Experimental Realization of Improved Magnetic Sensing and Imaging in Ensembles of Nitrogen Vacancy Centers in Diamond
(2020-09-10)Nitrogen-vacancy color centers in diamond constitute a leading quantum sensing platform, with particularly diverse applications in magnetometry. The negatively-charged NV center (NV) exhibits a long-lived electronic ... -
Experimental Studies of Human Behavior in Social Computing Systems
(2015-05-18)Social computing systems, fueled by the ability of the Internet to engage millions of individuals, have redefined computation to include not only the application of algorithms but also the participation of people. Yet, the ... -
Experiments and Analysis of Mitochondrial DNA Segregation, Yeast Polarization and RNA Polymerase Dynamics
(2015-03-27)This thesis presents work done in three different topics in biology with a combination of experiments, mathematical modeling and quantitative data analysis. All cellular materials are partitioned between daughters at cell ... -
Experiments on Universal Rigidity of Bipartite Graphs
(2015-04-08)Our goal is to characterize necessary and sufficient conditions for the universal rigidity of bipartite frameworks. Previous work describe ways to test universal rigidity through semidefinite program- ming using stress ... -
Expertise Diversification and the Transformation of the Field of Contemporary Chinese Art: 1979-2012
(2013-10-18)The decentralization of cultural production in China coincided with the introduction of economic and political reforms in 1979. The subsequent shift from a system of state propaganda production towards a market-oriented ... -
Experts of the World Economy: European Stabilization and the Reshaping of International Order, 1916-51
(2016-09-14)This dissertation traces the origins of the earliest international schemes to manage the world economy between the middle of the First World War and the conclusion of the Second. It follows the emergence of a transnational ... -
Explaining by Conversing: The Argument for Conversational XAI Systems
(2021-06-23)The interest in chatbots and conversational agents is as old as artificial intelligence (AI) itself. Recently, multiple members of the HCI community including Weld and Bansal (2018) have suggested that conversational ... -
Exploiting signaling signatures in triple-negative breast cancer to identify targetable vulnerabilities
(2023-05-02)Triple-negative breast cancer (TNBC) is an aggressive and heterogeneous disease with the worst five-year survival rate of all breast cancer subtypes. The standard of care for TNBC is chemotherapy, but not all patients ... -
Exploiting the Regulation of Apoptosis to Improve Therapeutic Responses of Tumors to mTOR Inhibitors
(2023-01-09)The mechanistic target of rapamycin (mTOR) complex 1 (mTORC1) is constitutively activated in most human cancers and in the genetic tumor syndrome tuberous sclerosis complex (TSC). Due to its role in driving anabolic processes ... -
An Exploration of the Function of Lamps in Archaic and Classical Greek Culture: Use, Concepts, and Symbolism
(2013-02-13)Scholarship on Archaic and Classical Greek lamps has traditionally been in the form of typological studies and catalogues. This dissertation represents an alternative to such works, offering a fuller picture of the function ... -
Explorations in cancer genomics and tumor immunology through analysis of next-generation sequencing data
(2022-03-17)Cancer is an evolutionary disease. From the time we are a fertilized egg, our cells are subject to processes that can alter DNA sequence and epigenetics leading to random changes in cell fitness. Certain phenotypes can ... -
Explorations in de Sitter Space and Amorphous Black Hole Bound States in String Theory
(2013-09-30)This dissertation is split into two distinct halves. The first covers various calculations done in order gain insights on holography in de Sitter space. The dispersion relation of linear perturbations of empty de Sitter ... -
Exploring Biomolecular Interactions Through Single-Molecule Force Spectroscopy and Computational Simulation
(2016-04-11)Molecular interactions between cellular components such as proteins and nucleic acids govern the fundamental processes of living systems. Technological advancements in the past decade have allowed the characterization of ... -
