“…It is instructive to relate the above probabilistic model of single-particle diffusion through a semi-permeable barrier to a recent study based on a Fokker–Planck description [20]. The latter was derived by taking a continuum limit of a continuous-time random walk model with a defect.…”

“…Another possible extension could be to discrete heterogeneous diffusive processes with resetting, for which the continuous limits with position-dependent diffusion coefficient have been recently analysed [85]. One may also study the discrete resetting dynamics in presence of permeable interface, for which a fundamental diffusion equation in the continuous limits has been derived from microscopic description very recently [86]. using a sum of terms as follows The first term on the right-hand side of Eq.…”
