Achieving optimal GaN/SiC interfacial thermal conductance via ultrathin alloy interlayers for high-power device cooling
Efficient heat dissipation across GaN/SiC interfaces is critical for the reliability of high-power devices, yet their interfacial thermal transport behavior remains insufficiently understood. Here, using a high-fidelity machine-learning interatomic potential, we perform systematic nonequilibrium molecular dynamics simulations to quantify and engineer the interfacial thermal conductance (ITC) of device-relevant SiC/GaN heterostructures. The results show that Al-rich […]

In dual-UAV scenarios, simulation optimization results closely align with the theoretical optimal solutions derived from logarithmic spiral geometry, showing […]
Explosives Found Near Crashed Ukrainian Drone in Lithuania, Officials Say
Explosives were discovered on Monday near the wreckage of a suspected Ukrainian military drone that crashed in Lithuania. The Lithuanian police stated that the materials are too dangerous to remove, so they will be disposed of by detonation at the site. The drone entered Lithuania without being detected and crashed in Samane, located 40 km […]
Edge-Friendly UAV Wildfire Smoke and Flame Detection Using Transfer Learning-Enhanced Lightweight Deep Learning Models
Edge computing on unmanned aerial vehicles (UAVs) enables low-latency wildfire monitoring by performing visual inference onboard; however, practical deployment is constrained by limited labeled data and resource budgets that often preclude reliance on large GPU servers. This work investigates transfer learning (TL) for UAV-based wildfire smoke and flame detection and evaluates its impact on both […]

Control-Certified Wireless Resource Allocation for Digital-Twin-Enabled UAV Swarms
Wireless resource allocation in digital-twin-enabled unmanned aerial vehicle (UAV) swarms must be both network-feasible and certifiably safe for closed-loop control. Existing packet-level or scalar-priority schedulers cannot meaningfully compare heterogeneous multi-hop actions that differ simultaneously in route, retransmission depth, blocklength, bidirectional delay, delivery probability, and TDMA slot cost. This paper introduces a certificate-guided resource allocation framework […]
A 3D UAV Path Planning Algorithm Based on Bidirectional RRT* with Adaptive Directional Sampling and Cooperative Dual-Tree Expansion
UAV path planning in complex three-dimensional obstacle environments requires a balance between search efficiency and flight feasibility. However, existing RRT*-based methods often fail to satisfy this requirement, as their random sampling lacks directional guidance and makes limited use of environmental information. To this end, this paper proposes an environment-aware cooperative bidirectional RRT* algorithm (EAC-Bi-RRT*). In […]
