We develop an approach to utilize anisotropic metamaterials to solve one of the fundamental problems of modern plasmonics--parasitic scattering of surface waves into free-space modes, opening the road to truly two-dimensional plasmonic optics. We illustrate the developed formalism on the examples of plasmonic refractor and plasmonic crystal, and discuss limitations of the developed technique an...

Pencil Grasp Pattern: How Critical is it to Functional Handwriting? Heidi D. Schwellnus Doctor of Philosophy Graduate Department of Rehabilitation Science University of Toronto 2012 This thesis reports the results of a large study to evaluate the kinetics of pencil grasp patterns in terms of speed and legibility of handwriting of children in Grade 4. Current clinical practice as recent as 2008 ...

Introduction Plenty of information about health is available on the Internet; however, quality and legibility are not always evaluated. Knowledge regarding orofacial functions can be considered important for the population because it allows proper stimulus, early diagnosis, and prevention of the oral myofunctional alterations during early infancy. Objective The aim was evaluate the quality, leg...

The purpose of this study was to quantify real-world highway sign reading behavior while driving at night. Sign reading behavior was assessed using traditional self-report augmented by an in-vehicle eye tracking system. Good agreement was found between eye movement data (last-look distance) and verbal report measures of sign legibility distance (r = 0.9). Significant reductions in legibility di...
