The emergence of collective motion such as in fish schools,mammal herds,and insect swarms is a ubiquitous self-organization phenomenon.Such collective behavior plays an important role in a range of problems,such as spreading of deceases in animal or fish groups.Current models have provided a qualitative understanding of collective motion,but progress in quantitative modeling in hindered by the lack of experimental data.Here we examine a model microscopic system,where we are able to measure simultaneously the positions,velocities,and orientations of up to a thousand bacteria in a colony.

在分子动力学模拟的基础上,我们分析了受限于纳米管道呈现一维水链的水分子,其偶极方向的的不对称性导致水分子沿纳米管道运动的不对称性.我们还建立了简化模型,基于棘轮效应来分析这个不对称流动的物理背景,并说明这样的(自发)不对称流动并不违反热力学第二定律.

在极化分子电流变液中,剪切应力会随着电场强度、交流电场频率、剪切速率而变化;同样,在一定的电场强度、频率、剪切速率下,电流变液中会出现剪切带,且剪切带会随外界条件而变化,乃至消失.

蛋白质是生命体中重要的功能大分子.蛋白质的功能的实现一方面依赖于其折叠成特定的三维结构,另一方面也需要保持其天然态构象的动态性.然而蛋白质如何通过其序列的进化来获得这两方面的平衡的,还是一个未知的问题.
