Experimental Diagnostics of the Emotional State of Individuals Using External Stimuli and a Model of Neurocognitive Brain Activity

In this paper, we study ways and methods to diagnose the emotional state of individuals using external audiovisual stimuli and heart telemetry tools. We apply a mathematical model of neurocognitive brain activity developed specifically for this study to interpret the experimental scheme and its results. This experimental technique is based on monitoring and analyzing the dynamics of heart rate variability (HRV), taking into account the particular context and events occurring around the subject of the study. In addition, we provide a brief description of the theory of information images/representations used for the paradigm and interpretation of the experiment. For this study, we viewed the human mind as a one-dimensional potential hole with finite walls of different sizes and an internal potential barrier modeling the border between consciousness and subconsciousness. We also provided the foundations of the mathematical apparatus for this particular view. This experiment allowed us to identify the characteristic markers of influencing external stimuli, which form a foundation for diagnosing the emotional state of an individual.

Modern Approaches to Acellular Therapy in Bone and Dental Regeneration

An approach called cell-free therapy has rapidly developed in regenerative medicine over the past decade. Understanding the molecular mechanisms and signaling pathways involved in the internal potential of tissue repair inspires the development of new strategies aimed at controlling and enhancing these processes during regeneration. The use of stem cell mobilization, or homing for regeneration based on endogenous healing mechanisms, prompted a new concept in regenerative medicine: endogenous regenerative medicine. The application of cell-free therapeutic agents leading to the recruitment/homing of endogenous stem cells has advantages in overcoming the limitations and risks associated with cell therapy. In this review, we discuss the potential of cell-free products such as the decellularized extracellular matrix, growth factors, extracellular vesicles and miRNAs in endogenous bone and dental regeneration.

A robust single device MOSFET series resistance extraction method considering horizontal-field-dependent mobility

A simple MOSFET series resistance extraction method using multiple drain current vs. gate voltage curves of a single device is proposed, where mobility modulation by horizontal electric field (i.e., weak velocity saturation) is taken into account. The method is validated using TCAD, where series resistance determined from internal potential distributions was used as reliable reference. Measurement results were also obtained which further support the validity of the method.

Lexical Units with Functionalverbs for German Language Development in a Historical Context

The existance of functionalverbs is confirmed by scientists at different stages of German language development. An event whose origins are recorded in the early stages of language development is not uniwue to the German language. The fact, that the number of words in the German languagr has been increasing over the centuries confirms the tendency of its development from a synchronic to an analytic structure. In the process of diachronic language development, there are certain periods when the tendency of nominalization and use of words is more pronounced than in other sections. The development of functionalverbs into a systemic phenomenon is thought to have taken place in the XVIIIth century. They are recorded in the scientific literature and the language of governance, as well in the fiction.There was a development of the German language’s internal potential and analytical structure in the face of changed living conditions.Many factors contribute to the widespread use of functional expressions in Modern German. They are found is almost all functional styles: mostly in pfficial, scientific and press languages, as well as in fiction.

Research and Application of Standard Oil Dispensing System for Dissolved Gases in Transformer Oil

Measuring the content of dissolved gas components in transformer insulating oil by gas chromatography is an important means to judge the internal potential faults of oil filled electrical equipment in the process of operation supervision. The necessary work skills of power grid operators include the ability to detect the content of dissolved gas in transformer oil and judge the operation state of transformer. This paper introduces a preparation method and equipment of transformer standard oil. It can quickly prepare standard oils with various gas component contents. The standard oil quantity value is accurate, the data stability period is greater than 90 days, and the uncertainty is less than 5%.

Progressive limit state at critical levels of internal potential energy of deformation

Introduction. The work is devoted to one of the main issues of structural mechanics - the determination of the elements in which the limiting state occurs first. At first glance, the task has an infinite number of results, meaning an infinite number of options for loading the system. The problem becomes solvable if one examines the structure of a building (structure) for possible variations in displacements (forces) in the nodes of the structure. For this approach, it becomes possible to determine the main values and vectors of displacement of the system, which correspond to the maximum (minimum) values of deformations (forces) in the rods of the system. As close approaches to the formulation of the problem, one should indicate the theory of the limiting equilibrium of structures under the assumption of the work of the material under flow conditions, where the equality of the work of external forces and internal forces is considered (kinematic method), or possible static stress states of the system for maximum limiting loads (static method). The theory of protecting buildings and structures from progressive collapse seeks to solve similar problems, focusing on options for design solutions that prevent destruction from non-design loads. Materials and methods. To determine the options for the distribution of extreme values of internal forces (deformations) in the system, the problem is formulated in the form of an eigenvalue problem. The latter turns out to be the most convenient mathematical model of the problem, since, in addition to extreme values (as in the optimization problem), it allows one to take into account the values of the problem on the upper and lower bounds. The theoretical basis for the formulation of the problem is the criterion of the critical levels of the internal potential energy of the system, which makes it possible to find the self-stress states of the structure corresponding to the limiting states of the structural elements. Results. The methodology for solving the problem is illustrated by the example of a statically indeterminate five-rod truss, which was also considered by other authors. The matrix formulation of the problem and a detailed algorithm for its solution are given. It is shown that the values of the internal forces in the rods, obtained using the traditional method, are in the interval between the maximum and minimum main values of the self-stress state of the system. Solutions are given at each of the critical energy levels corresponding to the disconnection of bonds from work.

Management of internal reserves of reducing product cost (on the example of JSC “Plant of Drilling Equipment”)

Due to tough competition and economic sanctions domestic mechanical engineering enterprises are in a permanent search of sources of increasing their performance efficiency. One of such sources is the internal potential of a company. Engineering enterprises possess a large stock of internal reserves and their exploitation provides the businesses with competitive advantages in the global market. Internal reserves are the source of a company’s investment. Reduction of production costs at the expense of internal reserves is an important direction of increasing an engineering company’s performance efficiency. Currently, there are no universal methodical tools to manage internal reserves of reducing production costs at the mechanical engineering enterprises. The study is aimed at describing the process of management of internal reserves of reducing production costs which is applied at one of engineering plants. The author outlines the experience of an mechanical engineering company on managing internal reserves of reducing production costs. It is based on the marginal analysis method which makes it possible to find a product with high margin profitability. The author adduces the sequence of all stages of the management process and the calculations on certain types of products, and reveals reserves for reducing production costs according to the directions of search for them. The experience presented in the article will be a good example for the other engineering enterprises and will provide them with the opportunity to reduce production costs and increase their performance efficiency avoiding any borrowed funds.

Economic Security within the Limits of Economic Complexity

Introduction. The issues of ensuring economic security of regions (especially of those with a specific situation) taking into account the influence of economic complexity are a novel research problem. The development of regions, primarily the border ones, is determined by two divergent processes: growing economic complexity, determined by external constraints or opportunities, and economic security, associated with the internal potential and resources of the region. Based on the study conducted, the article reveals the features of the interconnection between economic security and economic complexity, the latter determining the innovative and technological limitations to the growth and development of territories. Materials and Methods. The author has conducted semantic analysis and thematic clustering of economic security using data from bibliographic and reference databases of publications in English (Web of Science) and in Russian (eLIBRARY.RU). The assessment of economic complexity was based on the conducted analysis of the UN Comtrade foreign trade statistics, that of economic security – on the official data published by Rosstat. Results. The author has identified the terminological connection between economic security and economic complexity, and has provided a theoretical representation of the relations and interdependence of these categories. The paper presents the methodological provisions for studying the economic security of border regions, taking into consideration the possibilities for increasing their economic complexity. Discussion and Conclusion. In the context of systemic constraints in the development of the region, economic security is largely determined by both the available internal potential and resources, and the possibilities of their use. However, the region gains new capabilities with the increase in its economic complexity, the latter also limiting its economic security. In fact, the choice of key areas for the structural transformation of the region’s economy depends on whether priority is given to maintaining the level of economic security or increasing economic complexity. The mechanism and criteria discussed in this paper, as well as the methodological provisions of such a choice, contribute to further development of the theory of economic security and economic complexity at the regional level and are of practical importance for regional governance.

Extracurricular Activities Are A Key Element In The Organization Of The Educational Process

The article describes the factors, conditions, the principle of communicative activity (as a component of the principle of activity), signs, opportunities in creating conditions for the development of many areas of the student's personality, goals, objectives, content and forms of extracurricular activities. A systemically organized extracurricular lesson includes methods of teaching, upbringing and development that stimulate students to master knowledge and skills on their own, and also disposes to more informal interaction with teachers, which leads to the disappearance of the framework of the formal relationship and the disclosure of the internal potential of students.
