We compare the properties of ordinary strong magnetohydrodynamic (MHD) turbulence in a strongly magnetized medium with the recently discovered viscosity-damped regime. We focus on energy spectra, anisotropy, and intermittency. Our most surprising conclusion is that in ordinary strong MHD turbulence the velocity and magnetic fields show different high-order structure function scalings. Moreover ...

recently, the hypothesis in which memory and information would be stored as magnetic forms in astrocytes is expanding and neuromagnetic interactions between neurons and neighboring astrocytes in neocortex have potential to be the basis of memory formation. it has been proposed that all sorts of information may be maintained in form of neuronal activity-associated magnetic fields (naamfs) and th...

Previous work on the emission from isolated old neutron stars (IONSs) accreting from the interstellar medium (ISM) has focused on gravitational captureÈi.e., Bondi accretion. We propose a new class of sources that accrete via magnetic interaction with the ISM. While for the Bondi mechanism the accretion rate decreases with increasing neutron star velocity, in magnetic accretors (MAGACs) M0 Bond...

We investigate the consequences of magnetic flares on the surface of asymptotic giant branch (AGB) and similar stars. In contrast to the solar wind, in the winds of AGB stars the gas cooling time is much shorter than the outflow time. As a result, we predict that energetic flaring should enhance, rather than inhibit, dust formation around AGB stars. Analysis of an archival ROSAT X-ray spectrum ...

We present arcsecond resolution observations from the VLA1 with full Stokes polarimetry of the ground-state satellite line of the hydroxyl molecule (OH) at 1720.53 MHz (2Π 3 2 , J = 32 , F = 2 → 1) toward three Galactic supernova remnants: W 28, W 44, and IC 443. The total number of individual OH(1720 MHz) “spots” we detect in each of these three remnants is 41, 25 and 6, respectively. The OH(1...

in recent years, the scientists have focused on nanotecnology and its applications as the most important fields of research and development. the use of nanoparticles offers many advantages, due to their unique size and physical properties. magnetic iron oxide nanoparticles have been used in many fields, because of their unique properties such as large specific surface area and convenient separa...

Brown dwarf formation and star formation efficiency are studied using a nested grid simulation that covers five orders of magnitude in spatial scale (10– 0.1AU). Starting with a rotating magnetized compact cloud with a mass of 0.22M⊙, we follow the cloud evolution until the end of main accretion phase. Outflow of ∼ 5 km s emerges ∼ 100 yr before the protostar formation and does not disappear un...

We have done a statistical analysis of Very Long Baseline Array (VLBA) data of water masers in the star-forming regions (SFRs) Cepheus A and W75 N, using correlation functions to study the spatial clustering and Doppler-velocity distribution of these masers. Two-point spatial correlation functions show a characteristic scale size for clusters of water maser spots .1 AU, similar to the values fo...
