Abstract: This document describes techniques and devices for efficient handling of a resource control state change and multi-node connectivity. Instead of performing multiple radio resource control (RRC) procedures to change a resource control state of a user equipment (UE) and establish, modify, or release a connection with multi-node connectivity, the techniques described herein combine the multiple RRC procedures into a single RRC procedure that supports both a resource control state change and multi-node connectivity. In particular, a master node sends a resource control state and multi-node connectivity message that includes both state change information and multi-node connectivity information. With this single message, timing and power resources of the UE can be conserved and failures resulting from asynchronous communication of the state change information and the multi-node connectivity information can be avoided.

Abstract: Borehole images can be corrected using machine-learning models. For example, a system can train a machine-learning model based on a training dataset. The training dataset can include a first set of borehole images correlated to a second set of borehole images, where the second set of borehole images are less precise versions of the first set of borehole images. The system can then execute the trained machine-learning model in relation to an input borehole image to receive a corrected borehole image as output from the trained machine-learning model. The corrected borehole image can be a visually corrected version of the input borehole image. The system may then perform one or more operations based on the corrected borehole image, such as generating a graphical user interface that includes the corrected borehole image for display on a display device.
