Cell monolayers and epithelial tissues display slow relaxation dynamics during the reversible transition between mesenchymal cells, a phenomenon directly relevant to embryogenesis, tumor metastases, wound healing. In active persistent motion induces collective that significantly influence behavior. To better understand role of persistence in cell relaxations, we perform extensive simulations employ cage-relative measures address previously overlooked system size effects model cells. We...
The migration of active particles in slowly moving, crowded, and heterogeneous media is fundamental to various biological processes technological applications. In this study, we numerically investigate the dynamics a single particle multicomponent medium composed mixtures rigid flexible rings. We observe nonmonotonic dependence diffusivity on relative fraction rings, leading identification an optimal composition for enhanced diffusion. This long-time diffusion, resulting from different...
Abstract For the asymmetric D-shaped fragmentation warhead with high charging coefficient and space efficiency, we simulate driving process of fragments under typical eccentric initiation by using fluid-structure interaction algorithm, obtained change rule fragment velocity radial distribution central angel, thickness material upper end cap. The results numerical simulation show that increases gradually from reverse to forward direction, in direction about 10% single-point compared...
Abstract The energy distribution characteristics are the key parameters for analysing of cylindrical cased charge and improving damage efficiency warhead. To investigate initial velocities from a detonated at point on axis, flash X-ray radiography system was used to test end caps, influence axial position detonation further studied by simulation. experimental results show that when thickness cap is equal casing ratio length diameter 3, velocity front 0.53 times rear cap. simulation affected...
