Perhaps the prize for the season's most unexpected highlight, however, is a pair of muscular nude bacchants riding panthers--a reduced version of the enigmatic but spectacular bronzes, formerly in the Rothschild collection, that have been attributed to everyone from Sansovino to Tetrode and, most recently, Michelangelo.
Due to that the distance between four wires in the recording tetrodes was about 15~25 [micro]m; LFP signals recorded by the wires of a tetrode were highly similar.
They suppose that the energy of particles is given by a time-symmetrical field; this interpretation was made by Tetrode and assumes that particles are not self-interacting.
This structure based tunnel diode shows great promise as an oscillator and high-frequency threshold (trigger) device since it can be operated at frequencies far greater than the tetrode would, well into the microwave bands.
(2) The microelectrode used in this study was multielectrode arrays rather than tetrode. Due to the dense distribution of neurons in hippocampus, it is hard to cleanly sort signals recorded from one single electrode into single units.
In addition, LFPs recorded from 4 channels of a tetrode were highly similar since the distance between wires in a tetrode was only about 15-25 [micro]m.
As described by Wayne Tustin, principal at Equipment Reliability Institute and a long-time EE contributor of vibration testing articles, the image accompanying this article shows a Ling water-cooled vacuum tetrode power amplifier to the left of the shaker.
Ideal for MIL-STD-461/462, RS103 testing, this tetrode tube RF amplifier provides power output of 1000 Watts.

Gerhard, a native of Hertogenbosch, was among a remarkable group of Netherlandish sculptors, including Giambologna, Willem Tetrode, Johann Gregor van der Schardt, Hans Mont, and Adriaen de Vries, who moved to Italy and pursued careers abroad.
They discussed this with Einstein, who suggested a proposal by Tetrode that light was a two-way communication exchange between source and receiver utilizing in- and out-waves.
