Efficient generation of jets from magnetically arrested accretion on a rapidly spinning black hole
(Oxford University Press (OUP), 2011)We describe global, 3D, time‐dependent, non‐radiative, general‐relativistic, magnetohydrodynamic simulations of accreting black holes (BHs). The simulations are designed to transport a large amount of magnetic flux to the ... -
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 Image Reconstruction for Gigapixel Quantum Image Sensors
(IEEE, 2014)Recent advances in materials, devices and fabrication technologies have motivated a strong momentum in developing solid-state sensors that can detect individual photons in space and time. It has been envisioned that such ... -
Efficient in vivo base editing via single adeno-associated viruses with size-optimized genomes encoding compact adenine base editors
(Springer Science and Business Media LLC, 2022-07-28)The viral delivery of base editors has been complicated by their size and by the limited packaging capacity of adeno-associated viruses (AAVs). Typically, dual-AAV approaches based on trans-splicing inteins have been used. ... -
Efficient Interdependent Value Combinatorial Auctions with Single Minded Bidders
(AAAI Press, 2013)We study the problem of designing efficient auctions where bidders have interdependent values; i.e., values that depend on the signals of other agents. We consider a contingent bid model in which agents can explicitly ... -
Efficient Isotropic BRDF Measurement
(Eurographics Association, 2003)In this paper we present novel reflectance measurement procedures that require fewer total measurements than standard uniform sampling approaches. First, we acquire densely sampled reflectance data for a large collection ... -
Efficient Kidney Exchange: Coincidence of Wants in a Markets with Compatibility-Based Preferences
(American Economic Association, 2007)Patients needing kidney transplants may have donors who cannot donate to them because of blood or tissue incompatibility. Incompatible patient-donor pairs can exchange donor kidneys with other pairs only when there is a ... -
Efficient Learning of Real Time One-Counter Automata
(1995)We present an efficient learning algorithm for languages accepted by deterministic real time one counter automata (ROCA). The learning algorithm works by first learning an initial segment, Bn, of the infinite state machine ... -
Efficient Mechanisms with Dynamic Populations and Dynamic Types
(Harvard University. Division of Engineering and Applied Physics, 2009)We consider the truthful implementation of an efficient decision policy when agents have dynamic type and are periodically-inaccessible, with agents unable to report information or make payments while inaccessible. This ... -
Efficient Metadeliberation Auctions
(Association for the Advancement of Artificial Intelligence, 2008)Imagine a resource allocation scenario in which the interested parties can, at a cost, individually research ways of using the resource to be allocated, potentially increasing the value they would achieve from obtaining ... -
Efficient methods for one-shot quantum communication
(Springer Science and Business Media LLC, 2022-08-20)We address the question of efficient implementation of quantum protocols, with small communication and entanglement, and short depth circuit for encoding or decoding. We introduce two new methods to achieve this, the first ... -
Efficient Moment-Based Inference of Admixture Parameters and Sources of Gene Flow
(Oxford University Press, 2013)The recent explosion in available genetic data has led to significant advances in understanding the demographic histories of and relationships among human populations. It is still a challenge, however, to infer reliable ... -
Efficient Mutagenesis by Cas9 Protein-Mediated Oligonucleotide Insertion and Large-Scale Assessment of Single-Guide RNAs
(Public Library of Science, 2014)The CRISPR/Cas9 system has been implemented in a variety of model organisms to mediate site-directed mutagenesis. A wide range of mutation rates has been reported, but at a limited number of genomic target sites. To uncover ... -
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 photon detection from color centers in a diamond optical waveguide
(American Physical Society (APS), 2012)A common limitation of experiments using color centers in diamond is the poor photon collection efficiency of microscope objectives due to refraction at the diamond interface. We present a simple and effective technique ... -
Efficient photon triplet generation in integrated nanophotonic waveguides
(The Optical Society, 2016)Generation of entangled photons in nonlinear media constitutes a basic building block of modern photonic quantum technology. Current optical materials are severely limited in their ability to produce three or more entangled ... -
