模拟社会时差的模型中的同步和吸引子
Synchronization and attractors in a model simulating social jetlag
摘要:
已经做了很多工作来研究社会时差,这是由于暴露于不同的光输入而导致的生物钟和社会议程之间的不一致,其导致几个健康问题。为了研究同步和吸引子,由于一系列的光输入,我们引入了一个扩展的模型,以前用于描述由一个单一的光输入的变化所造成的时差。与光输入的同步对系统的控制参数和光输入周期敏感。根据参数设置,观察到的同步是与一个或另一个连续的光输入。大多数的解决方案具有光输入的周期。然而,对于某些参数,我们也观察到更高的周期,混沌的解决方案,和双稳态。
英文摘要:
Much work has been done to investigate social jetlag, a misalignment between the biological clock and the social agenda caused by exposition to different light inputs, that causes several health issues. To investigate synchronization and attractors due to a sequence of light inputs, we introduce an extension of a model, previously used to describe jetlag caused by a single change in the light input. The synchronization to the light input is sensitive to the control parameters of the system and to the light input periods. Depending on the parameter set, the observed synchronization is with one or another successive light input. Most of the solutions have the period of a light input. However, for some parameters, we also observed higher period, chaotic solutions, and bistability.
