Directionality principles in thermodynamics and evolution.
Directionality in populations of replicating organisms can be parametrized in terms of a statistical concept: evolutionary entropy. This parameter, a measure of the variability in the age of reproducing individuals in a population, is isometric with the macroscopic variable body size. Evolutionary trends in entropy due to mutation and natural selection fall into patterns modulated by ecological...
متن کاملStochastic thermodynamics: Principles and perspectives
Stochastic thermodynamics provides a framework for describing small systems like colloids or biomolecules driven out of equilibrium but still in contact with a heat bath. Both, a first-law like energy balance involving exchanged heat and entropy production entering refinements of the second law can consistently be defined along single stochastic trajectories. Various exact relations involving t...
متن کاملThermodynamics and Evolution
Biology and mathematics. Recent developments in the areas of biological research stimulate increased interest to oscillatory chemical processes. And increasing number of researchers seem to believe that the basis for the complex organizational structure of the processes that take place inside living organisms lie in oscillatory chemical reactions. As it is usually the case in growing areas of s...
متن کاملThermodynamics and evolution.
The science of thermodynamics is concerned with understanding the properties of inanimate matter in so far as they are determined by changes in temperature. The Second Law asserts that in irreversible processes there is a uni-directional increase in thermodynamic entropy, a measure of the degree of uncertainty in the thermal energy state of a randomly chosen particle in the aggregate. The scien...
متن کاملQCD Thermodynamics and Fireball Evolution in URHICs
The fireball created in an ultrarelativistic heavy ion collision is the environment in which all processes providing clues about the possible formation of the quark-gluon plasma (QGP) happen. It is therefore crucial to understand the dynamics of this hot and dense system. We set up a model in which the fireball evolution is reconstructed between two stages, the freeze-out, which is accessible b...
