A Memristor-Based Bayesian Machine

Artificial intelligence is making major progress today, but it faces a challenge: its considerable energy consumption, which limits its applications and raises environmental issues. It is now well understood that this consumption comes from the separation, in computers, between …

Space-time reveals absolute topological structures (electromagnetic Lorentz invariants)

Since the einsteinian relativistic concepts, it is considered that the idea of lines of force, introduced by Faraday in 1852, should only be considered as an illustration, which does not resist to a change of the reference frame. In …

Toward integrated photonic systems for laser beam control

Free-space laser beams are of core importance in many  fast-growing technologies, including optical communications, 3D imaging and mapping, interconnects, and augmented reality. However, state-of-the-art solutions that allow to generate and control such beams  typically comprise mechanical assemblies, moving parts …

Hydrogen sorption in yttrium-based getter thin films

We investigated the sorption of hydrogen by yttrium-based getters for their application to vacuum wafer-level packaging of microelectromechanical systems. Thin alloy films were co-evaporated under ultra-high vacuum on silicon wafers. Getters were activated by annealing during one hour under …
