Decline of the Space Density of Quasars between z = 2 and z = 4
We define a new complete sample of 13 optically luminous radio quasars [MAB(1450 A) 25.7] with redshift 3.8 < z < 4.5, obtained by cross-correlating the Faint Images of the Radio Sky at Twenty cmExpand

An interactive perception-based model for characterization of display devices
TLDR
In this paper we introduce a novel and accurate characterization model to acquire the TRCs of the color channels of display devices without using a spectrophotometer, based only on human perception and interactive decisions. Expand
