  • Patent number: 10081705
    Abstract: The invention provides a class of wedge-type block copolymers having a plurality of chemically different blocks, at least a portion of which incorporates a wedge group-containing block providing useful properties. For example, use of one or more wedge group-containing blocks in some block copolymers of the invention significantly inhibits chain entanglement and, thus, the present block copolymers materials provide a class of polymer materials capable of efficient molecular self-assembly to generate a range of structures, such as periodic nanostructures and microstructures. Materials of the present invention include copolymers having one or more wedge group-containing blocks, and optionally for some applications copolymers also incorporating one or more polymer side group-containing blocks. The present invention also provides useful methods of making and using wedge-type block copolymers.

  • Patent number: 10074196
    Abstract: A method for reconstructing a three-dimensional image dataset from two-dimensional projection images includes recording the projection images using a collimator downstream of an X-ray source. A local Laplace filter is initially applied to the projection data of the projection images during the reconstruction using filtered back-projection. After this, high-frequency spikes arising in the Laplace-filtered projection data at boundaries to the image region are removed by a spike filter, and a global residual filter is applied. A fit parameter describing a fit function approximating the projection data characteristic in the uncorrected projection images inside the image region is determined based on at least marginal values of the projection data present at the boundaries. Next, following on from the use of the residual filter, an additive correction of the residual-filtered projection data in the image region is performed with the fit function scaled by a scaling factor.

  • Patent number: 10027641
    Abstract: The present disclosure discloses a method and an apparatus of account login to solve the problem of low efficiency of account login in existing technologies. A client of the method captures an image of a first credential of a user, recognizes user information of the user that is included in the captured image, includes the recognized user information into a login request, and sends the login request to a server for logging into an account that corresponds to the user information. Through this method, a user does not need to input his/her username when using a client for account login, but perform the account login by directly capturing an image of a first credential using an image capturing device of the client, thus effectively improving the efficiency of account login.
