Assessment of the Effects of Space Weather on the Reliability of Readings of Magnetic Inclinometers
The efficiency of subsurface resource development in the Arctic zone of the Russian Federation (AZ RF) is closely linked to the need to minimize technogenic risks, particularly those arising from the influence of space weather on navigation systems operating at high latitudes within the auroral oval. Previous studies have described the mechanisms and extent of space-weather effects on the increased measurement errors of magnetic inclinometers used in well geophysical surveys. Drawing on data from a reference magnetic station and an assessment of inclinometric measurement quality (i.e., the ratio of low-quality data to the total number of inclinometric surveys) for 2022–2024 from operating wells in the Russian Federation, this study provides a qualitative evaluation of the relative likelihood of disruptions to technological procedures caused by extreme additional errors of measuring instruments. To reduce technogenic risks during oil- and gas-well development in the AZ RF and on the continental shelf, a decision-support framework is proposed that integrates real-time geomagnetic conditions into geophysical survey processes. Statistical relationships are examined, observed deviations are assessed, and an approach to their interpretation is outlined.

Исследование активности населения на онлайн-платформах рынка труда
As more and more people turn to online labor market platforms, their behavior patterns seem to depend on certain national factors. This research compared the activity patterns demonstrated by different populations on online labor markets, i.e., dynamics, expansion, involvement peculiarities, and limitations. Conventional methods combined with economic analysis and graphical method were applied to data provided by Statista, the World Bank, the International Telecommunication Union, and the Online Labor Observatory, as well as to data obtained from of the five largest English-language online employment platforms and six non-English-language platforms (three Hispanic and three Russian). India, Bangladesh, Pakistan, and Russia demonstrated the highest population activity in terms of forming the labor supply. The article describes the factors that contribute to the intensive development of online market platforms in developing countries, as well as the difficulties and limitations faced by online workers. The integrated approach to the cross-country differentiation of online labor market platforms made it possible to formulate a set of recommendations to encourage online labor market platforms and reduce some existing restrictions.

Main stages of Russian classical literature translations into the Turkish language
Russian literature occupies one of the leading places in world literature. Every country knows and loves Dostoevsky, Tolstoy and Chekhov. These writers had a powerful impact on the entire world literature of the twentieth century. Russia and Turkey are neighbors, so knowing the culture of neighboring countries is necessary in every sense of the word. Turkey understood this back in the Ottoman period. It was in the Ottoman Empire in the 19 th century that the first translations of Russian literature into Turkish appeared. With each decade, the number of translations kept growing. Three stages are distinguished in Russian classical literature translations: 1) the Ottoman period (XIX – the first decades of the 20 th century, before the collapse of the empire), 2) the Republican period, which is divided into two stages: a) the 1930s–1980s, b) the 1990s – the beginning of the 21 st century. Each of them was largely determined by the pressing tasks of the socio-political development of Turkish society. Thus, the main objective of the article is to give a general idea of Russian literary classics translations into Turkish. This task is justified for two reasons: firstly, our insufficient knowledge about Turkish translations of Russian literature, secondly, translations of Russian literature in Turkey are currently among the rapidly developing humanitarian practices. Hence, our experience of systematization of translations, their interpretation in historical and cultural terms.

Convolution equation in space of fast decaying functions on unbounded convex set in $\mathbb R^n$
In the work we study the solvability of the convolution equation (in particular, of differential - difference equation) in the Schwartz space on an unbounded convex set in $\mathbb R^n$.
