Big Bird: A global dataset of birds in drone imagery annotated to species level

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Drones are a valuable tool for surveying birds, but manually detecting and identifying birds in drone images is costly. We assembled a diverse dataset of 23 865 images of birds captured with 21 different drones across 11 countries. We labelled 4824 of these images, detailing the location, species, posture category, age category, and sex of 49 990 birds

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

open access: yesSustainable 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 ...

Synthesis of Samarium‐incorporated X‐ray‐sensitive nanoparticles and hydrogels: Diverse applications in radiation monitoring and dynamic information display

open access: yesSmart Molecules, EarlyView.
Sm3+‐doped α‐NaLuF4 and β‐NaLuF4 were synthesized. The X‐ray‐activated persistent luminescence abilities and afterglow properties can be well controlled. Sm3+‐doped β‐NaLuF4 exhibits remarkable afterglow ability. The hexagonal β‐NaLuF4:3%Sm3+‐incorporated hydrogel can be further programmed with other types of hydrogels to enable tunable emission ...

White light emitting molecular logic gates

open access: yesSmart Molecules, EarlyView.
White light emitting smart molecules with Boolean logic computing ability are surveyed. Abstract White light emitting (WLE) materials are of considerable interest with commercial and societal applications in video displays and lighting devices. A characteristic property of WLE materials is the luminescence profile spanning from 380 to 700 nm.
