ARCHITECTURAL MEMORY AND FORMS OF ITS EXISTENCE
Authors: Remizova Olena
Published: September 2020

The article attempts to highlight the traces of memory in the theory, history and practice of architecture. The subject of research is the existing forms of memory in architecture. It is traditionally accepted that the “history of architecture” as a science is the main repository of knowledge about the evolution of architecture. Facts and artifacts, descriptions of monuments and cities are retained in it. The article emphasizes that the traditional “history of architectural objects” is not the only form of memory. Another equally important and complicated aspect of the architectural memory is detected during the decoding of the evolution of project activity and its language. Analysis of the evolution of architecture allowed us to differentiate the epochs in which historical thinking prevails: the Renaissance, Romanticism, Eclecticism, Art Deco, Postmodernism. They are characterized by such ways of thinking as dialogical, historical and typological, historical and associative. They are opposed to design approaches in which abstract thinking dominates (Art Nouveau and Modernism). The article shows that the concept of architectural memory has many shades and manifests itself in a variety of different forms of professional consciousness. As historical knowledge, memory exists in such forms as: a chronological description, science of history, evolutionary studies, catalog of styles, museum, archive. In designing and its language, memory is represented in such forms as canon, dialogue with bygone era, norm, architectural fantasy, remembrance, historical association, reconstruction, restoration and others. It is shown that the most important way of storing and transferring information is the architectural language and compositional logic. Postmodern consciousness raised the problem of loss of memory and the development of architectural language and communication of culture.
Long-term Periodicities in Kepler Photometry of Open Cluster NGC 6811
Authors: Velloso E. N. , Nascimento, Jr. J.-D. do , Saar S. H.
Published: September 2020

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.

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.
Who writes Harry Potter fan fiction? Passionate detachment, "zooming out," and fan fiction paratexts on AO3
Authors: Duggan Jennifer
Published: September 2020

Who reads and writes fan fiction—and why—has long been a central concern of fan studies. Indeed, many of the foundational works in the field of fan studies aim to answer this question. These early studies set a paradigm for our understanding of who makes up fan fiction–centered communities nearly thirty years ago; however, it is clear that the paradigm is now outdated. To my knowledge, there are no wide-scale academic studies of how fan fiction authors identify themselves in online profiles, authors' notes, and other self-descriptive texts, although some fans have produced statistics. Rather, our understandings of fan fiction–centered communities instead rest on our own embedded experiences as fans. While our experiences are valuable, recent work has made it clear that focusing solely on our embedded perspectives may exclude a number of voices, experiences, and viewpoints from scholarly work. This article presents the results of a qualitative study that examines how fan fiction authors described themselves in the paratexts of 1,939 Harry Potter fan fiction works posted to Archive of Our Own (AO3)—over 1 percent of the Harry Potter fan fiction posted to AO3 at the time of the study. It aims to indicate demographic trends within the Harry Potter fandom, identify groups of fans who may have been elided from fan studies' core discourse, discuss why who writes fan fiction matters, and uncover future areas of research concern.
Revisiting parasocial theory in fan studies: Pathological or (path)illogical?
Authors: Groszman Rivkah
Published: September 2020

Parasocial theory is not currently in favor within fan studies because it is seen as depicting fan behavior as pathological. However, an examination of the original text and its modern interpretations reveals the true, neutral image of fans that parasocial theory portrays, which allows it to be applied to fan communities and fan works. Accordingly, these applications are also discussed, with an emphasis on the K-pop industry, where the theory is particularly relevant.

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.
COVID-19 Contact Tracing
Authors: Scassa Teresa
Published: September 2020

This article surveys the rise of contact tracing technologies during the COVID-19 pandemic and some of the privacy, ethical, and human rights issues they raise. It examines the relationship of these technologies to local public health initiatives, and how the privacy debate over these apps made the technology in some cases less responsive to public health agency needs. The article suggests that as countries enter the return to normal phase, the more important and more invasive contact tracing and disease surveillance technologies will be deployed at the local level in the context of employment, transit, retail services, and other activities. The smart city may be co-opted for COVID-19 surveillance, and individuals will experience tracking and monitoring as they go to work, shop, dine, and commute. The author questions whether the attention given to national contact tracing apps has overshadowed more local contexts where privacy, ethical, and human rights issues remain deeply important but relatively unexamined. This raises issues for city local governance and urban e-planning.

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
Authors: Zhao Wei , Shi Chong-Shan , Harrison Kathleen , Hwang Il-Young , Nabar Neel R. , Wang Min , Kehrl John H.
Published: September 2020

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.

Social distancing and physical distancing policies have been implemented in many countries for some time in the face of a COVID-19 pandemic. The new policy that has been adopted by many countries is "New Normal". New Normal is a scenario to accelerate the handling of COVID-19 in health and socio-economic aspects. One of them is the Government of Indonesia has announced plans to implement new normal scenarios by considering epidemiological studies and regional readiness. With the implementation of New Normal, education will be run again according to the health protocol. New Normal policies in education must also be in line with instructions issued by The United Nations Agency for Child Welfare (UNICEF). UNICEF has issued guidelines for countries that want to reopen teaching and learning activities in schools. The guide consists of three stages, namely before opening, entering the opening process, and when opening has been carried out. Research on the planning, preparation, implementation, and evaluation of New Normal in the field of learning and teaching needs the attention of all parties, including academics.

Authors: BHATTI FIAZ AHMAD
Published: September 2020

In this paper, a flexible distribution with increasing, bathtub and inverted bathtub hazard rate called Modified Burr III-Power (MBIII-Power) is developed on the basis of the generalized Pearson differential equation. The density function of MBIII-Power is arc, exponential and positively skewed shaped. Descriptive measures such as quantiles, moments, incomplete moments, inequality measures, residual life functions and reliability measures are theoretically established. The MBIII-Power distribution is characterized via different techniques. Parameters of MBIII-Power distribution are estimated using maximum likelihood method. The simulation study is performed to illustrate the performance of the maximum likelihood estimates (MLEs). Potential use of MBIII-Power distribution is demonstrated by its application to two data sets: serum-reversal time (in days) of children born from HIV-infected mothers and failure times of device data.

Published: September 2020

Article discusses the problem of heuristic teaching method of mathematics started from 19th centuries. Here was substantiated the thesis that the heuristic method of teaching is one of the most important methods of teaching mathematics. The works of scientists from different countries were studied. Based on the analysis of S.M. Jubran and other researchers, the level of necessity of this training method is established.          This article attempts to reveal the system of pedagogical skills of a teacher in heuristic teaching of mathematics. Here was shown pedagogical skills which are necessary for organizing and managing students ' heuristic activities and fully describe the stages of the educational process (by O.A. Bulvinskaya).          In order to determine the conception of heuristic teaching method among teachers of Kazakhstan there was made a Likert scale questionnaire of 13 items. These 13 items were taken from 13 heuristics, that were identified by the Curriculum Planning and Developing Division (CPDD) within the Ministry of Education Singapore (MOE).

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.

Authors: Davydov A. , Larionov A. , Nagul N.
Published: September 2020

The paper considers how methods of a logical inference search in the calculus
of positively constructed formulas may be applied to represent and study discrete event systems. The formalisms of discrete event systems and positively constructed formulas are briefly described. A method for constructing a product of automata using constructive inference in the positively constructed formulas calculus is proposed. Based on the given specication on
the behaviour of the system, a method for constructing a supremal controllable sublanguage of the specication is presented.
Tender of computational works in heterogeneous distributed environment

Nowadays, applying various market-based methods for regulating supply and demand of resources for distributed computing is becoming increasingly relevant. In particular, different forms of standard auctions are actively used. However, their basic capabilities often do not enable to fully solve the complicated problems of resource allocation in a heterogeneous distributed computing environment. In this regard, a tender of computational works based on a combinatorial Vickrey auction has been designed. It is applied within multi-agent computing management. For the tender, new models are proposed to rank the criteria of resources owners and users. The tender use advantages are shown in comparison with traditional meta-schedulers.
System for monitoring parameters of functioning infrastructure objects and their external environment

The paper addresses relevant issues applying the concept of Industry 4.0 in related to modeling infrastructure objects at the Baikal natural territory that use environmentally friendly technologies. In particular, the use of heat pumps belongs to such technologies, since this enables us to reduce air emissions. Object models are designed on the basis of their digital twins. Digital twins are intended to reflect the structure and processes of object functioning. In addition, we plan to delegate them the decision-making in managing these objects in real-time. Such a digital twin has to become smarter over time. This virtual entity has to gain knowledge and skills to select optimal scenarios for controlling object and improving its functioning parameters. Therefore, the initial problem in its development is creating a monitoring system for the collection, unification, aggregation, storage, and transmission of subject-oriented data. Such data include information about the object operation and environmental state. The data must be promptly obtained from peripheral equipment (controlling and measuring devices). For the effective operation of a digital twin, we have to partially transfer functions of primary data processing, their intellectual analysis and decision-making to the controlling and measuring devices. To this end, we use agents that implement software on peripheral equipment.
On polynomial reduction of problems based on diagonal Latin squares to the exact cover problem
Authors: Vatutin E. , Nikitina N. , Belyshev A. , Manzyuk M.
Published: September 2020

The paper discusses the reduction of problems based on Latin squares to the exact cover problem aiming at its subsequent solution using the dancing links algorithm. The former problems include generation of Latin squares and diagonal Latin squares of a general form/with a given normalization, generation of orthogonal Latin and diagonal Latin squares directly/through the set of transversals, obtaining a set of transversals for a given square, forming a subset of disjoint transversals. For each subproblem, we describe in detail the process of forming the corresponding binary coverage matrices. We show that the use of the proposed approach in comparison with the classical one, i.e. the formation of sets of transversals and their coverages using exhaustive enumeration, allows one to increase the eective processing pace of diagonal Latin squares by 2.5{5.6 times. The developed software implementations of the algorithms are used in computational experiments as part of the Gerasim@Home volunteer distributed computing project on the BOINC platform
O Tempo Integral na Visão dos Alunos de uma Escola Pública do Ceará

Published: September 2020

A implementação das Escolas de Ensino Médio em Tempo Integral (EEMTI) na Rede Estadual do Ceará ocorreu no ano de 2016, realizada pela Secretaria de Educação Básica do Ceará (SEDUC). Tal política vem acarretando mudanças no cotidiano das escolas onde o tempo integral vem sendo implantado e também na vida dos alunos. Neste artigo, analisamos as mudanças ocasionadas pela implantação do Tempo Integral na escola Jociê Caminha de Meneses a partir da percepção dos alunos. Para tal, foi realizada uma pesquisa de campo na referida escola, com alunos dos 3º anos do Ensino Médio em Tempo Integral. Os participantes responderam a perguntas por meio de questionários e entrevistas emitindo suas opiniões sobre o regime de Tempo Integral. Entre os pontos elencados pelos jovens destacam-se aspectos positivos (a relação harmoniosa entre professores e alunos e a criação das disciplinas Eletivas como ferramenta importante no processo de ensino-aprendizagem) e aspectos que precisam ser melhorados: a infraestrutura da escola, a qualidade da alimentação e a participação da comunidade escolar no processo de implantação das políticas públicas dentro de uma escola.

Nos últimos anos intensificaram-se os debates acerca da inserção dos temas transversais propostos pelos PCNs para serem trabalhados de forma interdisciplinar. Esta pesquisa objetivou analisar se as políticas culturais implementadas pela Secretaria de Cultura que estão sendo desenvolvidas em uma escola de ensino fundamental de Juazeiro do Norte, durante 2018. A pesquisa é qualitativa tendo como ferramenta analítica coleta e produção de dados, estudos bibliográficos: Vieira (2008); Ney (2008); Secchi (2016) e documental: Plano Municipal de Cultura, Projeto Político Pedagógico da escola, além de entrevistas semiestruturadas com os professores, Núcleo Gestor e secretária de educação de Juazeiro. Quanto às atividades desenvolvidas na escola somente dois projetos foram desenvolvidos: “São João integrador” e “Folclore das Regiões do Brasil”. Constatou-se que a cultura local é trabalhada em sala de aula de forma pontual e em datas específicas e os professores não percebem mudanças significativas na instituição com a implementação da política pública vigente, embora o processo tenha envolvido toda comunidade escolar. A interdisciplinaridade entre História, Geografia e Artes, não acontece com propriedade na prática. Quanto aos segmentos culturais do PMC: artes cênicas, música, literatura, artes visuais, artesanato, audiovisual, patrimônio cultural e cultura popular, não parece ser de conhecimento da comunidade escolar, nem tampouco dialoga com o PPP da escola. Os planejamentos dos professores acontecem semanalmente, por área de conhecimento, enquanto as formações não são continuadas, acontecem mensalmente, bimestralmente ou semestralmente. Os resultados encontrados apontam que os objetivos propostos pela transversalidade enquanto desafio epistemológico, ainda não atingiu total êxito na organização e prática do currículo da escola pesquisada.
