Regularity underlies erratic population abundances in marine ecosystems
Jie Sun, Sean P. Cornelius, John Janssen +2
The abundance of a species' population in an ecosystem is rarely stationary, often exhibiting large fluctuations over time. Using historical data on marine species, we show that th…
Detecting structural breaks in seasonal time series by regularized optimization
Bing Wang, Jie Sun, Adilson E. Motter
Real-world systems are often complex, dynamic, and nonlinear. Understanding the dynamics of a system from its observed time series is key to the prediction and control of the syste…
Causation Entropy Identifies Indirect Influences, Dominance of Neighbors and Anticipatory Couplings
Jie Sun, Erik M. Bollt
Inference of causality is central in nonlinear time series analysis and science in general. A popular approach to infer causality between two processes is to measure the informatio…
An integral representation for the product of two parabolic cylinder functions having unrelated arguments
M. L. Glasser
An integral representation is provided for the parabolic cylinder function product where and are unrelated. A few simple consequences are given in t…
