Abstract: An image encoding/decoding method and apparatus are provided, in which one of color component images forming an image is predicted from a different color component image using a correlation between the color component images. A first color component image selected from the color component images is encoded by intra prediction, and the other color component images are predicted using the reconstructed first color component image. Therefore, color distortion, which may occur when transforming an image color format to another color format, is prevented, thereby improving encoding efficiency.

Abstract: The present invention relates to a method of selecting high producer clones by using an expression vector, the expression vector comprising: (i) a gene expression cassette comprising a selectable marker gene to which polyA has been inoperably linked; and (ii) a gene expression cassette which encodes a recombinant protein of interest and to which polyA has been operably linked. According to the invention, high producer clones can be selected from cell populations at least 10 times fewer than in the existing methods of selecting cell lines. Particularly, high producer clones can be selected using a low concentration of MTX compared to a conventional stepwise gene amplification strategy which comprises carrying out multiple amplification steps while increasing the concentration of MTX.

Abstract: A display substrate includes a substrate, signal lines and test lines. The substrate includes a pixel region where pixels are disposed, a buffer region surrounding the pixel region and a grinding region surrounding the buffer region. The signal lines pass through the buffer region from the grinding region to provide the pixels with a driving signal. The test lines are disposed on the grinding region and the buffer region, respectively, so that the test lines intersect the signal lines in a lattice structure. Each of the test lines is electrically connected to the signal lines of a first number calculated by dividing a second number of the signal lines by a third number of the test lines. Thus, the performance of the pixels used for displaying an image may be tested more precisely.
