Modern LED lights come with big promises: they'll save energy, include smart features and last for years without burning out. But in reality, that last part doesn't always hold up. After testing and ...

Due to their high density, scalability, and low-power properties, 1-transistor-1-resistor (1T1R) RRAM-based crossbars have been exploited in the past. However, the series resistance of the transistor ...

Logic elements “Exclusive OR” are widely used in a variety of digital devices. However, in some cases, for example, when using increased operating voltages, the use of standard chips is impossible.

Magnetoencephalography (MEG) based on optically pumped magnetometers (OPM-MEG) has shown better flexibility in sensor configuration compared with the conventional superconducting quantum interference ...

In an article in the August 2011 Model Railroader, I described a method to control yard ladders with a single rotary switch. By simply turning the rotary switch, all turnouts would automatically line ...
