Optimisation of a non contact coil / magnet actuator: geometry, nonlinearities and thermal heating

Marguerite de La Bigne, Eric Cattan, Sofiane Ghenna, Sébastien Grondel, Olivier Thomas

This article presents the optimisation of an electromagnetic actuator composed of a toroidal coil and a cylindrical magnet positioned along the coil’s axis that may be used for non-contact measurement of excitation of structures, for vibration testing, electromagnetic shunts or energy harvesting.…

Dynamics of the harmonic acoustic pneumatic source for active control of time-varying tonal noise

Alexandre Schiavini, Philippe Micheau, Pierre Grandjean, Gwénaël Gabard, Thomas Humbert

The Harmonic Acoustic Pneumatic Source (HAPS), a mechanical airflow modulator, is a promising alternative to loudspeakers as secondary sources for the active control of harmonic noise, thanks to its ability to generate high sound pressure levels and to precisely control signal frequency, phase, and…

Microcavités pour composants RF-SOI-CMOS ultra-rapides pour application 5G et delà, Microcavities for ultra-fast RF-SOI-CMOS components for 5G applications and beyond

Daniel Gheysens

Le développement des standards de communication mobile impose des exigences toujours plus strictes aux commutateurs radiofréquence (RF), notamment en termes de bande passante, pertes, linéarité et bruit. La technologie RF SOI-CMOS partiellement déplétée s’est imposée comme la solution dominante…, The development of mobile communication standards imposes increasingly stringent requirements on radio frequency (RF) switches, particularly in terms of bandwidth, losses, linearity, and noise. Partially depleted SOI-CMOS RF technology has emerged as the dominant solution thanks to an optimal…

Quantum Coherent Transport of 1D Ballistic States in Second-Order Topological Insulator Bi4⁢Br4

Jules Lefeuvre, Masaru Kobayashi, Gilles Patriarche, Nathaniel Findling, David Troadec, Meydi Ferrier, Sophie Guéron, Hélène Bouchiat, Takao Sasagawa, Richard Deblock

We investigate quantum transport in micrometer-sized single crystals of Bi$_4$Br$_4$, a material predicted to be a second-order topological insulator. 1D topological states with long phase coherence times are revealed via the modulation of quantum interferences with magnetic field and gate voltage…

Inflammatory stimulus enhances synaptic material uptake by adult APP microglia in a microfluidic neuron–microglia co-culture model

Dolores Siedlecki-Wullich, Anne-Marie Ayral, Lukas Iohan, Célia Lemeu, Valérie Buiche, Karine Blary, Julien Chapuis, Fanny Eysert, Delphine Beury, Myriam Delacre, David Hot, Takahiro Masuda, Klaus-Peter Knobeloch, Marco Prinz, Jean-Charles Lambert, Devrim Kilinc

Microglia play a critical role in synapse remodeling and neuroinflammation, both of which are dysregulated in Alzheimer’s disease (AD). However, most in vitro models rely on neonatal or immortalized microglia, limiting their relevance to adult pathophysiological context. Here, we present a…
