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…

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…

Bottom gated in-plane InSb nanostructures on GaAs(111)B grown by selective area epitaxy

Clément Barbot, Christophe Coinon, Maxime Berthe, Yves Deblock, Qianqian Lan, Etienne Okada, L. Thomas, Pierre Capiod, Coline Demoncheaux, Rafal E Dunin-Borkowski, Philipp Ebert, Bruno Grandidier, Ludovic Desplanque

This work presents a method of achieving high-quality in-plane InSb nanowires on a highly mismatched GaAs (111)B substrate through the combination of atomic hydrogen-assisted selective area molecular beam epitaxy and extreme Sb-rich conditions. By inserting an InGaP barrier layer on top of the…

Coherent electronic transport in HgTe nanostructures grown by selective area epitaxy

Nicolas Chaize, Xavier Baudry, Yves Deblock, Maxime Berthe, Bruno Grandidier, Ludovic Desplanque, Philippe Ballet, Hermann Sellier

This paper reports on the quantum coherent properties of in-plane HgTe nanodevices obtained by selective area growth (SAG) on CdTe substrates using a silicon dioxide mask. Low-temperature magneto-transport measurements were performed on devices with a ring geometry to extract the phase coherence…

Rapid characterisation of millimetre-tall vertically aligned carbon nanotube arrays: growth optimisation by tuning the catalyst film thickness

Xinghai Zhao, Johannes Eduard Stubbe, Jin Chuen Kenneth Ho, Putu Andhita Dananjaya, Wen Siang Lew, Philippe Coquet, Beng Kang Tay

This study aims to establish a quick and sustainable approach for optimising the growth of millimetre-tall vertically aligned carbon nanotube (VACNT) arrays through simple catalyst tuning. To achieve this swiftly, a rapid and handy characterisation protocol is essential. Herein, we propose and…

Direct impedance eduction of acoustic liners in multimodal ducts with shear flows

Jinyue Yang, Thomas Humbert, Joachim Golliard, Gwénaël Gabard

Impedance eduction of acoustic liners with flow is usually performed under the assumption of a uniform mean flow and in the presence of an incident plane wave. However, recent studies have demonstrated that shear flow significantly influences the propagation of sound waves and their interaction…

Dynamics of the harmonic acoustic pneumatic source for active control of time-varying tonal noise

Alexandre Schiavini, Philippe Micheau, Pierre Grandjean, Gwénaël Gabard, Thomas Humbert

The Harmonic Acoustic Pneumatic Source (HAPS), a mechanical airflow modulator, is a promising alternative to loudspeakers as secondary sources for the active control of harmonic noise, thanks to its ability to generate high sound pressure levels and to precisely control signal frequency, phase, and…
