Multimodal Optical Imaging for Detection of Cervical Neoplasia
(2013-09-16)Despite being the most preventable cancer, cervical cancer remains the third leading cause of cancer death worldwide. Over 85% of cervical cancer incidence and mortality occurs in low-resource countries where screening ... -
Multimodal snapshot spectral imaging for oral cancer diagnostics: a pilot study
(2013)Optical imaging and spectroscopy have emerged as effective tools for detecting malignant changes associated with oral cancer. While clinical studies have demonstrated high sensitivity and specificity for detection, current ... -
Multinuclei coherent effects on the widths and energy shifts on low energy neutron resonance
(1993)The exponentially decaying semi-stationary states of an assembly of identical classical radiators can have decay rates and resonant frequencies significantly different from that of an isolated radiator. These coherent ... -
Multioffset Inversion by Differential Semblance Optimization
(1990-12)A still-unresolved problem in reflection seismology is the estimation of wave velocities directly from waveform data, bypassing expensive manual steps such as event-picking in before-stack data. This paper suggests a ... -
Multiparameter adjoint tomography of the crust and upper mantle beneath East Asia: 1. Model construction and comparisons
(2015)We present a 3-D radially anisotropic model of the crust and mantle beneath East Asia down to 900 km depth. Adjoint tomography based on a spectral element method is applied to a phenomenal data set comprising 1.7 million ... -
Multiparameter inversion and energy source estimation for a reflection seismic experiment
(1995)Reflection seismologists illuminate the subsurface by introducing energy into the ground. These propagating waves encounter heterogeneities in the subsurface material and are partly reflected back up to the surface where ... -
Multiparameter Inversion and Energy Source Estimation for a Reflection Seismic Experiment
(1995-05)Reflection seismologists illuminate the subsurface by introducing energy into the ground. These propagating waves encounter heterogeneities in the subsurface material and are partly reflected back up to the surface where ... -
Multiparticle Optical and Thermal Effects in Illuminated Solutions of Plasmonic Nanoparticles
(2014-10-22)Plasmonic nanoparticles are found in a number of applications as efficient converters of optical energy into heat, e.g. cancer therapy of nanoparticle-laden tumors. More recently, aqueous solutions of plasmonic nanoparticles ... -
Multiphase unsaturated zone contaminant transport model for source term definition in ground water
(1991)A multiphase unsaturated zone contaminant transport (MUCT) model has been developed to simulate the simultaneous vertical flow of water and a second immiscible fluid in unsaturated porous media. The model couples multiphase ... -
Multiphysics model of a cardiac myocyte: A voltage-clamp study
(2013-07-24)We develop a composite multiphysics model of excitation-contraction coupling for a rat ventricular myocyte under voltage clamp (VC) conditions to: (1) probe mechanisms underlying the response to Ca2+-perturbation; (2) ... -
Multiphysics model of a rat ventricular myocyte: A voltage-clamp study
(2012)Background: The objective of this study is to develop a comprehensive model of the electromechanical behavior of the rat ventricular myocyte to investigate the various factors influencing its contractile response. Methods: ... -
Multiple access schemes over multipath fading channels
(1998-10-20)We compare the performance of different accessing schemes for communication over an additive white Gaussian noise multiple access channel with multipath fading. We assume that only the receiver can track the channel ... -
Multiple Basis Wavelet Denoising using Besov Projections
(1999-10-01)Wavelet-based image denoising algorithm depends upon the energy compaction property of wavelet transforms. However, for many real-world images, we cannot expect good energy compaction in a single wavelet domain, because ... -
Multiple choice: Literary racial formations of mixed race Americans of Asian descent
(2001)This dissertation reassesses key paradigms of Asian American literary studies in the interest of critically accounting for the cultural productions of mixed race Asian Americans. Over the last twenty years, Asian American ... -
Multiple early Eocene hyperthermal events: Their lithologic expressions and environmental consequences
(2009)A gradual rise in Earth's surface temperature marks a transition from the late Paleocene to the early Eocene ca. 58-51 Ma. Paleocene/Eocene boundary (∼55.5 Ma) sediments deposited in the midst of this slow warming ubiquitously ... -
Multiple event triggers in linear covariance analysis for orbital rendezvous
(2010)Linear covariance analysis is a powerful tool for spacecraft rendezvous analysis and design. This methodology is capable of generating results which compare well with the results of a Monte Carlo simulation while requiring ... -
MULTIPLE FREQUENCY BACKSCATTER OBSERVATIONS OF HEATER-INDUCED FIELD-ALIGNED STRIATIONS IN THE AURORAL E REGION (IONOSPHERE, MODIFICATION)
(1985)In September 1983 a series of HF ionospheric modification exper- iments were conducted in Scandinavia using the heating facility near Tromso, Norway. The purpose of these experiments was to examine the mechanisms by which ... -
Multiple invasions: invader interactions and multiple anthropogenic factors in wetland communities
(2015-10-22)Ecosystems invaded by one invader often contain abundant populations of other invaders. This may reflect facilitative invader interactions, common response to anthropogenic factors (nutrient enrichment and/or climate ... -
Multiple isomers of carbon(60)hydrogen(36): The products of the birch reduction of carbon(60)
(2000)The product mixture of the lithium Birch reduction of C60 is analyzed. C60H36 is identified as the major product; C60H32, C60H38 and C60H 40 are identified as minor products. The product mixture is separated into four ... -
Multiple Mobilities: Race, Capital, and South Asian Migrations to and Through Houston
(2013-09-16)The Immigration and Nationality Act of 1965 proved to be a watershed that altered the demographic composition of the United States in unexpected and unprecedented ways. Immigrants from India and Pakistan (part of South ...
