International Classification:

A61M 2500

US Classification:

604508, 604507, 514 2, 514 44, 514 54

Abstract:

Methods are provided for locally administering an agent to a host. Specifically, the subject methods provide for the local administration of an agent to an interstitial space of a host. In the subject methods, an agent is retroinfused into a vessel of a host, typically a vein, under conditions sufficient for the agent to enter an interstitial space of the host proximal to the vessel location into which the agent is retroinfused. In practicing the subject methods, the agent is administered to the host in combination with the production of vascular stress at the site of administration, where the vascular tissue stress is sufficient to provide for transport of the agent from the vascular site of deposition into the target interstitial space. In a preferred embodiment, the agent is retroinfused at a pressure sufficient to provide for mechanical stress on the vessel proximal to the target interstitial space. Also provided are kits for use in practicing the subject methods.

International Classification:

G06F 16/901
G06F 16/903

Abstract:

The disclosed embodiments provide a system for processing queries of a graph database storing a graph, wherein the graph comprises a set of edges defined by a first linkage, a second linkage, and a third linkage. During operation, the system maintains the base version of an index of the graph database. Upon branching a version of the graph database from a first offset representing a virtual time in the base version of the graph database, the system creates a branched version of the index from a second offset corresponding to the virtual time in the base version of the index. The system then processes queries of the graph database based on the offsets and references from the branched version of the index to the base version of the index.

Abstract:

The disclosed embodiments provide a system for managing inter-process communication. During operation, the system executes a block storage manager for managing shared memory that is accessed by a write process and multiple read processes. Next, the block storage manager manages one or more data structures storing mappings that include block identifiers (IDs) of blocks representing chunks of the shared memory, files in the blocks, and directories containing the files. The block storage manager then applies an update by the write process to a subset of the blocks by atomically replacing, in the one or more data structures, a first directory containing an old version of the subset of the blocks with a second directory containing a new version of the subset of the blocks.

International Classification:

G06F 17/30

Abstract:

The disclosed embodiments provide a system for managing a materialized view of data in a data store. During operation, the system obtains a first creation time of a first materialized view of the data in the data store. Next, the system verifies that the first materialized view is not affected by deletions applied to the data since the first creation time. The system then identifies one or more additions to the data that are not included in the first materialized view. Finally, the system applies the additions to the first materialized view to maintain an eventual consistency of the first materialized view with the data store.

International Classification:

G06F 17/30

Abstract:

The disclosed embodiments provide a system for migrating traffic between versions of a distributed service. During operation, the system executes a set of nested controllers for migrating traffic from a first version of a distributed service to a second version of the distributed service. Next, the system uses a set of rules to select, by the set of nested controllers, a first deployment environment for processing a query of the distributed service. The system then transmits the query to the first deployment environment.

International Classification:

G06F 17/30

Abstract:

The disclosed embodiments provide a system for processing queries of a graph database. During operation, the system executes one or more processes for providing the graph database storing a graph, wherein the graph includes a set of nodes, a set of edges between pairs of nodes in the set of nodes, and a set of predicates. Next, the system obtains, from the query, an aggregation by a first attribute and a grouping by a second attribute. The system then uses the second attribute to generate a set of groupings of records in the graph database. For each grouping in the set of groupings, the system applies the aggregation to the first attribute in a subset of the records in the grouping to generate an aggregation result. Finally, the system uses the aggregation result to provide a response to the query.

Abstract:

The disclosed embodiments provide a system for processing queries of a graph database. During operation, the system executes a set of processes for processing queries of a graph database storing a graph, wherein the graph comprises a set of nodes, edges between pairs of nodes, and a set of predicates. Next, the system obtains a first query containing a first tuple and a second query containing a first subset of edges. The system transforms the first tuple into a second subset of edges and the first subset of edges into a second tuple. Finally, the system uses the second subset of edges to generate a first result of the first query and the second tuple to generate a second result of the second query, and provides the first result in a first response to the first query and the second result in a second response to the second query.

International Classification:

Abstract:

The disclosed embodiments provide a system for processing queries of a graph database. During operation, the system executes a set of processes for processing queries of a graph database storing a graph, wherein the graph comprises a set of nodes, a set of edges between pairs of nodes in the set of nodes, and a set of predicates. When a query of the graph database is received, the system obtains, from the query, a compound comprising a compound type and a set of identity-giving nodes. Next, the system uses the compound to access a tuple for storage in a log-based representation of the graph database, wherein the tuple includes the compound type and the identity-giving nodes. The system then uses the tuple to generate a result of the query and provides the result in a response to the query.
