Predicting the future dynamics of complex systems remains challenging in scientific research. Traditional methods generally approach this issue by approximating the correlations between predictors (features) and target variables, often empl...
Hierarchical clustering in mean-field coupled Stuart-Landau oscillators [0.03%]
平均场耦合Stuart-Landau振子中的层次聚类现象

Clustered solutions in oscillator networks provide an important insight into how a system might diversify from a synchronous solution into spatiotemporal complex solutions. They can, therefore, form a link between the fully synchronized and...

In this paper, we are devoted to theoretically analyzing the stability of the completely incoherent state in the D-dimensional generalized Kuramoto model within the same one framework, where a completely incoherent state refers to that all ...
Economic collapse under epidemic-induced lockdowns and its prediction: A coupled dynamics approach [0.03%]
疫情封锁下的经济崩溃及其预测:一个耦合动力学方法
