Abstract: The present disclosure relates to an item information push method. The item information push method includes: acquiring a plurality of attribute value sets of a to-be-promoted item according to preset value sets of a plurality of specified attributes; for the each attribute value set, determining an estimated warehouse-out quantity of the to-be-promoted item on a plurality of promotion platforms, according to historical traffic and historical warehouse-out quantities corresponding to a plurality of reference items and the historical traffic corresponding to the to-be-promoted item, on the plurality of promotion platforms; setting attribute values of the plurality of specified attributes of the to-be-promoted item according to the determined estimated warehouse-out quantity corresponding to the each attribute value set and the one set of values in the each attribute value set and sending the set attribute values to the plurality of promotion platforms.

Abstract: A method for designing a distributed communication topology of a micro-grid based on network mirroring and global propagation rates includes the following steps: first, determining the communication connectivity of distributed directed networks in the micro-grid; next, obtaining, for connected directed communication networks, mirror networks thereof based on a mirroring operation, and selecting an optimal distributed directed communication topology corresponding to a maximum performance indicator based on algebraic connectivity and communication costs; solving, for the optimized distributed communication topology, pinned distributed generation sets corresponding to different pinning numbers based on global propagation rates and out-degrees; and finally, establishing a distributed secondary voltage control of the micro-grid based on the optimal distributed communication network and pinned nodes of the micro-grid, to achieve accurate reactive power sharing and average voltage restoration.

Abstract: Embodiments of the present disclosure disclose an event execution method, device, and system. The method includes: obtaining first event result information obtained by executing a first event by a first application client logged in on a mobile terminal by using a first account, the first event result information indicating an account resource to be deducted; displaying the first event result information on a screen of a processing device; and requesting to execute a second event by using the processing device, the second event being used for deducting an amount of resource from a second account associated with the first account.

Abstract: A method and server for reallocating resources are provided. A resource reallocation instruction is received from a terminal corresponding to a user. The instruction carries first and second management platforms identifiers, a first amount of money for purchasing resources, and a first account identity registered by the user in the first management platform. A second account identity of the user in the second management platform is obtained, which corresponds to the second management platform identifier. The first amount of money is transferred from a resource management account to an account corresponding to the second account identity, and a request is made to the second management platform to allocate the resources to the account corresponding to the second account identity. A request is made to the first management platform to transfer the first amount of money from an account corresponding to the first account identity to the resource management account.

Abstract: A method for performing transactions is disclosed. The method is performed at a server device having one or more processors and memory for storing programs to be executed by the one or more processors. The method includes receiving, from a terminal device, a virtual resource transfer instruction associated with transferring virtual resource into a virtual account of a user. Virtual resource recorded in the virtual account corresponds to actual resource of the user used in a revenue-generation activity. The method also includes sending a resource transfer request to cause completion of an actual resource transfer in accordance with the virtual resource transfer instruction. The method further includes increasing an account balance of the virtual account in accordance with the virtual resource transfer instruction. The user can use the value of virtual resource transferred into the virtual account to perform commercial transactions from the terminal device.

Abstract: Method and device of processing a security transaction are disclosed. The method includes: receiving a transaction request from the mobile device, wherein the transaction request specifies a purchase transaction for a financial product; in accordance with a determination that the user does not have any existing account with the broker of the financial product, identifying a payment account of the user that has been bound with the user's account of the social networking platform; and based on user identity information and bank account information associated with the payment account, establishing a new account with the broker of the financial product on behalf of the user; and requesting the broker to execute the purchase transaction using the new account established by the server on behalf of the user.
