Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for automatic generative learned process coaching. One of the methods includes receiving interaction data for a user for interactions occurring in multiple software services used by the user during handling of a case. A case type of the case is determined and a machine learning model that includes learned model interaction behavior for the case type is identified. Interaction data for the user is compared to the learned model interaction behavior for the case type. Action data is generated for the user that includes an interaction behavior improvement recommendation that is determined based on the comparing of the interaction data for the user to the learned model interaction behavior for the case type. Action is taken based on the action data.

Abstract: In order to improve the mechanical stability of an X-ray grating with top bridges for X-ray dark field imaging and/or X-ray phase contrast imaging, it is proposed to reduce or prevent the undesired high stress on the top bridges by a change in the manufacturing process. Specifically, it is proposed to electroplate the top bridges after the bending. In other words, the electroplating of the top bridges is performed on the bent geometry.
