Abstract
The feedback from the accretion of central supermassive black holes (SMBHs) is a hot topic in the coevolution of SMBHs and their host galaxies. By tracing the large-scale outflow using the line profile and bulk velocity shift of [O iii]λ5007, the evolutionary role of outflow is studied here on a large sample of 221 type 2 quasars (QSO2s) extracted from Reyes et al. By following our previous study on local Seyfert 2 galaxies, the current spectral analysis on the Sloan Digital Sky Survey spectroscopic database enables us to arrive at the following results: (1) by using the Lick indices, we confirm that QSO2s are, on average, more frequently associated with younger stellar populations than Seyfert galaxies; (2) QSO2s with a stronger outflow tend to be associated with a younger stellar population, which implies a coevolution between the feedback from SMBHs and the host in QSO2s; (3) although occupied at the high L

Published: June 2023

Abstract
Sending astronauts to Mars will be a milestone of future deep space exploration activities. However, energetic particle radiation in deep space and in the Mars environment is a major risk to the health of future human explorers. The nominal Martian surface radiation field contains primary Galactic Cosmic Ray (GCR) particles and secondary particles generated in the Martian atmosphere and the regolith. Some of these secondary particles may propagate upward and even be detected at the orbit of Mars contributing to the orbit radiation. Studying the Mars orbit radiation environment is critical for planning future Mars orbital missions. Therefore, we calculate the Martian orbit radiation dose rate considering the primary GCR spectra provided by the Badhwar-O’Neill 2014 model and the secondary particles modeled by the state-of-the-art Atmospheric Radiation Interaction Simulator. Specifically, we calculate the integral dose rate of each particle type and its dependence on orbit height, surface pressure, and solar modulation intensity. Our analysis shows that modulation intensity is the most dominating factor and that different surface pressures make less than a 1% impact. We also derive the sensitive energy range of detected particles contributing to the dose rate and further validate our prediction against the measured data by Liulin-MO on TGO at a circular orbit around Mars. This may conduce to predicting the radiation risks in Mars orbit and providing constructive reference parameters for the crewed space industry.

events in the era of third-generation observatories like Cosmic Explorer and the Einstein Telescope. Each event is analyzed using Bayesian inference to determine properties of the source including component masses, spins, tidal parameters, and the distance to the source. These inference products are the fodder for some of the most exciting gravitational-wave science, enabling us to measure the expansion of the universe with standard sirens, to characterize the neutron-star equation of state, and to unveil how and where gravitational-wave sources are assembled. In order to maximize the science from the coming deluge of detections, we introduce GWCloud, a searchable repository for the creation and curation of gravitational-wave inference products. It is designed with five pillars in mind: uniformity of results, reproducibility of results, stability of results, access to the astronomical community, and efficient use of computing resources. We describe how to use GWCloud with examples, which readers can replicate using the companion code to this paper. We describe our long-term vision for GWCloud.
Catalog of Planetary Nebulae Detected by GALEX and Corollary Optical Surveys
Authors: Gómez-Muñoz M. A. , Bianchi L. , Manchado A. 
Published: June 2023

Abstract
Planetary nebulae (PNs) consist of an ionized envelope surrounding a hot central star (CSPN) that emits mostly at ultraviolet (UV) wavelengths. UV observations, therefore, provide important information on both the CSPN and the nebula. We have matched the PNs in the Hong Kong/Australian Astronomical Observatory/Strasbourg Hα catalog with the Galaxy Evolution Explorer (GALEX) UV sky surveys, the Sloan Digital Sky Survey (SDSS) data release 16, and the Panoramic Survey Telescope and Rapid Response System (Pan-STARRS) PS1 second release. A total of 671 PNs were observed by GALEX with the far-UV (FUV; 1344 Å–1786 Å) and/or the near-UV (NUV; 1771 Å–2831 Å) detectors on (GUVPNcat); 83 were observed by SDSS (PNcatxSDSSDR16) and 1819 by Pan-STARRS (PNcatxPS1MDS). We merged a distilled version of these matched catalogs into GUVPNcatxSDSSDR16xPS1MDS, which contains a total of 375 PNs with both UV and optical photometry over a total spectral coverage of ∼1540 Å–9610 Å. We analyzed separately 170 PNs resolved in GALEX images and determined their UV radius by applying a flux profile analysis. The CSPN flux could be extracted separately from the PN emission for 8 and 50 objects with SDSS and Pan-STARRS counterparts, respectively. The multiband photometry was used to distinguish between compact and extended PNs and CSPNs (binary CSPNs) by color–color diagram analysis. We found that compact PN candidates could be identified by using the r − i < − 0.4 and −1 < FUV−NUV < 1 colors, whereas binary CSPN candidates in given T
eff ranges (all with color r−i > −0.4) can be identified in the color region (FUV−NUV) ≤ 6(r−i)+1.3, −0.8 < FUV−NUV < 0.4, and r−i < 0.75.
Communauté européenne de défense et Communauté politique européenne : Les propositions d’Alcide De Gasperi
Authors: Preda Daniela 
Published: June 2023

Au début des années 1950, Alcide De Gasperi s’est engagé de manière décisive pour l’unification politique de l’Europe. La paix est au centre de ses préoccupations et il voit dans la fédération européenne un « mythe de paix ». En partageant les idées des fédéralistes européens, il est allé bien au-delà d’une adhésion générique au projet de Communauté de défense (CED) proposé par les Français. Il s’est battu avec ténacité pour lier l’armée européenne à la création d’une Communauté politique, et donc à la naissance d’une « patrie européenne », et pour transformer l’approche fonctionnaliste en approche fédéraliste.
Les représentations de l’unité chez Jean Monnet
Authors: Bossuat Gérard 
Published: June 2023

Quels furent les projets d’unité de Jean Monnet ? Les recherches sur Monnet ont d’abord investi le champ du plan Schuman, oubliant que Monnet avait formulé des projets d’unité européenne atlantique et mondiale dès la période de la Société des Nations. Dès 1919, il voulait organiser le monde pour la paix grâce à la SDN. En 1943, le thème de l’unité européenne est lié à la politique étrangère du général de Gaulle qui, à la différence de Monnet, adopte une politique de force contre l’Allemagne. Il faut attendre le 9 mai 1950 pour voir cette politique cesser officiellement. L’obsession européenne n’est plus centrale dans les projets encore vagues d’Union des hommes ou d’Union universelle. Jean Monnet a toujours recherché la paix, mais a réussi l’Union européenne.
Entre littérature et philosophie d’autrefois : quelques correspondances remarquables
Authors: Stanguennec André 
Published: June 2023

Des œuvres littéraires et philosophiques majeures des xix e et xx e siècles sont mises en correspondance, jusque dans les années 1960, où sont abandonnées les anciennes références au moi exalté des romans introspectifs, au sens du monde historique des grandes épopées idéologiques, et à l’idéal absolu de l’art, de la religion, de la métaphysique. Cet abandon conduisit à des cas extrêmes d’indifférenciation entre littérature et sciences humaines. Toutefois, l’engouement parallèle pour une autobiographie existentielle non réductionniste ou pour l’enquête policière allégorisant en première personne la réflexion métaphysique, de même que le déferlement des romans de science-fiction cosmiques et théologiques, semblent témoigner du déplacement déguisé d’un désir refoulé, celui de trois absolus, le moi, le monde, Dieu, plutôt que de son irréversible disparition.
Comparison of shoulder external rotation fatigue protocols on kinetic determinants and fatigue index in overhead athletes: a cross over study
Authors: Ali R. , Ali I. , Sharma S. 
Published: June 2023

Abstract
The purpose of present study is to compare prone lying and half kneeling external rotator fatigue protocols on the kinetic parameters of external rotators and fatigue index in collegiate overhead athletes. Twenty overhead collegiate male athletes were recruited in this randomised cross-over experimental study design with two different shoulder external rotator fatigue protocols. Subjects were performed with prone lying and half kneeling shoulder external rotation fatigue protocol with a washout period of at least 72 h. Outcome measures like peak force, peak velocity, peak power, average power, and total work were observed in concentric and eccentric contraction and fatigue index was assessed before and after fatigue protocols. Concentric peak force (P=0.001), peak velocity (P<0.001), peak power (P<0.001), average power (P<0.001) and total work (P=0.022) showed significant time difference whereas group difference and time× group interaction was found to be non-significant. Similarly, eccentric peak force (P=0.043), average power (P=0.001) and total work (P=0.032) showed only significant time difference. Prone-lying and half kneeling external rotation fatigue protocols reduces the peak force, peak velocity, peak power and total work in concentric contraction and peak force and total work in eccentric contraction in a similar fashion.

With the continuous expansion of educational view, blockchain technology develops into the cutting-edge applied science and technology of educational information construction. Blockchain technology can effectively solve such problems as information security and trust crisis in the current application of big data in online education by virtue of its characteristics of decentralization, traceability, multi-party consensus mechanism, and high trust. Blockchain technology is conducive to protecting online educational resources, strengthening the transparency of online teaching resources, simplifying the copyright transaction process, and thus enhancing the scientific and technological innovation ability of teachers. Studies regarding the blockchain technology application in education were analyzed, and the influences of the four aspects of the blockchain technology application in education on online teaching resource sharing were explored. Results showed that the Cronbach α coefficient of the questionnaire designed in this research was 0.856, and the KMO value was 0.859, indicating its good reliability and validity. The cross-institutional learning record storage space, learning certificate management mechanism, and collaboratively developed educational ecosystem of the blockchain technology application in education obviously promoted online teaching resource sharing at a significance level of 5%. The results are important reference values for strengthening the integration of educational resources under blockchain technology, improving the application mechanism of online digital educational resources, and improving the accurate service quality of online educational resources.
Tackling Adverse COVID-19 Situation in India: A Perspective on Frontline Health-Care Workers
Authors: Bisai Ankan , Sengupta Debjani 
Published: June 2023

Background:
As of December 17, 2021, India has been reporting a daily increase of over 7447 in fresh COVID-19 cases, total over 3.4 crore cases. Lack of knowledge and perceptions among health-care workers (HCWs) can pose challenges to disease control. HCWs are high-risk group for COVID-19; Adequate knowledge and COVID appropriate behavior can help prevent and contain the disease. Only early diagnosis and quarantine with proper management help to limit the COVID-19 transmission.

Methodology:
A cross-sectional study was carried for 30 days, from the September 16, 2020–October 15, 2020, in a block of Paschim Medinipur, West Bengal, with varying cumulative incidence of COVID-19 cases. A 36-item survey instrument on various domains was adapted for assessment of COVID-19 awareness.

Results:
The survey was conducted among 115 frontline HCWs engaged in screening and treating COVID-19 patients. Survey results indicated that majority have good knowledge about the disease, its symptom, testing, management guidelines but lack of knowledge found on mode of organ damage and home isolation advices. Addressing their perceptions and placing additional focus on practices across all health facilities is recommended as a preparedness measure.

Conclusions:
As the global threat of COVID-19 still continues to emerge, targeted interventions are required for HCWs, and further studies are warranted on field level HCWs.
Comparative Analysis of Electro-Chemiluminescence Immunoassay, Enzyme-Linked Immunosorbent Assay and Rapid Immunochromatographic Test for Detection of Hepatitis B Surface Antigen
Authors: Shahid Mohammad , Sami Hiba , Khan Parvez Anwar , Sharma Sanjay , Singh Amritesh Kumar , Husaini Syed Haider M. , Khan Haris Manzoor 
Published: June 2023

Background:
Electro-chemiluminescence immunoassay (ECLIA), enzyme-linked immunosorbent assay (ELISA), and rapid immunochromatographic test (RICT) are currently commonly used for the detection of hepatitis B surface antigen (HBsAg). Although a few studies have been performed to compare the efficiency of these three different serological assays, but there are still many grey areas where clear guidelines are required to give the reports as reactive or nonreactive.

Materials and Methods:
We compared three different methods of detecting HBsAg: RICT, ELISA and ECLIA. The aim of this cross-sectional study was to analyze the performance of these tests and evaluate the cut off index (COI) of ECLIA to be considered as positive. Some of the representative samples that showed a discrepancy between ELISA and ECLIA were confirmed by nucleic acid amplification test (NAAT).

Results:
A total of 3846 samples were included in the study, of which 259 (6.73%) were positive by ECLIA. Of these 259 samples, 68 were positive by both ECLIA and ELISA and had COI of >5 in ECLIA, whereas 191 were positive by ECLIA only (COI between 0.9 and 5). Hence, the concordance rates of the ECLIA and ELISA in detecting serum HBsAg was 26.25% while the same for ELISA and RICT was 31.57%. Four representative samples which were positive by ECLIA and ELISA (i.e., COI >5) were positive with NAAT. However, one sample which was negative by ELISA and positive by ECLIA (i.e., COI <5) was negative by NAAT. Cohen’s K showed moderate agreement between ELISA and RICT and fair agreement between ELISA and ECLIA.

Conclusions:
ECLIA seems a promising and sensitive test to detect HBsAg, however, we suggest, samples with COI between 1 and 5 should be reported cautiously and preferably be combined with NAAT or any other molecular method before considering as positive.
flujo de caja como determinante de la estructura financiera de las empresas españolas. Un análisis en tiempos de crisis
Authors: Rodríguez-Masero Natividad , López-Manjón Jesús D. 
Published: June 2023

Este trabajo propone el uso de la variable Flujo de Caja Contable de la Explotación (FCE) como un factor con incidencia significativa en la estructura financiera de la empresa española en un periodo (2008-2012) caracterizado por dificultades para la financiacion empresarial. En la literatura previa son escasos los trabajos que tienen en cuenta esta variable, midiendo la liquidez en la mayoría de los casos con datos obtenidos del Balance y la Cuenta de Resultados y no del Estado de Flujos de Efectivo (EFE). Metodológicamente se usa un análisis multivariante con datos de panel aplicados a una muestra de grandes empresas españolas no cotizadas. Adicionalmente, este trabajo se inserta en el debate teórico existente en la literatura acerca de los factores determinantes de la estructura financiera de las empresas. Los resultados indican que un modelo basado en datos del EFE, principalmente el FCE tiene capacidad predictiva de dicha estructura financiera.
