No more IPv4 address left with IANA or APNIC, IPv6 is critical to the Internet's continued growth. How can IPv6 be flexible and adaptive for a broad range of services? How can IPv6 network adapt to the services specified requirements with high quality of experiences to users? How can IPv6 network simplify management for services? How can IPv6 network(More)
The highly pathogenic avian influenza H5N1 virus still cause devastating effects to humans, agricultural poultry flocks, and wild birds. Wild birds are also detected to carry H5N1 over long distances and are able to introduce it into new areas during migration. In this article, our objective is to provide lists of bird species potentially involved in the(More)
BACKGROUND The highly pathogenic H5N1 avian influenza emerged in the year 1996 in Asia, and has spread to Europe and Africa recently. At present, effective monitoring and data analysis of H5N1 are not sufficient in Chinese mainland. METHODOLOGY/PRINCIPAL FINDINGS During the period from April of 2004 to August of 2007, we collected 14,472 wild bird samples(More)
Knowledge about the wetland use of migratory bird species during the annual life circle is very interesting to biologists, as it is critically important in many decision-making processes such as for conservation site construction and avian influenza control. The raw data of the habitat areas and the migration routes are usually in large scale and with high(More)
Advanced satellite tracking technologies provide biologists with long-term location sequence data to understand movement of wild birds then to find explicit correlation between dynamics of migratory birds and the spread of avian influenza. In this paper, we propose a hierarchical clustering algorithm based on a recursive grid partition and kernel density(More)
