作者： A.a.viktorov State Research Center Burnasyan Federal Medical Biophysical Center of Federal Medical Biological Agency MoscowRussia

On the basis of the basic model of the kinetic theory of aging of living systems,mathematical modeling of various characteristics of aging of mankind,state,generation,human body,organs and cells has been carried *** results are compared with experimental and calculated data of other *** analysis of the works presented here and those carried out earlier gave reason to believe that the basic mathematical model of the evolution of aging of living dynamic systems of various hierarchical levels and nature is the invariant differential equation of the kinetic theory of aging,as a manifestation of the fractality property of living systems.

The Predictive Potential of the Kinetic Model of Aging of Living Systems in Demography

Journal of Geriatric Medicine 2019年第2期1卷 1-7页

An original mathematical model,previously tested by the authors on other non-demographic objects,is proposed for describing and forecasting demographic systems—the population of the countries of the World using the examples of the USA,China and Russia,as well as the number of mice in the“mouse paradise”experiment of the American scientist John *** proposed approach allows us to describe the stages and features of this dynamics:population growth in the USA,growth and possible decrease in the population in China,loss of a part of the population of the Russian Empire and the USSR due to two world wars and the collapse of the USSR,biological degradation of the“mouse paradise”up to its complete *** use of the kinetic model of aging of various types of living systems to predict the development of the number of demographic systems is based on the assumptions that the aging and development processes are related to each other and have the same statistical regularity,reflecting the fractal principle of Nature-the unity of structure and *** results obtained suggest that a person,a population of the World,humanity and other biological species develop and simultaneously age like each other under the conditions of the always existing syndrome of general adaptation(stress)and according to the same pattern corresponding to the mathematical model proposed here.
