These transcription factors play a crucial role in several key biological processes, including development. High-degree identity in the canonical forkhead domain has been used to divide Fox proteins into 23 families （FoxA to FoxS）. We surveyed the genome of three spiralians, the oyster Crassostrea gigas, the limpet Lottia gigantea, and the annelid Capitella teleta. We identified 25 C. gigas fox genes, 21 L. gigantea fox genes, and 25 C. teleta fox genes. The C. gigas fox and L. giganteafox genes represented 19 of the 23 families, whereas FoxI, QI, R, and S were missing. The majority of the Fox families were observed within the C. teletafox genes, with the exception of FoxR and S. In addition, thefoxAB-like gene,foxY-like gene, andfoxH gene were also present in the three genomes. The conserved FoxC-FoxL 1 cluster, observed in mammals, was also found in C. gigas. The diversity of temporal expression patterns observed across the developmental process implies the C. gigasfox genes exert a wide range of functions. Further functional studies are required to gain insight into the evolution of Fox genes in bilaterians.展开更多

However, for large-scale 3D video production, current systems are no longer adequate in terms of the time and labor required for conversion. In this paper, we introduce a distributed 2D-to-3D video conversion system that includes a 2D-to-3D video conversion module, architecture of the parallel computation on the cloud, and 3D video coding in the system. The system enables cooperation among multiple users in the simultaneous completion of their conversion tasks so that the conversion efficiency is greatly promoted. In the experiments, we evaluate the system based on criteria related to both time consumption and video coding performance.展开更多

Two approaches for the conversion of waste post consumer plastic into fuel have been investigated： （1） muffle furnace to reactor liquefaction system; （2） direct liquefaction system. Majority of used plastics are derived from ethylene, propylene, butadiene and benzene. Waste plastics are plastics that are used by the people in their daily life. It is collected from outside and city municipalities. Some of them are coded and rests are non-coded. A developed process discussed in this paper works with most of the waste plastic, both coded and non-coded. The plastics are heated up at 120-380 ℃ temperature to melt. The gaseous vapor is then condensed into liquid fuel.展开更多
