Diffusion tensor microimaging at 16.4 T with 40 μm isotropic voxels was used to investigate anisotropic water diffusion in prostate tissue at spatial resolution approaching the cellular scale. Nine normal glandular tissue samples were collected from the peripheral zone of six formalin fixed radical prostatectomy specimens. Fibromuscular stromal tissue exhibited microscopic diffusion anisotropy ...

We evaluated the integrity of the white matter tract using diffusion-tensor magnetic resonance imaging in children with language impairments who exhibited a structurally normal brain on conventional magnetic resonance imaging, and compared it with age-matched normal children. After generating fractional anisotropy and color-coded vector maps, fractional anisotropy values of the major white matt...

We report on the photoinduced changes of the electronic properties of YBa2Cu3Ox (x ≈ 6.6) thin films, focussing on the electrical anisotropy in the normal and the superconducting state. The latter was determined from magnetoconductivity measurements, performed before and after light excitation, and fitting the experimental results to the Aslamazov–Larkin theory of superconducting order-paramete...

Cosmic ray particles are more rapidly accelerated in oblique shocks, with the magnetic field inclined with respect to the shock normal direction, than in parallel shocks, as a result of mirror reflection at the shock surface and slower diffusion in the shock normal direction. We investigate quantitatively how these effects contribute to reducing the acceleration time over the whole range of mag...

The effects of diffusion anisotropy on pattern formation in bistable media are studied using a FitzHugh-Nagumo reaction-diffusion model. A relation between the normal velocity of a front and its curvature is derived and used to identify distinct spatiotemporal patterns induced by the diffusion anisotropy. In a wide parameter range anisotropy is found to have an ordering effect: initial patterns...

a preliminary palaeomagnetic results from basalt outcrops in northeast lebanon is reported. the remanence carrier of the characteristic magnetisation is magnetite.  both variations of susceptibility and anisotropy directional data show that the measured directions of thermoremanent magnetisation (trm) are representative of the ambient field at the time of cooling of these basalts through their ...
