The indolic compound auxin regulates virtually every aspect of plant growth and development, but its role in embryogenesis and its molecular mechanism of action are not understood. We describe two mutants of Arabidopsis that define a novel gene called AUXIN-RESISTANT6 (AXR6) which maps to chromosome 4. Embryonic development of the homozygous axr6 mutants is(More)
Little is known about the large ectodomain of MET, the product of the c-met protooncogene and receptor for hepatocyte growth factor/scatter factor (HGF/SF). Here, we establish by deletion mutagenesis that the HGF/SF and heparin-binding sites of MET are contained within a large N-terminal domain spanning the alpha-chain (amino acids 25-307) and the first 212(More)
DEDICATION To my parents and my brother ACKNOWLEDGEMENTS I wish to gratefully acknowledge my advisor, Dr. Paul Hasler, for helping me during my stay at Gatech, providing an opportunity, guiding my research and reviewing this thesis. I also want to thank Dr. and Dr. Mark Smith for all the discussions we had and for reviewing this thesis. Many thanks also to(More)
In neuromorphic modeling of the retina, it would be very nice to have processing capabilities at the focal plane while retaining the density of typical active pixel sensor (APS) imager designs. Unfortunately, these two goals have been mostly incompatible. We introduce our transform imager technology and basic architecture that uses analog floating-gate(More)
