A General Framework for Generative Self-supervised Learning in Non-invasive Estimation of Physiological Parameters Using Photoplethysmography

This feed contains multiple arXiv preprints (April 28, 2026) with several papers that have security and dual‑use relevance. Notable items: (1) “Structural Limits of Soft Fusion in Multi‑Warden Covert Communication” demonstrates that soft fusion detection by a Fusion Center provides limited advantage against covert transmitters and jammers, including closed‑form FC thresholds and game‑theoretic equilibria—implications for covert comms, detection infrastructure design, and adversary/defender tradeoffs. (2) “Applied AI‑Enhanced RF Interference Rejection” presents transformer‑based interference-m它
