Natural and experimental infections of Japanese tree sparrows with Japanese encephalitis virus

, : Natural and experimental infections of Japanese tree sparrows with Japanese encephalitis virus. Archives of Virology 49(4): 373-376

Of wild Japanese tree sparrows [Passer montanus saturatus], 20-37% had neutralizing antibodies to Japanese encephalitis virus (JEV). Sparrows free of antibodies were inoculated with 10,000 plaque-forming units of JEV. None of the birds became clinically ill. Virus could be detected in blood plasma during the 1st 3 days after inoculation but not thereafter. Neutralizing antibodies started to appear at 4 days after inoculation, and the response was of variable duration, in some cases extending up to 200 days after inoculation. The significance of wild birds in the winter survival of JEV is discussed.

In this paper, we develop a decomposition model to restore blurred images with missing pixels. Our assumption is that the underlying image is the superposition of cartoon and texture components. We use the total variation norm and its dual norm to...

In the last decade, field studies in the northern Arabian Sea showed a drastic shift from diatom-dominated phytoplankton blooms to thick and widespread blooms of the green dinoflagellate, Noctiluca scintillans. Unlike the exclusively heterotrophic...
