Abstract: A source table organized into a set of batch units is accessed. The source table comprises a column of data corresponding to a semi-structured data type. One or more indexing transformations for an object in the column are generated. The generating of the one or more indexing transformation includes converting the object to one or more stored data types. A pruning index is generated for the source table based in part on the one or more indexing transformations. The pruning index comprises a set of filters that index distinct values in each column of the source table, and each filter corresponds to a batch unit in the set of batch units. The pruning index is stored in a database with an association with the source table.

Abstract: A source table organized into a set of micro-partitions is accessed by a network-based data warehouse. A pruning index is generated based on the source table. The pruning index comprises a set of filters that indicate locations of distinct values in each column of the source table. A query directed at the source table is received at the network-based data warehouse. The query is processed using the pruning index. The processing of the query comprises pruning the set of micro-partitions of the source table to scan for data matching the query, the pruning of the plurality of micro-partitions comprising identifying, using the pruning index, a sub-set of micro-partitions to scan for the data matching the query.

Abstract: A table organized into a set of batch units is accessed. A set of N-grams are generated for a data value in the source table. The set of N-grams include a first N-gram of a first length and a second N-gram of a second length where the first N-gram corresponds to a prefix of the second N-gram. A set of fingerprints are generated for the data value based on the set of N-grams. The set of fingerprints include a first fingerprint generated based on the first N-gram and a second fingerprint generated based on the second N-gram and the first fingerprint. A pruning index that indexes distinct values in each column of the source table is generated based on the set of fingerprints and stored in a database with an association with the source table.

Abstract: The current document is directed to improved PTA methodologies that significantly decrease the risks of persistent blood-vessel-wall distention and subsequent restenosis and the risks of PTA-induced dissection, hematoma, and pseudoaneurysm when used to treat blood vessels. Similar improved percutaneous-transluminal-interventional methods are used to treat non-vascular vessels. The improved methods include initial selection of balloon length and inflation pressure for initial treatment of primary lesions to minimize the risks of over-inflation and generation of undesirable localized forces during balloon inflation. The improved methods further include higher-pressure treatment of remaining secondary lesions that also minimizes the risks of over-inflation and generation of undesirable localized forces. The improved methods can be practiced using differently sized balloons and conventional instrumentation, but may be facilitated by use of balloon-length-adjustable catheters.

Abstract: An optical arrangement for a lithography apparatus has a microsystem with a mirror array. A respective mirror of the mirror array is set up to reflect working light of the lithography apparatus on its front side and also a measuring beam on its rear side. One or more radiation sources, which are provided outside the microsystem, are set up to provide the respective measuring beam. One or more sensor units are set up to sense a tilting angle of a respective mirror in dependence on the respectively reflected measuring beam.

Abstract: A query directed at a table organized into a set of batch units is received. The query comprises a predicate for which values are unknown prior to runtime. A set of values for the predicate are determined based on the query. An index access plan is created based on the set of values. Based on the index access plan, the set of batch units are pruned using a pruning index associated with the table. The pruning index comprises a set of filters that index distinct values in each column of the table. The pruning of the set of batch units comprises identifying a subset of batch units to scan for data that satisfies the query. The subset of batch units of the table are scanned to identify data that satisfies the query.

Abstract: MEMS devices include fluid confinement structures on either a fixed part of a substrate and/or on a suspended element. The fluid confinement structures may be configured to confine a viscoelastic fluid in a limited part of a gap between one or more vertical sidewalls of both the fixed part of the substrate and either the suspended element or the drive beam or both the suspended element and drive beam such that one part of the gap is bridged by the fluid and another part of the gap is not, The structures may be configured to prevent flow of the fluid to other parts of the gap.
