216405-1 Large charge disproportionation has been confirmed in the metallic state of a 1=4-filled organic conductor BEDT-TTF 2RbZn SCN 4 by means of 13C-NMR analysis on a selectively 13C-enriched single crystal sample. By comparing the homogeneous and inhomogeneous linewidths, the temperature dependence of the extremely slow dynamics of charge fluctuations has been determined first. The exotic ...

Harmonic current pollution is a one of the major power quality problem in electrical power systems. In office buildings one of the main harmonic sources is a large numbers of computer loads. Especially, personal computers apply harmonic distortions to their power supply systems. In this study, harmonics models of equipments, a MATLAB ® code and single-phase Simulink simulation models are develo...

We study the reproducible conductance fluctuations seen between the quantum Hall plateaus in the conductance of two-terminal submicron silicon MOSFETs. For the dramatic fluctuations at the insulator-to-first-plateau transition we find a conductance distribution that is flat between zero and e/h. We point out that this is consistent with the prediction of random matrix theory for a conductor wit...

We investigate the effect of weak interactions on the full counting statistics of charge transfer through an arbitrary mesoscopic conductor. We show that the main effect can be incorporated into an energy dependence of the transmission eigenvalues and study this dependence in a nonperturbative approach. An unexpected result is that all mesoscopic conductors behave at low energies such as either...

Audible noise generated from water drops collected on the transmission line conductor surface during foul weather is a major concern in UHV (ultrahigh voltage) transmission line design. Although the noise can be kept to an acceptable level by maintaining a surface electric gradient below 15 to 17 kV/cm, this alternative is quite costly since it would mean having larger conductor bundles and hen...

Physarum polycephalum is a macroscopic single celled plasmodial slime mould. We employ plasmodial phototactic responses to construct laboratory prototypes of NOT and NAND logical gates with electrical inputs/outputs and optical coupling; the slime mould plays dual roles of computing device and electrical conductor. Slime mould logical gates are fault tolerant and resettable. The results present...

We demonstrate the feasibility of using novel, small energy harvesters to power atmospheric sensors and radios simply attached to a single conductor of existing overhead power distribution lines. We demonstrate the ability to harvest the required power for operating multiple atmospheric and power-system sensors, together with short-range radios that could broadcast atmospheric sensor data to th...
