Application of the Natural Decomposition Method to Strongly Coupled Partial Differential Equations: The Gray-Scott Model. by Nsingwire, Godwin

“…While this study employed a fixed parameter approach, it also recommends exploring the infinite series solution to provide a more comprehensive understanding of the system's dynamics. Overall, the natural decomposition method proves to be a robust and versatile tool, offering both analytical clarity and computational efficiency in modeling complex chemical and biological systems governed by nonlinear partial differential equations.…”

Optomechanical Backreaction of Quantum Field Processes in Dynamical Casimir Effect by Xie, Yu-Cun, Butera, Salvatore, Hu, Bei-Lok

“…Our findings comply with what is known as the quantum Lenz law, found in cosmological backreaction problems: the backreaction works in the direction of opposing further changes, which means the suppression of particle creation and a slow down of the system dynamics. In conclusion we suggest two related classes of problems of theoretical significance for further investigations.…”
