Title: Low noise encoding and decoding method
Inventor: YU HAOPING
IPC: H04N7/01
Filed: 1997-12-23
Abstract: An adaptive digital image processor (22) precedes an MPEG2 encoder (24). The processor receives a high definition (1920 by 1080 pixels per image) video signal intended for broadcast or storage, and adaptively low-pass filters the signal. The signal is subjected to low-pass two-dimensional filtering (223) to eliminate encoding artifacts and related noise. The video signal is then horizontally down-sampled (226) to create a lower resolution hybrid signal (1280 by 1080 pixels per image). A receiver decodes and decompresses the hybrid signal. The hybrid signal is upsampled to its original resolution using existing hardware and software with a software modification.

Title: Human immunodeficiency virus entry inhibitor assay
Inventor: ZOU LINGLONG
IPC: G01N33/574
Filed: 2004-11-24
Abstract: The present invention is a method for evaluating the ability of a compound to prevent the Human Immunodeficiency Virus ("HIV") from entering into a T cell. The method involves fusing a first cell line that mimics HIV viral particles by expressing a gpl20-gp41 complex on the cell surface and that contains a Tat protein in the cytoplasm with a second cell line that mimics T cells by expressing CD4 and its co- receptors on the cell surface and that contains a Tat-inducible reporter gene expression cassette in the nucleus. The cell lines are fused alone or in the presence of a potential HIV entry inhibitor and the amount of beta-galactosidase produced by the fused cells is determined. Compounds that reduce the amount of beta-galactosidase produced by the fused cells have interfered with the interaction of the gpl20-gp41 complex and CD4 and its co-receptors and are therefore deemed be HIV entry inhibitors.
