We study scaling relations of compressible isothermal strongly magnetized turbulence using numerical simulations with resolution 5123. We find a good correspondence of our results with the Fleck (1996) model of compressible hydrodynamic turbulence. In particular, we find that the density-weighted velocity, i.e. u ≡ ρ1/3v, proposed in Kritsuk et al. (2007) obeys the Kolmogorov scaling, i.e. Eu(k...

HYPOTHESIS Laparoscopic pancreatic resection can safely duplicate all of the open pancreatic procedures. DESIGN A prospective evaluation of laparoscopic pancreatic resection. Surgical procedure, postoperative course, and follow-up data were collected. SETTING Department of Abdominal Surgery at Haut-Lévêque Hospital, Centre Hospitalier Universitaire de Bordeaux, Bordeaux, France. PATIENTS ...

We study scaling relations of compressible strongly magnetized turbulence. We find a good correspondence of our results with the Fleck (1996) model of compressible hydrodynamic turbulence. In particular, we find that the density-weighted velocity, i.e. u ≡ ρv, proposed in Kritsuk et al. (2007) obeys the Kolmogorov scaling, i.e. Eu(k) ∼ k −5/3 for the high Mach number turbulence. Similarly, we f...

Multiplicative processes and multifractals proved useful in various applications ranging from hydrodynamic turbulence to computer network traffic, to name but two. It was recently shown and explained how and why multifractal analysis could be interestingly and fruitfully placed in the more general framework of infinitely divisible cascades. The aim of this contribution is to design processes, c...

We simulate the dynamics of phase transition in radiatively cooling interstellar gas in three dimensions with a high order hydrodynamic method. We have previously shown (Kritsuk & Norman 2002a) in simulations with non-equilibrium initial conditions that thermal instability induces supersonic turbulence as a by-product of the phase transition which leads to formation of multiphase medium. We rel...

We perform three-dimensional (3D) compressible MHD simulations over many dynamical times for an extended range of sonic and Alfvén Mach numbers and analyze the statistics of 3D density and 2D column density, which include probability distribution functions, spectra, skewness, kurtosis, She-Lévêque exponents, and genus. In order to establish the relation between the statistics of the ob-servable...
