Characterization of Healthy and Faulty Networks using Structured Transferometry Residuals

Ameer Ahmadie, Virginie Degardin, Vincent Cocquempot

This paper presents the characterization of healthy and faulty situations in Y-shaped communication networks using a transferometry-based diagnostic method. The study focuses on soft faults, defined as small degradations that do not significantly impact data or power transmission in networks....

Microfabricated vapor cells with tunable buffer gas mixtures using laser-actuated break-seal reservoirs

Clément Carlé, Gabriel Faure, Shervin Keshavarzi, Quentin Tanguy, Emmanuel Klinger, Vincent Maurice, Rodolphe Boudot, Nicolas Passilly

Microfabricated cells are the core component of a wide variety of chip-scale atomic devices, such as clocks or magnetometers [1]. In those instruments, the cell is generally filled with a pressure of buffer gas. The presence of buffer gas reduces the atom-wall collision rate, enhances the atomic...

Impact of iodine-induced nonplanarity on the vibrational and electronic properties of a triphenylene derivative: A combined experimental and DFT study

Ahmed Hewail, David Guérin, Christophe Krzeminski, Eric Faulques, Nataliya Kalashnyk

We present a molecular study combining Raman, infrared, and UV–visible absorption spectroscopy with density functional theory (DFT) calculations to investigate triphenylene and its iodinated derivative, 1,5,9-triiodotriphenylene. The results provide a detailed comparison of their vibrational and...

Electrostatic force regularization for neural structured pruning

Abdesselam Ferdi, Abdelmalik Taleb-Ahmed, Amir Nakib, Youcef Ferdi

The demand for deploying deep convolutional neural networks (DCNNs) on resource-constrained devices for real-time applications remains substantial. However, existing state-of-the-art structured pruning methods often involve intricate implementations, require modifications to the original network...

Exploiting the insulator–metal transition of VO2 in photocatalytic methane conversion

My Nghe Tran, Duc Manh Nguyen, Matthieu Kpessu Ahounou, Ernesto de la Torre Miranda, Melissa Alzate Banguero, David Troadec, Christophe Coinon, Ahmed Addad, Karima Ben Tayeb, Alexandre Boulle, Pascale Diener, David Mele, Louis Thomas, Xavier Wallart, Lionel Aigouy, Alexandre Zimmers, Aurelian Crunteanu, Vitaly Ordomsky, Bruno Grandidier

Upon illumination, photocatalysts generate charge carriers for redox reactions, but their efficiency is often limited by carrier recombination and poor minority-carrier diffusion, despite many existing junction engineering strategies. Here we exploit the insulator–metal transition in VO2 to produce...

AlGaN Back-Barrier Integration for Trap Reduction in Buffer-Free GaN HEMTs on SiC

François Grandpierron, Elodie Carneiro, Lyes Ben-Hammou, Anders Lundskog, Jui-Che Chang, Jr-Tai Chen, Farid Medjdoub

This work investigates the impact of incorporating an AlGaN back barrier (BB) in buffer-free AlGaN/GaN high electron mobility transistors (HEMTs) on SiC. Both devices use an AlN nucleation layer (NL) for vertical isolation, while the modified structure introduces an Al0.2Ga0.8N BB beneath the GaN...
