  • Publication number: 20120015344
    Abstract: The disclosure generally relates to a particulate composition formed from a conductive polymer bound to magnetic nanoparticles. The particulate composition can be formed into a biologically enhanced, electrically active magnetic (BEAM) nanoparticle composition by further including a binding pair member (e.g., an antibody or a fragment thereof that specifically recognizes a virus strain or a virus surface protein) bound to the conductive polymer of the particulate composition. The disclosure further provides compositions, kits, detection apparatus, and methods for detecting specific viral strains including those with pandemic potential. In the various embodiments, a triplex including the BEAM nanoparticle, a virus or virally derived material (e.g. strain- and/or strain subtype specific viral surface protein or fragments thereof), and a viral strain subtype-specific binding pair member (e.g., a glycan that recognizes a specific virus strain subtype) is formed and detected, such as by use of a biosensor.

  • Publication number: 20050220141
    Abstract: This invention relates to a method for protecting high layer service in the multi-layer communication equipment, include that low layer processing module which provides low layer transmission passages for high layer processing module, and high layer processing module which sets up transparent VP link passage from up and down node by the service of said module, in order to make the service processed by the said module avoid influence. Once detecting the fault of the said processing module, high layer processing module will message the low layer processing module, and the low layer processing module will set up bypass connection after detecting the fault of the high layer processing module, then isolate the failed high layer process module. According to the present invention, extra network passages are not necessary, the means of protecting network is not limited. The present invention aims to protect effectively ATM traffic when the processing ability of ATM layer invalidate between MSPP and MSTP.
