Production of mm-Wave epiwafers of GaN on Si grown by NH3-MBE

Abdennacer Benali, Elodie Carneiro, Lyes Ben Hammou, Kathia Harrouche, Etienne Okada, Sebastian Tamariz, Stéphanie Rennesson, Farid Medjdoub, Fabrice Semond

With 5G-advanced, the data consumption between wireless equipment is predicted to follow exponential growth. To allow that, there is a need to increase the bandwidth with RF chips that fulfill 2 criteria: performance in the range of 24-100 GHz and affordability, for large scale deployment. Thanks...

The ‘very moment’ when UDG recognizes a flipped-out uracil base in dsDNA

Vinnarasi Saravanan, Nessim Raouraoua, Guillaume Brysbaert, Stefano Giordano, Marc F. Lensink, Fabrizio Cleri, Ralf Blossey

Abstract Uracil-DNA glycosylase (UDG) is the first enzyme in the base-excision repair (BER) pathway, acting on uracil bases in DNA. How UDG finds its targets has not been conclusively resolved yet. Based on available structural and other experimental evidence, two possible pathways are under...

Topological Interface States in a One-Dimensional Mesoscopic Crystal Using Su-Schrieffer-Heeger Model

Noura Ezzahni, Mohammed Elaouni, Soufyane Khattou, Madiha Amrani, Mohamed El Ghafiani, Yamina Rezzouk, El Houssaine El Boudouti, Bahram Djafari-Rouhani

We investigate the existence of topological interface states between two periodic comb-like mesoscopic crystals with different topological properties based on the Su-Schrieffer-Heeger (SSH) model. This model enables us to predict the existence of topological interface states between two connected...

Two Types of Bound States in the Continuum in Photonic Comb Structure

Yamina Rezzouk, Soufyane Khattou, Mohamed El Ghafiani, Madiha Amrani, El Houssaine El Boudouti, Abdelkrim Talbi, Bahram Djafari-Rouhani

We propose the design of a comb-shaped cavity that can support several BICs when attached to a waveguide. The cavity consists of a finite comb made of one stub of length placed between two stubs of length via two guides of length and the whole comb is attached vertically along a waveguide. In order...

Class-Specific Dataset Splitting for YOLOv8: Improving Real-Time Performance in NVIDIA Jetson Nano for Faster Autonomous Forklifts

Chaouki Tadjine, Abdelkrim Ouafi, Abdelmalik Taleb-Ahmed, Yassin El Hillali

This research examines a class-specific YOLOv8 model setup for real-time object detection using the Logistics Objects in Context dataset, specifically looking at how it can be used in high-speed autonomous forklifts to enhance obstacle detection. The dataset contains five common object classes in...

Modeling of Surface-Emitting Terahertz Quantum Cascade Laser Based on Difference Frequency Generation

A Hamadou, Jean-Luc Thobel

In this paper, we propose a simple method to calculate the THz field and THz power generated via intracavity difference frequency generation in a dual-wavelength mid-infrared quantum cascade laser. The approach is based on using a surface emission scheme in the nonlinear waveguide. The results show...
