The decision model of identification of significant diagnostic characters (order parameters) is presented within using of neural network decision model for binary classification (division of a group of subjects being in two different ecological and psychic conditions). Similar problems are the basis of cognitive and heuristic activity of a human who has to identify order parameters in any process and analysis of any events. We have shown that the possibility of order parameters identification (significant хi) is low in a small number of iterations (p<100) with initial weight characters xio based on uniform distribution (xio from an interval (0,1)). If p increases (p>100, p>1000), accuracy of order parameters identification increases too. Within the frameworks of the model there is a hypothesis on the connection of reverberation in hippocampus with efficiency of a heuristic brain activity.
The problem of one-type uncertainty is solved when cardiovascular system parameters in hypertensive patients undergoing physiotherapy aren’t differentiated by stochastics, but these differences are clearly revealed by the methods of neurocomputing and calculation of parameters of quasi-attractors. Simultaneously, the solution of system synthesis problem is possible, i.e. identification of more important diagnostic characters xi from the whole set of state vector of cardiovascular system x(t) in hypertensive patients. Efficiency of physiotherapy is estimated at two stages of course of treatment: in the initial state (initial physiotherapy) and after the termination of course of treatment. The dynamics of motion of quasi-attractors in phase space of states in hypertensive patients is shown. Thus, the problem of elimination of one-type uncertainty in studying the effi-ciency of curative measures is solved.
Accoding to new third paradigm (which is based on the calculations on calculation of quasiattractor parameters of human body state vector) we are presented formal models and methods of calculation of quasiattractor moving in the phase spaces of state. It is shown that a single therapeutic procedure may not demonstrate significant changes of the parameters of the state vector x(t) in phase m-dimensional space with the positions of the stochastic approach. However, new methods of chaos theory-self-organization (TCS) will always show such changes, if to count or change the volume VX of quasiattractor, or the coordinates of its center HS and speed υ movement of this center. Examples of this approach in medicine and human ecology, when stochastic is not able to detect differences between samples, and new methods are demonstrated. In this case, it is advisable to use the computer in the mode of multiple iterations or calculate parameters of quasiattractors and values approach their centers in the phase spaces of States. It is essential that such methods should be used in the evaluation
To solve the problems of gerontology this review presents the detailed description of the choices of the many signs as the most significant for the assessment of functional systems of the organism. The authors have justified the expediency to abandon the deterministic and stochastic approaches to complex systems - complexity. The possibilities of chaos theory and self-organization systems have been described in detail. The review provides a description of the capabilities of nano-emulsion, neuro-computing, method of calculation quasi-attractors for the solution of problems of system synthesis to identify order parameters. The authors presented data on the use of these methods for different age groups of women Khanty living in the North of Russia. The necessity to increase the number of iterations (settings) neuro-motor to increase the precision of separation of the samples was established. The authors proposed to implement the methods of chaos theory and self-organization in the practice of gerontology.
This review focuses on spinal and central mechanisms of fatigue associated with the implementation of adaptation programs. The morpho-functional correlations of the moto-neurons activity of the spinal cord, the activities of the functional systems of the human body, neurotransmitter systems, serotonergic, dopaminergic and noradrenergic systems in the mechanisms of fatigue were considered. The phases of the process of adaptation to physical loads as well as cumulative training effect were identified. The authors have identified and described the participation of the autonomic nervous system, glucocorticoids and other hormones and mediators in long-term adaptation to physical loads, in the transition from carbohydrate to fat type of energy metabolism. The stages of disadaptation and re-adaptation to physical activities (a manifestation of stress, rate adaptation, cybernetic principles of homeostasis) have been identified and described. The two-circuit system homeostasis: the autonomic (controlling) and myocardial-hemodynamic (controlled) was demonstrated and an hierarchy of control has been defined.
