Tilted columnar metal film as transducer of transverse coherent acoustic phonons in picosecond acoustics

A. Chargui, N. Martin, G. Ferro, Arnaud Devos

Picosecond acoustics has been widely used to study thin film elasticity, hypersound attenuation, and adhesion of thin films to substrates. A major limitation of the technique is its restriction to only longitudinal waves. Although work has been reported on the ultrafast generation and detection of…

Quantification and mitigation of the effect of resynchronization errors in ultrasound sensor network for passive imaging in elastic plates

Omar Bouchakour, Emmanuel Moulin, Lynda Chehami, Nikolay Smagin

The problem of signal desynchronization in passive imaging based on noise correlation for defect detection in elastic plates is investigated. Although a post-processing resynchronization process relying on the symmetry of noise correlation functions can be applied prior to the imaging algorithm,…

TileChain: A Blockchain-Based Framework for Security Service Management For Vehicular Communications

Ahmed Didouh, Anthony Bahadir Lopez, Houda Labiod, Yassin El Hillali, Atika Rivenq, Mohammad Abdullah Al Faruque

Vehicular communications have become essential for functional and road safety purposes due to the development of vehicle fleets. However, these communications have made vehicles more vulnerable to cyber-attacks. The security of data exchanges in vehicular networks currently relies on a centralized…

Boosting the performances of semitransparent organic photovoltaics via synergetic near-infrared light management

Tao Xu, Baozhong Deng, Kaiwen Zheng, Hongyu Li, Zihan Wang, Yunbo Zhong, Chengxi Zhang, Gaëtan Lévêque, Bruno Grandidier, Renaud Bachelot, Mona Tréguer-Delapierre, Yabing Qi, Shenghao Wang

Semitransparent organic photovoltaics (ST‐OPVs) offer promising prospects for application in building‐integrated photovoltaic systems and greenhouses, but further improvement of their performance faces a delicate trade‐off between the two competing indexes of power conversion efficiency (PCE) and…

Ab Initio Study of the Crystalline Structure of HgS under Low and High Pressure

Ahmed Amine Aidouni, Abdelkader Aissat, Mounir Ould-Mohamed, Mohamed El Amine Benamar, Samuel Dupont, Jean Pierre Vilcot

This study analyzes the lattice dynamics of HgS under various pressures using ab initio self-consistent calculations based on the plane-wave method (PW) and generalized gradient approximation (GGA). The static study, performed by enthalpy calculations, predicts that the transition from the cinnabar…

Photonics-enabled 1.04-Tbit/s Aggregated Data-rate in the 600-GHz-band

Guillaume Ducournau, Pascal Szriftgiser, Yuma Kawamoto, Weijie Gao, Abdu Subahan Mohammed, Malek Zegaoui, Mohammed Zaknoune, Tadao Nagatsuma

We demonstrate in this work the use of a waveguide-integrated THz photodiode in the 600 GHz band, combined with a waveguide-based receiver. Leveraging on the wide available bandwidth of this association, beyond 1 terabit per second aggregated data-rate is reached with a bit-error-rate performance…

Emb-trattunet: a novel edge loss function and transformer-CNN architecture for multi-classes pneumonia infection segmentation in low annotation regimes

Fares Bougourzi, Fadi Dornaika, Amir Nakib, Abdelmalik Taleb-Ahmed

One of the primary challenges in applying deep learning approaches to medical imaging is the limited availability of data due to various factors. These factors include concerns about data privacy and the requirement for expert radiologists to perform the time-consuming and labor-intensive task of…

Atomistic insights into the nucleation and growth of hexagonal boron nitride and graphene heterostructures

Mohamed Achehboune, Kazem Zhour, Jaroslaw Dabrowski, Dominique Vignaud, Max Franck, Mindaugas Lukosius, Jean-François Colomer, Luc Henrard

Graphene and hexagonal boron nitride (hBN) are two-dimensional (2D) materials with a similar atomic structure but drastically different although complementary electronic properties. The large-scale synthesis of h-BN/graphene heterostructures with high crystallographic quality is required to fully…

On the reduction of gas permeation through the glass windows of micromachined vapor cells using Al₂O₃ coatings

C. Carlé, A. Mursa, P. Karvinen, S. Keshavarzi, M. Abdel Hafiz, V. Maurice, R. Boudot, N. Passilly

Stability and precision of atomic devices are closely tied to the quality and stability of the internal atmosphere of the atomic vapor cells on which they rely. Such an atmosphere can be stabilized by building the cell with low permeation materials such as sapphire or aluminosilicate glass in…
