Spontaneous and Controlled Macroscopic Chiral Symmetry Breaking by Means of Crystallization
Authors: Coquerel Gérard , Hoquante Marine
Published: October 2020

In this paper, macroscopic chiral symmetry breaking refers to as the process in which a mixture of enantiomers departs from 50–50 symmetry to favor one chirality, resulting in either a scalemic mixture or a pure enantiomer. In this domain, crystallization offers various possibilities, from the classical Viedma ripening or Temperature Cycle-Induced Deracemization to the famous Kondepudi experiment and then to so-called Preferential Enrichment. These processes, together with some variants, will be depicted in terms of thermodynamic pathways, departure from equilibrium and operating conditions. Influential parameters on the final state will be reviewed as well as the impact of kinetics of the R ⇔ S equilibrium in solution on chiral symmetry breaking. How one can control the outcome of symmetry breaking is examined. Several open questions are detailed and different interpretations are discussed.

The way a database schema is designed has a high impact on its performance in relational databases, which are symmetric in nature. While the problem of schema optimization is even more significant for NoSQL (“Not only SQL”) databases, existing modeling tools for relational databases are inadequate for this asymmetric setting. As a result, NoSQL modelers rely on rules of thumb to model schemas that require a high level of competence. Several studies have been conducted to address this problem; however, they are either proprietary, symmetrical, relationally dependent or post-design assessment tools. In this study, a Dynamic Schema Proposition (DSP) model for NoSQL databases is proposed to handle the asymmetric nature of today’s data. This model aims to facilitate database design and improve its performance in relation to data availability. To achieve this, data modeling styles were aggregated and classified. Existing cardinality notations were empirically extended using synthetically generated queries. A binary integer formulation was used to guide the mapping of asymmetric entities from the application’s conceptual data model to a database schema. An experiment was conducted to evaluate the impact of the DSP model on NoSQL schema production and its performance. A profound improvement was observed in read/write query performance and schema production complexities. In this regard, DSP has significant potential to produce schemas that are capable of handling big data efficiently.

Published: October 2020

Filifactor alocis is a Gram-positive asaccharolytic, obligate anaerobic rod of the phylum Firmicutes, and is considered an emerging pathogen in various oral infections, including periodontitis. We here aimed to perform phylogenetic analysis of a genome-sequenced F. alocis type strain (ATCC 35896; CCUG 47790), as well as nine clinical oral strains that we have independently isolated and sequenced, for identification and deeper characterization of novel genomic elements of virulence in this species. We identified that 60% of the strains carried a gene encoding a hitherto unrecognized member of the large repeats-in-toxins (RTX) family, which we have designated as FtxA. The clinical infection origin of the ftxA-positive isolates largely varied. However, according to MLST, a clear monophylogeny was reveled for all ftxA-positive strains, along with a high co-occurrence of lactate dehydrogenase (ldh)-positivity. Cloning and expression of ftxA in E. coli, and purification of soluble FtxA yielded a protein of the predicted molecular size of approximately 250 kDa. Additional functional and proteomics analyses using both the recombinant protein and the ftxA-positive, and -negative isolates may reveal a possible role and mechanism(s) of FtxA in the virulence properties of F.alocis, and whether the gene might be a candidate diagnostic marker for more virulent strains.
Exploring the Dominant Runoff Processes in Two Typical Basins of the Yellow River, China
Authors: Ran Guang , Jian Shengqi , Wu Qiang , Zhang Li , Hu Caihong
Published: October 2020

Storm runoff in basins is comprised of various runoff processes with widely disparate infiltration and storage capacities, such as Hortonian overland flow (HOF), saturated overland flow (SOF), sub-surface flow (SSF), and deep percolation (DP). Areas may be classified according to these various runoff processes based on the soil characteristics, geology, topography, and land-use. This study analyzes changes in runoff components in the Jialu River basin and the Fen River (Jingle sub-basin) during runoff generation from 1980 to 2013 using the runoff segmentation method. Based on the decision scheme, the dominant runoff process (DRP) in the basins was distinguished using geographic information system (GIS) tools. The impact of different runoff process distributions on the changes in the runoff for the basin was determined. The results show that the floods in the Jialu River basin and Jingle sub-basin were dominated by overland flow components. Compared with 1980–1999, the proportion of overland flow components for 2000–2013 in two basins showed a decreasing trend by 8.3% and 7.1%, respectively, while the interflow and underground runoff components increased. In addition, HOF was the DRP in the Jialu River basin and Jingle sub-basin from 2000 to 2013. The area of the rapid runoff processes (HOF, SOF1, and SSF1) in the Jialu River basin and Jingle sub-basin accounted for 89% and 78% of the entire basin, respectively. In contrast, the slow runoff processes (SOF2, SSF2, and DP) accounted for 11% and 22% of the entire basin, respectively. The runoff of the Jingle sub-basin was substantially lower than that of the Jialu River basin under the same rainfall conditions, because of the influence of the distribution of different runoff processes. Compared with the Jialu River Basin, the peak discharge and runoff of Jingle sub-basin were 190.4 m3/s and 2.85 mm lower on average, respectively. The results of this study provide useful information to understand land-use changes and formulate management practices to reduce flooding in the Yellow River.
Application of Multi-Source Data Fusion Method in Updating Topography and Estimating Sedimentation of the Reservoir
Authors: Liu Yu , Xu Shiguo , Zhu Tongxin , Wang Tianxiang
Published: October 2020

The underwater terrain of a reservoir can experience significant changes due to the effects of erosion and siltation during decades of operation. Therefore, existing topographic data no longer reflect current reservoir terrains and need to be updated. In this paper, we propose a fast and economical method for updating the topography of a reservoir. According to multi-source data fusion, we effectively integrated sonar sounding data, cartographic data, and manual measurement data to update and reconstruct the bottom topography of a reservoir in Northeast China. By comparing the updated topography with the measured elevation, the average error of the simulation results is only 0.56%, which shows that the updated topography can accurately reflect the actual topography of the reservoir. Furthermore, by using the surface volume tool in ArcGIS, we developed the original and updated the elevation and volume curves of the reservoir. Finally, the amount of silting and its distribution in the reservoir were obtained by calculating the difference between the original and updated elevation and volume curves. The results show that the total sedimentation volume in the researching reservoir is about 4.3 million m3, which is mainly concentrated in the areas with an elevation below 50 m and above 60 m.

Published: October 2020

The novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes coronavirus disease 2019 (COVID-19) and has created a worldwide pandemic. Many patients with this infection have an asymptomatic or mild illness, but a small percentage of patients require hospitalization and intensive care. Patients with respiratory tract involvement have a spectrum of presentations that range from scattered ground-glass infiltrates to diffuse infiltrates with consolidation. Patients with the latter radiographic presentation have severe hypoxemia and usually require mechanical ventilation. In addition, some patients develop multiorgan failure, deep venous thrombi with pulmonary emboli, and cytokine storm syndrome. The respiratory management of these patients should focus on using low tidal volume ventilation with low intrathoracic pressures. Some patients have significant recruitable lung and may benefit from higher positive end-expiratory pressure (PEEP) levels and/or prone positioning. There is no well-established anti-viral treatment for this infection; the United States Food and Drug Administration (FDA) has provided emergency use authorization for convalescent plasma and remdesivir for the treatment of patients with COVID-19. In addition, randomized trials have demonstrated that dexamethasone improves outcomes in patients on mechanical ventilators or on oxygen. There are ongoing trials of other drugs which have the potential to moderate the acute inflammatory state seen in some of these patients. These patients often need prolonged high-level intensive care. Hospitals are confronted with significant challenges in patient management, supply management, health care worker safety, and health care worker burnout.

¿Es necesario el amparo electoral para proteger derechos políticos en procesos electorales?
Authors: Díaz Zegarra Walter A.
Published: October 2020

La justicia constitucional peruana ha establecido que las resoluciones del Jurado Nacional de Elecciones pueden ser revisadas cuando afectan derechos fundamentales; siendo que el mecanismo adecuado es el proceso de amparo; sin embargo, su uso no ha significado eficacia, toda vez que son pocos los casos en que ha reparado el derecho conculcado y la mayoría de las veces termina solo determinando responsabilidad de las autoridades que vulneran estos derechos; de ahí la necesidad de evaluar la posibilidad de establecer un amparo electoral con trámite e instancias diferentes al amparo clásico.

Published: October 2020

The results of experimental modeling of impact transformation of weakly ordered carbon substance by short-pulse laser radiation on glassy carbon are presented. The experiments yielded extremely high temperatures of ~14500 K and pressures of ~300 GPa, which are comparable with temperatures and pressure of the formation of large Earth’s meteorite craters. The analysis of the transformation products of a target substance showed melting of glassy carbon, its further solidifcation, partial crystallization upon cooling and formation of polyphase composites, which contain hexagonal nanocrystalline graphite and hollow onion-like and one- and two-layer fullerene-like structures. The synthetic products, including high-pressure carbon polymers and hollow onionlike multi-layer fullerene-like structures are of interest as carbon materials, which form at ultrahigh pressures and temperatures. The results of experimental modeling can also be used for the comparison with natural products to explain the formation of natural high-pressure carbon composites after non-graphite precursor.

Authors: Antonova N.L. , Lozovskaya K.B.
Published: October 2020

On the basis of materials of a sociological study, the authors consider international scholarship programs as a tool for academic mobility. Students’ academic mobility is a factor and condition for the internationalization of higher education and the development of modern universities. Based on a questionnaire survey of undergraduate students (n=250), interviews with postgraduates (master degree) (n=12), as well as interviews with MOFCOM Scholarship program fellows (n=3), the article states that students are ready to join international academic mobility programs and compete for international scholarships to study primarily in European countries, the USA, and China. At the same time, students are interested in scholarships implemented at the state level and at the level of specific universities. A factor for choosing a scholarship program is, first of all, the scholarship amount which should cover, along with tuition, transport costs, accommodation, food, and cultural activities. Studying in a foreign university allows students to improve their foreign language and serves as a factor in strengthening their position of a future specialist in the labour market.

Authors: Obukhov K.N.
Published: October 2020

The article examines the main modern preconditions for the study of volunteering in Russia and Udmurtia. The materials of an online survey among volunteers show the main socio-demographic profiles of participants in the volunteer movement, their values and attitudes, as well as priority areas for the development of volunteer activities and the main problems that volunteers face. The problems of the close relationship of the volunteer movement with formal state and near-state structures, the internal heterogeneity of the volunteer movement, the presence of models of segregation and discrimination within the volunteer movement are identified. It is stated that all the identified problems impede the development of the volunteer movement as an element of civil society self-organization. A comparison is made between the differences in value orientations of young people living in Udmurtia and young people involved in volunteer movement. The article shows that volunteers share a distinct set of values and are more socially oriented. In addition, it shows the high importance of friendship and close ties in the volunteer environment, which under favorable conditions associated with taking into account the opinion on promising areas of work, can be a driver of the volunteer movement in Udmurtia.

Why do some TED Talks get more views, go viral? What makes a TED talk the change maker in outlook, attitude and behaviour? What intrigues and influences people? This paper aims to analyze the various drivers behind maximum view count of certain TED talks from the start of 2006 till the end of June 2020. The analysis takes into consideration various parameters such as the speaker’s profession, chosen topic, his/her transcript, number of views, comments, tags to name a few. This analysis will help an aspiring TED Talker identify the drivers and plan a video that will attract more view counts. This research paper uses Exploratory Data Analysis with a special emphasis on Natural Language Processing using the native Latent Dirichlet Allocation model from Gensim and the LDA Mallet. Analysis of the TED Talk data suggests that the content is a prime driving factor rather than the public speaking abilities thereby making the view count less predictable.

Abstract

The ceaseless connectivity imposed by the internet has
made many vulnerable to offensive comments, be it their
physical appearance, political beliefs, or religion. Some define
hate speech as any kind of personal attack on one’s identity or
beliefs. Of the many sites that grant the ability to spread such
offensive speech, Twitter has arguably become the primary
medium for individuals and groups to spread these hurtful
comments. Such comments typically fail to be detected by
Twitter’s anti-hate system and can linger online for hours
before finally being taken down. Through sentiment analysis,
this algorithm is able to distinguish hate speech effectively
through the classification of sentiment.

Published: October 2020

An AC-AC converter with high-frequency link employing LLC resonant converter operating in the vicinity of the resonance frequency is studied, in which the output stage is unique and formed by a high-frequency AC-AC converter employing four quadrant switches. The topology, its operation and the modulation strategy are presented. The high-frequency stage switches located on the primary side of the transformer operate with soft switching of the ZVS type, while the four quadrant switches that form the output stage operate with soft switching of the ZCS type. Experimental data on a 1.5 kW experimental prototype that was designed, built and tested in the laboratory, with 220 VRMS input, 220 VRMS output and 40 kHz switching frequency are given in the paper. The studied converter can be considered a candidate for the building block of medium voltage solid-state transformers (SST) for power distribution systems.

Authors: Niture Nandkumar
Published: October 2020

The AI, deep learning and machine learning algorithms are gaining the ground in every application domain of information technology including information security. In formation security domain knows for traditional password management systems, auto-provisioning systems and user information management systems. There is another raising concern on the application and system level security with ransomware. On the existing systems cyber-attacks of Ransomware asking for ransom increasing every day. Ransomware is the class of malware where the goal is to gain the data through encryption mechanism and render back with the ransom. The ransomware attacks are mainly on the vulnerable systems which are exposed to the network with weak security measures. With the help of machine learning algorithms, the pattern of the attacks can be analyzed. Create or discuss a workaround solution of a machine learning model with combination of cryptographic algorithm which will enhance the effectiveness of the system response to the possible attacks. The other part of the problem, which is hard part to create an intelligence for the organizations for preventing the ransomware attacks with the help of intelligent system password management and intelligent account provisioning. In this paper I elaborate on the machine learning algorithms analysis for the intelligent ransomware detection problem, later part of this paper would be design of the algorithm.

Subjectivity Reducing In Software Version Criticity Classification With The Support Of An Expert System
Authors: Gatto Dacyr , Sassi Renato José
Published: October 2020

In the
software version release management process, there is a need, on the part of
human specialists, to classify the criticality of each software version However,
the subjectivity of this classification may be present according to the
experience acquired by specialists over the years. In order to reduce
subjectivity in the process, an Artificial Intelligence technique called the
Expert System (ES) can be applied to represent the knowledge of human
specialists and use it in problem solving. Thus, the aim
of this paper was to reduce the subjectivity in the criticality classification
of the software version with the support of the Expert System. To this end,
a questionnaire was developed with the objective of obtaining the criticality
opinions classified as High, Medium and Low in each specialist's software
version to assist in the preparation of the ES production rules. ES generated 17 production rules with a 100%
confidence level applied to a production database. The results of the classification carried out by the ES corresponded
to the classification carried out by the specialists in the production base,
that is, the ES was able to represent their knowledge. Then, another questionnaire was applied to
the specialists in order to verify the perception of satisfaction regarding the
use of the ES with a result obtained of 4.8, considered satisfactory. It
was concluded, then, that the ES supported the reduction of subjectivity in the
classification of the criticality of software version.
Kajian Praktik Penjaminan Mutu Terhadap Pemenuhan Standar Nasional Pendidikan Di Universitas Ichsan Gorontalo

Perguruan Tinggi Swasta (PTS) di lingkungan Lembaga Layanan Pendidikan Tinggi (LLDIKTI) Wilayah IX Sulawesi, dimana Tahun 2019 sebanyak 11 PTS yang dicabut izinnya karena tidak mampu melakukan aktivitas akademik sesuai dengan Standar Nasional Pendidikan Tinggi. Universitas Ichsan Gorontalo khususnya sebagai perguruan tinggi swasta di bawah naungan LLDKTI wilayah IX Sulawesi juga mendapatkan sanksi administrasi, hal ini dikarenakan dari hasil pemeriksaan Tim Evaluasi Kinerja Akademik (EKA) Kemenristek Dikti ditemukannya pelaksanaan kegiatan akademik tidak sesuai dengan Standar Nasional Pendidikan Tinggi dan Peraturan perundang-undangan yang berlaku. Oleh karenanya penting mengkaji lebih dalam praktik penjaminan mutu di Universitas Ichsan Gorontalo dalam pemenuhan Standar Nasional Pendidikan Tinggi. Hasil penelitian menunjukkan bahwa Universitas Ichsan Gorontalo telah memenuhi Standar Nasional Pendidikan Tinggi yang dapat dilihat dari ketersediaan dokumen standar. Akan tetapi, masih terbatasnya penunjang pelaksanaan penjaminan mutu di Universitas Ichsan Gorontalo dari aspek sumber daya manusia dan pendanaan. Proses penetapan standar pada Universitas Ichsan Gorontalo belum melibatkan pihak eksternal dalam hal ini stakeholder yang berimplikasi pada pelaskanaannya yang tidak konsisten dalam memenuhi isi standar yang telah ditetapkan. Selain itu, monitoring dan evaluasi yang minim membuat pelaksanaan standar tidak berjalan sebagaimana yang diharapkan

Dois casos clínicos são apresentados para explorar as diferenças técnicas e discutir as vantagens e desvantagens do uso de zircônia folheada ou monolítica para confeccionar coroas únicas posteriores. O primeiro caso descreve as etapas clínicas na fabricação de uma coroa monolítica em um segundo pré-molar inferior esquerdo usando zircônia de alta translucidez. Mostra a utilização de um preparo dentário conservador baseado nas propriedades mecânicas superiores que este material apresenta, bem como nas características ópticas finais alcançadas pelo sombreamento e coloração. No segundo caso, foi realizado um tratamento restaurador convencional em bicamada com estrutura de zircônia seguida de estratificação com cerâmica de feldspato no primeiro molar inferior esquerdo. A literatura recente indica que cada uma dessas alternativas restauradoras apresenta vantagens e desvantagens específicas. Fatores como desempenho mecânico, fratura, características estéticas, sucesso clínico, taxas de complicações, desempenho de adesão e desgaste do antagonista são discutidos comparando os dois conjuntos restauradores. Os dados destacam que as coroas monolíticas evitam um grande problema relatado nas restaurações de duas camadas: o lascamento da cerâmica de recobrimento. As coroas monolíticas também permitem preparações dentárias minimamente invasivas, aumentando assim a preservação do remanescente dentário. No entanto, faltam dados que sustentem a similaridade do desempenho estético entre as montagens monolítica e bicamada, sendo a previsibilidade de uso restrita para a região posterior, pois casos que demandam alto apelo estético continuam a utilizar fundamentalmente as restaurações bicamada. Não foram encontradas falhas, e a satisfação do paciente foi relatada em ambas as técnicas após o acompanhamento de 12 meses.
