Russian scientists at Siberian Federal University, together with foreign colleagues, have developed a way to predict the onset of a crisis in the human body and other complex systems. The method for determining the tensile strength of living organisms using adaptation models is reported in an article published in the journal Physics of Life Reviews.
It is known that with an increase in the load from environmental factors during a crisis and even before the onset of obvious signs of stress, the correlation between various parameters of complex systems increases. Over the course of 30 years, this effect has been supported by numerous observations of groups of people, mice, trees, herbaceous plants, and financial time series. Over the past decade, these findings have been complemented by many new experiments ranging from gene networks to the dynamics of depression and clinical psychotherapy.
Several systems of models have been developed: the thermodynamic theory of ensemble adaptation and several families of individual adaptation models. In the new work, the researchers analyzed correlation graphs, which allow one to designate pairwise connections between objects of a certain set. It turned out that during adaptation to stress factors, the behavior of these connections is universal, regardless of the sets of parameters. This makes it possible to calculate and predict the onset of a crisis moment when the influence of environmental factors will have a negative impact on a living organism.
