Directional-to-random transition of cell cluster migration
《Chinese Physics B》2023年第11期168-172,共5页曾阳 车丙晨 孙聃 张策 经光银 
Project supported by the National Natural Science Foundation of China (Grant Nos. 51927804 and 12174306);the Natural Science Basic Research Program of Shaanxi Province of China (Grant No. 2023-JC-JQ-02)。
Efficient cell migration is crucial for the functioning of biological processes, e.g., morphogenesis, wound healing, and cancer metastasis. In this study, we monitor the migratory behavior of the 3D fibroblast cluster...

Theoretical simulation of chromatographic separation based on random diffusion in the restricted space
《Science China Chemistry》2016年第7期824-829,共6页Jianwei Zhao Yinlu Sun Yajun Gao 
supported by the National Natural Science Foundation of China (21273113)
The diffusion behavior of particles in the chromatography is a fundamental issue of chromatographic dynamics. The understanding of the diffusion behaviors is particularly critical to optimize the operation conditions,...

基于改进Random Walk算法的磁共振图像脑组织分割被引量：1
《数据采集与处理》2011年第2期194-199,共6页吴德煌 刘伟 赖凯 范亚 李传富 冯焕清 
国家自然科学基金(60771007)资助项目
在Random Walk算法中,边的权重对算法分割性能有着重要的影响,针对原算法在计算权重时仅使用相邻像素灰度值变化信息的局限性,通过引入图像局部熵,使得权重函数同时反映相邻像素灰度变化信息和图像局部灰度离散度信息,增强算法对目标内...

ON MARKOV CHAINS IN SPACE-TIME RANDOM ENVIRONMENTS被引量：7
《Acta Mathematica Scientia》2009年第1期1-10,共10页胡迪鹤 胡晓予 
Supported by the National Natural Science Foundation of China (10771185 and 10871200)
In Section 1, the authors establish the models of two kinds of Markov chains in space-time random environments (MCSTRE and MCSTRE(+)) with abstract state space. In Section 2, the authors construct a MCSTRE and a MCSTR...
