Abstract: The present invention relates to the use of a pyrrolopyrimidine compound and a pharmaceutical composition thereof for treating chronic graft versus host disease, and particularly relates to the use of a compound of formula (I), a stereoisomer thereof, or a pharmaceutically acceptable salt thereof, and a pharmaceutical composition thereof for treating chronic graft versus host disease.

Abstract: A system includes a video traffic information analysis module configured to acquire a traffic condition parameter of a road network from video traffic information; a traffic condition prediction module configured to predict a traffic condition in a future period of time according to the traffic condition parameter to obtain a traffic condition prediction result; an actual traffic condition assessment module configured to assess an actual traffic condition based on the traffic condition parameter and according to a traffic condition evaluation model to obtain an actual traffic condition assessment result; and a traffic control decision module configured to determine a control scheme for a controllable traffic element using an optimization algorithm according to the traffic condition prediction result and the actual traffic condition assessment result.

Abstract: A toilet bowl and cover assembly includes a toilet bowl and a cover. The toilet bowl has an upper seat portion, a lower discharge portion, a top opening formed on the upper seat portion, a bottom drainage opening formed on the lower discharge portion. The upper seat portion has a curved cross-sectional shape and a first offset surface formed on a front side of the upper seat portion. The cover includes a seat panel having a through cover opening. The seat panel has an exterior contour substantially corresponding to that of the curved cross-sectional shape of the upper seat portion of the toilet bowl, and a second offset surface formed on a front side of the cover panel.
