ИСТОРИЧЕСКАЯ СОЦИОЛИНГВИСТИКА: ГРАНИЦЫ И ВОЗМОЖНОСТИ (НА МАТЕРИАЛЕ РОМАНСКИХ ЯЗЫКОВ)
Authors: Челышева Ирина Игоревна 
Published: August 2023

Статья посвящена проблематике исторической социолингвистики в приложении к романским языкам. Это исследовательское направление, с одной стороны, позиционируется как новое, но, с другой стороны, продолжает традиции классической романской филологии, рассматривавшей историю языка в контексте истории общества. Диахронический материал не дает возможности обращаться к непосредственному языковому опыту и лингвистической компетенции носителей языков, а объектом лингвистической рефлексии романские языки стали, в основном, лишь с XVI в. Однако на основании разнообразных экстралингвистических сведений и корпуса текстов определенной эпохи можно реконструировать языковую ситуацию, а в некоторых случаях воссоздать и ситуацию коммуникативную. Средневековое многоязычие романской Европы представлено в различных вариантах соотношения языков и сфер, ими обслуживаемых. Особое место занимает соотношение латынь vs. романские языки, обретавшее различные формы, начиная с момента формирования романских языков. Такие аспекты, как язык и этнос, язык и государство, языковая политика, также могут быть исследованы в приложении к прошлому. Наиболее сложным оказывается воссоздание социальной дифференциации языка прошлых эпох, поскольку диастратические варианты ограниченно представлены в текстах, а оценка их места в иерархии языкового варьирования затруднена.

Published: August 2023

In this paper, the aero-engine test with inter-shaft bearing fault is carried out, and a dataset is proposed for the first time based on the vibration signal of rotors and casings. First, a test rig based on a real aero-engine is established, driven by motors and equipped with a lubricating system. Then, the aero-engine is disassembled and assembled following the specification process, and the inter-shaft bearing with artificial fault is replaced. Next, the aero-engine test is conducted at 28 groups of high and low pressure speeds. Six measuring points are arranged, including two displacement sensors to test the displacement vibration signals of the low pressure rotor and four acceleration sensors to test the acceleration vibration signals of the casing. The test results are integrated into an inter-shaft bearing fault dataset. Finally, based on the dataset in this paper, frequency spectrum, envelope spectrum, CNN, LSTM and TST are used for fault diagnosis, and the results are compared with those of CWRU and XJTU datasets. The results show that the characteristic fault frequency cannot be found directly in the spectrum and envelope spectrum corresponding to this paper's dataset but in CWRU and XJTU datasets. Using CNN, LSTM and TST for fault diagnosis of the dataset in this paper, the accuracy is 83.13%, 85.41% and 71.07%, respectively, much lower than the diagnosis results of CWRU and XJTU datasets. It can be seen that the dataset in this paper is closer to the actual fault diagnosis situation and is a more challenging dataset. This dataset provides a new benchmark for the validation of fault diagnosis methods. Mendeley data: https://github.com/HouLeiHIT/HIT-dataset.

Abstract
Plumes are bright structures in coronal holes extending from the solar surface into the corona and are considered as a possible source of the solar wind. Plumes are thought to be rooted in strong unipolar photospheric flux patches (network/plage region). The magnetic activities at the base of plumes may play a crucial role in producing outflows and propagating disturbances (PDs). However, the role of photospheric/chromospheric activities (e.g., jets/spicules) at the base of plumes and their connection to PDs is poorly understood. Using high-resolution observations of a plume taken on 2020 July 23 with the 1.6 m Goode Solar Telescope (GST), Interface Region Imaging Spectrograph (IRIS), and the Atmospheric Imaging Assembly (AIA) on board the Solar Dynamics Observatory, we analyzed chromospheric/transition region activities at the base of the plume and their connection to outflows/PDs in the plume. The GST Visible Imaging Spectrometer images reveal repetitive spicules with blueshifted emission (pseudo-Doppler maps) at the plume’s footpoint. In addition, the photospheric magnetograms provide evidence of mixed polarities at the base of the plume. The IRIS Mg ii k Dopplergrams show strong blueshifted emission (∼50 km s−1) and a high brightness temperature (Mg ii k2 line) at the footpoint of the plume. The long-period PDs (P ≈ 20–25 minutes) along the plume (AIA 171 Å) match the periodicity of spicules in the chromospheric images, suggesting a close connection between the spicules and the PDs. We suggest that the interchange reconnection between the closed and open flux of the coronal bright point at the plume’s footpoint is the most likely candidate to produce upflows and associated PDs along the plume.

Abstract
We report the first measurement of polarized thermal dust emission toward the entire infrared dark cloud G11.11−0.12 taken by the polarimeter SOFIA/HAWC+ at 214 μm. The obtained magnetic fields (B-fields) from the polarized emission of the early-stage and massive filament tend to be perpendicular to its spine. We produce a map of B-field strengths for the center region of the filament. The strengths vary in the range of 100–600 μG and are strongest along the filament's spine. The central region is sub-Alfvénic and mostly subcritical, meaning that B-fields dominate over turbulence and are strong enough to resist gravitational collapse. The alignment and properties of dust grains in the filament are studied using radiative torque (RAT) theory. We find the decrease of polarization degree P with emission intensity I, i.e., depolarization effect, of the form P ∝ I
−α
with α ∼ 0.8–0.9, implying a significant loss of grain alignment in the filament's spine. The depolarization can be explained by the decrease in RAT alignment efficiency toward the denser regions with weaker radiation field, which cannot be explained by B-field tangling. We study the effect of the enhanced magnetic relaxation by embedded iron inclusions on RAT alignment and find that the high polarization fraction P ∼ 20%–30% in the outer layer of the filament is potential evidence for the magnetically enhanced RAT alignment mechanism. This is the first time this effect is evaluated in a filament. Based on the polarization fraction and RAT alignment theory, we also find evidence for grain growth in the filament.
Symmetry Breaking in Merging Binary Black Holes from Young Massive Clusters and Isolated Binaries
Authors: Banerjee Sambaran , Olejak Aleksandra , Belczynski Krzysztof 
Published: August 2023

Abstract
Properties of the to-date observed binary black hole (BBH) merger events suggest a preference toward spin–orbit aligned mergers. Naturally, this has caused widespread interest and speculations regarding implications on various merger formation channels. Here we show that (i) not only the BBH merger population from isolated binaries but also (ii) BBH population formed in young massive clusters (YMCs) would possess an asymmetry in favor of aligned mergers, in the distribution of the events’ effective spin parameter (χ
eff). In our analysis, we utilize BBH merger outcomes from state-of-the-art N-body evolutionary models of YMCs and isolated binary population synthesis. We incorporate, for the first time in such an analysis, misalignments due to both natal kicks and dynamical encounters. The YMC χ
eff distribution has a mean (an antialigned merger fraction) of 〈χ
eff〉 ≤ 0.04 (f

− ≈ 40%), which is smaller (larger) than but consistent with the observed asymmetry of 〈χ
eff〉 ≈ 0.06 (f

− ≈ 28%) as obtained from the population analysis by the LIGO–Virgo–KAGRA collaboration. In contrast, isolated binaries alone tend to produce a much stronger asymmetry; for the tested physical models, 〈χ
eff〉 ≈ 0.25 and f

X
− ≲ 7%. Although the YMC χ
eff distribution is more similar to the observed counterpart, none of the channels correctly reproduce the observed distribution. Our results suggest that further extensive model explorations for both isolated binary and dynamical channels as well as better observational constraints are necessary to understand the physics of “the symmetry breaking” of the BBH merger population.
ALMA ACA Detection of Submillimeter Emission Associated with the Western Hot Spot of the Radio Galaxy Pictor A

Published: August 2023

Abstract
In order to investigate the far-infrared excess detected from the western hot spot of the radio galaxy Pictor A with the Herschel observatory, submillimeter photometry is performed with the Atacama Compact Array (ACA) of the Atacama Large Millimeter/submillimeter Array at Band 8 with the reference frequency of 405 GHz. A submillimeter source is discovered at the radio peak of the hot spot. Because the 405 GHz flux density of the source, 80.7 ± 3.1 mJy, agrees with the extrapolation of the synchrotron radio spectrum, the far-infrared excess is suggested to exhibit no major contribution at the ACA band. In contrast, by subtracting the power-law spectrum tightly constrained by the radio and ACA data, the significance of the excess in the Herschel band is well confirmed. No diffuse submillimeter emission is detected within the ACA field of view, and thus, the excess is ascribed to the western hot spot itself. In comparison to the previous estimate based on the Herschel data, the relative contribution of the far-infrared excess is reduced by a factor of ∼1.5. The spectrum of the excess below the far-infrared band is determined to be harder than that of the diffusive shock acceleration. This strengthens the previous interpretation that the excess originates via the magnetic turbulence in the substructures within the hot spot. The ACA data are utilized to evaluate the magnetic field strength of the excess and of diffuse radio structure associated with the hot spot.
Coronal Loops with Different Metallicities and Generalized RTV Scaling Laws
Authors: Washinoue Haruka , Suzuki Takeru K. 
Published: August 2023

Abstract
Stellar metallicity is a critical factor to characterize the stellar coronae because it directly affects the radiative energy loss from the atmosphere. By extending theoretical relations for solar coronal loops introduced by Rosner et al., we analytically derive scaling relations for stellar coronal loops with various metallicities. In order to validate the derived relations, we also perform magnetohydrodynamic simulations for the heating of coronal loops with different metallicities by changing radiative-loss functions according to the adopted elemental abundances. The simulation results nicely explain the generalized analytical scaling relations and show a strong dependence of the thermodynamical and radiative properties of the loops on metallicity. Higher density and temperature are obtained in lower-metallicity coronae because of the inefficient radiative cooling, provided that the surface condition is unchanged. Thus, it is estimated that the X-ray radiation from metal-poor coronae is higher because of their denser coronal gas. The generalized scaling laws can also be used as a tool to study the condition of high-energy radiation around magnetically active stars and their impact on planetary environments.

Published: August 2023

Abstract
As one of the most energetic and brightest events, gamma-ray bursts (GRBs) can be treated as a promising probe of the high-redshift universe. Similar to type Ia supernovae, GRBs with the same physical origin could be treated as standard candles. We select GRB samples with the same physical origin, which are divided into two groups. The first group consists of 31 GRBs with a plateau phase feature of a constant luminosity followed by a decay index of about −2 in the X-ray afterglow light curves, and the second group has 50 GRBs with a shallow decay phase in the optical light curves. For the selected GRB samples, we confirm that there is a tight correlation between the plateau luminosity L

Empirical Findings on Associations Between Anxiety, Depression, and Congenital Heart Disease in Adults – A Systematic Review and Meta-Analysis
Authors: Abdullah Hani , Beckmann Jürgen , Andonian-Dierks Caroline 
Published: August 2023

Introduction:
Research on emotional distress in adults with congenital heart disease (ACHD) has raised concerns about its effects on quality of life (QOL) and future health risks. This study aims to identify the relationship between anxiety and/or depressive symptoms and congenital heart disease (CHD) in adults. It further explores the effect of depressive symptoms on QOL in ACHD.

Methods:
A systematic review and meta-analysis of the available literature was performed following the preferred reporting items for systematic reviews and meta-analyses guidelines. PubMed, Google Scholar, SAGE Journals, JSTOR, and ScienceDirect databases were also explored within this study. The data extraction was executed considering the aim of the study, study population (CHD patients 18 years or above), standardized measures to diagnose anxiety and depression. The pooled correlation coefficients (with 95% confidence interval [CI]) between symptoms of anxiety or depression and CHD in adults were estimated using R software. Potential heterogeneity was analyzed using meta-regression. Publication bias was evaluated using funnel plots, Egger's and rank test.

Results:
A total of 21 studies were selected for the systematic review. Fifteen studies, with a total of 16,079 participants, were included into the meta-analysis. Included studies show different study designs such as cohort, cross-sectional, case-control, and experimental design. The systematic review revealed heterogeneous results on anxiety or depressive symptoms in ACHD and their effect on QOL in ACHD. The pooled correlation coefficient between anxiety symptoms and CHD was 0.22 (95% CI: 0.00–0.43). Considering depressive symptoms and CHD, the pooled correlation coefficient was 0.04 (95% CI: -0.18–0.26). The pooled correlation coefficient between depressive symptoms and QOL in ACHD was 0.20 (95% CI: -0.49–0.10). Meta-regression analysis showed that the presence of depressive and anxiety symptoms, increasing age and the application of cross-sectional study design may have an important impact on the observed correlations.

Conclusion:
The present study confirms that anxiety is significantly associated with negative health outcomes in ACHD. Depression was not significantly associated with negative health outcomes in ACHD. The findings emphasize the importance of a holistic approach to cardiac care in which psychosocial support is an integral component in order to effectively enhance QOL and cardiovascular health in ACHD.
