Cooperative Transmission for a Vector Gaussian Parallel Relay Network

open access: yes, 2009
In this paper, we consider a parallel relay network where two relays cooperatively help a source transmit to a destination. We assume the source and the destination nodes are equipped with multiple antennas. Three basic schemes and their achievable rates

Review of Organic Persistent Phosphors: Classifications by Material Forms, Applications, and Mechanisms

open access: yesAdvanced Optical Materials, Volume 14, Issue 4, 27 January 2026.
Persistent luminescence (PersL), or afterglow, is the phenomenon of light emission that continues long after the excitation source is removed. This review systematically covers the historical development and major material forms of organic PersL materials, detailing their operating principles, mechanisms, and typical applications.
