Multi‐Omics Integration for Advancing Glioma Precision Medicine
Annals of Clinical and Translational Neurology, Volume 13, Issue 1, Page 4-13, January 2026.ABSTRACT Gliomas are among the most malignant and aggressive tumors of the central nervous system, characterized by the absence of early diagnostic markers, poor prognosis, and a lack of effective treatments. Advances in high‐throughput technologies have facilitated a refined molecular classification of gliomas, incorporating genetic features. However,

A VLSI architecture design of VLC encoder for high data rate video/image coding [PDF]
ISCAS'99. Proceedings of the 1999 IEEE International Symposium on Circuits and Systems VLSI (Cat. No.99CH36349), 2003 An efficient architecture of variable length coding (VLC) is developed for recent multimedia applications, such as video and image compression. VLC plays a crucial part in these applications in that it provides a very effective coding gain. In this paper, we will describe an architecture design of VLC encoder. It can produce VLC codeword and amplitude,

PSO Algorithm on PAPR Reduction Performance of Asymmetrically Clipped Optical‐OFDM
Applied Computational Intelligence and Soft Computing, Volume 2026, Issue 1, 2026.This research presents a novel hybrid optimization framework combining artificial neural networks (ANN) and particle swarm optimization (PSO) to mitigate the high peak‐to‐average power ratio (PAPR) in asymmetrically clipped optical‐orthogonal frequency division multiplexing (ACO‐OFDM) systems. While conventional PTS effectively reduces PAPR, it suffers
