混沌波作为通用模式发生器

Chaotic waves serve as universal pattern generators

Sergey A. Vakulenko, Ivan Sudakow, John Reinitz, Dmitry Grigoriev

摘要:

激发介质是描述支持波传播的物理、化学和生物系统的流行模型。在这封信中,我们表明,在波前的介质状态的时间演化可以确定复杂的混沌吸引子。波前动力学可以通过初始数据的选择来控制。在此基础上,我们表明,有一个机械化学模拟的通用图灵机的形态发生问题。也就是说,一个固定的机械化学系统可以根据其输入(初始数据)产生任何规定的细胞模式。这种通用机制使用基本的物理效应:自发对称性破缺,形成许多界面(扭结),通过快速扩散试剂进行非局部相互作用。这种互动造成了混乱。我们提出的算法,使我们能够获得规定的目标细胞模式。

英文摘要:

Excitable media are prevalent models for describing physical, chemical, and biological systems which support wave propagation. In this letter, we show that the time evolution of the medium state at the wave fronts can be determined by complicated chaotic attractors. Wave front dynamics can be controlled by initial data choice. Building on this groundwork, we show that there is a mechano-chemical analog of the Universal Turing machine for morphogenesis problems. Namely, a fixed mechano-chemical system can produce any prescribed cell pattern depending on its input (initial data). This universal mechanism uses fundamental physical effects: spontaneous symmetry breaking with formation of many interfaces (kinks), which interact non-locally via a fast diffusing reagent. This interaction creates chaos. We present algorithms allowing us to obtain a prescribed target cell pattern.
