A system for cone-beam computed tomography (CBCT) based on a flat-panel imager (FPI) is used to examine the magnitude and effects of x-ray scatter in FPI-CBCT volume reconstructions. The system is being developed for application in image-guided therapies and has previously demonstrated spatial resolution and soft-tissue visibility comparable or superior to a conventional CT scanner under condit...
In this paper, we propose a new feature extraction method for regression problems. It is a modified version of linear discriminant analysis (LDA) which is a very successful feature extraction method for classification problems. In the proposed method, the between class and the within class scatter matrices in LDA are modified so that they fit in regression problems. The samples with small diffe...
there has been a gradual shift of focus from the study of rule systems, which have increasingly been regarded as impoverished, … to the study of systems of principles, which appear to occupy a much more central position in determining the character and variety of possible human languages. there is a set of absolute universals, notions and principles existing in ug which do not vary from one ...
We have previously shown that, in mouse NIH/3T3 cells, it is necessary to coexpress the gene for human hepatocyte growth factor/scatter factor (HGF/SFhu) with its receptor, the human met protooncogene (methu), to activate the transforming activity of the receptor (S. Rong, M. Bodescot, D. Blair, T. Nakamura, K. Mizuno, M. Park, A. Chan, S. Aaronson, and G. F. Vande Woude, Mol. Cell. Biol., 12: ...
