Ultra-short-period Planets Are Stable against Tidal Inspiral
Authors: Hamer Jacob H. , Schlaufman Kevin C. 
Published: August 2020

Abstract
It has been unambiguously shown both in individual systems and at the population level that hot Jupiters experience tidal inspiral before the end of their host stars’ main-sequence lifetimes. Ultra-short-period (USP) planets have orbital periods P < 1 day, rocky compositions, and are expected to experience tidal decay on similar timescales to hot Jupiters if the efficiency of tidal dissipation inside their host stars parameterized as

is independent of P and/or secondary mass M
p. Any difference between the two classes of systems would reveal that a model with constant

is insufficient. If USP planets experience tidal inspiral, then USP planet systems will be relatively young compared to similar stars without USP planets. Because it is a proxy for relative age, we calculate the Galactic velocity dispersions of USP planet candidate host and non-host stars using data from Gaia Data Release 2 supplemented with ground-based radial velocities. We find that main-sequence USP planet candidate host stars have kinematics consistent with similar stars in the Kepler field without observed USP planets. This indicates that USP planet hosts have similar ages to field stars and that USP planets do not experience tidal inspiral during the main-sequence lifetimes of their host stars. The survival of USP planets requires that

Secular Resonances in Nonrestricted Hierarchical Triple Systems
Authors: Tan Pan , Hou Xiyun , Liao Xinhao , Wang Wenlei , Tang Jingshi 
Published: August 2020

Abstract
In this paper, the averaged Hamiltonian of a nonrestricted hierarchical triple system truncated at the third order is investigated. First, each secular resonant term is studied. For the well-studied secular quadrupole theory, it is analytically reformulated in a different manner in our work. The resonance width is numerically determined and displayed on the

plane (also denoted as the

plane). In terms of the octupole terms, we show that for a near-planar configuration of the system, considerable variations of both the eccentricities of the inner and outer orbits can be generated by a single resonant term. The resonance width for every secular resonant angle from the octupole terms is also numerically determined and displayed on the

plane. The results show that an orbit flip with a near-perpendicular initial mutual inclination is possible for each secular resonance. By displaying the resonance widths of different resonant terms on the same

plane, we intuitively show the overlap of different secular resonances. Then, the full averaged Hamiltonian with both quadrupole and octupole terms is investigated using the Poincaré surface of section, with a special focus on the orbit flip. For the cases we exploited, we find that the near-planar flip of the inner orbit can be either regular or chaotic while the outer orbit flip is generally chaotic.
Gas-driven Inspiral of Binaries in Thin Accretion Disks
Authors: Tiede Christopher , Zrake Jonathan , MacFadyen Andrew , Haiman Zoltan 
Published: August 2020

Abstract
Numerical studies of gas accretion onto supermassive black hole binaries have generally been limited to conditions where the circumbinary disk (CBD) is 10–100 times thicker than expected for disks in active galactic nuclei. This discrepancy arises from technical limitations, and also from publication bias toward replicating fiducial numerical models. Here we present the first systematic study of how the binary’s orbital evolution varies with disk scale height. We report three key results: (1) binary orbital evolution switches from outspiraling for warm disks (aspect ratio h/r ∼ 0.1), to inspiraling for more realistic cooler, thinner disks at a critical value of h/r ∼ 0.04, corresponding to orbital Mach number

. (2) The net torque on the binary arises from a competition between positive torque from gas orbiting close to the black holes, and negative torque from the inner edge of the CBD, which is denser for thinner disks. This leads to increasingly negative net torques on the binary for increasingly thin disks. (3) The accretion rate is modestly suppressed with increasing Mach number. We discuss how our results may influence modeling of the nano-Hz gravitational-wave background, as well as estimates of the Laser Interferometer Space Antenna merger event rate.
Gamma-Ray Urgent Archiver for Novel Opportunities (GUANO): Swift/BAT Event Data Dumps on Demand to Enable Sensitive Subthreshold GRB Searches

Published: August 2020

Abstract
We introduce a new capability of the Neil Gehrels Swift Observatory to provide event-level data from the Burst Alert Telescope (BAT) on demand in response to transients detected by other instruments. We show that the availability of these data can effectively increase the rate of detections and arcminute localizations of gamma-ray bursts (GRB) like GRB 170817 by >400%. We describe an autonomous spacecraft-commanding pipeline purpose built to enable this science; to our knowledge, this is the first fully autonomous extremely low-latency commanding of a space telescope for scientific purposes. This pipeline has been successfully run in its complete form since 2020 January, and has resulted in the recovery of BAT event data for >800 externally triggered events to date (gravitational waves, GWs; neutrinos; GRBs triggered by other facilities; fast radio bursts; and very high-energy detections), now running with a success rate of ∼90%. We exemplify the utility of this new capability by using the resultant data to (1) set the most sensitive upper limits on prompt 1 s duration short GRB-like emission within ±15 s around the unmodeled GW burst candidate S200114f, and (2) provide an arcminute localization for short GRB 200325A and other bursts. We also show that using data from GUANO to localize GRBs discovered by other instruments, we can increase the net rate of arcminute-localized GRBs by 10%–20% per year. Along with the scientific yield of more sensitive searches for subthreshold GRBs, the new capabilities designed for this project will serve as the foundation for further automation and rapid target of opportunity capabilities for the Swift mission, and have implications for the design of future rapid-response space telescopes.
On the Formation of Lyman β and the O i 1027 and 1028 Å Spectral Lines
Authors: Hasegawa Takahiro , Noda C. Quintero , Shimizu Toshifumi , Carlsson Mats 
Published: August 2020

Abstract
We study the potential of Lyman β and the O i 1027 and 1028 Å spectral lines to help in understanding the properties of the chromosphere and transition region (TR). The oxygen transitions are located in the wing of Lyman β, which is a candidate spectral line for the solar missions Solar Orbiter/Spectral Imaging of the Coronal Environment and Solar-C (EUVST). We examine the general spectroscopic properties of the three transitions in the quiet Sun by synthesizing them assuming nonlocal thermal equilibrium and taking into account partial redistribution effects. We estimate the heights where the spectral lines are sensitive to the physical parameters, computing the response functions to temperature and velocity using a 1D semiempirical atmospheric model. We also synthesize the intensity spectrum using the 3D enhanced network simulation computed with the Bifrost code. The results indicate that Lyman β is sensitive to the temperature from the middle chromosphere to the TR, while it is mainly sensitive to the line-of-sight (LOS) velocity at the lower atmospheric layers, around 2000 km above the optical surface. The O i lines form lower in the middle chromosphere, being sensitive to the LOS velocities at heights lower than those covered by Lyman β. The spatial distribution of the intensity signals computed with the Bifrost atmosphere, as well as the inferred velocities from the line core Doppler shift, confirms the previous results. Therefore, these results indicate that the spectral window at 1025 Å contains several spectral lines that complement each other to seamlessly trace the thermal structure and gas dynamics from the middle chromosphere to the lower TR.

Abstract
We present the final Sloan Digital Sky Survey IV (SDSS-IV) quasar catalog from Data Release 16 of the extended Baryon Oscillation Spectroscopic Survey (eBOSS). This catalog comprises the largest selection of spectroscopically confirmed quasars to date. The full catalog includes two subcatalogs (the current versions are DR16Q_v4 and DR16Q_Superset_v3 at https://data.sdss.org/sas/dr16/eboss/qso/DR16Q/): a “superset” of all SDSS-IV/eBOSS objects targeted as quasars containing 1,440,615 observations and a quasar-only catalog containing 750,414 quasars, including 225,082 new quasars appearing in an SDSS data release for the first time, as well as known quasars from SDSS-I/II/III. We present automated identification and redshift information for these quasars alongside data from visual inspections for 320,161 spectra. The quasar-only catalog is estimated to be 99.8% complete with 0.3%–1.3% contamination. Automated and visual inspection redshifts are supplemented by redshifts derived via principal component analysis and emission lines. We include emission-line redshifts for Hα, Hβ, Mg ii, C iii], C iv, and Lyα. Identification and key characteristics generated by automated algorithms are presented for 99,856 broad absorption-line quasars and 35,686 damped Lyman alpha quasars. In addition to SDSS photometric data, we also present multiwavelength data for quasars from the Galaxy Evolution Explorer, UKIDSS, the Wide-field Infrared Survey Explorer, FIRST, ROSAT/2RXS, XMM-Newton, and Gaia. Calibrated digital optical spectra for these quasars can be obtained from the SDSS Science Archive Server.
L’émergence de la pulsion de vie dans le corpus freudien : de la biologie helmholtzienne à la métapsychologie
Authors: Tran The Jessica 
Published: August 2020

À travers une archéologie de l’émergence des questionnements relatifs aux principes de régulation du fonctionnement psychique dans le corpus freudien, nous tenterons d’éclairer la manière dont la notion métapsychologique de « pulsion de vie » a pu émerger dans l’œuvre de Freud. Nous pourrons observer que, dès leurs débuts, les considérations théoriques freudiennes ont présenté une autonomie manifeste au regard d’un point de vue strictement biologique. Après nous être intéressés aux fondements physiques du modèle épistémologique de Freud, et notamment à l’influence de l’École de Helmholtz et du principe thermodynamique d’entropie, nous pourrons nous pencher sur les remaniements introduits par la définition de la pulsion de vie en 1920, pour préciser comment, loin de réhabiliter une théorie du vivant dans la pensée freudienne, elle vient au contraire redoubler l’émancipation et l’autonomie du concept métapsychologique de pulsion au regard de toute considération biologique.
Pulsion de vie : lier coûte que coûte, investir sans fin, espérer toujours, aimer encore…
Authors: Lavallée Guy 
Published: August 2020

La pulsion de vie est une élaboration de l’excitation de vie. Comme telle, elle s’exprime à la fois par une constante activité de liaison hallucinatoire et positive, un affect d’Espoir, des capacités d’investissement significatives, et surtout un mouvement psychique amoureux qui se déploie jusqu’aux extrêmes. La défense maniaque accompagne l’Éros dans sa lutte contre le risque entropique d’effondrement du moi. La destructivité provient surtout des défenses du moi fourvoyant l’Éros en utilisant notamment l’emprise (hétérodestructrice) et l’envie (auto et hétérodestructrice). Avec nos patients, adultes et adolescents, dans l’analyse de la négativité, comment nous situer « du côté de la vie » ? Si nous y parvenons, la question du bonheur comme affect de vie peut se poser.
À propos du texte de Rosine Jozef Perelberg : « Amour et mélancolie dans les analyses de femmes par des femmes »
Authors: Chabert Catherine 
Published: August 2020

Le texte de Rosine Perelberg à propos des cures de femmes avec des femmes ouvre des voies associatives plurielles, à la fois cliniques et métapsychologiques. D’une part, le transfert « homosexuel » et l’excitation qu’il génère peuvent être combattus par une idéalisation exacerbant le narcissisme ; d’autre part, l’actualisation des angoisses de séparation et de perte se heurte au noyau mélancolique. Les deux sont susceptibles de se conjuguer dans un même mouvement que l’auteur rattache à une érotique mélancolique prise dans le double courant des pulsions de vie et des pulsions de mort. Enfin, le retournement mélancolique de la haine contre le moi et la libération des fantasmes homosexuels tentent de masquer la rivalité mortifère avec l’analyste.

Published: August 2020

Abstract
The role of IL-21, produced mainly by Th17 cells and T follicular helper cells, has been intensively investigated in B cell differentiation and Ab class switch. However, how IL-21 regulates memory IgA+ B cell development and memory IgA responses in the intestines is still not completely understood. In this study, we found the total IgA+ B cells as well as CD38+CD138−IgA+ memory B cells were significantly increased in intestinal lamina propria (LP) of TCRβxδ−/− mice after transfer of microbiota Ag-specific Th17 cells but not Th1 cells. Although IL-21R−/− mice or IL-17R−/− mice showed decreased Ag-specific memory IgA production in the intestines upon infection with Citrobacter rodentium, the percentage of IgA+CD38+CD138- memory B cells in Peyer’s patches and LP was decreased only in IL-21R−/− mice, but not in IL-17R−/− mice, after reinfection with C. rodentium compared with wild-type mice. Blockade IL-21 in vivo suppressed intestinal C. rodentium–specific IgA production as well as IgA+CD38+CD138− memory B cells in Peyer’s patches and LP. Furthermore, IL-21 significantly induced B cell IgA production in vitro, with the increased expression of genes related with class-switching and memory B cell development, including Aicda, Ski, Bmi1, and Klf2. Consistently, Aicda and Ski expression was decreased in B cells of IL-21R−/− mice after C. rodentium reinfection. In conclusion, our study demonstrated that IL-21 promotes intestinal memory IgA B cell development, possibly through upregulating differentiation-related and class switching–related genes, indicating a potential role of IL-21 in memory IgA+ B cell responses in the intestines.
Zebrafish F-box Protein fbxo3 Negatively Regulates Antiviral Response through Promoting K27-Linked Polyubiquitination of the Transcription Factors irf3 and irf7

Published: August 2020

Abstract
FBXO3, belongs to the F-box family of proteins, which has been reported to involve in host autoimmune and inflammatory responses by promoting its substrates for ubiquitylation. However, thus far, its physiological function in antiviral immunity remains elusive. In this study, we report that overexpression of zebrafish fbxo3 suppresses cellular antiviral responses. Moreover, disruption of fbxo3 in zebrafish increases the survival rate upon spring viremia of carp virus exposure. Further assays indicate that fbxo3 interacts with irf3/irf7 and specifically catalyzes K27-linked ubiquitination of irf3 and irf7, resulting in proteasomal degradation of irf3 and irf7. However, the F-box domain of fbxo3 is not required for fbxo3 to interact with irf3/irf7 and to inhibit transactivity of irf3 and irf7. This study provides novel insights into fbxo3 function and the underlying mechanisms. In addition, it sheds new light on the regulation of IFN-I signaling by F-box proteins.

A promising way to increase the use of buckwheat is the wider introduction of technologies for its processing, including grinding of non-hulled grain. It requires the search for new plant materials with more suitable characteristics. In this work, the possibilities to use the grain of a new artificial buckwheat species Fagopyrum hybridum for flour production are studied in comparison with two cultivated species F. tataricum and F. esculentum. Some chemical characteristics of F. hybridum flour were evaluated. According to the size of the kernel fragments in different modes of milling within each species the significant differences were identified within F. esculentum and F. hybridum (p <0.001 and p <0.05, respectively); there were no significant differences within F. tataricum (p >0.1). Fragments of the seed hulls of F. tataricum and F. hybridum compared to ones of F. esculentum were distinguished by the absence of pronounced acute angles. For the cultivated species, amino acid compositions of grain protein of the studied samples manifest no strong deviations from earlier published results. The new species F. hybridum has the amino acid composition similar to ones of the both cultivated species with slight superiority in the content of all essential amino acids. So, the content of Cysteine, Tryptophan, Arginine, Lysine, Methionine, Leucine + Isoleucine, Threonine, Histidine and Valine in seeds of F. hybridum was 5.2, 15.0, 25.8, 30.2, 31.2, 36.0, 38.4, 41.1 and 46.2% higher compared to F. tataricum and 11.1, 43.7, 39.2, 3.7, 31.2, 15.2, 14.8, 20.0, 18.9% higher compared to F. esculentum. Using DPPH it was assessed the antioxidant activity (AOA) of whole grain flour of three buckwheat species and decreasing of the AOA during heating up to 100 °C. After water extraction the AOA was maximal for F. tataricum flour; F. hybridum and F. esculentum manifested similar values with the same decline dynamics during heating. After ethanol extraction the flour of F. hybridum shown higher AOA compared to both cultivated species before temperature treatment (1.3 times) as well as after heating to 100 °C (1.2 times). The results of the analysis of the fractional composition of flour from the whole grain of the three buckwheats shown the fragments of the seed hulls of F. tataricum and F. hybridum compared to ones of F. esculentum were characterized by the absence of pronounced acute angles. Additional experiments are needed to optimize the technology of whole-grain buckwheat flour. But the grain of F. tataricum and F. hybridum looks like more suitable for these purposes than the non-hulled grain of F. esculentum.

In the last century, there have been significant progress in the fields of health-care system and academics. The experience of implementing community-oriented medical education for more than last 5 decades at the Mahatma Gandhi Institute of Medical Sciences (MGIMS), Sewagram, based on Gandhian ideology has helped us to develop a mutually beneficial partnership with local health system and community and to discharge our social responsibility. The institute has made several innovations in its academics and health care to raise the social consciousness of medical students as well as equip them to work in rural areas. We are sharing the innovations along with our experience of working in partnership with public health system and community for their further replication elsewhere.
