Wei Zhang, Christof Schütte • Entropy
(2017)
Many interesting rare events in molecular systems, like ligand association, protein folding or conformational changes, occur on timescales that often are not accessible by direct numerical simulation. Therefore, rare event approximation app...

Yanpeng Zhang, Wenjie Dong, Jing Zhang, Qun Ding • Entropy
(2023)
Most existing chaotic systems have many drawbacks in engineering applications, such as the discontinuous range of chaotic parameters, weak chaotic properties, uneven chaotic sequence outputs, and dynamic degradation. Therefore, based on the...
