An interdisciplinary review of the interplay of conflict, socio‐economic factors, and land cover and vegetation dynamics in Colombia

PLANTS, PEOPLE, PLANET, EarlyView.
Colombia's forests play a crucial role in preserving biodiversity and mitigating climate change, but they are currently facing severe degradation, particularly after the 2016 Peace Agreement. Our literature review highlights a growing research interest in this topic and demonstrates how interdisciplinary approaches combining diverse methods can enhance

Joint power control and user grouping mechanism for efficient uplink non‐orthogonal multiple access‐based 5G communication: Utilising the Lèvy‐flight firefly algorithm

IET Networks, EarlyView., 2023
We utilise a metaheuristic optimisation method, inspired by nature, called the Lévy‐flight firefly algorithm (LFA), to tackle the power regulation and user grouping in the NOMA systems. Abstract The non‐orthogonal multiple access strategies have shown promise to boost fifth generation and sixth generation wireless networks' spectral efficiency and ...

Pesticide exposure of operators during mixing and loading a drone: towards a stratified exposure assessment

Pest Management Science, EarlyView.
Operators are exposed to concentrated formulation during mixing of pesticide into the nurse tank and to an in‐use dilution during loading the drone; stratification of exposure for mixing and loading would inform the exposure assessment approach by applying the appropriate dermal absorption considerations.
