OBJECTIVES To assess American newspaper coverage regarding racial and ethnic minority health disparities (MHDs). METHODS LexisNexis was queried with specific word combinations to elicit all MHD articles printed in 257 newspapers from 2000-2004. The full texts were read and articles categorized by racial/ethnic group and specific MHD topics mentioned. RESULTS In the five years from 2000-2004...

[1] The wake region of Titan is an important component of Titan’s interaction with its surrounding plasma and therefore a thorough understanding of its formation and structure is of primary interest. The Cassini spacecraft passed through the distant downstream region of Titan on 18:59:30 UT Dec. 26, 2005, which is referred to as the T9 flyby and provided a great opportunity to test our understa...

Context. We present a detailed study of localised magnetohydrodynamical (MHD) instabilities occuring in two– dimensional magnetized accretion disks. Aims. We model axisymmetric MHD disk tori, and solve the equations governing a two–dimensional magnetized accretion disk equilibrium and linear wave modes about this equilibrium. We show the existence of novel MHD instabilities in these two–dimensi...

We re-analyse the resonant spin–flavour (RSF) solutions to the solar neutrino problem in the framework of analytic solutions to the solar magneto-hydrodynamics (MHD) equations. By substantially eliminating the arbitrariness associated to the magnetic field profile due to both mathematical consistency and physical requirements we propose the simplest scheme (MHD-RSF, for short) for solar neutrin...

We present numerical simulations of electron magnetohydrodynamic (EMHD) and electron reduced MHD (ERMHD) turbulence. Comparing scaling relations, we find that both EMHD and ERMHD turbulence show similar spectra and anisotropy. We develop new techniques to study anisotropy of EMHD turbulence. Our detailed study of anisotropy of EMHD turbulence supports our earlier result of k‖ ∝ k ⊥ scaling, whe...

BACKGROUND The assessment of physical activity and energy expenditure is relevant to the care of maintenance haemodialysis (MHD) patients. In the current study, we aimed to evaluate measurements of physical activity and energy expenditure in MHD patients from different centres and countries and explored the predictors of physical activity in these patients. METHODS In this cross-sectional mul...

The limitations of Hall MHD as a model for turbulence in weakly collisional plasmas are explored using quantitative comparisons to Vlasov-Maxwell kinetic theory over a wide range of parameter space. The validity of Hall MHD in the cold ion limit is shown, but spurious undamped wave modes exist in Hall MHD when the ion temperature is finite. It is argued that turbulence in the dissipation range ...

BACKGROUND MicroRNAs (miRNAs) are small ribonucleotides regulating gene expression. MicroRNAs are present in the blood in a remarkably stable form and have emerged as potential diagnostic markers in patients with cardiovascular disease. Our study aimed to assess circulating miR-133a levels in MHD patients and the relation of miR-133a to cardiac hypertrophy. METHODS We profiled miRNAs using RN...

For numerical simulations to be e;ective tools in plasma propulsion research, a high-order accurate solver that captures MHD shocks monotonically and works reliably for strong magnetic =elds is needed. For this purpose, a characteristics-based scheme for the MHD equations, with "ux limiters to improve spatial accuracy, has been developed. In this method, the symmetric form of the MHD equations,...

We used magnetohydrodynamic (MHD) simulations of interstellar turbulence to study the probability distribution functions (PDFs) of increments of density, velocity, and magnetic field. We found that the PDFs are well described by a Tsallis distribution, following the same general trends found in solar wind and Electron MHD studies. We found that the PDFs of density are different in subsonic and ...
