WebMay 21, 2012 · The phase locking value (PLV) was calculated between every pair of valid ICs for which a subject had one in each of two clusters. Phase cross-coherence (PLV) values were obtained using the following formula: C C 1, 2 ( f, t) = 1 N ∑ k = 1 N W 1, k f, t W 2, k * f, t W 1, k f, t W 2, k f, t. Web»State Locking. If supported by your backend, Terraform will lock your state for all operations that could write state. This prevents others from acquiring the lock and potentially corrupting your state. State locking happens automatically on all operations that could write state. You won't see any message that it is happening.

WebOct 29, 2024 · Phase-Locking Value: The phase-locking value (PLV) [45, 60] looks only at the phase consistency across trials.
