Cascading bottom‐up effects of invasive alien plants on the parasitoid Aphidius colemani mediated by the aphid host Aphis fabae

open access: yesPest Management Science, EarlyView.
Differences in the suitability of invasive alien plants as hosts drove variations in cascading bottom‐up effects in aphid host and parasitoid performance, potentially influencing top‐down regulation. Abstract BACKGROUND Invasive alien plants (IAP) can threaten biodiversity by disrupting trophic interactions and, consequently, affect agroecosystems by ...

Integrating Image Segmentation and Deep Learning to Improve Radio Frequency Propagation Models

open access: yesInternational 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 ...
