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)
Head of Line (HOL) blocking is one of the new challenges in the smart antenna system in wireless ad hoc networks. To address the problem, this paper proposes a novel Directional Network Allocation Vector-based Packets Scheduling (DBPS) algorithm. The algorithm gains greater throughput and is more suitable to the dynamic network topology than other methods.(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)
Gene expression in different spatial domains is often controlled by separate cis-regulatory modules (CRMs), but regulatory states determining CRM activity are not only distinct in space, they also change continuously during developmental time. Here, we systematically analyzed the regulatory sequences controlling hox11/13b expression and identified a single(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)
