Automorphisms of Even Unimodular Lattices and Unramified Salem Numbers
(Elsevier, 2002)In this paper we study the characteristic polynomials \(S(x)=\det(xI−F| II_{p,q})\) of automorphisms of even unimodular lattices with signature \((p,q)\). In particular, we show that any Salem polynomial of degree \(2n\) ... -

Automorphy for Some \(l\)-Adic Lifts of Automorphic Mod \(l\) Galois Representations
(Springer Berlin / Heidelberg, 2008)We extend the methods of Wiles and of Taylor and Wiles from \(GL_2\) to higher rank unitary groups and establish the automorphy of suitable conjugate self-dual, regular (de Rham with distinct Hodge-Tate numbers), minimally ... -
Autonomous Dynamic Control of DNA Nanostructure Self-Assembly

Autonomous multistep organic synthesis in a single isothermal solution mediated by a DNA walker
(Nature Publishing Group, 2010)Multistep synthesis in the laboratory typically requires numerous reaction vessels, each containing a different set of reactants. In contrast, cells are capable of performing highly efficient and selective multistep ... -

Autopsy on an Empire: Understanding Mortality in Russia and the Former Soviet Union
(American Economic Association, 2005)Male life expectancy at birth fell by over six years in Russia between 1989 and 1994. Many other countries of the former Soviet Union saw similar declines, and female life expectancy fell as well. Using cross-country and ... -
Autotagging Facebook: Social Network Context Improves Photo Annotation
(Institute of Electrical & Electronics Engineers (IEEE), 2008)Most personal photos that are shared online are embedded in some form of social network, and these social networks are a potent source of contextual information that can be leveraged for automatic image understanding. In ... -
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 ... -

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 ...
