Long-term Periodicities in Kepler Photometry of Open Cluster NGC 6811

Published: September 2020

Abstract
Long-term photometric variability can sometimes be related to the emergence of starspots in the photosphere following a quasi-periodic magnetic activity cycle. In order to investigate the existence and properties of magnetic cycles in a narrow range of fundamental parameters, we focused on solar-type stars in the intermediate-age open cluster NGC 6811 (1 Gyr). The cluster membership was analyzed both in terms of stellar kinematics and Gaia photometry. Rotation periods and photometric variability were analyzed for 138 stars from Kepler light curves and we discuss the existing trends and relationships. We also searched a sample of 11 solar-type stars for cycle-like periodicities and in each case classified the variability as either cyclic, multicyclic, flat, or acyclic. The results suggest a significant scatter, possibly due to sensitive nonlinearities in the dynamo process. This raises theoretical questions on whether these periodicities can be associated to activity cycles and what determines the stellar cycle presence or its period. Also, the lack of solar-twin flat activity stars in NGC 6811 combined with other recent results, suggests that the presence of magnetic grand minima in the Sun is a relatively recent phenomenon.

Abstract
Observations with the Australia Telescope Compact Array revealed intrahour variations in the radio source PKS B1322-110. As part of an optical follow-up, we obtained Gemini Hα and Hα continuum (HαC) images of the PKS B1322-110 field. A robust 19σ detection of PKS B1322-110 in the Hα−HαC image prompted us to obtain the first optical spectrum of PKS B1322-110. With the Gemini spectrum we determine that PKS B1322-110 is a flat-spectrum radio quasar at a redshift of z = 3.007 ± 0.002. The apparent flux detected in the Hα filter is likely to originate from He ii emission redshifted precisely on the Galactic Hα narrowband filter. We set upper limits on the emission measure of the Galactic plasma, for various possible cloud geometries.
Painted Gallo-Roman Figurines in Vendeuil-Caply
Authors: Bossard Adrien 
Published: September 2020

In 2013, an archaelogical team exploring the site of Vendeuil-Caply in northern France brought to light a new corpus of Gallo-Roman terracotta figurines. The particular importance of this corpus lies in the preservation of pigments that decorated the surface of these figurines. From the 19th century onwards, the generic term that has been used to refer to this kind of Gallo-Roman production has been “white-clay,” most often associated with the Allier region of central France. This term arose from the stark, white color of the fabric. Consequently, archaeologists were quite surprised to find not only color on the figurines, but also repetitive patterns, such as feathers, or details of clothing.
Contribution/soutien des espaces à l'autodirection : un exemple d'hybridation du virtuel et du physique à l'université de Lorraine
Authors: Chateau Anne , Bailly Sophie , Willié Valérie 
Published: September 2020

Contrairement à certaines plateformes de e-learning commerciales qui tendent à vider les espaces physiques dans les institutions de formation en langues, la plateforme en cours de création à l'université de Lorraine a été pensée, dès sa genèse, pour soutenir l'apprentissage auto-dirigé des langues en Centre de ressources en langues (CRL) (Maquart-Willié, 2012) et en faire la promotion. Elle est appelée à devenir un des piliers d'un environnement global qui comprend également les différents CRL de l'université, l'objectif étant de faciliter l'autonomisation des apprentissages de langues. Plutôt que de mettre en concurrence les espaces physiques et virtuels, cet environnement vise leur hybridation ou symbiose. Notre hypothèse est que l'interdépendance des deux permettra à chacun de combler les manques de l'autre : l'environnement hybride ainsi obtenu offrira la possibilité de concilier la présence et la distance, l'indépendance et l'accompagnement, la flexibilité et les contraintes. La plateforme – avec son espace de travail global pour les acteurs impliqués dans l'apprentissage des langues (apprenants, personnels des CRL, enseignants) – vise à la fois à stimuler l'utilisation des lieux physiques et à intensifier leur activité (en facilitant la promotion d'évènements ou l'inscription aux services proposés) ainsi qu'à rassembler des acteurs distants. Nous étudions ici la dynamique générée par cet environnement à partir de traces quantitatives et qualitatives d'activités menées dans les CRL et sur la plateforme. L'hybridation entre espaces physiques et virtuels semble déboucher sur l'essaimage de pratiques innovantes.
Survivances carnavalesques au Maroc
Authors: Hachim Mouna 
Published: September 2020

Chaque année, se déroulent au Maroc des festivités qui sont l’occasion d’observer des réminiscences vivaces, sous une forme plus ou moins édulcorée, de rites carnavalesques, caractérisés par des spectacles burlesques et des processions masquées. C’est le cas de la cérémonie de Boujoud (l’Homme aux peaux), survenant juste après la grande fête du Sacrifice. C’est le cas également de Achoura, représentation de l’année qui meurt et ses symbolismes liés à l’organisation du monde et à la permanence cyclique de la vie et de la mort. Que dire de Yennayer dont les symbolismes universels de « portes de l’année » étaient l’occasion dans tout le Maghreb de grandes festivités dont le point commun étaient des rites de purification, de renouvellement et de placement de la nouvelle année sous les meilleurs augures ? Sans oublier le surprenant Sultan des étudiants qui voyait l’intronisation par les étudiants des medersas d’un roi-bouffon. Autant d’expressions originales du vécu, du légué, du pensé, du ressenti, du créé… qui étonnent par leur permanence malgré la captation par le monothéisme et la méfiance des pouvoirs.

Abstract
HIV type 1 is associated with pulmonary dysfunction that is exacerbated by cigarette smoke. Alveolar macrophages (AM) are the most prominent immune cell in the alveolar space. These cells play an important role in clearing inhaled pathogens and regulating the inflammatory environment; however, how HIV infection impacts AM phenotype and function is not well understood, in part because of their autofluorescence and the absence of well-defined surface markers. The main aim of this study was to evaluate the impact of HIV infection on human AM and to compare the effect of smoking on their phenotype and function. Time-of-flight mass cytometry and RNA sequencing were used to characterize macrophages from human bronchoalveolar lavage of HIV-infected and -uninfected smokers and nonsmokers. We found that the frequency of CD163+ anti-inflammatory AM was decreased, whereas CD163−CCR7+ proinflammatory AM were increased in HIV infection. HIV-mediated proinflammatory polarization was associated with increased levels of inflammatory cytokines and macrophage activation. Conversely, smoking heightened the inflammatory response evident by change in the expression of CXCR4 and TLR4. Altogether, these findings suggest that HIV infection, along with cigarette smoke, favors a proinflammatory macrophage phenotype associated with enhanced expression of inflammatory molecules. Further, this study highlights time-of-flight mass cytometry as a reliable method for immunophenotyping the highly autofluorescent cells present in the bronchoalveolar lavage of cigarette smokers.
AKT Regulates NLRP3 Inflammasome Activation by Phosphorylating NLRP3 Serine 5

Published: September 2020

Abstract
The cytosolic pattern recognition receptor NLRP3 senses host-derived danger signals and certain microbe-derived products in both humans and rodents. NLRP3 activation assembles an inflammasome complex that contains the adapter proteins ASC and caspase-1, whose activation triggers the maturation and release of the proinflammatory cytokines IL-1β and IL-18. S5 phosphorylation of NLRP3 prevents its oligomerization and activation, whereas dephosphorylation of this residue by the phosphatase PP2A allows NLRP3 activation. However, the protein kinase that mediates NLRP3 S5 phosphorylation is unknown. In this study, we show that AKT associates with NLRP3 and phosphorylates it on S5, limiting NLRP3 oligomerization. This phosphorylation event also stabilizes NLRP3 by reducing its ubiquitination on lysine 496, which inhibits its proteasome-mediated degradation by the E3 ligase Trim31. Pharmacologic manipulation of AKT kinase activity reciprocally modulates NLRP3 inflammasome-mediated IL-1β production. Inhibition of AKT reduced IL-1β production following the i.p. injection of LPS into mice. We propose that AKT, Trim31, and PP2A together modulate NLRP3 protein levels and the tendency to oligomerize, thereby setting a tightly regulated threshold for NLRP3 activation.

Brucellosis has continued to become a disease of major economic concern in developing countries. In a study to determine the seroprevalence of brucellosis in small ruminants in Zaria, Kaduna State, Nigeria, 1036 samples comprising 768 goats from institutional farms (n=384) and a slaughter slab (n=384), and 268 sheep all from institutional farms were used. The sera samples obtained from the animals were subjected to the Modified Rose Bengal Plate Test (m-RBPT) followed by Serum Agglutination Test with ethylene diamine tetraacetic acid (SAT-EDTA) for Brucella antibodies detection. Milk samples were collected from lactating sheep and goats and subjected to the Milk Ring Test (MRT) for detection of Brucella antibodies. Results of the study revealed an overall seroprevalence rate of 6.37%, 8.90% and 12.96% for m-RBPT, SAT-EDTA and MRT, respectively. The seroprevalence in sheep and goats showed significant species difference (P < 0.05) for m-RBPT (10.05% vs 5.08%), but insignificant (P > 0.05) species difference for SAT-EDTA (9.33% vs 8.72%) and MRT (15.00% vs 11.76%) respectively. The seroprevalence in males and females showed insignificant sex difference (P > 0.05) for m-RBPT (6.59% vs 6.21%) and SAT-EDTA (7.76% vs 9.66%). On the other hand, the seroprevalence was higher in young (< 1 year old) than adult (> 1 year old) animals for SAT-EDTA (15.32% vs 8.11%). The seroprevalence in Red Sokoto, Sahel and West African Dwarf goats showed significant breed difference (P < 0.05) for m-RBPT (4.59% vs 5.55% vs 8.33%) and SAT-EDTA (6.80% vs 16.67% vs 12.50%). It was concluded that the seroprevalence of brucellosis was higher in sheep, Sahel goats and younger animals. To understand the pattern and dynamics of transmission of brucellosis in different groups of animals, there is the need for further studies to identify the Brucella species circulating in small ruminants.

Published: September 2020

Artificial Intelligence which seemed to be a distant dream at some point has now come out of the science fiction movies to our reality and has gathered momentum over past few years and has led to many developments in almost all the sectors. No sector will remain untouched by artificial intelligence and Intellectual Property Rights too will not be an exception to the same. The impact of Artificial Intelligence in the field of Intellectual Property Rights will be two ways, on one hand Artificial Intelligence will prove to be an asset in the areas of patent and patent search tools, accurate and timely research, providing a mechanism to sort out inventions and ideas and provide with a mechanism to the innovator on the patents already existing similar to his idea and many other things but on the other hand the Artificial Intelligence might also prove to be a threat to innovation and creativity which is the heart and soul of Intellectual Property Rights. The research paper will discuss in detail about the impact of Artificial Intelligence on Intellectual Property Rights, the pros and cons of Artificial Intelligence on creativity and innovation in IPR and will also deal with the future scope of Artificial Intelligence in Intellectual Property Rights.

Palestine Radar Model (PRM) for Predicting the Number of Infected Cases of COVID-19 Virus in Palestine
Authors: Abu Omar Dr. Mohammad 
Published: September 2020

In the light of the COVID-19 virus pandemic that has attacked the earth planet, all nations in the world are becoming suffered more and more from the increasing number of infected cases. The medical infrastructure in most countries aren’t fit to deal with such pandemic, hospitals in these countries are unable to accommodate a such number of the infected cases that have recently been recorded[1],[5]. This pandemic has put countries in a great predicament; they never expected to face a pandemic of this size [1], [5]. Palestine is one of these pandemic victims, COVID-19 virus has started spreading in Palestine on fifth March of 2020 [4]. Palestinian government and leadership have announced immediately by its Prime Minister Dr Mohammad Shtayyeh the case of emergency in Palestine to prevent this dangerous pandemic from spreading, by closing all schools and universities, crowding prevention, limiting motion and asking people strongly for home-stay [1], [2], [4]. With this step, Palestine has been recorded as one of the most quick-response countries of facing the COVID-19 pandemic in the world [4]. Although the emergency case is still very active in Palestine, the Palestine government and people are still very worry and afraid from the coming future, this is for two main reasons, the first is the inability of Palestine medical infrastructure to process the large numbers of infected cases, the second is the social-cultural system in Palestine that has strong relationships and traditions that promotes social communication in Palestine which may help the COVID-19 virus for more spreading. So, this study aims to help Palestinian government to be ready as possible to face this pandemic in the coming days, by designing a computerized model to predict the expected numbers of the infected cases that may be recorded in the coming days.
