Organisms are non-equilibrium, stationary systems self-organized via spontaneous symmetry breaking and undergoing metabolic cycles with broken detailed balance in the environment. The thermodynamic free-energy (FE) principle describes an organism’s homeostasis as the regulation of biochemical work constrained by the …

The value of c can be determined by considering the limit T → 0. In this limit the entropy becomes S = klog Ω0 where Ω0 is the ground state degeneracy. The partition function in this limit is where U0 is the ground state energy. Thus, we see that c = 0 and that: auショップ 社外品WebJeremy Tatum. University of Victoria.
