OBJECTIVES To validate the PRISM (Pictorial Representation of Illness and Self Measure) tool, a novel visual instrument, for the assessment of health-related quality of life in dermatological inpatients compared with the Dermatology Life Quality Index (DLQI) and the Skindex-29 questionnaires and to report qualitative information on PRISM. DESIGN In an open longitudinal study, PRISM and Skinde...

Vertical fusional vergence (VFV) normally compensates for slight vertical heterophorias. We employed magnetic resonance imaging to clarify extraocular muscle contributions to VFV induced by monocular two-prism diopter (1.15°) base-up prism in 14 normal adults. Fusion during prism viewing requires monocular infraduction. Scans were repeated without prism, and with prism shifted contralaterally. ...

PURPOSE To evaluate the effect of acrylic refractive prism and Fresnel membrane prism on stereoacuity in intermittent exotropia. MATERIALS AND METHODS Stereoacuities of fifty-two patients (mean age, 12.4 years; range 6 to 45 years) with intermittent exotropia were measured using the Titmus and TNO stereotests, while they wore prisms of varying power on nonfixating eye or evenly on each eye. ...

A data-graph computation — popularized by such programming systems as Pregel, GraphLab, Galois, Ligra, PowerGraph, and GraphChi — is an algorithm that iteratively performs local updates on the vertices of a graph. During each round of a data-graph computation, a user-supplied update function atomically modifies the data associated with a vertex as a function of the vertex’s prior data and that ...

Analysis of inconsistencies in multi-year gridded quantitative precipitation estimate over complex terrain and its impact on hydrologic modeling" (2012). s u m m a r y It is common that bias trends of long term precipitation data change over time due to various factors such as gauge relocation and changes in data processing methods. Temporal consistency of this error characteristic of precipita...

PURPOSE Although the treatment of symptomatic convergence insufficiency (CI) with base-in (BI) prism in adults has a strong theoretical foundation, there have been very few studies addressing its efficacy. The purpose of this study was to investigate whether the application of BI prism, using a novel progressive addition lens design which incorporates BI prism in the near portion only, could he...

A recent emergence of small, resource-constrained, and highlymobile computing platforms presents numerous new challenges for software developers. We refer to development in this new setting as programming-in-thesmall-and-many (Prism). This paper provides a description and evaluation of a middleware intended to support software architecture-based development in the Prism setting. The middleware,...

BACKGROUND Whether prism, especially base-up prism, affects the area of the retina used for fixation in a patient with central scotoma has been a controversial subject for 35 years. Our pilot study employed microperimetry to evaluate the effect of base-up prism on the fixation locus, or preferred retinal locus (PRL), in subjects with central scotoma. METHODS We used a microperimeter to assess...

In this paper, we present our work on extending the probabilistic model checking tool PRISM with Grid computing capabilities. PRISM is a tool for the verification and analysis of large, probabilistic models, a process which involves numerical solution techniques. Like most verification tools, PRISM can be very resource intensive and will benefit greatly from parallelisation efforts. Grid comput...
