Universal relation between instantaneous diffusivity and radius of gyration of proteins in aqueous solution
Eiji Yamamoto, Takuma Akimoto, Ayori Mitsutake +1
Protein conformational fluctuations are highly complex and exhibit long-term correlations. Here, molecular dynamics simulations of small proteins demonstrate that these conformatio…
Detection of Transition Times from Single-particle-tracking Trajectories
Takuma Akimoto, Eiji Yamamoto
In heterogeneous environments, the diffusivity is not constant but changes with time. It is important to detect changes in the diffusivity from single-particle-tracking trajectorie…
Distributional Behavior of Diffusion Coefficients Obtained by Single Trajectories in Annealed Transit Time Model
Takuma Akimoto, Eiji Yamamoto
Local diffusion coefficients in disordered systems such as spin glass systems and living cells are highly heterogeneous and may change over time. Such a time-dependent and spatiall…
Langevin equation with fluctuating diffusivity: a two-state model
Tomoshige Miyaguchi, Takuma Akimoto, Eiji Yamamoto
Recently, anomalous subdiffusion, aging, and scatter of the diffusion coefficient have been reported in many single-particle-tracking experiments, though origins of these behaviors…
Distributional Behaviors of Time-averaged Observables in Langevin Equation with Fluctuating Diffusivity: Normal Diffusion but Anomalous Fluctuations
Takuma Akimoto, Eiji Yamamoto
We consider Langevin equation with dichotomously fluctuating diffusivity, where the diffusion coefficient changes dichotomously in time, in order to study fluctuations of time-aver…
