Abstract: Disclosed is a lumped center conductor assembly comprising a center conductor main body. A gyromagnetic sheet is provided on the center conductor main body; the center conductor main body and the gyromagnetic sheet are both a polygonal structure symmetrical along a central axis thereof; and there are three conductor legs in an annular array on sides of the center conductor main body. According to the present invention, the three conductor legs are bent twice to naturally form required included angles, without the need of using a complex and high-cost tooling fixture for correction. According to the present invention, the three conductor legs are vertically bent upwards and are in close contact with side walls of the gyromagnetic sheet, thereby solving the problem of insufficient contact between the conductor legs and the side surface of the gyromagnetic sheet.

Abstract: An isolator includes a casing. An interior of the casing includes a positioning ring, a lower permanent magnet, a lower uniform magnetic sheet, a lower ferrite, a central conductor, an upper ferrite, a six-foot uniform magnetic sheet, an upper permanent magnet, a temperature compensation sheet and an upper uniform magnetic sheet in sequence from bottom to top. A cover plate is connected to the top of the casing. The central conductor comprises three central junctions forming an angle of 120 degrees with each other, and each having a longitudinal slit along a center line thereof, and first and second transverse slits respectively intersecting with the longitudinal slit, the second transverse slit being located outside of the first transverse slit. A method is disclosed for implementing the isolator, which increases internal magnetic field intensity, reduces third-order inter-modulation, and improves signal quality.

Abstract: Provided are a supported catalyst, a preparation method therefor and use thereof, and a method for the preparation of isobutylene from halomethane. The catalyst is characterized in that it comprises a carrier and a metallic active component supported on the carrier, wherein the metallic active component comprises zinc oxide and zinc halide. On the basis of the total amount of the catalyst, by weight content, the content of zinc oxide is 0.5%-20%, the content of zinc halide is 10%-50%, and the content of the support is 40%-88%. Compared with the prior art, the catalyst of the present invention can convert halomethane into isobutylene with a high selectivity.

Abstract: System and methods for generating recommendations based on a determined skill gap are disclosed. A social networking system determines an employment role associated with a particular job listing, wherein the particular job listing has an associated source organization. The social networking system identifies one or more similar members associated with the source organization and having an employment role similar to the determined employment role. The social networking system generates a composite list of skills associated with the one or more similar members. The social networking system compares the skills included in the composite list of skills with a list of skills associated with the particular job listing to determine a list of missing skills.

Abstract: A system and method for determining similar members in an organization is disclosed. In some example embodiments, the social networking system receives a request for a particular job listing from a client system associated with a first member of a social networking system. The social networking system determines a first employment role for a job associated with the particular job listing. The social networking system identifies a source organization for the particular job listing. The social networking system identifies one or more similar members, wherein each identified similar member is associated with the source organization and has an employment role similar to the first employment role. The social networking system communicates the particular job listing and the identified one or more similar members to the client system for display.

Abstract: The present invention provides a series of cyclin-dependent protein kinases (Cdks) inhibitors, Scutellaria flavonoid organic amine derivatives, synthesis and use thereof. The preparation method is as follows: taking Baicalein (or Wogonin) from Scutellaria baicalensis as lead compound, mixting it with formaldehyde solution and organic amine compounds based on the molar ratio of 1:1-1.2:1-1.2, adding methanol of duplicate weight than baicalein and reacting at 50-70° C., filtering the sediment and washing and then drying so as to get the product with a content of not less than 97% (weight). Similar to Flavopiridol and P276-00, the activity of baicalein organic amine derivatives inhibiting Cdks has an increase of 50 times compared with that of Baicalin. It can selectively induce apoptosis of the proliferative phase cancer cells, which has scarcely any influence to the normal structure, and it belongs to anticancer drugs of cell cycle inhibitor kind.
