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…
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…
Pseudo-Coherence and Stochastic Synchronization: A Non-Normal Route to Collective Dynamics without Oscillators
V. Troude, D. Sornette
Collective temporal organization in complex systems is commonly attributed to synchronization, resonance, or proximity to dynamical instabilities. Here we identify a distinct mecha…
Eigenvector Geometry as a New Route to Criticality in Random Multiplicative Systems
Virgile Troude, Didier Sornette
Heavy-tailed fluctuations and power law distributions pervade physics, biology, and the social sciences, with numerous mechanisms proposed for their emergence. Kesten processes, wh…
Life as Non-Normal Chemical Accelerator
Didier Sornette, Virgile Troude
Life is commonly described as a self-organized, far-from-equilibrium process that maintains internal order by consuming free energy and exporting entropy. This thermodynamic view u…
