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

open access: yesIET 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 ...

Mental health benefits of urban green—A systematic review and meta‐analysis of 56 pre‐post control experiments

open access: yesPeople and Nature, EarlyView.
Abstract Background. Fostering healthy urban living conditions is a critical public health objective. One efficient approach lies in the contact to nature, as numerous studies have shown that urban and peri‐urban natural elements both indoors and outdoors carry a large potential in buffering typical urban threats to mental health.

Views from the hill: Deer stalkers' perspectives on land‐use change in the Scottish Highlands

open access: yesPeople and Nature, EarlyView.
Abstract Land‐use and wildlife management are changing globally as part of efforts to address contemporary environmental challenges. In the Scottish Highlands, the hunting—or ‘stalking’—of deer has entered a period of considerable flux primarily because of national policy changes to mitigate climate change and biodiversity loss.
