Reverse-time stochastic diffusion equation models are defined and it is shown how most processes defined via a forward-time or conventional diffusion equation model have an associated reverse-time model.DOI: 10.1016/0304-4149(82)90051-5 被
Then, the reverse diffusion process successively modifies it over a few timesteps and we end up with the final product. Image by midjourney. In equation (1), we formulated the distribution for x_t conditional on x_{t-1}. For the reverse diffusion process, we’d like...
According to the kinetic theory of a solid strength, the drift velocity of the propagation medium applies a force on a ligand–receptor bond which decreases its lifetime according to the following equation [39]: (36)τr=τ0exp(E0−λfkBT), where τ0 is the inverse of oscillation ...
2.3 Nanopore models A more mechanistic approach is based on the use of the extended Nernst–Planck equation [37], which considers transport across the membrane as resulting from (i) convection generated by the pressure gradient and the coupling between solute and solvent fluxes, (ii) diffusion ca...
