Hybrid SINDy-EnKF in Learning Chikungunya Dynamics from Incomplete, Noisy or Partially Observed Data
Bernard Asamoah Afful, Changhong Mou, Luis Gordillo
Current mechanistic models for the transmission dynamics of the Chikungunya virus (CHIKV) rely on uncertain parameters or partially observed data. This limitation challenges the us…
The Curse of Black Sigatoka: A Backward Bifurcation Perspective
Bernard Asamoah Afful, Luis F. Gordillo
Black Sigatoka disease (BSD), also known as black leaf streak disease, is an airborne fungal infection caused by \textit{Pseudocercospora fijiensis} that severely impacts global ba…
Stability of steady state solutions in a predator-prey model with density-dependent diffusion
Leoncio Rodriguez Quinones, Luis F. Gordillo
In this note we present a study of the solutions associated to a particular spatial extension of the Rosenzweig-MacArthur model for predator and prey. The analysis presented here s…
The effects of simple density-dependent prey diffusion and refuge in a predator-prey system
Leoncio Rodriguez Quinones, Jia Zhao, Luis Gordillo
We study a spatial (two-dimensional) Rosenzweig-MacArthur model under the following assumptions: prey movement follows a nonlinear diffusion, preys have a refuge zone (…
