A versatile microfluidic electrochemical platform for diffusion-controlled, quasi-one-dimensional interfacial studies

Shreyanshu Agrawal, Alexander Saperstein, Farzam Zoueshtiagh, Ranga Narayanan, Kirk Ziegler

A quasi-one-dimensional microfluidic electrochemical platform suppresses convection through microscale confinement and eliminates electric field singularities through a dielectric overhang that shields the top surface of the electrode.

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…
