Abstract: The present disclosure provides a method and apparatus for processing three dimensional graphic data, a device, a storage medium and a product, relating to a field of artificial intelligence, in particular to a field of autonomous driving. The specific implementation is: receiving a data compression request for a target graphic element in a three dimensional electronic map, and obtaining at least one vertex data corresponding to the target graphic element; extracting a global coordinate matrix with a shared attribute in the at least one vertex data; extracting local coordinate data with a private attribute respectively corresponding to the at least one vertex data; and sending, in response to a graphic drawing request for the target graphic element, the global coordinate matrix and the local coordinate data respectively corresponding to the at least one vertex data to a graphic display device.

Abstract: The present application provides use of a CCDC157 gene and mutant genes thereof as molecular markers in diagnosis of male infertility diseases. Experiments have shown that the CCDC157-MIF515 mutant gene/protein causes male infertility, spermatogenesis disorder, sperm dysfunction, reduced sperm count, reduced sperm motility, abnormal sperm morphology, abnormal sperm head, etc. The CCDC157-MIF515 mutant gene/protein of the present application can be used as target genes for diagnosing male infertility. Meanwhile, the expression level of the CCDC157 of CCDC157 gene/protein is significantly reduced in NOA patients and SCOS patients, and the male infertility can be prevented and/or treated by increasing the activity and/or expression of the CCDC157 protein.

Abstract: As disclosed herein, a desktop 3D display system is provided. A 2D image display module is used for receiving and displaying an integral imaging source. A viewing angle guide module is used for guiding light emitted from the integral imaging source. A light modulation module is arranged for modulating the light guided by the viewing angle guide module and reconstructing a 3D image. A rotation module is configured to enable synchronous rotation of the 2D image display module, the view angle guide module and the light modulation module, wherein. A rotation angle speed of the synchronous rotation is associated with the switching speed of the integral imaging source of the 2D image display module. For a 3D image reconstructed in a single visual area range, crosstalk created by the diffuse reflective feature of pixels on a 3D image in other visual areas can be eliminated, thereby improving the viewing experience.
