Theoretical Investigation of the Influence of Temperature and Indium Composition on Intersubband Absorption in InGaN/GaN QW

Lynda Chenini, Abdelkader Aissat, Said Nacer, Samuel Dupont, Jean-Pierre Vilcot

The optical and structural properties of a Zinc Blende (ZB) InGaN single quantum well (QWs) grown on a GaN barriers have been analyzed theoretically, considering different indium (In) amounts and temperature (T) levels. To achieve this, the concentration of indium was varied from 0% to 40%. The…

A Compact Conformal Printed Dipole Antenna for UAV Telemetry Applications

Zeyneb Mordi, Zahir Hamouda, Mohand Lagha, Tuami Lasri

This paper presents a compact conformal dipole antenna operating at 433 MHz, designed to replace the conventional dipole antenna of an unmanned aerial vehicle (UAV). The key innovation lies in directly printing the proposed antenna onto the UAV's tail boom, integrating the antenna seamlessly…

Early Measurements of Silicon Axisymmetric MEMS Gyro

Lucas Hudeley, Raphaël Levy, Maxime Duquesnoy, Jérémy Bonhomme, Olivier Le Traon, Alain Bosseboeuf, Marc Faucher, Jérôme Juillard, Benjamin Walter

This paper presents preliminary results of a new silicon MEMS gyro. This MEMS Coriolis Vibratory Gyroscope (CVG) is based on link elements with counterweight that balance the proof mass momentum assuring its insulation from the environment. We demonstrated high quality factor up to 100 000 for a…

Hybridising photovoltaics and thermoelectrics: A detailed-balance analysis

Alexis Vossier, Etienne Blandre, Rodolphe Vaillon

The combination of photovoltaic and thermoelectric converters could potentially lead to an improvement in the efficiency with which solar energy is converted into electricity, thanks to the improved exploitation of the residual heat generated in the PV cells. Using the detailed balance formalism,…

Demonstration of reservoir computing in a double-drum resonator through sideband pumping approach

T Farah, P Laly, B Djafari-Rouhani, Yan Pennec, X Zhou

Reservoir computing (RC) is a computational paradigm inspired by the process of information transfer between neurons in the brain. Recently, physical reservoir computing based on the nonlinear dynamics of a system has been studied in many areas of physics. Within these systems,…

Sparse guided wave imaging in highly anisotropic plates with phase skewing and amplitude focusing compensation

Pierre Goislot, Guillemette Ribay, Emmanuel Moulin, Lynda Chehami

This paper introduces a sparse beamforming algorithm designed to compensate for guided wave dispersion while addressing phase skewing and energy focusing in highly anisotropic composite plates. Developed for structural health monitoring, this algorithm targets impact-induced defects, such as barely…

Topological phase transitions of non-Hermitian periodic and disordered elastic systems

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

Topological states have been extensively explored across diverse wave systems in recent decades. However, most research has focused on the periodic and Hermitian systems, while the roles of non-Hermiticity and disorder in topological properties need to be further explored, especially for two-…

Effects of La2O3 on structure and mechanical properties of sodium borosilicate glass

Meriem Ben Zennou, Ahmed Bachar, Meriem Chrifi Alaoui, Frédéric Jenot, Rachid Amrousse, Aurélien Canizares, Yann Vaills, Stuart Hampshire, Mohamed Rguiti, Assia Mabrouk

To develop rare-earth-doped borosilicate glasses with enhanced mechanical properties, lanthanum sodium borosilicate glasses were successfully synthesized using a fusion method. The glass composition was (mol.%): 55SiO2 - 25B2O3 – (20-x)Na2O - xLa2O3 (x = 1, 2, 3, 4, and 5). The primary aim was to…

Mechanisms of DNA Damage Recognition by UDG and PARP1 in the Nucleosome

Safwen Ghediri, Parvathy A Sarma, Vinnarasi Saravanan, Corinne Abbadie, Ralf Blossey, Fabrizio Cleri

<div><p>The DNA base-excision repair (BER) pathway shares the second part of its enzymatic chain with the single-strand break (SSB) repair pathway. BER is initiated by a glycosylase, such as UDG, while SSBR is initiated by the multifunctional enzyme PARP1. The very early steps in the…
