Advances in Ab Initio Modeling of the Many-Body Effects of Dispersion Interactions in Functional Organic Materials
(2015-12-04)Accurate treatment of the long-range electron correlation energy, including dispersion interactions, is essential for describing the structure, dynamics, and function of a wide variety of systems. Among the most accurate ... -
Advances in Crystal Growth and Assembly for Imparting Novel Photonic Properties to Semiconductor Nanowires
(2015-08-17)Semiconductor nanowires comprise a versatile materials platform with which to characterize the properties of nanomaterials. The vast range of structural and compositional diversity of nanowires has also enabled their use ... -
Advances in Empirical Bayes Modeling and Bayesian Computation
(2013-08-14)Chapter 1 of this thesis focuses on accelerating perfect sampling algorithms for a Bayesian hierarchical model. A discrete data augmentation scheme together with two different parameterizations yields two Gibbs samplers ... -
Advances in Monte Carlo Variational Inference and Applied Probabilistic Modeling
(2018-05-10)Galvanized by the accelerated pace and ease of data collection, researchers in more and more disciplines are turning to large, heterogeneous datasets to answer scientific questions. Divining insight from massive and complex ... -
Advances in Phage-Assisted Continuous Evolution and Application to Overcoming Bioinsecticide Resistance
(2016-05-20)The Bacillus thuringiensis δ-endotoxins (Bt toxins) are widely used insecticidal proteins in engineered crops that provide agricultural, economic, and environmental benefits, constituting a substantial and increasingly ... -
Advances in Statistical Network Modeling and Nonlinear Time Series Modeling
(2018-05-11)The thesis is composed of two independent topics: statistical network modeling and nonlinear time series modeling. With the increasing demand of network data analysis, we present two statistical network models and inferences, ... -
Advances in the Measurement of the Electron Electric Dipole Moment
(2023-05-10)Searches for the electron electric dipole moment (eEDM) are powerful tests of physics beyond the standard model, as they probe for new evidence of time-reversal violating interactions. In 2018 our ACME collaboration reported ... -
Advances in the Normal-Normal Hierarchical Model
(2014-06-06)This thesis consists of results relating to the theoretical and computational advances in modeling the Normal-Normal hierarchical model. -
Advancing and Applying Precision Genome Editing Technologies
(2021-03-30)Since the discovery of the chemical structure of DNA, researchers have endeavored to understand how the chemical properties of this complex molecule provide a blueprint for biological function. The ability to modulate ... -
Advancing precision genome and transcriptome engineering
(2022-11-23)The cells within all living organisms contain genomic DNA that encodes the information for their structure, function, and capabilities. According to the central dogma of biology, this DNA is transcribed to RNA and this RNA ... -
Advancing the capabilities of base editing and protein delivery
(2023-11-21)Genome editing technologies can in principle enable powerful new therapeutic strategies, including possible cures for deadly genetic disorders. Realizing the therapeutic potential of genome editing requires the ability to ... -
Advection on Graphs
(2017-02-07)We give an overview of advection on graphs and relate it to Markov chains and covering graphs. -
Adverse Birth Outcomes in Botswana: Findings from the Tsepamo Study
(2023-08-08)The Botswana-Harvard AIDS Institute Partnership (BHP) was formed in 1996 between the Government of Botswana’s Ministry of Health and the Harvard T.H. Chan School of Public Health. Research conducted under this partnership ... -
Adverse Experiences, Psychopathology, and Brain Morphology in Longitudinal Cohort Studies
(2023-06-01)Exposure to adverse experiences in childhood, including trauma and poverty, is linked to increased risk for psychopathology, such as depression and posttraumatic stress disorder (PTSD) in adolescence and adulthood. While ... -
Advocacy and Anti-Racism: How Institutions Shape Organizational Responses to Racially Biased Policing in France and the United States
(2017-05-13)Racially biased policing has captured the attention of citizens across the globe. This preoccupation with racial justice and policing is not unique the United States; these questions are on the rise across the Atlantic as ... -
The Aesthetics of Discovery: Text, Image, and the Performance of Knowledge in the Early-Modern Book
(2015-05-21)How does the book-object in early modernity participate in the representation of scientific knowledge? How was the reader meant to approach the book and to comprehend its contents? This project starts from the contention ... -
Affecting Lives: The Politics of Biography in Modern Italy, 1850-1881
