Chandra Survey of Nearby Galaxies: Testing the Accretion Model for Low-luminosity AGNs
Rui She, Luis C. Ho, Hua Feng +1
From a Chandra sample of active galactic nuclei (AGNs) in nearby galaxies, we find that for low-luminosity AGNs (LLAGNs), either the intrinsic absorption column density, or the fra…
A Switch to the Concern of User: Importance Coefficient in Utility Distribution and Message Importance Measure
Shanyun Liu, Rui She, Shuo Wan +2
This paper mainly focuses on the utilization frequency in receiving end of communication systems, which shows the inclination of the user about different symbols. When the average…
