The replacement of the disappearing incandescent lamps will be realized at a significant scale by compact fluorescent lamps (CFLs). Light regulation is a popular feature that is easily provided by incandescent lamps using a simple electronic equipment, the dimmer. Dimming can be achieved by (dimmable) CFL lamps as well, however this is done in a completely different way than in case of the form...

We report the case of a patient with Fahr disease presenting with schizophrenia-like psychosis for whom a technetium Tc99 methyl cysteinate dimmer brain study was used to evaluate regional blood flow. A brain single photon-emission CT study showed increased cerebral blood flow to the bilateral temporal lobes. Such perfusion abnormalities may reflect psychotic symptoms, including auditory halluc...

The Anderson localization is introduced as well as the scaling theory of localization. These predict the absence of the metallic state in 1 and 2 dimensions. In such a theoretical background, the random dimmer model is shown to be novel due to its ability to escape from localization. This model is also shown to be applicable to describe the insulator-metal transition in a wide range of conducti...
