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 ...

Directive Antenna Clutter Loss in Slant Paths
International Journal of Satellite Communications and Networking, EarlyView.ABSTRACT This paper investigates the development of a clutter loss model specifically for slant paths involving directive antennas. Conventionally, clutter loss is characterized by using isotropic antennas to facilitate standard link budget calculations via single antenna gain values.

Hot Injection Synthesis of Ultrathin Bi2Se3 Nanosheets With Controllable Dimensions
Small Methods, EarlyView.Graphic of hot‐injection method for synthesizing Bi2Se3${\rm Bi}_2{\rm Se}_3$ nanoplatelets of controlled shape, thickness, and lateral size. The ultra‐thin regime is achievable, which is interesting for studying topological phase transitions. ABSTRACT In this work, a synthesis method for colloidal nanoplatelets (NPLs) of the topological insulator ...

Wildlife Biology, EarlyView.Resource managers require accurate estimates of large herbivore abundance and demography to maintain ecological integrity. Common methods to count these species, including observations from low altitude helicopter flights, may conflict with other protected area management objectives and struggle to produce precise estimates for more cryptic species. To

MultiRobot Motion Planning Based on Diffusion and Time–Space Path Planning
Artificial Intelligence for Engineering, EarlyView.This diffusion‐based framework for multirobot motion planning reuses a pretrained single‐robot Motion Planning Diffusion model, employing an alternating trajectory generation scheme guided by inter‐robot collision costs, resulting in coordinated planning without additional multi‐robot training.
