На основе 2-(пиперазин-1-илметил)-9Н-тиоксантен-9-он-S,S-диоксида и метакрилоилхлорида синтезирован 2-[4-(2-метакрилоил)-пиперазин-1-ил-метил]-9Н-тиоксантен-9-он-S,S-диоксид 1, представляющий собой электрохимически активный мономер, последующая радикальная сополимеризация которого с метилметакрилатом приводит к электроактивному сополимеру (PMMA-co-ThxSO2) с соотношением метилметакрилатных фрагментов цепи и пендантных (боковых) групп 9Н-тиоксантен-9-он S,S-диоксидной структуры, равным 95 : 5 соответственно. Методом циклической вольтамперометрии показано, что электрохимическое восстановление (ЭХВ) соединения 1 в ацетонитриле (MeCN) является двухэлектронным двухстадийным процессом с образованием долгоживущих анион-радикала на первой одноэлектронной стадии и нестабильного дианиона на второй стадии. Электрохимическое восстановление PMMA-co-ThxSO2 связано с восстановительной электрохимической активностью пендантной группы, а его механизм сходен с механизмом ЭХВ мономера 1. Данное соединение представляет собой полимер с пендантными группами, играющими роль эффективных ловушек электронов при транспорте заряда внутри тонкой пленки сополимера, и может быть использован в технологиях резистивной памяти (ReRAM – Resistive Random Access Memory) в качестве активного рабочего слоя мемристоров.
2-[4-(2-Methacryloyl)-piperazine-1-ylmethyl]-9H-thioxanthen-9-one-S,S-dioxide 1, an electrochemically active monomer, has been synthesised from 2-(piperazine-1-ylmethyl)-9Н-thioxanthen-9-one-S,S-dioxide and methacryloyl chloride. Subsequent radical copolymerisation of the synthesised compound with methylmethacrylate leads to an electroactive copolymer (PMMA-co-ThxSO2) with the ratio of methyl methacrylate fragments in the chain to the pendant (side) groups of the 9Н-thioxanthen-9-one S,S-dioxide structure equal to 95 : 5, respectively. It has been shown by cyclic voltammetry that the electrochemical reduction (ECR) of 1 in acetonitrile (MeCN) is a two-electron and two-stage process, with the formation of long-living radical anion at the first one-electron stage and unstable dianion at the second stage. Electrochemical reduction of PMMA-co-ThxSO2 is due to the reductive electrochemical activity of the pendant groups, and its mechanism is similar to the ECR of monomer 1. This compound is a polymer with pendant groups that play the role of efficient electron traps during charge transport inside the thin copolymer film, and it can be used in the resistive memory technologies (ReRAM – Resistive Random Access Memory) as the active working layer of memristors.
A decomposition analysis of Agents
Authors: Chen Mingjiang 
Published: September 2024

Agents and Causers are standardly analyzed as external arguments introduced by v or Voice. According to this approach, the two arguments are independent and unrelated. However, evidence from the distribution patterns of various adjuncts (nonarguments) in change-of-state verbs suggests that the verbal structure provided by the standard analysis is not fine-grained enough and requires revision. To address this issue, I propose decomposing the Agent-introducing head (v or Voice) into Voice and Appl. Specifically, I suggest that Voice introduces Causers, while Appl introduces Affectees. Both arguments are atomic and primitive, meaning that they cannot be further divided and are capable of combining with each other to form other types of arguments. I argue that Agents are derived through movement from Spec, ApplP to Spec, VoiceP, and are therefore composite, consisting of both Causers and Affectees. This decomposition analysis offers a new perspective on the Animacy Restriction observed in aspectual si constructions and ditransitive alternations. Compared to the standard analysis, it accurately predicts that Agents alternate with Causers and Affectees. Additionally, it naturally extends to unergatives.

Authors: Varlamova J. A. , Korneychenko E. N. 
Published: September 2024

Objective: to provide a comparative assessment of the use of artificial intelligence technologies by organizations in the context of Russian regions and to identify determinants of their dynamics. Methods: descriptive statistics, histogram, grouping, principal component method, panel data models. Results: an absolute trend of recent years is to study and implement artificial intelligence technologies in many economic, industrial processes and social life. The article analyzes the trends in the application of artificial intelligence technologies in the Russian regions. The comparative analysis of regions by the level and growth rate of artificial intelligence technologiesuse by organizations showed that the regions were heterogenous by the dynamics of this indicator in 2020-2022. The regions were divided into four groups: above average and below average level in Russia. Econometric modeling based on the method of principal components gave grounds to unite the determinants of the use of artificial intelligence technologies into four components. Panel data fixed-effects models showed a significant impact of the component, characterizing the state of human capital, the level of economic development, and innovation activity of organizations in the region. Scientific novelty: for the first time an attempt was made to provide a comparative analysis of Russian regions by the level of artificial intelligence technologies use by organizations and to find the determinants of its change. Practical significance: the heterogeneity of regions in terms of the artificial intelligence technologies use by organizations was substantiated, as well as a great impact of the specific characteristics of regions, which should be taken into account when building a national policy of artificial intelligence development.

Assessment and comparison of tourist potential and public ratings of regions for the regional tourist market development (by the example of Orel region)
Authors: Shmarkov M. S. , Shmarkova L. I. 
Published: September 2024

Objective: to develop and test the method of estimating a tourism potential of regions, the method of comparing them with public ratings of regions; to diagnose problem areas of management when forming the regional market of tourist services and justify recommendations for its development. Methods: general scientific and general logical methods, analysis, synthesis, comparison, generalization; statistical and correlation analysis. Results: the paper presents the author’s method of constructing summary estimates of the regions’ tourism potential, integrating official statistical indicators. Due to the introduction of dimensionless relative values, the difficulties of accounting for different-sized indicators were resolved. The obtained estimates were used to form an objective idea of the strength of the regions’ tourism potential, to compare them, to assess the opportunities and determine the prospects for tourism development in the region. Since one of the obstacles in solving this task is low public ratings, it is important to be able to compare them with objective assessments. For this purpose, we have developed and tested a method of comparing the summary estimates of the regions’ tourism potential with their ratings, in particular, with the values of the National Tourism Rating – 2022. As a result, by the example of Orel region, the disproportions were revealed that indicate the inefficient use of the region’s tourism potential. Based on the analysis of the regional strategies implementation, programs and practices of tourism organization and problem areas of management, recommendations are formulated, the implementation of which guarantees the economic development of the region and tourism sphere. Scientific novelty: the method of constructing summary estimates of the regions’ tourism potential is developed; the method of comparing the summary estimates of tourism potential with public ratings of regions is proposed and tested. The disproportions in assessments and ratings are substantiated quantitatively. The problem areas of management in the formation of the regional tourist services market are diagnosed; recommendations for its development are given. Practical significance: the study results can be used by business entities and authorities to formulate strategies and programs of regional development; the presented method of comparing the tourism potential and ratings of regions can be used in scientific, pedagogical and research activities.
Introduction of a guaranteed basic income as a probable consequence of intellctual automation of labor
Authors: Filipova I. A. , Steshina O. M. 
Published: September 2024

Objective: to form a holistic view of the unconditional basic income as a tool of social protection, taking into account the changes in the labor sphere and allowing to solve a number of growing problems associated with the consequences of the economy digitalization, as well as to assess the prospects of creating legal regulation on this issue. Methods: the study was conducted using both general and specific scientific methods, including analysis and synthesis, formal-legal method, systemic and comparative approaches, methods of legal forecasting and legal modeling. Results: unconditional basic income can become one of the elements of a new model of social security based on the unstable nature of labor relations, which begins to prevail over the model of sustainable employment traditional for industrial society. If established, this institution will be cross-sectoral within the labor law and social security law, providing social protection simultaneously to all members of society, most of whom in the near future will face an increased risk of being absorbed by technological unemployment. Unconditional basic income as an element of the social protection system will have to comply with the principle of the universal nature of protection based on social solidarity, on the one hand, and to take into account the need to balance the interests of the parties, on the other hand. As experimental models of basic income, which can be put into practice in the coming years, we can name the model of basic income as a measure of social support for persons involved in atypical forms of employment. This model will affect a number of existing provisions of labor legislation and will allow over time, in case of technological unemployment, to expand the circle of unconditional basic income recipients to all people. Scientific novelty: it consists in the fact that the unconditional basic income is analyzed from the viewpoint of its compliance with the fundamental principles of labor, employment, and social security. Practical significance: it consists in revealing the significance of basic income for the implementation of social policy and in forming recommendations for modeling experiments to introduce the unconditional basic income in the Russian Federation.

Abstract

Nowadays, the development of transportation industry and urban traffic has resulted in soil, water and air pollution. Tehran is also one of the polluted cities. In this air, heavy metals such as iron, zinc, lead, cadmium, chromium, arsenic and nickel enter the human body system through inhalation, leading to problems for citizens. The use of falling dust is known to be a suitable and effective method for monitoring and measuring air pollution. Therefore, in this study, the amount of heavy metals Fe, Cd, Cr, As, Ni, Pb, and Zn was measured in each of the 22 districts of Tehran to evaluate the amount of contamination. For this purpose, 88 sampling points were considered in the entire city. Sampling was done in three months of winter 1400. Samples of surface dust were collected using pen brushes from the side of the main streets. Then, after preparing the samples (including drying, powdering and digesting), the concentration of the desired heavy metals was measured using an ICP-MS device. Then the indices of enrichment factor (EF), contamination factor (CF) and Geoaccumulation Index (Igeo) were calculated. Finally, the results obtained from the concentration of the studied metals were used to present the spatial pattern of the concentration of heavy metals using GIS software and inverse distance weighting (IDW) technique. The results showed that the highest concentration of all types of metals belongs to the central, south and southeast parts of Tehran. Also, among different elements, iron and then chromium have the highest average amount of pollution.
Multiomics Reveals Alterations in the Gut Microbiome, Host Proteins, and Host Metabolites Correlating with SADS-CoV Pathogenicity and the Immune Response in Piglets

Abstract

SADS-CoV, a coronavirus, is known to induce swine acute diarrhea syndrome. To explore the differences and commonalities in the pathogenesis mechanisms between highly pathogenic and low-pathogenic strains of SADS-CoV, we conducted an integrated analysis comprising proteomics, metabolomics, and short-chain fatty acid (SCFA) analysis, along with 16S rRNA sequencing of intestinal mucosa and fecal samples from piglets infected with SADS-CoV P7 (highly pathogenic)or SADS-CoV P83༈low-pathogenic༉. Additionally, we examined molecular events linked to potential pathogenicity and host immune responses subsequent to correlational analysis of diverse omics data. In the SADS-CoV P7-infected group, the abundance of unidentified members of the family Enterobacteriaceae was markedly greater than in either the control group or the SADS-CoV P83-infected group in the ileum mucosa and feces. The concentration of SCFAs was significantly lower in SADS-CoV P7-infected pigs than in SADS-CoV P83-infected pigs, and SCFA levels were negatively correlated with the abundance of Enterobacteriaceae and the abundance of the species Escherichia coli in the ileum mucosa. Compared to those in the SADS-CoV P83 group, the differentially expressed proteins in the SADS-CoV P7 group were predominantly linked to extracellular matrix (ECM)-receptor interactions and focal adhesion pathways. Following SADS-CoV P7 infection, there was an increase in both the adhesion force and the number of Escherichia coli O157 adherent to IPEC-J2 cells. Moreover, SADS-CoV P7 can modulate the adhesion of E. coli O157 to IPEC-J2 cells by regulating the expression of the ECM-related protein integrin alpha5 (ITGA5), suggesting that ITGA5 plays a pivotal role in the invasion of E. coli O157 into intestinal epithelial cells during SADS-CoV infection. A correlation exists among the multiomics profiles of the small intestinal mucosa and feces of piglets following infection with various generations of SADS-CoV. Understanding this correlation can help us better prevent the virus from harming piglets.
