Sparse Coding-based Multichannel Spike Sorting with the Locally Competitive Algorithm

Alexis Melot, Fabien Alibart, Pierre Yger, Sean Wood

Spike sorting is a crucial step in the analysis of multichannel neural signals that enables the identification of individual neurons’ activity. However, the limited availability of low-power neuromorphic spike sorting methods is due to the difficulty of processing high-density multichannel...

impact of resynchronization errors on the quality localization of defects in reverberant plates

Omar Bouchakour, Lynda Chehami, Emmanuel Moulin

In the context of structural health monitoring (SHM), recent research has been carried out to take advantage of the correlation of ambient noise to locate and characterize defects in reverberant plates. The back-propagation-based imaging algorithms developed in this way require that the signals...

Analysis of Trapping Effects on AlInN/GaN High Electron Mobility Transistors with Pulsed Electrical Measurements Under Visible and Infrared Illumination

Raphaël Strenaer, Yannick Guhel, Christophe Gaquière, Bertrand Boudart

The aim of this article is to show that it is possible to rapidly estimate the activation energies of electron traps in AlInN/GaN transistors operating at room temperature by combining pulsed electrical measurements with photoionization techniques using infrared illumination. This technique avoids...

Atmospheric-Pressure Operation of All-Solid-State Batteries Enabled by Halide Solid Electrolyte

Benjamin Hennequart, Maria Platonova, Ronan Chometon, Thomas Marchandier, Alessandro Benedetto, Elisa Quemin, Romain Dugas, Christophe Lethien, Jean-Marie Tarascon

All-solid-state batteries aim to provide increased safety and higher energy density for next-generation energy storage. However, challenges remain due to volume changes and inadequate contact between the cathode active material and solid electrolyte particles, leading to poor cyclability. This...

NOMA-MCM strategies in transmission and reception for advanced vehicular communications in 5G and beyond, Stratégies NOMA-MCM en transmission et réception pour les communications véhiculaires avancées de la 5G et au-delà

Alain Allouis

The realm of intelligent transportation hinges upon robust vehicular communication infrastructure, vital for traffic management, road monitoring, Internet of Things (IoT) accessibility, and driver/passenger information. While the conventional IEEE802.11p standard has long dominated this domain, the..., Le domaine des transports intelligents repose sur une infrastructure robuste de communication véhiculaire, essentielle à la gestion du trafic, à la surveillance des routes, à l'accessibilité à l'Internet des objets (IoT) et aux informations des conducteurs/passagers. Alors que la norme...

Improvement of linearity in trap-rich substrates for radio frequency applications: Which of donor and acceptor trap is the best?

Justine Philippe, Jean-François Robillard, Daniel Gloria, Emmanuel Dubois

This paper investigates the effect of volume traps intentionally introduced into a silicon-on-insulator (SOI) substrate by inserting a layer of polysilicon beneath buried oxide. In radio frequency applications, this type of substrate, referred to as trap-rich, is known to considerably reduce the...

Short-time expansion of one-dimensional Fokker-Planck equations with heterogeneous diffusion

Tom Dupont, Stefano Giordano, Fabrizio Cleri, Ralf Blossey

We formulate a short-time expansion for one-dimensional Fokker-Planck equations with spatially dependent diffusion coefficients, derived from stochastic processes with Gaussian white noise, for general values of the discretization parameter 0 ⩽ α ⩽ 1 of the stochastic integral. The kernel of the...
