International Journal of Satellite Communications and Networking, EarlyView.ABSTRACT The integration of low Earth orbit (LEO) satellite constellations with commercial aircraft communication systems presents critical challenges in maintaining continuous connectivity during dynamic flight conditions. Current geostationary satellite systems suffer from high round‐trip latency (>$$ > $$ 500 ms) and inadequate coverage at high ...

Estimating red deer Cervus elaphus population density using drones in a steep and rugged terrain
Wildlife Biology, EarlyView.Precise and accurate information about population density, crucial for wildlife management, is difficult to obtain for elusive species living in dense forests or steep and inaccessible terrain. Using unmanned aerial vehicles (UAVs), we developed a method for obtaining absolute population estimates of ungulates living in steep, rugged, and partly ...

Design of an unmanned, reusable vehicle to de-orbit debris in Earth orbit [PDF]
The space debris problem is becoming more important because as orbital missions increase, the amount of debris increases. It was the design team's objective to present alternative designs and a problem solution for a deorbiting vehicle that will ...

High Voltage, EarlyView.ABSTRACT Power lines in synthetic‐aperture radar (SAR) images are reflected as point signatures, which fluctuate annually in both the azimuth and range directions. A novel framework is proposed in this paper to evaluate the four‐dimensional dynamic status of power line sag using those point signatures in time‐series SAR images.

Integrative Zoology, EarlyView.Climate change and anthropogenic activities drive antagonistic degradation of landscape connectivity for endangered François’ langur (1987–2024), causing 48.8% habitat loss, north‐south fragmentation, and centroid migration (1.2 km/yr). Despite protected areas buffering connectivity, static management fails dynamic priority habitats; we propose ...

Unravelling the evolution of the Frébouge polygenetic cone in Val Ferret (Mont Blanc Massif)
Boreas, EarlyView.Proglacial settings in the Alps are typically polygenetic, often characterized by a complex and discontinuous interplay between glacial, fluvial and gravitational processes. These processes yield high volumes of sediments, which usually exceed their transportation capacity.
