Structural basis for UDG identifying DNA damage in the nucleosome

Safwen Ghediri, Ralf Blossey, Fabrizio Cleri

The DNA base-excision repair (BER) pathway is initiated by a glycosylase, such as UDG, which identifies and removes a wrong base incorporated in the DNA sequence. The very early steps in the identification of the DNA damage are crucial to the correct initiation of the repair chain, and become even...

Droplet velocity in both limits of low and high soluble surfactants in a Hele-Shaw cell: experimental and analytical results

Jacques-Teïva Baué, Adrien Gans, Lucas Jannin, Benjamin Reichert, Isabelle Cantat, Marie-Caroline Jullien

The transport of droplets in microfluidic channels is strongly dominated by interfacial properties, which makes it a relevant tool for understanding the mechanisms associated with the presence of more or less soluble surfactants. In this paper, we show that the mobility of an oil droplet pushed by...

Object detection based on Logistic Objects in Context (LOCO) dataset: an improved dataset split and performance on NVIDIA Jetson Nano

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

The Logistics Objects in Context (LOCO) dataset is the first and only public dataset that integrates multiple logistic objects in a real logistics context. It is dedicated to object detection applications. However, the dataset is small and has unbalanced classes annotations problem. In this study,...

XAI for wireless communications

Abdul-Karim Gizzini, Yahia Medjahdi, Ali Ghandour, Laurent Clavier, Mouna Ben Mabrouk

The native artificial intelligence (AI) concept is envisioned to be integrated into 6G future communications. Due to the black box nature of the majority of AI models, the decision-making strategy used by these models is critical, risky, and challenging. This issue can be tackled by developing...

Locally sealed microfabricated vapor cells filled from an ex situ Cs source

Linda Peroux, Arthur Dewilde, Ravinder Kumar Chutani, Aurelien Mazzamurro, Jérémy Bonhomme, Andrei Mursa, Jean-François Clément, Abdelkrim Talbi, Philippe Pernod, Nicolas Passilly, Vincent Maurice

Microfabricated alkali vapor cells are key to enable miniature devices such as atomic clocks and optically pumped magnetometers with reduced size, weight and power. Yet, more versatile fabrication methods are still needed to further expand their use cases. Here, we demonstrate a novel approach to...

Crystallinity in niobium oxides: A pathway to mitigate two-level-system defects in niobium three-dimensional resonators for quantum applications

Y. Kalboussi, I. Curci, F. Miserque, David Troadec, N. Brun, M. Walls, G. Jullien, F. Eozenou, M. Baudrier, L. Maurice, Q. Bertrand, P. Sahuquet, T. Proslier

Materials imperfections in Nb-based superconducting quantum circuits-in particular, two-levelsystem (TLS) defects-are a major source of decoherence, ultimately limiting the performance of quantum computation and sensing. Thus, identifying and understanding the microscopic origin of possible TLS...

SnatchML: Hijacking ML Models Without Training Access

Mahmoud Ghorbel, Halima Bouzidi, Ioan Marius Bilasco, Ihsen Alouani

The widespread deployment of Machine Learning (ML) models has been accompanied by the emergence of various attacks that threaten their trustworthiness and raise ethical and societal concerns. One such attack is model hijacking, where an adversary seeks to repurpose a victim model to perform a...
