#1 / 2019Biological SciencesBotasheva T.L., Radzinsky V.E., Khloponina A.V., Vasilyeva V.V., Zavodnov O.P., Zheleznyakova E.V., Kapustin E.A.Systematic aspects of adaptive changes in pregnant women blood depending on fetal sex We study the dependence of the blood system of the maternal organism in case of physiological pregnancy on the gradation of the “fetal sex”. The aim of the research is based on the fact that the stay of the fetus in the womb of the mother during pregnancy leaves a certain structural and functional trace, which affects the various sub-systems of the mother-placenta-fetus system. In this case, the sex of the fetus is an important factor that modulates the functional changes in this system. The blood system has important positions in the gestational transformations, since it is responsible for transporting nutrients and oxygen to the tissues of the child and mother. It has been found that in pregnant women with boys there is a greater tension of the links of the coagulation system, higher values of red blood cells and hemoglobin, which emphasizes the increased activity of oxygen-providing subsystems of the mother organism. In pregnant women with girls, there is a greater count of leukocytes, basophils and erythrocyte sedimentation rate, indicating a more pronounced involvement of the immune system of women in adaptive reactions in gestation.
Neurophisiological correlations of forming gestational dominant while using additional reproductive technologies Brain bioelectric activity was studied in 204 patients, who were submitted in vitro fertilization. The left-side cortical activation of the temporal and central zones of the brain of women, who became pregnant as a result of IVF program has been identified, which seems to indicate the gestation dominant formation. We offer the ways of increasing efficacy of the IVF methods based on the investigation of the mechanisms of central-peripheral integration in wom-en’s reproductive system.
Features of brain bioelectric activity in women with metabolic syndrome We study the parameters of the bioelectrical activity of the brain in patients with metabolic syndrome in various functional states in order to identify central predictors of metabolic homeostasis disorders and the development of metabolic-associated diseases. An electroencephalographic examination of two groups of women was conducted: 48 patients with metabolic syndrome, 43 without it. We revealed moderate changes in various EEG indices, indicating the predominance of the activity of nonspecific brain stem structures, changes in the balance of interhemispheric activation with a shift to the right hemisphere. The obtained data demonstrate the capabilities of the electrophysiological method for the detection of early brain predictors of metabolic disorders as additional to standardized diagnostic methods.

MathematicsZaytseva I.V., Timoshenko L.I., Bogdanova S.V., Shlaev D.V.Algorithm for finding a compromise solution for a dynamic model of human resource management Many practical tasks of economic activity and a number of important issues of economic theory are associated with the tasks of determining the optimal solution. This article proposes a game-theoretic version of the transport problem with changing conditions, that is, a problem in which the parameters of the system depend on time. For this model, the problem of finding compromise values of the income functions of all participants and the corresponding sequence of control sets that implement a compromise trajectory is solved.

On automating the determination of the vessel location in an electronic cartographic navigation and information system This scientific article deals with determining the location of the vessel – the course, speed, plotting on the chart – by means of sophisticated neural network technologies. The relevance of the topic is due to the contradiction, on the one hand, the presence of conservative methods for determining the ship’s position (“man”), and on the other, the existence of many automated navigation systems (“machine”). All the goals of the work have been implemented and can be recommended for use on the vessel.
Cyclic code selection method for reservation of parallel channels of communication It is shown that for mission-critical information systems, effective are decision feedback systems. In such systems the selected code must provide both high reliability and high data transfer rate, which is a necessary condition for optimality of the selected code. Codes having a good ability to detect and correct are able to provide high reliability. This work is devoted to the choice of optimal correction code for systems relaying information over parallel communication channels with decision feedback. The paper develops the technique of cyclic code selection for redun-dant parallel communication channels that satisfy given requirements of speed and reliability, differing from the known ones in calculation reductions. The results of numerical studies are given.
Generalization of algorithm for forecasting time series of production systems The algorithm for reconstructing the model of a non-linear dynamical system from the generated time series in combination with the Kalman filtering for data assimilation and ensemble-probabilistic modeling for perturbing the initial data does not take into account the specific nature of the production systems that is associated with the presence of data gaps in the time series being tracked. To predict the time series of production systems with data dis-continuities, it is necessary to use the cross-linking of the series at the place of inactivity, followed by correction for the amount of time shift in the cross-linking. The forecast error associated with the presence of unforeseeable downtime in the forecast period is calculated by the probabilistic path through the analysis of historical data and is entered in the time series as a time correction. This operation is realized due to the inclusion in the places of discontinuities of the initial time series of time shifts and the subsequent cross-linking of the pieces of the series. The results of the work can find practical application for planning the production activity of the companies, including for forecasting the commercial drilling speed of oil and gas wells.

On the methodology of evaluating the protection of the organizational channel of information leakage at the enterprise At present, for most enterprises, the most likely cause of information leakage is precisely its disclosure. At the enterprise there is a constant need for an objective control over the compliance with the requirements of regulatory documents for ensuring the security of information exchange. The main purpose of this article is to develop a methodology for auditing (evaluating) the security of the organizational channel of information leakage at the enter-prise. The decision support system developed for the audit of information security developed on the basis of the pro-posed method along the organizational channel allows: to provide an impartial, objective assessment of the state of security on the organizational channel for information leakage; ensure that an audit is carried out without attracting highly qualified specialists in this subject area; to identify the directions (group indicators in the directions), for which the state of protection along the organizational channel is not satisfactory; scale and complicate, as well as adapt the decision support system to conduct information security audits for a particular facility.
