Revisiting the Growth–Forest Sustainability Nexus in India: The Role of Human Capital, Energy, and Trade

Sustainable Development, EarlyView.
ABSTRACT Understanding whether the interaction between economic activity and forest ecosystems manifests as conflict or synergy is central to designing effective, sustainable development policies. Although the environmental Kuznets curve framework is frequently utilized to explain this relationship, its analytical scope remains limited, as it ...

The association between naloxone distribution, buprenorphine treatment and retention and incident high‐risk opioid prescribing with opioid overdose death in Kentucky, Massachusetts, New York and Ohio, United States: An exploratory community‐level cohort study of data from the HEALing Communities Study

Addiction, EarlyView.
Abstract Aim We evaluated whether community‐level naloxone distribution, medication for opioid use disorder treatment and retention and incident high‐risk opioid prescribing rates were associated with opioid overdose death rates. Design Observational cohort conducted using 2019 to 2023 community‐level data as an exploratory analysis of the HEALing ...

Artificial neural network-based prediction of complete forming limit curves for steel in sheet metal forming

Journal of Alloys and Metallurgical Systems
Forming Limit Curve (FLC) is crucial for predicting material formability and preventing defects in the sheet metal forming industry. Traditionally, FLCs are determined through Nakajima and Marciniak tests, which assess the material's response to various ...

Taxonomic and functional diversity of urban bees of the world

Conservation Biology, EarlyView.
Abstract Bees play a pivotal role in terrestrial environments. Urbanization can affect these organisms and the ecosystem services they provide. However, knowledge of the global diversity of urban bees is limited. Thus, we summarized data on urban bee species identities and occurrences; compared distributions of all bees with those found in urban ...
