The human oxytocin receptor includes three N-glycosylation sites in its extracellular N-terminal domain. We have established permanent cell-lines in which the gene for the human oxytocin receptor (OTR) has been introduced into HeLa cells. These cells differ by the disruption of one or more of the N-terminal N-glycosylation sites by site-directed mutagenesis(More)
This paper presents a new neural network (NN) scheme for recovering three dimensional (3D) transparent surface. We view the transparent surface modeling, not as a separate problem, but as an extension of opaque surface modeling. The main insight of this work is we simulate transparency not only for generating visually realistic images, but for recovering(More)
This paper presents a combinatorial (decision tree induction) technique for transparent surface modeling from polarization images. This technique simultaneously uses the object's symmetry, brewster angle, and degree of polarization to select accurate reference points. The reference points contain information about surface's normals position and direction at(More)
