Accuracy of gastrocnemius muscles forces in walking and running goats predicted by one-element and two-element Hill-type models
(Elsevier BV, 2013)Hill-type models are commonly used to estimate muscle forces during human and animal movement —yet the accuracy of the forces estimated during walking, running, and other tasks remains largely unknown. Further, most ... -
Accurate galactic N(H) values towards quasars and AGN
(IOP Publishing, 1989)Integrated Galactic 21-cm column densities toward about 174 quasars and AGN are presented. The data are corrected for stray radiation, using the technique of Lockman et al. (1986). Because of the 21-arcmin beam size of the ... -
Accurate Measurements of Pointing Performance from In Situ Observations
(Association for Computing Machinery, 2012)We present a method for obtaining lab-quality measurements of pointing performance from unobtrusive observations of natural in situ interactions. Specifically, we have developed a set of user-independent classifiers for ... -
Accurate Path Integration in Continuous Attractor Network Models of Grid Cells
(Public Library of Science, 2009)Grid cells in the rat entorhinal cortex display strikingly regular firing responses to the animal's position in 2-D space and have been hypothesized to form the neural substrate for dead-reckoning. However, errors ... -
Accurate Spectrally Resolved Infrared Radiance Observation from Space: Implications for the Detection of Decade-to-Century–Scale Climatic Change
(American Meteorological Society, 2001-03)The character of data required to measure decade-to-century–scale climatic change is distinctly different from that required for weather prediction or for studies of meteorological processes. The data ought to possess the ... -
Accurate Stellar Population Studies from Multiband Photometric Observations
(American Astronomical Society, 2002)We present a new technique based on multiband near-ultraviolet and optical photometry to measure both the stellar intrinsic properties, i.e., luminosity and effective temperature, and the interstellar dust extinction along ... -
Acetylation of Surface Lysine Groups of a Protein Alters the Organization and Composition of Its Crystal Contacts
(American Chemical Society (ACS), 2016)This paper uses crystals of bovine carbonic anhydrase (CA) and its acetylated variant to examine (i) how a large negative formal charge can be accommodated in protein-protein interfaces, (ii) why lysine residues are often ... -
The achievement of gender parity in a large astrophysics research centre
(Springer Science and Business Media LLC, 2023-11-16)In Australian astronomy, women's representation remains at historic lows, despite a decade of initiatives aimed at improving the representation and support of women in astronomy and academia more generally. Drawing from ... -
Achieving a Strongly Temperature-Dependent Casimir Effect
(American Physical Society, 2010)We propose a method of achieving large temperature T sensitivity in the Casimir force that involves measuring the stable separation between dielectric objects immersed in a fluid. We study the Casimir force between slabs ... -
Achieving Budget-Balance with Vickrey-Based Payment Schemes in Exchanges
(2001)Generalized Vickrey mechanisms have received wide attention in the literature because they are efficient and strategy-proof, i.e. truthful bidding is optimal whatever the bids of other agents. However it is well-known that ... -
Achieving Escape Velocity: Neighborhood and School Interventions to Reduce Persistent Inequality
(American Economic Association, 2013)This paper reviews the evidence on the efficacy of neighborhood and school interventions in improving the long-run outcomes of children growing up in poor families. We focus on studies exploiting exogenous sources of ... -
Achieving High Throughput Ground-to-UAV Transport via Parallel Links
(IEEE, 2011)Wireless data transfer under high mobility, as found in unmanned aerial vehicle (UAV) applications, is a challenge due to varying channel quality and extended link outages. We present FlowCode, an easily deployable link-layer ... -
Achieving the Middle Ground in an Age of Concentrated Extremes: Mixed Middle-Income Neighborhoods and Emerging Adulthood
(SAGE Publications, 2015)This paper focuses on stability and change in “mixed middle-income” neighborhoods. We first analyze variation across nearly two decades for all neighborhoods in the U.S. and the Chicago area. We then analyze a new ... -
Achieving Trust without Disclosure: Dark Pools and a Role for Secrecy-Preserving Verification
(2015)Can an exchange be “dark,” so that orders are not displayed, while simultaneously trustworthy, so that the execution of trades and flow of information occur as promised? SEC actions against dark pools suggest cause for ... -
Achiral symmetry breaking and positive Gaussian modulus lead to scalloped colloidal membranes
(2017)In the presence of a non-adsorbing polymer, monodisperse rod-like particles assemble into colloidal membranes, which are one rod-length thick liquid-like monolayers of aligned rods. Unlike 3D edgeless bilayer vesicles, ... -
