Abstract
We present two bright galaxy candidates at z ∼ 12–13 identified in our H-dropout Lyman break selection with 2.3 deg2 near-infrared deep imaging data. These galaxy candidates, selected after careful screening of foreground interlopers, have spectral energy distributions showing a sharp discontinuity around 1.7 μm, a flat continuum at 2–5 μm, and nondetections at <1.2 μm in the available photometric data sets, all of which are consistent with a z > 12 galaxy. An ALMA program targeting one of the candidates shows a tentative 4σ [O iii] 88 μm line at z = 13.27, in agreement with its photometric redshift estimate. The number density of the z ∼ 12–13 candidates is comparable to that of bright z ∼ 10 galaxies and is consistent with a recently proposed double-power-law luminosity function rather than the Schechter function, indicating little evolution in the abundance of bright galaxies from z ∼ 4 to 13. Comparisons with theoretical models show that the models cannot reproduce the bright end of rest-frame ultraviolet luminosity functions at z ∼ 10–13. Combined with recent studies reporting similarly bright galaxies at z ∼ 9–11 and mature stellar populations at z ∼ 6–9, our results indicate the existence of a number of star-forming galaxies at z > 10, which will be detected with upcoming space missions such as the James Webb Space Telescope, Nancy Grace Roman Space Telescope, and GREX-PLUS.
Multiwavelength Analysis and the C iv

Abstract
The flat-spectrum radio quasar B2 1633+382 (4C 38.41) has been monitored for several years and has presented correlated variability in multiple wavelengths. In this article, we are performing different analyses for multiple frequencies, from gamma rays to radio, as well as the C iv
λ1549 Å emission line and the λ1350 Å continuum. Using the nonthermal dominance parameter, we separated the C iv and the continuum light curves for when the dominant source of continuum is the accretion disk or the jet. We found a correlation at a delay consistent with zero between the line and the continuum dominated by disk emission indicating a very small broad-line region (BLR). From the resulting delay between the 15 GHz and gamma rays, we estimated the distance of the gamma-ray emission region from the jet apex to be ∼37 pc. The C iv flux decreases when the continuum and gamma rays increase at some of the high-activity periods. The C iv profile presents a larger variable component in its blue wing. The relation between the luminosities of C iv and the continuum does not completely follow the relation for a quasar sample. Our results lead us to propose an outflow of BLR material in the jet flow direction, a gamma-ray production through magnetic reconnection for the flaring event of mid-2011, and that there is not enough BLR material close to the radio core to be easily ionized by the nonthermal continuum.
Please Repeat: Strong Lensing of Gravitational Waves as a Probe of Compact Binary and Galaxy Populations
Authors: Xu Fei , Ezquiaga Jose María , Holz Daniel E. 
Published: April 2022

Abstract
Strong gravitational lensing of gravitational wave sources offers a novel probe of both the lens galaxy and the binary source population. In particular, the strong lensing event rate and the time-delay distribution of multiply imaged gravitational-wave binary coalescence events can be used to constrain the mass distribution of the lenses as well as the intrinsic properties of the source population. We calculate the strong lensing event rate for a range of second- (2G) and third-generation (3G) detectors, including Advanced LIGO/Virgo, A+, Einstein Telescope (ET), and Cosmic Explorer (CE). For 3G detectors, we find that ∼0.1% of observed events are expected to be strongly lensed. We predict detections of ∼1 lensing pair per year with A+, and ∼50 pairs per year with ET/CE. These rates are highly sensitive to the characteristic galaxy velocity dispersion, σ
*, implying that observations of the rates will be a sensitive probe of lens properties. We explore using the time-delay distribution between multiply imaged gravitational-wave sources to constrain properties of the lenses. We find that 3G detectors would constrain σ
* to ∼21% after 5 yr. Finally, we show that the presence or absence of strong lensing within the detected population provides useful insights into the source redshift and mass distribution out to redshifts beyond the peak of the star formation rate, which can be used to constrain formation channels and their relation to the star formation rate and delay-time distributions for these systems.
Quasar UV Luminosity Function at 3.5 < z < 5.0 from SDSS Deep Imaging Data
Authors: Pan Zhiwei , Jiang Linhua , Fan Xiaohui , Wu Jin , Yang Jinyi 
Published: April 2022

Abstract
We present a well-designed sample of more than 1000 type 1 quasars at 3.5 < z < 5 and derive UV quasar luminosity functions (QLFs) in this redshift range. These quasars were selected using the Sloan Digital Sky Survey (SDSS) imaging data in the Stripe 82 and overlap regions with repeat imaging observations that are about 1 mag fainter than the SDSS single-epoch data. The follow-up spectroscopic observations were conducted by the SDSS-III Baryon Oscillation Spectroscopic Survey (BOSS) as one of the BOSS ancillary programs. Reaching i ∼ 21.5 mag, our sample bridges previous samples from brighter and deeper surveys. We use a 1/V
a method to derive binned QLFs at 3.6 < z < 4.0, 4.0 < z < 4.5, and 4.5 < z < 4.9 and then use a double power-law model to parameterize the QLFs. We also combine our data with literature QLFs to better constrain the QLFs across a much wider luminosity baseline. The faint- and bright-end slopes of the QLFs in this redshift range are around −1.7 and −3.7, respectively, with uncertainties from 0.2 to 0.3 to >0.5. The evolution of the QLFs from z ∼ 5 to 3.5 can be described by a pure density evolution model (∝10
kz
) with a parameter k similar to that at 5 < z < 7, suggesting a nearly uniform evolution of the quasar density at z = 3.5–7.

Introduction: There is limited data on clinical course and outcomes of hospitalized adults with COVID-19 in Nepal. Thus, it is imperative to characterize the features of this disease in the domestic context.
Methodology: We identified all adult patients with laboratory-confirmed COVID-19 admitted to five different hospitals in Nepal from June 15 to July 15, 2020. We collected epidemiological, socio-cultural and clinicopathologic data, and stratified the patients based on their symptom status.
Results: The study included 220 patients with an overall median age of 31.5 (25-37) years, and 181 (82.3%) were males. 159 (72.3%) were asymptomatic, and 163 (74.1%) were imported cases. Of 217 patients with the available data, 110 (50.7%) reported their annual household income less than 2000 US dollars, and 122 (56.2%) practiced Pranayama (yogic rhythmic breathing techniques) regularly. Eight patients (3.6%) required supplemental oxygen and two patients (0.9%) died. None of the patients who practiced Pranayama regularly required supplemental oxygen. Compared to asymptomatic patients, symptomatic patients had greater proportion of females (31.1% vs. 12.6%, p = 0.001), imported cases (85.2% vs. 69.8%, p = 0.02), illiterates (26.8% vs. 12.1%, p = 0.01), alcohol users (43.3% vs. 24.5%, p = 0.01), and had higher platelet count (253×109/L vs. 185×109/L, p = 0.02).
Conclusions: Most cases were imported, asymptomatic young males, with very few deaths. Pranayama practice was associated with protection against severe COVID-19, but more data is needed to substantiate this. The association of platelets count with symptom status in the Nepalese population needs further exploration.
Identification of the first case of Penicillium marneffei infection in Shaanxi province by nanopore sequencing
Authors: Liu Dongli , Ma Lin , Mao Lingfeng , Wang Yiqun , Ding Long , Wang Anli 
Published: April 2022

Introduction: Penicillium marneffei is one of the most common opportunistic infectious fungi associated with AIDS (Acquired Immunodeficiency Syndrome). It is prevalent in Southeast Asia and southern China (such as Guangdong), but rare in inland provinces of China. Penicillium marneffei infections are often misdiagnosed.
Case Report: Here, we report a patient with Penicillium marneffei infection from Shaanxi Province, China, who was previously repeatedly diagnosed as Kala-azar in two hospitals. The patient received medical treatment due to fever and multiple papules, worked as a tour guide, and had travel history in Southeast Asian countries. We performed nanopore genome sequencing on blood samples of the patient and obtained 84,000 reads in 3.5 hours. The average length of the sequences was 7088.7 bases and the longest sequence was 87471 bases. Through comparison with the pathogenic bacteria database, 13 homologous Penicillium marneffei sequences were identified. Furthermore, by using specific quantitative real time-polymerase chain reaction of Penicillium marneffei, fungal ITS (Internal Transcribed Spacer) sequencing, and fungal biphasic culture, we further confirmed the pathogen as Penicillium marneffei. Meanwhile, the patient was confirmed to be HIV (Human Immunodeficiency Virus) positive. Thus, the patient was diagnosed with AIDS combined with Penicillium marneffei infection, which, to the best of our knowledge, is the first report of Penicillium marneffei infection in Shaanxi Province, China.
Conclusions: Metagenomic analysis based on nanopore sequencing provides an important reference for the diagnosis of Penicillium marneffei infection in this case.

Published: April 2022

Introduction: Besides stomach, the oral cavity is the second reservoir of Helicobacter pylori (H. pylori) that plays an important role in oral diseases and recurrent gastric infection. This study aimed to determine the risk factors of oral H. pylori infection for better human health.
Methodology: Saliva samples from 280 subjects who visited the dental clinics were collected for the H. pylori antigen test. The data regarding age, gender, residence, frequency of tooth brushing, presence of dental caries and/or periodontitis were reported for each participant. Stool antigen Helicobacter pylori test was used to detect gastric infection.
Results: The overall prevalence of H. pylori in oral cavity and stool were 40.4%; 95% CI [34.8–46.2], and 36.4%; 95% CI [31–42.2], respectively and were not statistically significant (p = 0.546). The differences of positive rates of H. pylori infection according to the presence of periodontitis (54.7% vs 30.1%, p < 0.001, OR; 95% CI: 2.8 (1.7-4.6)) and dental caries (47.1% vs 32%, p = 0.001, OR; 95% CI: 2.2 (1.3-3.5)) were statistically significant. Living in rural areas increases the risk of acquiring H. pylori infection compared with urban areas (46.9% vs 34.7%, p < 0.001, OR; 95% CI: 0.6 (0.4-1)).
Conclusions: The H. pylori antigen test on saliva could be used as evidence of gastric infection. Oral diseases including periodontal diseases and caries are important risk factors for H. pylori colonization, so the professional treatment of these diseases may reduce the rate of new and recurrent gastric infection by H. pylori.
De l’école de la dépendance aux chaînes globales de valeur. L’héritage sous-estimé de la théorie économique de Rosa Luxemburg
Authors: Bürbaumer Benjamin 
Published: April 2022

À contre-courant de l’idée répandue selon laquelle ses travaux auraient simplement mené dans une impasse théorique, cet article propose de montrer l’influence considérable (mais sous-estimée) de Rosa Luxemburg sur la pensée économique. L’étude contemporaine des chaînes globales de valeur a été impulsée par Luxemburg. Dans un premier temps, cet article s’appuie sur l’analyse de l’intégration de la périphérie dans le capitalisme exposée dans L’Accumulation du capital . Luxemburg se singularise par une analyse pionnière du « développement du sous-développement ». Dans un deuxième temps, nous montrons que des auteurs désireux de comprendre le sous-développement persistant des pays du sud global, même après la décolonisation, ont puisé dans les écrits de Luxemburg. Enfin, l’article montre que l’imbrication polarisante entre pays du centre et pays de la périphérie, mise en lumière par Luxemburg, représente le point de départ conceptuel de l’analyse contemporaine des flux de marchandises internationaux, qui se déroulent à la fois en deçà et au-delà de l’échelle de l’État-nation.
1895 : le cinéma, « une histoire-monde »
Authors: Albera François , Chabin André 
Published: April 2022

À la faveur d’un entretien, François Albera retrace la genèse de la revue 1895 Revue d’Histoire du Cinéma dont il est rédacteur en chef : il en détaille les évolutions depuis le numéro 0 en 1985, porté par l’Association française pour l’histoire du cinéma. Il souligne son difficile chemin vers la reconnaissance universitaire et éditoriale tout en l’inscrivant plus largement dans les mues de l’écriture de l’histoire du cinéma au niveau mondial. Il met en lumière la variété des recherches sur les différentes facettes du médium cinéma dont de nombreux aspects – filmiques et non-filmiques – restent à étudier, études dont les bornes temporelles ne cessent d’être repoussées. Interrogé sur la cinéphilie aujourd’hui, Albera constate ses déplacements vers une pratique de « niches » patrimoniales, nostalgiques, teintées d’érudition et constate combien place de la critique de cinéma s’est érodée dans les journaux et les revues généralistes en même temps que les revues de cinéma périclitent.
Incluir y representar en espacios militantes: identidad colectiva y feminización del activismo en la Plataforma de Afectadas por la Hipoteca
Authors: Emperador Badimon Montserrat 
Published: April 2022

Un desafío para los colectivos por el derecho a la vivienda es lograr una amplia movilización. Para la Plataforma de Afectadas por la Hipoteca (PAH), este objetivo de inclusión pasa por la promoción de una identidad colectiva basada en la transversalidad de la inseguridad habitacional y por la feminización del activismo. Este artículo explora las implicaciones de este doble trabajo, identitario y de feminización, así como su resultado ambivalente en materia de inclusión y de representación. Si bien es cierto que en la PAH predominan las mujeres y hay una elevada participación de activistas de origen migrante, la representación de la experiencia especifica de las mujeres racializadas y/o extranjeras queda diluida en el tipo de identidad colectiva promovida. A partir de una investigación cualitativa, se articula el enfoque cultural de los movimientos sociales, la sociología del trabajo feminista y el enfoque interseccional.
Le populisme comme phénomène de communication : une comparaison transversale et longitudinale des campagnes politiques sur Facebook
Authors: Klinger Ulrike , Koc-Michalska Karolina 
Published: April 2022

Dans cet article, nous envisageons la notion de populisme comme un phénomène de communication qui comprend des éléments typiques de contenu (le peuple, l’anti-élitisme et l’exclusion des hors-groupes) et de style (l’évocation de la peur, la simplification excessive et le registre de langue), nous éloignant ainsi des approches centrées sur les acteurs pour adopter une approche centrée sur les contenus. Empiriquement, notre étude mesure les différents degrés et les différentes formes de populisme à travers l’analyse de 3564 posts Facebook publiés sur les pages de partis politiques en France, en Allemagne et au Royaume-Uni pendant les campagnes des élections européennes de 2014, les campagnes des élections parlementaires nationales de 2017 et une période non électorale dans chaque pays en 2018. Les résultats montrent que le populisme n’est pas un phénomène marginal, mais qu’il est présent dans environ un quart des messages ; qu’il existe des distinctions dans le temps entre les pays, les types de partis, les domaines politiques. Si les partis radicaux sont très exclusifs à l’égard des groupes marginaux à droite et très anti-élitistes à gauche et à droite, cette observation ne donne qu’une vision partielle du phénomène multiforme du populisme.

Abstract
Malignant ascites is a common clinical problem in ovarian cancer. NK cells are present in the ascites, but their antitumor activity is inhibited. The underlying mechanisms of the inhibition have yet to be fully elucidated. Using an Fcγ receptor–mediated NK cell activation assay, we show that ascites from ovarian cancer patients potently inhibits NK cell activation. Part of the inhibitory activity is mediated by CA125, a mucin 16 fragment shed from ovarian cancer tumors. Moreover, transcriptional analyses by RNA sequencing reveal upregulation of genes involved in multiple metabolic pathways but downregulation of genes involved in cytotoxicity and signaling pathways in NK cells purified from ovarian cancer patient ascites. Transcription of genes involved in cytotoxicity pathways are also downregulated in NK cells from healthy donors after in vitro treatment with ascites or with a CA125-enriched protein fraction. These results show that ascites and CA125 inhibit antitumor activity of NK cells at transcriptional levels by suppressing expression of genes involved in NK cell activation and cytotoxicity. Our findings shed light on the molecular mechanisms by which ascites inhibits the activity of NK cells and suggest possible approaches to reactivate NK cells for ovarian cancer immunotherapy.
Ayush Kwath to combat COVID-19
Authors: Sharma Charu , Sharma Meenakshi , Mandal Sisir K. , Nanoti Leena 
Published: April 2022

Background:
Public health crises threatening the world have emerged as Covid pandemic. The present analysis is aimed to analyze and summarize the therapeutic potential of the herbal formulae—Ayush Kwath as a preventive, curative, and restorative intervention. The treatment for COVID-19 should primarily aim for the resolution of symptoms, arresting the pathogenesis at the earliest and shortening the recovery phase. With these objectives, the clinical efficiency of Ayush Kwath is being traversed in this study.

Materials and Methods:
A thorough search of classical text and databases was done using key terms Ayurveda, Jwara, Tulsi, Sunthi, Dalchini, and Krishna Marich.

Results:
The study found that Ayush Kwath can serve as an empirical drug for the disease. Our findings are categorized under (1) clinical perspectives of Ayush Kwath, (2) pharmacology and reverse-pharmacology of the formulation—its role in therapeutics of COVID-19, (3) psychoneuroimmunological mechanism of the formulation w.r.t. each of the constituents’ drugs, (4) therapeutic potential of the formulation—levels of prevention.

Conclusion:
From this review, efficacy of traditional medicines in Covid pandemic might be evidenced. This can back the clinical evidence of Ayurveda management of COVID-19. The drug can be labeled under “Vyadhiviprita chikitsaupakrama” and its application is a function of a Vaidya's rationality. Considering lower economical value, therapeutic efficacy, and good availability of the drug makes it a potent entity to deal with a public health concern such as coronavirus disease.
Importance of Ghrita (clarified butter) as an antitoxic medicine in Visha Chikitsa (treatment of poison)
Authors: Yadav Seema , Kadu Amol , Patel Narsingh 
Published: April 2022

Background:

Ghrita (clarified butter), which is being used as a medicine or as an adjuvant in various Agad formulations for the treatment of different poisoning conditions such as animate and inanimate poisons and for establishing its action with a contemporary view.

Settings and Design:
The review method adopted was a critical review in which classical and contemporary literature was extensively researched and critically evaluated. The conceptual contribution of Ayurveda science in the field of toxicology has been symbolized.

Methods and Materials:
The classical texts, mainly Charaka, Sushruta, Ashtanga Samgraha, and Ashtang Hridaya, were researched along with their commentaries in Sanskrit as well as Hindi. All collected matter of various research articles were searched and scrutinized for discussion, and an effort is made to exert some productive conclusions.

Results and Conclusions:

Ghrita used with various formulations plays an important role in Visha Chikitsa because of its Vishaghna (antipoisonous), use in skin disease, cardioprotective, and blood-purifying properties. It is used as an antidote having an antipoisonous property either as medicine or as an adjuvant by various routes such as oral, local application and Nasya, Anjana (corrylium). Ghrita is not only used in all kinds of poison, but it is also used in all states of poisoning. Different therapeutic measures such as Santrasan (mild purgation), Pralepa (external application of paste on skin), Bhojya (food), and Aushdh (drugs) should not be utilized without adding Ghrita for the management of different poisoning conditions.

Authors: Pandey Narayan , Sharma Anita , Kadu Vd. A. , Gautam Shankar 
Published: April 2022

Background:
Snakebite is a major problem worldwide, and a common medical emergency. There are many treatment modalities available for snake bites, among them Chaturvimsati Vishachikitsopakrama are Ayurveda treatment modality mentioned in Charaka Samhita. The concept and procedures of few Upakramashas also been clearly defined in other Samhitas like Sushruta, Astangasamgraha, Astangahrdaya.

Aims and Objectives:
To understand the role of Chaturvimsati Vishachikitsopakramain the management of snake bite with the help of Bruhatravi, Laghutrayi and contemporary science

Materials and Methods:
The keywords such as snake, snake bite, Chaturvimsati Vishachikitsopakrama, management of snakebite were searched from literary of classical text books like CharakaSamhita, SushrutaSamhita, Astanga Hridaya, etc with its responsive commentators, various databases (PubMed, Google scholar, Research gate, Ayush Dhara).

Results:
There are few traditional healers who are practicing some of the treatment modality of Vishochikitsopakram such as Mantra, Arista, Aaushad etc. Same procedure has been advocated in contemporary science with different terminology. In other hand few treatment modalities mentioned to avoid in snake bite management such as Utkartan, Chushan etc.

Conclusion:
Among the classical 24 treatment modalities, few are scientifically validated whereas few need to be studied and some are found irrelevant in the current scenario. Many Upakramas are scientifically approachable, easily accessible, cost effective, time saving and can be performed anywhere. So, these treatment modalities should be researched and implemented with the advancement of this era.
