Device-level co-integration of direct liquid cooling in GaN-on-SiC RF HEMTs
Gallium nitride on silicon carbide high electron mobility transistors are key enabling devices for high power radio frequency systems. Their performance and reliability are increasingly constrained by self-heating under high power density operation. While silicon carbide substrates provide favorable thermal conductivity, continued scaling toward higher output power intensifies junction heating and exacerbates electro thermal coupling […]

Research Progress on Boron-Modified Phenolic Resin Ablation-Resistant Composites
Boron-modified phenolic resin composites are critical aerospace thermal protection materials due to their ability to form boron-containing ceramic layers during ablation, which provides exceptional ablation resistance. This article systematically reviews recent research progress on boron-modified phenolic resin ablation-resistant composites from two primary design perspectives. Firstly, from the perspective of the resin matrix level, strategies for […]
Design and Experimental Validation of a High-Precision Pressure Regulation Unit for Cold-Gas Micro-Propulsion
The next generation of space-based gravitational wave observatories, such as LISA, TianQin, and Taiji, requires ultra-precise drag-free control and therefore micro-propulsion systems with thrust noise below 0.1μN/√Hz. This paper presents the design and experimental validation of a high-precision pressure regulation unit (PRU) for cold-gas micro-propulsion, guided by a requirement-driven analysis of pressure-induced thrust-noise sensitivity. A first-order […]

Stable Agentic Control: Tool-Mediated LLM Architecture for Autonomous Cyber Defense
Agentic systems involved in high-stake decision-making under adversarial pressure need formal guarantees not offered by existing approaches. Motivated by the operational needs of security operations centers (SOCs) that must configure endpoint detection and response (EDR) policies under adversarial pressure, we present a tool-mediated architecture: LLM agents use deterministic tools (Stackelberg best-response, Bayesian observer updates, attack-graph […]
Orion 26 : L’armée de Terre a eu recours une capacité de renseignement spatial fournie par le finlandais ICEYE
Si elles bénéficient de renseignements d’origine image [ROIM] fournis par les trois satellites de la constellation CSO [Composante Spatiale Optique], les forces françaises ne disposent pas, en propre, de capacités en matière d’imagerie radar, dont l’un des intérêts est de s’affranchir des conditions météorologiques quand il s’agit d’observer les mouvements de l’adversaire. Pour y remédier, […]
