Seasonally dry tropical woodlands are vital for climate change mitigation, yet their full potential in carbon storage remains poorly understood. This is largely due to the lack of species-specific allometric models tailored to these ecosystems. To address this knowledge gap, this study aimed to develop species-specific biomass allometric equations (BAEs) for accurately estimating both above- and below-ground biomass of Colophospermum mopane (J.

To address the challenges of high computational complexity and poor real-time performance in binocular vision-based Unmanned Aerial Vehicle (UAV) formation flight, this paper introduces a UAV localization algorithm based on a lightweight object detection model. Firstly, we optimized the YOLOv5s model using lightweight design principles, resulting in Yolo-SGN. This model achieves a 65.

Traditional agricultural activities and rural livelihoods in Morocco's High Atlas Mountains are rapidly changing. This is triggered by increasing rural-urban interactions and new livelihood opportunities in cities. A typical example is the oasis of Tizi N'Oucheg in the country's High Atlas Mountains, which over centuries was largely self-sufficient in food grain and livestock production.

Background: As the UK COVID-19 vaccination programme progressed, greater emphasis was placed on the implementation of localized targeted vaccination activities to address inequalities in vaccination coverage. This study examines one UK region's approach to the delivery of targeted vaccination activities and identifies key factors influencing implementation.
Methods: Qualitative interviews were conducted with a purposive sample of key individuals involved in vaccination delivery across Greater Manchester (GM).

Objectives: Characterise US residents' exposure to restrictions on sales of flavoured electronic nicotine delivery system (ENDS), cigars and menthol cigarettes across states and time, and assess correlations between these policies.
Methods: From 2022 to 2024, we compiled flavour policy locations from advocacy groups and online searches, located corresponding legal texts and reviewed these to identify policy details, including effective dates. Using census data, we calculated the proportion of state residents covered by each policy quarterly from 2009 to 2024 and estimated correlations between them and cigarette taxes.
