Electrical and ion beam analyses of yttrium and yttrium-titanium getter thin films oxidation
Yttrium, titanium, and yttrium-titanium getter thin films were elaborated on silicon by coevaporation in ultrahigh vacuum. Y-Ti films exhibit nanometric crystallites size (18–35 nm) leading to a very high grain boundary density, which is a favorable microstructure for activation …

Discovering the origins of the universe with the QUBIC telescope
QUBIC (QU Bolometric Interferometer for Cosmology) is a cosmology experiment designed to study the so-called inflation period, a period during which the Universe expanded extremely rapidly immediately after the Big-Bang. The characterization of the inflation will be done …

Topological opto-mechanical resonator for robust colocalization of light and sound
Researchers have proposed a way to robustly co-localize light and sound at the nanoscale with enhanced optomechanical interactions. It is phenomenal to observe the identical twin behavior of light and sound in the GaAs/AlAs heterostructures. This inherent property …

Taking inspiration from the brain to alleviate catastrophic forgetting in artificial intelligence
For several years now, artificial intelligence has made considerable progress thanks to the implementation of deep learning: computer programs called deep artificial neural networks are now capable of learning very complex tasks. However, these programs suffer from a considerable …
