The design of neural hardware is informed by the prominence of differentiated processing and information integration in cognitive systems. The central role of

Elementary Again

Author(s)
Mark W. Keller
Mark Keller explains how the elementary charge will soon be reinstated in metrology - and why it got sidelined in the first place.

A new magnet design for future Kibble balances

Author(s)
Stephan Schlamminger, Shisong Li, Michael Stock
We propose a new permanent magnet system for Kibble balance experiments, which combines advantages of the magnet designs invented by the National Physical
