By using violet backgrounds we selectively altered blue-cone sensitivity but found no change in flicker photometric sensitivity. This indicates that blue cones do not contribute to luminance as defined by flicker photometry.

PURPOSE The rodent retina does not exhibit a positive OFF-response in the electroretinogram (ERG), which makes it difficult to evaluate its OFF-pathway functions in vivo. We studied the rod-driven OFF pathway responses by using a dark-adapted 10-Hz flicker ERG procedure in mouse. MATERIALS AND METHODS Conventional ERGs and 10-Hz dark-adapted flicker ERGs were obtained in wild-type mice (C57BL...

To realize perceptual space constancy, the visual system compensates for the retinal displacement caused by eye movements. It has been reported that the compensation process does not function perfectly around the time of a saccade--a perisaccadic flash is systematically mislocalized. However, observations made with transient flash stimuli do not necessarily indicate a general perisaccadic failu...

OBJECTIVE Flicker light-induced retinal vasodilation may reflect endothelial function in the retinal circulation. We investigated flicker light-induced vasodilation in individuals with diabetes and diabetic retinopathy. RESEARCH DESIGN AND METHODS Participants consisted of 224 individuals with diabetes and 103 nondiabetic control subjects. Flicker light-induced retinal vasodilation (percentag...

Introduction:GaAsySb1-y/In0xGa1-xAs based III-V staggered hetero-junction Tunnel Field Effect Transistors were demonstrated with MOSFET-like high drive currents at low Vds [1], demonstrating feasibility of TFETs to scale supply voltage for future low power logic applications. More than 2x enhancement in Ion was demonstrated over the In0.7Ga0.3As homo-junction counterpart due to reduction in the...

How sensitive are viewers to changes in global image properties across saccades during active real-world scene perception? This question was investigated by globally increasing and/or decreasing luminance or contrast in photographs of real-world scenes across saccadic eye movements or during matched brief interruptions in a flicker paradigm. The results from two experiments demonstrated very po...

This paper deals with the solution of the issue of exceeding the permissible levels for long-term flicker effect Plt in industrial distribution systems. Flicker effect in distribution systems is often exceeded as a result of the connection of electric arc furnaces, which exhibits high variable electrical power in-take. The article shows the benefits of measures on the steel plants, the distribu...

UNLABELLED With strict fixation, a flickering disk presented in the peripheral retina rapidly appeared to lose contrast and stop flickering, owing to adaptation. Subjects measured this adaptation by continually adjusting the flicker amplitude of a peripherally viewed disk to hold it just at threshold. RESULTS (1) The contrast threshold for flicker increased logarithmically over time. (2) The ...

Previous research (e.g., Wong & Weisstein, 1984a, 1985) has shown that flickering stimuli appear to be more distant than nonflickering stimuli at the same physical distance. Given this relation between flicker and perceived depth, inappropriate constancy scaling theories predict that flickering stimuli should be perceived as larger than nonflickering ones. In contrast, links between flicker and...

Today we have powerful, feature-rich computer systems plagued by powerful, feature-rich malware. Current malware exploit the vulnerabilities that are endemic to the huge computing base that needs to be trusted to secure our private information. This thesis presents an architecture called Flicker that alleviates security-conscious developers from the burden of making sense out of this code base,...
