This review addresses a central question in the field of complex systems: given a fluctuating
(in time or space), sequentially measured set of experimental data, how should one analyze …

Turbulence is ubiquitous, from oceanic currents to small-scale biological and quantum
systems. Self-sustained turbulent motion in microbial suspensions presents an intriguing …

To study how supernova feedback structures the turbulent interstellar medium, we construct
3D models of vertically stratified gas stirred by discrete supernova explosions, including …

Exact equations are given that relate velocity structure functions of arbitrary order with other
statistics.'Exact'means that no approximations are used except that the Navier–Stokes …

We present a direct numerical and analytical study of driven supersonic
magnetohydrodynamic turbulence that is believed to govern the dynamics of star-forming …

Transverse structure functions are obtained at high Reynolds numbers in atmospheric
turbulence (Taylor microscale Reynolds numbers between 10 000 and 15 000). These …

A puzzling feature of three-dimensional turbulence is the large deviations from Gaussianity
observed as one probes smaller and smaller scales. These deviations are usually believed …

We argue on the basis of empirical data that Kolmogorov's refined similarity hypothesis
(RSH) needs to be modified for transverse velocity increments, and propose an alternative …

The small-scale structure of grid turbulence is studied primarily using data obtained with a
transverse vorticity (ω3) probe for values of the Taylor-microscale Reynolds number Rλ in …

Using the largest database of isotropic turbulence available to date, generated by the direct
numerical simulation (DNS) of the Navier-Stokes equations on an 8192 3 periodic box, we …
