1,2-Selective Hydrosilylation of Conjugated Dienes
(2014-06-06)Selective 1,2-hydrosilylation of 1,3-dienes is a challenging problem to solve for transition metal catalysis. Butadiene, specifically, would be a useful substrate because 3-butenylsilane products have promise as superior ... -
The 1824 Confederation of the Equator and Cultural Production in Brazil
(2015-05-17)During the 1824 Confederation of the Equator revolt in northeastern Brazil, a middle-class junta rose to power and waged a war against the monarchy in Rio, journalists participating in creating pedagogical ideological ... -
2-Selmer groups and Heegner points on elliptic curves
(2015-05-07)This thesis studies several aspects of the arithmetic of elliptic curves. In particular, we explore the prediction of the Birch and Swinnerton-Dyer conjecture when the 2-Selmer group has rank one. For certain elliptic ... -
21st Century Bricoleurs: Remaking Rural Japan
(2021-07-15)Isumi lacks the trappings that are often associated with ‘a city’. No high-rises adorn its skyline, no central business district hums 24/7 with energy generated by foot traffic and commerce, and no cultural hub serves as ... -
3D Bioprinting of Vascularized Human Tissues
(2016-04-26)The ability to manufacture human tissues that replicate the spatial, mechano-chemical, and temporal aspects of biological tissues would enable myriad applications, including drug screening, disease modeling, and tissue ... -
3D Printing of Liquid Crystal Elastomer Actuators
(2021-07-12)Soft robotics offer advantages over their rigid counterparts due to the intrinsic softness of their consisting materials, soft robotic matter. When equipped with programmable shape morphing and controllable function, soft ... -
4d Spectra from BPS Quiver Dualities
(2013-09-26)We attack the question of BPS occupancy in a wide class of 4d N = 2 quantum field theories. We first review the Seiberg-Witten approach to finding the low energy Wilsonian effective action actions of such theories. In ... -
A Bayesian Nonparametric Approach to Multi-Task Learning for Contextual Bandits in Mobile Health
(2022-06-03)Reinforcement learning algorithms have found utility in a number of digital interventions, such as in mobile health (mHealth), wherein N users are followed and sequentially treated over T timesteps with the aim of optimizing ... -
A Calibrated Defocus Simulator for Research in Passive Ranging
(2022-05-23)Depth from defocus is a prominent area of computer vision research, yet unlike many other areas of the field, there is no dedicated dataset or general library for training and testing depth from defocus applications. As a ... -
A Capitalizing City: Dar Es Salaam and the Emergence of an African Entrepreneurial Elite (C. 1862-2015)
(2018-09-19)A Capitalizing City charts the ways some people of African descent in Dar es Salaam, the commercial and industrial capital of Tanzania, have attempted, historically, to either integrate into the modern capitalist system ... -
A Clock-Phased Sigma Factor Cascade Is Required for Global Circadian Transcriptional Rhythms in Cyanobacteria
(2017-09-07)The circadian clock of the cyanobacterium Synechococcus elongatus PCC 7942 drives oscillations in global mRNA transcript abundances with 24 h periodicity under continuous light conditions. The transcription factor RpaA ... -
A Combinatorial Maf Transcription Factor Code Establishes Synaptic Heterogeneity Critical for Normal Hearing Function
(2023-01-18)Spiral ganglion neuron (SGN) synaptic, functional, and molecular diversity is critical for hearing function. Heterogeneous inner hair cell (IHC)-SGN synapses transduce complex sound information from the ear to the brain. ... -
A Computational Approach for Detailed Quantification of Mouse Parenting Behavior
(2022-05-23)A major aim of neuroscience is understanding the brain circuitry underlying observable behaviors. Recently, an increasing number of tools have allowed researchers to investigate brain circuitry in unprecedented ways. ... -
A Computational Approach to Analysis and Control\\of the Mammalian Circadian Oscillator
(2018-05-11)Circadian rhythms, endogenous, entrainable, near-24 h oscillations in metabolism, are a nearly ubiquitous feature of life on Earth. Circadian rhythms function as a feedforward biological control system that reorganizes ... -
A Declarative Specification for Machine Learning Architectures
(2023-06-30)Going from the description of a model architecture in a figure to its implementation can be a fraught process. This work presents a markup language for specifying model architectures; an associated Python package used to ... -
A Deluge of Tears: The Conflux of Persian Shiʿi Literature, Ritual, and Identity in Martyrdom Narratives
(2021-05-13)This dissertation presents the first English in-depth study of one of the most important maqtals (martyrdom narratives) ever written in Persian, the Rowz̤at ol-Shohadā’ (Meadow of the Martyrs) by Ḥoseyn b. ʿAlī Beyhaqī ... -
