end-to-end vector
1.Simulations show that, compared with AODV (ad hoc on-demand distance vector) and DSR (dynamic source routing), this protocol saves the overhead of the protocol and reduces the end-to-end delay of the packet.
3.To this end, the expression vector of Cre-ERt under the control of the mouse albumin gene promoter/enhancer, alb-Cre-ERt, was constructed, and transfected into engineering BRL (Rat hepatocytes) and BRK (Rat kidney) reporter cells which carries a chromosomally integrated ‘floxed’ βgeo gene, which is inserted between the promoter and the human alkaline phosphatase( hAP) reporter gene, thereby preventing hAP reporter gene transcription, respectively.
4.To improve the targeting of adenovirus vector for gene therapy,a fusion gene sCAR-EGF,in which epidermal growth factor gene was fused to the 3′ end of extracellular Coxsackie virus-adenovirus receptor gene,was constructed and cloned into shuttle plasmid pDC315 to obtain a recombinant plasmid pDC315-sCAR-EGF.
5.The plant expression vector pBI121. 2 was digested with BamH I and Sma I , the bovine casein B gene cDNA code fragment was seperated from pBα slC184 plasmid with Bgl Ⅱ and EcoR I, the cloning process includes two steps: the first, the Bgl Ⅱ sticky end of casein B gene was ligased to BamH Ⅲ sticky end of pBI 121. 2;
9.This paper derives the effective synthetic aperture length equation expressed as the initial position, the velocity and the synthetic aperture time when the radar operates in spotlight mode and the vehicle does uniform straight line motion, gives the ideal azimuth resolution equation expressed as the radar wavelength, the angles between velocity vector and line of sight from the antenna phase center to target at the begining and end time of synthetic aperture.
