With the severe acute respiratory syndrome epidemic of 2003 and renewed attention on avian influenza viral pandemics, new surveillance systems are needed for the earlier detection of emerging infectious diseases. We applied a "next-generation" parallel sequencing platform for viral detection in nasopharyngeal and fecal samples collected during seasonal(More)
BACKGROUND In April 2009, a novel swine-derived influenza A virus (H1N1pdm) emerged and rapidly spread around the world, including Japan. It has been suggested that the virus can bind to both 2,3- and 2,6-linked sialic acid receptors in infected mammals, in contrast to contemporary seasonal H1N1 viruses, which have a predilection for 2,6-linked sialic acid.(More)
Considering the characteristic of vector geo-spatial data for digital watermarking, this paper presents a new watermarking algorithm for vector geo-spatial data based on integer wavelet transform. By the proposed algorithm, the line and surface coordinate points are decomposed by integer wavelet transform firstly, then watermark is embedded in the low(More)
