It was late Sunday evening, and we were still trying to trace why the embedded DSL modem was feeding a strange 50-MHz carrier into the network—much stronger than –40-dB noise allows. And no 50-MHz ...

The vast majority of bearing failures in electric motors and electric motor-driven equipment are due to mechanical and thermal causes. However, currents that flow through induction motor bearings can ...

An international research team have observed “orbital pumping,” a new phenomenon in which orbital currents are generated from the precession of magnetization in magnetic materials. Microwave-induced ...

Physicists from Trinity College Dublin and the Universidad Complutense of Madrid have made a peculiar discovery in which energy moves from a colder to a hotter region. They describe how a quantum ...
