Abstract: A circuit board assembly is applied to the field of electronic communications technologies to resolve a prior-art heat dissipation problem of a circuit board. The circuit board assembly combines, on a second circuit board, low-speed signals transmitted between a plurality of I/O modules and an IC chip, and then transmits the combined low-speed signals to the IC chip by using a low-speed cable. A low-speed signal sent by the IC chip to the plurality of I/O modules is extended to a plurality of low-speed signals on the second circuit board, and then the plurality of low-speed signals are separately sent to the plurality of I/O modules. This may be applied to a scenario in which a relatively large quantity of electronic components need to be disposed on a circuit board.

Abstract: An information exchange method based on a virtual space scene is performed at a computing device, the method including: obtaining location information of a current terminal; obtaining, according to the location information of the current terminal, map data of a range in which the current terminal is located; drawing, according to the map data, a map in a constructed three-dimensional space, to obtain a drawing result; simulating, according to the drawing result, a real environment of a geographical location of the current terminal in the three-dimensional space, to obtain a virtual space for information exchange; and collecting an operation triggered by at least two terminals in the virtual space, and controlling information exchange processing of the at least two terminals according to a generated operation instruction.

Abstract: The present invention relates to an azetidine derivative for use as a Janus kinase (JAK) inhibitor, a drug composition comprising same, a preparation method therefor, and a use thereof in the treatment of JAK-related diseases comprising, for example, inflammatory diseases, autoimmune diseases, and cancers.
