RATIONALE Primary angiosarcoma of the spleen (PAS) is a very rare malignant neoplasm that originates from endothelial cells of the splenic blood vessels. Without typical clinical presentations and specific radiological features, PAS is very difficult to be early identified and 1-year mortality is extremely high. Late detection and spleen rupture are considered as the most important risk factors...

In remote sensing, image-based change detection techniques, analyze two images acquired over the same area at different times t1 and t2 to identify the changes occurred on the Earth's surface. Change detection approaches are mainly categorized as supervised and unsupervised. Generating the change index is a key step for change detection in multi-temporal remote sensing images. Unsupervised chan...

Community structure is vital to discover the important structures and potential property of complex networks. In recent years, the increasing quality of local community detection approaches has become a hot spot in the study of complex network due to the advantages of linear time complexity and applicable for large-scale networks. However, there are many shortcomings in these methods such as in...
