Phylogeny of the Betulaceae is assessed on the basis of rbcL, ITS, and morphological data. Based upon 26 rbcL sequences representing most "higher" hamamelid families, the Betulaceae are monophyletic, with Casuarinaceae as its sister group, regardless of whether the outgroup is Cunoniaceae, Cercidiphyllaceae, Hamamelidaceae, or Nothofagus. Within the(More)
Ad hoc networks can be formed on highways among moving vehicles, each equipped with a wireless LAN device. However, during times of low traffic density, it is likely that such networks are disconnected. This paper tests the hypothesis that the <i>motion</i> of vehicles on a highway can contribute to successful message delivery, provided that messages can be(More)
The presence of P-glycoprotein in the cell plasma membrane limits the penetration of many cytotoxic substances into cells that express the gene product. There is considerable evidence also to indicate that P-glycoprotein is expressed as part of the normal blood-brain barrier in the luminal membranes of the cerebral capillary endothelial cells, where it(More)
The lasers and waterjets have been used in industry for decades now. The two technologies have procured many overlapping applications and it is thus important for the industry to understand both processes, in order to select the more optimum method in different situations. The comprehensive knowledge on quality and operating cost would help the users to(More)
In this paper, an adaptive predictive multiplicative autoregressive (APMAR) method is proposed for lossless medical image coding. The adaptive predictor is used for improving the prediction accuracy of encoded image blocks in our proposed method. Each block is first adaptively predicted by one of the seven predictors of the JPEG lossless mode and a local(More)
