Using a sample of optically-selected quasars from the Sloan Digital Sky Survey, we have determined the radio-loud fraction (RLF) of quasars as a function of redshift and optical luminosity. The sample contains more than 30,000 objects and spans a redshift range of 0 < z 6 5 and a luminosity range of −30 6 Mi < −22. We use both the radio-to-optical flux ratio (R parameter) and radio luminosity t...

From the perspective of quantum gravity research, since archetypal gravitational object, black hole, was accidentally found function as a thermodynamic system, it is certainly natural to suggest that secret may lie in analysis. Until now, not possible express fine-grained entropy hole using rules gravity. However, holes entropic information formula fills this gap by allowing semi-classical appr...

Saccades bring objects of interest onto the fovea for high-acuity processing. Saccades to rewarded targets show shorter latencies that correlate negatively with expected motivational value. Shorter latencies are also observed when the saccade target is relevant for a perceptual discrimination task. Here we tested whether saccade preparation is equally influenced by informational value as it is ...
