  • Patent number: 7651051
    Abstract: A vehicle with wings and a mechanism for causing a flapping motion in wings. Each wing structure comprises a wing and a wing spar coupled to a follower via a resilient member. Each wing carrier is pivotally connected to the body and is configured to restrain lateral movement and permit rotation of the wing spar about a feathering axis. A biasing member provides torsional bias to each wing spar. A linkage, driven by an actuator, transmits cyclic motion that rotates the wing carrier about a flapping axis, which moves the follower along a follower path. A guide attached to the vehicle body lies in the path of each follower, and the follower and guide are shaped such that each wing spar has a first rotational position about its axis along a first portion of the follower path and a second rotational position along a second portion of the follower path.

  • Publication number: 20090315910
    Abstract: Methods and systems for obtaining an alpha matte for an image are disclosed. First and second known portions of an image are determined. The alpha matte for the image is estimated based on an initial fuzzy connectedness (FC) determination between the entire image and the first and second known portions. A third known portion is obtained. The estimated alpha matte for the image is refined based on a subsequent FC determination between a subset of the image and the first, second, and third known portions for the subset of the image and the initial FC determination for a remainder of the image.

  • Patent number: 7631305
    Abstract: Methods and products for processing a software kernel of instructions are disclosed. The software kernel has stages representing a loop nest. The software kernel is processed by partitioning iterations of an outermost loop into groups with each group representing iterations of the outermost loop, running the software kernel and rotating a register file for each stage of the software kernel preceding an innermost loop to generate code to prepare for filling and executing instructions in software pipelines for a current group, running the software kernel for each stage of the software kernel in the innermost loop to generate code to fill the software pipelines for the current group with the register file being rotated after at least one run of the software kernel for the innermost loop, and repeatedly running the software kernel to unroll inner loops to generate code to further fill the software pipelines for the current group.

  • Patent number: 7619133
    Abstract: This invention relates to polynucleotide sequences encoding a gene that can confer resistance to the plant pathogen Colletotrichum, which causes anthracnose stalk rot, leaf blight and top dieback in corn and other cereals. It further relates to plants and seeds of plants carrying chimeric genes comprising said polynucleotide sequences, which enhance or confer resistance to the plant pathogen Colletotrichum, and processes of making said plants and seeds. The invention further presents sequences that can be used as molecular markers that in turn can be used to identify the region of interest in corn lines resulting from new crosses and to quickly and efficiently introgress the gene from corn lines carrying said gene into other corn lines that do not carry said gene, in order to make them resistant to Colletotrichum and resistant to stalk rot.

  • Patent number: 7615617
    Abstract: A novel approach is described for reversing aggregation and increasing refolding by application of hydrostatic pressure. A protein of interest in an aggregated, or inclusion body, or other non-native or inactive state is subjected to high hydrostatic pressure. This treatment denatures the protein to states (or conformations) competant for refolding and results in increased formation of native protein once pressure is released. The technique can facilitate conversion non-native proteins, including inclusion bodies and aggregates to native proteins without addition of chaotropic agents, changes in buffer, or large-scale dilution of reagents required for traditional refolding methods.

  • Publication number: 20090263362
    Abstract: The invention relates to a composition and method for enhancing fertilization. Fertilization enhancement is achieved by effectively delivering bioactive molecules with a lipid anchor (GPI-linked proteins) to the surface of epididymal or ejaculated sperm. The process may be facilitated or promoted in the presence of Clusterin/APOJ, a well-known lipid carrier. The rate of delivery, or removal, of bioactive molecules is regulated by the concentration of lipid carrier present. The acquisition of these molecules, such as Sperm Adhesion Molecule 1 (SPAM1) can significantly impact sperm maturation and function.

  • Publication number: 20090259451
    Abstract: A genome-scale metabolic network reconstruction for Clostridium acetobutylicum (ATCC 824) was created using a new semi-automated reverse engineering algorithm. This invention includes algorithms and software that can reconstruct genome-scale metabolic networks for cell-types available through the Kyoto Encyclopedia of Genes and Genomes. This method can also be used to complete partial metabolic networks and cell signaling networks where adequate starting information base is available. The software may use a semi-automated approach which uses a priori knowledge of the cell-type from the user. Upon completion, the program output is a genome-scale stoichiometric matrix capable of cell growth in silico. The invention also includes methods for developing flux constraints and reducing the number of possible solutions to an under-determined system by applying specific proton flux states and identifying numerically-determined sub-systems.
