The Journal of Wildlife Management, EarlyView.Fine‐scale population variables better explain roadkill patterns in natterjack toads (Epidalea calamita) than habitat proxies, with mortality driven mainly by local abundance, reduced by roadside embankments, and decreasing as the season advanced. Despite high roadkills, population viability analyses indicate no immediate extinction risk under current ...

Integrating Image Segmentation and Deep Learning to Improve Radio Frequency Propagation Models
International Journal of Satellite Communications and Networking, EarlyView.ABSTRACT This paper proposes a multi‐sensor approach to improve radio frequency (RF) propagation models, which play a key role in the rapidly expanding field of connected vehicle technology. Focusing on the 1‐ to 20‐GHz frequency range, which is critical for both satellite‐to‐vehicle and base station‐to‐vehicle communications, our study introduces a ...

Analysis of the mechanism and effects of advanced pipes support in roadways
Scientific ReportsWith the increasing depth of coal mining, the deformation and instability of high-stress soft rock roadways have become critical challenges in mining engineering. Although various support technologies have been applied to deep soft rock roadways, research on the support mechanism and mechanical effects of advanced pipes remains limited.
