  • Ocean internal wave spectra inferred from seismic reflection transects 

    Holbrook, W. Steven; Fer, Ilker (American Geophysical Union, 2005-08-06)
    Internal waves affect many important dynamical processes in the ocean, but in situ observations of internal waves are infrequent and spatially sparse. Here we show that remote sensing of internal waves by marine seismic ...

  • Of tests, trochs, shells, and spicules: Development of the basal mollusk Wirenia argentea (Solenogastres) and its bearing on the evolution of trochozoan larval key features 

    Todt, Christiane; Wanninger, Andreas (BioMed Central, 2010-01-26)
    Background The phylogenetic status of the aplacophoran mollusk taxon Solenogastres (Neomeniomorpha) is controversially discussed. Some authors propose the clade to represent the most basal branch within Mollusca, while ...

  • On Semi-implicit Splitting Schemes for the Beltrami Color Image Filtering 

    Rosman, Guy; Dascal, Lorina; Tai, Xue-Cheng; Kimmel, Ron (Springer, 2011-01-15)
    The Beltrami flow is an efficient nonlinear filter, that was shown to be effective for color image processing. The corresponding anisotropic diffusion operator strongly couples the spectral components. Usually, this ...
