Abstract: The invention discloses a method and system for guiding a packet data protocol activation. The method includes determining whether a packet data protocol is activated and if the determination result indicates that the packet data protocol is not activated because of including a wrong service access point name, analyzing service access point name information causing the packet data protocol not activated; introducing in an associating database for associating service access point name reason information causing the packet data protocol not activated and a guide information for properly setting the service access point name; inquiring the associating database based on the service access point name reason information obtained by the analyzing and obtaining the guide information for guiding a user to properly set the service access point name; and transmitting the guide information for guiding the user to properly set the service access point name to the user side.

Abstract: A “Scene Re-Lighter” provides various techniques for using an automatically reconstructed light transport matrix derived from a sparse sampling of images to provide various combinations of complex light transport effects in images, including caustics, complex occlusions, inter-reflections, subsurface scattering, etc. More specifically, the Scene Re-Lighter reconstructs the light transport matrix from a relatively small number of acquired images using a “Kernel Nyström” based technique adapted for low rank matrices constructed from sparsely sampled images. A “light transport kernel” is incorporated into the Nyström method to exploit nonlinear coherence in the light transport matrix. Further, an adaptive process is used to efficiently capture the sparsely sampled images from a scene. The Scene Re-Lighter is capable of achieving good reconstruction of the light transport matrix with only few hundred images to produce high quality relighting results.

Abstract: Provided is a kind of modified recombinant human endostatin that has the structure of CH3O—(CH2CH2O)m—CH2CH2CH2—N?H-Endostar, wherein the average molecular weight of CH3O—(CH2CH2O)m—CH2CH2CH2— is 20-40 kD. The modified recombinant human endostatin enhances the stability in vivo, improves blood drug concentration, prolongs half-life, markedly increases the activity of inhibiting the endothelial cells proliferation, thus reduces drug dosage and decreases administration frequency. Its application for preparing anti-tumor pharmaceutical compositions is also provided.
