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 ...

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 ...

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 ...
