Abstract: A first storage system in one illustrative embodiment is configured to participate in a replication process with a second storage system. The first storage system detects a replication failure condition or other condition requiring termination of a synchronous replication mode of the replication process, and responsive to the detected condition, captures a snapshot of source data that is subject to replication from the first storage system to the second storage system as part of the replication process. The first storage system terminates the synchronous replication mode of the replication process, initiates an asynchronous replication mode of the replication process, executes an asynchronous-to-synchronous transition cycle scan operation for the replication process utilizing the captured snapshot, and resumes the synchronous replication mode of the replication process responsive to successful completion of the asynchronous-to-synchronous transition cycle scan operation.

Abstract: Methods, apparatus, and computer-readable media are described for notching a 6 GHz channel. A station associates with an access point on a 6 GHz band. A notching pattern indication is decoded from data received from the AP after associating with the AP.

The notching pattern indicates a width of a notching region and a location of the notching region within the channel. The notching region covers bandwidth occupied by an incumbent system within the channel. A physical layer convergence procedure (PLCP) protocol data unit (PPDU) is encoded for transmission on the channel to the AP. The PPDU is encoded to exclude transmission within the notching region.

Abstract: In accordance with implementations of the subject matter described herein, there is proposed a solution of visual stylization of stereoscopic images. In the solution, a first feature map for a first source image and a second feature map for a second source image are extracted. The first and second source images correspond to first and second views of a stereoscopic image, respectively.

Through the solution, a disparity between two source images of a stereoscopic image are taken into account when performing the visual style transfer, thereby maintaining a stereoscopic effect in the stereoscopic image consisting of the target images.
