Abstract: An anti-cavitation damping composite metal structure for a flow passage component and a preparation method thereof are provided. The preparation method includes: cladding a gradient functional material layer by layer on a substrate of a flow passage component; forming periodic structures on a surface of each layer of the gradient functional material through etching by an ultrafast laser to absorb a part of an impact load energy caused by cavitation of the flow passage component, where the layers of the gradient functional material form a gradient coating with a toughness increasing layer by layer and a hardness decreasing layer by layer from bottom to top; and forming nano twins on a surface layer by a laser shock peening technique, and implanting a residual compressive stress to further improve anti-cavitation resistance of a surface.

Abstract: The present disclosure provides a combined vaccine against human respiratory syncytial virus (RSV) infection and a method thereof for inducing immune response. The combined vaccine includes; a first composition including an immunologically effective dosage of a replication-deficient human adenovirus type 26 vector contains a nucleotide encoding an antigenic protein of RSV and a pharmaceutically acceptable vector; and a second composition including an immunologically effective dosage of a replication-deficient chimpanzee adenovirus type 63 vector contains a nucleotide encoding an antigenic protein of RSV and a pharmaceutically acceptable vector. The first composition is a primary immunization composition and the second composition is a booster immunization composition, or vice versa. In the present disclosure, the combined vaccine is used for inducing a protective immunity against RSV infection, and a method is provided for generating the protective immunity against RSV infection.

Abstract: Provided in the present application is a cathode material, a preparation method thereof and a lithium-ion battery, in which the cathode material includes a manganese-containing cathode active substance core, a fluorine-doped carbon coating layer, and a lithium ferrate shell layer, sequentially from inside to outside.

Abstract: Specifically disclosed in the present application is a lithium iron manganese phosphate cathode material, preparation method and application thereof. The lithium iron manganese phosphate cathode material includes a lithium iron manganese phosphate substrate and a coating layer on a surface of the lithium iron manganese phosphate substrate; the coating layer includes carbon quantum dots containing amino groups; and a mass ratio of manganese ions to carbon quantum dots containing amino groups is (4.5˜5.5):1 in the lithium iron manganese phosphate cathode material.

Abstract: An electrolyte including one or more nitrile benzoquinone compounds, and the nitrile benzoquinone compound is selected from the group consisting of the compounds represented by formula I, formula II, and formula III: The substituents R1 to R9 are each independently selected from the group consisting of hydrogen, a C2 to C12 ether group, a C1 to C12 alkoxy group, halogen, a C1 to C12 alkyl group, a C2 to C12 alkenyl group, a C2 to C12 alkynyl group, and a C6 to C26 aryl group. The electrolyte can form a stable protective film on a cathode, thereby increasing the cycle capacity retention rate and high temperature storage performance of an electrochemical device.

Abstract: Systems and methods for account reconciliation using a distributed ledger are disclosed. In one embodiment, a method for account reconciliation using a distributed ledger may include: (1) a payment sending financial institution receiving a transaction involving an account maintained by the payment sending financial institution for a payment receiving financial institution; (2) the payment sending financial institution communicating the transaction to the payment receiving financial institution using a transaction network; (3) the payment sending financial institution writing the transaction as a first ledger entry to the payment sending financial institution's copy of a distributed transaction ledger; (4) the payment sending financial institution receiving a second ledger entry from the payment receiving financial institution; and (5) the payment sending financial institution reconciling the account using the first ledger entry and the second ledger entry.

Abstract: A chiller-less cooling system for cooling an interventional detector comprising a detector housing. The detector housing comprising a detector tray to which the detector is attached, a lift frame on which a driving mechanism is installed to lift up/down the detector housing, a connecting arm to connect the detector tray and the lift frame, and a cover. The cooling system comprising a heat pipes connecting the detector tray and the lift frame so as to reduce a thermal resistance between the detector tray and the lift frame and transfer more heat from the detector, an external heat sink connected with the heat pipe for reducing a thermal resistance between the lift frame and an ambient environment, and a high heat transfer coefficient device embedded into the detector tray for collecting heat leading to the heat pipe, obtaining a uniform temperature distribution, and reducing a thermal resistance of the detector tray.
