Intrinsically Disordered Protein Polymer Libraries as Tools to Understand Protein Hydrophobicity
(2019)Intrinsically disordered protein polymers (IDPPs) are repetitive biopolymers that, when enriched with prolines, glycines, and aliphatic amino acids, have observable lower critical solution temperature (LCST) phase transition ... -
The Potential Role of Memory in the Development and Maintenance of Binge and Loss of Control Eating
(2019)Binge and loss of control (LOC) eating are clinically significant symptoms that constitute syndromes characterized by a repetitive pattern of maladaptive and subjectively uncontrollable binge or loss of control eating. The ... -
Linear Dimension Reduction Approximately Preserving Level-Sets of the 1-Norm
(2019)We choose a family of matrices F : \R^D \to \R^k and a metric \rho on \R^k such that with highprobability, \rho(F (x), F (y)) is a strictly concave increasing function of ||x − y||_1 > 8 \epsilon^2for x, y \in \R^D , up ... -
Definition of a murine CD8+ MHCII-recognizing effector T cell population
(2019)CD4+ and CD8+ T cells are dichotomous lineages in adaptive immunity. While conventionally viewed as distinct fates that are fixed post-thymic development, accumulating evidence indicates that these two populations can exhibit ... -
Enabling Technologies for High-Rate, Free-Space Quantum Communication
(2019)Quantum communication protocols, such as quantum key distribution (QKD), are practically important in the dawning of a new quantum information age where quantum computers can perform efficient prime factorization to render ... -
Repeated Evolution of Asexuality Among Hybrids of A Recently Diverged Subspecies Pair in Boechera
(2019)The impacts of hybridization on speciation and biodiversity can be influenced by the persistence and the reproductive mode of hybrids. Persistent sexual hybrids can facilitate gene flow between parent taxa, which can potentially ... -
ESSAYS ON GLOBAL VALUE CHAINS, POLICIES AND INEQUALITY.
(2019)This thesis tackles development policy issues that arise when institutions have unequal power. It contributes to three fields: International Political Economy; Industrial Organization; Global Value Chain Analysis. Within ... -
Reading and Writing As/if: US Literary Criticism and Identity
(2019)As/if: US Literary Criticism and Identity turns to early queer and third-wave feminist scholarship to identify a unique strategy and style of literary criticism, which I name as/if criticism. As/if criticism is both born ... -
Holographic Methods for Light Manipulation at Microwave and Terahertz Frequencies
(2019)This dissertation is focused on the application of various holographic techniques to manipulate light across frequencies from low gigahertz to the terahertz. None of the holograms described rely on traditional holographic ... -
Riemannian 3-Manifolds with a Flatness Condition
(2019)The fundamental point-wise invariant of a Riemannian manifold $(M, g)$ is the Riemann curvature tensor. Many special types of Riemannian manifolds can be characterized by conditions on the Riemann curvature tensor and tensor ... -
Essays in Political Economy and Development Economics
(2019)This dissertation explores questions in political economy and in developmenteconomics. I ask and answer two research questions.First, I look at whether peaceful or violent protests are more effective atsteering policy change. ... -
Graphic Intimations: Postwar to Contemporary Asian Diasporic Art and Writing
(2019)Graphic Intimations: Postwar to Contemporary Asian Diasporic Art and Writing follows the oblique tensions in Asian diasporic creative compositions between art and writing, performance and inscription. Identifying ... -
Authenticity and Enhancement
(2019)Recent accounts of authenticity have defined the concept in terms of self-creation, self-discovery, or some combination of the two. While these accounts get something right about the concept, I argue that they fail to capture ... -
Investigating the Geological and Biogeographical Cenozoic History of the Amazon-Andes Region
(2019)The Amazon-Andes region of tropical South America plays host to the world’s largest river, its highest biodiversity and one of its highest mountain chains, as well as a long and complex history. As such, it represents an ... -
Probing the Interfaces of Epigenetic Complexes: Efforts Towards Elucidating and Targeting Critical Protein:Protein and Protein:lncRNA Interactions of Lysine-Specific Demethylase 1 (KDM1A/LSD1)
(2019)The post translational modification (PTM) of histone proteins is a highly dynamic process that is utilized in the control of gene transcription. This epigenetic process involves enzymatic ‘writers’ and ‘erasers’ which place ... -
The Water-Energy Nexus for Hydraulic Fracturing
(2019)The water energy nexus represents the intersection of water use, energy production, electricity generation, and waste generation and disposal. The rapid rise of unconventional natural gas and oil production through the combined ... -
Analytical Models for the Structural-Acoustic Response of Elastic Barriers Subject to Acoustic Forcing
(2019)Analytical models are developed for the structural-acoustic response of flexible panels to obliquely incident, planar harmonic acoustic waves. These models provide a detailed understanding of the complex effects of structural ... -
Essays in Decision Theory
(2019)This dissertation consists of three essays in decision theory. The first chapter is an introduction. The second chapter studies individual decision making when deadlines are random. Since the quality of any decision relies ... -
Coordinating Software and Hardware for Performance Under Power Constraints
(2019)For more than 50 years since its birth in 1965, Moore's Law has been a self-fulfilling prophecy that drives computing forward. However, as Dennard scaling ends, chip power density presents a challenge that becomes increasingly ... -
Evolution, Development, and Morphology of Cetacean Skull Novelties
(2019)Novelty presents a paradox in evolutionary biology. Novel features appear to be qualitatively unique to a specific type of organism, but historical continuity requires that some common form must have pre-existed them. This ...
