When Side-Channel Attacks Break the Black-Box Property of Embedded Artificial Intelligence
Benoit Coqueret, Mathieu Carbone, Olivier Sentieys +1
Artificial intelligence, and specifically deep neural networks (DNNs), has rapidly emerged in the past decade as the standard for several tasks from specific advertising to object…
Observation by SANS and PNR of pure Néel-type domain wall profiles and skyrmion suppression below room temperature in magnetic [Pt/CoFeB/Ru] multilayers
Victor Ukleev, Fernando Ajejas, Anton Devishvili +9
We report investigations of the magnetic textures in periodic [Pt(1 nm)/(CoFeB(0.8 nm)/Ru(1.4 nm)] multilayers using polarised neutron reflectometry (PNR) and small-angle ne…
The optical absorption in indirect semiconductor to semimetal PtSe2 arises from direct transitions
Marin Tharrault, Sabrine Ayari, Mehdi Arfaoui +12
is a van der Waals material transitioning from an indirect bandgap semiconductor to a semimetal with increasing thickness. Its absorption threshold has been conjectur…
Helical coil design with controlled dispersion for bunching enhancement of the TNSA protons
A Hirsch-Passicos, C L C Lacoste, F André +4
The quality of the proton beam produced by Target Normal Sheath Acceleration (TNSA) with high power lasers can be significantly improved with the use of helical coils. While they s…
Module-wise Training of Neural Networks via the Minimizing Movement Scheme
Skander Karkar, Ibrahim Ayed, Emmanuel de Bézenac +1
Greedy layer-wise or module-wise training of neural networks is compelling in constrained and on-device settings where memory is limited, as it circumvents a number of problems of…
Neuromorphic weighted sums with magnetic skyrmions
Tristan da Câmara Santa Clara Gomes, Yanis Sassi, Dédalo Sanz-Hernández +7
Integrating magnetic skyrmions into neuromorphic computing could help improve hardware efficiency and computational power. However, developing a scalable implementation of the weig…
