Another Look at Erupting Minifilaments at the Base of Solar X-Ray Polar Coronal “Standard” and “Blowout” Jets
Authors: Sterling Alphonse C. , Moore Ronald L. , Panesar Navdeep K. 
Published: March 2022

Abstract
We examine 21 solar polar coronal jets that we identify in soft X-ray images obtained from the Hinode/X-ray telescope (XRT). We identify 11 of these as blowout jets and four as standard jets (with six uncertain), based on their X-ray-spire widths being respectively wide or narrow (compared to the jet’s base) in the XRT images. From corresponding extreme ultraviolet (EUV) images from the Solar Dynamics Observatory’s (SDO) Atmospheric Imaging Assembly (AIA), essentially all (at least 20 of 21) of the jets are made by minifilament eruptions, consistent with other recent studies. Here, we examine the detailed nature of the erupting minifilaments (EMFs) in the jet bases. Wide-spire (“blowout”) jets often have ejective EMFs, but sometimes they instead have an EMF that is mostly confined to the jet’s base rather than ejected. We also demonstrate that narrow-spire (“standard”) jets can have either a confined EMF, or a partially confined EMF where some of the cool minifilament leaks into the jet’s spire. Regarding EMF visibility: we find that in some cases the minifilament is apparent in as few as one of the four EUV channels we examined, being essentially invisible in the other channels; thus, it is necessary to examine images from multiple EUV channels before concluding that a jet does not have an EMF at its base. The sizes of the EMFs, measured projected against the sky and early in their eruption, is 14″ ± 7″, which is within a factor of 2 of other measured sizes of coronal-jet EMFs.
Application of a Steady-state Accretion Disk Model to Spectrophotometry and High-resolution Spectra of Two Recent FU Ori Outbursts
Authors: Rodriguez Antonio C. , Hillenbrand Lynne A. 
Published: March 2022

Abstract
We apply a conventional accretion disk model to the FU Ori–type objects HBC 722 and Gaia 17bpi. Our base model is a steady-state, thin Keplerian disk featuring a modified Shakura–Sunyaev temperature profile, with each annulus radiating as an area-weighted spectrum given by a NextGen atmosphere at the appropriate temperature. We explore departures from the standard model by altering the temperature distribution in the innermost region of the disk to account for “boundary region”–like effects. We consider the overall spectral energy distribution as well as medium- and high-resolution spectra in evaluating best-fit models to the data. Parameter degeneracies are studied via a Markov Chain Monte Carlo parameter estimation technique. Allowing all parameters to vary, we find accretion rates for HBC 722 of

Alternate models that fix some disk or stellar parameters are also presented, with tighter confidence intervals on the remaining fitted parameters. In order to improve upon the somewhat large credible intervals for the

Recent Formation of a Spiral Disk Hosting Progenitor Globular Clusters at the Center of the Perseus Brightest Cluster Galaxy. II. Progenitor Globular Clusters
Authors: Lim Jeremy , Wong Emily , Ohyama Youichi , Yeung Michael C. H. 
Published: March 2022

Abstract
We address the nature and origin of super star clusters (SSCs) discovered by Holtzman et al. within a radius of ∼5 kpc from the center of NGC 1275, the giant elliptical galaxy at the center of the Perseus Cluster. We show that, in contrast with the much more numerous population of SSCs subsequently discovered up to ∼30 kpc from the center of this galaxy, the central SSC population have maximal masses an order of magnitude higher and a mass function with a shallower power-law slope. Furthermore, whereas the outer SSC population have ages spanning a few Myr to at least ∼1 Gyr, the central SSC population have ages strongly concentrated around ∼500 Myr with a 1σ dispersion of ∼100 Myr. These SSCs share a close spatial and temporal relationship with the “central spiral,” which also has a radius ∼5 kpc centered on NGC 1275 and a characteristic stellar age of ∼150 Myr. We argue that both the central SSC population and the central spiral formed from gas deposited by a residual cooling flow, with the SSCs forming first followed by the formation of the stellar body of the central spiral ∼300–400 Myr later. The ages of the central SSC population imply that they are able to withstand very strong tidal fields near the center of NGC 1275, making them genuine progenitor globular clusters. Evidently, a spiral disk hosting progenitor globular clusters has recently formed at the center of a giant elliptical galaxy.

Abstract
The bulk chemical composition and interior structure of rocky exoplanets are fundamentally important to understand their long-term evolution and potential habitability. Observations of the chemical compositions of solar system rocky bodies and of other planetary systems have increasingly shown a concordant picture that the chemical composition of rocky planets reflects that of their host stars for refractory elements, whereas this expression breaks down for volatiles. This behavior is explained by devolatilization during planetary formation and early evolution. Here we apply a devolatilization model calibrated with solar system bodies to the chemical composition of our nearest Sun-like stars—α Centauri A and B—to estimate the bulk composition of any habitable-zone rocky planet in this binary system (“α-Cen-Earth”). Through further modeling of likely planetary interiors and early atmospheres, we find that, compared to Earth, such a planet is expected to have (i) a reduced (primitive) mantle that is similarly dominated by silicates, albeit enriched in carbon-bearing species (graphite/diamond); (ii) a slightly larger iron core, with a core mass fraction of

wt% (see Earth’s 32.5 ± 0.3 wt%); (iii) an equivalent water-storage capacity; and (iv) a CO2–CH4–H2O-dominated early atmosphere that resembles that of Archean Earth. Further taking into account its ∼25% lower intrinsic radiogenic heating from long-lived radionuclides, an ancient α-Cen-Earth (∼1.5–2.5 Gyr older than Earth) is expected to have less efficient mantle convection and planetary resurfacing, with a potentially prolonged history of stagnant-lid regimes.

Abstract
We use data from the first six encounters of the Parker Solar Probe and employ the partial variance of increments (PVI) method to study the statistical properties of coherent structures in the inner heliosphere with the aim of exploring physical connections between magnetic field intermittency and observable consequences such as plasma heating and turbulence dissipation. Our results support proton heating localized in the vicinity of, and strongly correlated with, magnetic structures characterized by PVI ≥ 1. We show that, on average, such events constitute ≈19% of the data set, though variations may occur depending on the plasma parameters. We show that the waiting time distribution (WT) of identified events is consistent across all six encounters following a power-law scaling at lower WTs. This result indicates that coherent structures are not evenly distributed in the solar wind but rather tend to be tightly correlated and form clusters. We observe that the strongest magnetic discontinuities, PVI ≥ 6, usually associated with reconnection exhausts, are sites where magnetic energy is locally dissipated in proton heating and are associated with the most abrupt changes in proton temperature. However, due to the scarcity of such events, their relative contribution to energy dissipation is minor. Taking clustering effects into consideration, we show that smaller scale, more frequent structures with PVI between 1 ≲ PVI ≲ 6 play a major role in magnetic energy dissipation. The number density of such events is strongly associated with the global solar wind temperature, with denser intervals being associated with higher T

Abstract
We report the combined results of eight searches for strong gravitational lens systems in the full 5000 square degrees of Dark Energy Survey (DES) observations. The observations accumulated by the end of the third observing season fully covered the DES footprint in five filters (grizY), with an i-band limiting magnitude (at 10σ) of 23.44. In four searches, a list of potential candidates was identified using a color and magnitude selection from the object catalogs created from the first three observing seasons. Three other searches were conducted at the locations of previously identified galaxy clusters. Cutout images of potential candidates were then visually scanned using an object viewer. An additional set of candidates came from a data-quality check of a subset of the color–coadd tiles created from the full DES six-season data set. A short list of the most promising strong-lens candidates was then numerically ranked according to whether or not we judged them to be bona fide strong gravitational lens systems. These searches discovered a diverse set of 247 strong-lens candidate systems, of which 81 are identified for the first time. We provide the coordinates, magnitudes, and photometric properties of the lens and source objects, and an estimate of the Einstein radius for 81 new systems and 166 previously reported systems. This catalog will be of use for selecting interesting systems for detailed follow up, studies of galaxy cluster and group mass profiles, as well as a training/validation set for automated strong-lens searches.
Photometric Recalibration of the SDSS Stripe 82 to a Few Millimagnitude Precision with the Stellar Color Regression Method and Gaia EDR3
Authors: Huang Bowen , Yuan Haibo 
Published: March 2022

Abstract
By combining spectroscopic data from the LAMOST DR7, Sloan Digital Sky Survey (SDSS) DR12, and corrected photometric data from the Gaia EDR3, we apply the stellar color regression (SCR) method to recalibrate the SDSS Stripe 82 standard stars catalog of Ivezić et al. With a total number of about 30,000 spectroscopically targeted stars, we have mapped out the relatively large and strongly correlated photometric zero-point errors present in the catalog, ∼2.5% in the u band and ∼1% in the griz bands. Our study also confirms some small but significant magnitude dependence errors in the z band for some charge-coupled devices. Various tests show that we have achieved an internal precision of about 5 mmag in the u band and about 2 mmag in the griz bands, which is about five times better than previous results. We also apply the method to the latest version of the catalog (v4.2), and find modest systematic calibration errors of up to ∼1% along the R.A. direction and smaller errors along the decl. direction. The results demonstrate the power of the SCR method when combining spectroscopic data and Gaia photometry in breaking the 1% precision barrier of ground-based photometric surveys. Our work paves the way for the recalibration of the whole SDSS photometric survey and has important implications for the calibration of future surveys. Future implementations and improvements of the SCR method under different situations are also discussed.

Published: March 2022

Background: The delay in cognitive and language development can be caused by multifactor, including chronic deficiency of micronutrient, zinc. Level of zinc serum is influenced by food intake which can cause bias. There are inconsistencies in previous studies between zinc levels and the development caused by differences of sample or subjects. This study using hair as sample in analyzing the association between zinc level on cognitive and language delays in children aged 9-24 months old. AIM: To find out that low hair zinc level is associated with delayed of cognitive and language development in children 9-24 months old. Method: This analytical observational study with case-control design. Case group consisted of 69 children with cognitive and language development delays, based on CAT/CLAMS scores < 85 subjects aged 9-24 months meanwhile the control group consist of 69 children with normal cognitive and language development. Chi-square test was used to assess the association between zinc levels and the incidence of cognitive and language delays. Multivariate analysis was performed by logistic regression. Results: Univariate analysis showed no association between low zinc level and delayed of cognitive and language development in children aged 9-24 months (OR 1.263; 95% CI 0.64-2.46; p=0.495). Logistic regression was performed for other variables and screen time > 2 hours and lack of stimulation were risk factors for cognitive and language development delays (adjusted OR 2.78; 95% CI 1,284-6.058; p=0.010 and adjusted OR 3.96; 95% CI 1.833-8.581; p<0.001). Conclusion: There is no relationship between low hair zinc level and delays in cognitive and language development in children age 9-24 months, but there is an association between screen time more than two hours per day and lack of stimulation with delays in cognitive and language development in children 9-24 months 24 months.

Published: March 2022

BACKGROUND: Prediabetes itself could be an independent predictor of such adverse cardiovascular events as myocardial infarction and ischemic stroke. Since prediabetes is linked with hyperinsulinism it could also cause fluctuations of incretins concentration. Another significant fact related to prediabetes is glycemic variability. The impact of these factors on prediabetes and acute myocardial infarction is a promising phenomenon to study.
AIM: The study aims to estimate insulin, incretins, and glycemic variability in patients with impaired carbohydrate metabolism and acute myocardial infarction
METHODS: The 255 prediabetes patients participated in the observational case-control study. The first group included 85 patients hospitalized for STEMI. The second group included 170 patients without STEMI. Insulin and incretins were measured using a multiplex immunological assay with XMap technology on Bioplex 3D. The high-performance liquid chromatography with mass spectrometry was used to evaluate 1,5-AG concentration. The binary logistic regression was performed to evaluate the association between studying parameters and STEMI.
RESULTS: The insulin secretion parameters showed higher insulin and C-peptide level in patients with STEMI. A similar trend was noted for the HOMA-IR index. Among incretin, we revealed a higher level of glucagon and reduced GLP-1 in patients with STEMI. The of 1,5-AG in STEMI patients was significantly lower than in non-STEMI patients. The logistic regression model shows that a lower plasma concentration of 1,5-AG increases the odds of STEMI in patients with prediabetes [OR 2.304 (95% CI 1.980–2.973), p = 0.018]. Reduced GLP-1 concentration also increased the odds of STEMI [OR 1.775 (95% CI 1.460-1.990), p = 0.001].
CONCLUSION: We discovered the association between 1,5-AG, GLP-1, and STEMI in patients with prediabetes. It is designating their potential role as cardiovascular risk markers in non-diabetic patients with impaired glucose metabolism.
Colonialisme vert et transition énergétique au Mexique : la face cachée de l’extractivisme et du renouvelable industriel
Authors: S. Contreras Josefa , Altamirano Norberto , Stop EDF Mexique  
Published: March 2022

Au cours de l’été 2021, le collectif « Stop EDF Mexique » invitait des militant·es de l’isthme de Tehuantepec (Mexique) pour une tournée en France, afin de présenter leurs luttes contre les mégaprojets imposés par EDF sur leurs territoires. Ces rencontres visaient à rendre visible un colonialisme énergétique, inhérent aux processus de transition écologique lorsque ceux-ci s’inscrivent dans une logique productiviste. Le premier texte, proposé par le collectif Stop EDF Mexique, revient sur la rencontre entre les acteurs·trices de la lutte locale et les militant·es européen·nes. Dans les deux textes suivants, Josefa S. Contreras éclaire les formes de violence postcoloniale et les violations des droits humains qui sont perpétrées au nom de la transition énergétique, dans les communautés riveraines des projets portés par EDF. Enfin, Norberto Altamirano Zarate propose une réflexion sur la manière dont ces implantations industrielles fracturent les communautés concernées, en venant rompre les usages communaux qui pouvaient prévaloir jusqu’alors.
Militant·es climat, jeunes cheminots et vieux fourneaux de l’environnement : une convergence contre la casse du fret ferroviaire au Pays Basque

Published: March 2022

En 2009, la suppression de 300 emplois dans le fret ferroviaire au Pays Basque provoque une convergence inédite entre cheminots, défenseur·ses de l’environnement et militant·es climat abertzale 1 . En parallèle au projet de ligne à grande vitesse (LGV) entre Bordeaux et l’Espagne, la SNCF liquide les terminaux de fret et promeut la construction d’une autoroute ferroviaire, qui utilise des trains spéciaux pour transporter des poids lourds sur de grandes distances. Face à ce grand projet imposé, écolos et cheminots défendent un autre modèle ferroviaire fondé sur le transport par wagons isolés, qui permet de constituer des trains complets à partir de wagons seuls en utilisant toute la capillarité du réseau ferroviaire pour réduire au maximum l’utilisation des camions. La SNCF a malgré tout maintenu sa politique de fret désastreuse. C’est au final une petite mobilisation, mais qui a suscité une grande convergence autour de la défense du train comme mode de transport de marchandises le plus écologique. Les barrières qui existaient entre cheminots et écolos ont laissé la place à des liens de solidarité qui se sont renforcés avec les années.
Victoria aux portes de Thèbes : trauma, énigme et jeu

Published: March 2022

Nous proposons le récit clinique de la rencontre d’un psychiatre en formation avec une patiente psychotraumatisée qui présente une attitude énigmatique. Nous abordons les obstacles qu’une telle attitude impose à la démarche diagnostique et thérapeutique. Il en découle une réflexion à propos d’une psychothérapie dont le moteur est l’énigme et qui dégage trois dimensions fondamentales de la relation entre la patiente et le clinicien : la proximité, la corecherche et le jeu. Ce travail met ainsi en lumière une attitude psychothérapeutique qui va à l’encontre de l’application d’un processus de soins établi à l’avance, pour s’ouvrir à des dimensions qui émergeront au cours de la rencontre 1 .
Ports de signes religieux, « discrimination croisée » et ingérence de l’État dans la liberté de manifester sa religion
Authors: Tigroudja Hélène 
Published: March 2022

En 2018, le Comité des droits de l’homme des Nations Unies a rendu des constatations dans trois communications individuelles contre la France et la Turquie qui l’ont conduit, dans des contextes et pour des faits différents, à se prononcer sur la compatibilité entre l’interdiction de ports de signes religieux et la liberté de manifester sa religion au travail, à l’Université ou dans l’espace public (art. 18 du Pacte international relatif aux droits civils et politiques). Si sa position n’est guère surprenante au regard de son interprétation classique de la disposition, son approche « intersectionnelle »/« croisée » de la discrimination interdite à l’article 26 du Pacte l’est davantage. Les trois décisions sont en contradiction avec la jurisprudence de la Cour européenne, mais si cet élément n’est pas, en lui-même, critiquable, les failles dans le raisonnement et la motivation du Comité le sont plus, surtout eu égard à l’enjeu des questions soulevées.
Le rôle des femmes dans le combat : arme secrète du chef militaire de demain ?
Authors: Joyeux Karine 
Published: March 2022

Plusieurs exemples illustrent la possibilité d’engager des femmes au feu en misant spécifiquement sur certaines de leurs qualités « de genre ». L’exemple de la résistance durant la seconde guerre mondiale prouverait que l’engagement des femmes dans l’action violente se fait « en réaction », au vu de l’ampleur du péril et de la grandeur de la cause défendue. Prendre en compte « le déclencheur » qui actionne l’engagement féminin peut constituer un atout stratégique, en ouvrant opportunément le recrutement à un nouveau vivier comme ce fut le cas récemment en Ukraine ou au Kurdistan. Une fois engagées, les femmes renforceraient leur conviction première d’un réflexe de défi, source d’exemplarité et de dépassement de soi, qui en font la plupart du temps des combattantes reconnues de leurs pairs. La question se pose de savoir si les femmes au combat ne cultivent pas une prévenance naturelle vis-à-vis de leurs camarades qui en fait des médiateurs utiles au sein du groupe et des ailiers fiables, vigilants, souvent de bon conseil car abordant les questions tactiques avec un regard décalé.
