This study was conducted to examine whether the association ofa proliferation-inducing ligand (APRIL), spermatogenesis associated 8 (SPATA8), platelet-derived growth lhctor receptor-alpha (PDGFRA), and DNA polymerase beta (POLB) with SLE can be replicated in a Chinese Han population. Methods: Chinese SLE patients (n = 1247) and ethnically and geographically matched healthy controls (n 1440) were genotyped for the APRI L, SPATAS. PDGFRA, and POLB single-nucleotide polymorphisms (SN Ps), rs3803800 rs8023715, rs1364089 and rsl2678588 using the Sequenom MassARRAY System. Results: The Chinese Hart SLE patients and controls had statistically similar liequencies of alleles and genotypes of four gene polynlorphisms. Moreover, no association signal was detected on different genetic models (additive, dominant, and recessive, all, P〉 0.05) or in SLE subgroups stratified by various clinical nlanifestations (all, P 〉 0.05). Conclusions: Different genetic backgrounds from different ancestries and various populations may result in different genetic risk litctors for SLE. We did not detect any significant association with SNPs of APRIL SPATAS, PDGFRA, and POLB.展开更多

However, its creation procedure is still labor-intensive and far from maturity. Taking advantage of prevalence of digital cameras and the development of advanced computer vision technology, the paper proposes to reconstruct a building facade and recognize its surface materials from images taken from various points of view. These can serve as initial steps towards automatic generation of as-built BIM. Specifically, 3D point clouds are generated from multiple images using structure from motion method and then segmented into planar components, which are further recognized as different structural components through knowledge based reasoning. Windows are detected through a multilayered complementary strategy by combining detection results from every semantic layer. A novel machine learning based 3D material recognition strategy is presented. Binary classifiers are trained through support vector machines. Material type at a given 3D location is predicted by all its corresponding 2D feature points. Experimental results from three existing buildings validate the proposed system.展开更多
