No persistent circadian oscillator at genome resolution: pseudo-coherence in gut microbiome dynamics
V. Troude, L. Takayasu, R. Maskawa +4
Diurnal rhythms in the gut microbiome are commonly read as evidence of host-driven entrainment or of microbial oscillators that synchronise to a common clock. We reanalyse hourly g…
Inferring Non-Normal Amplification Geometry from Multivariate Time Series
V. R. Saiprasad, V. Troude, D. Sornette
The paper introduces a data‑driven technique to infer the geometry of non‑normal transient amplification from multivariate time series by estimating a local linear operator and ext…
Toward a Geopolitical Crisis Observatory: Diagnosing Systemic Risk in News Flows Using Complex Systems Science
Didier Sornette
Complex-systems science provides media institutions with a rigorous framework to move from reactive reporting to anticipatory diagnosis. Critical events are understood as regime sh…
Non-Normal Route to Chaos
D. Sornette, V. R. Saiprasad, V. Troude
Deterministic chaos is usually associated with local spectral expansion: Jacobian eigenvalues are expected to exceed unity somewhere on the attractor. We show that this view is inc…
Social Amplification Dominates Collective Hazard Response
Xiaolei Chu, Guanren Zhou, Marco Broccardo +3
Large-scale hazards affect societies not only through direct physical impacts but also through emotions that spread across populations. Fueled by social amplification and networked…
HawkesRank: Event-Driven Centrality for Real-Time Importance Ranking
Didier Sornette, Yishan Luo, Sandro Claudio Lera
Quantifying influence in networks is important across science, economics, and public health, yet widely used centrality measures remain limited: they rely on static representations…
