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, Andrei Mursa, 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...

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...

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...

Experimental and DFT study of the structural, electronic, and thermoelectrical properties of Li3xLa2/3-xTiO3 (x = 0.125) ceramic leads free for battery applications

Hicham Kacimi-Naciri, Meriem Ben Zennou, Assia Mabrouk, Amine El Azizi, Mohamed Loutou, Mohammed Mansori, Rachid Amrousse, Nadia Faska, Ahmed Bachar

We synthesized Li3xLa2/3− xTiO3 (LLTO, x = 0.125) via solid-state sintering, yielding a structurally stable orthorhombic perovskite with high environmental compatibility. The resulting material was characterized experimentally through X-ray diffraction (XRD), dielectric measurements (permittivity...

Process-Plasma-Material Properties Relationship in the Deposition of Bismuth Sodium Titanate Thin Films by Magnetron Sputtering, Relation procédé–plasma–propriétés des matériaux lors du dépôt de couches minces de titanate de bismuth sodium par pulvérisation cathodique magnétron

Zikriya Khan

This work is dedicated to the synthesis and characterization of ferroelectric piezoelectric Bi0.5Na0.5TiO3 (BNT) thin films. The films were deposited on Si substrates using homemade powder targets by RF magnetron sputtering in an Ar discharge. The target surface analysis, plasma diagnostics, and..., Ce travail est consacré à la synthèse et à la caractérisation de couches minces ferroélectriques et piézoélectriques de Bi₀.₅Na₀.₅TiO₃ (BNT). Les films ont été déposés sur des substrats de silicium (Si) à l’aide de cibles élaborées à partir de poudres synthétisées au laboratoire, par pulvérisation...

Benzo-bis(imidazole) self-assembled monolayers molecular junctions in meta or para conformation: effects of protonation on the electrical and thermal conductances.

Sergio Gonzalez Casal, Simon Pascal, Olivier Siri, Dominique Vuillaume

We report the thermal conductances of molecular junctions made of self-assembled monolayers of benzo-bis(imidazole) molecules, without side groups or functionalized with two phenylamine side groups. In the two cases, when the molecules are connected to the electrodes by thiol anchoring groups in...

Comparison of reverse current mechanisms in GaN Schottky diodes grown on sapphire versus ammonothermal GaN substrates

B Orfao, Mahmoud ABOU DAHER, H Bouillaud, Y Roelens, P Prystawko, R Kucharski, M Bockowski, M Zaknoune

<div><p>In this work, we analyze the reverse current mechanisms in gallium nitride (GaN) Schottky barrier diodes grown on sapphire and native GaN substrates. For the sapphire-substrate sample, two conduction mechanisms are identified: Poole-Frenkel emission (PFE) and trap-assisted...
