1 Bedrov, Dmitro; Smith, Grant D.Anomalous pressure dependence of the structure factor in 1,4-polybutadiene melts: a molecular dynamics simulation studyNeutron scattering has shown the first diffraction peak in the structure factor of a 1,4-polybutadiene melt under compression to move to larger q values as expected but to decrease significantly in intensity. Simulations reveal that this behavior does not result from loss of structure in the polymer...Polymer melts; 1, 4-polybutadiene melts; Pressure; Structure factor2004-07
2 Gondolo, PaoloDetectability of the Sgr dwarf leading tidal stream with Auger, EUSO, or OWLWe point out that if heavy metastable particles composing the dark matter of our galaxy are responsible for the ultrahigh energy cosmic rays (UHECR) then the leading tidal stream of the Sagittarius dwarf galaxy could be detected through UHECR. The signal would be an anisotropy in the UHECR flux sma...Sagittarius dwarf galaxy; Sgr stream; anisotropy2004-07
3 Freire, JulianaManaging XML data: an abridged overviewXML's flexibility makes it a natural format for both exchanging and integrating data from diverse data sources. In this survey, the authors give an overview of issues in managing XML data, discuss existing solutions, and outline the current technology's open problems and limitations.XDM2004-07
4 Wu, Yong-ShiOpen spin chain and open spinning stringIn this letter, we study the open spinning strings and their SYM duals. A new class of folded open spinning strings is found. At planar one-loop level in SYM, by solving the thermodynamic limit of the Bethe ansatz equations for an integrable open spin chain, we find good agreement with string theory...2004-07
5 Hansen, Charles D.; Whitaker, Ross T.Streaming narrow-band algorithm: interactive computation and visualization of level setsAbstract-Deformable isosurfaces, implemented with level-set methods, have demonstrated a great potential in visualization and computer graphics for applications such as segmentation, surface processing, and physically-based modeling. Their usefulness has been limited, however, by their high computa...2004-07
6 Gondolo, PaoloVariable stars toward the bulge of M 31: the AGAPE catalogueWe present the AGAPE astrometric and photometric catalogue of 1579 variable stars in a 14' × 10' field centred on M 31. This work is the first survey devoted to variable stars in the bulge of M 31. The R magnitudes of the objects and the B − R colours suggest that our sample is dominated by red l...M31; AGAPE; X-rays; Cepheids; Novae2004-07
7 Lupton, John MarkVibrational fluorescence spectroscopy of single conjugated polymer moleculesFluorescence spectroscopy of conjugated polymers at the single molecule level provides unique insight into the nature of the emitting state of these organic semiconductors.We are able to verify the picture that molecular excitations form the primary photoexcitations in conjugated polymers by identi...Single molecule; Vibrational fluorescence spectroscopy2004-07
