A Tensor-Based Modulation Scheme with Hybrid Optimization for Unsourced Random Access

Ala Baccar, Alexis Decurninge, Sofiane Kharbech, Rima Khouja, Eric Pierre Simon, Joumana Farah

<div><p>This paper extends the idea of tensor-based modulation (TBM) for unsourced random access by introducing a new small sub-constellation, enabling a hybrid continuous-discrete optimization approach on the tensor factors. This approach enhances the detection process and extends the…

Drying Behavior of Flax Stems at Different Degrees of Dew Retting Under Simulated Rainfall: Implications for Smart Agriculture and Sensor Development

Ali Reda, Lionel Buchaillot, Steve Arscott

Dew retting of flax stems is a key agricultural process which facilitates fiber extraction from parent stems. If sensors are to be developed to monitor the degree of retting for optimal fiber extraction, then stem characteristics such as water uptake and loss need to be accurately known. Here, the…

Ultra-thin normal-shear-coupled meta-barrier for low-frequency underwater sound insulation

Marco Miniaci, Vinicius Fonseca Dal Poggetto

Underwater noise pollution from anthropogenic activities, such as offshore oil and gas exploration, poses significant threats to marine life. A common mitigation strategy involves enclosing primary noise sources within physical barriers to reduce noise levels in surrounding environments. Underwater…

Recueil de communications école d'hiver 2025 GDR ARCHI-META - DN METACMED

Marco Miniaci, Giuseppe Rosi, Nicolas Auffray, Cédric Bellis, Christelle Combescure, Justin Dirrenberger, Kerem Ege, Muamer Kadic, Fabrice Lemoult, Bruno Morvan, Vincent Pagneux, Julien Poittevin, Martin Poncelet

The last 20 years have seen a remarkable growth in scientific interest in (elastic and mechanical) metamaterials. One of the reasons for this is the great potential that this subject area has in itself as a “link between different disciplines”, particularly acoustics and solid mechanics. In…

Brain‐Inspired Polymer Dendrite Networks for Morphology‐Dependent Computing Hardware

Corentin Scholaert, Yannick Coffinier, Sébastien Pecqueur, Fabien Alibart

Process variation is always a challenge to mitigate in electronics. This especially holds true for organic semiconductors, where reproducibility concerns hinder industrialization. Challenging this concept, it shows AC-electropolymerization to be a powerful platform for the development of morphology…
