We investigated how visual noise in the initial estimate of target location affects precision for rapid pointing. Visual localization thresholds (an error measure) rise systematically with eccentricity, doubling at eccentricities of a degree or less. Previous work, which we confirmed, has shown that the precision of pointing, measured by the standard deviation, to a single isolated target is re...

We consider the problem of clustering (or reconstruction) in the stochastic block model, in the regime where the average degree is constant. For the case of two clusters with equal sizes, recent results [MNS13, Mas14, MNS14] show that reconstructability undergoes a phase transition at the Kesten-Stigum bound of λ 2 d = 1, where λ2 is the second largest eigenvalue of a related stochastic matrix ...

Aim: The primary aim of this study was to find if there is any correlation between the corneal radius of curvature and its eccentricity. Method: 45 subjects participated in this study, 24 emmetropes, 18 myopes and three hyperopes. All subjects were free of ocular abnormalities and had no media opacities. All the subjects had normal ocular health and good visual acuity of 1.0 or better for both ...

Perception of constant motion has been extensively studied both psychophysically and physiologically, but the human ability to detect dynamic changes in motion, such as rapid speed changes, is only poorly characterized and understood. Yet, perception and representation of such dynamic changes is of strong behavioral relevance, as illustrated by their potential for attentional capture. In the pr...

This study presents a new nanotechnology application involving an ITO thin-film removal reuse process using an eccentric-form negative electrode, offering a fast removal rate from the surface of liquid crystal displays (LCDs). For the precision removal process, a small amount of eccentricity of the negative electrode or a higher rotational speed of the negative electrode corresponds to a higher...

the center (periphery) of a graph is the set of vertices with minimum (maximum)eccentricity. in this paper, the structure of centers and peripheries of some classes ofcomposite graphs are determined. the relations between eccentricity, radius and diameterof such composite graphs are also investigated. as an application we determinethe center and periphery of some chemical graphs such as nanotor...

The contrast sensitivity of the human eye has been measured as a function of eccentricity. The stimulus used was a sine-wave grating with a fixed height of 5’. in a surround of luminance that equals the average stimulus luminance. The measurements were carried out with stimulus width as the independent variable. The “local’. sensitivity for gratings was found to decrease monotonically with incr...

This report is a review of Darwin’s classical theory of bodily tides in which we present the analytical expressions for the orbital and rotational evolution of the bodies and for the energy dissipation rates due to their tidal interaction. General formulas are given which do not depend on any assumption linking the tidal lags to the frequencies of the corresponding tidal waves (except that equa...
