On the Formation of the Public Condemnation of Epoch-making Korean Poet Sŏ Chŏngju – With a Focus on Pro-Japanese Collaboration
Authors: Kovács Janka 
Published: November 2022

Sŏ Chŏngju is no doubt one of the most significant poets of 20th century Korean literature. However, his figure is shrouded in controversies originating from his political choices in life. The first of these controversies is his being a ‘pro-Japanese collaborator’ during the Japanese colonial period. The purpose of this study is to move beyond the accusation of Sŏ Chŏngju being an collaborator to map the settings of the colonial background in which he lived and wrote, while also comparing his situation with that of the famous writer, I Kwangsu. Another goal of the study is to examine the approach to his figure and works in recent times. This is for the sake of gaining a deeper understanding of the important poet, who very often is cast away by the superficial criticism of his being a ‘collaborator’.
Evolution, Structure, and Topology of Self-generated Turbulent Reconnection Layers
Authors: Beg Raheem , Russell Alexander J. B. , Hornig Gunnar 
Published: November 2022

Abstract
We present a 3D MHD simulation of two merging flux ropes exhibiting self-generated and self-sustaining turbulent reconnection (SGTR) that is fully 3D and fast. The exploration of SGTR is crucial for understanding the relationship between MHD turbulence and magnetic reconnection in astrophysical contexts including the solar corona. We investigate the pathway toward SGTR and apply novel tools to analyze the structure and topology of the reconnection layer. The simulation proceeds from 2.5D Sweet–Parker reconnection to 2.5D nonlinear tearing, followed by a dynamic transition to a final SGTR phase that is globally quasi-stationary. The transition phase is dominated by a kink instability of a large “cat-eye” flux rope and the proliferation of a broad stochastic layer. The reconnection layer has two general characteristic thickness scales, which correlate with the reconnection rate and differ by a factor of approximately six: an inner scale corresponding with current and vorticity densities, turbulent fluctuations, and outflow jets, and an outer scale associated with field line stochasticity. The effective thickness of the reconnection layer is the inner scale of the effective reconnection electric field produced by turbulent fluctuations, not the stochastic thickness. The dynamics within the reconnection layer are closely linked with flux rope structures that are highly topologically complicated. Explorations of the flux rope structures and distinctive intermediate regions between the inner core and stochastic separatrices (“SGTR wings”) are potentially key to understanding SGTR. The study concludes with a discussion on the apparent dualism between plasmoid-mediated and stochastic perspectives on SGTR.

Abstract
We present the results of the analysis of the photometric data collected in long- and short-cadence mode by the Transiting Exoplanet Survey Satellite for GJ 504, a well-studied planet-hosting solar-like star, whose fundamental parameters have been largely debated during the last decade. Several attempts have been made by the present authors to isolate the oscillatory properties expected on this main-sequence star, but we did not find any presence of solar-like pulsations. The suppression of the amplitude of the acoustic modes can be explained by the high level of magnetic activity revealed for this target, not only by the study of the photometric light curve but also by the analysis of three decades of available Mount Wilson spectroscopic data. In particular, our measurements of the stellar rotational period P
rot ≃ 3.4 days and of the main principal magnetic cycle of ≃12 yr confirm previous findings and allow us to locate this star in the early main-sequence phase of its evolution during which the chromospheric activity is dominated by the superposition of several cycles before the transition to the phase of the magnetic-braking shutdown with the subsequent decrease of the magnetic activity.
Flexible Models for Galaxy Star Formation Histories Both Shift and Scramble the Optical Color–Mass-to-light Ratio (M/L) Relationship
Authors: Li 李 Yijia 轶佳 , Leja Joel 
Published: November 2022

Abstract
The remarkably tight relationship between galaxy optical color and stellar mass-to-light ratio (M
*/L) is widely used for efficient stellar mass estimates. However, it remains unclear whether this low scatter comes from a natural order in the galaxy population, or whether it is driven by simple relationships in the models used to describe them. In this work, we investigate the origins of the relationship by contrasting the derived relationship from a simple 4 parameter spectral energy distribution (SED) model with a more sophisticated 14D Prospector–α model including nonparametric star formation histories (SFHs). We apply these models to 63,430 galaxies at 0.5 < z < 3 and fit a hierarchical Bayesian model (HBM) to the population distribution in the (g − r)–

log

plane. We find that Prospector–α infers systematically higher M
*/L by 0.12 dex, a result of nonparametric SFHs producing older ages, and also systematically redder rest frame (g − r) by 0.06 mag owing to the contribution from nebular emission. Surprisingly, the combined effects of the M
*/L and (g − r) offsets produce a similar average relationship for the two models; though Prospector–α produces a higher scatter of 0.28 dex compared to the simple model of 0.12 dex. Also, unlike the simple model, the Prospector–α relationship shows substantial redshift evolution due to stellar aging. These expected and testable effects produce overall older and redder galaxies; though the color–M
*/L relationship is measured only at 0.5 < z < 3. Finally, we demonstrate that the HBM produces substantial shrinkage in the individual posteriors of faint galaxies, an important first step toward using the observed galaxy population directly to inform the SED-fitting priors.

Abstract
Planetary climates are strongly affected by planetary orbital parameters such as obliquity, eccentricity, and precession. In exoplanetary systems, exoterrestrial planets should have various obliquities. High-obliquity planets would have extreme seasonal cycles due to the seasonal change of the distribution of the insolation. Here, we introduce the Non-hydrostatic ICosahedral Atmospheric Model (NICAM), a global cloud-resolving model, to investigate the climate of high-obliquity planets. This model can explicitly simulate a three-dimensional cloud distribution and vertical transports of water vapor. We simulated exoterrestrial climates with high resolution using the supercomputer FUGAKU. We assumed aqua-planet configurations with 1 bar of air as a background atmosphere, with four different obliquities (0°, 23.5°, 45°, and 60°). We ran two sets of simulations: (1) low resolution (∼220 km mesh as the standard resolution of a general circulation model for exoplanetary science) with parameterization for cloud formation, and (2) high resolution (∼14 km mesh) with an explicit cloud microphysics scheme. Results suggest that high-resolution simulations with an explicit treatment of cloud microphysics reveal warmer climates due to less low cloud fraction and a large amount of water vapor in the atmosphere. It implies that treatments of cloud-related processes lead to a difference between different resolutions in climatic regimes in cases with high obliquities.
Spectroscopic Confirmation of Two X-Ray Diffuse and Massive Galaxy Clusters at Low Redshift
Authors: Chen Kaiyuan , Xu Weiwei , Jiang Linhua 
Published: November 2022

Abstract
We present MMT spectroscopic observations of two massive galaxy cluster candidates at redshift z ∼ 0.07 that show extended and diffuse X-ray emission in the ROSAT All-Sky Survey (RASS) images. The targets were selected from a previous catalog of 303 newly identified cluster candidates with the similar properties using the intracluster medium emission. Using the new MMT Hectospec data and Sloan Digital Sky Survey archival spectra, we identify a number of member galaxies for the two targets and confirm that they are galaxy clusters at z = 0.079 and 0.067, respectively. The size of the two clusters, calculated from the distribution of the member galaxies, is roughly 2 Mpc in radius. We estimate cluster masses using three methods based on their galaxy number overdensities, galaxy velocity dispersions, and X-ray emission. The overdensity-based masses are (6 ∼ 8) × 1014
M
⊙, comparable to the masses of large clusters at low redshift. The masses derived from velocity dispersions are significantly lower, likely due to their diffuse and low concentration features. Our result suggests the existence of a population of large clusters with very diffuse X-ray emission that has been missed by most previous searches using the RASS images. If most of the 303 candidates in the previous catalog are confirmed to be real clusters, this may help to reduce the discrepancy of cosmological results between the cosmic microwave background and galaxy cluster measurements.
Polarization Observations of a Split-band Type II Radio Burst from the Solar Corona
Authors: Ramesh R. , Kathiravan C. 
Published: November 2022

Abstract
Using temporal observations of circular polarized harmonic plasma emission from a split-band type II solar radio burst at 80 MHz, we separately estimated the coronal magnetic field strengths (B) associated with the lower (L) and upper (U) frequency bands of the burst. The corresponding Stokes I and V data were obtained with the polarimeter operating at the above frequency in the Gauribidanur observatory. The burst was associated with a flare/coronal mass ejection on the solar disk. Simultaneous spectral observations with the spectrograph there in the frequency range 80–35 MHz helped to establish that the observed polarized emission was from the harmonic component of the burst. The B values corresponding to the polarized emission from the L and U bands at 80 MHz are B

L
≈ 1.2 G and B

U
≈ 2.4 G, respectively. The different values of B for the observed harmonic emission at the same frequency (80 MHz) from the two bands imply unambiguously that the corresponding fundamental emission at 40 MHz must have originated at different spatial locations. Two-dimensional radio imaging observations of the burst with the radioheliograph in the same observatory at 80 MHz indicate the same. As comparatively higher B is expected behind a propagating shock due to compression as well as the corresponding coronal regions being closer to the Sun, our results indicate that the sources of L- and U-band emission should be located ahead of and behind the associated coronal shock, respectively. These are useful to understand the pre- and postshock corona as well as locations of electron acceleration in a propagating shock.
Des obligations des personnels réservistes à la frontière de leur statut de militaire et de civil : de la disponibilité et du devoir de réserve
Authors: Chaffard-Luçon Pierre 
Published: November 2022

Résumé Aux termes du Code de la défense, les réservistes n'ont la qualité de militaires que s'ils sont régulièrement convoqués par l'autorité compétente. Juridiquement, ils sont civils en dehors des périodes où ils sont convoqués et ne devraient alors pas être soumis aux obligations propres aux militaires. Or, la pratique témoigne de l'inverse : la « vie civile » des réservistes est prise en compte par les armées, tant lorsqu'elle fait honneur à l'institution que lorsqu'elle lui porte préjudice. Il s'agit dans cet article d'interroger les obligations pouvant peser sur ces personnels lorsque leurs statuts civil et militaire se rencontrent. Il apparaîtra sur la question de l'obligation de disponibilité et celle du devoir de réserve que la frontière n'est pas aussi marquée que l'affirme le Code : il arrive qu'en pratique les réservistes soient soumis dans leur vie civile à des contraintes propres au statut militaire. Ces contraintes peuvent conduire à des sanctions disciplinaires pour des faits survenus en dehors de toute période de réserve.
Les exportations d'armements et de matériels de guerre dans le Code de la défense : aspects juridiques
Authors: Trigeaud Laurent 
Published: November 2022

Résumé En 2019, trois recours furent déposés devant les juridictions administratives françaises par des ONG, visant le refus du Premier ministre de suspendre des exportations d'armements de guerre vers l'Arabie saoudite. Était invoquée la réglementation internationale encadrant le processus d'autorisation d'exportation, plus spécialement le Traité sur le commerce des armes de 2013, qui prohibe toute exportation dès lors que le matériel pourrait être utilisé à des fins contraires aux droits de l'homme ou au droit humanitaire. Ces contentieux mettent en lumière le régime français de transfert institué par le Code de la défense, et révèlent à ce titre un phénomène nouveau : la judiciarisation croissante des exportations d'armements.
La Consulaire. Du grand canon de la Régence turque d’Alger au monument de Brest
Authors: Le Goualher Jacques 
Published: November 2022

La Consulaire, grand canon de bronze du xvie siècle que les arabophones nomment Baba Merzoug, fut transférée en France en 1830, après la prise d’Alger par les français ; elle y est devenue la colonne d’un monument du port militaire de Brest. La médiatisation des demandes de sa restitution, à l’occasion du 50e anniversaire de l’indépendance de l’Algérie, en a fait un enjeu mémoriel entre les deux pays. Mais sa célébrité repose en partie sur des légendes et ses approches mémorielles sont diverses. Pour démêler histoire et légendes, il nous faut retourner aux sources et replacer la Consulaire et les événements qui font sa renommée dans leur contexte historique, qui mêle la naissance de l’artillerie moderne, les origines de la Régence ottomane d’Alger et ses relations avec la France, l’esclavage méditerranéen, l’hagiographie et la diplomatie. Nous pouvons ainsi rendre au dernier des grands basilics ottomans sa véritable origine et lui porter un regard plus lucide.
Quantitative results for the direct participation of the parenchymal vascular system in cerebral waste removal

Published: November 2022

Background: Impaired cerebral waste clearance (CWC) has been associated with a broad range of both physiological and pathophysiological neurologic conditions.1,2 Because of the unique anatomy of the brain parenchyma, theoretically, in the brain parenchyma, biochemically inert waste such as magnetic resonance imaging (MRI) contrast agents can only be removed through two possible pathways: cerebrospinal fluid (CSF) pathway, and/or vascular pathway. Despite the controversy, there seems to be a solid consensus on the participation of the CSF pathway in CWC.3 In contrast to the CSF system, the current consensus is that the parenchymal vascular system does not participate in CWC. Considering there is a big difference in flow rate between the blood (2 mL/min) and the CSF (3.7 µL/min) and the brain is the most bioactive, energy-consuming organ (20% nutrition for about 5% of body weight) in the body, it is illogical that the brain would rely on the slow CSF circulation for CWC while less bioactive tissues outside the brain require both the fast vascular and slow lymphatic systems to remove waste in a timely manner.4,5
Methods: Superparamagnetic iron oxide–enhanced susceptibility-weighted imaging (SPIO-SWI) and quantitative susceptibility mapping (QSM) methods were used to simultaneously study 7 T MRI signal changes in parenchymal veins, arteries, and their corresponding para-vascular spaces in 26 rats, following intra-cisterna magna (ICM) infusion of different CSF tracers (FeREX, ferumoxytol, Fe-Dextran) to determine the amount of tracer in the artery and vein quantitatively.
Results: The parenchymal venous system participated in CSF tracer clearance following ICM infusion of different MRI tracers with different concentrations of iron. Parenchymal venous participation was more obvious when 75 μg iron was injected. In the parenchymal veins, the relative mean (±SE) value of the susceptibility increased by 13.5±1.0% at 15 min post-tracer infusion (p<0.01), and 33.6±6.7% at 45 min post-tracer infusion (p=0.01), compared to baseline. In contrast to the parenchymal veins, a negligible amount of CSF tracer entered the parenchymal arteries: 1.3±2.6% at 15 min post-tracer infusion (p=0.6), and 12±19% at 45 min post-tracer infusion (p=0.5), compared to baseline.
Conclusions: MRI tracers can enter the parenchymal vascular system and more MRI tracers were observed in the cerebral venous than arterial vessels, suggesting the direct participation of parenchymal vascular system in CWC.

Authors: Vatsa Richa , Suri Vanita , Gainder Shalini , Arora Aashima , Kaur Japleen , Choudhary Neelam , Sharma Shruti 
Published: November 2022

Objective:
To detect effect of removing cervical mucus before performing intrauterine insemination (IUI) on pregnancy rate in patients with unexplained infertility.

Methods:
The randomized controlled trial was conducted in Infertility Division of Department of Obstetrics and Gynaecology of a tertiary care hospital. Totally 80 patients of unexplained infertility were recruited. By computer generated block randomization in block size of 4 and 6, patients were randomly allocated at time of starting ovarian stimulation into the cervical mucus removal group or the non-removal of cervical mucus group before IUI, 40 in each group. Ovarian stimulation with clomiphene 100 mg from day 2-6 of menstrual cycle along with human menopausal gonadotropin 150 IU was given alternate day starting from day 7. Follicular monitoring was done and further doses given as per response; trigger was planned when 1-3 follicle reach a diameter of >18 mm. IUI was planned after trigger. IUI was done as per the group allocated. Mucus cleaning was done in the cervical mucus removal group by aspirating mucus with IUI syringe and sterile cotton swab before IUI. The primary outcome was clinical pregnancy rate. Number of difficult IUIs and cycle cancellation due to ovarian hyperstimulation were also noted.

Results:
IUI was not done in 4 patients due to hyperstimulation. Pregnancies per IUI cycle occurred in 7.9% (3/38) in the cervical mucus removal group and 21.1% (8/38) in the non-removal of cervical mucus group. There was no statistically significant difference in clinical pregnancy rate between two groups (P=0.19).

Conclusions:
There is a trend towards a lower clinical pregnancy rate with removal of cervical mucus before IUI in women of unexplained infertility though the difference is not statistically significant. Further studies with large sample size need to be done on this intervention.

Trial registration:
The trial registration was done with Clinical Trial Registry-India (Registration number: CTRI/2019/03/018326).
Do the Covid-19 vaccines affect the reproductive parameters of men?—A Northern Saudi experience
Authors: Alenzi MJ , Ikpi EE , Alshlash AS , Alkhaldi SM , Aljazi ZN , Alrawili M , Alanazi S , Alenazi JA 
Published: November 2022

Background:
The COVID-19 vaccine acceptance is a psychological behavior influenced by many factors, including fear of an adverse effect on the reproductive system.

Aims:
The aim of this study is to assess the COVID-19 vaccines effect on reproductive parameters among the male population of northern Saudi Arabia.

Patients and Methods:
We conducted a prospective cohort study among 100 volunteers who received two doses of COVID-19 vaccines. A pre- and post-vaccination blood sample was collected and analyzed for testosterone, prolactin, and follicle-stimulating hormone (FSH). Semen samples were also collected and analyzed. The Wilcoxon signed-rank test was used to compare the values between pre- and post-vaccination.

Results:
Of the 100 samples analyzed, there was a significant increase in progressive sperm motility after the second dose of vaccination, but the increase was within the physiological limits (pre-55.03 [42.00–61.75] vs. post-57.50 [42.25–63.00], P = 0.008). Similarly, a significant increase in serum testosterone level after the second vaccination dose was observed (pre-380.65 [301.60–485.73] vs. post-410 [318.18–505.35], P = 0.016).

Conclusion:
These preliminary results show that the COVID-19 vaccines do not have any adverse effect on the reproductive parameters of men. A prospective long-term follow-up study will be necessary on all WHO -approved COVID vaccines to determine their long-term effect on men's reproductive health. The future follow-up study could strengthen our findings and encourage the men who have vaccine hesitancy to take due to fear of its effect on reproductive parameters.

Published: November 2022

Background:
Although COVID-19 has a milder course in pediatric patients than in adults, it can have a severe and fatal course in children with an underlying disease (UD).

Aims:
In this study, we aimed to evaluate the demographic, clinical, laboratory, and radiological characteristics, treatment methods, and prognosis of pediatric patients diagnosed with COVID-19.

Patients and Methods:
The files of patients aged 0–18 years diagnosed with COVID-19 were retrospectively evaluated. Clinically and radiologically suspicious cases were accepted as confirmed cases if SARS-CoV-2 PCR positivity was found in nasopharyngeal swab samples. The severity of the disease was defined as asymptomatic, mild, moderate, and severe according to clinical, laboratory, and radiological features.

Results:
A total of 322 pediatric patients, 51.2% male and 48.8% female, were included in the study. The median age of the patients was 12.08 years (1 month–18 years). Of the 322 patients, 81 (25.1%) were asymptomatic. Disease severity was as follows: 218 were (67.7%) mild, 14 were (4.3%) moderate, and 9 (2.7%) were severe. 35.7% of the patients were hospitalized. Six percent were admitted to the intensive care unit, and three (0.93%) patients died. The mortality rate in patients with the UD was 3.3%.

Conclusion:
In our study, we determined that the disease had a more severe course in patients with initial procalcitonin, D-dimer, troponin increase, and thrombocytopenia. Although COVID-19 has a mild course in children, this is unfortunately not true for children with an UD.
