Accelerating MCMC with Parallel Predictive Prefetching
(AUAI Press, 2014)Parallel predictive prefetching is a new frame- work for accelerating a large class of widely- used Markov chain Monte Carlo (MCMC) algorithms. It speculatively evaluates many potential steps of an MCMC chain in parallel ... -
Accelerating Neoproterozoic research through scientific drilling

Accelerating Resolution-of-the-Identity Second Order Møller-Plesset Quantum Chemistry Calculations with Graphical Processing Units
(American Chemical Society, 2008)The modification of a general purpose code for quantum mechanical calculations of molecular properties (Q-Chem) to use a graphical processing unit (GPU) is reported. A 4.3x speedup of the resolution-of-the-identity ... -
Acceleration of galactic supershells by Lyα radiation
(Oxford University Press, 2009)Scattering of Ly alpha photons by neutral hydrogen gas in a single outflowing 'supershell' around star-forming regions often explains the shape and offset of the observed Ly alpha emission line from galaxies. We compute ... -
Accelerations of Water Masers in NGC 4258
(IOP Publishing, 2000)The water masers in NGC4258 delineate the structure and dynamics of a sub-parsec-diameter accretion disk around a supermassive black hole. VLBA observations provide precise information about the positions in the plane of ... -
The accelerator store
(Association for Computing Machinery (ACM), 2012)In recent years, circuit reliability in modern high-performance processors has become increasingly important. Shrinking feature sizes and diminishing supply voltages have made circuits more sensitive to microprocessor ... -
An Accelerator-Based Wireless Sensor Network Processor in 130 nm CMOS
(Institute of Electrical & Electronics Engineers (IEEE), 2011)Networks of ultra-low-power nodes capable of sensing, computation, and wireless communication have applications in medicine, science, industrial automation, and security. Reducing power consumption requires the development ... -
Acceptance of Mobile Technology by Older Adults: A Preliminary Study
(2016)Mobile technologies offer the potential for enhanced healthcare, especially by supporting self-management of chronic care. For these technologies to impact chronic care, they need to work for older adults, because the ... -
Accepting difference, seeking common ground: Sino-Indian statistical exchanges 1951–1959
(Cambridge University Press (CUP), 2016)Starting as early as 1951, and with increasing urgency after 1956, Chinese and Indian statisticians traded visits as they sought to learn from each other's experiences. At the heart of these exchanges was the desire to ... -
Accessible Mutational Trajectories for the Evolution of Pyrimethamine Resistance in the Malaria Parasite Plasmodium Vivax
(Springer Science + Business Media, 2013)Antifolate antimalarials, such as pyrimethamine, have experienced a dramatic reduction in therapeutic efficacy as resistance has evolved in multiple malaria species. We present evidence from one such species, Plasmodium ... -
Accessing Developmental Information of Fossil Hominin Teeth Using New Synchrotron Microtomography-Based Visualization Techniques of Dental Surfaces and Interfaces
(Public Library of Science, 2015)Quantification of dental long-period growth lines (Retzius lines in enamel and Andresen lines in dentine) and matching of stress patterns (internal accentuated lines and hypoplasias) are used in determining crown formation ... -
Accidental Outcomes Guide Punishment in a 'Trembling Hand' Game
(Public Library of Science, 2009)How do people respond to others' accidental behaviors? Reward and punishment for an accident might depend on the actor's intentions, or instead on the unintended outcomes she brings about. Yet, existing paradigms in ... -
Accounting for Cognitive Costs in On-Line Auction Design
(Springer Verlag, 1999)Many auction mechanisms, including first and second price ascending and sealed bid auctions, have been proposed and analyzed in the economics literature. We compare the usefulness of different mechanisms for on-line auctions, ... -
Accounting for Experimental Noise Reveals That mRNA Levels, Amplified by Post-Transcriptional Processes, Largely Determine Steady-State Protein Levels in Yeast
(Public Library of Science, 2015)Cells respond to their environment by modulating protein levels through mRNA transcription and post-transcriptional control. Modest observed correlations between global steady-state mRNA and protein measurements have been ... -
Accounting for inhomogeneous broadening in nano-optics by electromagnetic modeling based on Monte Carlo methods
(Proceedings of the National Academy of Sciences, 2014)Many experimental systems consist of large ensembles of uncoupled or weakly interacting elements operating as a single whole; this is particularly the case for applications in nano-optics and plasmonics, including colloidal ... -
Accounting Mechanisms for Distributed Work Systems
(AAAI Press, 2010)In distributed work systems, individual users perform work for other users. A significant challenge in these systems is to provide proper incentives for users to contribute as much work as they consume, even when monitoring ... -
Accretion Models of Gamma‐Ray Bursts
(American Astronomical Society, 2001)Many models of gamma-ray bursts (GRBs) involve accretion onto a compact object, usually a black hole, at a mass accretion rate on the order of a fraction of a solar mass per second. If the accretion disk is larger than a ... -
Acculturation and Endocrine Disrupting Chemical-Associated Personal Care Product Use Among US-Based Foreign-Born Chinese Women of Reproductive Age
(Springer Science and Business Media LLC, 2020-11-24)Background: Personal care products (PCPs) are an important source of endocrine disrupting chemicals (EDCs) linked to adverse reproductive health outcomes. Objective: We evaluated EDC-associated PCP use and acculturation ... -
Accumulated Pension Collars: A Market Approach to Reducing The Risk of Investment-Based Social Security Reform
(National Bureau of Economic Research, 2000)This paper shows how a new type of derivative product that could be provided by private financial markets could in principle be used to guarantee that an investment-based Social Security reform provides at least the level ... -
Accumulated tidal heating of stars over multiple pericentre passages near SgrA*
(Oxford University Press, 2013)We consider the long-term tidal heating of a star by the supermassive black hole at the Galactic centre, SgrA*. We show that gravitational interaction with background stars leads to a linear growth of the tidal excitation ...
