The influence of the electric field dependence of the differential conductivity on superconducting state stability in multifilamentary superconducting composites is studied theoretically. The obtained stability criterion allows one to determine the upper limit of the values of transport current and background electric field in the superconductor. To illustrate the theory, the superconducting st...

Electric current-induced phase alternations have been imaged by fast magnetic resonance image (MRI) technology. We measured the magnetic resonance phase images induced by pulsed current stimulation from a phantom and detected its sensitivity. The pulsed current-induced phase image demonstrated the feasibility to detect phase changes of the proton magnetic resonance signal that could mimic neuro...

Evidence is presented which indicates that, notwithstanding the change in sign made by Sommerfeld in his 1926 paper on radio wave propagation, the radiation field of a vertical electric dipole may be separated into space and surface wave components. Sommerfeld's original concepts as to the characteristics of two such waves in radio transmission are largely substantiated. It is shown that a spac...

Electrocution is not an uncommon cause of death. A case of fatal electrocution by a metal wire that was used as a support for the insulated television cable wire is reported. Electric current flowed through the metal wire when it touched the residential power line. Electrical injury caused because of contact with the live metal wire is described with histopathological findings. This case report...

We performed a ultra—short width high voltage pulse electrolysis using a thin Pd wire cathode; a diluted electrolytic solution of D2O+LiOD was used in a peculiar wire—turned electrodes geometry. The deuterated Pd loading was evaluated by the D/Pd normalised electric resistance curve (R/Ro). After a long time of electrolysis a very high D/Pd loading (1:1 or more) was reached. Very low R/Ro (< 0....

This Letter presents an accurate and stable method for the solution of transient electromagnetic response from conducting wire structures with the use of the time-domain electric-field integral equation (TD-EFIE). By using an implicit scheme with the central finite difference for the TD-EFIE, the transient responses from a wire scatterer illuminated by a plane wave and a wire antenna with an im...

Terahertz (THz) pulses are applied in areas as diverse as materials science, communication and biosensing. Techniques for subwavelength concentration of THz pulses give access to a rapidly growing range of spatial scales and field intensities. Here we experimentally demonstrate a method to generate intense THz pulses on a metal wire, thereby introducing the possibility of wave-guiding and focus...

We present the opinion of some authors who believe there is no force between a stationary charge and a stationary resistive wire carrying a constant current. We show that this force is different from zero and present its main components: the force due to the charges induced in the wire by the test charge and a force proportional to the current in the resistive wire. We also discuss briefly a co...

This paper presents the design of neural networks compared with the conventional technique, a hysteresis controller for active power filter for three-phase four-wire electric system. A particular three-layer neural network structure is studied in some detail. Simulation and experimental results of the active power filter with both controllers are also presented to verify the feasibility of such...
