Optimized approach to decision fusion of heterogeneous data for breast cancer diagnosis.
(Med Phys, 2006-08)
As more diagnostic testing options become available to physicians, it becomes more difficult to combine various types of medical information together in order to optimize the overall diagnosis. To improve diagnostic performance, ...
Comparative performance of multiview stereoscopic and mammographic display modalities for breast lesion detection.
(Med Phys, 2011-04)
PURPOSE: Mammography is known to be one of the most difficult radiographic exams to interpret. Mammography has important limitations, including the superposition of normal tissue that can obscure a mass, chance alignment ...
Coordinated analysis of delayed sprites with high-speed images and remote electromagnetic fields
(Journal of Geophysical Research Atmospheres, 2008-10-27)
Simultaneous measurements of high-altitude optical emissions and magnetic fields produced by sprite-associated lightning discharges enable a close examination of the link between low-altitude lightning processes and high-altitude ...
Harmonic source wavefront aberration correction for ultrasound imaging.
(J Acoust Soc Am, 2011-01)
A method is proposed which uses a lower-frequency transmit to create a known harmonic acoustical source in tissue suitable for wavefront correction without a priori assumptions of the target or requiring a transponder. The ...
Bayesian Spatial Quantile Regression.
(J Am Stat Assoc, 2011-03)
Tropospheric ozone is one of the six criteria pollutants regulated by the United States Environmental Protection Agency under the Clean Air Act and has been linked with several adverse health effects, including mortality. ...
A study of the aeroelastic behavior of flat plates and membranes with mixed boundary conditions in axial subsonic flow
(Collection of Technical Papers - AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics and Materials Conference, 2011-12-01)
In support of the noise reduction targets for future generations of transport aircraft, as set forth by NASA, the fundamental aeroelastic behavior of trailing edge flap technology was explored. Using a plate structural model ...
(Opt Express, 2009-07-20)
Compressive sampling enables signal reconstruction using less than one measurement per reconstructed signal value. Compressive measurement is particularly useful in generating multidimensional images from lower dimensional ...
Plate-specific gain map correction for the improvement of detective quantum efficiency in computed radiography.
(Med Phys, 2012-03)
PURPOSE: The purpose of this work is to improve the noise power spectrum (NPS), and thus the detective quantum efficiency (DQE), of computed radiography (CR) images by correcting for spatial gain variations specific to individual ...
Mechanical constraints enhance electrical energy densities of soft dielectrics
(APPLIED PHYSICS LETTERS, 2011-10-24)
Deposition of silver nanoparticles in geochemically heterogeneous porous media: predicting affinity from surface composition analysis.
(Environ Sci Technol, 2011-06-15)
The transport of uncoated silver nanoparticles (AgNPs) in a porous medium composed of silica glass beads modified with a partial coverage of iron oxide (hematite) was studied and compared to that in a porous medium composed ...
