Abstract: The present disclosure provides a power supply circuit, a sensing device and an application thereof, comprising: a transducer; an energy storage assembly operably connected to the transducer; a power supply assembly electrically connected between the energy storage assembly and a power consumption module so that the energy storage assembly does not supply power to the power consumption module when the power consumption module is in a non-powered state and the output voltage is within a specified voltage interval; and the energy storage assembly is caused to supply power to the power consumption module when the output voltage is within a non-specified voltage interval.

Abstract: Intravascular delivery system is designed for a safe and efficient access to secondary and tertiary vascular structures, such as the branches of the coronary sinus, to enhance the delivery and deployment of various catheters, such as, for example, pacemaker electrical leads. The over-the-wire system features a straight, or alternatively shaped, micro-catheter distal tip of an inner catheter that seamlessly cooperates with a peel-away reinforced outer catheter. The inner catheter and the peel-away reinforced outer catheter are advanced in their engaged mode of operation towards (or beyond) the target site. Subsequently, the inner and outer catheters are disengaged, and the inner catheter is removed from the outer catheter. A pacemaker lead may be advanced over the wire inside the outer catheter to the target site for deployment. Subsequently, the outer catheter is easily split and may be rapidly removed from the blood vessel.

Abstract: Computer-readable media, methods, and systems are disclosed for utilizing partition-based locking mechanisms to improve execution of overlapping data definition language (DDL) and data manipulation language (DML) operations on a partitioned database table. A first node receives a DML statement associated with a first transaction. The first node acquires a intent exclusive lock on table metadata. A second node receives a DDL statement associated with a second transaction and acquires an exclusive metadata lock on the partitioned table metadata. Next, an intent exclusive lock is acquired for the relevant partition table data on the second node and an exclusive lock on table metadata on the second node. The second transaction waits for the DML operation of the first transaction to complete. Then the first transaction is committed. Finally exclusive locks are acquired on table data and metadata and the second transaction is executed and committed.

Also disclosed is a method of reducing perspiration comprising a step of topical application of the anhydrous antiperspirant composition.

Abstract: Computer-readable media, methods, and systems are disclosed for database table partition pruning based on statistical information associated with non-partition columns. A tree partition specification is received defining partitions for a plurality of computed column statistics. Respective partitions are created for the plurality of computed column statistics based on the tree partition specification. A request is received to compute statistics for a plurality of columns of the plurality of computed column statistics to result in a plurality of computed column statistics. In response to determining that one or more modifications have been made to the partitioned database, the plurality of computed column statistics is marked as invalid. The computed column statistics are refreshed in response to modifications of the partitioned table. Thereafter, the statistics are marked as valid. Unnecessary table partitions are pruned based on the statistics, and the associated query is executed.

Abstract: Computer-readable media, methods, and systems are disclosed for linear interval-based dynamic range partitioning in one or more database systems. A request is received by a database management system to insert a new row into a partitioned database table. The partitioned database table may include a plurality of existing partitions and a partition others partition. Based on determining that the new row should be inserted into the partition others partition a series of steps are performed. First, one or more new partitions are added to the partitioned database table. Then, the new row is inserted into the one of the one or more new partitions in the partitioned database table.

Abstract: A method may include generating a database table to include a first partition having a first range and a dynamic partition associated with an undefined range of a specified length. A record may be inserted into the database table. In response to one or more values of the record being outside of the first range of the first partition, a second partition having a second range of the specified length that includes the one or more values of the record may be generated. The record may be stored in the second partition. Moreover, a query on the database table may be executed by the first partition and/or the second partition of the database table. Related systems and articles of manufacture are also provided.

Abstract: A method for processing a query may include evaluating a query on a database table to identify a time based function included in the query. One or more partitions of the database table may be pruned from the query based at least on the partitions being associated with a first time range that does not overlap with a second time range associated with the time based function. An execution plan for the query may be generated to include a sequence of operations that avoids accessing the one or more partitions pruned from the query. The query may be executed based at least on the execution plan by at least accessing a second partition of the database table but not the first partition of the database table pruned from the query. Related systems and articles of manufacture are also provided.
