Irreversibility and complex network behavior of stream flow fluctuations

Network robustness and irreversibility of information diffusion in Complex networks

Complex networks are characterized based on a newly proposed parameter, “degree of diffusion ̨”. It defines the ratio of information adopters to non-adopters within a diffusion process over consecutive penetration depths. Furthermore, the perfectness of a social network is evaluated by exploring different variations of ̨ such as the reverse diffusion ( ̨reverse) and the random-kill-diffusion (RK...

Irreversibility and Dephasing from Vacuum Fluctuations

Large Fluctuations and Irreversibility in Nonequilibrium Systems

Large rare fluctuations in a nonequilibrium system are investigated theoretically and by analogue electronic experiment. It is emphasized that the optimal paths calculated via the eikonal approximation of the Fokker-Planck equation can be identified with the locus of the ridges of the prehistory probability distributions which can be calculated and measured experimentally for paths terminating ...

Analogue experiments on irreversibility of classical fluctuations

LARGE FLUCTUATIONS occur universally in Nature. They are responsible for e.g. nucleation at phase transitions, chemical reactions, mutations in DNA sequences, protein transport in biological cells, and failures of electronic devices. The idea that they provide a conceptual bridge between microscopic and macroscopic motion underlies many discussions2−5 of how the irreversible thermodynamic behav...

OFFPRINT Testing time series irreversibility using complex network methods

The absence of time-reversal symmetry is a fundamental property of many nonlinear time series. Here, we propose a new set of statistical tests for time series irreversibility based on standard and horizontal visibility graphs. Specifically, we statistically compare the distributions of time-directed variants of the common complex network measures degree and local clustering coefficient. Our app...
