Abstract: Disclosed in the present application are a concrete protection material, and a preparation method and a construction method therefor. The concrete protection material consists of 50%-90% of a component A and 10%-50% of a component B in percentage by weight, where the component A is prepared from 30%-65% of organic silicon, 2%-5% of nano-silicon dioxide and the balance of an organic solvent in percentage by weight; and the component B is prepared from 20%-50% of an organic base and the balance of water in percentage by weight. The present application not only can form nano-particles having a strengthening effect in capillary channels of a concrete surface layer, but also can achieve a technical effect of superhydrophobicity on the concrete surface layer.

Abstract: A method and apparatus for setting memory, and an electronic device and a storage medium. The method comprises: obtaining a memory application instruction generated by a process corresponding to a simulator; determining target number of times of mappings for a first virtual memory space according to the memory application instruction; determining remaining number of times of mappings of the first virtual memory space; determining whether the remaining number of times of mappings is zero; if not, mapping the first virtual memory space to a second virtual memory space by using a copy-on-write instruction, updating the remaining number of times of mappings, and returning to the step of determining whether the remaining number of times of mappings is zero; and if yes, stopping mapping the first virtual memory space to the second virtual memory space by using the copy-on-write instruction.

Abstract: In some examples, a method includes identifying a first listing and an additional listing having one or more characteristics in common, the first listing and the additional listing published on an online marketplace; receiving a request to perform an operation on the first listing and the additional listing; in response to the request, generating a batch of events based on the operation, the batch of events including a first event to be performed on the first listing and a second event to be performed on the additional listing; performing the first event on the first listing and the second event on the additional listing.

Abstract: A method and system for identifying and labeling fraudulent store return activities includes receiving, by a server, retailer events from an online transaction system of a retailer, the retailer events comprising records of transactions between customers and the retailer, including sale, exchange and return activities across multiple stores. The retailer events are processed to build a network that associates stores, transactions, payment instruments, and customer identification over related activity sequences of transactions.

Abstract: Systems, methods, and devices for polyglot computing may include, in a single execution, adapting at least one first instruction in a first language and at least one second instruction in the first language into a code comprising the at least one first instruction in the first language and the at least one second instruction in a second language; producing a first result in the first language based on executing the code using a dataset in a data store, wherein the producing the first result in the first language is performed in the single execution; producing a second result in the second language based on executing the code using the dataset; and adapting the second result in the second language into the second result in the first language.

Abstract: In one example, a system comprises one or more processors to execute a business event processing module. The business event processing module is configured to receive a request to perform an operation on a listing published by an online marketplace, identify at least one additional listing having certain characteristics in common with the listing from a plurality of published listings including the listing, and automatically perform the operation on the at least one additional listing. The system includes a last event processor to determine a performance of the operation on a last instance of the at least one additional listing.
