Full-wave Nonlinear Inverse Scattering for Acoustic and Electromagnetic Breast Imaging.
(2012)
Acoustic and electromagnetic full-wave nonlinear inverse scattering techniques are explored in both theory and experiment with the ultimate aim of noninvasively mapping the material properties of the breast. There is ...
Exploring the Mechanics of Transcriptional Control through DNA Looping with Optical Tweezers.
(2010)
The interior of a cell is a crowded and constantly fluctuating environment, where DNA and other biomolecules are highly constrained and subject to various kinds of me-chanical forces. To unravel the role of mechanics in ...
Search for the Standard Model Higgs Boson in Associated Production with W Boson at the Tevatron.
(2010)
A search for the Standard Model Higgs boson in proton-antiproton collisions with center-of-mass energy 1.96 TeV at the Tevatron is presented in this dissertation. The process of interest is the associated production of W ...
An Experimental Investigation of Reacting and Nonreacting Coaxial Jet Mixing in a Laboratory Rocket Engine.
(2009)
Coaxial jets are commonly used as injectors in propulsion and combustion devices due to both the simplicity of their geometry and the rapid mixing they provide. In liquid rocket engines it is common to use coaxial jets in ...
High Intensity Organic Light-Emitting Diodes.
(2012)
This thesis is dedicated to the fabrication, modeling, and characterization to achieve high efficiency organic light-emitting diodes (OLEDs) for illumination applications. Compared to conventional lighting sources, OLEDs ...
Optical Response and Control of Molecular Systems.
(2010)
This thesis is comprised of three major parts and is concerned with the theoretical characterization of condensed phase systems within the framework of nonlinear spectroscopy experiments, using both analytical models and ...
Making Small Holes With Lasers.
(2010)
The femtosecond laser is an advantageous tool for manipulating matter on small scales as it can precisely remove material with minimal collateral effects. The nonlinear mechanisms mediating this damage allow for laser ...
Regulating Gene Expression Through DNA Mechanics: Tightly Looped DNA Represses Transcription.
(2010)
It is now widely accepted that the mechanical state of DNA can play a major role in regulating the activity of RNA polymerase (RNAP). Not only have the global levels of supercoiling been shown to regulate transcription, ...
Sum Frequency Generation Vibrational Spectroscopy Investigation of Buried Polymer and Organic Interfaces.
(2009)
It is difficult to elucidate buried interfaces because of the lack of appropriate analytical techniques. In this thesis, it was shown that sum frequency generation vibrational spectroscopy (SFG) can be used to probe ...
Fast Neutron Measurements using Deuterated Liquid Scintillators.
(2009)
This dissertation in experimental nuclear physics describes the construction, design, assembly and tests of a novel 2" X 2" deuterated liquid scintillator, and a series of nuclear reaction experiments using the detector ...
