Efficiency and Accuracy Evaluation of Multiple Diffusion‐Weighted MRI Techniques Across Different Scanners

Frederik Crop, Clémence Robert, Romain Viard, Julien Dumont, Marine Kawalko, Pauline Makala, Xavier Liem, Imen El Aoud, Aicha Ben Miled, Victor Chaton, Lucas Patin, David Pasquier, Ophélie Guillaud, Benjamin Vandendorpe, Xavier Mirabel, Luc Ceugnart, Camille Decoene, Thomas Lacornerie

Background The choice between different diffusion-weighted imaging (DWI) techniques is difficult as each comes with tradeoffs for efficient clinical routine imaging and apparent diffusion coefficient (ADC) accuracy. Purpose: To quantify signal-to-noise-ratio (SNR) efficiency, ADC accuracy,...

Switchable SAW Resonators and Ladder Filters Composed of Interdigitated Combs

R. Alcorta Galván, Charles Croënne, Bertrand Dubus, B. Loiseaux, E. Eustache, M. Bertrand, A.-C. Hladky-Hennion

This work presents the development of switchable SAW resonators fabricated on a LiNbO3 substrate, which use the Electrical Bragg Bandgap concept to control the resonance frequency. The modification of the electrical condition of electrode arrays shifts their bandgap center frequency which in turn...

Enhanced Fluid Characterization with a Cantilever Microbeaman System Excited by an Embedded Electroactive Source

Victory Elias, Emmanuel Dubois, Nikolay Smagin, Frédéric Rivart, Alex Vercampt, Georges Nassar

When there is a variation in fluid concentration at the free end of a microcantilever, this phenomenon can be utilized in applications such as chemical analysis, biological testing, pharmaceutical screenings, and environmental monitoring. This paper introduces a novel sensor based on a silicon...

Reverse-Bias Current Hysteresis at Low Temperature in GaN Schottky Barrier Diodes

B. Orfao, Mahmoud Abou Daher, R. A. Peña, B. G. Vasallo, S. Pérez, I. Íñiguez-De-La-Torre, G. Paz-Martinez, J. Mateos, Y. Roelens, M. Zaknoune, T. González

In this paper, we report an analysis of reverse current mechanisms observed in GaN Schottky barrier diodes leading to hysteretic behavior of the I\textendashV curves at low temperature. By means of DC measurements from 33 to 475\,K, we demonstrate the presence of two leakage mechanisms when...

Al‐Rich AlGaN Channel High Electron Mobility Transistors on Silicon: A Relevant Approach for High Temperature Stability of Electron Mobility

Julien Bassaler, Jash Mehta, Idriss Abid, Leszek Konczewicz, Sandrine Juillaguet, Sylvie Contreras, Stéphanie Rennesson, Sebastian Tamariz, Maud Nemoz, Fabrice Semond, Julien Pernot, Farid Medjdoub, Yvon Cordier, Philippe Ferrandis

Ultrawide bandgap (UWBG) semiconductors offer new possibilities to develop power electronics. High voltage operation for the off‐state as well as high temperature stability of the devices in on‐state are required. More than AlGaN/GaN heterostructures, AlGaN/AlGaN heterostructures are promising...

Neuromorphic Coincidence Detector for Interaural Time Difference Encoding and Sound DOA Estimation

Eugénie Dalmas, François Danneville, Michael Bocquet, Christophe Loyez

Eight decades ago, the medial superior olive (MSO) responsible for the extraction of the interaural time difference (ITD) was described as a combination of coincidence detection neurons and delay lines by Jeffress, a model largely used in spiking sound source localization systems. Coincidence...
