Deep learning‐based super‐resolution reconstruction and improved YOLOv9 for efficient benthos detection: a case study at Lake Hamana, Japan

Remote Sensing in Ecology and Conservation, EarlyView.
This study presents a UAV‐based framework that integrates deep learning‐based super‐resolution reconstruction and an enhanced YOLO detector to improve centimetre‐scale benthic organism monitoring. Using hermit crabs in Lake Hamana, a coastal lagoon in Japan, as a case study, the method substantially enhanced small‐object detection performance ...

CLEAR Interference Cancellation in a Wideband Dual‐Channel Receiver for Independent Satellite Multi‐Connectivity Links

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT In this paper, the correlation learning estimation and adaptive reduction (CLEAR) of interference, an adaptive, blind and transparent interference compensation method applied in a wideband dual‐channel receiver, is studied for a pair of independent satellite multi‐connectivity links, using the same carrier frequency and signal bandwidth in use

Contribution of the Baobab Value Chain to Equitable Rural Livelihoods and Poverty Alleviation in Ghana

Sustainable Development, EarlyView.
ABSTRACT Non‐timber forest products (NTFPs) are central to income diversification and livelihood resilience in Sub‐Saharan Africa. However, the welfare implications of baobab commercialisation remain underexplored. This study addresses this gap by analysing the contribution of the baobab value chain to household income, poverty reduction, and income ...

How Tariffs Shape Trade‐Embodied Emissions in the European Union: Sectoral Heterogeneity in Final Demand

Sustainable Development, EarlyView.
ABSTRACT This paper examines the environmental implications of tariffs on greenhouse gas emissions embodied in extra‐European Union imports consumed by domestic final demand in the EU. Using a multidimensional country‐sector‐year framework, the study investigates whether tariff changes are associated with variations in trade‐embodied emissions and ...

Additive Manufacturing of Hot‐Work Tool Steel by In Situ Alloying Using Laser Powder Bed Fusion and Directed Energy Deposition—Strategies to Improve Chemical Homogeneity

steel research international, EarlyView.
To support future alloy development a powder mixture is processed by laser additive manufacturing. The powder mixture containing Mo‐ and W‐rich tracers is processed by powder bed fusion using single and double laser exposure and by directed energy deposition which provides drastically enlarged melt pools.
