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…
Network-Based Multi-Layer Model Using Machine Learning for Optimal Vaccine Prioritization in Heterogeneous Populations
Mordecai Opoku Ohemeng, Bernard Asamoah Afful
This work advances epidemic control beyond traditional mass vaccination models by integrating population heterogeneity, network structure, and machine-learning-based decision polic…
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…
Intermittent precipitation and spatial Allee effects drive irregular vegetation patterns in semiarid ecosystems
Àlex Giménez-Romero, Bernard A. Afful, Priscilla E. Greenwood +2
Vegetation in semi-arid ecosystems frequently organizes into spatially heterogeneous mosaics that regulate ecosystem functioning, productivity, and resilience. These patterns arise…
