Conservation laws of metabolism and mortality

Azbel’, Mark Ya. - In: Physica A: Statistical Mechanics and its Applications 329 (2003) 3, pp. 436-450

Quantitatively accurate laws of metabolism and mortality, which are the same for species with different evolutionary history (e.g., humans and flies), are derived and extensively verified. Such conservation (with respect to evolution, i.e., in non-stationary and heterogeneous conditions) laws...
