Spatial frequency adaptation can enhance contrast sensitivity.
A~~ct-Adaptation to a high-contr~t sinusoid& ium~nan~ grating produces a temporary, bandlimited loss in sensitivity centered around the adaptation frequency. The decrease appears to be both narrower and more symmetrical than earlier reports suggest. The effect falls to zero by f f 1 octave and is not reliably present from f f 1 octave to f k 2 octaves. Enhancement of contrast sensitivity occurs...
متن کاملCharacterizing the spatial-frequency sensitivity of perceptual templates.
Filtered external noise has been an important tool in characterizing the spatial-frequency sensitivity of perceptual templates. Typically, low-pass- and/or high-pass-filtered external noise is added to the signal stimulus. Thresholds, the signal energy necessary to maintain given criterion performance levels, are measured as functions of the spatial-frequency passband of the external noise. An ...
متن کاملSensitivity of Human Leukemic Cells to Carvedilol
Background and Objective: Carvedilol, a non-specific β-blocker, has been used for treatment of hypertension, stroke and congestive heart failure. The therapeutic effects of β blockers in cancer patients have been shown. Carvedilol has considerable anti-inflammatory, anti-tumor and anti-angiogenic properties. In this study, the effects of carvedilol on proliferation of human U937 and Molt-4 leuk...

15 صفحه اولSensitivity Analysis of Spatial Sampling Designs for Optimal Prediction
In spatial statistic, the data analyzed which is correlated and this correlation is due to their locations in the studied region. Such correlation that is related to distance between observations is called spatial correlation. Usually in spatial data analysis, the prediction of the amount of uncertain quantity in arbitrary 4locations of the area is considered according to attained observations ...
