Abstract: A quinoline mercaptoacetate sulfonamide derivative, an intermediate, a pharmaceutical derivative or a formulation, and a preparation method and use therefor, wherein the structure of the quinoline mercaptoacetate sulfonamide derivative is as represented by the following formula (I). A preparation method for a compound containing a structure is also represented by the following formula. Experiments show that the compound has a good inhibitory effect on URAT1 transport uric acid in HEK293 transfected cells, and that the compound has good application prospects in the treatment of hyperuricemia or gout.

Abstract: A chip module has a plurality of first ports, at least some or all of the first ports are first selection ports, and each first selection port may act as a write port or a read port. The chip module further includes a first control module. The first control module controls, based on a transmit/receive requirement of the chip module, the first selection port to be switched to a read port or a write port, to match the transmit/receive requirement of the chip module. The first selection port may selectively act as a read port or a write port, so that switching can be performed based on an operating state of the chip module, increasing a read/write bandwidth. The first control module controls an operating state of the first selection port, to flexibly adjust a quantity of read ports and a quantity of write ports of the chip module.

Abstract: A chassis of a server comprises a backplane. The backplane is disposed in the chassis of the server, and the backplane includes a first sub-board, a second sub-board, and at least one air baffle. The first sub-board is isolated from the second sub-board. Each air baffle forms an included angle with the first sub-board and forms an included angle with the second sub-board. Space enclosed by the first sub-board, the second sub-board, and a side wall, an upper wall, and a lower wall of the chassis is divided into a first air cavity and at least one second air cavity by using the at least one air baffle. The first air cavity is used for at least one first module to dissipate heat, and the second air cavity is used for at least one second module to dissipate heat.

Abstract: A reciprocating power tool includes a reciprocating cutting mechanism arranged to be driven by a motor via a driving assembly. The driving assembly includes a resilient arrangement arranged to be charged when the cutting mechanism is driven by the motor. When the drive from the motor is terminated, the resilient arrangement is arranged to reverse the cutting mechanism from the direction of the drive from the motor.
