A THEORETICAL STUDY OF THE CRYSTAL STRUCTURES AND ELECTRONIC PROPERTIES OF BULK MoS2 AND ITS MONOLAYER BASED ON FIRST – PRINCIPLES CALCULATION
Authors: Doan Thi Kieu Anh , Tran Phan Thuy Linh , Luong Viet Mui
Published: February 2022

In this work, we have investigated the structural and electronic properties of both bulk and monolayer MoS2 based on the density functional theory (DFT) implemented in the CASTEP of Materials Studio package. The calculations are performed with the local density approximation (LDA) and generalized gradient approximation (GGA) functionals for crystal structure optimization and band structure of MoS2 bulk and monolayer. Our calculations show that the GGA functional calculated excellent band gap for bulk MoS2, while LDA functional is found to perform better for band gap calculations of a monolayer. The influence of composition in the energy bands has been realized by analyzing the partial density of states (PDOS) of each atom and density of states (DOS). By reducing the layer thickness from bulk to monolayer, it is found that band structure has the transitions from indirect band gap in the bulk MoS2 (1.53 eV) to direct band gap in the monolayer (1.82 eV). On the other hand, the charge density difference along z-direction shows that the major charge transfer occurs on the surface of the S atoms and there is a little accumulation around the surface of the Mo atoms. This property highlights the promising of MoS2 in improving the fabrication of optoelectronic devices in the future.

DESIGNING THE PROCEDURE FOR APPLYING THE LEARNING CORNERS METHODOLOGY TO ORGANIZE TEACHING WRITING SOCIAL ARGUMENTATIVE PARAGRAPHS FOR 11TH GRADERS
Authors: Phan Nguyen Tra Giang , Ha Thi Thanh Ngoan , Pham Thanh Linh , Nguyen Tuong Vi
Published: February 2022

Teaching writing social argumentative (SA) paragraphs is an important content in the Vietnamese Literature curriculum for High school, contributing to the formation and development of students' writing ability in school. However, the reality shows that teachers often organize writing lessons in just one pattern: all students will write on the same topic with the same system of ideas developed, and as a result, it is difficult to find the students' imprint in each writing. In this article, we propose to design the procedure of organizing teaching writing of SA paragraphs by Learning Corners - a methodology aimed at allowing students to acquire knowledge according to different learning styles, ensuring students' deep learning and comfortable learning - as a measure to overcome the above-stated situation as well as promote the positivity, initiative, and creativity of students when participating in the writing process.
TRAINING THE COMPETENCE OF APPLYING HISTORICAL KNOWLEDGE AND SKILLS FOR STUDENTS THROUGH USING ACTIVE TEACHING METHODS IN TEACHING HISTORY 11 AT TAM PHU HIGH SCHOOL, THU DUC CITY
Authors: Duong Thi Kim Oanh , Nguyen Thi Minh Tam
Published: February 2022

In the trend of innovating teaching methods in the direction of developing learners' competencies in high schools, active teaching encourages students to actively learn to form their own qualities, general and specific competencies. History 11 is a subject that provides students with general knowledge about Latter-day world History, Modern World History (1917 - 1945), Vietnam History (1858 - 1918). To help students form historical knowledge applying competence, teaching methods that stimulate students to learn actively are encouraged to be applied in teaching History 11 in high schools. However, the situation of teaching with one-way knowledge transfer, with little focus on training historical knowledge applying competence, still exists. Therefore, students are still passively absorbing one-way knowledge, memorizing facts, and their historical knowledge applying competence is still limited. The article analyzes fundamental theories of active teaching in History 11 and results of applying active learning methods in training the competence of applying historical knowledge and skills for students at Tam Phu high school, Thu Duc City.
APPLYING CORNER TEACHING METHOD AND SOME ACTIVE TEACHING TECHNIQUES IN TEACHING CHEMISTRY TO DEVELOP COOPERATIVE CAPABILITY FOR HIGH SCHOOL STUDENTS
Authors: Vu Thi Ngoc Oanh , Hoang Thu Ha , Nguyen Trung Thanh , Nguyen Mai Hoang , Vu Quoc Trung
Published: February 2022

One of the important competencies that need to be focused on when forming and developing for high school students, is cooperation capability. Students cooperate to solve problems in learning and life; build relationships, learn from each other, and help each other grow together. This article presents the application of the teaching method in the corner, the teaching technique of mind mapping, and the KWL technique to maximize the cooperation between students in the same group to solve the learning tasks in a corner. Instead of teachers using visual methods, experimental methods, and small group cooperation methods to guide students to acquire knowledge, in this experiment, teachers ask students in groups to cooperate with each other to self-determine goals, make plans, assign tasks, share ideas, listen to each other's ideas, and support each other to complete learning tasks in the corners. Teachers only observe students organize learning activities and provide support when needed. The results of applying these teaching techniques and this corner teaching method to the development of students' cooperative capability show that students' cooperative capability is developed through teaching Chemistry in high schools.

New math, a special phenomenon in the history of mathematics education
Authors: Tran Cuong
Published: February 2022

This article presents two theoretical research results regarding the “new math” movement, a special phenomenon in the history of mathematics education. Firstly, a brief history of that movement is clarified in a strictly logical manner: created by demands of the teaching of undergraduate mathematics degrees at university, the movement was activated by the special circumstances of the post-World War II period. Under the leadership of famous mathematicians, new math has changed the physiognomy of mathematics education at high schools since the 1960s. Despite receiving a lot of criticism and gradually entering a recession, the legacy of “new math” is undeniable. Furthermore, the systematization of certain lessons synthesized by researchers certainly preserves its full value for the reform of Vietnamese educational programs now in force.
Selection Advantage of Corporate Venture Capitalists and Its Welfare Effects
Authors: Hernández Juan
Published: February 2022

We develop a theoretical framework for corporate ventures where corporations' know-how gives them an advantage over regular financiers in identifying profitable projects. Corporations and venture capitalists compete to fund entrepreneurs in an environment featuring risk, adverse selection, and limited liability. The expected surplus of each project is independent of the financier and the efficient scale of each project differs among entrepreneurs. We characterize the optimal financial contracts arising in equilibrium and use this characterization to explore the effect corporations' knowledge has in this environment. We show that the presence of corporations in the financial market could be detrimental to welfare when corporations' selection advantage is small. When large, corporate venture capitalists' knowledge reduces the extensive margin inefficiency arising from adverse selection, meaning less socially inefficient projects are enacted. We also show that increasing the depth or breadth of corporations' knowledge leads to higher aggregate gains.
Women's view of the history of the Revolution (events in France at the end of the XVIII century in the works of M. Wollstonecraft, O. de Gouges, J. de Staёl)
Authors: Zvereva Maria
Published: February 2022

The article is devoted to highlighting the features and common characteristics of the English and French views of women on the Great French Revolution, based on the texts of M. Wollstonecraft, O. de Gouges and J. de Stael. The author analyzes the influence of the historical context on the formation of the writers' views on the events in France at the end of the XVIII century, as well as on the interpretation of the revolution itself, its causes and consequences in the works of M. Wollstonecraft, O. de Gouges and J. de Stael. The methodological basis of the research is the historical approach, the method of historical and philosophical reconstruction, comparative analysis, political and textual analysis and analysis of documents. In the future, the results can be used in studies of both the historiography of the French Revolution and its interpretations, as well as the history of the women's issue and the feminist movement.
The social and political ideal of Alexander Herzen and ideology of republicanism
Authors: Letnyakov Denis
Published: February 2022

The article offers a new look at the question of the ideological affiliation of Alexander Herzen. Usually the thinker is concidered to belong to either the revolutionary or the liberal tradition. In contrast, Herzen's legacy is viewed by the author in the context of the ideology of civil republicanism. The thesis that his political thought belongs to the left flank of republicanism is confirmed, in particular, by the fact that for Herzen the peasant community was not only the prototype of the future socialist system, but also a proto-civil institution of participation, which (in a transformed form) should form the basis of the political self-organization of the entire Russian society. In addition, Herzen's criticism of contemporary Europe is also partly carried out from a republican standpoint - he argues that the victorious "philistine spirit" in the West leads to depoliticization of society, degradation of the public sphere and to the unwillingness of Europeans to fight for true freedom and equality. Finally, in the mainstream of the republican tradition, Herzen criticizes the Russian autocracy as a tyrannical, arbitrary power, the subordination of which is incompatible with human dignity. According to the author, consideration of the ideas of Herzen, from a republican standpoint, allows us to take a fresh look at many plots of the intellectual history of Russia in the middle of the 19th century.
Understanding the sensitivity to the soil properties and rainfall conditions of two physically-based slope stability models
Authors: Marin Roberto J. , Mattos Álvaro J. , Fernández-Escobar Camilo J.
Published: February 2022

Physically-based models have been used to assess landslide susceptibility, hazard, and risk in many regions worldwide. They have also been regarded as valuable tools for landslide prediction and the development or improvement of landslide early warning systems. They are usually validated to demonstrate their predictive capacity, but they are not deeply studied regularly to understand the sensitivity of the input variables and the behavior of the models under many different rainfall scenarios. In this research paper, we studied two distributed physically-based models for shallow landslides: SLIP and Iverson. For this, the first-order second-moment (FOSM) method was used to calculate the contribution of random input variables (soil strength, unit weight, and permeability parameters) to the variance of the factor of safety. Different intensity and duration rainfall events were simulated to assess the response of the models to those rainfall conditions in terms of the factor of safety and failure probability. The results showed that the shear strength (cohesion and friction angle, in order of significance) parameters have the largest contribution to the variance in both models, but they vary depending on geological, geotechnical, and topographic conditions. The Iverson and SLIP models respond in different ways to the variation of rainfall conditions: for shorter durations (e.g. ≤ 8 h), increasing the intensity caused more unstable areas in the SLIP model, while for longer durations the unstable areas were considerably higher for the Iverson model. Understanding those behaviors can be useful for practical and appropriate implementation of the models in landslide assessment projects.
Wizualna Teoria Ugruntowana. Nauczanie teorii ugruntowanej przy pomocy obrazów i analizy wizualnej
Authors: Konecki Krzysztof T.
Published: February 2022

Artykuł powstał na podstawie mojego 20-letniego doświadczenia w nauczaniu metod jakościowych i teorii ugruntowanej. Chciałbym w nim pokazać użyteczność analizy wizualnej w nauczeniu metodologii teorii ugruntowanej i konstruowaniu kategorii i hipotez przy pomocy obrazów. Proces nauczania będzie pokazany na przykładzie realizowanego projektu badawczego dotyczącego bezdomności. Bardzo ważnym narzędziem jest sekwencjonowanie obrazów/zdjęć, które daje porównawczy wgląd w dane empiryczne i uczy metody porównawczej. Studenci mogą się nauczyć porównywać i odnajdywać wzory w empirycznych przykładach mających charakter wizualny. Niektóre z sekwencji pokazują fazy działań. W innych przypadkach kolejność zdjęć danych studentom nie jest dokładnie zaplanowana. Kolejność jest niemal przypadkowo (i sztucznie) stworzona, co zmusza studentów do znalezienia wzorów przy pomocy analizy porównawczej. Powinniśmy zawsze mieć świadomość tego co widzieliśmy przed obejrzeniem danej fotografii i co ewentualnie będziemy widzieć dalej – wszystko to ma wpływ na to co widzimy aktualnie. Przypomina to trochę analizę sekwencyjną danych tekstowych. W tego typu analizie zachęca się również studentów do nasycania kategorii przy pomocy danych pochodzących z obrazów. Dzięki temu nie tracą oni świadomości powiązań podczas przechodzenia od empirycznych przykładów do opracowanych koncepcyjnie własności kategorii i w końcu do ich definicji oraz tez teoretycznych. W ten sposób studenci uczą się również nasycania kategorii i ostatecznie uczą się jak budować teorię ugruntowaną przy pomocy obrazów, to jest uczą się generowania kategorii, własności i tez poprzez kodowanie i analizę teoretyczną obrazów.

Methodological Experiences in Collaborative Ethnography. Communication and Participation as Frameworks for Constructing in Common
Authors: Álvarez Veinguer Aurora , García Soto Rocío , Olmos Alcaraz Antonia
Published: February 2022

In this article, we will analyze how we built the research process of a collaborative ethnography with the Stop Evictions Granada 15M Movement (SEG15M). We will begin with a brief contextualization of the housing issues in Spain and the SEG15M movement to explain why we started the co-research experience with the movement. Next, we will clarify the composition, function, and main purposes of the ‘debate groups’ in our research, as well as their particular differences and dynamics concerning other qualitative techniques. Finally, we will focus on two main aspects, participation and communication, which emerged within the debates and later materialized into a transmedia project and the development of a radio soap opera. The latter is a product, and a process, of collaborative work that bridges communication and participation at the intra- and inter-group levels. It is a fictional story that emerges from the common lived experiences of the groups.
Child Disciplinary Practices versus Child Rights in Zimbabwe: Viewed through Social Work Lenses
Authors: Simango Tapiwa , Mafa Itai
Published: February 2022

Although parents are a vital cog in instilling and maintaining child discipline, very little information exists about the methods they employ. Using a qualitative approach, this paper explored the methods used by parents in Zimbabwe—an African context—to discipline children, elucidating their implications on children’s rights. The findings show that parents in Zimbabwe use both violent and non-violent disciplinary methods such as verbal reprimand, beating, and spanking, which, at times, violates children’s rights in the process. The use of non-violent means has also depicted a violation of children’s rights through deprivation of food, denial of playtime and shelter. Evident from the findings was, again, the existence of multiple-layered contestations on child discipline within the socio-cultural discourse—the most popularized being the debate on corporal punishment versus child rights violations. Through social work lenses, the paper provides a basis to dispel an anachronistic thought, which rationalizes the instrumentalization of punishment to achieve child discipline, underscoring the need for child rights-oriented discipline.

Published: February 2022

Transition to Parenthood is a two-session (antenatal and postnatal) module for inclusion in a birth and parenting education course, designed to proactively support perinatal and infant mental health. In this pilot study, 299 mothers and 241 fathers/partners participated in the whole module, with 35 mothers completing pre- and post-program measures of depression, anxiety, stress, and parenting confidence. Statistically significant improvements were found on all four measures with high effect sizes. Participant ratings of learning and satisfaction were high and persisted over time. These results provide support for the usefulness of group-based birth and parenting education that focuses on perinatal and infant mental health, with mental health peer workers co-delivering the program.

A política de internacionalização da educação em institutos politécnicos de Portugal e as parcerias com instituições brasileiras de educação profissional e tecnológica
Authors: Martins Tânia Barbosa , Batista Sueli Soares Santos
Published: February 2022

Ações e iniciativas portuguesas de internacionalização da educação se desenvolvem não somente com a União Europeia, mas também com países da África e América Latina. Os institutos politécnicos portugueses são importantes parceiros das instituições públicas brasileiras de educação profissional e tecnológica, celebrando acordos interinstitucionais voltados para o ensino, a pesquisa e a extensão. O objetivo desse artigo é compreender as estratégias e os alcances das parcerias entre o Instituto Político de Coimbra e o Instituto Politécnico do Porto face às três instituições públicas de educação profissional e tecnológica brasileiras: Instituto Federal de Educação, Ciência e Tecnologia do Sul de Minas Gerais - IFSULDEMINAS e de São Paulo - IFSP e o Centro Estadual de Educação Tecnológica Paula Souza – CEETESP, buscando conhecer as concepções e práticas de educação profissional e tecnológica no âmbito da internacionalização da educação. Por meio de uma abordagem qualitativa a partir do levantamento de documentos oficiais, da produção acadêmica e de entrevistas com gestores foi possível concluir que tais parcerias decorrem de questões geopolíticas, demográficas e da reformulação no sistema educacional português em conformidade com as diretrizes da União Europeia. Enfatiza-se a relevância da experiência portuguesa de formação profissional e tecnológica que faz com que as instituições congêneres brasileiras tenham mais facilidade e mesmo interesse em desenvolver parcerias que precisam ser ampliadas como oportunidades efetivas de construção de projetos formativos de internacionalização da educação.
Epispadias: recent techniques
Authors: Bizic Marta R. , Stojanovic Borko , Bencic Marko , Joksic Ivana , Djordjevic Miroslav L.
Published: February 2022

Aim: This paper presents the latest surgical approaches for epispadias treatment in the pediatric population, as well as those for adolescent and adult populations after initial failed repair in childhood. Methods: The retrospective study was conducted between March 2005 and May 2020 and included 18 patients with the mean age of 21 months (range 11-48 months) (Group A), who underwent primary epispadias repair and 15 patients with the mean age of 18 years (range 13-29 years) (Group B), who underwent redo surgery after failed epispadias repair in childhood. In Group A, the surgery was performed as a one-stage procedure using complete penile disassembly technique, while, in Group B, the surgery was done as a two-stage procedure and included complete straightening and lengthening of the penis, followed by urethral reconstruction. Penile straightening and lengthening were achieved by tunica albuginea incision and grafting. In Group A, the urethral plate was mobilized, transposed ventrally, and tubularized and augmented with vascularized preputial skin flap where needed. In Group B, the urethra was reconstructed either using the buccal mucosa graft and genital skin flaps or with tubularization of genital skin flaps. Successful treatment was defined as a functional and esthetically acceptable penis without complications. Results: The mean follow-up was 88 months (range 15-197 months). Satisfactory results were achieved in 26/33 patients. Urethral fistula occurred in 4/18 patients from Group A and in 3/15 patients in Group B and was surgically repaired after four months. Skin dehiscence occurred in eight patients, five from Group A and three from Group B. Recurrent penile curvature was observed in 2/18 patients from Group A and required surgical correction and in 2/15 patients from Group B and was mild and did not need surgical repair. Eleven patients from Group B who filled out the International Index for Erectile Function reported satisfying erectile function, sexual desire, intercourse, and overall satisfaction. Conclusion: Primary or redo epispadias repair is challenging even for experienced reconstructive urologists. Only radical surgical approach can lead to complete correction of all deformities and provide successful outcome.

Published: February 2022

Aim: To investigate the changes of insulin resistance (IR), parameters of arterial stiffness, concentrations of N-terminal pro-brain natriuretic peptide (NT-proBNP), and echocardiographic parameters in patients with cardiac autonomic neuropathy (CAN) and type 2 diabetes mellitus (T2D). Methods: This study recruited 44 patients with T2D (19 patients without CAN and 25 patients with CAN) and 15 healthy volunteers. Arterial stiffness, immunoreactive insulin, homeostasis model assessment IR, NT-proBNP parameters, and echocardiographic examination were assessed. Results: Development of CAN is associated with increase in NT-proBNP levels, IR parameters, and arterial stiffening. Among patients with CAN, arterial stiffness parameters were considered as high. We found out that among patients of this group, the value of brachial augmentation index was normal in 52%, elevated in 40%, and pathological in 8%; pulse wave velocity was normal in 16%, elevated in 52%, and pathological in 32% of cases. Obtained results showed that development of CAN is accompanied by more pronounced left ventricular diastolic dysfunction and by formation of left ventricular hypertrophy (LVH), mostly by concentric type. Among patients of this group concentric LVH was diagnosed among 76 % and eccentric LVH among 16% of persons. Multiple regression analysis, after controlling for age, sex, diabetes duration, blood pressure, HbA1c, and left ventricular mass index, showed an independent association of heart rate response to deep breathing with pulse wave velocity (P < 0.001). Conclusion: Development of CAN is associated with increased IR parameters, increased levels of NT-proBNP, arterial stiffening, left ventricular diastolic dysfunction, and formation of LVH, mostly by concentric type.
ESD for duodenal carcinoma
Authors: Kato Motohiko , Sasaki Motoki , Maehata Tadateru , Yahagi Naohisa
Published: February 2022

Superficial non-ampullary duodenal epithelial tumors (SNADETs) are rare, but their incidence is increasing recently. Considering the invasiveness of pancreatoduodenectomy, endoscopic treatment is widely accepted as an option for maintaining patients’ quality of life. SNADETs larger than 20 mm are an indication for duodenal ESD, and intramucosal cancer can be cured by ESD. Duodenal ESD is extremely difficult with a high risk of adverse events. However, some modified treatment techniques such as the water pressure method or the pocket creation method have been proposed to improve outcomes. Furthermore, evidence is accumulating that protection of the mucosal defect reduces delayed adverse events after duodenal endoscopic treatments. Moreover, endoscopic drainage of the bile and pancreatic juice is effective as conservative management even in cases with delayed perforation.
Biological evidence of cancer stem-like cells and recurrent disease in osteosarcoma
Authors: Jubelin Camille , Muñoz-Garcia Javier , Cochonneau Denis , Moranton Emilie , Heymann Marie-Françoise , Heymann Dominique
Published: February 2022

Sarcomas are a large family of cancers originating in the mesenchyme. Composed of more than 100 histological subtypes, soft tissue and bone sarcomas remain clinically challenging, particularly in children and adolescents in whom sarcomas are the second most common malignant entities. Osteosarcoma is the main primary bone tumor in adolescents and young adults and is characterized by a high propensity to induce distant metastatic foci and become multi-drug resistant. The innate and acquired resistance of osteosarcoma can be explained by high histological heterogeneity and genetic/molecular diversity. In the last decade, the notion of cancer stem-like cells (CSCs) has emerged. This subset of cancer cells has been linked to drug resistance properties, recurrence of the disease, and therapeutic failure. Although CSCs remain controversial, many elements are in favor of them playing a role in the development of the drug resistance profile. The present review gives a brief overview of the most recent biological evidence of the presence of CSCs in osteosarcomas and their role in the drug resistance profile of these rare oncological entities. Their use as promising therapeutic targets is discussed.

Aim: Most of the carcinogenic pollutants coming from tobacco smoking or other combustion processes tend to accumulate in settled house dust (SHD) over time. This study evaluated the load of these pollutants in smokers and non-smokers’ houses from relatively fresh SHD collected in five different districts on the island of Malta. Methods: An improved, efficient extraction method to obtain three fractions from a 200 mg of SHD was developed. It was validated for the analysis of nicotine and polycyclic aromatic hydrocarbons (PAH) by GC-MS/MS and nicotelline and TSNA by LC-MS/MS. Kruskal-Wallis H tests were used to evaluate differences across districts, while a Mann-Whitney U test was used to check differences between smokers and non-smokers’ houses. Diagnostic ratios were used to evaluate the carcinogenicity of PAH in SHD in Malta. Results: For all analytes, no statistical difference was observed across different districts, but, in smokers’ houses, 97.9% of the total concentration of all target analytes found in SHD is nicotine, 0.1% is TSNA, and 2.0% is PAH. In non-smokers’ houses, nicotine represents 16.8% of the load, while 0.4% and 82.8% are TSNA and PAH, respectively. The carcinogenicity of the PAH mixture in Maltese SHD, expressed as the mean benzo(a)pyrene equivalent (BaPeq) is 371 ng/g. Conclusion: Indoor activities, ventilation practices, and infiltration of outdoor pollutants contribute to a complex SHD composition. Although the BaPeq is on the lower end of carcinogenicity, the effects of a mixture including tobacco-related potent carcinogens in SHD are largely unknown. In view of indoor, continuous exposure to SHD through several pathways, further research is warranted.
The Riemann Hypothesis Is True If The Zeros Of $\xi(s)$ Have Strict Increasing Imaginary Parts
Authors: Zhang Weicun
Published: February 2022

Based on Hadamard product, a new expression of the completed zeta function $\xi(s)$ is obtained, i.e., $$\xi(s)=\xi(0)\prod_{i=1}^{\infty}\Big{(}\frac{\beta_i^2}{\alpha_i^2+\beta_i^2}+\frac{(s-\alpha_i)^2}{\alpha_i^2+\beta_i^2}\Big{)}^{d_i}$$ where $\rho_i=\alpha_i+j\beta_i, \bar{\rho}_i=\alpha_i-j\beta_i$ are complex conjugate zeros of $\xi(s)$, $d_i\geq 1$ (natural numbers) are the multiplicities of $\rho_i$, $0<\alpha_i<1, \beta_i\neq 0, i\in \mathbb{N}$ are natural numbers from 1 to infinity. Suppose $\beta_i$ are in order of strict increasing $|\beta_i|$, i.e., $|\beta_1|<|\beta_2|<|\beta_3|<, \cdots$, or in another word, for each $\beta_i$, there are only four (two pairs) possible zeros (regardless of their multiplicities), i.e., $\alpha_i \pm j\beta_i, 1-\alpha_i \pm j\beta_i$. According to the functional equation $\xi(s)=\xi(1-s)$, We have $$\xi(0)\prod_{i=1}^{\infty}\Big{(}\frac{\beta_i^2}{\alpha_i^2+\beta_i^2}+\frac{(s-\alpha_i)^2}{\alpha_i^2+\beta_i^2}\Big{)}^{d_i} =\xi(0)\prod_{i=1}^{\infty}\Big{(}\frac{\beta_i^2}{\alpha_i^2+\beta_i^2}+\frac{(1-s-\alpha_i)^2}{\alpha_i^2+\beta_i^2}\Big{)}^{d_i}$$ i.e., $$\prod_{i=1}^{\infty}\Big{(}1+\frac{(s-\alpha_i)^2}{\beta_i^2}\Big{)}^{d_i}=\prod_{i=1}^{\infty}\Big{(}1+\frac{(1-s-\alpha_i)^2}{\beta_i^2}\Big{)}^{d_i}$$ which, by Lemma 3, is equivalent to $$\alpha_i= \frac{1}{2}, i\in \mathbb{N}, \text{ from 1 to infinity.}$$ Thus, the Riemann Hypothesis is true if we have $|\beta_1|<|\beta_2|<|\beta_3|<, \cdots$.
Russian and International Data Sources: Integration of Data on Russian Research Organizations
Authors: Apanovich Zinaida Vladimirovna
Published: February 2022

This paper considers international and Russian-language data sources providing information about Russian research-related organizations. Information about research organizations is an important attribute that enables one to identify the authors of scientific publications, as well as to analyze the geographical distribution of publications and to assess the impact on the citation of the publications associated with geographic factors. However, information about national research organizations, for example, information about Russian research organizations, is often incomplete or distorted in international databases. Data sources such as GRID, Russian and English chapters of Wikipedia, Wikidata and eLIBRARY.ru are considered. It is demonstrated that Russian-language data sources contain more information about Russian research-related organizations than most international data sources, but this information is not available in English-language data sources. To solve this problem, a method for integrating information from multilingual data sources has been developed. Experiments on the comparison and integration of information about Russian research organizations in international and Russian data sources are outlined. An experimental version of the database of scientific organizations comprising 3143 scientific organizations has been created. The work is an intermediate step towards the creation of an open and extensible knowledge graph.

Published: February 2022

The role of the Common Digital Space of Scientific Knowledge (CDSSK) in the development of educational technologies is considered. CDSSK is being implemented by a number of Russian organizations as a digital environment of a new generation for the purpose of providing information for scientific research, education, popularization of science and preservation of scientific heritage. The CDSSK structure provides for the formation and support of special components related to secondary and higher education. One of the elements related to education in the structure of the CDSSK is a scientific virtual exhibition. Such an exhibition can be dedicated both to a specific person and a scientific event in general. Virtual exhibitions combine a variety of resources related to the presented topic (biographies of scientists, related museum and archival materials, copies of films, interactive multimedia resources). The paper presents the basic principles of constructing the CDSSK educational component, provides examples of implemented virtual exhibitions used in the educational process. Virtual exhibitions are implemented on the digital library “Scientific Heritage of Russia” platform.
Long-term Electronic Archives: Modernization and Integration

Electronic archives are more than just “paper based” funds transferred into digital form. The task of forming a qualitative source base for historical research is solved in these projects on the basis of interdisciplinary interaction of computer science and humanities. One of the longterm projects at the IIS SB RAS is a creation of a methodology and technologies for the formation, use and support of electronic archives. Here are information systems of historical orientation that were created on the basis of the solutions described in this paper: the Electronic Archive of Academician A.P. Ershov, Photo Archive of the Siberian Branch of the Russian Academy of Sciences, Archive of the newspaper “Science in Siberia”, Open Archive of SB RAS, etc. Each of these resources has its own specifics, but in general, their documentary and information fund is based on the general social and territorial basis of scientific and social activities of the Siberian Branch of Academy of Sciences of the USSR/RAS and Novosibirsk Akademgorodok. In this report we will look into the general problems of creating electronic archives, relevant technologies, and architectural solutions. Some approaches to the integration/disintegration of isolated electronic resources are given on the examples of our electronic archives and on the basis of generally accepted and created tools. We will also examine the experience of using proprietary and open source software, their advantages and weaknesses.
On some journal citation properties: Math-Net.Ru as a case

This paper presents a study of bibliographical references cited in articles published by MathNet.Ru journals. Based on data obtained from mathematical portal Math-Net.Ru, we built a journals citation graph, with its vertices denoting journals, and edges representing bibliographical references (citations) between papers published in these journals. To increase the reliability of the constructed graph, we chose a 2010-2021 citation time interval, when distribution of citing papers (papers that have cited other works) had stabilized at 3500-4500 citations per year. The structure of citation ageing is investigated; it is shown that the half-life of these citations is 8 years. So, the publication date of cited papers (papers that have been cited by other works) was limited to the year 2002. The constructed citation graph was found to have a small diameter and high density, indicating that there is a high level of research collaboration in Math-Net.Ru. It is shown that there is no Matthew effect as a pronounced advantage in the citations of leading journals in relation to less well-known ones. The adequacy of the Math-Net.Ru journal citation graph as a scientific collaboration model is confirmed by comparing the ranking of journals included the citation graph with their Science Index ranking in scientific electronic library eLIBRARY.RU. The two rankings were found to have a direct moderate relationship between themselves. A number of substantive conclusions are drawn from analysis of the citation graph.
