Interdigitated-comb piezoelectric phononic crystals for innovative SAW devices

R. Alcorta Galván, C. Croënne, B. Dubus, E. Eustache, A. Ngabonziza, A.-C. Hladky-Hennion

In this paper, piezoelectric phononic crystals made up of interdigitated combs in floating potential condition are studied. Calculation of the dispersion curves shows that, in addition to Bragg bandgaps due to the presence of periodic electrodes, supplementary bandgaps are present corresponding to…

Secure Transmission in NOMA Systems: An Efficient Resource Allocation Strategy Using Deep Learning

Miled Alam, Abdul Karim Gizzini, Laurent Clavier

Deep learning (DL) algorithms have been widely integrated in various aspects of wireless communications research. In this paper, we investigate, in an Internet of Things context, the secrecy energy-efficiency (SEE) of a multi-user downlink non-orthogonal multiple access (NOMA) system in the…

In situ growth of N-doped carbon nanotubes from the products of graphitic carbon nitride etching by nickel nanoparticles

Mariusz Pietrowski, Emilia Alwin, Michał Zieliński, Sabine Szunerits, Agata Suchora, Robert Wojcieszak

The in situ growth of N-doped multi-walled carbon nanotubes (N-MWCNTs) from the products of graphitic carbon nitride (g-C$_3$N$_4$) etching by Ni nanoparticles in a hydrogen atmosphere has been confirmed for the first time. During the etching process of g-C$_3$N$_4$, the building blocks, notably…

Influence of critical micelle concentration of choline-based long chain fatty acid soaps on their antibacterial activity against Methicillin resistant Staphylococcus aureus

Helena Arellano, Tomasz Swebocki, Clémence Le Coeur, Sylvain Prévost, Marwan Abdallah, Véronique Nardello-Rataj, Anne-Laure Fameau

Hypothesis: Antimicrobial resistance (AMR) is a pressing global health concern. ESKAPEE pathogens, such as Methicillin-resistant Staphylococcus aureus (MRSA) are notable of concern in healthcare settings due to their resistance to critical antibiotics. To combat AMR, the development of alternatives…

Investigation of the motif activity of transcription regulators in pancreatic β-like cell subpopulations differentiated from human induced pluripotent stem cells

Eric Leclerc, Mikhail Pachkov, Lisa Morisseau, Fumiya Tokito, Cecile Legallais, Rachid Jellali, Masaki Nishikawa, Amar Abderrahmani, Yasuyuki Sakai

Pancreatic β-cells are composed of different subtypes that play a key role in the control of insulin secretion and thereby control glucose homeostasis. In vitro differentiation of human induced pluripotent stem cells (hiPSCs) into 3D spheroids leads to the generation of β-cell subtypes and thus to…

Retention or repulsion forces induced by bubbles trapped at the base of an immersed microparticle on a substrate

Anna Ipatova, Alexis Duchesne, H N Yoshikawa, Pascal Mariot, Corenthin Leroy, Christine Faille, Ichiro Ueno, Georg F Dietze, Farzam Zoueshtiagh

We explore the potential for air bubble entrapment beneath micrometer-sized particles following immersion. This investigation employs theoretical, numerical, and experimental methodologies, with a focus on the wetting characteristics of both the particle and its substrate. These properties are…

An Incremental Time-Domain Mixed-Signal Matrix-Vector-Multiplication Technique for Low-Power Edge-AI

Kévin Hérissé, Benoit Larras, Bruno Stefanelli, Andreas Kaiser, Antoine Frappé

This paper proposes a time-domain mixed-signal computing architecture for Matrix-Vector Multiplication suited for embedded in-memory computing applications. The system leverages the low data rate of sensors’ data in embedded AI applications to target an energy-efficient implementation of the matrix…

Continuously Beam-Steered Phased Array Antenna Using GaN Varactors for Millimeter-Wave Applications

Abdelaziz Hamdoun, F Medjdoub, Mohamed Himdi, Malek Zegaoui, Olivier Lafond

A continuously steerable beam patch antenna array employing a classical phase shifter based on GaN HEMTs is presented. Here, the GaN HEMTs are used as varactor diodes to achieve the tunability purpose. By controlling the DC bias of these varactors from −2 V to 2 V, the proposed array antenna can…
