论文摘要
生物系统中的主动夜毒模型通常需要由微观水平涉及的流体动力以及系统的粘弹性产生的复杂性。在这里，我们表明，基于活动和聚合物颗粒的时间对齐的最小，独立于空间的模型为预测和研究其在动态系统框架内的耦合动力学提供了途径。特别是，我们使用分析和数值方法检查了这种简单的模型如何在活动驱动的粘弹性剪切流中显示自我维持的振荡。
Models of active nematics in biological systems normally require complexity arising from the hydrodynamics involved at the microscopic level as well as the viscoelastic nature of the system. Here we show that a minimal, space-independent, model based on the temporal alignment of active and polymeric particles provides an avenue to predict and study their coupled dynamics within the framework of dynamical systems. In particular, we examine, using analytical and numerical methods, how such a simple model can display self-sustained oscillations in an activity-driven viscoelastic shear flow.
