  • Publication number: 20150313980
    Abstract: Disclosed herein are mutant Plasmodium-species parasites that are genetically attenuated (GAP). They retain the ability to infect a host and invade host hepatocytes but subsequently their development is completely arrested within the liver stage of Plasmodium development and the parasites do not reach the blood stage of development. Vaccines and pharmaceutical compositions comprising genetically attenuated Plasmodium sporozoites as well as methods of using the same are likewise provided.

  • Patent number: 9119857
    Abstract: HslVU is the proteasome-related system composed of HslV peptidase and HslU chaperone. It is involved in intracellular proteolysis. The presence of HslVU homologs in pathogenic microbes and its absence in human makes it an antimicrobial drug target. The functional HslVU complex forms when HslV dodecamer is flanked at both ends by HslU hexamers. In the HslVU complex, intercalation of C-termini residues of HslU subunits into the clefts between adjacent HslV subunits results in allosteric activation of HslV. We identified small molecules capable of activating HslV peptidase in the absence of its natural activator HslU. Quinazoline and chromone derivatives were suggested by ligand docking to bind at the HslU C-termini intercalation pockets in the HslV. This was confirmed by HslV activation assays with these compounds that gave ED50 in sub-micromolar range. The results showed that small, extracellular non-peptidic molecules can activate the HslV peptidase which in turn would initiate intracellular proteolysis.

  • Patent number: 9011177
    Abstract: A cable bypass assembly is disclosed for use in providing a high speed transmission line for connecting a board mounted connector of an electronic device to a chip on the device board. The bypass cable assembly has a structure that permits it, where it is terminated to the board mounted connector and the chip member, or closely proximate thereto to replicate closely the geometry of the cable. The connector terminals are arranged in alignment with the cable signal conductors and shield extensions are provided so that shielding can be provided up to and over the termination between the cable signal conductors and the board connector terminal tails. Likewise, a similar termination structure is provided at the opposite end of the cable where a pair of terminals are supported by a second connector body and enclosed in a shield collar. The shield collar has an extension that engages the second end of the cable.

  • Publication number: 20150025913
    Abstract: At least one attribute type associated with an individual in a first record of a first database and one or more similar attribute types in record(s) of other second database(s) are located. The attribute types compared. Based on the comparison, a first weighted score for the first record and another weighted score for each other records are computed. The weighted score indicates a likelihood the particular attribute type is associated with a same individual as other attribute type(s) located in other record(s) and further accounts for a time delta between measurements of the attribute types. Confidence score outputs for the records are also computed. The confidence score output of a record is based on all weighted scores of that record and indicates a likelihood that record is associated with the same individual. At least one database is updated based on at least one of the confidence score outputs.

  • Publication number: 20140281248
    Abstract: A system and method to enforce read-write partitioning in an N-way, set associative cache may limit a number of ways allocated for storing modified data in a set to a value W and limit a number of ways holding read data to a value R. The cache may be configured where N=R+W. Furthermore, a number of ways storing prefetched read data may be limited to RP, while a number of ways storing prefetched modified data may be limited to WP. The values for W, R, WP, and/or RP may be determined using a prediction method to estimate cache miss rates for different values for W, R, WP, and/or RP and selecting values corresponding to a desired cache miss rate, and so allowing for selective application of the read-write partitioning.
