Infection by different strains of influenza virus presents different pictures. Whether the pathogenicity of influenza virus is defined by the ability of the virus to induce differential immunopathlogical responses in the lungs still remains unclear. We compared the immunopathological response induced by influenza virus A/WSN/33 (H1N1) and that by A/Panama-like (H3N2) virus in C57BL/6 mice. WSN virus,...
This study proposes a novel WDM EPON system based upon an AWG, in which multiple wavelengths are established in both the upstream and the downstream fibers. The use of the AWG enables the WDM EPON architecture to achieve wavelength spatial-reuse and to provide an intercommunication capability between ONUs. As a result, the architecture not only allows upstream access to the central office but also...
This study proposes a novel WDM EPON system based upon an AWG, in which multiple wavelengths are established in both the upstream and the downstream fibers. The use of the AWG device enables the WDM EPON architecture to support wavelength spatial reuse and allows the ONUs to communicate directly with one another rather than through the OLT. The proposed WDM EPON scheme takes account of the requirement...
