Abstract: The disclosure relates to a value transfer method, apparatus, and system, applied to the field of Internet technologies. The value transfer method includes: in response to receiving a value transfer request of a transaction initiator, generating an incomplete data set corresponding to each of transaction participants on each of transaction nodes, the incomplete data set including an encrypted account value of a corresponding transaction participant before and after a value transfer; merging incomplete data sets corresponding to the transaction participants to obtain a complete data set; requesting a third-party node to perform integrity verification on the complete data set, to obtain an account data set endorsed by a third party; and performing, based on a consensus reached on the account data set between blockchain nodes in a blockchain network, local ledger writing on the blockchain nodes according to the account data set on which the consensus is reached.

Abstract: A payment method by a processing server to process payment that is independently performed between a user equipment and a payment channel server is provided. The method includes: generating, by the processing server, a payment order bound to a merchant order generated by a merchant device by determining a corresponding item ID, of a service and/or a product for purchase, that is registered with the payment channel server, the merchant order corresponding to the service and/or the product provided by the merchant device; obtaining, by the processing server, a payment voucher corresponding to the payment order; matching, by the processing server, based on the payment voucher, the merchant order bound to the payment order; and transmitting, by the processing server to the merchant device, based on the matched merchant order, a service/product providing notification for providing the service and/or the product to the user equipment.

Abstract: A recommendation model training method includes: acquiring first preference information corresponding to users for a first object, the first object being an object on which the users have performed a designated operation; determining second preference information corresponding to users for a second object, the second object being an object on which the users have not performed a designated operation; correcting the first and second preference information based on preference features of users for an object and correlation features between objects and the users, to obtain third preference information of the users for the objects; generating training data based on the third preference information, a user attribute of a target user, an object attribute of a target object, and operation information of the target user for the target object; and performing iterative training on a target recommendation model based on the training data until a training condition is satisfied.

Abstract: A transaction processing method includes: dividing a to-be-processed transaction obtained from a database into at least two subtransactions; dividing each subtransaction into N parts with an association relationship; processing the N parts of each subtransaction based on the association relationship, to obtain a processing result of a lastly executed part of the N parts; determining, upon detecting an abnormal subtransaction based on the processing result, a processing policy matching an abnormality reason of the abnormal subtransaction; and processing the abnormal subtransaction by using the processing policy, to obtain a final processing result of the to-be-processed transaction.

Abstract: A water-cooling radiator structure with pump includes a pump having a water outlet and a water inlet; and a water-cooling radiator including a first chamber that has a water-receiving room and a plurality of mutually communicable water passages therein. The water-receiving room is filled with a working fluid that reaches a level. The first chamber is externally provided with an outlet and an inlet as well as a pump mounting recess for mounting the pump therein. The water outlet and the water inlet are located corresponding to the outlet and the inlet, respectively, to be communicable with the water-receiving room and located lower than or flush with the level of the working fluid in the water-receiving room. And, the pump is detachably integrated into the water-cooling radiator. With these arrangements, it is able to overcome the problem of failed operation of the pump when the water-cooling radiator is laid horizontally.

Abstract: A method, apparatus and system for processing a payment request for a virtual commodity on an open network platform are provided. The method includes: receiving a payment request that is sent by a third-party application server according to a request from a terminal, the payment request carrying at least an account identifier; deducting a charge from an account corresponding to the account identifier according to a payment attribute corresponding to the account identifier; and sending a charge deduction result corresponding to the account to the terminal via the third-party application server. According to the present method, usage rate of network and system resources is improved.

Abstract: This application discloses an information processing method performed at an application server. The application server receives a first virtual article identifier and a first account sent by a terminal in response to an operation of a user on a virtual article presentation interface. The server generates and stores a first order including the first virtual article identifier and the first account, obtains a current bill provided by a payment system and forwarded by the terminal, and a second account used to log into the terminal. The server determines a second order corresponding to the current bill, associates the current bill with the second order when a virtual article identifier and an account in the second order are the same as the second virtual article identifier and the second account; and sends a virtual article corresponding to the second virtual article identifier to the second account.

Abstract: A medication dispenser includes a base seat, a circuitry unit and an outer casing. The base seat includes a mouthpiece.
