Abstract: The invention is a novel family of polyolefins characterized by chain-walking defects of the type that add extra backbone carbons per monomer. These polyolefins display a large decrease in crystallinity relative to polyolefins known in the art. Specifically, the reduction in crystallinity is much greater than for earlier polypropylenes with a matched content of stereo or 1-alkene type defects. The claimed polyolefins can be made by a diimine-based catalyst. The defects in the polyolefin backbone are generated by a chain walking mechanism in which three or more carbons per monomer are added to the polymer backbone instead of two, as in conventional polymerization or copolymerization methods of alpha olefins. The novel polyolefins can be used in applications such as plastic wrapping, thin films, co-extrusion layers or molded parts in the absence of polymer blending or copolymerization. The cost of materials production can be reduced.

Abstract: Memory demands of large-memory applications continue to remain one step ahead of the improvements in DRAM capacities of commodity systems. Performance of such applications degrades rapidly once the system hits the physical memory limit and starts paging to the local disk. A distributed network-based virtual memory scheme is provided which treats remote memory as another level in the memory hierarchy between very fast local memory and very slow local disks. Performance over gigabit Ethernet shows significant performance gains over local disk. Large memory applications may access potentially unlimited network memory resources without requiring any application or operating system code modifications, relinkling or recompilation. A preferred embodiment employs kernel-level driver software.

Abstract: A method is provided for producing crystalline nanoparticle semiconductor material. The method includes the steps of mixing a precursor in a solvent to form a reaction mixture and subjecting the reaction mixture to microwave dielectric heating at sufficient power to achieve a superheating temperature of the reaction mixture. A growth-phase reaction is permitted to proceed, wherein nanoparticles are formed in the heated reaction mixture. The reaction is then quenched to substantially terminate nanoparticle formation.

Abstract: A portable, lightweight, rugged, easy-to-operate biosensor useful for rapidly detecting cells, viruses, antibodies, and other proteins. A capillary tube has a capture antibody immobilized on its interior surface. The specific capture antibody is selected based upon a desired target analyte to be detected. A sample potentially containing the target antigen is introduced into the capillary tube. Thereafter, a second antibody labeled with a fluorescent dye is introduced. Upon excitation by electromagnetic energy, typically supplied by a laser, the fluorescence of the sample is captured and analyzed. The apparatus is extremely compact and rugged making it ideal for field use. In addition, accurate results may be obtained by relatively unskilled operators directly from a self-contained readout. Optionally, an external device (e.g., a computer) may be connected to the apparatus via an optional interface.

A mosaicking technique of the first and second image may be performed if the one salient pixel of the first image and the one salient pixel of the second image are registered successfully.
