The rheology of biological tissue plays an important role in many processes, from organ
formation to cancer invasion. Here, we use a multiphase field model of motile cells to …

The drag force on a spherical intruder in dense granular shear flows is studied using
discrete element method simulations. Three regimes of the intruder dynamics are observed …

在行星探索过程中涉及探测器在星壤上着陆, 运动以及收集, 存储某些样本材料等问题,
因此需要建立探测机器人在沙土上运动的动力学模型, 从而优化其系统构型. 近年来 …

The equation of state for an ideal gas is simple, which is P= nk BT. In the case of imperfect
gases where mutual interactions among the constituents are important, pressure P can be …

The Brazil nut effect (BNE) is a counter-intuitive process of segregation of a large object
inside a vibrated granular medium (GM), which has been studied widely by subjecting GMs …

Granular matter is a disordered system composed of a large number of particles, which
appears as a complex physical phenomenon under external excitation. To study the …

In the process of planetary exploration, it involves the landing and movement of the probe on
the earth, as well as the collection, storage and return of some sample materials. Therefore …
