Two Applications of Summary Statistics: Integrating Information Across Genes and Confidence Intervals With Missing Data
(2018)Gene set enrichment methods are useful for the mapping of individual genes or proteins to pathways and signatures. We use this approach to study the expression levels of proteins encoded by different genes, andd ... -
Biotic Interactions in the Genus Anthurium Schott (Araceae)
(2018)The genus Anthurium represents one of the largest genera restricted to the neotropics and has long been recognized as one of the "megagenera" of flowering plants, in addition to claiming the bulk of diversity (~25%) in iits ... -
Improving Stability and Selectivity in Electrochemical Reduction of Carbon Dioxide in an Aqueous Solution
(2018)With the rising level of CO2 in the atmosphere, methods capable of converting CO2 into useful fuels are urgently needed. The electrochemical CO2 reduction has gained significant interest recently due to its ability to usse ... -
Aerodynamic Optimization of Helicopter Rotors using a Harmonic Balance Lifting Surface Technique
(2018)This thesis concerns the optimization of the aerodynamic performance of conventional helicopter rotors, given a set of design variables to control the rotor's pitching angle, twist and chord distributions. Two models aree ... -
Secure Control of Cyber-Physical Systems with Intermittent Data Authentication
(2018)The increase in network connectivity has also resulted in several high-profile attacks on cyber-physical systems. An attacker that manages to access a local network could remotely affect control performance by tampering ... -
Predictors of Death Among HIV-Infected Adults Receiving Antiretroviral Therapy in Tanzania
(2018)Introduction: Mortality among HIV-infected individuals in sub-Saharan Africa, the region most affected by the HIV epidemic, has declined remarkably since the rapid scale-up of antiretroviral therapy (ART). Despite encourraging ... -
Hospital-based quality improvement interventions for patients with heart failure: A systematic review
(2018)Importance: Quality improvement initiatives have been developed to improve clinicaloutcomes in patients with heart failure (HF), but data from randomized trials of theseinitiatives have not previously been synthesized.Obbjective: ... -
Multiphase Flow in a Hele-Shaw Cell
(2018)The primary goal of this thesis is to explore the capabilities of MOOSE (MultiphysicsObject Oriented Simulation Environment) and LAMMPS (Large-scale Atomic/MolecularMassively Parallel Simulator) and their potential to bee ... -
Applied Dynamic Factor Analysis for Macroeconomic Forecasting
(2018)The use of dynamic factor analysis in statistical modeling has broad utility across an array of applications. This paper presents a novel hierachical structure suited to a particular class of predictive problems - those ... -
Algorithms for Allocation Problems in Online Settings
(2018)A fundamental computational challenge that arises in the operation of online systems, services, and platforms is that of resource allocation. Broadly defined, a resource allocation problem is one where set of users generaate ... -
Advances in Bayesian Modeling of Protein Structure Evolution
(2018)This thesis contributes to a statistical modeling framework for protein sequence and structure evolution. An existing Bayesian model for protein structure evolution is extended in two unique ways. Each of these model exttensions ... -
Metal-Ligand Interactions in Stimuli Responsive Molecules
(2018)The ability to control changes in physical and chemical properties has allowed stimuli responsive molecules to be used in a variety of applications. Incorporating metals into stimuli responsive molecules introduces propeerties ... -
Essays on Propensity Score Methods for Causal Inference in Observational Studies
(2018)In this dissertation, I present three essays from three different research projects and they involve different usages of propensity scores in drawing causal inferences in observational studies. Chapter 1 talks about the ... -
"Into the Mainstream and Oblivion": Julian Mayfield's Black Radical Tradition, 1948-1984
(2018)“Into the Mainstream and Oblivion” is a study of the intellectual and political biography of the African American writer and political activist Julian Hudson Mayfield. As a member of the black Left, Mayfield’s life of acctivism ... -
Development of Multimodal Optical System Guided by Optical Coherence Tomography
(2018)The goal of this dissertation is to develop multimodal light scattering techniques using optical coherence tomography (OCT) to improve clinical diagnosis. OCT is a non-invasive optical imaging technique that utilizes loww ... -
3D Printable Lithium Ion Batteries and the Effect of Aspect Ratio of CuAg Nanowires on Graphite Anode Performance.
(2018)The majority of consumer electronic devices, electric vehicles, and aerospace electronics are powered by lithium ion batteries because of their high energy and power densities. Commercially available lithium ion batteriees ... -

(2018)This dissertation consists of three theoretical essays on delegation and mechanism design.Chapter 2 is co-authored with Attila Ambrus and Aaron Kolb. We investigate competition in a delegation framework. An uninformedpriincipal ... -
Genetically Encoded Albumin Binding Drug Delivery Systems
(2018)Albumin is emerging as a promising and versatile carrier to improve the pharmacokinetic and therapeutic profiles of drugs because of its unique physiological properties. The objective of this dissertation is to develop ddrug ... -
Finite Sample Bounds and Path Selection for Sequential Monte Carlo
(2018)Sequential Monte Carlo (SMC) samplers have received attention as an alternative to Markov chain Monte Carlo for Bayesian inference problems due to their strong empirical performance on difficult multimodal problems, natuural ... -
Fluid Flow and Electromagnetic Fields Modeling for Geophysical Subsurface Sensing
(2018)Crosswell electromagnetic (EM) fields measurement has been widely applied in oil industry which has a reservoir scale detection range. One of the limitation of this technique is that the EM singals are usually too weak tto ...
