The SAURON project – XVII. Stellar population analysis of the absorption line strength maps of 48 early-type galaxies
(2010)
We present a stellar population analysis of the absorption line strength maps for 48 early-type galaxies from the SAURON sample. Using the line strength index maps of Hβ, Fe5015 and Mg b, measured in the Lick/IDS system ...
Bio-inspired binary bees algorithm for a two-level distribution optimisation problem
(2010)
Two uncoupleable distributions, assigning missions to robots and allocating robots to home stations, accompany the use of mobile service robots in hospitals. In the given problem, two workload-related objectives and five ...
Spectropolarimetric evidence for a kicked supermassive black hole in the quasar E1821+643
(2010)
We report spectropolarimetric observations of the quasar E1821+643 (z = 0.297), which suggest that it may be an example of gravitational recoil due to anisotropic emission of gravitational waves following the merger of a ...
A search for molecules in the atmosphere of HD 189733b
(2010)
We use signal enhancement techniques and a matched filter analysis to search for the K-band spectroscopic absorption signature of the close orbiting extrasolar giant planet, HD 189733b. With time-series observations taken ...
Discovery of the first L dwarf plus giant binary system and eight other ultracool dwarfs in wide binaries
(2010)
We identify 806 ultracool dwarfs (of which 34 are newly discovered L dwarfs) from their Sloan Digital Sky Survey (SDSS) riz photometry and obtain proper motions through cross-matching with the United Kingdom Infrared ...
Error-Resilient Scheme for Wavelet Video Codec Using Automatic ROI Detection and Wyner-Ziv Coding Over Packet Erasure Channel
(2010)
The error-resilient for video transmission over the Internet in which regarded as the packet erasure channel is always a tough task and has gained lots of attentions. The main contradictory problem lies between error-resilient ...
Extended High Circular Polarization in the Orion Massive Star Forming Region: Implications for the Origin of Homochirality in the Solar System
(2010)
We present a wide-field (∼6′ × 6′) and deep near-infrared (K s band: 2.14 μm) circular polarization image in the Orion nebula, where massive stars and many low-mass stars are forming. Our results reveal that a high circular ...
Neutron cross-sections for next generation reactors : New data from n_TOF
(2010)
In 2002, an innovative neutron time-of-flight facility started operation at CERN: n_TOF. The main characteristics that make the new facility unique are the high instantaneous neutron flux, high resolution and wide energy ...
Genetic algorithms and their application to in silico evolution of genetic regulatory networks
(2010)
A genetic algorithm (GA) is a procedure that mimics processes occurring in Darwinian evolution to solve computational problems. A GA introduces variation through "mutation" and "recombination" in a "population" of possible ...
