Effect of Vaccination on SARS-CoV-2 Spread
(2023-11-21)The July 2021 Provincetown, Massachusetts, Delta variant outbreak was the first large SARS-CoV-2 outbreak in vaccinated individuals; the Delta wave and the Omicron waves that followed it infected most individuals around ... -
Effective Allocation of Reactive Cholera Vaccines: A One or Two Dose Campaign?
(2015-06-26)Every year for the past five years, over 100,000 cases of cholera have been reported to the World Health Organization (WHO). Though cholera is by no means a new disease, its containment in low-income countries has proved ... -
An effective theory on the light shell
(2014-10-21)We describe work on the construction of an effective field theory on a spherical light shell. The motivation arises from classical electromagnetism: If a collision produces charged particles with zero net charge emerging ... -
Effector roles of Granulocytes and B cells during Th2 Inflammation
(2014-06-06)Allergens are complex mixes of proteins and other compounds that have innate signaling capacity leading to Th2 inflammation. Understanding the role of each of these signals is essential to determining what separates allergens ... -
Effectors of cell death in bacterial antiphage defense
(2022-01-14)Bacteria encode many systems to detect and respond to infection with bacteriophages. Cyclic-oligonucleotide based antiphage signaling systems (CBASS) are widespread antiviral systems encoded in approximately 10% of bacterial ... -
Effects of Matrix Mechanics on Secretion of Leukocyte Chemoattractants From Bone-Marrow Derived Mesenchymal Stromal Cells
(2016-06-21)Recent advances in biology have revealed that inflammation may be a key link between a number of prevalent diseases including cardiovascular disease and cancer. That hypothesis is strengthened by the fact that inflammation ... -
Efferocytosis is an Innate Antibacterial Mechanism of Mycobacterium tuberculosis Control
(2012-12-13)One third of the world’s population is infected with Mycobacterium tuberculosis, causing two million deaths annually. The bacteria avoid immune clearance by persisting within macrophages by subverting normal phagosome ... -
Efficiency in warehouse-scale computers: a datacenter tax study
(2017-01-25)Computation has been steadily migrating from isolated on-premise deployments to the datacenters of a small number of large-scale cloud providers. The datacenters powering the cloud, also known as warehouse-scale computers ... -
Efficient Identification and Dissection of Key Neural Circuits Controlling Behavior Across Different Time Scales
(2021-03-31)A fundamental question in neuroscience is how neural networks generate behavior. The lack of genetic tools and unique promoters to functionally manipulate specific neuronal subtypes makes it challenging to determine the ... -
Efficient Object Localization and Scene Registration Using Contour-Enhanced Point Cloud Resampling Techniques
(2018-06-29)In this thesis, I present an efficient implementation of contour-enhanced graph-based resampling of point clouds. I develop both color-blind and color-aware versions of this technique, which I then apply to the problems ... -
Efficient Passive Ranging with Computational Optics
(2022-01-10)Passive ranging is using the measurement of environmental light to estimate the distance of the nearest reflective surface from a viewpoint along a direction without emitting photons. It outputs a two-dimensional depth map ... -
Efficient Reconstruction and Proofreading of Neural Circuits
(2021-05-14)This thesis presents the design and implementation of software technologies for neural circuit reconstruction in light of a need for radical improvements in efficiency and scalability. It focuses primarily on reconstructing ... -
Efficient RNA Interference in C. Elegans Requires the Putative RNA Helicase RDE-12 and Early Exposure to Double-Stranded RNA
(2017-05-11)RNA interference (RNAi) is a phenomenon in which double stranded RNA (dsRNA) triggers silencing of cognate genes. In the nematode C. elegans, RNAi involves an amplifications step in which abundant secondary short-interfering ... -
eGaIn Sensor for Plantar Arch Measurement
(2015-06-26)An essential part of gait training is providing real-time feedback, which has shown to be effective by allowing runners to identify and correct biomechanical dysfunctions in the leg movement while walking or running. Several ... -
Eichler-Shimura Relations
(2022-05-10)The well-known classical Eichler-Shimura relation for modular curves asserts that the Hecke operator T_p is equal, as an algebraic correspondence over the special fiber, to the sum of Frobenius and Verschiebung. Blasius ... -
The Eigencurve is Proper
(2014-06-06)Coleman and Mazur constructed a rigid analytic curve Cp,N, called the eigencurve, whose points correspond to all finite slope overconvergent p-adic eigenforms. We prove the conjecture that the eigencurve Cp,N is proper ... -
Eighth-Century Anthologies and the Creation of High Tang Poetry
(2022-05-11)The great era of medieval Chinese poetic flourishing known as the High Tang, corresponding roughly to the first half of the eighth century and especially the reign of Emperor Xuanzong (r. 712–756), has been the subject ... -
The Einstein and the Navier-Stokes Equations: Connecting the Two
(2013-02-22)This thesis establishes a precise mathematical connection between the Einstein equations of general relativity and the incompressible Navier-Stokes equation of fluid dynamics. We carry out a holographic analysis which ... -
El centro del Centro: Ficción e ilusión en el Zócalo de la Ciudad de México
(2017-05-13)This study analyzes artistic and cultural productions that have contributed to the construction of Mexican national identity through references to the central national space with the official name of the Plaza of the ... -
Elasticity of Compressed Emulsions
(2014-06-06)The interfaces of bubbles and droplets imbue foams and emulsions with extraordinary mechanical and chemical properties. The remarkably large interfacial area of these structures controls their thermodynamics and makes ...
