PURPOSE To compare the visual acuity outcomes between 2 target locations for corneal inlay implantation with concurrent laser in situ keratomileusis (LASIK) to compensate for presbyopia. SETTING Shinagawa LASIK Center, Tokyo, Japan. DESIGN Retrospective cohort study. METHODS Bilateral LASIK was performed simultaneously with inlay implantation in the nondominant eye. The preoperative and 6...

The range space of dynamic textures spans spatiotemporal phenomena that vary along three fundamental dimensions: spatial texture, spatial texture layout, and dynamics. By describing each dimension with appropriate spatial or temporal features and by equipping it with a suitable distance measure, elementary distances (one for each dimension) between dynamic texture sequences can be computed. In ...

We show how to learn aMahanalobis distance metric for k-nearest neighbor (kNN) classification by semidefinite programming. The metric is trained with the goal that the k-nearest neighbors always belong to the same class while examples from different classes are separated by a large margin. On seven data sets of varying size and difficulty, we find that metrics trained in this way lead to signif...

background: cross- sectional tomograms have been used for optimal pre-operative planning of dental implant placement. the aim of the present study was to assess the accuracy of cone beam computed tomography (cbct) measurements of specifi c distances around the mandibular canal by comparing them to those obtained from multi-slice computed tomography (msct) images. materials and methods: ten hemi...

Electrical stimulation of the median nerve at the wrist may elicit a blink reflex [hand blink reflex (HBR)] mediated by a neural circuit at brain stem level. As, in a Sherringtonian sense, the blink reflex is a defensive response, in a series of experiments we tested, in healthy volunteers, whether and how the HBR is modulated by the proximity of the stimulated hand to the face. Electromyograph...

We propose a new online learning algorithm which provably approximates maximum margin classifiers with bias, where the margin is defined in terms of p-norm distance. Although learning of linear classifiers with bias can be reduced to learning of those without bias, the known reduction might lose the margin and slow down the convergence of online learning algorithms. Our algorithm, unlike previo...

The study proposed to evaluate the feasibility of predicting sphincter-sparing surgery (SSS) preoperatively in low-middle rectal cancer by using magnetic resonance (MR).The study included both retrospective and prospective design. In the retrospective design, the distance from lower edge of tumor to upper margin of the internal sphincter (Dis1) and distance to anal verge (Dis2) were measured on...

Purpose : A new method of calibration of the displacement of the cornea1 reflex in relation to the angular deviation was carried out on a population of normal subjects. Methods : The position of the cornea1 reflex was studied in 15 normal adult subjects, emmetropic and orthophoric. Each eye, photographed individually, was situated perpendicularly at the zero of a tangential scale. Slides taken ...
