Low-Cost CSRR Microwave Sensor for Dielectric Characterization of Liquid Samples

N. Anar, N. Zakaria, M. Hafiz, M. Ali, Z. Ismail Khan, S. Rahim, C. Lenoir, Mohamed Sebbache, Alexandre Barras, Kamel Haddadi

A low-cost complementary split-ring resonator (CSRR) microwave planar sensor is proposed for dielectric characterization of liquid samples. The sensor is realized on a 760μ m-thick polytetrafluoroethylene (PTFE) substrate. Sodium chloride solutions in deionized water with concentrations 0, 1 and 10…

BIN1 gain-of-function in the presynaptic compartment leads to isoform-specific synaptotoxicity

Erwan Lambert, Carla Gelle, Valentin Leclerc, Alejandra Freire-Regatillo, Lucie Liefooghe, Nicolas Barois, Tommy Malfoi, Xavier Hermant, Florie Demiautte, Inès Gallienne, Frank Lafont, Philippe Amouyel, Karine Blary, Sabine Kuenen, Chloé Najdek, Patrik Verstreken, Dolores Siedlecki-Wullich, Pierre Yger, Jean-Charles Lambert, Devrim Kilinc, Pierre Dourlen

Abstract Background Alzheimer’s disease (AD) is associated with strong genetic predisposition and early synaptic loss that correlates with cognitive decline. While genetic determinants are thought to contribute to synaptic vulnerability, their precise role in AD pathogenesis at the synaptic level…

How EAP helps for an experimental validation of the bending moments theory

Thanh-Hang Tran, Mireille Tixier, Simon Skrzypczak, Bacem Zribi, Sofiane Ghenna, Sébastien Grondel, Eric Cattan

The experimental comparison between the quasi-static moment associated with the blocking force and the dynamic moment generated during free deformation remains challenging and can only be achieved under specific experimental conditions. Although bending moment modeling is well established in the…

Enhanced steerable thin-film electrode technology for safer cochlear implantation

Bacem Zribi, Ahmad Itawi, Thanh-Hang Tran, Cédric Plesse, Guillaume Tourrel, Sofiane Ghenna, Sébastien Grondel, Eric Cattan

During cochlear implant surgery, standard electrode arrays are surgically inserted into the scala tympani to stimulate the spiral ganglion cells and rehabilitate hearing in deaf patients. However, due to the stiffness and passive nature of the standard electrode arrays insertion into the tympanic…

Acoustic Impedance of Circular Perforates Subjected to Grazing Flow

Yang Meng, Long Wu, Thomas Humbert, Gwénaël Gabard

This paper develops a semi-empirical acoustic impedance model of circular perforates under a low-Mach-number grazing air flow. The formulation combines a no-flow impedance, appropriate to the high–Strouhal-number regime, and a with-flow impedance given by the low-Strouhal-number asymptotic limit of…

A comprehensive evaluation of an inertial sensor for High-Intensity shocks and vibration analysis in a real tennis context

Lucio Caprioli, Arthur Paté, Elvira Padua, Giuseppe Annino, Vincenzo Bonaiuto, Delphine Chadefaux

The use of inertial sensors (IMUs) in sport performance scenarios has increased in recent years. However, it is necessary to understand the limits of use of these systems and how far they can go in terms of measuring intense shocks and mechanical stimuli, such as impacts in racquet sports. This…

Tailoring oxygen vacancies via Bi substitution in LaFeO3 nanoparticles: efficient, cost-effective, and durable anode electrocatalyst for methanol oxidation reaction

Fawzi Hadji, Ouarda Ben Ali, Mourad Mebarki, Rabah Boukherroub, Kilaparthi Sravan Kumar, Mahmoud Omari, Mohammed Sadok Mahboub

The pursuit of durable and cost-effective non-noble metal-based electrocatalysts for direct methanol fuel cells remains a major challenge. To this end, a series of La1-xBixFeO3 nanoparticles with x = 0, 0.1, 0.2, and 0.3 were synthesized using modified Pechini pathway and assessed as potential…
