Modified Path-conservative HLLEM Scheme for Magnetohydrodynamic Solar Wind Simulations

Published: March 2021

Abstract
The goal of the present work is to solve the magnetohydrodynamic (MHD) system of extended generalized Lagrange multiplier (EGLM) formulation with Galilean invariance (G-EGLM MHD equations) through a modified path-conservative HLLEM finite-volume method. A second-order least-squares reconstruction with Venkatakrishnan limiter is employed for state variables, and a solenoidality-preserving condition is considered for the magnetic field with the purpose of magnetic divergence cleaning. The two-stage Runge–Kutta time-integration method is utilized to advance the MHD governing equations. Compared with the original path-conservative HLLEM method, the modified method in this paper is shock stable and is able to adjust the diffusion according to the smoothness of the physical flow so as to automatically apply more diffusion near strong shocks and less in smooth regions near rarefaction waves and at contact discontinuities. Meanwhile, it can be robustly defined in the low plasma-β region. After several tests of smooth Alfvén wave, strong Lax, odd–even perturbation, and blast-wave problems, the large-scale structures of the solar corona for Carrington Rotation 2185 are numerically modeled in a six-component grid system of spherical coordinates with input from a Carrington rotation synoptic map provided by the Helioseismic and Magnetic Imager. Numerical results show the model’s capability of producing a structured solar wind in agreement with the observations.
Data-driven Spectroscopic Estimates of Absolute Magnitude, Distance, and Binarity: Method and Catalog of 16,002 O- and B-type Stars from LAMOST

Abstract
We present a data-driven method to estimate absolute magnitudes for O- and B-type stars from the LAMOST spectra, which we combine with Gaia DR2 parallaxes to infer distance and binarity. The method applies a neural network model trained on stars with precise Gaia parallax to the spectra and predicts K
s-band absolute magnitudes

with a precision of 0.25 mag, which corresponds to a precision of 12% in spectroscopic distance. For distant stars (e.g., >5 kpc), the inclusion of constraints from spectroscopic

significantly improves the distance estimates compared to inferences from Gaia parallax alone. Our method accommodates for emission-line stars by first identifying them via principal component analysis reconstructions and then treating them separately for the

estimation. We also take into account unresolved binary/multiple stars, which we identify through deviations in the spectroscopic

from the geometric

inferred from Gaia parallax. This method of binary identification is particularly efficient for unresolved binaries with near equal-mass components and thus provides a useful supplementary way to identify unresolved binary or multiple-star systems. We present a catalog of spectroscopic

, extinction, distance, flags for emission lines, and binary classification for 16,002 OB stars from LAMOST DR5. As an illustration, we investigate the

of the enigmatic LB-1 system, which Liu et al. had argued consists of a B star and a massive stellar-mass black hole. Our results suggest that LB-1 is a binary system that contains two luminous stars with comparable brightness, and the result is further supported by parallax from the Gaia eDR3.

Published: March 2021

Abstract
We have used the Large Sky Area Multi-Object Fibre Spectroscopic Telescope (LAMOST) low-resolution and medium-resolution spectroscopic surveys to explore the chromospheric statistical properties and variations of M stars. There are 738,477 LAMOST low-resolution spectra of 622,523 M stars. We have calculated equivalent widths of the Ca ii H&K, Hα, Hβ, Hγ, Hδ, He i D3, and Ca ii infrared triplet lines. Based on the Hα EWs, we found that 33,374 objects showed Hα emissions. We revised the relationship between the active fraction and spectral subtype, and confirmed that the active fractions increased from M0 to M3, and possibly declined from M4 to subsequent types. Among 86,005 objects with repeated spectra, 19,422 objects showed Hα variations. The variation fraction of stars with M4 and subsequent types with a fully convective envelope was higher than those of M0–M3 with a partially convective envelope. By combining the distances from Gaia, we have determined the positions of the M dwarfs in the catalog for M stars. The active fraction decreased rapidly in the height range of 0–400 pc above and below the Galactic plane, and maintained a steady trend in 400–1000 pc. We cross-matched the M catalog of the LAMOST low-resolution survey with LAMOST medium-resolution spectra. We obtained 272,181 spectra of 13,355 M objects and calculated the Hα EWs. Among them, 3813 stars show variations, which might be caused by chromospheric activity evolution with orbital phase or time. The Hα emission for 972 objects shows variations over short and long timescales, especially on short timescales of 20 minutes.
Transformations du territoire esthétique : « créer en mapuche » dans l’institution théâtrale chilienne
Authors: Rostollan-Sinet Corentin 
Published: March 2021

Nourri par trois ans d’enquête sur les festivals de théâtre chiliens, cet article s’intéresse aux créations de Paula González Seguel et Ricardo Curaqueo Curiche, et au geste politique opéré par ces deux artistes indigènes travaillant « en mapuche » dans l’institution culturelle nationale chilienne. Comment ces créations scéniques depuis l’être-indigène, depuis un être-mapuche aux (re)définitions diverses, offrent-elles de nouvelles options pour la construction d’une communauté politique pluriculturelle future ?Aujourd’hui plus que jamais se fait nécessaire la représentativité indigène dans le processus d’élaboration d’une nouvelle Constitution. À l’heure où s’envisage enfin la possibilité d’un État plurinational, notre article questionne l’opérativité politique d’une récupération des territoires esthétiques, et celle d’une approche de la culture, de ses produits et de ses espaces comme autant de territoires d’interculturalité à réconcilier avec le dissensus et le conflit.
Teatro x la Identidad : itinéraire d’un théâtre militant, du combat des Abuelas de Plaza de Mayo à la croisée des émancipations
Authors: Sanchez Joana 
Published: March 2021

Teatro x la Identidad est un mouvement théâtral impulsé en 2000 en Argentine par les Abuelas de Plaza de Mayo, dans le cadre de leur combat pour retrouver leurs petits-enfants nés dans les geôles de la dictature entre 1976 et 1983 et « appropriés » (ou « volés », selon l’expression consacrée) par les militaires. Ces enfants adoptés illégalement et méconnaissant leurs origines ont une vingtaine d’années au tournant des années 2000, si bien que les Abuelas, dans un virage stratégique, décident de s’adresser directement à la jeune génération pour inciter tous ceux qui auraient le moindre doute sur leur ascendance à venir effectuer des tests ADN, seule manière de dévoiler l’appropriation et l’usurpation d’identité. Pour ce faire, elles se tournent vers le milieu théâtral et entreprennent une collaboration appelée à durer puisque le cycle Teatro x la Identidad a lieu chaque année depuis maintenant presque vingt ans. Il marque, en Argentine, le renouveau d’un théâtre de combat, au service d’une cause politique et mémorielle, renouant avec le militantisme qui avait caractérisé certaines dramaturgies des années 1960 et 1970. Or si certaines pièces écrites pour le cycle sont strictement orientées vers la question de l’appropriation d’enfants pendant la dictature militaire, les dramaturges conjuguent parfois cette question à une réflexion plus large sur l’identité et ses enjeux : les appartenances imposées, les identités assignées, les processus d’acculturation et d’assimilation, la complexité de la définition de soi, les différents rapports de domination qui traversent une société et les individus, et participent à la construction identitaire de soi. Une réflexion sur les rapports sociaux de genre, de classe, mais aussi de race, dans un pays où le mythe de « l’Argentine blanche » est encore très prégnant et peut freiner le travail décolonial, se fait ainsi jour sur les planches des cycles Teatro x la Identidad. En ce sens, cet article analyse comment ce théâtre militant, conçu comme un outil au service d’une lutte très particulière, a aussi replacé ce combat singulier à la croisée de luttes pour l’émancipation, dans une démarche intersectionnelle, qui fait de l’identité son pivot articulatoire.
Un parti de la loi et de l’ordre aux États-Unis ? Essai généalogique et historiographique
Authors: Philippe Yann 
Published: March 2021

Comment la sécurité peut-elle être définie aux États-Unis à la fois comme un thème privilégié de la droite et comme une question consensuelle traversant l’échiquier politique ? Afin de répondre à cette question, cet article propose un bilan historiographique permettant de dépasser le paradigme de la polarisation. La mise au jour des sources de l’idéologie sécuritaire contemporaine permet de comprendre comment la politisation de la loi et de l’ordre a contribué à la fois à la résurgence du parti républicain et à la recomposition du paysage politique depuis la Seconde Guerre mondiale.
Vers une restauration scientifique des textiles anciens (xixe-xxe siècles)
Authors: Privat-Savigny Maria-Anne 
Published: March 2021

Retracer l’histoire de la restauration des textiles anciens est une entreprise complexe, car les interventions, dont l’objectif a longtemps consisté à prolonger la vie et l’usage de ces étoffes, sont rarement documentées. Les archives certes, mais surtout l’observation des interventions anciennes constituent des sources précieuses d’information qui permettent de dégager trois temps vers une approche scientifique de la restauration des textiles anciens : d’abord la prise de conscience de leur importance historique et la mise en place de procédés, à la fin du xixe siècle, époque où les textiles archéologiques et médiévaux ont passionné les spécialistes, amateurs et collectionneurs ; ensuite, dès les premières années du xxe siècle, l’élaboration d’une méthodologie dont certains principes sont énoncés dans l’enquête menée au cours des années 1930 par l’Office international des musées auprès des principaux responsables de collections de tissus dans le monde ; enfin, dans les années qui suivent la fin de la Seconde Guerre mondiale, les bases de la restauration scientifique de ces œuvres sont posées tandis qu’apparaissent les principaux ateliers de restauration européens.

Published: March 2021

Background:
Central venous access is usually preferred over the peripheral venous route when circulatory failure needs inotropes and vasopressors. However, in resource-limited settings with underskilled personnel, it is not feasible always and so patients are being treated with the peripheral venous route with variable results. We aimed to compare external jugular venous (EJV) access with internal jugular venous (IJV) access for effectiveness, ease of procedure, complications, and treatment cost in pediatric shock.

Subjects and Methods:
This was a prospective, nonrandomized, observational study from January 2014 to June 2015 in 66 pediatric patients with shock at a 7-bedded pediatric intensive care unit. Parents were explained about both routes. Depending on their affordability and consent, one route was chosen. Pertinent data were obtained, and analysis was done as per objectives.

Results:
EJV and IJV had 50 and 16 patients, respectively. Baseline characteristics were comparable. Death and discharge against medical advice rates are high in both the groups. No procedure-related life-threatening complications in any group and local site problems were similar in both the groups. Overall attempts and duration of procedure were similar in both the groups, and although the initial cost of the procedure of the IJV group was higher, overall final hospital bill had no significant difference. The median (Q1, Q3) hours of achieving shock-free status were 48 (24, 96) and 46 (12, 108) (P = 0.412). The median (Q1, Q3) improvement in base deficit at the end of 24 h was −4.5 (−8.1, 0.27) and −1.9 (−4.2, −0.6) (P = 0.259) in the EJV and IJV groups, respectively.

Conclusion:
For pediatric shock management, EJV access is an effective, easy, and cost economic procedure without significant complications as compared to IJV access.

Published: March 2021

Cold sensation (CS) is a cold feeling on people’s hands or feet; this is a well-known health problem for young females. Plantar tactile sensation plays an important role in postural control and is affected by skin temperature. However, there is no research focusing on the relation between CS and plantar tactile sensation. In this study, we address the question of whether the CS influences plantar tactile sensation. 32 non cold sensation (Non-CS) and 31 cold sensation (CS) young females have participated in this research. A tactile sensation test was conducted at five plantar points (first and fifth toes, first and fifth metatarsal heads, and heel). Experimental results showed that although there was no significant difference at the first and fifth toes as well as the first metatarsal head and heel, the sensation threshold at the fifth metatarsal head for CS was lower than the Non-CS (21.61 ± 8.10 μm, 27.42 ± 11.02 μm respectively, p < 0.05). It was concluded that plantar tactile sensation for young females with cold sensation was more sensitive compared to healthy subjects.

Published: March 2021

Second wave of the new coronavirus (SARS-CoV-2) has been declared throughout the world. It has been always thought that children are the least affected group. A new childhood disease, referred to as MIS-C (Multisystem Inflammation Syndrome) or PIMS-TS (Pediatric Inflammatory Multiorgan Syndrome Temporally related to SARS-CoV-2) was first recognized in April 2020. Shock and multiorgan failure affected some of those children that required intensive care; others were clinically similar to Kawasaki disease or toxic shock. The clinical evidence suggests that this inflammatory multisystem syndrome is temporally associated with severe acute respiratory syndrome corona virus 2. Many clinical uncertainties regarding this new disease rapidly became apparent in prevalence, clinical phenotypes, variable severity, clinical course, and optimal management. We aim to increase awareness of this syndrome regarding the diagnosis and management of children with suspected PIMS-TS by presenting two clinical cases and illustrating the available medical literature in regards to establishing the diagnosis and the appropriate therapeutic interventions. SARS-Cov-2 related medical impacts on children seem not well clarified yet. When a PIMS-TS case is suspected then full investigations should be done, children who have persistent fever associated with abdominal pain, diarrhea ,vomiting ,cough, neurologic symptoms should have primary blood tests to identify PIMS-TS: full blood count, CRP: C-reactive protein, BUN: Blood Urea Nitrogen, Cr: Creatinine, Electrolytes and liver function. Multidisciplinary team approach seems mandatory from the very beginning. Despite the use of IVIG in the treatment of all diagnosed cases, steroids in regular doses could be a good alternative and requires further investigative evaluations.

Published: March 2021

Background: Attitude towards mental illness influence the nursing students’ choice to take up training and placement in psychiatry as a specialty. The aim of the study was to examine nursing students' attitudes towards mental illness in terms of aetiology, social relations with patients and self-disclosure regarding mental illness.
Methods: This was a descriptive quasi-experimental study conducted among all the sixty nursing students attending a 6-week psychiatry posting at Federal Neuropsychiatry Hospital Kware, Sokoto State and Psychiatry unit of General Hospital Katsina, Northwest Nigeria in July 2018. Attitudes toward Mental Illness (ATMI), a self-administered questionnaire was given to the participants before and after six-week posting in psychiatry. Data was analyzed using SPSS version 23.
Results: After 6 weeks posting in psychiatry there was improvement in the participants’ positive attitude towards social relation in person with mental illness, willingness to self-disclosure regarding mental illness and etiology of mental illness compare to before the commencement of psychiatry posting. Majority (81%) reported that movies have negative influence on their attitude toward mental illness.
Conclusion: The 6-week psychiatry posting has positive effects on nursing students' attitudes towards mental illness. Movies contribute negatively towards majority of the participants’ attitude to mental illness. Use of psychodrama is being suggested to educate people on the etiology and treatment of mental illness. This study provides evidence-based recommendation for mandatory psychiatry posting among other health workers under training and use of psychodrama to educate the public on mental illness.

Published: March 2021

This research is motivated by the character program launched by the Indonesian government which has not been carried out well. Even though Indonesia has Pancasila values which are extracted from the Indonesian culture. So that Indonesia needs to reflect on the Japanese country which has succeeded in building the character of its nation. This study aims to compare the core ethical values of Indonesia and Japan based on the country's philosophy from a historical perspective. The research method used is a literature study with a descriptive qualitative approach. The results showed that the core ethical values of the Japanese nation were more consistent, detailed and with serious government support, were more successful than the application of core ethical values in Indonesia. Although the origin of the core ethical values of the Japanese people is not from their ancestral culture the result of concern and awareness of the backwardness of other nations in 1860, while Indonesia has the most beautiful gifts, core ethical values are a legacy from our ancestors of former glory which is summarized in the form of Pancasila. Even though the implementation in the life of the nation and state is not yet optimal, so it does not contribute to the maximum national development process
