A new metaheuristic optimization algorithm based on COVID-19: mathematical model and application to pandemic control

Abstract This paper introduces the COVID-19 optimization algorithm (COA), a novel metaheuristic inspired by the dynamical processes of the SARS-CoV-2 pandemic, including viral transmission, quarantine measures, recovery, and mutation. COA models the search for optimal solutions t...

Advanced olive leaf area prediction using machine learning methods

Abstract Accurate leaf area estimation is essential for understanding olive tree physiology, productivity, and stress adaptationThis study developed and evaluated machine learning models for non-destructive olive leaf area prediction using linear measurements (length and width) f...

Generation Mean Analysis of Gene Action for Photosystem II Fluorescence Parameters in Two Bread Wheat Crosses

Chlorophyll fluorescence parameters are sensitive indicators of photosystem II (PSII) functionality and overall photosynthetic performance; however, their genetic architecture in wheat remains poorly understood. This study aimed to elucidate the gene action governing chlorophyll...

Comparing Hair Cortisol, DHEA, and Cortisol-to-DHEA Ratios from Various Body Sites in Anatolian Shelter Dogs

Hair-based biomarkers offer a non-invasive window into chronic stress physiology, yet the influence of sampling body site on hair cortisol, dehydroepiandrosterone (DHEA), and their molar ratio has not been systematically characterized in domestic dogs. This study compared these t...

Shelf-life extension of refrigerated rainbow trout fillets using chitosan/gelatin bilayer film enriched with ZnO nanoparticles and tea polyphenols

Abstract This study aimed to evaluate the effect of a chitosan–gelatin film incorporated with zinc oxide nanoparticles (ZnO NPs) and tea polyphenols (TPs) on the bacterial count, physicochemical properties, and sensory attributes of rainbow trout during refrigerated storage. To a...
