A comparative study of the energetics of CO on stepped and kinked Cu surfaces using density functional theory
Faisal Mehmood, Abdelkader Kara, Talat S. Rahman +1
Our ab initio calculations of CO adsorption on several low and high miller index surfaces of Cu show that the adsorption energy increases as the coordination of the adsorption site…
Multiplicity of very low-mass objects in the Upper Scorpius OB association: a possible wide binary population
H. Bouy, E. L. Martin, W. Brandner +5
We report the initial results of a VLT/NACO high spatial resolution imaging survey for multiple systems among 58 M-type members of the nearby Upper Scorpius OB association. Nine pa…
A New Proof on Net Upscale Energy Cascade in 2D and QG Turbulence
Eleftherios Gkioulekas, Ka Kit Tung
A general proof that more energy flows upscale than downscale in two-dimensional (2D) turbulence and barotropic quasi-geostrophic (QG) turbulence is given. A proof is also given th…
Discovery of a nearby M9 dwarf
N. Phan-Bao, M. S. Bessell, E. L. Martin +8
We report the discovery of a new M9.0 dwarf at only 8.2 pc, which we identified in our search for nearby ultracool dwarf (I-J >= 3.0, later than M8.0) in the DENIS database. We mea…
An R||C_{max} Quantum Scheduling Algorithm
Feng Lu, Dan C. Marinescu
Grover's search algorithm can be applied to a wide range of problems; even problems not generally regarded as searching problems, can be reformulated to take advantage of quantum p…
Oversampling generates super-wavelets
Dorin Ervin Dutkay, Palle E. T. Jorgensen
We show that the second oversampling theorem for affine systems generates super-wavelets. These are frames generated by an affine structure on the space $L^2(\br)\oplus...\oplus L^…
