SPARK-IL: Spectral Retrieval-Augmented RAG for Knowledge-driven Deepfake Detection via Incremental Learning

Hessen Bougueffa Eutamene, Abdellah Zakaria Sellam, Abdelmalik Taleb-Ahmed, Abdenour Hadid

Detecting AI-generated images remains a significant challenge because detectors trained on specific generators often fail to generalize to unseen models; however, while pixel-level artifacts vary across models, frequency-domain signatures exhibit greater consistency, providing a promising…

0.53 mΩ.cm 2 /592 V High Breakdown Voltage GaN-on-Sapphire Schottky Diodes Without Edge Termination

Hugo Bouillaud, Beatriz Orfao, Etienne Okada, Yannick Roelens, Malek Zegaoui, Mohammed Zaknoune

In this letter, we report high-performance Pt/GaN quasi-vertical Schottky barrier diodes on sapphire substrate. With a 5 μm drift layer and a highly controlled fabrication process, the devices demonstrate an extremely low on-resistance of 0.53 mΩ.cm² while exhibiting a high breakdown voltage of 592…

Far-Field Terahertz Spectroscopy of a Subwavelength Single Planar Meta-Atom

Surya Revanth Ayyagari, Simonas Indrišiūnas, Guillaume Ducournau, Vytautas Janonis, Irmantas Kašalynas

Accurate measurements of light-matter interactions at subwavelength scales are critical for advancing nanophotonic and quantum optical technologies. In this paper, we present the far-field terahertz (THz) spectroscopy of a single planar meta-atom of subwavelength dimensions embedded within a square…

0.2-<i>μ</i>m InP/GaAsSb DHBT Transferred on Si-HR With 28 mW/<i>μ</i>m² at 94 GHz

Abdelmalek Zemour, Malek Zegaoui, Christophe Coinon, Yannick Roelens, Etienne Okada, Pascal Chevalier, Mohammed Zaknoune

We present 94 GHz large-signal load-pull measurements of a transferred InP/GaAsSb double heterojunction bipolar transistor fabricated on a high-resistivity silicon (Si-HR) substrate. The characterized device features an emitter area of 0.19 × 8.9 µm 2 . Biased for highest power, an output power of…

Plant- and Microalgae-Based Biotechnological Strategies for Affordable and Non-Invasive Delivery of Antidiabetic Peptides

Thibault Boscart, Alexandre Barras, Valérie Plaisance, Valérie Pawlowski, Emerson Giovanelli, Muriel Bardor, Christophe D’hulst, Amar Abderrahmani

The prevalence of diabetes and its worldwide co-morbidities is escalating. Therefore, the number of users of therapeutic peptides including insulin analogs and glucagon-like peptide 1 receptor agonists (GLP-1RAs), will unavoidably increase in the coming years. However, access to these two…
