Expanding the Dimensions of a Small, Two-Dimensional Diffraction Detector
(Cambridge University Press (CUP), 2020-08)We report an approach to expand the effective number of pixels available to small, two-dimensional electron detectors. To do so, we acquire subsections of a diffraction pattern that are then accurately stitched together ... -
Expanding the first line of defense : AIDS, orphans and community-centered orphan-care institutions in Sub-Saharan Africa : cases from Zambia
(Massachusetts Institute of Technology, 2002)This thesis is about expanding the "first line of defense" for children and families affected by AIDS in sub-Saharan Africa. The overwhelming consensus among actors leading the fight against AIDS, ranging from USAID and ... -
Expanding the Freight Contract Portfolio: Index-Based Freight Contract Design Under Uncertainty
(2022-03-23)Long-term, fixed-price contracts in the truckload transportation sector have been the prevailing relationship form between firms and their for-hire transportation service providers. While advantageous for planning and ... -
Expanding the housing supply through conversions of the existing stock
(Massachusetts Institute of Technology, 1990)A large share of households remain poorly housed in the United States despite the steady improvement in overall housing conditions throughout the postwar period. Households that face the greatest difficulty in gaining ... -
Expanding the limits of Scale and sensitivity in microbial genomics
(Massachusetts Institute of Technology, 2018)Sequencing of microbial genomes has enabled new understanding of human health and disease. Certain microbes can support human health through the microbiota, helping to train our immune system or supply essential nutrients. ... -
Expanding the MicroRNA Targeting Code: Functional Sites with Centered Pairing
(Elsevier, 2010-06)Most metazoan microRNA (miRNA) target sites have perfect pairing to the seed region, located near the miRNA 5′ end. Although pairing to the 3′ region sometimes supplements seed matches or compensates for mismatches, pairing ... -
Expanding the public sphere through computer-mediated communication : political discussion about abortion in a Usenet newsgroup
(Massachusetts Institute of Technology, 1997) -
Expanding the Repertoire of Amyloid Polymorphs by Co-polymerization of Related Protein Precursors
(American Society for Biochemistry and Molecular Biology (ASBMB), 2013-01)Amyloid fibrils can be generated from proteins with diverse sequences and folds. Although amyloid fibrils assembled in vitro commonly involve a single protein precursor, fibrils formed in vivo can contain more than one ... -
Expanding the stoichiometric window for metal cross-linked gel assembly using competition
(Proceedings of the National Academy of Sciences, 2019-10-07)Polymer networks with dynamic cross-links have generated widespread interest as tunable and responsive viscoelastic materials. However, narrow stoichiometric limits in cross-link compositions are typically imposed in the ... -
Expanding the submillimeter wave spectroscopy and astronomical search for thioacetamide (CH3CSNH2) in the ISM
(EDP Sciences, 2022-02)Context. One of the biggest unsolved mysteries of modern astrochemistry is understanding chemical formation pathways in the interstellar medium (ISM) and circumstellar environments. The detections (or even nondetections) ... -
Expanding the substrate scope in palladium-catalyzed C-N and C-C bond-forming reactions
(Massachusetts Institute of Technology, 2006)Chapter 1. The first detailed study of the palladium-catalyzed amination of aryl nonaflates is reported. Use of bulky electron-rich monophosphinobiaryl ligands or BINAP allow for the catalytic amination of electron-rich ... -
Expanding the synthesis of distributed memory implementations
(Massachusetts Institute of Technology, 2015)In this thesis, I expanded the programming model implemented by the Sketch language to supplement its distributed memory parallelism with shared memory parallelism that uses the popular fork-join model. The primary ... -

Expanding transportation planning capacity in cities of the global South : public-private collaboration and conflict in Chile and Mexico
(Massachusetts Institute of Technology, 2013)What makes it possible for the governments of cities limited by scarce fiscal resources and weak institutions to enhance their transportation planning and regulatory capacities so as to provide the public with cleaner, ... -
Expanding ultrafast photoacoustics for investigation of mechanical properties and thermal transport
(Massachusetts Institute of Technology, 2019)To address the need for broadband mechanical spectroscopy, femtosecond laser pulses were used to generate and detect acoustic waves. To expand the acoustic phonon frequency bandwidth and range, a thin metal film, a strongly ... -
Expansion and pricing criteria for ports using a two stage queuing model
(Massachusetts Institute of Technology, 1979) -
Expansion and retraction dynamics in drop-on-drop impacts on nonwetting surfaces
(American Physical Society, 2018-09)Impacts of liquid droplets on other stationary droplets on a surface are ubiquitous in numerous applications such as agricultural sprays, inkjet printing, and rain impact on surfaces. We experimentally study the maximum ... -
Expansion and revision of the production and management facilities of the Royer Foundry and Machine Company
(Massachusetts Institute of Technology, 1949) -
Expansion and shrinkage of early age cementitious materials under saturated conditions : the role of colloidal eigenstresses
(Massachusetts Institute of Technology, 2016)Mixing water with anhydrous cement powder and other additives results in a viscid cement slurry and triggers a set of complex exothermic reactions. As the cement slurry transitions from a suspension to a gel and ultimately ...
