Insights From the Alphasat Aldo Paraboni Experiment at Tito Scalo and Spino d'Adda: Characterizing Scintillation and Rain Attenuation at Ka‐ and Q‐Band Frequencies

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT We present experimental results on the relationship between rain attenuation and simultaneous scintillation during rain events, based on beacon signal measurements at 19.7 (Ka‐band) and 39.4 GHz (Q‐band) from the geosynchronous Alphasat satellite (25° E), received at two Italian ground stations, Spino d'Adda (42.1° slant path) and Tito Scalo ...

YOLO‐GDCNN: Real‐Time Operating Point Detection for Live Working Robots in the Power Industry

High Voltage, EarlyView.
ABSTRACT In the power industry maintenance, the capability of live working robots to detect and operate with power components in real time is paramount. This paper proposes a cascaded detection framework for real‐time detection of live working operation points, named YOLO‐GDCNN. The framework consists of two parts.

Wood anatomical trait correlations with hydraulic efficiency and safety in an aseasonal wet tropical forest

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Xylem anatomy underpins the capacity of trees to transport water while avoiding hydraulic failure, shaping species performance and resilience to climate change. However, the specific ways anatomical traits underpin hydraulic trade‐offs in tropical forests remain debated.

Leukocyte profiles reveal sex and age differences in immune investment in a polygynous bat

Journal of Animal Ecology, EarlyView.
Analysis of over 500 blood cell profiles, including repeat samples over four years, reveals that male bats from a long‐lived species with a polygynous mating system invest more in innate than adaptive immunity. Investment in innate immunity increases with age, as estimated by a DNA methylation clock and mark‐recapture data.

Enter Salmon: Trophic risk mediates riverine barrier‐crossing behaviours of parr

Journal of Animal Ecology, EarlyView.
This study provides evidence that artificial riverine barriers alter juvenile Atlantic salmon behaviour in a context‐dependent manner, with predator presence further restricting movement and barrier interactions. By addressing the overlooked impacts of barriers on river‐resident parr stages, our findings contribute to a better understanding of ...
