: Synergies for the Exploration of ULLYSES Spectra program. Here we focus on the Hubble Space Telescope (HST) UV spectra obtained by the HST Director’s Discretionary Time UV Legacy Library of Young Stars as Essential Standards (ULLYSES) program. Using accretion shock modeling, we find that all targets exhibit accretion variability, varying from short increases in accretion rate by up to a factor of 3 within 48 hr to longer decreases in accretion rate by a factor of 2.5 over the course of 1 yr. This is despite the generally consistent accretion morphology within each target. Additionally, we test empirical relationships between accretion rate and UV luminosity and find stark differences, showing that these relationships should not be used to estimate the accretion rate for an individual target. Our work reinforces that future multiepoch and simultaneous multiwavelength studies are critical in our understanding of the accretion process in low-mass star formation.
Experimental Vapor Pressure Determination for C2H4, C2H6, CH3OH, CH4, CO, CO2, H2O, and N2 Molecules for Astrophysical Relevant Temperatures. Implications for the Presence of Volatiles in Kuiper Belt Objects and Trans-Neptunian Objects

Published: July 2024

Abstract
Vapor pressure is a relevant quantity that is necessary in order to improve the study of the atmosphere dynamics that take place within astrophysical scenarios. The aim of this study was to obtain the vapor pressure values of the following molecules: C2H4, C2H6, CH3OH, CH4, CO, CO2, H2O, and N2 through experimentation, as well as to determine their empirical relationship with the temperature, applying the results to the persistence of volatiles in trans-Neptunian objects (TNOs) and Kuiper Belt objects (KBOs). The experimental determination was performed by measuring the sublimation rate for each molecule at different temperatures. The Hertz–Knudsen equation was used to obtain the vapor pressures for the aforementioned molecules, taking the necessary considerations into account, and the sublimation rate was measured using a quartz crystal microbalance. In order to check the validity of the methods used, the results obtained for water ice were compared with those of previous studies from the literature. The values obtained for CO, N2, and CH4 are of particular interest in the study of the TNOs' and KBOs' atmosphere composition. The results of this study improve the understanding of the surface and atmospheric composition of objects in the cold scenarios of the solar system, in particular, in KBOs and TNOs.

Abstract
The tidal disruption event (TDE) AT2018fyk has unusual X-ray, UV, and optical light curves that decay over the first ∼600 days, rebrighten, and decay again around 1200 days. We explain this behavior as a one-off TDE associated with a massive black hole (BH) binary. The sharp drop-offs from t
−5/3 power laws at around 600 days naturally arise when one BH interrupts the debris fallback onto the other BH. The BH mass M
• derived from fitting X-ray spectra with a slim disk accretion model and, independently, from fitting the early UV/optical light curves, is smaller by 2 orders of magnitude than predicted from the M
•–σ
* host galaxy relation, suggesting that the debris is accreted onto the secondary, with the fallback cut off by the primary. Furthermore, if the rebrightening were associated with the primary, it should occur around 5000 days, not the observed 1200 days. The secondary’s mass and dimensionless spin is

An intermediate mass BH secondary is consistent with the observed UV/optical light-curve decay, i.e., the secondary’s outer accretion disk is too faint to produce a detectable emission floor. The time of the first accretion cutoff constrains the binary separation to be (6.7 ± 1.2) × 10−3 pc. X-ray spectral fitting and timing analyses indicate that the hard X-rays arise from a corona above the secondary’s disk. The early UV/optical emission, suggesting a super-Eddington phase for the secondary, possibly originates from shocks arising from debris circularization.

Abstract
The Atacama Large Millimeter/Submillimeter Array has revolutionized the field of dust polarization in protoplanetary disks across multiple wavelengths. Previous observations and empirical modeling have suggested multiple mechanisms of dust polarization toward HL Tau, including grain alignment and dust scattering. However, a detailed modeling of dust polarization based on grain alignment physics is not yet available. Here, using an updated POLARIS code, we perform numerical modeling of dust polarization arising from both grain alignment by the magnetically enhanced radiative torque mechanism and self-scattering to reproduce the HL Tau polarization observed at three wavelengths of 0.87, 1.3, and 3.1 mm. Our modeling results show that the observed multiwavelength polarization could be reproduced only when large grains contain embedded iron inclusions and those with slow internal relaxation must have wrong internal alignment (i.e., the grain’s major axis parallel to its angular momentum). The abundance of iron embedded inside grains in the form of clusters is constrained to be ≳16%, and the number of iron atoms per cluster is N
cl ∼ 9 × 102. Maximum grain sizes probed at wavelengths of λ = 0.87, 1.3, and 3.1 mm are constrained at ∼60, 80, and 90 μm, respectively.
