Abstract: Example methods, apparatus, and systems associated with dynamic parallel magnetic resonance imaging (DpMRI) are presented. One example system facilitates separating data associated with a dynamic portion of a dynamic magnetic resonance image from data associated with a static portion of the dynamic magnetic resonance image. The system computes reconstruction parameters for a DpMRI reconstruction processes for both the dynamic portion of the image and the static portion of the image. The example system produces a DpMRI image based on separate reconstructions of the dynamic portion of a dynamic magnetic resonance image and the static portion of a dynamic magnetic resonance image. The separate reconstructions may depend on separate sets of reconstruction parameters and on separated static data and dynamic data.

One example method includes accessing data describing a mask for a value in a database table column to be masked. The example method may also include identifying a number of distinct values in the database table column to be masked and determining a field width for a mask to provide unique random numbers to mask the distinct values.

Abstract: Systems, methodologies, media, and other embodiments associated with supporting reference partitioned tables in a relational database are described. One example method includes identifying a partitioning strategy (e.g., range, list, hash) associated with a parent table that is related to a child table by a referential constraint. The example method may also include creating the child table to be a reference-partitioned table partitioned according to the partitioning strategy associated with the parent table. The example method may also include creating the child table to be equi-partitioned with respect to the parent table. The child table is not to replicate a partition key of the parent table but rather is to inherit a partitioning key associated with the parent table through a foreign key relationship.
