Protein folding dynamics is often described as diffusion on a free energy surface considered as a function of one or few reaction coordinates. However, a growing number of experiments and models show that, when projected onto a reaction coordinate, protein dynamics is sub-diffusive. This raises the question as to whether the conventionally used diffusive description of the dynamics is adequate....

This paper presents a shortest path search algorithm using a model of excitable reaction-diffusion dynamics. In our previous work, we have proposed a framework of Digital Reaction-Diffusion System (DRDS)—a model of a discrete-time discrete-space reaction-diffusion system useful for nonlinear signal processing tasks. In this paper, we design a special DRDS, called an “excitable DRDS,” which emul...

QCT calculations were performed to study the behavior of energized NH2OH formed by association collision of NH2 radical with OH radical. A potential energy surface that describes the behavior of the title reaction has been constructed by interpolation of ab initio data. H2O, HON, HNO, NH3, O, H2NO, cis or trans-HONH, and H products and two vibrationally energized NH2OH and NH3O adducts were obs...
