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)
We present a 128/spl times/32 four-quadrant programmable current-mode analog vector-matrix multiplier (VMM). The proposed multiplier cell operates on a 3.3 V supply, consumes 531 nW/MHz and is linear over two decades of current range. Programmability and non-volatile weight storage is obtained by using floating-gate transistors. Experimental results for a(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)
Grid is an advanced wide area parallel distributed computing environment where unused processor cycles and underutilized storage of numerous computers are utilized efficiently which act as a supercomputer. Security is the most important concern in Grid computing environment. Among all other security issues authentication is the first step of security(More)
