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...

Colloidal Quantum Dots Thin Films: A Theoretical Insight Into Optical Efficiency for Optoelectronic Applications

Bilal Chehaibou, Peter Reiss, Emmanuel Lhuillier, Gabriel Mugny, Christophe Delerue, Arthur Arnaud

A growing number of scientific publications have shown during this last decade the potential of colloidal quantum dots (QDs) thin films for optical sensing, such as photonic applications, multispectral imaging, or infrared (IR) depth imaging. In this context, it appears interesting to consolidate...

A Temporal Filter to Extract Doped Conducting Polymer Information Features from an Electronic Nose

Wiem Haj Ammar, Aicha Boujnah, Antoine Baron, Aimen Boubaker, Adel Kalboussi, Kamal Lmimouni, Sébastien Pecqueur

Identifying relevant machine learning features for multi-sensing platforms is both an applicative limitation to recognize environments and a necessity to interpret the physical relevance of transducers’ complementarity in their information processing. Particularly for long acquisitions, feature...

Surface acoustic wave confinement inside uncorrelated distributions of subwavelength scatterers

Thibault Deletang, Adnane Noual, Bernard Bonello, Roman Buisine, Yan Pennec, Bahram Djafari-Rouhani

We report an experimental study of surface acoustic wave (SAW) localization and propagation in random metasurfaces composed of Al scatters using pump–probe spectroscopy. Thanks to this technique, wideband high frequency acoustic modes are generated, and their dynamical propagation directly from...

Terahertz molecular water laser using quantum cascade laser pumping

L. Juppet, Alexandra Khabbaz, J. Lampin, O. Pirali

Molecular lasers pumped by quantum cascade laser (QCL) open new possibilities for THz generation and its numerous applications, in particular, for high resolution molecular spectroscopy. In this article, a THz water laser pumped by a mid-infrared QCL was demonstrated using the broad tunability of...

Demonstration of avalanche capability in 800 V vertical GaN-on-Silicon diodes

Youssef Hamdaoui, Idriss Abid, Sondre Michler, Katir Ziouche, F Medjdoub

High-quality pseudo-vertical p-n diodes using a GaN-on-silicon heterostructure are reported. An optimized fabrication process including a beveled deep mesa as edge termination and reduced ohmic contact resistances enabled high on-state current density and low onresistance. A uniform breakdown...
