The trigger system for the ALICE Dimuon Arm will be based on Resistive Plate Chambers. A RPC prototype, with electrodes made of low resistivity bakelite (ρ ∼ 3·109Ωcm) has been tested both at the SPS and at the GIF. The results for operation in streamer mode are presented here.

We study the three-dimensional XY-spin glass as a model for the resistive behavior of granular superconductors containing a random distribution of π junctions, as in high-Tc superconducting materials with d-wave symmetry. The π junctions leads to quenched in circulating currents (chiralities) and to a chiral-glass state at low temperatures, even in the absence of an external magnetic field. Dyn...

The paper describes a new upwind conservative numerical scheme for special relativistic resistive magnetohydrodynamics with scalar resistivity. The magnetic field is kept approximately divergence free and the divergence of the electric field consistent with the electric charge distribution via the method of Generalized Lagrange Multiplier. The hyperbolic fluxes are computed using the HLL prescr...

The design process of a superconducting current limiter (SFCL) requires simulation and definition of its electrical, magnetic and thermal properties in form of equivalent circuits and mathematical models. However, any change in SFCL parameters: dimension, resistance, and operating temperature can affect the limiting mode, quench time, and restore time. In this paper, following the simulation of...

The electric capacity of various tissues surrounding the heart has been investigated in living dogs, using frequency ranges from 10 to 10,000 c.p.s. Electrode polarization, a serious source of error in such measurements, has been corrected for. Discussion of our results and of resistivity data previously obtained in body tissues proves that the electric properties of body tissues are primarily ...

Measurements of temperature-dependent in-plane resistivity ρ(T) were used to determine the upper critical field and its anisotropy in high-quality single crystals of the stoichiometric iron arsenide superconductor KFe2As2. The crystals were characterized by the residual resistivity ratio ρ(300 K)/ρ(0) up to 3000 and the resistive transition midpoint temperature Tc=3.8 K, significantly higher th...

This work aims at figuring out the spatial relationships between the geophysical and geological models in a case study pertaining to copper-sulfide mineralization through an integrated 3D analysis of favorable target. The Ghalandar Skarn-Porphyry Cu Deposit, which is located in NW Iran, is selected for this research work. Three geophysical surveys of direct current electrical resistivity and in...

A spin density-wave quantum critical point (QCP) is the central organizing principle of organic, iron-pnictide, heavy-fermion and electron-doped cuprate superconductors. It accounts for the superconducting Tc dome, the non-Fermi-liquid resistivity, and the Fermi-surface reconstruction. Outside the magnetically ordered phase above the QCP, scattering and pairing decrease in parallel as the syste...
