An interactive system for the display and manipulation of molecular surface properties is presented. The property at the molecular surface is mapped onto the sphere by gnomonic projection. This representation allows direct comparison of the surface properties of pairs of molecules. The system allows the user to explore the similarities between a pair of(More)
s initially seemed promising but on closer inspection were found to address virtually none of the literature of the last twenty-five years outside narrow subject areas (e.g. Evans 2011) were quickly discarded. Identifying relevant articles was an iterative process. The cited by tool in Advanced Google Scholar was used in an attempt to minimize the risk of(More)
SPICES (Spectro-Polarimetric Imaging and Characterization of Exoplanetary Systems) is a five-year M-class mission proposed to ESA Cosmic Vision. Its purpose is to image and characterize long-period extrasolar planets and circumstellar disks in the visible (450–900 nm) at a spectral resolution of about 40 using both spectroscopy and polarimetry.

Communicative language teaching (CLT) is promoted in teacher education programmes around the world, although the appropriateness of this methodology in contexts outside the English-speaking West has been questioned, often from a theoretical perspective. In fact, very little empirical research has been conducted into the practical knowledge of CLT of(More)

This paper describes an ultra linear, low power consumption, high/low gain state LNA based on the Gilbert micromixer input stage for use in any modern day wireless communications systems. The LNA was designed for L band operation, and has a simulated performance with these characteristics at 1.9 GHz: Voltage gain of 15 dB, noise figure of 2.60 dB, IIP3 of(More)
We present the first resolved image of the debris disk around the 16±8 Myr old star, HD 114082. The observation was made in the H band using the SPHERE instrument. The star is at a distance of 92±6 pc in the Lower Centaurus Crux association. Using a Markov Chain Monte Carlo analysis, we determined that the debris is likely in the form of a dust ring with an(More)
