Automated Differentiation of Oral Red‐White Lesions: An Interpretable Deep Learning Approach Combining Ensemble Architectures and Saliency Maps

Clinical and Experimental Dental Research, Volume 12, Issue 4, August 2026.
ABSTRACT Introduction Oral Potentially Malignant Disorders (OPMDs), including Leukoplakia and Erythroplakia, carry significant risks of malignant transformation. Early differentiation from confounding inflammatory conditions like Oral Lichen Planus (OLP) and Candidiasis is critical yet challenging due to visual similarities.

CRUSH: A New Cryptographic Hash Function using Iterated Halving Technique

, 2004
. Most of the currently accepted designs for cryptographic hash functions are in the style of a block cipher in feed-forward mode. With increasing interest in all forms of cryptanalysis, this limited choice might become a single point of failure in ...

Secure Decentralized Key Relaying via Random Walks in Dynamic Semi‐Trusted QKD Networks

Advanced Quantum Technologies, Volume 9, Issue 8, August 2026.
Quantum Key Distribution (QKD) provides point‐to‐point, information‐theoretically secure session keys, but distance limitations require trusted relays between remote parties. Can quantum keys be relayed without trusting every intermediate node or depending on a central controller?
