Characterization of a Frequency Dependent Reflective Surface at 300 GHz: Absorption, Bandwidth and Losses

Frédéric Dutin, Victor Torres, Jorge Teniente, Abdu Subahan Mohammed, Rita Younes, Pascal Szriftgiser, Guillaume Ducournau

This paper presents experimental assessment of the performance of a passive Reconfigurable Intelligent Surface (RIS) in the 300 GHz band. Characterization steps make use of a free space testbed based on a 220–325 GHz Vector Network Analyzer. The reflective surface is characterized by referencing...

Stochastic thermodynamics of holonomic systems

Stefano Giordano, Giuseppe Florio, Giuseppe Puglisi, Fabrizio Cleri, Ralf Blossey

<div><p>Stochastic thermodynamics is a recently developed framework designed to describe the behavior of small systems in contact with one or more thermal reservoirs. Originally applied to systems of unconstrained particles, it has provided deep insights into the thermodynamic behavior...

Effects of temperature, humidity and disorder in phase transformation phenomena of multi-stable systems

Vincenzo Fazio, Giuseppe Florio, Stefano Giordano, Giuseppe Puglisi, Nicola M Pugno

Multi-stable behavior at the microscopic length-scale is fundamental for phase trans- formation phenomena observed in many materials. These phenomena can be driven not only by external mechanical forces but are also crucially influenced by disorder and thermal fluctuations. Disorder, arising from...

First demonstration of vertical AlGaN P-i-N diodes grown on silicon substrate for Next-Generation power electronics

Jash Mehta, Abdelkhalek Sefssafi, Antoine Barbier, Stephanie Rennesson, Fabrice Semond, Julien Brault, F Medjdoub

In this work, we report the first demonstration of quasi-vertical AlGaN PiN diodes grown directly on silicon substrates, paving the way toward high-performance, low-cost power electronics. GaN and AlGaN heterostructures were grown on 2-inch silicon wafers via molecular beam epitaxy. The AlGaN diode...

Proposed Experiments for Detecting Contextual Hidden Variables

Konstantinos Papatryfonos, Louis Vervoort

We propose two quantum experiments – modified Bell tests – that could detect contextual hidden variables underlying quantum mechanics. The experiments are inspired by hydrodynamic pilot-wave systems that mimic a wide range of quantum effects and exhibit a classical analog of contextuality. To...

Traitement de signaux neuronaux à base de réseaux de neurones à décharges optimisés pour accélérateurs neuromorphiques, Processing neural signal with spiking neural networks optimized for neuromorphic hardware

Alexis Melot

Les Interfaces Cerveau-Machine (ICM) reposent sur le tri de potentiels d'action pour décoder l'activité des neurones individuels, une méthode centrale pour des neuroprothèses et l'étude des circuits cérébraux. Avec l'amélioration des sondes neuronales incluant une densité..., Brain-Machine Interfaces (BMIs) depend on sorting action potentials (spike sorting) to decode individual neuron activity, an essential process in both neuroprosthetics and the study of neural circuits. Advances in neural probes, particularly the increased electrode density, have dramatically...

Exploring ultrasound for monitoring phospholipid content in edible oils

Safia Lemlikchi, Johan Carlson, Samir Hadjal, Mohammed Asmani, Hakim Djelouah

This study investigates the feasibility of using ultrasound to monitor phospholipid (PL) content in edible oils during refining, aiming to establish a reliable alternative or complementary method to conventional physico-chemical analyses. Ultrasonic measurements were performed on soybean oil...
