Second-order error analysis of the averaged L1 scheme L1 for time-fractional initial-value and subdiffusion problems
《Science China Mathematics》2024年第7期1641-1664,共24页Jinye Shen Fanhai Zeng Martin Stynes 
supported by National Natural Science Foundation of China (Grant Nos. 12101509, 12171283, 12171025 and NSAF-U1930402);the Science Foundation Program for Distinguished Young Scholars of Shandong (Overseas) (Grant No. 2022HWYQ-045)。
Fractional initial-value problems(IVPs) and time-fractional initial-boundary value problems(IBVPs), each with a Caputo temporal derivative of order α ∈(0, 1), are considered. An averaged variant of the well-known L1...

Anomalous and Normal Diffusion of Tracers in Crowded Environments： Effect of Size Disparity between Tracer and Crowders被引量：1
《Chinese Journal of Chemical Physics》2017年第2期147-152,I0001,共7页马义丁 罗开富 
This work is supported by the National Natural Science Foundation of China （No.21225421 and No.21474099）, the National Basic Research Program of China （No.2014CB845605）.
The dynamics of tracers in crowded matrix is of interest in various areas of physics, such as the diffusion of proteins in living cells. By using two-dimensional （2D） Langevin dynamics simulations, we investigate th...
