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…

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,…

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,…

Electrocatalytic upcycling of polyethylene terephthalate to formic acid and hydrogen fuels using CoCuO /MXene catalyst

Zhi-Ran Yu, Meng-Xin Ji, Zhao-Hui Zhang, Yi Zhang, Alexandre Barras, Ahmed Addad, Long-Cheng Tang, Yu-Hua Chi, Pascal Roussel, Sabine Szunerits, Rabah Boukherroub

A promising way to address environmental problems caused by plastic waste is through its upcycling into renewable energy and resources. With annual production reaching millions of tons, one of the most widely single-use daily plastics, polyethylene terephthalate (PET), has recently been…

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…

Cancer classification through the selection of genes extracted from microarray data

Mohammed Maiza, Samira Chouraqui, Chahira Cherif, Abdelmalik Taleb-Ahmed

In this work we propose to compare tree methods for feature selection in the binary classification context. We focus on the case where the number of variables is very large and much more important than the sample size, as is the case in most microarray data. Four classification algorithms were…

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…
