    • 1,2-Selective Hydrosilylation of Conjugated Dienes 

      Parker, Sarah Elizabeth (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 

      Degoes, Plinio T. (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 

      Li, Chao (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 ...
    • 3D Bioprinting of Vascularized Human Tissues 

      Kolesky, David Barry (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 ...
    • 4d Spectra from BPS Quiver Dualities 

      Espahbodi, Sam (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 Discriminative Model to Predict Comorbidities in ASD 

      Hashmi, Amna (2016-06-21)
      Children with autism spectrum disorders face a higher comorbidity burden than the general pediatric population. Machine learning applications have been applied to structured medical data, specifically electronic health ...
    • A Floating Probe Force Microscope With Sub-Femtonewton Resolution 

      Liu, Lulu (2017-01-13)
      Forces at the femtonewton level and below are poised to be highly relevant in a number of scientific disciplines– including studies in optics and photonics, molecular biology, and even microfluidics. It is highly practical, ...
    • A Formalization of Elements of Special Relativity in Coq 

      Lu, Eric Hanqing (2017-07-14)
      We present a formalization of elements of special relativity in Coq beginning from a set of first-order axioms, towards demonstrating that Coq may be used to formalize physical reasoning at the level of introductory physics. ...
    • A Framework for Understanding Small Nervous Systems 

      Lee, Jeffrey B. (2017-01-09)
      How do we find important neurons and understand how their dynamics control behavior? Both of these are challenging and general problems in neuroscience. In this dissertation supervised by Sharad Ramanathan, I developed a ...
    • A Graphical Theory of Musical Pitch Spelling 

      Wetherfield, Benjamin S. (2018-06-29)
      Based on the conventions of staff-based music notation, musical passages that sound alike can often be written down in multiple ways, with each representation being considered a different "pitch-spelling". In this thesis, ...
    • A Living Extracorporeal Device for Proximal Tubule Reabsorption 

      Hink, Matthew Brent (2017-07-14)
      Currently, 700,000 patients suffer from end-stage renal disease (ESRD) with treatment costs over $42B in the US, yet the 5-year survival of patients on dialysis is only 35% while that of full-organ transplantation is over ...
    • A Markov Approach to Modeling Baseball At-Bats and Evaluating Pitcher Decision-Making and Performance 

      Casey, Nathaniel (2016-06-21)
      The author models baseball at-bats using absorbing Markov chains, formed based on pitch-by-pitch data for 90 pitchers from the 2015 season. These matrices are used to reverse-predict performance statistics that compare ...
    • A Neural Framework for Low-Shot Learning 

      Wang, Alex (2017-07-14)
      There has been a growing interest in developing machine learning models that are capable of low- shot learning, the machine learning problem of learning from little data. Progress on low-shot learning has important practical ...
    • A Nuclear Option for Climate Change: Historical lessons for the future of advanced fission energy in the United States 

      Pawar, Sohum (2018-06-29)
      As the largest source of emissions-free electricity in the United States, nuclear energy plays a pivotal role in efforts to combat climate change by decarbonizing our energy system. However, as the climate-energy challenge ...
    • A Portable Microfluidic Paper-Based Device for Performing ELISA 

      Chen, Austin (2016-06-30)
      Standard diagnostic tests for the detection of diseases typically cannot be performed in low-resource settings because they require equipment and conditions found in a laboratory. To address this problem, rapid test devices ...
    • A Portrait of Terrestrial Volatile Evolution From Mantle Noble Gases
