Two new homomorphism dualities and lattice operations
(2011)The study of constraint satisfaction problems definable in various fragments of Datalog has recently gained considerable importance. We consider constraint satisfaction problems that are definable in the smallest natural ... -
Two New Planets from the Anglo-Australian Planet Search
(2001-07)Precise Doppler measurements from the Anglo-Australian Telescope (AAT) UCLES spectrometer reveal periodic Keplerian velocity variations in the stars HD 160691 and HD 27442. HD 160691 has a period of 743 days, a semiamplitude ... -
Two new ultracool benchmark systems from WISE+2MASS
(2013-05)We have used the Two-Micron All-Sky Survey and the Wide-field Infrared Survey Explorer to look for ultracool dwarfs that are part of multiple systems containing main-sequence stars. We cross-matched L dwarf candidates from ... -
Two planets around Kapteyn's star: a cold and a temperate super-Earth orbiting the nearest halo red dwarf
(2014-09-01)Exoplanets of a few Earth masses can be now detected around nearby low-mass stars using Doppler spectroscopy. In this Letter, we investigate the radial velocity variations of Kapteyn's star, which is both a sub-dwarf M-star ... -
Two populations are better than one: Short gamma-ray bursts from SGR giant flares and NS-NS mergers
(American Institute of Physics (AIP), 2007)With a peak luminosity of ~ 1047 erg s-1 the December 27th 2004 giant flare from SGR1806-20 would have been visible by BATSE (the Burst and Transient Source Experiment) out to ≈50 Mpc. It is thus plausible that some fraction ... -
Two problems of intersubjectivity
(2009)I propose a distinction between two closely related problems: the problem of social cognition and the problem of participatory sense-making. One problem focuses on how we understand others; the other problem focuses on ... -
Two Strategies to Enhance Ungual Drug Permeation from UV-cured Films: Incomplete Polymerisation to Increase Drug Release and Incorporation of Chemical Enhancers
(2018-10-15)UV-curable gels, which polymerise into long-lasting films upon exposure to UVA, have been identified as potential topical drug carriers for the treatment of nail diseases. Limitations of such films include incomplete drug ... -
Two super-earths orbiting the solar analog HD 41248 on the edge of a 7 : 5 mean motion resonance
(2013-07-01)There are a growing number of multi-planet systems known to be orbiting their host stars with orbital periods that place them in mean motion resonances (MMRs). These systems are generally in first-order resonances and ... -
Two types of calcium channels in single smooth muscle cells from rabbit ear artery - studied with whole cell and single channel recordings
(1987)AB Freshly dispersed rabbit ear artery cells were studied using patch-clamp techniques to measure membrane currents in whole cells and single-channel currents in membrane patches. Whole-cell calcium currents recorded at ... -
Two UK suicides using nicotine extracted from tobacco employing instructions available on the Internet
(2010)Tobacco is one of the most easily accessible and commonly abused drugs world-wide. Nicotine, one of its principal constituents, can cause serious or fatal overdoses. Whilst the deliberate ingestion of this substance appears ... -
Two weather-based models for predicting the onset of seasonal release of ascospores of Leptosphaeria maculans or L-biglobosa
(2007-06)Weather-based models (Improved Blackleg Sporacle and SporacleEzy) to predict the date of onset of seasonal release from oilseed rape debris of ascospores of Leptosphaeria maculans or L. biglobosa, causes of phoma stem ... -
Two Wittgensteins too many: Wittgenstein's foundationalism
(Ashgate Publishing, 2004)In his contribution to this volume, Avrum Stroll makes the assertion that there is ‘a feature of [Wittgenstein's] later philosophy that occurs only in On Certainty. This is a unique form of foundationalism that is neither ... -
Two-component models are of limited value for the assessment of body composition in patients with cirrhosis
(2006)Most techniques for measuring body composition are based on 2-component models (2-CMs) and depend on assumptions relating to the constancy of the density (D(FFM)) and hydration fraction (HF(FFM)) of fat-free mass (FFM). -
A Two-dimensional Analytical Model for Prediction of the Radiation Heat Transfer in Open-cell Metal Foams
(2016-01-25)In this article, a new two-dimensional (2D) explicit analytical model for the evaluation of the radiation heat transfer in highly porous open-cell metal foams is formulated and validated. A correction factor, C, is introduced ... -
A Two-dimensional Frying Model for the Investigation and Optimisation of Continuous Industrial Frying System
(2013-03-01)In this study, a coupled two-dimensional transient model was developed to predict the temperature, moisture content and oil uptake as encountered in industrial continuous deep fryers. The set of transient governing equations ... -
A two-dimensional search for a Gauss-Newton algorithm
(2009)This paper describes a fall-back procedure for use with the Gauss-Newton method for nonlinear least-squares problems. While the basic Gauss-Newton algorithm is often successful, it is well-known that it can sometimes ...
