Hydrodynamic performance analysis and optimization of a concave-bladed Archimedes screw turbine using coupled analytical modeling and CFD simulation

Chouaib Sayaghi, Mohammed Remaidi, Hicham Mastouri, Amine Ennawaoui, Othmane Marbouh, Mohamed El Jouad, Chouaib Ennawaoui

This study presents an innovative analytical-numerical model for the optimization of low-head Archimedes screw turbines, based on the synergistic coupling between blade concavity and screw pitch. Unlike conventional approaches that treat these parameters in isolation, existing models fail to…

Interface-driven giant piezoelectric enhancement in ScN/AlN bilayers and its comparison with Sc0.5Al0.5N alloys under epitaxial strain: A first-principles study

Imene Cherair, Abdelkrim El Hadi Khediri, Ali Soltani

We present a comparative first-principles study of and alloys, as well as wurtzite ScN/AlN and GaN/AlN bilayers, focusing on their piezoelectric and elastic properties under epitaxial strain. Our results reveal a dramatic enhancement of the out-of-plane piezoelectric response in ScN/AlN bilayers…

Experimental and mathematical models reveal that AMPK modulates circadian clock gene expression and period through NAD+-dependent regulation of Bmal1

Alan Vandenberghe, Pauline Delpierre, Raoul Torero-Ibad, Pierre Leclerc, Anthony Treizebre, Alexandre Berthier, Laurent Heliot, Helene Duez, Bart Staels, Philippe Lefebvre, Alessandro Furlan, Marc Lefranc

The circadian clock allows living systems to anticipate environmental daily variations by scheduling cellular mechanisms according to the time of the day. The reciprocal interplay between metabolism and circadian clock is essential for energy homeostasis, and the disruption of metabolic clock…

Les isolants topologiques constituent une classe de matériaux périodiques caractérisés par des propriétés topologiques intrinsèques permettant un contrôle particulier de la propagation des ondes. Initialement développés dans le contexte des systèmes quantiques électroniques, ces concepts ont…, Topological insulators constitute a class of periodic materials characterized by intrinsic topological properties that enable enhanced control over wave propagation. Initially developed in the context of quantum electronic systems, these concepts have subsequently been extended to artificial…

Bragg resonator cavity for time-resolved microwave conductivity measurement

Ali Ghaddar, M. Boutghatin, Patrick Ropa, M. Toufaily, Bator Khol, Sebastien Saitzek, Jean-François Blach, N. Tentillier, Redouane Douali

Time-resolved microwave conductivity (TRMC) is a well-established technique for characterizing charge carriers in materials. This technique relies on a sensitive resonant microwave cavity to detect small changes in the material’s conductivity induced by a laser pulse. Conventional TRMC systems…

Disorder‐Assisted Topological States and Critical Couplings in Continuous Elastic Metaplates

Runcheng Cai, Minle Yu, Yabin Jin, Bahram Djafari-Rouhani, Yanxun Xiang, Xiaoying Zhuang, Timon Rabczuk

ABSTRACT Precise manipulation of elastic waves in continuous solid‐state media is important for enhancing wave‐matter interactions and enabling applications such as energy harvesting, nondestructive testing, sensing, and on‐chip signal processing. Disorder is typically regarded as detrimental to…
