Tracing the way the information acts on the human psyche and physiology

Dear readers!

The present issue of our journal is of very special nature. We are constantly analyzing not only the readers’ focus of interest to the publications in our journal, but we are also tracing how cardiometry as a new science is realized by medical doctors and how they apply it in their practice.

Report

The article is devoted to a novel noninvasive measurement of parameters of metabolic processes in the cardiac muscle fiber cells upon an original ECG processing. Theoretically substantiated is an original method of the ECG cardiac cycle phase analysis, which allows measuring the concentration of oxygen, lactate and phosphocreatine in arbitrary units in the cardiac muscle fiber cells in each cardiac cycle.

Original research

This article presents some results of processing of phonocardiography signals (PCG signals) for cardiac cycle tone identification under ambient noise of varying intensity. For PCG signal processing, proposed is a refined approach based on active band pass filter bank, which allows improving an accuracy of cardiac cycle tone identification under ambient noise.

Report

This paper offers some results obtained in our studies on the motion of individual formed elements in blood with due regard of a pulsatile flow of the plasma in the blood vessels. An analysis of the process of the motion of the blood particles having different shapes in a pressure wave variable field of the pressure wave has been completed herein.

Review

A review and a critical analysis of the specialized literature on justification for the measurement equation and an estimation of a methodical error (uncertainty) of the measurement result are presented in the paper, and some prospects for solving of the issue are discussed herein.

The aim of our study is to empirically verify the conceptual possibility of constructing a taxonomy of diverse domestic situations, which may become the basis for choosing the best ways to increase an individual stress resistance in a human subject.

Original research

The limitations of capabilities of the existing mathematical weather prediction (including forecasting for weather-sensitive individuals) cannot be duly realized nowadays due to the fact that till now there is no proof of the existence and uniqueness of smooth solutions of the three-dimensional (3D) Navier-Stokes equation (in any finite period of time).

Axiomatics is method of science formation used in all natural science. The axiomatcs objective is to prove that the observed phenomenon represents the varity. Further on, the proved phenomenon is used in the function of the logical ratiocination for further conclusions.

Original research

The article presents the results of an experimental study on the use of cardiometry and oculography to detect concealed information. It has been shown that a complex assessment of the person’s emotional-cognitive state based on cardiometric and oculographic recording of reactions to specially selected stimulus material of visual and audial modality can be successfully used in concealed information detection.

Analytical Note

The cardio-oculometric detection (COD) is an integrated method aimed at studying personal preferences, individual traits and current functional states of a human individual. The method is based on the use of some cardiac markers and parameters of oculomotor activity in response to specially selected visual and audial stimuli.
