Concurrency control | Transaction processing
In databases and transaction processing, two-phase locking (2PL) is a concurrency control method that guarantees serializability.It is also the name of the resulting set of database transaction schedules (histories). The protocol uses locks, applied by a transaction to data, which may block (interpreted as signals to stop) other transactions from accessing the same data during the transaction's life. By the 2PL protocol, locks are applied and removed in two phases: 1. * Expanding phase: locks are acquired and no locks are released. 2. * Shrinking phase: locks are released and no locks are acquired. Two types of locks are used by the basic protocol: Shared and Exclusive locks. Refinements of the basic protocol may use more lock types. Using locks that block processes, 2PL may be subject to deadlocks that result from the mutual blocking of two or more transactions. (Wikipedia).

Total vs. phase-locked vs. non-phase-locked power
Time-frequency power can be decomposed into phase-locked and non-phase-locked components. This is a methodological distinction that helps understand which time-frequency power features are also phase-locked. The video uses files you can download from https://github.com/mikexcohen/ANTS_you
