Pre-registration protocol: beyond-pairwise ordinal dependence (Res_pair, excess3) in Puerto Rico environmental multivariate time series around documented regime shifts (Aim 3 preliminary study)

Pre-registration protocol, written before any outcome was computed, for a preliminary real-data study of beyond-pairwise ordinal dependence in four-variable environmental time series from Puerto Rico. Systems. Confirmatory: (S2) daily mean discharge at four USGS gauges of the upp...

This protocol pre-registers a preliminary real-data study of beyond-pairwise ordinal dependence in four-variable environmental time series from Puerto Rico. It was finalized before any real-data outcome was computed. Systems. Confirmatory: (S2) daily mean discharge at four USGS g...

Systemic Tau as a homeostatic trigger for structural self-repair in event-driven networks

Systemic Tau, the mean pairwise Kendall rank correlation of module activity on a common event index, is used as the signal for a structural repair of an event-driven exclusive-or network. Because that mean is signed, an increase in one pair and a decrease in another can cancel. T...

Systemic Tau and Hierarchical Ordinal Conjunctions: A Relational Theory of Critical Transitions

Foundations paper (English, ~30 pp.) for a dual relational account of critical transitions in complex systems. Systemic Tau (τs) is an ordinal, multivariate measure of cross-variable coupling: sliding-window Kendall-type rank concordance tracks relational coherence rather than th...
