General Bound on the Rate of Decoherence
(2011)We establish the necessary and sufficient conditions for a quantum system to be stable under any general system-environment interaction. Quantum systems are stable when the time-derivative of their purity is zero. This ... -
A general cartographic labeling algorithm
(University of Toronto Press, 1996)Some apparently powerful algorithms for automatic label placement on maps use heuristics that capture considerable cartographic expertise but are hampered by provably inefficient methods of search and optimization. On the ... -
General circulation model assessment of direct radiative forcing by the sulfate-nitrate-ammonium-water inorganic aerosol system
(Wiley-Blackwell, 2001)An on-line simulation of aerosol sulfate, nitrate, ammonium, and water in the Goddard Institute for Space Studies general circulation model (GCM II-prime) has been used to estimate direct aerosol radiative forcing for the ... -
General Circulation of the Eastern Mediterranean
(Elsevier, 1992)A novel description of the phenomenology of the Eastern Mediterranean is presented based upon a comprehensive pooled hydrographic data base collected during 1985–1987 and analyzed by cooperating scientists from several ... -
The general fault in our fault lines
(Springer Science and Business Media LLC, 2021-04-22)A pervading global narrative suggests that political polarisation is increasing in the US and around the world. Beliefs in increased polarisation impact individual and group behaviours regardless of whether they are accurate ... -
A General Importance Sampling Algorithm for Probabilistic Programs
(2007)Highly expressive probabilistic modeling languages are capable of describing a wide variety of models. Some of these models are quite complex, so approximate inference algorithms are needed. One approach to approximate ... -
General Intelligence in Another Primate: Individual Differences across Cognitive Task Performance in a New World Monkey (Saguinus Oedipus)
(Public Library of Science, 2009)Background: Individual differences in human cognitive abilities show consistently positive correlations across diverse domains, providing the basis for the trait of “general intelligence” (g). At present, little is known ... -
The General Point of View: Love and Moral Approval in Hume's Ethics
(Oxford University Press, 2008)Hume thinks moral judgments are based on sentiments of approval and disapproval we feel when we contemplate someone from a “general point of view.” But why do we take up the general point of view? Hume argues that we take ... -
General Purpose Computer-Assisted Clustering and Conceptualization
(Proceedings of the National Academy of Sciences, 2011)We develop a computer-assisted method for the discovery of insightful conceptualizations, in the form of clusterings (i.e., partitions) of input objects. Each of the numerous fully automated methods of cluster analysis ... -
General Purpose Technology and Wage Inequality
(Springer Science + Business Media, 2002)The recent changes in the US wage structure are often linked to the new wave of capital-embodied information technologies. The existing literature has emphasized either the accelerated pace or the skill-bias of embodied ... -
General Quantitative Relations Linking Cell Growth and the Cell Cycle in Escherichia Coli
(Springer Science and Business Media LLC, 2020-05-18)Growth laws emerging from studies of cell populations provide essential constraints on global mechanisms coordinating cell growth. The foundation of bacterial cell cycle studies, based on extensive work done in Escherichia ... -
General Relativistic Constraints on Emission Models of Anomalous X‐Ray Pulsars
(American Astronomical Society, 2001)Most models of anomalous X-ray pulsars (AXPs) account for the observed X-ray spectra and pulsations by means of radiation processes that occur on the surfaces of neutron stars. For any such model, general relativistic ... -
General relativistic magnetohydrodynamic simulations of Blandford-Znajek jets and the membrane paradigm
(Oxford University Press (OUP), 2013)Recently it has been observed that the scaling of jet power with black hole spin in galactic X-ray binaries is consistent with the predictions of the Blandford-Znajek (BZ) jet model. These observations motivate us to revisit ... -
General Relativistic Modeling of Magnetized Jets from Accreting Black Holes
(Institute of Physics, 2012)Recent advances in general relativistic magnetohydrodynamic modeling of jets offer unprecedented insights into the inner workings of accreting black holes that power the jets in active galactic nuclei (AGN) and other ... -
A General SNP-Based Molecular Barcode for Plasmodium Falciparum Identification and Tracking
(BioMed Central, 2008)Background: Single nucleotide polymorphism (SNP) genotyping provides the means to develop a practical, rapid, inexpensive assay that will uniquely identify any Plasmodium falciparum parasite using a small amount of DNA. ... -
A general statistical framework for designing strategy-proof assignment mechanisms
(2016)We develop a statistical framework for the design of a strategy-proof assignment mechanism that closely approximates a target outcome rule. The framework can handle settings with and without money, and allows the designer ... -
A General Strategy for the Evolution of Bond-Forming Enzymes Using Yeast Display
(Proceedings of the National Academy of Sciences, 2011)The ability to routinely generate efficient protein catalysts of bond-forming reactions chosen by researchers, rather than nature, is a long-standing goal of the molecular life sciences. Here, we describe a directed evolution ... -
A general strategy to construct small molecule biosensors in eukaryotes
(eLife Sciences Publications, Ltd, 2015)Biosensors for small molecules can be used in applications that range from metabolic engineering to orthogonal control of transcription. Here, we produce biosensors based on a ligand-binding domain (LBD) by using a method ... -
General synthesis of complex nanotubes by gradient electrospinning and controlled pyrolysis
(Nature Pub. Group, 2015)Nanowires and nanotubes have been the focus of considerable efforts in energy storage and solar energy conversion because of their unique properties. However, owing to the limitations of synthetic methods, most inorganic ... -
A General-Purpose Provenance Library
(USENIX Associaiton, 2012)Most provenance capture takes place inside particular tools - a workflow engine, a database, an operating system, or an application. However, most users have an existing toolset - a collection of different tools that work ...
