Dynamics of Social Group Competition: Modeling the Decline of Religious Affiliation [作者：Abrams, DM; Yaple, HA; Wiener, RJ,期刊：PHYSICAL REVIEW LETTERS, 页码：88701-88701 , 文章类型： Article，,卷期：2011年107-8] When social groups compete for members, the resulting dynamics may be understandable with mathematical models. We demonstrate that a simple ordinary differential equation (ODE) model is a good fit for religious shift by ... Competition and Cooperation in One-Dimensional Stepping-Stone Models [作者：Korolev, KS; Nelson, DR,期刊：PHYSICAL REVIEW LETTERS, 页码：88103-88103 , 文章类型： Article，,卷期：2011年107-8] Mutualism is a major force driving evolution and sustaining ecosystems.
