Universal properties of three-dimensional magnetohydrodynamic turbulence: Do Alfv\'en waves matter?
, 2005 We analyse the effects of the propagating Alfv\'en waves, arising due to non-zero mean magnetic fields, on the nonequilibrium steady states of three-dimensional (3d) homogeneous Magnetohydrodynamic (MHD) turbulence. In particular, the effects of Alfv\'en

Complexity Analysis of Bubble Plumes in Power Law Fluids Based on Chaos Theory
Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT In order to reveal the complexity of the internal flow of bubble plume in power law fluid, the flow characteristics and chaotic characteristics of plume are studied by experiment and theory. The chaotic characteristic parameters (correlation dimension D, K entropy, and Lyapunov exponent λ) of gas velocity under different superficial gas ...

Fourier Mass Lower Bounds for Batchelor‐Regime Passive Scalars
Communications on Pure and Applied Mathematics, EarlyView.ABSTRACT Batchelor predicted that a passive scalar ψν$\psi ^\nu$ with diffusivity ν$\nu$, advected by a smooth fluid velocity, should typically have Fourier mass distributed as |ψ̂ν|2(k)≈|k|−d$|\widehat{\psi }^\nu |^2(k) \approx |k|^{-d}$ for |k|≪ν−1/2$|k| \ll \nu ^{-1/2}$.

When Does Top Management Team Diversity Matter in Large Organizations?
Journal of Organizational Behavior, EarlyView.ABSTRACT Top management teams (TMTs) drive strategic leadership, but there is little clarity on when the composition of these upper echelons most impacts organization performance. Drawing from the categorization‐elaboration model, we study an 18‐year sample of approximately 4500 organizations and over 32 000 executives and find a positive relationship ...

Fetal Ductal Constriction, Pulmonary Hypertension and Atrial Septum Mobility
Journal of Ultrasound in Medicine, EarlyView.Objectives Fetuses with ductal constriction (FDC), pulmonary hypertension and right ventricular overload after maternal exposure to PGE2 inhibitors—nonsteroidal anti‐inflammatory drugs (NSAIDs) or polyphenols (PF)—have increased septum primum excursion index (SPEI), the ratio between maximal septum primum displacement and left atrial diameter.

HI Density Distribution Driven by Supernovae: A Simulation Study
, 2006 We model the complex distribution of atomic hydrogen (HI) in the interstellar medium (ISM) assuming that it is driven entirely by supernovae (SN). We develop and assess two different models.
