purpose: the goal of this study was to compare differences in the mean heterophoria and fusional amplitudes before and after photorefractive keratectomy (prk) for myopia. methods: in a prospective controlled study, myopic patients were treated with aspheric and wavefront-guided (personalized) prk. the manifest refraction, visual acuity, fusional amplitudes and heterophoria were evaluated preope...

The Stirling cycle and related terminology is defined. Selected contemporary research involving the cycle in environmentally friendly applications is cited. Three conventional engine configurations that utilize a reciprocating power piston and crank shaft (the Alpha, Beta, and Gamma) are characterized, in terms of minimum number of components, advantages, and disadvantages. A new type of Stirli...

Wildlife–aircraft collisions (wildlife strikes) with civilian and military aircraft pose notable risks and economic losses. The 4 military services within the U.S. Department of Defense maintain records regarding wildlife strikes with military aircraft. Although rotary-wing aircraft operations comprise important mission components within all 4 military services, no assessment of wildlife strike...

the pediatric risk of mortality (prism) score is a measure of illness severity based on abnormalities observed on bedside examination and laboratory assessment at pediatric intensive care unit (picu) admission to predict mortality probability. our study was performed on 205 patients who were admitted to picu of children’s medical center (cmc) over a period of 6 months.data were recorded prospec...

Patients with hemispatial neglect ('neglect') following a brain lesion show difficulty responding or orienting to objects and events on the left side of space. Substantial evidence supports the use of a sensorimotor training technique called prism adaptation as a treatment for neglect. Reaching for visual targets viewed through prismatic lenses that induce a rightward shift in the visual image ...

UNLABELLED The Pictorial Representation of Illness and Self Measure (PRISM) is a recently developed tool designed to measure the burden of suffering due to illness in a variety of patient populations. The purpose of the current study was to validate PRISM as a measure of suffering in patients with chronic non-cancer pain. Patients (n = 138) were recruited from 2 hospital pain clinics, where the...

The Tunable Activation Threshold hypothesis of T Cells is investigated through computational modelling of T cell signalling pathways. Modelling techniques involving the π-calculus and the PRISM model checker are presented, and are applied to produce a stochastic model of T cell signalling. Initial results which demonstrate tuning of T cells are presented.

VT (Viterbi training), or hard EM, is an efficient way of parameter learning for probabilistic models with hidden variables. Given an observation y , it searches for a state of hidden variables x that maximizes p(x , y | θ) by coordinate ascent on parameters θ and x . In this paper we introduce VT to PRISM, a logic-based probabilistic modeling system for generative models. VT improves PRISM in ...
