Sistema Selecionador de Recursos Computacionais de Grade baseado na Interoperabilidade de Múltiplas Ontologias
Authors: Silva A. P. C. , Dantas M. A. R.
Published: March 2022

O paradigma de grade computacional tem como uma das suas principais características o compartilhamento de recursos heterogêneos espalhados geograficamente por diversas organizações virtuais. No entanto, o processo de seleção destes recursos toma-se na prática difícil, pois as organizações apresentam visões distintas quanto à forma de descrever seus recursos. Desta forma, em um sistema de seleção de recursos em grades é desejável realizar comparações semânticas. Neste artigo, propomos um sistema selecionador de recursos que considera diferentes visões que as organizações podem apresentar. Este sistema apoia-se na abordagem de integração híbrida sobre regras semânticas para alcançar a interoperabilidade entre as diversas ontologias. Resultados experimentais práticos indicam que o sistema alcançou com sucesso o objetivo.
Utilizando Adaptação Consciente da Aplicação No Acesso a Arquivos em um Ambiente Pervasivo

Published: March 2022

O Espaço Pervasivo de Arquivos (EPA) é um serviço do middleware EXEHDA que provê acesso a arquivos de forma a implementar o conceito de semântica 'siga-me' das aplicações pervasivas. Esse serviço introduz um novo modelo para adaptação ciente da aplicação que fornece métodos para que as aplicações provejam informações específicas para guiar a adaptação ou estendam o EPA com módulos de aplicação que podem se adaptar a novos elementos de contexto. A combinação dessas duas estratégias permite que o modelo do EPA ultrapasse muitas das limitações apresentadas em trabalhos sobre sistemas de arquivos para computação pervasiva.
Analisando a Predição de Desempenho com os Modelos Analíticos Gerados pela Metodologia PEMPIs-Het
Authors: Laine Jean Marcos , Midorikawa Edson Toshimi
Published: March 2022

Com o crescente uso da computação distribuída em ambientes heterogêneos, principalmente para processamento de alto desempenho, fica cada vez mais evidente a necessidade do desenvolvimento de metodologias e ferramentas específicas para análise, avaliação e predição de desempenho nestes ambientes. Embora existam vários trabalhos que propõem metodologias para este propósito, pouco ainda tem sido feito em ambientes heterogêneos. Motivados pela importância desta linha de pesquisa na computação de alto desempenho, desenvolvemos uma metodologia chamada PEMPIs-Het que faz uso de meta-modelos analíticos para modelar e estimar o desempenho de aplicações paralelas MPI em sistemas como clusters e grids computacionais. Neste artigo, avaliamos a aplicabilidade das técnicas que compõem a metodologia e a precisão das estratégias, tanto na predição de desempenho quanto na distribuição de cargas computacionais. Os resultados experimentais obtidos comprovaram a eficácia da modelagem e de sua aplicação na distribuição de carga em um estudo de caso realizado.

Vertragliche und außervertragliche Haftung für den Einsatz von Softwareagenten
Authors: Weingart Rowena Angelika
Published: March 2022

Since the ability of software agents to act autonomously is also the cause of autonomous malfunctioning, a legal framework has to regulate compensation for damages caused by autonomous malfunctioning. Appropriate regulation already exists in both contractual and pre-contractual settings; however, it does not exist regarding non-contractual liability. This situation encourages uneconomic and abusive behavior and prevents efficient use of autonomous software. A solution for this problem is a joint and several strict liability, combined with an additional mandatory insurance for software that is particularly prone to danger.
Rechtliche Zulässigkeit von Salary Caps im Fußballsport
Authors: Hahn Thilo
Published: March 2022

In professional football, clubs partly pay such high player salaries that they themselves get into financial difficulties; furthermore, the economic and competitive imbalance between the clubs has been steadily increasing in recent years. Salary caps or luxury taxes, well-known from US-sports, are repeatedly proposed as a solution to these problems. In the discourse, though, salary caps are often described as being illegal. However, many different salary cap systems exist – even in the US-leagues. This book examines their legality in a differentiated manner, focusing on EU antitrust law and German collective bargaining law.
Recht auf Vergessenwerden
Authors: Heilmann Dorothea
Published: March 2022

Dangers to the general right of personality protected by fundamental rights emanate not only from the media, but increasingly also from search engines. The potential for infringement is much greater than in the analog era, because the "Net forgets nothing" and infringements of personality rights are ubiquitous for everyone and at any time. Article 17 of the GDPR does constitute a right to be forgotten, but the provision does not specify the criteria to be applied. In this respect, the work deals with the question of whether a harmonization of the balancing system under data protection law with the balancing system under the law of expression is necessary in the case of delisting claims against search engines.
Die Strafbarkeit der Marktmanipulation unter dem europäischen Marktmissbrauchsregime
Authors: Richter Thomas
Published: March 2022

This book examines the criminal liability for market manipulation pursuant to section 119 of the German Securities Trading Act (WpHG) under the European market abuse regime in force as of 2016. The changes in criminal liability brought about by European norms are analysed coherently. A legal comparison with EU countries reveals that the requirement of price impact is a special feature of the German offence. The book closely examines a new qualification of a crime, which raises unresolved questions as to its preconditions and has important consequences for criminal proceedings. Practising as a criminal defence lawyer, the author has a wealth of experience in capital markets criminal law and places particular emphasis on practical insights.
Innovation Competition
Authors: Kurz Katrin Silja
Published: March 2022

The thesis addresses the interplay between innovation incentives and competition. In its Dow/DuPont merger control decision, the European Commission based far-reaching remedies on the newly developed concept of innovation competition. The concept refers to the parties' general ability to innovate independently of identifiable products or specific research and development activities. The author places the concept of innovation competition in a broader context and examines the applicability of the underlying considerations in the context of Articles 101 and 102 TFEU.

Published: March 2022

The recent development of whole-genome sequencing technologies paved the way for understanding the genomes of microorganisms. Every whole-genome sequencing (WGS) project requires a considerable cost and a massive effort to address the questions at hand. The final step of WGS is data analysis. The analysis of whole-genome sequence is dependent on highly sophisticated bioinformatics tools that the research personal have to buy. However, many laboratories and research institutions do not have the bioinformatics capabilities to analyze the genomic data and therefore, are unable to take maximum advantage of whole-genome sequencing. In this aspect, this study provides a guide for research personals on a set of bioinformatics tools available online that can be used to analyze whole-genome sequence data of bacterial genomes. The web interfaces described here have many advantages and, in most cases exempting the need for costly analysis tools and intensive computing resources.

Published: March 2022

2-Methoxy-1,4-naphthoquinone (MNQ) has been shown to cause cytotoxic towards various cancer cell lines. This study is designed to investigate the regulatory effect of MNQ on the key cancer genes in mitogen-activated protein kinase, phosphoinositide 3-kinase, and nuclear factor кB signaling pathways. The expression levels of the genes were compared at different time point using polymerase chain reaction arrays and Ingenuity Pathway Analysis was performed to identify gene networks that are most significant to key cancer genes. A total of 43 differentially expressed genes were identified with 21 up-regulated and 22 down-regulated genes. Up-regulated genes were involved in apoptosis, cell cycle and act as tumor suppressor while down-regulated genes were involved in anti-apoptosis, angiogenesis, cell cycle and act as transcription factor as well as proto-oncogenes. MNQ exhibited multiple regulatory effects on the cancer key genes that targeting at cell proliferation, cell differentiation, cell transformation, apoptosis, reduce inflammatory responses, inhibits angiogenesis and metastasis.
Experimental development of the epigenomic library construction method to elucidate the epigenetic diversity and causal relationship between epigenome and transcriptome at a single-cell level
Authors: Park Kyunghyuk , Jeon Min Chul , Kim Bokyung , Cha Bukyoung , Kim Jong-Il
Published: March 2022

The method of single-cell RNA sequencing has been rapidly developed, and numerous experiments have been conducted over the past decade. Their results allow us to recognize various subpopulations and rare cell states in tissues, tumors, and immune systems that are previously unidentified, and guide us to understand fundamental biological processes that determine cell identity based on single-cell gene expression profiles. However, it is still challenging to understand the principle of comprehensive gene regulation that determines the cell fate only with transcriptome, a consequential output of the gene expression program. To elucidate the mechanisms related to the origin and maintenance of comprehensive single-cell transcriptome, we require a corresponding single-cell epigenome, which is a differentiated information of each cell with an identical genome. This review deals with the current development of single-cell epigenomic library construction methods, including multi-omics tools with crucial factors and additional requirements in the future focusing on DNA methylation, chromatin accessibility, and histone post-translational modifications. The study of cellular differentiation and the disease occurrence at a single-cell level has taken the first step with single-cell transcriptome and is now taking the next step with single-cell epigenome.

Published: March 2022

The two complete mitochondrial genomes (mitogenomes) of Paedocypris progenetica, the smallest fish in the world which belonged to the Cyprinidae family, were sequenced and assembled. The circular DNA molecules of mitogenomes P1-P. progenetica and S3-P. progenetica were 16,827 and 16,616 bp in length, respectively, and encoded 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes, and one control region. The gene arrangements of P. progenetica were identical to those of other Paedocypris species. BLAST and phylogenetic analyses revealed variations in the mitogenome sequences of two Paedocypris species from Perak and Selangor. The circular DNA molecule of P. progenetica yield a standard vertebrate gene arrangement and an overall nucleotide composition of A 33.0%, T 27.2%, C 23.5%, and G 15.5%. The overall AT content of this species was consistent with that of other species in other genera. The negative GC-skew and positive AT-skew of the control region in P. progenetica indicated rich genetic variability and AT nucleotide bias, respectively. The results of this study provide genomic variation information and enhance the understanding of the mitogenome of P. progenetica. They could later deliver highly valuable new insight into data for phylogenetic analysis and population genetics.
MPI-GWAS: a supercomputing-aided permutation approach for genome-wide association studies
Authors: Paik Hyojung , Cho Yongseong , Cho Seong Beom , Kwon Oh-Kyoung
Published: March 2022

Permutation testing is a robust and popular approach for significance testing in genomic research that has the advantage of reducing inflated type 1 error rates; however, its compu-tational cost is notorious in genome-wide association studies (GWAS). Here, we developed a supercomputing-aided approach to accelerate the permutation testing for GWAS, based on the message-passing interface (MPI) on parallel computing architecture. Our application, called MPI-GWAS, conducts MPI-based permutation testing using a parallel computing approach with our supercomputing system, Nurion (8,305 compute nodes, and 563,740 central processing units [CPUs]). For 107 permutations of one locus in MPI-GWAS, it was calculated in 600 s using 2,720 CPU cores. For 107 permutations of ~30,000–50,000 loci in over 7,000 subjects, the total elapsed time was ~4 days in the Nurion supercomputer. Thus, MPI-GWAS enables us to feasibly compute the permutation-based GWAS within a reason-able time by harnessing the power of parallel computing resources.
Philosophy, Academic and Public
Authors: Wallis Jacqueline Mae , Detlefsen Karen ,   Philosophy Documentation Center
Published: March 2022

In 2020, the University of Pennsylvania instituted a graduate certificate in public philosophy. In many ways, this certificate formalized and recognized the public engagement work that graduate students in the philosophy department and beyond had been involved with for some years. One element of the certificate, however, was pivotal in moving our work in public philosophy forward in important ways. This element is the research seminar in public philosophy. In this paper, we recount the motivation for the creation of the certificate and especially the motivation for the inclusion of the research seminar. We also explore ways in which such a certificate, along with the deliberately self-reflective work of the research seminar, might help us reimagine the nature and value of philosophy and its connection with human life and flourishing. We focus on metaphilosophical themes such as the very nature of philosophy and the philosopher as well as the importance of cultivating a new generation of academic philosophers committed to transcending the distinction between the academy and the public and, relatedly, between academic philosophy and public philosophy.
Platygonia Melichar, 1925 (Insecta: Hemiptera: Cicadellidae: Cicadellini): a new species from the Brazilian Amazon Rainforest, key to species of the genus, and notes on P. undecimmaculata (Fowler, 1899)

Published: March 2022

A new species of the Neotropical genus Platygonia Melichar, 1925 is described and illustrated from the municipality of Ipixuna, State of Amazonas, Northern Brazil. Platygonia nigra sp. nov. can be distinguished from the other species of the genus by the following combination of features: (1) dark brown to black ground color of dorsum; (2) presence of a white to pale yellow spot at the distal portion of corium; (3) male pygofer with a conspicuous diagonal cleft; (4) connective Y-shaped, keeled, with the stem longer than the arms; and (5) aedeagus with an unpaired basiventral process directed anteriorly. This is the first record of the genus from the Brazilian Amazon Rainforest. Notes on P. undecimmaculata (Fowler, 1899), which is a taxon of uncertain taxonomic position, a key to the species of Platygonia, and a map showing their distribution are added.
Listening, acting and changing UK policy with children: learning from European examples and theories of children�s agency
Authors: Larkins Cath
Published: March 2022

Recent developments suggest increasing European receptiveness to children�s involvement in policymaking, which has some resonance with practice in the UK. Individually and collectively, children are sometimes involved, usually at earlier stages of the policy cycle, but inclusiveness of marginalised children and resulting impact are often lacking. Exploring examples provides ways of questioning which children are being listened to, when, how and with what results in terms of action and change. Using relational accounts of agency can give insight into the relationships between people and environments that may be facilitative of children�s collective and individual influence.

Heavy vehicle traffic, especially large military combat vehicles, causes soil compaction, which reduces their physical quality and increases their susceptibility to soil erosion. A large contingent of the Brazilian Army conducts combat vehicle training at the Santa Maria Instruction Field (CISM), which has been caused degradation of the ecosystem. The aim of this study was to evaluate the effect of combat vehicle Leopard 1A5BR traffic on soil physical properties in an Abruptic Alisol with military vehicle traffic history. Two types of maneuvers were evaluated: (i) straight traffic with 0, 1 and 3 passes, and (ii) pivoting maneuver with 0, 1 and 2 pivots. Soil morphology, particle size distribution and organic carbon content were analyzed in the 0.00-0.10 and 0.20-0.30 m layers. Bulk density, total porosity, macroporosity, microporosity, saturated soil hydraulic conductivity, penetration resistance and preconsolidation pressure were evaluated in the 0.00-0.04, 0.10-0.14 and 0.20-0.24 m layers. The preconsolidation pressure of the surface layer indicated that the soil surface layer is susceptible to traffic compaction of Leopard 1A5BR. Only one pass (straight traffic) and one pivoting maneuver were sufficient to increase soil penetration resistance and bulk density and reduce the total porosity and macroporosity in the surface layer (0.00-0.04 m).

Vegetative growth can be affected by different environmental factors. The objective of this work was to evaluate phytomass production and photosynthetic pigments of Aloysia citrodora plants submitted to different irrigation levels and seasons. The experiment was carried out in a protected environment from August 2015 to March 2017, in an experimental randomized blocks design, 4x4 factorial scheme, with four blocks with four plants each. The irrigation levels tested were 25%, 50%, 75% and 100% of the field capacity, in the four seasons of the year (autumn, winter, spring and summer). Plant height, fresh and dry mass of branches, fresh and dry mass of leaves, leaf area and photosynthetic pigments (chlorophyll a, chlorophyll b and carotenoids) were evaluated. It was observed that water availability and seasons influence phytomass production as well as the photosynthetic pigment analyzes. Low irrigation levels and cultivation during autumn and winter adversely affect vegetative growth. Furthermore, our results indicate that for higher phytomass production, it is recommended to cultivate Aloysia citrodora during spring and summer under irrigation levels of 75% and 100% of field capacity. Spring season promotes higher content of photosynthetic pigments. This study will open new avenues and perspectives to elucidate possible changes in secondary metabolites of Aloysia citrodora, a medicinal plant, in the presence of changes in the growing seasons and different stress conditions, including water stress.

Published: March 2022

The knowledge of the diversity of free-living protozoa in aquatic ecosystems represents an important tool in environmental quality management. It has been widely used in studies evaluating the water quality of fresh-water sources with environmental variables. Therefore, this study aimed to verify the diversity of free-living protozoa in two water sources used as a public supply for human consumption in the municipality of Blumenau, SC, for 12 months. Water samples were collected monthly for analysis of environmental variables and for identification of organisms. In total, 39 taxa were recorded in P1 and P2, both in the readings performed on the day of collection and in the cultivation. In P1, 11 taxa were identified in the readings of the day of collection, and after reading the cultivation, 20 new taxa were recorded.  P2 presented 12 taxa in the readings performed on the day of collection and 10 new taxa in the cultivations' readings. Ciliates were the most expressive group in the period, with 69.5% frequency in P1 and 66.1% in P2. The results of the environmental variables in conjunction with the survey of the free-living protozoa of P1 and P2 did not show marked differences between the points. Still, they contributed to the knowledge of the diversity of protozoa in aquatic environments.

O fogo no Brasil é associado a diversas etapas do setor agropecuário, sendo frequente o registro de incêndios e queimadas no país. Assim, o Maranhão, é um dos estados com maior ocorrência de focos de queimadas. O objetivo deste trabalho foi analisar a dinâmica espacial e temporal dos focos de calor no   Maranhão. Os dados de focos de calor foram adquiridos no Instituto Nacional de Pesquisas Espaciais, enquanto os de pluviosidade com o sensor TRMM. Analisou-se os focos de calor anualmente, entre 2007 a 2019. Estes foram submetidos ao estimador de densidade Kernel no QGIS 2.18. Houve 325.940 focos no Maranhão entre 2007 a 2019, com maior incidência em 2007. A maior precipitação ocorreu entre janeiro e maio, o que coincide com a menor incidência dos focos de calor. Estes estão concentrados no centro maranhense, onde há menor precipitação. Os focos estavam entre 0-149 km de áreas de desmatamento, assentamentos, rodovias e aldeias indígenas. As áreas com maior concentração dos focos de queimadas estão localizadas no bioma cerrado, sendo a maior incidência no segundo semestre, o qual tem menor pluviosidade. Portanto, a incidência dos focos de calor é intrínseca à sazonalidade da precipitação e intensificada pela ação antrópica.
Impacts of the ocean-atmosphere coupling into the very short range prediction system, during the impact of Hurricane Matthew on Cuba

Published: March 2022

The main goal of this investigation is analyzing the impact of insert the ocean-atmosphere coupling into the very short range prediction system of Cuba. The ocean-atmosphere coupled components of the Coupled Ocean-Atmosphere-Wave-Sediment Transport Modeling System are used for this purpose and the hurricane Matthew is selected as study case. Two experiments are performed: first, using a dynamic sea surface temperature, updated daily in the atmospheric model WRF; and second using a dynamic coupling between the atmospheric and an oceanic models. For the simulated track, the best results are obtained with the coupled system. The impact of coupling on the maximum wind velocities and minimum central pressure is studied. In the coupled system the sea surface temperature has more influence in the surface latent heat fluxes. Also, with this methodology the dry footprint and the behavior of the precipitation field in the presence of a hurricane are studied. This analysis shows that the hurricane acts like an open and self-sustained system in the numerical experiments. The highest differences in the precipitation simulations are in the significant convective area inside the hurricane.

Objetos e matéria: em busca de uma possível fotograficidade singular
Authors: Fonseca Darci Raquel
Published: March 2022

Objetos & Matéria compreende uma série de fotografias realizadas com o telefone celular, dispositivo que, usado como meio de realização e busca de uma possível poética dos objetos do cotidiano, por estar sempre à mão, disponibiliza uma proximidade com o objeto da presente pesquisa. Uma experiência que leva a pensar a articulação deste objeto cultural sem arte, na esfera da arte contemporânea. É certo dizer que o telefone celular ocupa um lugar a não ser negligenciado na comunicação e em diversos projetos artísticos atuais. Observamos que sua função primeira, a comunicação pela fala, se comparada a de produção de imagens, é hoje largamente reduzida. A tecnologia digital oferece cada vez mais condições para que o aparelho móvel possa ser usado em diversas aplicações, entre elas, a da criação artística visual. É certo também que o utilizador do dispositivo móvel se confronta com a predeterminação científica de fabricação deste objeto cultural, demandando um entendimento de condição, para que se possa contorná-la e, por conseguinte, obter a fotograficidade desejada para a foto em realização, pois é neste processo que o trabalho é determinante para o resultado esperado. Pensando com Flusser, os objetos culturais foram organizados intencionalmente, e  cada um ajusta o olhar do fotógrafo em sua busca. Ainda com Flusser, o fotógrafo se esgueira entre os objetos, para evitar a intenção que neles se esconde, a fim de se emancipar de sua condição cultural. Na tentativa de transmutação dos objetos culturais da vida cotidiana para a cena artística, buscamos caminhos que os revelem mais surpreendentes do que belos. A mise en œuvre que articula os objetos sem arte no campo da arte visa uma articulação de suas realidades, a partir de conteúdos sensíveis que se encontram para além da materialidade que os constitui; esses objetos fotografados comportam algo da vida cotidiana que nos toca e que, de uma maneira ou de outra, nos  emociona. Conforme diz Edgar Morin, a fotografia corteja os sentimentos. Clarividente, ela se abre no invisível. Portanto, os objetos vistos, mais do que ver, nos fazem sentir o que a representação exalta visualmente como essência. Traço da realidade, a fotografia resulta de uma excepcional conjunção do real com elementos impalpáveis que emergem do ato de representação que a faz singular.
As fronteiras que esBARRAm as produções artístico-culturais contemporâneas da exterioridade
Authors: Bessa-Oliveira Marcos Antônio
Published: March 2022

A fronteira é espaço de exterioridades: de arte, de culturas e de conhecimentos que não foram grassados nos modelos estabelecidos pelo Projeto Moderno Europeu (séc. XIV/XV). Portanto, viver em estado de fronteira é ser/ter coisas que (es)barra(m) a circulação de arte, culturas e os conhecimentos produzidos em lugares de exterioridades à interioridade dos pensamentos hegemônicos. Assim, a discussão descolonial aqui se edifica em refletir as “fronteiras” (im)postas à arte do agora pelos discursos que barram!

Gravura e a poética do múltiplo: diálogos entre um processo de criação contemporâneo e a cultura do consumo
Authors: Ladeira Marcillene
Published: March 2022

RESUMO: O presente artigo traz o recorte de uma fundamentação teórico-prática, na qual a palavra-imagem “múltiplo” é instaurada como um dos argumentos poéticos empregado nas obras autorais da artista-pesquisadora Marcillene Ladeira. Neste transcurso, apresenta-se a gravura como ponto de partida, pois a esta linguagem – conforme consenso à farta de pesquisadores – originalmente reserva-se tal conceituação. Em adição ao processo de construção plástica, estão a pintura e a fotografia, em retratação “do real” e submergidas em características híbridas. Como referencial de artistas e obras, empregam-se: Andy Warhol, com as obras “Brilho Box” (1964) e “Lata de sopa Campbell” (1964) e Daniel Arsham, com “Eroded Brillo Box” (2019/2020). Quanto aos autores, há destaques para: Benjamin (1955), Costella (2006), Entler (2007), Catarxo (2012) e Foster (2017). Sustenta-se que o múltiplo – entendido enquanto possibilidade de reprodução “numa espécie de linha de montagem” – permitiu estabelecer diálogos profícuos de pensamento. Em uma leitura de aproximação com a Pop, mas com uma envergadura diferenciada, as obras em discurso, transitam do imaginário do consumo para o pós-consumo, cuja poética instaurada entre “arte e meio ambiente”,  sustenta-se por três conceitos operacionais chave: “liquidez”, “respeito à natureza” e “transitoriedade, enquanto seres viventes”. As relações dialógicas estabelecidas no lugar da exposição também, são evidenciadas como estratégia pessoal de produção e singularidade desse fazer, sobre a égide da interfase: múltiplo-lugar-poética.

A través de la escritura, se discuten las asociaciones visuales de una convalecencia covideana. El principal objetivo es establecer relaciones entre los grados de percepción del mundo y de una misma. Son evocadas también las acciones y modos de sobrevivencia en casa durante la pandemia vivida en el año de 2020 y 2021. Se utilizan los fundamentos del perspectivismo de Eduardo Viveros de Castro (2018) y los presupuestos de la escritura de Marguerite Duras (1993). El resultado es una poética perceptiva y silenciosa marcada por las huellas de las visiones suscitadas durante un estado covideano, retrospectivamente afectivo.
Perceptual and number effects on students’ initial solution strategies in an interactive online mathematics game
Authors: Lee Ji-Eun , Hornburg Caroline Byrd , Chan Jenny Yun-Chen , Ottmar Erin
Published: March 2022

This study investigated the effects of 1) proximal grouping of numbers, 2) problem-solving goals to make 100, and 3) prior knowledge on students’ initial solution strategies in an interactive online mathematics game. In this game, students transformed an initial expression into a perceptually different but mathematically equivalent goal state. We recorded students’ solution strategies and focused on the productivity of their first steps—whether their initial action led them closer to the goal. We analyzed log data within the game from 227 middle-school students solving four addition problems and four multiplication problems consisting of a total of 1,816 problem-level data points. Logistic regression modeling showed that students were more likely to use productive initial solution strategies to solve addition and multiplication problems when 1) proximity supported number grouping, 2) 100 was the problem-solving goal, and 3) students had higher prior knowledge in mathematics. Furthermore, when problem-solving goals were non-100s, students with lower prior knowledge were less likely to use productive initial solution strategies than students with higher prior knowledge. The findings of the study demonstrated that perceptual and number features influenced students’ initial solution strategies, and the effect of number features on initial solution strategies varied by students’ prior knowledge. Results yield important implications for designing instructional activities that support mathematics learning and problem-solving.

A SARS-Cov2 se desenvolve mediante células epiteliais das vias aéreas humanas, utilizando células de enzima conversora angiotensina 2 (ACE2) como receptora, se instalando no organismo humano de forma muito rápida, devido a presença da proteína Spike que entra nas células hospedeiras dessa forma a infeção se instala no momento que se possui a infecção do trato respiratório inferior. A protease transmembranar é a enzima codificada pelo gene TMPRSS2 em seres humanos que auxilia na homeostase um agente hospedeiro vital na contaminação da COVID-19. O SARS-CoV-2 entra nas células através de difusão pela membrana retardando a regulação da ACE2, após o retardo da ACE2 e ao entrar se inicia o processo de replicação e depois pela etapa multiplicativa. O objetivo desse artigo é demonstrar as características genéticas do Sars-Cov-2. Diante disso, foi realizado uma pesquisa descritiva e exploratória, de abordagem qualitativa e o levantamento bibliográfico foi realizado nas bases de dados: sciELO, Pubmed, Associações Internacionais, com os descritores coronavírus, genética, fisiopatologia. O coronavírus em conjunto com a COVID-19 possui75 - 80% de semelhança com o coronavírus da SARS-CoV (síndrome respiratória aguda grave) e através do processo de infecção proteases são liberadas, criando espécies reativas de oxigênio (ROS) nas células hospedeiras que são toxicas para o sistema celular, fazendo com que o sistema imunológico ativo os mecanismos de defesa

Augmented Reality (AR) is an enhanced version of reality created by the use of technology to overlay digital information on an image of something being viewed through a device. AR has potential uses in many fields such as education, retail, repair/maintenance, manufacturing, and gaming. Any well-conducted and well-planned product development project should follow an iterative human-centered process. Throughout the development lifecycle, usability evaluations should be conducted to ensure that the product can be used by specified users to achieve specified goals with effectiveness, efficiency, and satisfaction in a specified context of use. This AR Usability Evaluation Framework provides guidance on planning user-based usability evaluations of AR technology. While this report demonstrates the framework using a firefighting scenario in the public safety domain, the framework is applicable and can be expanded to other domains where users-based AR usability evaluations will be performed. Applying the framework in AR development lifecycles will provide the following benefits: Creating explicit structures for user-based evaluations Providing a consistent terminology and an initial set of usability metrics Facilitating comparability across AR research and development efforts Facilitating sharing of usability evaluation results Facilitating establishing human-centered AR design guidelines This report provides a five-component AR Usability Evaluation Framework to facilitate planning usability evaluations systematically to ensure successful evaluations and collecting useful usability data for product improvement. It will help reduce development cost and bring the product faster to market while providing good usability for users that are easy, quick, comfortable, and safe to use with minimal errors.
Mujeres cineastas: entre la reivindicación y el reconocimiento

Published: March 2022

Cuando Neus Ballús recogió el Premio Gaudí 2022 a la mejor película dijo que «las mujeres no sólo hemos llegado al cine para hacer óperas primas: hemos venido para quedarnos». Esta frase sintetiza un proceso de más de veinte años en los que hemos vivido un cambio generacional en el cine español que ha ido de la mano de la incorporación, visibilización y reconocimiento de las mujeres en el sector cinematográfico.
The presidential campaign of 1965 in France: features of the conduct and motives of the voters' vote
Authors: Atakishieva Dzhamilya Gunduz Kyzy
Published: March 2022

The subject of this study is the first general presidential election of the Fifth Republic in 1965. This is one of the key events of the presidency of General Charles de Gaulle, since for the first time since the adoption of the constitutional amendment on October 28, 1962, the elections of the head of state of France have acquired the status of universal popular vote. This presidential campaign is of particular research interest due to the fact that de Gaulle, the leader and savior of the French nation, failed to immediately collect a majority of votes in the first round of voting. Did the General's failure mark the transformation of the political behavior of the French people? And if so, why did this happen? In order to answer these questions, the author studies the peculiarities of the election campaign and the motives of the voters, which is the object of the study. There is no denying that the presidential campaign of 1965 has already been the subject of research in the works of Western scientists who appeared in the first few years after the elections, it is also described in general works on the Degoll presidency. At the same time, the influence of the peculiarities of the 1965 election campaign on the choice of voters did not become a separate topic of study. The main conclusion of this article is that the change in the motives of the French vote was associated with the new economic situation, with a new generation of young voters - children of the war era and the occupation of France. Also, the choice of the people was influenced by the widespread use of modern propaganda methods, primarily television. De Gaulle was "blackballed" in the first round largely due to the fact that he initially refused to use the possibilities of new ways of propaganda, did not at all create a more attractive, understandable image to voters, believing that his previous merits would be enough to win.
Duets by Anna Karenina and Alexey Vronsky in the ballet by J. Neumeier's "Anna Karenina": features of the author's interpretation of the images of the main characters
Authors: Khokhlova Daria
Published: March 2022

This article continues the author's research devoted to the study of the problem of choreographic interpretations of literary works, in particular, John Neumeier's ballet "Anna Karenina". In this work, the identification of expressive staging means and choreographic elements used by Neumeier in the production of duets by Anna Karenina and Alexei Vronsky is carried out in order to determine the place of these choreographic fragments in the performance, as well as their significance for the author's interpretation of the images of the main characters of the novel by Leo Tolstoy. In the course of the research, the author applied comparative-historical, ideological-artistic and analytical methods, as well as the method of included observation (based on personal experience of working with Neumeier on Kitty's party). In the course of the source analysis, video materials from the archives of the Hamburg Ballettzentrum and the Moscow Bolshoi Theater were used, as well as lectures conducted by Neumeier before the Moscow premiere of Anna Karenina (recordings from the author's archive). A detailed analysis of the dance score of three duets by Anna and Vronsky revealed traditional and innovative author's solutions related to the new research results. So, Neumeier uses such staging means as the compilation of Tchaikovsky and Schnittke's music; the inclusion of symbolic images (a chair, a door, a bag) in the choreographic canvas; the appearance of other characters; the use of stage lighting to accentuate the transition from reality to the sphere of the subconscious; active choreographic development based on a technically saturated duet dance, replete with high supports in the neoclassical style, as well as acrobatic elements; semantic use of plastic quotations. It can be concluded that in order to develop the images and relationships of Anna Karenina and Alexey Vronsky, the choreographer chooses a duet as the dominant musical and choreographic form. Moreover, in his version of Anna Karenina, Neumeier makes three duets of the main characters a key component of the performance and the author's interpretation of the images of the main characters.

Electro-optic-modulator (EOM) based Mach-Zehnder (M-Z) interferometer is a novel method of controlling the carrier envelope offset frequency (f0). It is achieved by adjusting the envelop of the pulse, while keeping the carrier frequency unchanged. In this paper, the polarization control device involved in this method is simulated, and the influences caused by the deviation of the optical axis of the wave plate on the polarization direction and the degree of output laser are analyzed. An optical axis calibration method is proposed to reduce the influence caused by the deviation of optical axis of wave plate. The effects of pump current and EOM based M-Z interferometer on f0 and the beat note (fb) between the comb and the laser are compared with each other. The experimental results show that the effect of changing the pump current on fb is 7 MHz, when the f0 adjustment quantity is 9 MHz. Under the same f0 adjustment quantity, the influence of EOM based M-Z interferometer on fb is 0.2 MHz, which is only 1/35 of the influence of pump current. Therefore, it is verified that EOM based M-Z interferometer can effectively reduce the interference to fb. It provides a technical means to narrow the line width of optical comb by using fb to lock repetition rate (fr) .
