Abstract: In a method for synchronizing acoustic asynchronous serial signals while drilling, communication and high-voltage signal isolation between a transmitting terminal and a receiving master control board are realized in an asynchronous serial communication way. The receiving master control board serving as a master control terminal configures parameters for the transmitting terminal in the asynchronous serial communication way and controls the excitation of a sound source. The transmitting terminal is a synchronous sound source excitation signal initiator; signal synchronization is realized under an asynchronous communication condition due to the coordination of the transmitting terminal and the receiving master control board; the transmitting terminal includes a plurality of transmitting boards, and asynchronous serial communication between each of the transmitting boards and the receiving master control board is realized through two data lines R+ and R.

Abstract: The present invention discloses a method for improving the blood compatibility of a material surface by using a controllable grafting technique. The method involves placing a monomer NVP, an RAFT reagent and a solvent acetonitrile in a container, adding an initiator AIBN, mixing the same uniformly, removing oxygen with liquid nitrogen, making the same react in an oil bath; after polymerization, adding liquid nitrogen to quench and stop the reaction, thus obtaining PVP-COOH; mixing the PVP-COOH with DCC and NHS; adding dry dichloromethane to the mixture in a nitrogen atmosphere, adding mercaptoethylamine, and making the same react in darkness at room temperature; obtaining a crude sample; dissolving the crude sample in water, and performing dialysis with deoxygenated water in darkness, and then obtaining HS-PVP by freeze-drying. An Au—S bond chemisorption method is used to controllably graft an anti-protein high-molecular polymer onto an Au surface.

Abstract: For image captioning such as for computer game images or other images, bottom-up attention is combined with top-down attention to provide a multi-level residual attention-based image captioning model. A residual attention mechanism is first applied in the Faster R-CNN network to learn better feature representations for each region by taking spatial information into consideration. In the image captioning network, taking the extracted regional features as input, a second residual attention network is implemented to fuse the regional features attentionally for subsequent caption generation.

The present structure can receive and charge the earphone via providing with the charging member, thereby users can use the cup with the multifunction cup lid to achieve the purpose of carrying one object with a variety of functions to further reduce the carrying burden and strengthen the convenience.

Abstract: In a production support system, process knowledge information is updated using machine learning on the basis of implementable process information, and implementable process information is output as a production plan of a product. Accordingly, production can be carried out considering factors, such as restart cost of facilities used in each of processes, for which skilled experience and knowledge are required with respect to the production of the product, and therefore the product can be produced effectively with low cost. Further, even when limitation conditions such as production capacity or quantity of a product exist for each of processes, suitable production can be carried out that satisfies these limitation conditions.

Abstract: A medical macromolecular microsphere adsorbent for a blood perfusion apparatus and a preparation method thereof are provided. The polystyrene-divinylbenzene microspheres are graded by different pore sizes and specific surface areas, medically purified, and grafted by a bioactivity-controlled grafting technology. In the microsphere adsorbent, the volume ratio of microspheres with pore sizes of 1-10 ?m, 10-100 ?m and 100 ?m is 1:(1-10):(1-20), the content of residual monomers in the microsphere has O.D190-400 nm?0.03. The microsphere adsorbent not only can adsorb harmful micromolecules in blood but also can effectively adsorb harmful medium-molecules and macromolecules in blood, thereby meeting clinical application demands.

Abstract: A near-bit constant-power wireless short-distance transmission apparatus includes a transmitting portion and a receiving portion. The transmitting portion is connected to a near-bit measurement sub while the receiving portion is connected to a measurement while drilling system. The transmitting portion processes data received by the bit measurement sub and then transmits it to the receiving portion. The receiving portion further processes the information and then transmits it to the measurement while drilling system. An insulating sub is inserted in the transmitting portion and separates the transmitting portion into a transmitting positive pole and a transmitting negative pole, which become electrically isolated from each other. Another insulating sub is inserted in the receiving portion and separates the receiving portion into a receiving positive pole and a receiving negative pole, which become electrically isolated from each other.

Abstract: Graft-versus-host disease (GVHD) is a lethal complication of allograft transplantation. The current strategy of using immunosuppressive agents to control GVHD may cause general immune suppression and limit the effectiveness of allograft transplantation. Adoptive transfer of regulatory T cells (Treg) can prevent GVHD in rodents, indicating the therapeutic potential of Treg for GVHD in humans. However, the clinical application of Treg-based therapy is hampered by the low frequency of human Treg and the lack of a reliable model to test their therapeutic effects in vivo. Human alloantigen-specific Treg are generated from antigenically-naïve precursors in a large scale ex vivo using allogeneic activated B cells as stimulators. Here, a human allogeneic GVHD model is established in humanized mice to mimic GVHD after allograft transplantation in humans.
