Purpose To develop an objective refraction formula based on the ocular wavefront error (WFE) expressed in terms of Zernike coefficients and pupil radius, which would be an accurate predictor of subjective spherical equivalent (SE) for different pupil sizes. Methods A sphere is fitted to the ocular wavefront at the center and at a variable distance, t. The optimal fitting distance, topt, is ob...

We study a topological string description of the c < 1 non-critical string whose matter part is defined by the time-like linear dilaton CFT. We show that the topologically twisted N = 2 SL(2, R)/U(1) model (or supersymmetric 2D black hole) is equivalent to the c < 1 non-critical string compactified at a specific radius by comparing their physical spectra and correlation functions. We examine an...

Consider a square random matrix with independent and identically distributed entries of mean zero unit variance. We show that as the dimension tends to infinity, spectral radius is equivalent root in probability. This result can also be seen convergence support circular law theorem under optimal moment conditions. In proof we establish reciprocal characteristic polynomial analytic function outs...

five cases of giant cell tumor of the lower end of radius are reported. three of the patients were women and two were men, the youngest of the patients was 18 years old and oldest 37 years. en bloc resection followed by reconstructive procedures were performed in three of the cases with good results.

PURPOSE To study the distribution of spherical equivalent refraction and ocular biometric parameters in a young Australian population. METHODS Noncontact methods were used to examine ocular dimensions and cycloplegic autorefraction in a stratified random cluster sample of year 1 Sydney school students (n = 1765), mean age 6.7 years (range, 5.5-8.4 years). Repeated measures of axial length, an...

BACKGROUND Symptomatic extensor tendon irritation is a frequent complication in volar plate osteosynthesis of distal radius fractures. It is typically caused by dorsal screw protrusion and overdrilling of the dorsal cortex. The use of self-drilling locking screws (SDLS) could overcome both causes. The practical applicability of SDLS depends on two prerequisites: (1) the feasibility of preoperat...

introduction: distal radius fractures are a common traumatic injury, particularly in the elderly population. in the present study we examined the effectiveness of ultrasound guidance in the reduction of distal radius fractures in adult patients presenting to emergency department (ed). methods: in this prospective case control study, eligible patients were adults older than 18 years who presente...

PURPOSE The aim of this study was to compare the relation between differently measured sports activities (metabolic equivalent [MET] and peak strain score) and distal radius bone mineral density in college-aged women. METHODS Lifetime sports activity was scored in two different ways: 1) a sports activity score by multiplying the intensity (METs) and duration and 2) a sports activity score by ...
