反应扩散系统中的分子离散性产生了在连续极限中看不到的稳态
Molecular Discreteness in Reaction-Diffusion Systems Yields Steady States Not Seen in the Continuum Limit
摘要:
研究了反应扩散系统中分子空间离散性的影响。研究发现,所谓的仓本长度内的离散性可以导致分子的局部化,从而产生在连续情况下不存在的新的稳态。这些新的状态进行了理论分析,加速局域化反应的不动点,一种方法,被证实是在良好的协议与随机粒子模拟。这种离散诱导状态的生物细胞内过程的相关性进行了讨论。
英文摘要:
We investigate the effects of spatial discreteness of molecules in reaction-diffusion systems. It is found that discreteness within the so called Kuramoto length can lead to a localization of molecules, resulting in novel steady states that do not exist in the continuous case. These novel states are analyzed theoretically as the fixed points of accelerated localized reactions, an approach that was verified to be in good agreement with stochastic particle simulations. The relevance of this discreteness-induced state to biological intracellular processes is discussed.
