Abstract: The present disclosure relates to a rotary blood pump system. The rotary blood pump system may comprise an inflow conduit, an outflow conduit, a control system, and a power source. The present disclosure further relates to various inflow conduit assemblies comprising a conduit tip comprised of metal or polymer having an undulating opening surface that provides improved blood flow and washing properties while minimizing regions susceptible to stagnation, and optionally a resilient tip-protecting cage structure that reduces the risk of conduit tip suction events and suction-related injury of the wall of adjacent blood vessels or other blood containing structures. The present disclosure further relates to various outflow conduit assemblies with a conduit tip comprised of metal or polymer wherein the cross-sectional area of the lumen of the conduit or conduit tip is reduced to generate a localized jet-like fluid flow in a blood vessel segment adjacent to the conduit tip.

Abstract: Closed-loop melt pool size control for additive manufacturing is integrated with site-specific changes to a controller set-point. Site-specific control enables localized control of bead geometry and material properties in an additive manufacturing system, thus offering enhanced defect mitigation capabilities when compared with constant setpoint technologies. Trigger points, generated by the projection of a secondary geometry onto a primary geometry, mark locations of the volume of a part under manufacture where site-specific changes in setpoint occur. Through this technique, it is possible to manufacture a specific geometry that occurs beyond a predefined toolpath of a print head. Implications of this capability extend beyond localized control of bead geometry to potential mitigations of defects and functional grading of component properties.

Abstract: A method of reducing the emission of nitrogen oxides (NOx) during system startup of a power generating system may include igniting a combustion turbine thereby generating exhaust, supplying the exhaust to a catalyst bed comprising a selective catalytic reduction (SCR) catalyst, injecting an initial pulse of ammonia into the exhaust during a storage period such that the NOx reacts with the ammonia and is stored in the catalyst bed as ammonium nitrate (AN) during the storage period; and injecting a scheduled amount of ammonia into the exhaust during a transition period such that the stored AN is decomposed as temperatures increase and NOx is converted via standard and fast SCR reactions during the transition period.

Abstract: A data store may implement dynamic query predicates for processing queries. Query predicate indexes may be maintained for individual storage locations in a data store. The query predicate indexes may indicate data values not stored in the storage location that satisfy a query predicate in the query predicate index. The query predicate index may be populated when queries are received at the data store which include new query predicates. When queries are received that include query predicates that correspond to query predicates in the query predicate index, the index values for each of the storage locations may be evaluated. Based, at least in part, on the evaluation, particular storage locations may be identified to read for servicing the queries.

Abstract: Read-only nodes of a distributed database system may perform replicated database startup for common database storage. A read-only node may request a view of a database from a master node to initialize the read-only node for servicing queries. An indication of the view may be received and portions of data maintained for the distributed database may be read from a common data store maintaining the data for the database according to the indicated view of the database. In-memory data structures at the read-only node for servicing queries may be initialized based on the portions of data read from the common data store. The read-only node may then be made available for servicing queries.
