Terminaison mechanisms of Turing patterns in growing systems

Gabriel Morgado, Laurence Signon, Bogdan Nowakowski, Annie Lemarchand

摘要:

在一个不断增长的系统中的图灵型的周期性空间结构的终止的问题是解决在化学工程的角度和仿生的方法。的稳定性和波长的结构上的动力学参数的影响进行了分析研究,并用于提出实验条件的图灵图案停止自己的波长减小。所提出的机制是成功地检查由数值积分的方程的动力学的激活剂和抑制剂。我们的结论是,控制抑制剂注入系统的速率的储层的浓度的局部增加可以用于实现图灵模式的适当终止。

英文摘要:

The question of the termination of a periodic spatial structure of Turing type in a growing system is addressed in a chemical engineering perspective and a biomimetic approach. The effects of the dynamical parameters on the stability and the wavelength of the structure are analytically studied and used to propose experimental conditions for which a Turing pattern stops by itself with a decreasing wavelength. The proposed mechanism is successfully checked by the numerical integration of the equations governing the dynamics of the activator and the inhibitor. We conclude that a local increase of the concentration of the reservoir which controls the injection rate of the inhibitor into the system can be used to achieve the appropriate termination of a Turing pattern.
