Abstract: The disclosure relates to a protein-type nanoparticle for multi-specific antibody delivery, a preparation method, and its application. The protein-type nanoparticle includes a polyester and a protein with a hydrophobic domain, and the hydrophobic domain of the protein is bound with the polyester through hydrophobic interactions. The protein is at least one of albumin, globulin and cell wall protein. The protein-type nanoparticle of the present disclosure has excellent stability and biocompatibility. The protein-type nanoparticle is used to prepare a multi-specific antibody delivery platform (?Fc-NP) by binding anti-IgG-Fc antibody or anti-IgG-Fc antibody fragment, which can stably, quickly and easily bind to multiple specific antibodies through antigen-antibody interaction and enhance the therapeutic effect of specific antibodies.

Abstract: Systems and methods directed to returning personalized image-based search results are described. In examples, a query including an image may be received, and a personalized item embedding may be generated based on the image and user profile information associated with a user. Further, a plurality of candidate images may be obtained based on the personalized item embedding. The candidate images may then be ranked according to a predicted level of user engagement for a user, and then diversified to ensure visual diversity among the ranked images. A portion of the diversified images may then be returned in response to an image-based search.

Abstract: The sense amplifier includes: an amplification module configured to amplify a voltage transmitted by a bit line or a reference bit line, when the sense amplifier is at an amplification stage; a first switch module configured to control the amplification module to be disconnected from the reference bit line, when the sense amplifier performs a read operation for the bit line and is at the amplification stage. In the disclosure, the power consumption of the sense amplifier may be reduced.

Abstract: A method, an apparatus and a system for conveniently measuring coronary artery vascular evaluation parameters are provided by the disclosure.

Abstract: “Optimal Cholesterol” utilizes edible nature plant extracted by a variety of technology, it is one of the nature plant medicines which can treat atherosclerotic coronary heart disease, cerebral vascular disease and systemic vascular disease in the world. Its function is to soften the arterial blood vessels, and to treat arteriosclerosis, protect and repair the vascular endothelial cells; soft plaque, fibrous plaque and calcified plaque are removed during the process of preventing plaque rupture, bleeding, erosion and ulcer; regulate micro-circulation, enhance the ability of coronary artery blood supply, adjust heart rate, furthermore, there's none toxic side effects after long-term use.
