Computing Graph Neural Networks: A Survey from Algorithms to Accelerators

Graph Neural Networks (GNNs) have exploded onto the machine learning scene in recent years owing to their capability to model and learn from graph-structured data. Such an ability has strong implications in a wide variety of fields whose data are inherently relational, for which conventional neural networks do not perform well. Indeed, as recent reviews can attest, research in the area of GNNs has grown rapidly and has lead to the development of a variety of GNN algorithm variants as well as to the exploration of ground-breaking applications in chemistry, neurology, electronics, or communication networks, among others. At the current stage research, however, the efficient processing of GNNs is still an open challenge for several reasons. Besides of their novelty, GNNs are hard to compute due to their dependence on the input graph, their combination of dense and very sparse operations, or the need to scale to huge graphs in some applications. In this context, this article aims to make two main contributions. On the one hand, a review of the field of GNNs is presented from the perspective of computing. This includes a brief tutorial on the GNN fundamentals, an overview of the evolution of the field in the last decade, and a summary of operations carried out in the multiple phases of different GNN algorithm variants. On the other hand, an in-depth analysis of current software and hardware acceleration schemes is provided, from which a hardware-software, graph-aware, and communication-centric vision for GNN accelerators is distilled.

Current stage of higher education internationalization: new characteristics, world leaders and challenges for Russia

At its present stage of internationalization of education, its architecture and forms have changed. The study of these aspects requires an integrated approach. Increasing the volume of exports of educational services remains a priority for Russia, which, according to the authors, does not realize its educational export potential sufficiently. The purpose of the article is to reveal the features of the current stage of internationalization of higher education through the compilation of its complex characteristics by a set of cross-sections, to interpret the calculations obtained in a new way, to identify new facts and factors affecting the development trend and to develop proposals for Russia as an exporter of educational services. The main sources used were the statistical databases of the WTO, the EEC of the EAEU. Analytical approach, comparative and statistical analysis were used. As a result, the authors found confirmation of the continuing trend of growth in global spending on education, the volume of investments in the global market of educational services, an increase in the number of foreign students, and the preservation of Russia's share in the number of foreign students. The authors also identified new characteristics of the global educational services market, such as: the acceleration of the growth rate of global exports of educational services, the decline in the share of the United States and the growth of the share of the UAE in the global educational services market, the transformation of Asian countries from donors to recipient countries of educational services.

Applications of Robot Staff in Hotels

Service robots are being increasingly employed as hotel staff in the hotel industry. This study explored how hotels can better use and implement service robots for their operation. Four hotels using robots as their staff are chosen as examples for investigating what positions the robot staff do and the comments from customers. It was found that the acceptance of robots in delivering transfer services (eg. Carrying luggage, delivering room service, etc.) are higher than when they provide services at the front desk. These results demonstrated that customers have expectations in engaging with heartwarming interaction with staff when they stay in the hotel, which the robot staff are not providing such interaction in current technology. Therefore, it is suggested that the hotels can arrange the robot staff with the position that do not interact with customers in the current stage. The robot staff can assist the human staff in providing service until they can develop a sophisticated system in two-way interaction.

Clinical and laboratory features of the course of the urinary tract infection among children in the first three years of life at the current stage

Objective: To study main clinical and laboratory peculiarities of the course of urinary tract disease among children aged from newborns to 3 years old.Methods: Research design is a prospective controlled clinical research. 102 (60.71±3.77 %) children having urinary tract infection without accompanying abnormalities of the urinary system development were included in the first group. 66 (39.29±3.77 %) children having infection of the urinary tract amid congenital kidney defect.Results: Comparative evaluation of the results of complex examination of both groups showed that urinary tract infection is characterized by intoxication, pain and dysuric syndroms. The presence of accompanying kidneys and urinary tract abnormality development defined the latent course of the disease in every second child (59.09%) and supports the early development of renal infection (during first six months after birth).Conclusions: It’s necessary to conduct the search of diagnostics markers and predictors of the infection of the urinary tract among children of the first years of life, especially if there is an abnormality of the organs of urinary system.

Developing an Amplification Refractory Mutation System-Quantitative Reverse Transcription-PCR Assay for Rapid and Sensitive Screening of SARS-CoV-2 Variants of Concern

The current stage of the pandemic, led by SARS-CoV-2 variants of concern (VOCs), underscores the necessity to develop a cost-effective and rapid molecular diagnosis assay to differentiate the VOCs. In this study, over 1 million SARS-CoV-2 genomic sequences of high quality from GISAID were analyzed and a network of the common mutations of the lineages was constructed.

Possibilities of cytological diagnostics in gynecology. Human papillomavirus as an interdisciplinary problem

The article presents an analysis of current information on the etiology, pathogenesis, laboratory diagnosis of human papillomavirus. It is shown that at the current stage of development of laboratory diagnostics there is a reliable screening test — cytological examination of smears taken from the ecto- and endocervix. To diagnose HPV, a combination of microscopic (cytological studies) and molecular genetic (PCR) diagnostic methods is used.

To the question of modernity and corresponding representations of subjectivity: “dividual” and social organizations

This article is part of the extensive research of value characteristics of IT community and their potential for innovative development. In view of this, the author examines the problem of determination of the modern cultural situation and, as a result, deduction of the criterion that establishes what “modern” is. Based on the previously acquired conclusions (according to which, such criterion is the consideration of irreducible multiplicity, and the major risk is the loss of autonomy by individuals), the author aims to find the model of subjectivity that would be simultaneously multiple and autonomous. The search for the model that meets such criterion is carried out through referring to the control technologies developed within the framework of third-order cybernetics. The novelty of this article consists in peculiarity of the approach towards solution of the set task: the question in the form and method of determination of modernity has been first raised and  solved within the framework of the Russian academic philosophical community at  the previous stage of research, which determines the relevance at the current stage as well. Comparison of the developments of Russian and foreign authors reveals the parallelism between the development of cybernetics and psychoanalysis; demonstrates the conceptual intersections of the third-order cybernetics and schizoanalysis; establishes the conformity between the subjectivity of the individual and the type of organizations they are engaged in. The article offers the concept of “dividual” as a model suitable for solution of the set task. The conclusions is made that the existing potential of the IT community for modernization is neutralized in the context of transition towards the hierarchical structure of the organization.

theoretical framework for impact assessment of the labor code on enterprises

Labor law plays an important role in regulating the relationship between employees and employers. The Labor Code has made more effective adjustments to enterprises to ensure the interests of employers. However, some regulations still do not meet the requirements set out at the current stage. The article researches the theoretical framework to assess the impact of the Labor Code on enterprises to reflect between the legal theory and the actual law implementation. On that basis, the article will propose solutions to improve the provisions of the Labor Code for enterprises to establish a solid legal corridor to ensure the development of enterprises in the current period.

On Some Developmental Trends for The Russian-Mongolian Relationships

This article made available for publication is compiled on the basis of a report presented at the International Science Conference that took place on September 2nd, 2021, in the city of Vladivostok (Russky Island). It deals with the ordinary and megatrends reflecting the specific aspects in relation to the current stage of the Russian-Mongolian bilateral relationships. Such trends include, for example, diversification of external ties or orientation towards multidimensional collaboration. It is asserted that, throughout the century-old history of close interaction between Russia and Mongolia, since the establishment of diplomatic relations between the two states, there have been a lot of epoch-making events and developments of landmark nature, which up to date constitute the meaningful elements of historic memory for our peoples, defining the overriding megatrend of our mutual understanding and affinity that bears a sustainable character, defying any influence of the political and economic environment factors.

The spatial adaptation of farming systems to the heterogeneity of plots

The full exploitation of the resource potential of arable lands was analyzed in the research. The problem of completeness of the use in different farming systems was considered. It was found that at the current stage of development of farming systems, the diversity of soils and lands and, accordingly, their resource potential were most successfully incorporated in adaptive-landscape farming systems and precision farming systems. Undoubtedly, the cost of precision farming systems will decrease in the future due to the cheapening of technical means. But without introducing scientific and methodological justification for accounting of diversity of soils and land plots (as in adaptive-landscape farming systems) and heterogeneity of crops into precision farming systems, increasing the completeness of land resource potential cannot be achieved. Another important direction to improve the full use of the land resource potential is the development of a new scientific direction - Econics, and the development of technologies for leveling the heterogeneity of fields. But these directions are at the very beginning of their development.
