1.25 Approximation Algorithm for the Steiner Tree Problem with Distances One and Two
Piotr Berman, Marek Karpinski, Alex Zelikovsky
We give a 1.25 approximation algorithm for the Steiner Tree Problem with distances one and two, improving on the best known bound for that problem.
The long-period Galactic Cepheid RS Puppis - I. A geometric distance from its light echoes
Pierre Kervella, Antoine Mérand, Laszlo Szabados +4
Context: The bright southern Cepheid RS Pup is surrounded by a circumstellar nebula reflecting the light from the central star. The propagation of the light variations from the Cep…
Dihadron azimuthal correlations in Au+Au collisions at sqrt(s_NN)=200 GeV
PHENIX Collaboration, A. Adare
Azimuthal angle (Delta phi) correlations are presented for a broad range of transverse momentum (0.4 < pT < 10 GeV/c) and centrality (0-92%) selections for charged hadrons from di-…
Quantitative Constraints on the Transport Properties of Hot Partonic Matter from Semi-Inclusive Single High Transverse Momentum Pion Suppression in Au+Au collisions at sqrt(s_NN) = 200 GeV
PHENIX Collaboration, A. Adare
The PHENIX experiment has measured the suppression of semi-inclusive single high transverse momentum pi^0's in Au+Au collisions at sqrt(s_NN) = 200 GeV. The present understanding o…
