Abstract: A bi-directional penetrating metal bottleneck structure of a type IV hydrogen storage tank is provided, which includes a metal valve seat, a plastic liner, and a fiber winding layer. A valve seat hole is formed on an inner side of the metal valve seat, and the metal valve seat includes an annular flange, a valve seat column section, and a valve seat extension. L-shaped through holes and radial penetrating holes are formed in the valve seat column section. The valve seat hole is an irregular through hole and is provided with an annular groove. The valve seat extension is provided with a winding inclined plane, a self-tightening conical surface, a circumferential groove, and axial penetrating holes. The plastic liner includes an inner plastic joint, an outer plastic joint, a tapered connecting section, L-shaped connectors, radial connectors, axial connectors, and a reinforcement section.

Abstract: A computing device is provided, including a plurality of memory devices, a plurality of direct memory access (DMA) controllers, and an on-chip interconnect. The on-chip interconnect may be configured to implement control logic to convey a read request from a primary DMA controller of the plurality of DMA controllers to a source memory device of the plurality of memory devices. The on-chip interconnect may be further configured to implement the control logic to convey a read response from the source memory device to the primary DMA controller and one or more secondary DMA controllers of the plurality of DMA controllers.

Abstract: Disclosed are a polyethylene glycol conjugate drug, and a preparation method therefor and the use thereof. Specifically, the present invention relates to a polyethylene glycol conjugate drug represented by formula A or a pharmaceutically acceptable salt thereof, a method for preparing the polyethylene glycol conjugate drug or the pharmaceutically acceptable salt thereof, an intermediate for preparing the polyethylene glycol conjugate drug or the pharmaceutically acceptable salt thereof, a pharmaceutical composition comprising the polyethylene glycol conjugate drug or the pharmaceutically acceptable salt thereof, and the use of the polyethylene glycol conjugate drug or the pharmaceutically acceptable salt thereof in the preparation of a drug.

Abstract: In some examples, a semiconductor package comprises an electrically conductive surface and a bond wire coupled to the electrically conductive surface. The bond wire includes a first stitch bond coupled to the electrically conductive surface, and a second stitch bond contiguous with the first stitch bond and coupled to the electrically conductive surface. The second stitch bond is partially, but not completely, overlapping with the first stitch bond.

Abstract: Disclosed are methods for preparing a high-performance soft magnetic composites and magnetic toroidal cores thereof. A spherical soft magnetic alloy particle is coated with an insulating layer to form a mixed powder, and the mixed powder is loaded into a mold and subjected to a compression molding. An external magnetic field is applied during the compression molding of the mixed powder, and the external magnetic field is parallel to a working magnetic circuit plane and perpendicular to a normal direction of the working magnetic circuit plane. Then a stress-relief annealing is performed to obtain the high-performance soft magnetic composite.

Abstract: The present invention addresses the problem of providing a method and a reagent for measuring the uptake capacity of a lipoprotein with higher accuracy. This problem is solved by preparing a lipoprotein incorporating a labeled sterol, by mixing the lipoprotein in a sample and the labeled sterol in the presence of a surfactant having no cyclic structure, and measuring the uptake capacity of the labeled sterol of the lipoprotein.

Abstract: Provided is a monoclonal antibody or antigen-binding fragment thereof which binds to a peptide consisting of 51st to 110th amino acid sequence or a peptide consisting of 201st to 267th amino acid sequence of an amino acid sequence of SEQ ID NO: 1, and is capable of binding to high-density lipoproteins of (1) to (3) below; (1) high-density lipoprotein that is oxidatively modified, (2) high-density lipoprotein that is not oxidatively modified, and (3) high-density lipoprotein incorporating labeled cholesterol.
