Contact forces move a particle along an acoustically excited surface: Case of permanent contact

Vladislav Aleshin, Marina Terzi, Jules Ghesquière

It is known that solid particles can move along vibrating surfaces due to the action of oscillating contact forces. The effect is used for sorting or transporting particles (granular mixtures or powders) in food and pharmaceutical industries. Future applications can include actuating micro-devices…

Sex-specific effects of different diets inducing MAFLD and treatment with the PPARα agonist elafibranor

I. Raho, R. Bertrand, J. Vicogne, A. Abderrahmani, C. Magnan, C. Cruciani-Guglielmacci

Background and aims: Metabolic associated fatty liver disease (MAFLD) is a liver disease characterized by fat accumulation and is often associated with obesity and type 2 diabetes. Recent studies suggest that sex may influence disease progression, although the underlying mechanisms remain unclear.…

Adhesion at the glass/metal interface probed by Brillouin oscillations in colored picosecond acoustics

Arnaud Devos

Glass is a common material already employed in everyday applications, which has gained considerable interest for electronic components, due to its attractive electrical, physical, and chemical properties, as well as its prospects for a cost-efficient solution. Adhesion of thin metal film on glass…

Point-of-Care Applicability of Graphene-Based Field Effect Transistors upon Modification with a Pyrene-Tagged Antifouling Copolymer: Application for cTnI Sensing in Blood

Rupali Bagale, Manova Santhosh Yesupatham, Abdellah Hambli, Subhankar Sahu, Christophe Ritzenthaler, Mandana Amiri, Sandro Spagnolo, Anna Kálosi, Francesco Basini, Henri Happy, Rabah Boukherroub, Wolfgang Knoll, Tibor Hianik, Eva Majková, Peter Šiffalovič, Roberto Corradini, David Montaigne, Eloise Woitrain, Adriana Hvizdošová Annušová, Sabine Szunerits

Field-effect transistors (FETs) are an integrated part of various electronic products and play an irreplaceable role in modern-day bioelectronics and biosensors. The electronic performance of FET-based sensors is intrinsically correlated with the choice of the sensing layer, with graphene being one…

Low-temperature cotunneling electron transport in photoswitchable molecule-nanoparticle networks.

Yannick Viero, David Guérin, Dominique Vuillaume

We report the temperature-dependent (4.2 - 300 K) electron transport properties (current-voltage) of photo-switchable two-dimensional arrays of gold nanoparticles (10 nm in diameter) functionalized by azobenzene derivatives. Under UV-light irradiation at 4.2 K, the azobenzene moieties are switched…

Advancing medical question answering with a knowledge embedding transformer

Xiang Zhu, Mustaqeem Khan, Abdelmalik Taleb-Ahmed, Alice Othmani

Efficient medical question answering is essential for better patient care. Despite progress since Eliza (1966), even advanced LLMs (e.g., GPT-4) struggle with medical data. This study presents a system combining knowledge embedding and transformers. It includes a knowledge understanding layer and…
