摘要
通过一个基本的双变量模型,研究了共同噪音对于生物钟的集体行为的积极作用。发现共同噪音可以在2个非耦合体系的近分叉点稳态区诱导出同步的振荡。另外,内噪音对这种共同噪音诱导的同步振荡有消极的作用,但是振荡的同步性并没有被内噪音明显的降低,说明这种振荡对内噪音具有鲁棒性。
The effect of common noise on the collective behavior of systems was studied with an elementary circadian clock model. It is shown that common noise could induce synchronous oscillations in two uncoupled non-identical systems for the parameters which produce a stable steady state in the deterministic system. In addition, the synchronicity of common noise-induced oscillations is suppressed by the internal noise. However, the synchronicity does not remarkably decrease during a wide range of internal noise intensity, demonstrating the robustness of common noise-induced synchronous oscillations to internal noise.
