Dimensionality reduction for k-means clustering
(Massachusetts Institute of Technology, 2015)In this thesis we study dimensionality reduction techniques for approximate k-means clustering. Given a large dataset, we consider how to quickly compress to a smaller dataset (a sketch), such that solving the k-means ... -
Dimensionality reduction for sparse and structured matrices
(Massachusetts Institute of Technology, 2015)Dimensionality reduction has become a critical tool for quickly solving massive matrix problems. Especially in modern data analysis and machine learning applications, an overabundance of data features or examples can make ... -
Dimensionality reduction in immunology : from viruses to cells
(Massachusetts Institute of Technology, 2015)Developing successful prophylactic and therapeutic strategies against infections of RNA viruses like HIV requires a combined understanding of the evolutionary constraints of the virus, as well as of the immunologic ... -
Dimensions of ergativity in Inuit : theory and microvariation
(Massachusetts Institute of Technology, 2018)This thesis investigates microvariation in the ergative system of the Inuit dialect continuum, as a window into the theoretical status of ergative alignment, argument licensing, and Agree. The empirical focus of this thesis ... -

Dimensions of microbial biodiversity in the North Pacific subtropical Gyre
(Massachusetts Institute of Technology, 2017)Microorganisms support all life in the oceans and are fundamental to maintaining a habitable biosphere on Earth. However an understanding of their taxonomic and functional distributions across space and time are just ... -
Dimensions of symmetry in syntax : agreement and clausal architecture
(Massachusetts Institute of Technology, 2005)(cont.) are, then, determined at phase levels by late insertion of categorial features. One crucial aspect of the proposed theory of structural symmetry involves interweaving effects, which emerge as categorial determination ... -

Diné Bizaad Bitsisiléí Bóhoo’aah: A Basis for learning Navajo
(Massachusetts Institute of Technology, 2022-05)This guide is meant to provide a brief introduction to the Navajo language, Diné Bizaad. It is understood that most of the present Diné youth speak English as their only language, as the population of Diné Bizaad speakers ... -
Dinitrogen and organometallic chemistry of trimethylsilyl-substituted triamidoamine complexes of molybdenum
(Massachusetts Institute of Technology, 1999){ [N 3N]Mo-N=N} 2Mg(THF)2, isolated from the reduction of [N3N]MoCl by magnesium powder under dinitrogen, serves as an entry into the dinitrogen chemistry of molybdenum complexes containing the TMS-TREN ligand. ... Five ... -
Dinitrogen fixation chemistry of a molybdenum trisanilide system
(Massachusetts Institute of Technology, 2009)Dinitrogen cleavage by Mo(N[t-Bu]Ar)3 (Ar = 3,5-C6H3Me2) proceeds through the intermediate ([mu]-N2)[Mo(N[t-Bu]Ar)3]2 before forming N=Mo(N[t-Bu]Ar)3 as the product. Both the intermediate bridging N2 complex and the nitride ... -
The dinner party
(Massachusetts Institute of Technology, 2009)This manuscript both describes and documents the artistic practice that I have developed during my time at MIT in the Visual Arts Program. This writing presents three projects created during my time as a graduate student ... -
Dioxygen activation and substrate hydroxylation by the hydroxylase component of toluene/O-xylene monooxygenase from pseudomonas sporium OX1
(Massachusetts Institute of Technology, 2007)Non-heme carboxylate-bridged diiron centers in the hydroxylase components of the bacterial multicomponent monooxygenases activate dioxygen at structurally homologous active sites. Catalysis requires the management of four ... -
Diplomacy derailed : the consequences of U.S. diplomatic disengagement
(Massachusetts Institute of Technology, 2011)Advocates of diplomatic engagement with states of concern argue that talking to both allies and adversaries is essential for advancing U.S. foreign policy interests. Critics of this approach argue that engagement with these ... -
Diplomatic : letter from the architectural enclave
(Massachusetts Institute of Technology, 2015)Seeing Architecture as a political art, this thesis concerns itself with boundaries: those of regimes, of culture, of law, and of social strata. In a silent crisis where sustained inscription of physical and social boundaries ... -

Dipolar Shielding and Sub-wavelength Bilayers in a Quantum Gas of Dysprosium
(Massachusetts Institute of Technology, 2023-02)In our paper Can the Dipolar Interaction Suppress Dipolar Relaxation?, by using magnetic dysprosium atoms and an optical lattice we engineered the dipolar suppression of dipolar relaxation in an ultra-cold gas prepared in ... -

A diquark interpretation of the structure and energies of hadrons
(Massachusetts Institute of Technology, 2005)I present a simple phenomenological model which successfully organizes and classifies essentially all hadrons. The model is originally inspired from three simple theoretical indications including: treating baryons as a two ... -
Dirac operators and monopoles with singularities
(Massachusetts Institute of Technology, 2007)This thesis consists of two parts. In the first part of the thesis, we prove an index theorem for Dirac operators of conic singularities with codimension 2. One immediate corollary is the generalized Rohklin congruence ...
