Abstract: Provided are a transmission method, apparatus and system and a computer-readable storage medium. The transmission method includes creating an automatic repeat request process for a first packet; setting a lifetime for the automatic repeat request process; and sending the first packet. The lifetime is set for the automatic repeat request process so that the automatic repeat request process can be removed in time. In this manner, in the case where a limited number of automatic repeat request processes are simultaneously supported, a new automatic repeat request process can be created for a newly transmitted packet in time, and thus the transmission efficiency is improved.

Abstract: This application relates to the field of power supply packaging technologies, and in particular, to a PCB-pinout based packaged module, including a packaged module and a pin exposed outside the packaged module. The packaged module includes a PCB and a power component. The PCB has a first surface and a second surface that are disposed opposite to each other, and the power component is disposed on the first surface or the second surface of the PCB. The power component performs communication connection with a pin located on one side of the first surface or one side of the second surface of the PCB through surface-layer copper of the PCB. The pin located on one side of the first surface or one side of the second surface of the PCB is a surface-layer copper etching pattern that is located on the PCB and that is exposed outside the packaged module.

Abstract: Beta-lactam compounds to detect carbapenemases or microbial carbapenem resistance are disclosed. The compounds contain a chemical probe.

Detection of the released chemical probe indicates the presence of carbapenemases and the presence of microbial carbapenem resistance.

Abstract: Some embodiments provide a system to facilitate transaction processing associated with an industrial asset supply chain having a first entity and a second entity. A first entity computer processor may retrieve, from a first entity database, information associated with pre-delivery data about the industrial asset. The first entity computer processor may then record pre-delivery data about the industrial asset via a secure, distributed transaction ledger. A second entity computer processor may retrieve, from a second entity database, information associated with a post-delivery event involving the industrial asset. The second entity computer processor may then record post-delivery event data about the industrial asset via a secure, distributed transaction ledger. The post-delivery event data might indicate, for example, that the industrial asset has been delivered, has been installed, is working properly, has been used, etc.

Abstract: An information processing method is provided for a first terminal. The method includes displaying, by the first terminal, first information and an interactive prompt corresponding to the first information; and detecting, by the first terminal, an interactive operation formed based on the interactive prompt to generate operation information of the interactive operation. The method also includes sending, by the first terminal, the generated operation information to a server; receiving response information sent by the server; displaying, by the first terminal, an interaction status based on the response information; receiving, by the first terminal, colleting-information for collecting at least one to-be-issued benefit sent by the server; and displaying, by the first terminal, the collecting-information. The collecting-information is sent when the server detects that the interaction status meets a preset interaction-completion condition.

Abstract: According to some embodiments, a system may facilitate collaborative transaction processing associated with a supply chain having a first entity and a second entity. In particular, a first entity database may store electronic records including information associated with at least a portion of the supply chain, and a first entity communication port may exchange information via a distributed computer system. A first entity computer processor may retrieve from the first entity database the information associated with the at least a portion of the supply chain. A subset of information about the supply chain may be identified by the first entity computer processor as being of interest to the second entity. The identified subset of information about the supply chain may then be recorded via a secure, distributed transaction ledger.
