Diet, Metabolomics, and Colorectal Cancer Risk
(2021-07-12)Colorectal cancer (CRC) is the third most common cancer and the second leading cause of cancer death in 2020 globally. In the United States, although the estimated 2021 CRC incidence only ranks fourth among all cancers, ... -
Dietary Patterns and Major Chronic Diseases
(2022-11-23)Dietary improvement may lower the risk of developing chronic diseases and associated mortality. Despite the existence of several disease-oriented dietary recommendations, the superior diets for general health and specific ... -
Dietary Restriction-Induced Longevity in Caenorhabditis elegans: Mediated by Stress Defense, NAD\(^+\)-Dependent Mechanisms and a Respiratory Shift
(2014-06-06)Dietary restriction (DR), or the reduction of food consumption without malnutrition, is the most conserved method of preventing or reversing age associated diseases. It is also the most conserved method of increasing ... -
Dietary supplements, dietary patterns, and prostate cancer prevention
(2023-06-01)Dietary supplements are widely used among men in the US. The effect of vitamin and mineral supplements on the risk of non-communicable diseases in ‘generally healthy’ populations is controversial. Current guidelines conclude ... -
Differential fluorescence-based genetic screens to identify novel Listeria monocytogenes virulence determinants
(2015-01-23)Listeria monocytogenes is a Gram-positive, facultative intracellular pathogen that causes gastroenteritis, which in the young, the elderly, and the immunocompromised can progress to severe invasive disease with high ... -
Differential Innate Immune Stimulation Elicited by Adenovirus and Poxvirus Vaccine Vectors
(2014-02-25)Vaccines are one of the most effective advances in medical science and continue to be developed for applications against infectious diseases, cancers, and autoimmunity. A common strategy for vaccine construction is the use ... -
The Differential Privacy of Bayesian Inference
(2015-04-08)Differential privacy is one recent framework for analyzing and quantifying the amount of privacy lost when data is released. Meanwhile, multiple imputation is an existing Bayesian-inference based technique from statistics ... -
Differentially Private Ridge Regression: The Cost of a Hyperparameter
(2021-06-04)Studying problems of interest, like finding trends in medical data, can require analyzing data which contains sensitive and personally identifying information. As a result, it is often infeasible to release these datasets ... -
Differentiated Products, Divided Industries: Firms and the Politics of Intra-Industry Trade
(2013-09-18)Which firms support trade liberalization and under what circumstances? The dominant approaches to trade politics ignore two key features of modern international commerce -- firm heterogeneity in export performance and ... -
Differentiating Human and Machine Intelligence with Contextualized Embeddings
(2023-06-30)This thesis explores the application of deep learning models as contextual embedding functions for data enrichment in the Turing test, allowing an AI-based judge that automates the Turing test to more effectively differentiate ... -
Diffusion, Absorbing States, and Nonequilibrium Phase Transitions in Range Expansions and Evolution
(2014-10-21)The spatial organization of a population plays a key role in its evolutionary dynamics and growth. In this thesis, we study the dynamics of range expansions, in which populations expand into new territory. Focussing on ... -
Diffusion, Deformation, and Damage in Lithium-Ion Batteries and Microelectronics
(2014-06-06)This thesis explores mechanical behavior of microelectronic devices and lithium-ion batteries. We first examine electromigration-induced void formation in solder bumps by constructing a theory that couples electromigration ... -
Diffusive waves, dynamic instability, and chromosome missegregation: dimensionality, discreteness, stochasticity
(2022-05-06)Modeling biological systems is challenging because many processes act at the same scale, and because biological systems span many scales. Because it is difficult or impos- sible to know everything about a given cell, tissue, ... -
Digesting Modernism: Representations of Food and Incorporation in Nineteenth and Twentieth-Century French Fiction
(2013-10-18)This dissertation examines the link between food and writing about food in French modernist texts in nineteenth and twentieth-century French novels, tracing the central role of food in realist fiction as an encoder of ... -
Digital Jianghu: Independent Documentary in a Beijing Art Village
(2013-09-19)My ethnography explores the independent documentary film community in Songzhuang, an artist village in Beijing's Tongzhou District. Through participant-observation, interviews, participation in festivals, and my own ... -
Dilemmas in Design: From Neyman and Fisher to 3D Printing
(2014-06-06)This manuscript addresses three dilemmas in experimental design. -
Dilemmas of Delegation: The Politics of Authority in International Courts
(2016-05-16)One of the most enduring questions for the study of politics relates to what, if any, inde- pendent power international institutions have to affect the behavior of sovereign states. This dissertation addresses this question ... -
Dimensionality Reduction of Dynamic Topic Models Using a Finite State Machine Representation
(2017-07-14)Dynamic topic models produce semantically interpretable topics that describe data evolving through time. The number of these topics increases with the range of time fitted, diminishing the interpretability of the model ... -
Dimensions of Disadvantage: Normative and Empirical Analysis of the Effect of Public Insurance on Low-Income Children and Families
(2012-07-27)This dissertation considers some challenges to delivering effective and equitable health care to disadvantaged children and families in the United States. Chapter one examines whether expanded access to health insurance ... -
Dinosaurs: Assembling an Icon of Science
(2013-03-08)This dissertation examines how the modern dinosaur—fully mounted, freestanding assemblages of vertebrate fossils such as we are accustomed to seeing at the natural history museum—came into being during the late 19th and ...
