2024年8月23日，我院周艳课题组和生研院朱永群课题组联合在Cell Research杂志在线发表了题为 “Structural basis of the bacterial flagellar motor rotational switching”的研究论文，通过构建激活型趋化因子蛋白CheY突变体，纯化来源于病原菌沙门氏菌（Salmonella Typhimurium）的内源性的、...
模糊n-cell数近似大于等于关系的性质
模糊n-cell数 近似大于等于 近似大于 水平收敛

2022/3/28
研究了模糊n-cell数近似大于等于关系、近似大于关系在水平收敛下的变化，与通常实数序列性质类似，近似大于等于关系在水平收敛下能保持不变，近似大于关系在水平收敛下无法保持。但是与通常实数列极限具有保号性不一样的是，水平收敛的模糊n-cell数序列关于近似大于关系的保号性不成立。
Exponential decay for the fragmentation or cell-division equation
Exponential decay fragmentation cell-division equation

2012/4/18
A host-parasite model is considered for a population of cells that can be of two types, A or B, and exhibits unilateral reproduction: while a B-cell always splits into two cells of the same type, the ...
