  • Publication number: 20190311345
    Abstract: Systems and methods are provided for storing, sorting, and analyzing account transactions in a payment network, and for real-time data analytics. One embodiment of a real-time data storage and analytics system includes a payment network that collects and processes account transactions. The system also includes a first data cluster that includes a first data structure. The first data structure stores a set of the account transactions. Additionally, the system includes a second data cluster that in turn includes a second data structure. The second data structure stores account transactions for new account and account transactions for which there is insufficient space in the first data structure. Moreover, the system includes an application engine that generates a score for an account based on transaction data associated with the account transactions for the account.

  • Patent number: 10381443
    Abstract: A etch stop semiconductor rail is formed within a source semiconductor layer. A laterally alternating stack of dielectric rails and sacrificial semiconductor rails is formed over the source semiconductor layer and the etch stop semiconductor rail. After formation of a vertically alternating stack of insulating layers and spacer material layers, memory stack structures are formed through the vertically alternating stack and through interfaces between the sacrificial semiconductor rails and the dielectric rails. A backside trench is formed through the vertically alternating stack employing the etch stop semiconductor rail as an etch stop structure. Source strap rails providing lateral electrical contact to semiconductor channels of the memory stack structures are formed by replacement of sacrificial semiconductor rails with source strap rails.

  • Publication number: 20190168309
    Abstract: A large-scale multi-step synthesis method for ultralong silver nanowire with controllable diameter, comprises: an ethylene glycol solution containing polyvinylpyrrolidone and sodium chloride is fully heated to obtain a solution with strong reducibility, and then silver nitrate in glycol solution is added for a generation of a large number of crystal seeds; hydrogen peroxide is used to achieve the selection of the crystal seeds for a small amount of crystal seeds with particular sizes; the temperature is immediately raised to increase the reaction rate until the threshold of the etching crystal seeds of nitric acid is broke through; the temperature is lowered for long-timed reaction to slow down the reaction rate, reduce the probability of the isotropic seeds by self-nucleation and promote the absorption of small nucleus in the radial direction of large nucleus or nanowire, thus obtaining the ultralong silver nanowire.
