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 ...
Topics in Networks: Community Detection, Random Graphs, and Network Epidemiology.
(2012)
In this dissertation, we present research on several topics in networks including community detection, random graphs, and network epidemiology.
Traditional stochastic blockmodels may produce inaccurate fits to complex ...
Two-Dimensional Electronic Spectroscopy of the Photosystem II D1D2-cyt.b559 Reaction Center Complex.
(2010)
Two-dimensional electronic spectroscopy (2DES) is a powerful new technique for examining the electronic and vibronic couplings and dynamics of chemical, semiconductor, and biological samples. We present several technical ...
Measurement of the Inclusive Forward-Backward tt Production Asymmetry and its Rapidity Dependence dAfb/d(y).
(2010)
Early measurements of a large forward-background asymmetry at the CDF and D0 experiments at Fermilab have generated much recent interest, but were hampered by large uncertainties. We present here a new measurement of the ...
New Models of Dark Matter and Prospects for Measurements.
(2011)
This thesis covers a range of topics in model building and measurements with an
interest in solving the dark matter problem.
We begin with a model where the dark matter properties today are different than
they were at the ...
Simple Processes in Complex Places.
(2010)
Identical stochastic processes in different topologies can exhibit qualitatively distinct behavior. In complex environments, such as social or neuronal networks, rich structural details can lead to very different outcomes ...
