In the present manuscript, we highlight the contradictions in the thermally activated processes theory which treats a system's activated state as a state of the phonon subsystem. We offer an alternative model, in which the activated state is treated as an electron subsystem state. The mechanism of the activated state formation is as follows: thermal fluctuations excite electrons of some particles within the activation zone.

Background: The work studied and compared the dynamics of changes in the course of hypertension, type 2 diabetes, and somatized disorders in Ukrainian population, in the 1st period before war (October 2021 - February 2022) and 2nd period during the war (March -July 2022). The choice of the study of the above-mentioned nosology is due, first of all, to the increase in cases of referrals to outpatient doctors regarding hypertensive crises, the increase in the frequency of patients' complaints about the lability of glycemic indicators during routine monitoring of glucose levels with ambulatory glucometers, the appearance of chronic pain syndrome of unspecified pathology with the beginning of war events.
Methods: 272 people were examined in Mykolaiv Region (Ukraine).

Real-time systems are widely used in industry, including technological process control systems, industrial automation systems, SCADA systems, testing, and measuring equipment, and robotics. The efficiency of executing an intelligent robot's mission in many cases depends on the properties of the robot's sensor and control systems in providing the trajectory planning, recognition of the manipulated objects, adaptation of the desired clamping force of the gripper, obstacle avoidance, and so on. This paper provides an analysis of the approaches and methods for real-time sensor and control information processing with the application of machine learning, as well as successful cases of machine learning application in the synthesis of a robot's sensor and control systems.
