Origins of scaling in genetic code
(2011)
The principle of least effort in communications has been shown, by Ferrer i Cancho and Sol´e, to explain emergence of power laws (e.g., Zipf’s law) in human languages. This paper applies the principle and the informationtheoretic ...
Submillimetre galaxies reside in dark matter haloes with masses greater than 3 x 10(11) solar masses
(2011)
The extragalactic background light at far-infrared wavelengths(1-3) comes from optically faint, dusty, star-forming galaxies in the Universe with star formation rates of a few hundred solar masses per year(4). These faint, ...
Journalists' collective representation and editorial content in newspapers
(2011)
Purpose : This article examines the intriguing juxtaposition of a bona fide independent union for journalists in Britain which is vocal about editorial standards and interference yet has seldom taken collective action to ...
What is the innovation beyond the 'state of the art' in e-learning?
(2011)
The motivation for this discussion paper comes from the recent FP7 framework ICT call for technology-enhanced learning applications for the 21st century that go beyond the current “state of the art” in e-learning. In this ...
The edge of the milky way stellar disk revealed using clump giant stars as distance indicators
(2011)
We use the clump giants of the disk as standard candles calibrated from Hipparcos parallaxes in order to map their distribution with two new near-infrared surveys of the Galactic plane: UKIDSS-GPS and VISTA Variables in ...
Influences on the fraction of hydrophobic and hydrophilic black carbon in the atmosphere
(2011)
Black carbon (BC) is a short term climate forcer that directly warms the atmosphere, slows convection, and hinders quantification of the effect of greenhouse gases on climate change. The atmospheric lifetime of BC particles ...
The MUCHFUSS project - Searching for hot subdwarf binaries with massive unseen companions : survey, target selection and atmospheric parameters
(2011)
The project Massive Unseen Companions to Hot Faint Underluminous Stars from SDSS (MUCHFUSS) aims at finding sdBs with compact companions like supermassive white dwarfs (M > 1.0M⊙), neutron stars or black holes. The existence ...
