The Bergman-Shelah Preorder on Transformation Semigroups
(2012-11-01)
Let $\nat^\nat$ be the semigroup of all mappings on the natural numbers $\nat$, and let $U$ and $V$ be subsets of $\nat^\nat$. We write $U\preccurlyeq V$ if there exists a countable subset $C$ of $\nat^\nat$ such that $U$ ...
Kierkegaard and the problem of special relationships : Ferreira, Krishek and the 'God filter'
(2012-11)
Kierkegaard’s Works of Love has often been accused of being unable to deal adequately with ‘special relationships’. This debate has re-emerged in a fresh form in a recent disagreement in the secondary literature between ...
AzTEC half square degree survey of the SHADES fields - II : Identifications, redshifts and evidence for large-scale structure
(2012-11-01)
The Astronomical Thermal Emission Camera (AzTEC) 1.1mm survey of the two SCUBA HAlf Degree Extragalactic Survey (SHADES) fields is the largest (0.7 deg ) blank-field millimetre-wavelength (mm-wavelength) survey undertaken ...

The Gaia spectrophotometric standard stars survey. I. Preliminary results
(2012-11-01)
We describe two ground based observing campaigns aimed at building a grid of approximately 200 spectrophotometric standard stars (SPSS), with an internal ~1% precision and tied to Vega within ~3%, for the absolute flux ...
NGC 2207/IC 2163 : A Grazing Encounter with Large-scale Shocks
(2012-11)
Radio continuum, Spitzer infrared, optical, and XMM-Newton X-ray and ultraviolet observations (UVW1 and UVM2) are used to study large-scale shock fronts, young star complexes, and the galactic nuclei in the interacting ...
Remote sensing of chiral signatures on Mars
(2012-11-01)
We describe circular polarization as a remote sensing diagnostic of chiral signatures which may be applied to Mars. The remarkable phenomenon of homochirality provides a unique biosignature which can be amenable to remote ...
Integrated 18F-FDG PET/CT and perfusion CT of primary colorectal cancer : effect of inter- and intraobserver agreement on metabolic-vascular parameters
(2012-11)
The purpose of this article is to assess the effect of observers on combined metabolic-vascular parameters in colorectal cancer. Twenty-five prospective patients (12 men and 13 women; mean age, 66.9 years) with proven ...
Little Things
(2012-11)
We present LITTLE THINGS (Local Irregulars That Trace Luminosity Extremes, The H I Nearby Galaxy Survey), which is aimed at determining what drives star formation in dwarf galaxies. This is a multi-wavelength survey of 37 ...
