Abstract: Techniques are disclosed relating to implementing database table schema changes. A computer system stores a source table associated with a current schema that is used to process transactions against a database. The computer system creates a target table associated with a temporary schema, where the target table includes one or more database table schema changes relative to the source table. The computer system provisions synchronization triggers to capture record changes made to the source table and replicate them on the target table. The computer system then performs a copy operation to copy data stored in the source table to the target table while transactions operate on the source table. After completing the copy operation, the computer system performs a schema swap operation to associate the current schema with the target table and not the source table so that the target table is used to process transactions against the database.

Abstract: Systems and methods described herein enable user-aware and application-aware dynamic slicing for mobile networks. A network device in a provider network receives a dynamic slice request from a client application. The dynamic slice request includes authorization credentials and a quality of service (QoS) indication for the client application. In response to the dynamic slice request, the network device generates a traffic descriptor value. The traffic descriptor value includes an access token that indicates the QoS authorized for the client application. The network device pushes updated UE Route Selection Policy (URSP) rules to a modem of the UE device, and also separately directs the traffic descriptor value to the client application. The network device receives, from the UE device, a protocol data unit (PDU) session establishment request that includes network slice selection information based on the traffic descriptor value.

Abstract: The technology provides an efficient delta-of-delta compression process, which is designed to take advantage of large register configurations such as 128-bit or 256-bit registers. The process employs predictors to predict particular data values, such as for a timeseries of data. The timeseries is stored as a vector of points in memory. Predictors leverage instruction size and register size so that data storage is highly efficient, and processing latency is minimized or otherwise reduced. The process can be particularly beneficial for certain architectures, including single instruction, multiple data (“SIMD”) architectures, as it allows for the reuse of operands between iterations. This reduces the number of register loads required by the processing system, such as by omitting one or more load instructions that would otherwise be required. Moreover, decompression of compressed data generated by this approach can be performed very quickly, which can be important for data retrieval.

Abstract: Forces applied to the channel regions of semiconductor slabs in a first direction relative to the semiconductor slab, can create strains in the crystal structure that improve carrier mobility to improve drive strength in the channel region. In a three-dimensional (3D) FET structure, a work function metal layer is provided on opposing faces of semiconductor slabs to cause a force to be exerted on the channel regions in a first direction corresponding to current flow. The force in the first direction is either tensile force or compressive force, depending on a FET type (N or P) employing the semiconductor slab, and is provided to create strain in a crystalline structure of the semiconductor slab to improve carrier mobility in the channel region. Increasing carrier mobility in the channel regions in a 3D FET structure increases drive strength of the 3D FET, which saves area in an integrated circuit.
