MySQL 8.0 deliversNOWAITandSKIP LOCKEDalternatives in the SQL locking clause. Normally, when a row is locked due to anUPDATEor aSELECT ... FOR UPDATE, any other transaction will have to wait to access that locked row. In some use cases there is a need to either return immediately if a...
MySQL 8.0 delivers [Recursive] Common Table Expressions (CTEs). Non-recursive CTEs can be explained as “improved derived tables” as it allow the derived table to be referenced more than once. A recursive CTE is a set of rows which is built iteratively: from an initial set of rows, a ...
Cancer is an extraordinarily complex disease. Methods that are commonly used in physics can reduce the complexity of cancer to a manageable set of underlying principles and phenomena. In particular, Transport OncoPhysics views cancer as a disease of multiscale mass transport deregulation involving the...
A simple (monoatomic) ion is a single ion that has a deficiency or excess of electrons relative to protons. A simple cation is created by removing valence electrons from an uncharged atom. A simple anion is created by adding more valence electrons to an u...
MySQL 8.0 is an extremely exciting new version of the world’s most popular open source database with improvements across the board. Some key enhancements include: SQL Window functions, Common Table Expressions, NOWAIT and SKIP LOCKED, Descending Indexes, Grouping, Regular Expressions, Character Sets...
1A). Restricted to primates, alternative splicing of the H2AFV gene produces an isoform called H2A.Z.2.2, which has a shortened and unique C terminus. This alteration leads to destabilization of the nucleosome structure when H2A.Z.2.2 is incorporated into chromatin (15, 16). Download: ...
