Efficient Wavelength Selection for Limited Near‐Infrared Spectral Data via Genetic Algorithm and Hybrid Regression

Journal of Chemometrics, Volume 39, Issue 3, March 2025.
ABSTRACT Spectral data often contains a large number of variables that are highly correlated. Although Partial Least Squares (PLS) regression is specifically designed to handle issues arising from limited sample sizes, its effectiveness may still diminish in extremely small datasets, making it challenging to construct a calibration model with high ...

Analysis of the First Three Waves of COVID‐19 in West Africa Using an Epidemic Model With Different Modes of Transmission

Complexity, Volume 2025, Issue 1, 2025.
COVID‐19, although now at the endemic stage in numerous regions, is a serious public health challenge. While the virus spreads primarily through direct human‐to‐human contact, it can also be transmitted indirectly through contaminated environments. In this study, we propose a nonlinear epidemic model to analyze the first three waves of COVID‐19 in ...

Next‐Generation Vaccines for Co‐Circulating PEDV and TGEV: Integrating Nucleic Acid Platforms, Mucosal Delivery, and AI–Driven Antigen Design

Transboundary and Emerging Diseases, Volume 2025, Issue 1, 2025.
Porcine epidemic diarrhea virus (PEDV) and transmissible gastroenteritis virus (TGEV) are causative agents of acute enteric diseases in pigs and have a high contagion potential. These coronaviruses (CoVs) impose substantial economic losses on global pork production, particularly affecting lactating piglets where coinfections occur. Although traditional
