High-z Type Ia supernovae are expected to be gravitationally lensed by the foreground distribution of largescale structure. The resulting magnification of supernovae is statistically measurable, and the angular correlation of the magnification pattern directly probes the integrated mass density along the line of sight. Measurements of cosmic magnification of supernovae therefore complements gal...

Chronic obstructive pulmonary disease (COPD) is one of the leading causes of morbidity and mortality worldwide. COPD was under diagnosed in India, but is now recognized in 4-10 per cent of adult male population of India and several other Asian countries [1]. Spirometry is the accepted and standard for the diagnosis and assessment of severity of COPD. BODE index is a multidimensional grading sys...

BACKGROUND Previous reports assessing diagnostic skill using narrow-band imaging (NBI) and pit pattern analysis for colorectal polyps involved only highly experienced endoscopists. OBJECTIVE To evaluate diagnostic skills of less-experienced endoscopists (LEE group) for differentiation of diminutive colorectal polyps by using NBI and pit pattern analysis with and without magnification after an...

The digital radiographic process involves (a) the attenuation of x rays along rays forming an orthographic projection, (b) the detection of the radiation beam by a two-dimensional recording device, (c) the processing of detector signals to produce a digital image for presentation, and (d) the display of the digital image. The performance of the process is typically considered in terms of the ab...

PURPOSE The purpose of this pilot study was to evaluate the effect of magnification lenses on the indirect vision skills of dental hygiene students. METHODS This pilot study examined the accuracy and efficiency of dental hygiene students' indirect vision skills while using traditional safety lenses and magnification lenses. The sample was comprised of 14 students in their final semester of a...

Microlensing uses gravitational lensing of individual stars to detect planets. In a microlensing event, the light from one star, the “source”, is magnified by the gravitational field of another star, the “lens”. A microlensing event occurs when the paths of two stars on the sky pass very close to each other, typically less than 1′′ [An arcsecond (′′) is 1/3600th of a degree. It may be further d...

Powerful blue-light emitting dental curing lights are used in dental offices to photocure resins in the mouth. In addition, many dental personnel use magnification loupes. This study measured the effect of magnification loupes on the "blue light hazard" when the light from a dental curing light was reflected off a human tooth. Loupes with 3.5x magnification (Design for Vision, Carl Zeiss, and Q...
