Hybrid Threshold Denoising Framework Using Singular Value Decomposition for Side-Channel Analysis Preprocessing

Yuanzhen Wang, Hongxin Zhang, Xing Fang, Xiaotong Cui, Wenxu Ning, Danzhi Wang, Fan Fan, Lei Shu

A device can reveal its encryption key without saying a word. Tiny electrical traces carry clues about the secret, but noise can bury them before anyone can read them. What if the best way to improve an AES side-channel attack is not a new attack at all, but a smarter way to clean the measurements first? This paper uses singular value decomposition to keep useful leakage while suppressing noise.

Methodological issues of the electronic health records’ use in the context of epidemiological investigations, in light of missing data: a review of the recent literature

Thomas Tsiampalis, Demosthenes B. Panagiotakos

Medical records can help prevent disease and improve treatment—even when parts of a patient’s story are missing. But the way those blank spaces are handled can quietly change the conclusion doctors and researchers reach. Electronic health records can improve prevention, treatment, research, and even pandemic response—but the review finds that missing data are often handled inconsistently, leaving important uncertainty behind.
