Abstract: Devices, systems and methods are provided for monitoring a replication service replicating data from a source database system to a destination database system. One method involves receiving, at the destination database system from the replication service over a network, a set of database transactions at the source database system, determining an expected tracking entry subsequent to the set of database transactions based at least in part on the one or more tracking entries in the set of database transactions, detecting an anomaly associated with replicating the data from the source database system in response to an absence of receiving, from the replication service, a subsequent set of database transactions at the source database system that includes the expected tracking entry within a threshold period of time, and initiating a remedial action in response to detecting the anomaly.

Abstract: An integrated circuit structure includes a first non-planar semiconductor device and a second non-planar semiconductor device. The first non-planar semiconductor device includes a first body, a first gate structure at least in part wrapped around the first body, and a first source region and a first drain region. The first body extends laterally between the first source and first drain regions. The second non-planar semiconductor device comprises a second body, a second gate structure at least in part wrapped around the second body, and a second source region and a second drain region. The second body extends laterally between the second source and second drain regions. In an example, a first height of the first body is at least 5% different from a second height of the second body. Each of the first and second bodies can be, for instance, a nanoribbon, nanosheet, or nanowire.

Abstract: A semiconductor structure includes a body including semiconductor material, and a gate structure at least in part wrapped around the body. The semiconductor structure further includes a source region and a drain region, the body laterally extending between the source and drain regions. The body has a middle region between first and second tip regions. In an example, the source region at least in part wraps around the first tip region of the body, and/or the drain region at least in part wraps around the second tip region of the body. In another example, the body includes a core structure and a peripheral structure (e.g., cladding or layer that wraps around the core structure in the middle region of the body) that is compositionally different from the core structure. The body can be, for instance, a nanoribbon, nanosheet, or nanowire or a gate-all-around device or a forksheet device.
