A realistic 3D terrain was generated for part of the areas flooded due to 17th Street, New Orleans levee breaching during Hurricane Katrina by digital image processing techniques and GIS using LIDAR data in conjunction with high resolution multispectral satellite imagery. The DEM was used to generate mesh for simulating flood by CCHE2D Flood models. Propagation of the simulated flood was successfully visualized in realistic 3D environment by image draping technique using high resolution color orthophotographs. Obtained results indicate that (1) high resolution satellite imagery can be very useful to treat LIDAR data for realistic 3D terrain data generation, (2) ortho-rectified high resolution multispectral satellite data or color aerial photographs can be used in conjunction with the treated LIDAR data to generate true color realistic 3D terrain, and (3) propagation of simulated flood generated by CCHE2D Flood models can be visualized in realistic 3D environment using ArcGIS ArcScene software package.
Two types of Zn–Ln nanoscale complexes were constructed using Schiff base ligands, and the 12-metal Zn–Eu complex shows interesting luminescent sensing of metal cations.
Protein tyrosine kinase Tec, a kind of non-receptor tyrosine kinase, is primarily found to be expressed in T cells, B cells, hematopoietic cells, and liver cells as a cytoplasmic protein. Tec has been proved to be a critical modulator of T cell receptor signaling pathway. In the present study, a homolog of Tec was identified in the lamprey, Lampetra japonica. The full-length Tec cDNA of L. japonica (Lja-Tec) contains a 1923 bp open reading frame that encodes a 641-amino acid protein. The multi-alignment of the deduced amino acid sequence of Lja-Tec with typical vertebrate Tecs showed that it possesses all conserved domains of the Tec family proteins, indicating that an ortholog of Tec exists in the extant jawless vertebrate. In the phylogenetic tree that was reconstructed with 24 homologs of jawless and jawed vertebrates, the Tecs from lampreys and hagfish were clustered as a single clade. The genetic distance between the outgroup and agnathan Tecs' group is closer than that between outgroup and gnathostome Tecs' group, indicating that its origin was far earlier than any of the jawed vertebrates. The mRNA levels of Lja-Tec in lymphocyte-like cells and gills were detected by real-time quantitative polymerase chain reaction. Results showed that it was significantly upregulated under stimulation with mixed pathogens. This result was further confirmed by western blot analysis. All these results indicated that Lja-Tec plays an important role in immune response. Our data will provide a reference for the further study of lamprey Tec and its immunological function in jawless vertebrates.

Abstract Asian cultivated rice is believed to have been domesticated from a wild progenitor, Oryza rufipogon , offering promising sources of alleles for world rice improvement. Here we first present a high-quality chromosome-scale genome of the typical O. rufipogon . Comparative genomic analyses of O. sativa and its two wild progenitors, O. nivara and O. rufipogon , identified many dispensable genes functionally enriched in the reproductive process. We detected millions of genomic variants, of which large-effect mutations could affect agronomically relevant traits. We demonstrate how lineage-specific expansion of gene families may have contributed to the formation of reproduction isolation. We document thousands of genes with signatures of positive selection that are mainly involved in the reproduction and response to biotic- and abiotic stresses. We show that selection pressures may serve as forces to govern substantial genomic alterations that form the genetic basis of rapid evolution of mating and reproductive systems under diverse habitats.
