Auxiliary-boson and DMFT studies of bond ordering instabilities of t-J-V models on the square lattice
(Springer Science + Business Media, 2014)We examine the influence of strong on-site Coulomb interactions on instabilities of the metallic state on the square lattice to general forms of bond order. The Mott correlations are accounted for by the auxiliary-boson ... -
AvaDrone: An Autonomous Drone for Avalanche Victim Recovery
(2015-04-08)For the 179 Americans that are caught in avalanches each year, timely recovery often means the difference between life and death. The goal of this project was to design and build a prototype drone for a system to quickly ... -
Availability and utilization of cardiovascular fixed-dose combination drugs in the United States
(Elsevier BV, 2015)BACKGROUND: Solid clinical evidence supports the effectiveness and safety of multiple drugs in treating diabetes, dyslipidemia, and hypertension, and numerous fixed-dose combination products (FDCs) containing such drugs ... -
Average Marginal Tax Rates from Social Security and the Individual Income Tax
(University of Chicago Press, 1986)We extend previous estimates of the average marginal tax rate from the federal individual income tax to include social security. Our computations consider the tax rates on employers, employees, and the self-employed; the ... -
Average Ranks of Elliptic Curves: Tension between Data and Conjecture
(American Mathematical Society, 2007)Rational points on elliptic curves are the gems of arithmetic: they are, to diophantine geometry, what units in rings of integers are to algebraic number theory, what algebraic cycles are to algebraic geometry. A rational ... -
Average Spectra of Massive Galaxies in the Sloan Digital Sky Survey
(IOP Publishing, 2003)We combine Sloan Digital Sky Survey spectra of 22,000 luminous, red, bulge-dominated galaxies to get high signal-to-noise ratio average spectra in the rest-frame optical and ultraviolet (2600-7000 Å). The average spectra ... -
Avian Egg Shape: Form, Function, and Evolution
(American Association for the Advancement of Science (AAAS), 2017-06-22)Avian egg shape is generally explained as an adaptation to life history, yet we currently lack a global synthesis of how egg-shape differences arise and evolve. Here, we apply morphometric, mechanistic, and macroevolutionary ... -
The Avian Shoulder: An Experimental Approach
(Oxford University Press (OUP), 1989-02) -
Avoiding pathologies in very deep networks
(Journal of Machine Learning Research, 2014)Choosing appropriate architectures and regularization strategies of deep networks is crucial to good predictive performance. To shed light on this problem, we analyze the analogous problem of constructing useful priors on ... -
Avoiding Randomization Failure in Program Evaluation, with Application to the Medicare Health Support Program
(Mary Ann Liebert, 2011)We highlight common problems in the application of random treatment assignment in large-scale program evaluation. Random assignment is the defining feature of modern experimental design, yet errors in design, implementation, ... -
Awake, Offline Processing during Associative Learning
(Public Library of Science, 2016)Offline processing has been shown to strengthen memory traces and enhance learning in the absence of conscious rehearsal or awareness. Here we evaluate whether a brief, two-minute offline processing period can boost ... -
An Axiomatic Characterization of Continuous-Outcome Market Makers
(Springer Verlag, 2010)Most existing market maker mechanisms for prediction markets are designed for events with a finite number of outcomes. All known attempts on designing market makers for forecasting continuous-outcome events resulted in ... -
An axiomatic characterization of wagering mechanisms
(Elsevier BV, 2015)We construct a budget-balanced wagering mechanism that flexibly extracts information about event probabilities, as well as the mean, median, and other statistics from a group of individuals whose beliefs are immutable to ... -
Axiomatic Foundations of Multiplier Preferences
(The Econometric Society, 2011)This paper axiomatizes the robust control criterion of multiplier preferences introduced by Hansen and Sargent (2001). The axiomatization relates multiplier preferences to other classes of preferences studied in decision ... -
Axiomatization and Measurement of Quasi-Hyperbolic Discounting
(Oxford University Press (OUP), 2014)This article provides an axiomatic characterization of quasi-hyperbolic discounting and a more general class of semi-hyperbolic preferences. We impose consistency restrictions directly on the intertemporal trade-offs by ... -
Axion experiments to algebraic geometry — Testing quantum gravity via the Weak Gravity Conjecture
(World Scientific Pub Co Pte Lt, 2016)Common features of known quantum gravity theories may hint at the general nature of quantum gravity. The absence of continuous global symmetries is one such feature. This inspired the Weak Gravity Conjecture, which bounds ... -

Axionic Black Holes and an Aharonov-Bohm Effect for Strings
(American Physical Society, 1988) -
The Axis of Progression of Disease
(Libertas Academica, 2014)Starting with genetic or environmental perturbations, disease progression can involve a linear sequence of changes within individual cells. More often, however, a labyrinth of branching consequences emanates from the initial ... -
AXIS: Generating Explanations at Scale with Learnersourcing and Machine Learning
(2016)While explanations may help people learn by providing information about why an answer is correct, many problems on online platforms lack high-quality explanations. This paper presents AXIS (Adaptive eXplanation Improvement ...
