  • Publication number: 20100156573
    Abstract: Complementary metamaterial elements provide an effective permittivity and/or permeability for surface structures and/or waveguide structures. The complementary metamaterial resonant elements may include Babinet complements of “split ring resonator” (SRR) and “electric LC” (ELC) metamaterial elements. In some approaches, the complementary metamaterial elements are embedded in the bounding surfaces of planar waveguides, e.g. to implement waveguide based gradient index lenses for beam steering/focusing devices, antenna array feed structures, etc.

  • Patent number: 7452693
    Abstract: Genetic and biochemical characterization of the leinamycin biosynthesis gene cluster from Streptomyces atroolivaceus S-140 revealed two PKS genes, lnmI and lnmJ, that encode six PKS modules, none of which contains a cognate AT domain. The AT activity is provided in trans by a discrete protein, LnmG, which loads the malonyl coenzyme A extender unit onto the ACP domains of all six PKS modules. This finding provides a basis for methods of engineering modular polyketide synthases and polyketide synthase/nonribosomal peptide synthetases.

  • Publication number: 20080044097
    Abstract: A system and method provide image data compression and reconstruction technique optimizations that may enhance (1) local gradient quantization, (2) quantized gradient merging, and/or (3) prediction and/or prediction error computations. A data structure may be created before image data compression that provides access to pre-computed quantization values during image data compression. Quantization merging may be performed by a one-to-one mapping of quantization vectors into corresponding quantization values. Subsequently, the sign of the quantization values may be checked to further reduce the number of logical steps required. A prediction technique may alleviate the effect that noise of neighboring pixels has on the current pixel. The optimizations may be applied to a JPEG-LS based algorithm to speed up processing by approximately 50%, while maintaining error controllability and compression ratio. The optimizations may enhance remote rendering and viewing of medical images in a client server environment.
