Wnt signaling affects cell-fate specification processes throughout embryonic development. Here we take advantage of the well-studied gene regulatory networks (GRNs) that control pregastrular sea urchin embryogenesis to reveal the gene regulatory functions of the entire Wnt-signaling system. Five wnt genes, three frizzled genes, two secreted frizzled-related(More)
Voltage source converter (VSC)-based high voltage direct current (VSC-HVDC) interconnectors can realize accurate and fast control of power transmission among AC networks, and provide emergency power support for AC networks. VSC-HVDC interconnectors bring exclusive fault characteristics to AC networks, thus influencing the performance of traditional(More)
E-commerce is essential for enterprises because it improves their understanding of customer needs and of the products and services available in the market [6,55,69]. Since 2011, an increasing number of traditional manufacturers have engaged in such initiatives. By conducting e-commerce, manufacturers can eliminate distributors and wholesalers; optimize(More)
The developing of the Application System always set the Business Process into the entire structure directly, each time the modification of the business process may make the program change largely. This structure adds the complexity to the system and hinders the flexibility of the system. Combining WWF and traditionally information system development theory(More)
