Tensor-Based Modulation-Enabled Signaling for Massive Unsourced Random Access in Cell-Free Networks

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

This paper investigates the application of tensor-based modulation (TBM), an unsourced random access scheme, in a cell-free massive multiple-input multiple-output (MIMO) architecture. In this system, multiple access points (APs), connected to a central processing unit (CPU), collaboratively serve a...

Conflict-Aware Multimodal Fusion for Ambivalence and Hesitancy Recognition

Salah Eddine Bekhouche, Hichem Telli, Azeddine Benlamoudi, Salah Eddine Herrouz, Abdelmalik Taleb-Ahmed, Abdenour Hadid

Ambivalence and hesitancy (A/H) are subtle affective states where a person shows conflicting signals through different channels -- saying one thing while their face or voice tells another story. Recognising these states automatically is valuable in clinical settings, but it is hard for machines...

We present a molecular study combining Raman, infrared, and UV–visible absorption spectroscopy with density functional theory (DFT) calculations to investigate triphenylene and its iodinated derivative, 1,5,9-triiodotriphenylene. The results provide a detailed comparison of their vibrational and..., Des études à l'échelle moléculaire de spectroscopie Raman, infra-rouge et absorption UV-visible, basées sur des simulations en théorie de la fonctionnelle de la densité sur le triphénylène et le dérivé iodé 1,6,9 triiodotriphénylène. Les résultats donnent une comparaison précise des propriétés...

Interface-engineered vanadium-tungsten nitride nanolaminate thin films for high-performance micro-supercapacitors

Khac Huy Dinh, Kevin Robert, Jérémie Chaillou, Lydia Karmazin, Isabelle Roch-Jeune, Chiara Crivello, Marielle Huvé, David Troadec, Christophe Lethien, Pascal Roussel

Multicationic nitrides are emerging as a new class of high-performance electrode materials for microsupercapacitors (MSCs), yet their synthesis and structural control remain challenging. Here, we report the fabrication of VWN nanolaminates using reactive magnetron sputtering deposition method. The...

PCB-Based Hybrid Series/Corporate-Fed 4 × 4 D-Band Phased Array With Wide-Angle Scanning

Kamil Yavuz Kapusuz, Samuel Rimbaut, Siddhartha Sinha, Joris van Driessche, Ad Reniers, A. Bart Smolders, Pascal Szriftgiser, Guillaume Ducournau, Hendrik Rogier, Sam Lemey

Sixth generation (6G) wireless networks are envisioned to include aspects of energy footprint reduction (sustainability), besides those of network capacity and connectivity, at the design stage. This paradigm change requires radically new physical layer technologies. Notably, the integration of...

High-Sensitivity Love Wave SAW Sensors with Composite Guiding Layer and Phononic Crystal Cavity

A. Leschiutta, G. Eybert-Bouillier, Othmane Marbouh, O. Bou-Matar, V. Mortet, A. Talbi

In Love-wave-based biosensors, the most widely used architecture is the delay-line configuration, in which the sensing function is achieved by functionalizing the acoustic propagation path. This approach offers high robustness and compatibility with liquid-phase operation, making it particularly...

Development and validation of a 2D Mason model for ultrasonic transducer arrays: A simplified approach simulating crosstalk and dissipation mechanisms

Anouar Boujenoui, Abdelmajid Bybi, Hayat Reskal, Hassna Khalfi, Lahoucine Elmaimouni, Anne-Christine Hladky-Hennion

Piezoelectric elements arranged in 1D or 2D configurations are commonly used in ultrasonic transducer arrays for medical imaging and non-destructive testing (NDT) applications. These arrays are usually modeled using complex 2D or 3D numerical methods. Based on the equivalent circuit approach...
