关联噪声诱导的肿瘤生长过程中的随机共振

Stochastic resonance in the growth of a tumor induced by correlated noises

Wei-Rong Zhong, Yuan-Zhi Shao, Zhen-Hui He

摘要:

在一个同时受加性噪声和乘性噪声驱动的Logistic模型中,乘性噪声将肿瘤的生长规律分为两部分。推导了Fokker-Planck方程,解释了乘性噪声强度对肿瘤细胞生长的影响具有类随机共振特性。适当强度的乘性噪声有利于肿瘤细胞的生长。两类噪声之间的相关性削弱了随机共振的特性。人类的噪音促进了肿瘤细胞的生长。

英文摘要:

Multiplicative noise is found to divide the growth law of tumors into two parts in a logistic model, which is driven by additive and multiplicative noises simultaneously. The Fokker-Planck equation was also derived to explain the fact that the influence of the intensity of multiplicative noise on the growth of tumor cells has a stochastic resonance-like characteristic. An appropriate intensity of multiplicative noise is benefit to the growth of the tumor cells. The correlation between two sorts of noises weakens the stochastic resonance-like characteristic. Homologous noises promote the growth of the tumor cells.
