Fast Aerodynamic Prediction of Airfoil with Trailing Edge Flap Based on Multi-Task Deep Learning

Aerospace
Conventional methods for solving Navier–Stokes (NS) equations to analyze flow fields and aerodynamic forces of airfoils with trailing edge flaps (TEFs) are known for their significant time cost.

Global distribution of aquatic animal telemetry effort reveals geographic biases and opportunities for more inclusive tracking studies

Conservation Science and Practice, EarlyView.
Despite broad global distribution of aquatic telemetry studies, important biogeographic regions remain poorly investigated. The most important variables correlated with the distribution of telemetry studies were political stability, conservation funding, number of scientific documents, and English as a first language.

Limited elephant impacts on baobabs despite increasing elephant densities in a newly established protected area

Conservation Science and Practice, EarlyView.
Researchers combined aerial and ground surveys to map baobab distribution and assess elephant herbivory impacts on baobabs across Karingani Game Reserve, Mozambique. Researchers found that aerial surveys were an effective tool for mapping baobabs and that baobabs were more likely to occur closer to permanent water, at lower elevations, and in areas ...

Informing elephant management through demographic snapshots

Conservation Science and Practice, EarlyView.
Understanding demography is vital for managing species successfully; however, for elephants, traditional surveys are both costly and labor‐intensive. This study presents a cost‐effective method for estimating age structures of savannah elephants in southern Africa, revealing how water provisioning, density dependence, and fertility control influence ...
