@article{Qiu2016IntermittencyMI, title={Intermittency measurement in two-dimensional bacterial turbulence.}, author={Xiang Qiu and Long Ding and Yongxiang Huang and Ming Chen and Zhiming Lu and Yu-lu Liu and Quan Zhou}, journal={Physical review. E}, year={2016}, volume={93 6}, pages={ 062226 } }

In this paper, an experimental velocity database of a bacterial collective motion, e.g., Bacillus subtilis, in turbulent phase with volume filling fraction 84% provided by Professor Goldstein at Cambridge University (UK), was analyzed to emphasize the scaling behavior of this active turbulence system. This was accomplished by performing a Hilbert-based methodology analysis to retrieve the scaling property without the β-limitation. A dual-power-law behavior separated by the viscosity scale ℓ_…

An analysis of passive scalar (temperature) turbulence time series is presented to show the influence of large-scale structures in real turbulence and the efficiency of the Hilbert-based methodology, and corresponding scaling exponents ζ(θ)(q) provided by the Hilbert -based approach indicate that the Passive scalar turbulence field may be less intermittent than what was previously believed.
