Measuring large-scale structure with quasars in narrow-band filter surveys [PDF]

, 2012
We show that a large-area imaging survey using narrow-band filters could detect quasars in sufficiently high number densities, and with more than sufficient accuracy in their photometric redshifts, to turn them into suitable tracers of large-scale ...

LUGOL’S IODINE CHROMOENDOSCOPY VERSUS NARROW BAND IMAGE ENHANCED ENDOSCOPY FOR THE DETECTION OF ESOPHAGEAL CANCER IN PATIENTS WITH STENOSIS SECONDARY TO CAUSTIC/CORROSIVE AGENT INGESTION

Arquivos de Gastroenterologia, 2017
BACKGROUND The diagnosis of corrosion cancer should be suspected in patients with corrosive ingestion if after a latent period of negligible symptoms there is development of dysphagia, or poor response to dilatation, or if respiratory symptoms develop in

A Spectral-Scanning Magnetic Resonance Imaging (MRI) Integrated System [PDF]

, 2008
An integrated spectral-scanning magnetic resonance imaging (MRI) technique is implemented in a 0.12μm SiGe BiCMOS process. This system is designed for small-scale MRI applications with non-uniform and low magnetic fields.

The Narrow-band Ultraviolet Imaging Experiment for Wide-field Surveys (NUVIEWS)-I: Dust scattered continuum [PDF]

, 1999
We report on the first results of the Narrow-band Ultraviolet Imaging Experiment for Wide-field Surveys (NUVIEWS), a sounding rocket experiment designed to map the far-ultraviolet background in four narrow bands.

Narrow-band imaging of NGC 7026 [PDF]

Symposium - International Astronomical Union, 1997
NGC 7026 is one of the most remarkable bipolar planetary nebulae in the northern sky. There is an increasing interest in sources of this kind, as they indicate that anisotropic outflow phenomena play a significant role in the final evolutionary stages of massive stars. To investigate the spatial distribution of the excitation conditions in this nebula,

Diagnostic Value of Narrow Band Imaging in Diagnosing Nasopharyngeal Carcinoma

Althea Medical Journal, 2017
Background: Carcinoma is the most common tumor in nasopharynx. Endoscopy is used to determine the presence of lesions suspected of malignancy. Narrow Band Imaging is an endoscopic technique that uses narrow–band spectrum as a filter to determine any ...

Lyman Alpha Emitters at Redshift 5.7 in the COSMOS Field [PDF]

, 2007
We present results from a narrow-band optical survey of a contiguous area of 1.95 deg^2, covered by the Cosmic Evolution Survey (COSMOS). Both optical narrow-band (lambda_c = 8150 AA and Delta_lambda = 120 AA) and broad-band (B, V, g', r', i', and z ...

A contribution to the selection of emission-line galaxies using narrow-band filters in the optical airglow windows [PDF]

, 2007
Emission line galaxies are an invaluable tool for our understanding of the evolution of galaxies in the Universe. Imaging of deep fields with narrow-band filters allows not only the selection of these objects, but also to infer the line flux and the ...
