Subject of research: norms of the criminal legislation of the Russian Federation devoted to bribery and the concept of an official, as well as clarifications of the Plenum of the Supreme Court of the Russian Federation on the qualification of certain crimes of corruption.

Purpose of research: to give scientifically based proposals to eliminate the problem of qualifying the actions of a medical worker, including one who is the head of a structural unit of a medical organization, as receiving a bribe.

Object of research: social relations arising in connection with the performance by a medical worker of his professional and official duties, which were studied using comparative legal, dialectical and analytical methods.

Main results of research: a justification is proposed for the need to include in the Criminal Code of the Russian Federation a rule on liability for illegal remuneration of officials of healthcare institutions.

The subject of the study: criminal law categories. The issue of criteria for classifying a certain criminal law term into a category remains problematic and debatable.

The purpose of the study: to identify the primary basic criminal law categories, to substantiate their features.

Research methods: due to the specifics of the study, the methods of system-structural and functional analysis are used as the main ones. as a methodological basis for the study. The dialectical method of cognition of socio-legal phenomena is used, as well as general scientific methods of cognition (analysis, synthesis), private scientific (formal logical, epistemological).

The main results of the study: the primary basic criminal law categories are crime and punishment. The category of criminal liability is a secondary criminal law category, since it is derived from the primary legal category of legal liability. The author formulates the signs that characterize the criminal law category.

Subject of research: methods of improving the quality of electric energy in electric networks used for power supply mainly to municipal consumers in urban areas.

The purpose of the study is to determine the most relevant methods for improving the quality of electric energy of municipal consumers, their advantages and disadvantages, as well as determining the direction of modernization.

The importance and necessity of using modern intelligent systems to improve reliability, energy efficiency and quality of electric energy i s highlighted. The key prerequisites for the introduction of smart systems for monitoring the state of the electrical network are formulated. The tasks, the solution of which is necessary for the modernization of the complex, have been identified. A proposal has been made to use artificial intelligence-based systems as the main tool for modernization.

A significant increase in the load on technical fleet objects, such as floating cranes, dredgers, dredgers, etc., causes the problem of electromagnetic compatibility. Electricity supply of technical fleet vessels is carried out from 0.4 kV shore networks for economic reasons, but the quality of electricity of the shore-to-ship power transmission does not meet the requirements of GOST 32144-2013 and the Rules for the Classification and Construction of Inland Navigation Vessels of the Russian River Register (RSRR). Physical wear and tear of technical fleet vessels exacerbates this problem.

Subject of the study: processes affecting the stability of the electrical load on the voltage of the ship's 0.4 kV network when supplying the vessel with electricity from a 10 kV shore network and violating the EMC of technical equipment.

Objective of the study: development of scientific provisions and recommendations to improve the stability of ship voltage load nodes when powered from shore networks. Research subject: power supply systems of technical fleet vessels when powered from shore power systems.

Research results: based on the conducted research, it is shown that the proposed method increases the stability of the electrical load on the voltage of technical fleet vessels when powered from shore networks, which is essential for water transport.

Subject of research. This article examines the process of data preparation for training neural network models that address the task of recognizing complex handwritten mathematical expressions and converting them into typesetting systems like LaTeX or MathML. The dataset under study is CROHME 2019, which contains images of handwritten mathematical expressions and their corresponding LaTeX annotations.

The objective of this research is to develop and describe a data preparation process that ensures correct model training and minimizes errors in numerical labels and transformations. The study focuses on the following key stages: loading and preprocessing images, parsing LaTeX annotations, linking images with their corresponding annotations, normalizing pixel values, creating and verifying the tokenizer vocabulary, and preparing the tokenizer itself.

The methods include data analysis and processing using specialized tools for working with images and text annotations.

The main outcome of this work is the creation of a dataset ready for use in training the neural network model. The prepared dataset ensures accurate alignment between images and annotations, as well as correct conversion of mathematical expressions into LaTeX code.

Subject of research: determination of the friction torque and functions of the specific intensity of heat generation in system of sliding bearings.

The purpose of the study: To develop a method for determining the friction torque in sliding bearings using temperature data. Based on computational experiments, study the influence of errors in temperature data on the solution of the inverse problem.

Methods and object of research: A system of sliding bearings made of a polymer composite material on which a rotating shaft rests is considered. A mathematical model of the thermal process in the considered system of friction units is presented, taking into account the spatial distribution of temperature and its change over time. The temperature is measured at several points in each bearing. Frictional heat generation is determined by solving the inverse heat conduction problem from the condition that the measured and calculated temperatures are close. To ensure continuous data processing and determine the friction torque during long-term tests, the inverse problem of determining the friction torque from temperature data is solved at successive short time intervals. Then the resulting solutions are «glued together».

The main results of the study: With such a restoration, the discrepancy between the specified and restored functions of the specific intensity of heat generation is 10–15 % with an error level in temperature data of 10 %. The developed algorithm for solving the inverse problem of thermal conductivity can be used to determine the friction torques in real systems of self-lubricating sliding bearings.

The Editorial Board mistakenly accepted the paper of Galai M.S., Sidorova E.S. "Modeling of the heat transfer process during thermite welding of railway rails", previously published in Volume 20, № 1 (2024) (DOI 10.18822/byusu20240254-59), and accidentally published it for the second time.

For this reason, the mistakenly re-published paper by Galai M.S., Sidorova E.S. has now been removed from Volume 20, № 2 (2024).
