  • Publication number: 20190153489
    Abstract: The invention discloses a method for increasing the yield of L-arginine by knocking out flavin reductases, and belongs to the technical field of amino acid production by microbial fermentation. Genes frd1 and frd2 for encoding hypothetic NADPH-dependent FMN reductase in Corynebacterium crenatum SDNN403 are over-expressed in E. coli BL21 and are purified to form target proteins Frd181 and Frd188, and functions of the target proteins are identified to obtain a result showing that the proteins Frd181 and Frd188 both are NAD(P)H-dependent flavin reductases producing H2O2. By taking a genome of the Corynebacterium crenatum SDNN403 as a template, frd1 and frd2 gene deletion fragments are obtained by overlap extension PCR; connecting pK18mobsacB to obtain knockout plasmids pK18mobsacB-?frd1 and pK18mobsacB-?frd2; carrying out electric shock to transform the Corynebacterium crenatum SDNN403; and carrying out secondary screening to obtain recombinant strains 403?frd1 and 403?frd2.

  • Publication number: 20190122559
    Abstract: An autonomous driving system for a vehicle includes an autonomous lane change safety check method. An object relative to the vehicle and a current lane of travel is mapped and object data of the object is assessed. An object threat value for the object is assigned based on the object map and the object data. The object is grouped based the object threat value. An overall critical value is determined from the object threat value for the object and filtered to reduce signal noise. The critical value is compared to a predetermined criticality threshold, where the lane change safety check is failed when the critical value is over the threshold.

  • Patent number: 10088553
    Abstract: A method and sensor system are disclosed for automatically determining object sensor position and alignment on a host vehicle. A radar sensor detects objects surrounding the host vehicle in normal operation. Static objects are identified as those objects with ground speed approximately equal to zero. Vehicle dynamics sensors provide vehicle longitudinal and lateral velocity and yaw rate data. Measurement data for the static objects—including azimuth angle, range and range rate relative to the sensor—along with the vehicle dynamics data, are used in a recursive geometric calculation which converges on actual values of the radar sensor's two-dimensional position and azimuth alignment angle on the host vehicle.

  • Publication number: 20180148746
    Abstract: The present disclosure describes a genetically engineered a KASIII-independent fatty acid biosynthetic pathway that makes use of the promiscuous nature of the rest of the FAS enzymes (3-ketoacyl-ACP synthetase, 3-ketoacyl-ACP reductase, 3-hydroxyacyl ACP dehydrase, enoyl-ACP reductase) to bypass the KASIII step by providing a Co-A precursor of two or higher than two carbons (such as the four carbon butyryl-CoA) as the starting molecule. Since many CoA-based starter molecules can be supplied for the fatty acid synthesis, much more diversified products can be obtained with various carbon-chain lengths. As such, this disclosure will serve as a powerful and efficient platform to produce low to medium chain length products carrying many different functional groups.
