U.S. Federal Water Pollution Control: How History Has Contributed to the Mismatch Between the Legal Framework and the Current State of the Science
(2015-04-24)The current framework under which federal authorities regulate waters of the United States is in many ways constrained by our history. Regulatory policy and scientific understanding have developed on parallel but independent ... -
U.S. Fiscal Multipliers
(2015)This paper investigates whether government spending multipliers are time-varying.The multipliers are measured using time-varying parameter (TVP) local projections.This paper uses a simple modication to local projections ... -
U.S. Policy in Moldova: Balancing the Threat of Russian Influence and U.S. Interests
(2015-05-01)In recent months, disputes between Russia and its neighbors have accelerated to levels nearing those seen during the Cold War. The effects of globalization and Western economic integration have initiated democratic development ... -
U.S.-China Solar Trade War: Economic and Political Implications of the 2012 and 2014 Antidumping Disputes
(2014-12-08)Following the 2011 flood of Chinese solar photovoltaic (PV) panels, SolarWorld and a conglomerate of six unnamed U.S. solar cell and module manufacturers filed a lawsuit in October 2011 against Chinese producers alleging ... -
U.S.-Turkish Relations: Re-situating the “Kurdish Question”
(2016-04-19)Historically many American policymakers have not prioritized the status of Turkey’s Kurds in bilateral relations, despite the significant political, cultural, and security implications of the “Kurdish Question”. The events ... -
U.S./China Trade Disputes in the post-Recession Political Landscape
(2013-12-30)This paper investigates the connection between the recent economic recession and an increase in trade disputes between the United States and China. Overall, I conclude political factors exacerbated by the recession, rather ... -
Ubiquitin Recognition by Ubiquitin-Binding Domains in Y-Family DNA Polymerases
(2009)Translesion synthesis (TLS) is a specialized type of DNA repair for bypassing DNA damage at the stalled replication fork. Because the TLS polymerases (mainly from the Y-family of polymerases) are characterized by more open ... -
The `Ulama' and the State: Negotiating Tradition, Authority and Sovereignty in Contemporary Pakistan
(2014)This dissertation is an account of how contemporary Pakistani ulama grapple with their political realities and the Islamic state of Pakistan. The central conceptual question that scaffolds my dissertation is: How do Pakistani ... -
Ultimate Causes and Consequences of Coloration in North American Black Widows
(2015)Researchers have long assumed that black widow coloration functions as a warning signal to avian predators. However adult female black widow coloration does not resemble typical warning coloration in two distinct ways. ... -
Ultra High Pressure Hydrogen Studies
(2016)Hydrogen has been called the fuel of the future, and as it’s non- renewable counterparts become scarce the economic viability of hydrogen gains traction. The potential of hydrogen is marked by its high mass specific energy ... -
Ultracold Fermi Gases in a Bichromatic Optical Superlattice
(2016)I describe the theory and construction of a new bichromatic optical superlattice to study the pairing and thermodynamics of spin $\frac{1}{2}$-up and spin $\frac{1}{2}$-down atoms in periodic double well potentials. Our ... -
Ultrafast Pump-Probe Microscopy in Cultural Heritage Research
(2015)The materials and working method of a painting can reveal important information about our cultural history, as well as lend the conservator the necessary knowledge for treatment options. The removal of a cross-section ... -
Ultrasonic Investigation of Hepatic Mechanical Properties: Quantifying Tissue Stiffness and Deformation with Increasing Portal Venous Pressure
(2014)In this work, I investigate the mechanical response of the liver to increasing pressure in the portal vein using ultrasonic approaches. In advancing liver disease, portal venous pressure increases lead to severe clinical ... -
Ultrasound Beamforming Methods for Large Coherent Apertures
(2017)This dissertation investigates the use of large coherent ultrasound apertures to improve diagnostic image quality for deep clinical targets. The current generation of ultrasound scanners restrict aperture size and geometry ... -
The Ultrasound Brain Helmet: Simultaneous Multi-transducer 3D Transcranial Ultrasound Imaging
(2012)In this work, I examine the problem of rapid imaging of stroke and present ultrasound-based approaches for addressing it. Specifically, this dissertation discusses aberration and attenuation due to the skull as sources ... -
Ultrasound Catheter Transducers for Intracranial Brain Imaging and Therapy
(2011)Each year, over 13,000 people in the United States die from a primary malignant brain tumor. Currently, primary BTs are treated most commonly by surgery, radiotherapy, and systemic chemotherapy, though each of these methods ... -
Umbilical Cord Blood Derived Endothelial Progenitor Cells: Isolation, Characterization, and Adhesion Potential in Vitro and in Vivo
(2009)The number one cause of death in the industrialized world, atherosclerosis, can be treated through a variety of methods: angioplasty, stenting, vein graft bypass, synthetic grafts, and maybe one day tissue engineering ... -
An Umpolung Approach to the α-Functionalization of Ketones and Aldehydes
(2011)The α-alkylation of N-sulfonyl hydrazones via in situ-derived azoalkenes provides an umpolung approach to ketone α-alkylation that has considerable potential with regard to catalysis and the direct incorporation ... -
The (Un)Folding of Multidomain Proteins Through the Lens of Single-molecule Force-spectroscopy and Computer Simulation
(2016)Proteins are specialized molecules that catalyze most of the reactions that can sustain life, and they become functional by folding into a specific 3D structure. Despite their importance, the question, "how do proteins ...
