Abstract
The Vega planetary system hosts the archetype of extrasolar Kuiper belts and is rich in dust from the sub-astronomical unit region out to hundreds of astronomical units, suggesting intense dynamical activity. We present Atacama Large Millimeter/submillimeter Array (ALMA) millimeter observations that detect and resolve the outer dust belt from the star for the first time. The interferometric visibilities show that the belt can be fit by a Gaussian model or by power-law models with a steep inner edge (at 60–80 au). The belt is very broad, extending out to at least 150–200 au. We strongly detect the star and set a stringent upper limit to warm dust emission previously detected in the infrared. We discuss three scenarios that could explain the architecture of Vega’s planetary system, including the new ALMA constraints: no outer planets, a chain of low-mass planets, and a single giant planet. The planetless scenario is only feasible if the outer belt was born with the observed sharp inner edge. If, instead, the inner edge is currently being truncated by a planet, then the planet must be

and at

to have cleared its chaotic zone within the system age. In the planet chain scenario, outward planet migration and inward scattering of planetesimals could produce the hot and warm dust observed in the inner regions of the system. In the single giant planet scenario, an asteroid belt could be responsible for the warm dust, and mean motion resonances with the planet could put asteroids on star-grazing orbits, producing the hot dust.

Abstract
We present a multiwavelength investigation of the radio galaxy population in the galaxy cluster MOO J1506+5137 at z = 1.09 ± 0.03, which in previous work we identified as having multiple complex radio sources. The combined data set used in this work includes data from the Low-Frequency Array Two-meter Sky Survey, NSF’s Karl G. Jansky Very Large Array, the Robert C. Byrd Green Bank Telescope, the Spitzer Space Telescope, and the Dark Energy Camera Legacy Survey. We find that there are five radio sources, which are all located within 500 kpc (∼1′) of the cluster center and have radio luminosities P
1.4 GHz > 1.6 × 1024 W Hz−1. The typical host galaxies are among the highest stellar mass galaxies in the cluster. The exceptional radio activity among the massive galaxy population appears to be linked to the dynamical state of the cluster. The galaxy distribution suggests an ongoing merger, with a subgroup found to the northwest of the main cluster. Furthermore, two of the five sources are classified as bent-tail sources, with one being a potential wide-angle tail/hybrid morphology radio source, indicating a dynamic environment. The cluster also lies in a region of the mass–richness plane occupied by other merging clusters in the Massive and Distant Clusters of WISE Survey. The data suggest that during the merger phase, radio activity can be dramatically enhanced, which would contribute to the observed trend of increased radio activity in clusters with increasing redshift.

Abstract
While protoplanetary disks often appear to be compact and well organized in millimeter continuum emission, CO spectral line observations are increasingly revealing complex behavior at large distances from the host star. We present deep Atacama Large Millimeter/submillimeter Array maps of the J = 2−1 transition of 12CO, 13CO, and C18O, as well as the J = 3−2 transition of DCO+, toward the T Tauri star RU Lup at a resolution of ∼0.3″ (∼50 au). The CO isotopologue emission traces four major components of the RU Lup system: a compact Keplerian disk with a radius of ∼120 au, a non-Keplerian “envelope-like” structure surrounding the disk and extending to ∼260 au from the star, at least five blueshifted spiral arms stretching up to 1000 au, and clumps outside the spiral arms located up to 1500 au in projection from RU Lup. We comment on potential explanations for RU Lup’s peculiar gas morphology, including gravitational instability, accretion of material onto the disk, or perturbation by another star. RU Lup’s extended non-Keplerian CO emission, elevated stellar accretion rate, and unusual photometric variability suggest that it could be a scaled-down Class II analog of the outbursting FU Ori systems.

Abstract
Using the PMO-13.7 m millimeter telescope at Delingha in China, we have conducted a large-scale simultaneous survey of 12CO, 13CO, and C18O J = 1 − 0 emission toward the sky region centered at l = 209.°7, b = −2.°25 with a coverage of 4.°0 × 4.°5. The majority of the emission in the region comes from the clouds with velocities lying in the range from −3 to 55 km s−1, at kinematic distances from 0.5 to 7.0 kpc. The molecular clouds in the region are concentrated into three velocity ranges. The molecular clouds associated with the 10 H ii regions/candidates are identified and their physical properties are presented. Massive stars are found within Sh2-280, Sh2-282, Sh2-283, and BFS54, and we suggest them to be the candidate excitation sources of the H ii regions. The distributions of the excitation temperature and line width with the projected distance from the center of H ii region/candidate suggest that the majority of the 10 H ii regions/candidates and their associated molecular gas are three-dimensional structures, rather than two-dimensional structures.

Abstract
Without the protection of a global magnetic field, erosion of the Martian ionosphere by the solar wind leads to abundant loss of atmospheric particles. Although the crustal magnetic fields in the Martian southern hemisphere are strong enough to affect the dayside-induced magnetosphere, there is still limited evidence for the deflection of the solar winds by the crustal magnetic fields. With 4 years of ion data measured by the Mars Atmosphere and Volatile EvolutioN mission, we investigate the flow pattern of protons, O+, and

when the crustal fields rotate to different local times. Our result is the first evidence that suggests the crustal magnetic fields can withstand the solar wind flows on the Martian dayside and can effectively trap heavy ions below 1000 km. The gyroradii of heavy ions in the strong crustal fields regions are one order of magnitude smaller than in other regions. The trapping effect causes different flow patterns, while the crustal fields rotate to different subsolar regions but are attenuated at higher altitudes. Observations provide essential information to investigate the effect of the crustal magnetic fields on heavy-ion flows and understand the role of the crustal magnetic fields in the interaction between the solar wind and the Martian atmosphere.

Abstract
Maturation of lymphoid cells is controlled by the action of stage and lineage-restricted transcription factors working in concert with the general transcription and chromatin remodeling machinery to regulate gene expression. To better understand this functional interplay, we used Biotin Identification in human embryonic kidney cells to identify proximity interaction partners for GATA3, TCF7 (TCF1), SPI1, HLF, IKZF1, PAX5, ID1, and ID2. The proximity interaction partners shared among the lineage-restricted transcription factors included ARID1a, a BRG1-associated factor complex component. CUT&RUN analysis revealed that ARID1a shared binding with TCF7 and GATA3 at a substantial number of putative regulatory elements in mouse T cell progenitors. In support of an important function for ARID1a in lymphocyte development, deletion of Arid1a in early lymphoid progenitors in mice resulted in a pronounced developmental arrest in early T cell development with a reduction of CD4+CD8+ cells and a 20-fold reduction in thymic cellularity. Exploring gene expression patterns in DN3 cells from Wt and Arid1a-deficient mice suggested that the developmental block resided in the DN3a to DN3b transition, indicating a deficiency in β-selection. Our work highlights the critical importance of functional interactions between stage and lineage-restricted factors and the basic transcription machinery during lymphocyte differentiation.

Abstract
Deglycosylated, live-attenuated SIV vaccines elicited protective immune responses against heterologous SIVsmE543-3, which differs from the vaccine strain SIVmac239 to levels similar to those across HIV-1 clades. Two thirds of the vaccinees contained the chronic SIVsmE543-3 infection (controllers), whereas one third did not (noncontrollers). In this study, we investigated immune correlates of heterologous challenge control in rhesus macaques of Burmese origin. Because depletion of CD8+ cells in the controllers by administration of anti-CD8α Ab abrogated the control of viral replication, CD8+ cells were required for the protective immune response. However, classical SIV-specific CD8+ T cells did not account for the protective immune response in all controllers. Instead, IL-15–responding CD8α+ cells, including CD8+ T and NK cells, were significantly higher in the controllers than those in the noncontrollers, before and after vaccination with deglycosylated SIV. It is well established that IL-15 signal transduction occurs through “trans-presentation” in which IL-15 complexed with IL-15Rα on monocytes, macrophages, and dendritic cells binds to IL-15 Rβ/γ expressed on CD8+ T and NK cells. Accordingly, levels of IL-15 stimulation were strongly affected by the depletion of monocytes from PBMCs, implying key roles of innate immune cells. These results suggest that intrinsic IL-15 responsiveness may dictate the outcome of protective responses and may lead to optimized formulations of future broadly protective HIV vaccines.

CAREGIVING END-OF-LIFE EXPERIENCES AND WELLBEING OF CAREGIVERS OF CARDIAC PATIENTS: MEDIATING ROLE OF CAREGIVING SELF EFFICACY
Authors: Sultan Sarwat , Kanwal Frasat , Kanwal Sumreen 
Published: August 2020

Objectives: To investigate the role of caregiving self-efficacy as mediator between the relationship of experiences of caregivers of dying heart patients with caregivers’ wellbeing. Methodology: Participants of this study were 211 caregivers of heart patients at Institute of Cardiology Multan. Caregivers aged 26-57 years provided data on three scales measuring End-of-Life experiences, caregiving wellbeing and caregiving self-efficacy. Results: Mediating effect of caregiving self-efficacy was supported through the path analysis on AMOS-21 between end-of-life care experiences and wellbeing of caregivers. Findings indicated that caregivers confronted high negative experiences and low well-being among caregivers of cardiac patients. Results also showed that caregivers' negative end-of-life care experiences such as physical suffering and burden significantly negatively affect their level of wellbeing; and positive and neutral experiences have positive impression on wellbeing. However, caregiving self-efficacy reported by caregivers mediate the effects of these experiences on their wellbeing. Conclusion: Assumed paths in model between the study variables supported the claim that caregivers’ self-efficacy intervened as mediator between caregiving experiences while giving during terminal period of dying patients and caregiver’s own wellbeing. Findings suggested that if caregiving self-efficacy is high among caregivers, they may undergo negative experience less and may have high wellbeing during end-of-life care.

OBJECTIVE: To study the proportion of positive exercise stress test in younger patients coming to tertiary care hospital for the evaluation of ischaemic heart disease (IHD). Our secondary objective was to find out the difference of risk profile between the relatively younger and elderly population having IHD. METHODOLOGY: This descriptive cross sectional study was conducted at cardiology department of a tertiary care centre at Karachi, Pakistan during July 1st 2018 to December 31st 2018 (six months). All adult patients whose exercise tests had been turned positive were selected for the study. Patients with history of arrhythmias, conduction defects, valvular heart diseases, co-morbid conditions like cirrhosis, stroke, osteoarthritis, chronic kidney disease were excluded from the study. The risk factors of interest were hypertension, diabetes Mellitus, smoking, lipid disorders and obesity. RESULTS: Total 85 patients were selected for the study. Out of them, 73 (85.9%) were male and 12 (14.1%) were female. Mean age of our patients was 56.2±8.7 years. Out of 85 patients, 33 (38.8 %) were falling into the category of younger (< 55 years) patients, while elderly (≥ 55years) patients were 52 (61.2%). In comparison to younger population, diabetes mellitus (34.6 vs 15.2 %; P-value = 0.04) and smoking (23.1 vs 6.1%; P-value= 0.03%) were significantly more prevalent in elderly individuals. Prevalence of Hypertension was slightly higher in younger population (78.8 vs 73.1 %; P-value 0.5) as compare to elderly population. Similarly, younger population were found to be more obese (36.4 vs 28.8 %; P-value 0.4) as compared to elderly population. Prevalence of lipid disorder was almost equal between both the groups (40.4 vs 39.4%; P-value=0.9). CONCLUSION: The burden of Ischaemic heart disease is growing in our younger population and every third of our ischaemic patient is among the younger age group. Although proportion of diabetes and smoking is less common in younger population, trend of hypertension and obesity is on rise.

Estimating solar radiation according to semi empirical approach of Perrin de Brichambaut: application on several areas with different climate in Algeria

Published: August 2020

The solar energy reaching a given surface is directly dependent on the orientation thereof and the position of the sun. To get maximum energy from the sun, it is necessary a good solar receiver orientation towards the solar radiation where the solar radiation is perpendicular to the solar collector, so the knowledge of the sun's position over time is a very important thing. The intensity calculate of solar radiation received by an inclined surface is the primary objective of this paper. The study is based on the true solar time, the geographic and astronomical data on-site study. Matlab was the simulation tool, where a program was developed to calculate the daily global solar radiation collected by any geographical site depending on the semi-empirical model of PERRIN DE BRICHAMBAUT. The some applications on different places in Algeria, like El-Oued, Biskra, Blida and Oran in the day of March 21, June 21, September 21 and December 21, and the results obtained were confirmed by comparing them with the previously results published by the researchers is of great competence in this field.
