Abstract: There are provided systems and methods for pairwise graph querying, merging, and computing for account linking. A service provider may provide an account graph system to identify pairwise similarities between different accounts based on shared data that may be identified through one or more linking characteristics. When providing pairwise graph similarities, a service provider may receive a query identifying two or more accounts and/or an account with a parameter for graph exploration and querying. The service provider may utilize connection, link, or relationship graphs, queried and generated using a graph database, to determine pairwise similarities between the designated seed account and one or more selected accounts. The graph may include vertices for different queried data points and edges connecting such queries, where directionality of the edges or other vectors may be used to identify links or hops between accounts for data querying and exploration.

Abstract: A computer-implemented method for providing location-based appointment operations is disclosed. The method includes receiving input indicating an instruction to perform an action related to appointments. Responsive to the input indicating the instruction to perform the action related to appointments, it may be determined that a computing device is proximate to a physical location where locations are schedulable. Then, responsive to determining that the computing device is proximate to the physical location, information related to scheduling appointments at the physical location is received via a network. The indication based on the received information is presented at the computing device. Input requesting an action in relation to an appointment at the physical location may be received at the computing device. An indication to initiate the requested action may be sent via the network. Related computing devices and computer-readable media are also disclosed.

Abstract: An alternate root tree or graph structure for ray and path tracing enables dynamic instancing build time decisions to split any number of geometry acceleration structures in a manner that is developer transparent, nearly memory storage neutral, and traversal efficient. The resulting traversals only need to partially traverse the acceleration structure, which improves efficiency. One example use reduces the number of false positive instance acceleration structure to geometry acceleration structure transitions for many spatially separated instances of the same geometry.

The packet processing circuitry is to: capture a network packet transmitted by a software application running on an integrated computing system; capture, at time of transmission of the network packet, a value of a physical clock as a receive timestamp for subscriber entities that are running on the integrated computing system; store the receive timestamp in the local register; associate the receive timestamp from the local register with a first packet copy of the network packet; insert the first packet copy to a first receive pipeline of a first subscriber entity; associate the receive timestamp from the local register with a second packet copy of the network packet; and insert the second packet copy to a second receive pipeline of a second subscriber entity.

Abstract: A method includes providing a plurality of processes interconnected by a network, each of the plurality of processes being configured to hold a block of data destined for others of the plurality of processes. A set of data for all-to-all data exchange is received from one or more of the processes. The set of data is configured as a plurality of blocks of data in a matrix as matrix data, the matrix being distributed among the plurality of processes. The matrix data is transposed by changing the position of selected blocks of data of the plurality of blocks of data relative to the other blocks of data of the plurality of the blocks of data, without changing the structure of each of the blocks of data. The transposed matrix data is over the network and is then received, repacked, and conveyed to destination processes.

Abstract: This disclosure is directed to prosthetic heart valves having expansion and locking assemblies. As one example, a prosthetic heart valve can include an annular frame and an expansion and locking assembly that is configured to radially expand the frame to a radially expanded state and/or to lock the prosthetic valve in the radially expanded state to prevent the prosthetic valve from collapsing (i.e., radially compressing).

In some examples, the actuator member can extend through openings in vertical struts of the frame.
