A Tensor-Based Modulation Scheme with Hybrid Optimization for Unsourced Random Access

Ala Baccar, Alexis Decurninge, Sofiane Kharbech, Rima Khouja, Eric Pierre Simon, Joumana Farah

<div><p>This paper extends the idea of tensor-based modulation (TBM) for unsourced random access by introducing a new small sub-constellation, enabling a hybrid continuous-discrete optimization approach on the tensor factors. This approach enhances the detection process and extends the…

Effect of High Temperature RF Stress on the Trapping Behavior of Carbon Doped AlN/GaN/AlGaN HEMTs

Lyes Ben-Hammou, François Grandpierron, Elodie Carneiro, Katir Harrouche, Etienne Okada, Gilles Patriarche, Farid Medjdoub

This study investigates the impact of short-term hightemperature operating life (HTOL) reliability testing on the trapping behavior and power performance of carbon-doped AlN/GaN/AlGaN High Electron Mobility Transistors (HEMTs). HTOL stress can lead to significant degradation in key performance…

Broadband and omnidirectional attenuation of bulk waves in transversely isotropic soil by cross-like metamaterials

Runcheng Cai, Yabin Jin, Yan Pennec, Bahram Djafari-Rouhani, Timon Rabczuk, Xiaoying Zhuang

Metamaterials with bandgap properties have been widely studied and applied in the attenuation of surface and bulk waves propagating in the soil. However, most of the studies consider soil as the isotropic medium and ignore the general anisotropy property from the practical point of view. In this…

Electroisomerization blinking of an azobenzene derivative molecule

Sylvie Godey, Hugo Therssen, David Guérin, Thierry Melin, Stéphane Lenfant

Abstract We report here the reversibility and bistability of the switching behavior in an azobenzene derivative induced by the bias applied by a Scanning-Tunneling Microscopy (STM) tip, at low temperature and in ultra-high vacuum environment. This cis-to-trans and trans-to-cis switching were…
