Abstract: The present disclosure discloses a preparation method of a powder metallurgy (PM) superalloy with high strength and plasticity. Under the multi-field coupling action of a thermal field and a force field, the PM superalloy is obtained in a high-temperature graphite mold by using the method of conducting heat preservation and oscillating-pressure sintering in two steps. Under the action of a circulating pressure, rearrangement of powders and discharge of pores are promoted, and therefore, the PM superalloy is sintered and formed. The present disclosure further discloses a PM superalloy prepared by using the method above. The PM superalloy has the characteristics of low grade of prior particle boundary defects, uniform grain refinement and high density. The sintered PM superalloy obtained in the present disclosure has a yield strength of 955 MPa, a tensile strength of 1,437 MPa and an elongation of 31.9%, and has high strength and plasticity.

Abstract: A two-stage medical image registration method based on progressive images (PIs) to solve the technical problem of low registration accuracy of traditional image registration methods includes: merging a reference image with a floating image to generate multiple intermediate PIs; registering, by a speeded-up robust features (SURF) algorithm and an affine transformation, the floating image with the intermediate PIs to acquire coarse registration results; registering, by the SURF algorithm and the affine transformation, the reference image with the coarse registration results to acquire fine registration results; and comparing the fine registration results of the intermediate PIs, which are acquired by iteration, and selecting an optimal registration result as a final registration image. The method can achieve multimodal registration for brain imaging with MI, NCC, MSD, and NMI superior to those of the existing registration algorithms. The method effectively improves the registration accuracy through the progressive medical image registration strategy.

Abstract: Provided is an anti-atopic dermatitis protein. A corresponding pharmaceutical composition contains a pharmaceutically acceptable carrier and the anti-atopic dermatitis protein. The anti-atopic dermatitis protein is one or more proteins selected from the group consisting of Helicobacter pylori-neutrophil-activating protein (HP-NAP) and recombinant maltose-binding protein fused to neutrophil-activating protein (rMBP-NAP). HP-NAP and rMBP-NAP can effectively treat AD in an oxazolone-induced AD model, providing brand-new drugs for the treatment of AD.

Abstract: The disclosure provides a nanolaser based on a depth-subwavelength graphene-dielectric hyperbolic dispersive cavity, comprising a pumping light source and the depth-subwavelength graphene-dielectric hyperbolic dispersive cavity; wherein the depth-subwavelength graphene-dielectric hyperbolic dispersive cavity is a spherical or hemispherical hyperbolic dispersive microcavity formed by alternately wrapping a dielectric core with graphene layers and dielectric layers. Because the graphene plasmon has unique excellent performances, such as an electrical adjustability, a low intrinsic loss, a high optical field localization, and a continuously adjustable resonance frequency from mid-infrared to terahertz, compared with a common metal-dielectric hyperbolic dispersive characteristic, a graphene-dielectric hyperbolic dispersive metamaterial used by the disclosure not only may highly localize an energy of an electromagnetic wave in a more depth-subwavelength cavity, but also may reduce an ohmic loss and improve a quality factor.
