A new study reveals that Srinivasa Ramanujan’s century-old formulas for calculating pi unexpectedly emerge within modern theories of critical phenomena, turbulence, and black holes. In school, many of ...
Reversible Data Hiding in Encrypted Medical Images Based on Huffman Tree Coding and Count-Encryption
Abstract: Reversible data hiding in encrypted images (RDHEI) has been recognized as an effective method for overcoming management difficulties within picture archiving and communication system (PACS).
Abstract: This article proposes a unified consensus algorithm with predefined-time convergence aimed at solving time-varying optimization problems based on multiagent systems under connected and ...
A team of researchers published a comprehensive study on November 20 analyzing over 192,000 reasoning traces from large language models (LLMs), revealing that AI systems rely on shallow, linear ...
