Abstract In this paper, the Cauchy problem for one-dimensional compressible isentropic magnetohydrodynamic (MHD) equations with no vacuum at infinity is considered, but initial can be permitted inside region. By deriving a priori ν (resistivity coefficient)-independent estimates, we establish non-resistive limit of global strong solutions large data. Moreover, as by-product, well-posedness resi...

BACKGROUND AND PURPOSE Our goal was to characterize the geometry of simple-lobed cerebral aneurysms and to find the absolute size of these lesions from angiographic tracings. METHODS Measurements of angiographic neck width (N), dome height (H), dome diameter (D), and semi-axis height (S) were obtained from tracings of 87 simple-lobed lesions located at the basilar bifurcation (BB), middle cer...

a detailed study of the exploited geothermal field of travale in italy was conducted using magnetotelluric (mt) data in 2004. this paper detects the main features of the conductivity structures of this area. for subsurface mapping purpose, the long period natural-field mt method proved very useful. for processing and modeling of the mt data, 2d inversion schemes were used and to have the best p...

We used transient electromagnetic (TEM) to map the hydrogeological structures in Choushui River Alluvial Fan Yunlin County of central Taiwan. A total 63 TEM measurements were collected using FASTSNAP system with 50 × m in-loop configurations middle and distal fan. The 1D model, based on prior information, was constructed from inverted soundings. Results showed a thin, resistive shallow layer 40...

[1] We have used magnetotelluric data imaging to determine the resistivity structure across southern Kenya and our results suggest the presence of a buckled blocky or segmented lithosphere across the region. Prominent steep conductive zones at the Oloololo (OLO) escarpment and eastern rift margin allow us to subdivide the region into three crustal domains. West of OLO, a bow-shaped conductor un...

Abstract Recent experiments on Nb-doped SrTiO 3 have shown that the superconducting energy gap to transition temperature ratio maintains Bardeen–Cooper–Schrieffer (BCS) value throughout its dome. Motivated by these and related studies, we show Cooper pairing mediated a single soft transverse-optical phonon is most natural mechanism for such dome given experimental constraints, present microscop...

To Professor Arnulf Schlüter on his 60th Birthday The dynamic evolution and the saturated state of a long sheet pinch subject to growth of resistive tearing modes was investigated by numerical solution of the 2D MHD equations. Both the compressible and the incompressible equations were used, and the difference is found to be negligible. The necessity of considering a resistive equilibrium is st...

The NIMROD and M3D / M3D-C codes now each have both a resistive MHD and a two-fluid (2F) capability including gyroviscosity and Hall terms. We describe: (1) a nonlinear 3D verification test in the resistive MHD regime in which the two codes are in detailed agreement , (2) new studies that illuminate the effect of two-fluid physics on spontaneous rotation in tokamaks, (3) studies of nonlinear re...
