Three results are presented: First, we solve the problem of persistence of dissipation for reduction of kinetic models. Kinetic equations with thermodynamic Lyapunov functions are studied. Uniqueness of the thermodynamic projector is proven: There exists only one projector which transforms any...

concurrent decrease in the conformational entropy of the polypeptide chain. However, to provide a description that is consistent … with other natural processes, protein folding is formulated from the principle of increasing entropy. It then becomes … steeply ascending paths on the entropy landscape that correspond to steeply descending paths on the free energy landscape. The …

volatility phenomenon is by using measures based on the concept of entropy. In this paper we investigate the long memory and …. Additionally, we compare the results from conditionally heteroscedastic models with those from the entropy measures. In the latter …, we examine Shannon entropy, Renyi entropy and Tsallis entropy. The results corroborate the previous evidence of nonlinear …

We examine the existence of an invariant manifold in the phase space structure presented by a dissipative four-wave coupling. We show that, once in such manifold, the system preserves two quantities as time evolves: a quantity related to the energy of the system and another, related to the...

This paper presents a numerical study for the peristaltic flow characteristics of a Sisko fluid in a symmetric or asymmetric channel. The fluid is assumed to be electrically conducting in the presence of a uniform magnetic field. The mathematical formulation consisting of nonlinear governing...

the monomolecular chemical kinetics. For the solution of this equation a path summation formula is proved. This formula … is developed. To calculate the estimates we introduce the multi-sheeted extensions of the initial kinetics. This approach … allows us to exploit the internal (“micro”) structure of the extended kinetics without perturbation of the base kinetics. …
