Enhanced sensitivity current density imaging
Journal of Magnetic Resonance, 2010One of the major weaknesses of current density imaging (CDI) is its poor sensitivity and therefore a need for the use of high voltage in CDI. In this work, a new CDI technique with enhanced sensitivity (ES-CDI) is presented. The ES-CDI sequence overcomes the sensitivity problem in samples with a long T(2) relaxation time that allows the use of a long ...

Current density in HTSC current leads
Russian Electrical Engineering, 2016The thermal state of high-temperature superconductor current leads is considered upon changes in the current density. A change of the thermal regime in the resistive section and at a point of contact between a normal conductor and superconductor is described. The factors limiting the current density in current leads are revealed.

The current density in quantum electrodynamics
Il Nuovo Cimento, 1952The formulation of field theory given previously suggests an alternative expression for the current density in quantum electrodynamics. This expression is gauge-invariant and conserved and differs from the usual current density by the divergence of a tensor which vanishes in the absence of a field. Corresponding to this current is a new electromagnetic
