Aqueous Multiphase Systems of Polymers and Surfactants Provide Self-Assembling Step-Gradients in Density
(American Chemical Society, 2012)This Communication demonstrates the generation of over 300 phase-separated systems—ranging from two to six phases—from mixtures of aqueous solutions of polymers and surfactants. These aqueous multiphase systems (MuPSs) ... -
Aqueous-Phase Reactive Uptake of Dicarbonyls as a Source of Organic Aerosol Over Eastern North America
(Elsevier, 2009)We use a global 3-D atmospheric chemistry model (GEOS-Chem) to simulate surface and aircraft measurements of organic carbon (OC) aerosol over eastern North America during summer 2004 (ICARTT aircraft campaign), with the ... -
Aquilegia as a Model System for the Evolution and Ecology of Petals
(Royal Society, 2010)The ranunculid genus Aquilegia holds extraordinary promise as a model system for investigating a wide range of questions relating to the evolution and ecology of petals. New genetic and genomic resources, including an ... -
Arabic diacritization using weighted finite-state transducers
(Association for Computational Linguistics, 2005)Arabic is usually written without short vowels and additional diacritics, which are nevertheless important for several applications. We present a novel algorithm for restoring these symbols, using a cascade of probabilistic ... -
Arbitrage, Factor Structure, and Mean-Variance Analysis on Large Asset Markets
(National Bureau of Economic Research, 1982)We examine the implications of arbitrage in a market with many assets. The absence of arbitrage opportunities implies that the linear functionals that give the mean and cost of a portfolio are continuous; hence there exist ... -
Arc-Length Compression
(2003)We introduce a novel method for lossy compression of the two-dimensional curves based on the arc-length parameterization. We show that the proposed method has a number of advantages: it is progressive, converges uniformly, ... -
Archaea and Fungi of the Human Gut Microbiome: Correlations with Diet and Bacterial Residents
(Public Library of Science, 2013)Diet influences health as a source of nutrients and toxins, and by shaping the composition of resident microbial populations. Previous studies have begun to map out associations between diet and the bacteria and viruses ... -

The Archaeology of the Pueblo Revolt and the Formation of the Modern Pueblo World
(Arizona Archaeological and Historical Society, 2007)The Pueblo Revolt and its aftermath (AD 1680-1696) was a crucial period in the history of the American Southwest. Previous studies of this era have focused primarily on the causes of the Revolt, often casting it as an ... -
Archean Microfossils Showing Cell Division from the Swaziland System of South Africa
(American Association for the Advancement of Science, 1977)A newly discovered population of organic walled microstructures from the Swaziland System, South Africa, is considered to be biological on the following grounds: (i) the structures are carbonaceous and occasionally have ... -
Archean Photoautotrophy: Some Alternatives and Limits
(Springer, 1979)From the Archean geological record, one can infer that photoautotrophy evolved early in earth history; however, the nature of this photosynthesis - whether it was predominantly bacterial or cyanobacterlal - is tess clearly ... -
An Architecture A Day Keeps The Hacker Away
(Association for Computing Machinery, 2005)System security as it is practiced today is a losing battle. In this paper, we outline a possible comprehensive solution for binary-based attacks, using virtual machines, machine descriptions, and randomization to achieve ... -
Architecture and Function of Mechanosensitive Membrane Protein Lattices
(Nature Publishing Group, 2016)Experiments have revealed that membrane proteins can form two-dimensional clusters with regular translational and orientational protein arrangements, which may allow cells to modulate protein function. However, the physical ... -
The Architecture and Pottery of a Late 3rd Millennium BC Residential Quarter at Tell Hamoukar, Northeastern Syria
(British Institute for the Study of Iraq, 2011)The 2001 excavations in Area H on Hamoukar’s lower town produced a wealth of information on a residential neighbourhood of a late third-millennium BC city. The excavations were intended to address several issues, including ... -

Architectures for Real-Time Volume Rendering
(Elsevier, 1999)Over the last decade, volume rendering has become an invaluable visualization technique for a wide variety of applications. This paper reviews three special-purpose architectures for interactive volume rendering: texture ... -
