    摘要: Systems and devices relating to a biconical antenna. The antenna has a top cone assembly and a bottom cone assembly, each cone assembly being coupled to a dielectric spacer at its apex. Each cone assembly has a cone section and a truncated cone section. The cone section is a cone with an apex which forms the apex of the cone assembly. The truncated cone section is coupled to the cone of the cone section at the cone's rim. The cone has an opening angle which is larger than the opening angle of the truncated cone. The biconical antenna can be fed by way of a coaxial cable with the outer cable feeding the bottom cone assembly and the inner cable feeding the top cone assembly.

    摘要: A method and apparatus for photon counting are disclosed. In an implementation, the present disclosure provides a dynamic-range photon-counting spectrometric sensor for low signal detection embedded in large parasitic background light signal. Rather than using a known forward illuminated imager approach of counting photons directly, embodiments of the present disclosure use a backward illuminated imager approach to generate a burst of electrons based on the photons, and perform photon detection by counting the generated burst of electrons using the plurality of CMOS chip pixels. An electronic circuit, in communication with the CMOS chip pixels, includes a fast clock enabling discrimination between electrons in time. The electronic circuit can be built on the face of a semiconductor wafer on which the CMOS chip pixels are provided.

    摘要: Methods and systems for presenting document search results to a user. A user enters search terms to be matched with indicators mentioned in documents from a specific corpus of documents. The search results, which are the documents with indicators or content that match the search terms, are provided to the user using a user interface. Each document in the search results are represented by a marker on a map in the user interface. Other indicators which appear with the searched for indicators in the documents are also mapped to the user interface. Documents with similar indicators in their content are clustered together in the map and the markers which represent them are color coded to differentiate them from markers belonging to other clusters.

    摘要: This invention discloses methods for identifying Francisella tularensis vaccine candidates. It enables identification of novel vaccine candidates and quality assurance for vaccine batches, assessment of protection in vaccinates and identification of the infecting agent in vaccinates. Mice were first vaccinated with Brucella abortus O-polysaccharide (OPS) vaccine. These animals were then given 10 LD50s of F. tularensis live vaccine strain (LVS). Sixty percent (60%) of the vaccinated mice survived the multiple lethal doses. Sera were collected from these surviving mice and the antibodies were used to probe supernatant and cell lysates of live F. tularensis LVS cultures. Several F. tularensis components were identified only by the noted “survivor” antisera. Of these identified proteins, enzyme digestions and chemical oxidation suggest post-translational modifications of some proteins e.g. a 52 kDa glycoprotein, a 45 kDa lipoprotein and a 19 kDa nucleoprotein. The 52 kDa component caused nitrous oxide induction in tissue cultures at low concentrations, cell death at high concentrations. Vaccination with this gave partial protection while addition of other components acted synergistically to give enhanced protection from 250 LD50s of F. tularensis LVS.
