Abstract: A salt of a nitrogen-containing fused heterocyclic compound or a crystal form thereof, and a preparation method therefor, a pharmaceutical composition thereof, and a use thereof, in particular, a salt of compound I as shown below or a crystal form thereof, and a preparation method, a pharmaceutical composition and a use. The salt of compound I or the crystal form thereof exhibits at least one of the following advantages: improved bioavailability, great mechanical properties, improved chemical stability, excellent fluidity, great compressibility, and improved dissolution characteristics.

Abstract: A hinge assembly comprises a first connecting member, a second connecting member, a first shaft, a second shaft, and a clockwork spring. The first connecting member includes a first pivot portion. The second connecting member includes a second pivot portion. The first shaft is pivotally connected to the first pivotal portion of the first connecting member and the second pivotal portion of the second connecting member. The second shaft is configured on the first connecting member and spaced from the first shaft. The clockwork spring includes a first end and a second end away from the first end; the first end fixed to the second shaft rod, the second end fixed to the second connecting member. When the second connecting member pivots with respect to the first connecting member, the arrangement of the clockwork spring can provide a more stable pivoting force for the second connecting member.

Abstract: System and methods for adaptive multi-granularity event groupings are provided. In embodiments, a method includes: determining to group IT operations data at a first level of granularity for similar events or at a second level of granularity for related events based on user input of a data grouping event; parsing, by an event parser, the IT operations data into one or more groups of similar events based on text information and parser rules in response to determining to group the IT operations data at the first level of granularity; obtaining user feedback indicating the one or more groups of similar events require modification; determining one or more keywords of the IT operations data using an artificial intelligence model in response to the user feedback; and updating the parser rules for the event parser based on the one or more keywords, thereby generating updated parser rules.

Abstract: An approach is provided that trains an artificial intelligence (AI) system, such as a neural network, to process IT ticket data. The approach receives IT tickets from various ticket sources. Ticket vectors corresponding to each of the IT tickets are computed. An analysis is performed using the ticket vectors and a node vector that corresponds to a network topology. The analysis is performed using a corpus of IT ticket data. An IT ticket model used by the AI system is trained based on the analysis. Responses are provided to requestors of the AI system using the trained IT ticket model.
