Protein motion in the nucleus: from anomalous diffusion to weak interactions [PDF]

open access: yes, 2018
International audienceUnderstanding how transcription factors (TFs) regulate mammalian gene expression in space and time is a central topic in biology. To activate a gene, a TF has first to diffuse in the available space of the nucleus until it reaches a

Anomalous Extracellular Diffusion in Rat Cerebellum

open access: yes, 2015
Extracellular space (ECS) is a major channel transporting biologically active molecules and drugs in the brain. Diffusion-mediated transport of these substances is hindered by the ECS structure but the microscopic basis of this hindrance is not fully ...

Equivalence between volume averaging and moments matching techniques for mass transport models in porous media. [PDF]

open access: yes, 2010
This paper deals with local non-equilibrium models for mass transport in dual-phase and dual-region porous media. The first contribution of this study is to formally prove that the time-asymptotic moments matching method applied to two-equation models is

Graphical and numerical validation of the least-square Laplace residual power series method for fractional Fokker-Planck equations: a study of anomalous diffusion

open access: yesBoundary Value Problems
The time-fractional Fokker-Planck equations are used to provide basic modeling of anomalous diffusion and non-Markovian processes in transport that occur in physics, biology and complex systems.
