The title refers in fact to the frequency of the note A, to which The Deutsche Kammerphilharmonie Bremen tunes all its instruments at the start of each concert. The note resonates at 443 pulses per second. Also, the word Hertz in German sounds exactly the same as the word for›hear...
Minimum lead inductance offers a low impedance to fast pulses. Small disc or multilayer ceramics, or polyester film types (lead pitch 2.5 or 5 mm), are preferred; chip capacitors are even better. The overall inductance of each connection is the sum of both lead and track inductances. Flat ...
(the most straightforward and least expensive type) would provide 1.0000 Hz of output. It might then be used to operate a tiny motor and escapement for a geared analogue clock that requires 1-second pulses, modulo 60 seconds counters, modulo 60 minutes counters, and modulo 12 or 24 counters...

This is significantly faster on my scope than hzeller's implementation by up to 10x. The software forks a thread that pulls from the PWM data and continuously pulses the rgb pins and the clock line. After each row, the Output Enable pin is driven high and the data is latched and the ...

Second, not all brain areas make for equally good targets and stimulation spreads to neighboring cortical areas depending on the individuals’ brain anatomy52. Third, there are large interindividual differences with regards to TMS- and more generally NIBS-effects on performance53,54. Apart from the...
This can be achieved with an increase of the beam intensity to 2 /spl times/ 10/sup 14/ protons per pulse that requires a 1.5-GeV superconducting linac, as a new injector and by upgrading the power supply system to allow cycling at 5 beam pulses per second. This paper describes the ...
