Structural asymmetry as a fraud signature: detecting collusion with Heron's Information Coefficient

Allana Tavares Bastos, Tiago Alves Schieber, Renato Hadad +2

Fraud in public procurement remains a persistent challenge, especially in large, decentralized systems like Brazil's Unified Health System. We introduce Heron's Information Coeffic…

Network diffusion capacity unveiled by dynamical paths

T. A. Schieber, L. C. Carpi, P. M. Pardalos +3

Improving the understanding of diffusive processes in networks with complex topologies is one of the main challenges of today's complexity science. Each network possesses an intrin…

Assessing diversity in multiplex networks

L. C. Carpi, T. A. Schieber, P. M. Pardalos +4

Diversity, understood as the variety of different elements or configurations that an extensive system has, is a crucial property that allows maintaining the system's functionality…

Persistence and Stochastic Periodicity in the Intensity Dynamics of a Fiber Laser During the Transition to Optical Turbulence

Laura Carpi, Cristina Masoller

Many natural systems display transitions among different dynamical regimes, which are difficult to identify when the data is noisy and high dimensional. A technologically relevant…

Unveiling temporal correlations characteristic to phase transition in the intensity of a fibre laser radiation

Andres Aragoneses, Laura Carpi, Nikita Tarasov +4

We use advanced statistical tools of time-series analysis to characterize the dynamical complexity of the transition to optical wave turbulence in a fibre laser. Ordinal analysis a…

Information Theory Perspective on Network Robustness

Tiago A. Schieber, Laura Carpi, Alejandro C. Frery +3

A crucial challenge in network theory is the study of the robustness of a network after facing a sequence of failures. In this work, we propose a dynamical definition of network's…

Distinguishing noise from chaos: objective versus subjective criteria using Horizontal Visibility Graph

Martín Gómez Ravetti, Laura C. Carpi, Bruna Amin Gonçalves +2

A recently proposed methodology called the Horizontal Visibility Graph (HVG) [Luque {\it et al.}, Phys. Rev. E., 80, 046103 (2009)] that constitutes a geometrical simplification of…

Noisy-chaotic time series and the forbidden/missing patterns paradigm

Osvaldo A. Rosso, Laura C. Carpi, Patricia M. Saco +3

We deal here with the issue of determinism versus randomness in time series. One wishes to identify their relative importance in a given time series. To this end we extend i) the u…

Causality and the Entropy-Complexity Plane: Robustness and Missing Ordinal Patterns

Osvaldo A. Rosso, Laura C. Carpi, Patricia M. Saco +3

We deal here with the issue of determinism versus randomness in time series. One wishes to identify their relative weights in a given time series. Two different tools have been adv…
