Applying Wet Sieving Fecal Particle Size Measurement to Frugivores: A Case Study of the Eastern Chimpanzee (Pan Troglodytes Schweinfurthii)
(Wiley, 2017-04-04)Fecal particle size (FPS) as quantified by wet sieving analysis is a measure of chewing efficiency relevant for the understanding of physiological adaptations and constraints in herbivores. FPS has not been investigated ... -
An Appreciation of Christiane Groeben: The Correspondence between Charles Darwin and Anton Dohrn

Approaching the intrinsic band gap in suspended high-mobility graphene nanoribbons
(American Physical Society, 2011)We report electrical transport measurements on a suspended ultra-low-disorder graphene nanoribbon (GNR) with nearly atomically smooth edges that reveal a high mobility exceeding 3000 cm(2) V-1 s(-1) and an intrinsic band ... -
Appropriate Growth Policy: A Unifying Framework
(MIT Press, 2006)In this lecture, we use Schumpeterian growth theory, where growth comes from quality-improving innovations, to elaborate a theory of growth policy and to explain the growth gap between Europe and the US. Our theoretical ... -
The Appropriation of Native Status: Forming and Reforming Insiders and Outsiders in the Spanish Colonial World
(Max Planck Institut fur europaische Rechtsgeschichte, 2014)This article examines the different meanings of native status in Spanish America. It argues that the classification of Indigenous peoples as »natives« was not meant to reflect a reality of indigeneity as many have assumed, ... -
Approval Voting Behavior in Doodle Polls
(2014)Doodle is a simple and popular online system for scheduling events. It is an implementation of the approval voting mechanism, where candidates are the time slots and each responder approves a subset of the slots. We analyze ... -
Approximate and Compensate: A Method for Risk-Sensitive Meta-Deliberation and Continual Computation
(Association for the Advancement of Artificial Intelligence, 2001)We present a flexible procedure for a resource-bounded agent to allocate limited computational resources to on-line problem solving. Our APPROXIMATE AND COMPENSATE methodology extends a well-known greedy time-slicing ... -
An approximate dual-self model and paradoxes of choice under risk
(Elsevier BV, 2014)We derive a simplified version of the model of Fudenberg and Levine, 2006 and Fudenberg and Levine, 2011 and show how this approximate model is useful in explaining choice under risk. We show that in the simple case of ... -
Approximate Strategyproofness
(Indian Academy of Sciences, 2012)The standard approach of mechanism design theory insists on equilibrium behavior by participants. This assumption is captured by imposing incentive constraints on the design space. But in bridging from theory to practice, ... -
Approximately Efficient Online Mechanism Design
(Massachusetts Institute of Technology Press, 2004)Online mechanism design (OMD) addresses the problem of sequential decision making in a stochastic environment with multiple self-interested agents. The goal in OMD is to make value-maximizing decisions despite this ... -
Approximately-Strategyproof and Tractable Multi-Unit Auctions
(Elsevier, 2005)We present an approximately-efficient and approximately-strategyproof auction mechanism for a single-good multiunit allocation problem. The bidding language allows marginal-decreasing piecewise-constant curves and ... -
Approximating the Shapley Value via Multi-Issue Decomposition
(ACM, 2014)The Shapley value provides a fair method for the division of value in coalitional games. Motivated by the application of crowdsourcing for the collection of suitable labels and features for regression and classification ... -
An aptamer-functionalized chemomechanically modulated biomolecule catch-and-release system
(Nature Publishing Group, 2015)The efficient extraction of (bio)molecules from fluid mixtures is vital for applications ranging from target characterization in (bio)chemistry to environmental analysis and biomedical diagnostics. Inspired by biological ... -
Aquatic and terrestrial takeoffs require different hindlimb kinematics and muscle function in mallard ducks
(The Company of Biologists, 2020-06-25)Mallard ducks are capable of performing a wide range of behaviors including nearly vertical takeoffs from both terrestrial and aquatic habitats. The hindlimb plays a key role during takeoffs from both media. However, because ... -
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 ...
