Profiles are generated by regularly sampling the current registers on each CPU and converting the runtime PC value into something meaningful to the programmer.
The cumulative flow across all pores in the system is monitored electrically by sampling the ionic current across the chip using an Axon Axopatch 200B patch-clamp amplifier.
The current control signals ca, cb and cc are obtained by sampling the grid side currents ia, ib and ic as the input of the inner current controller.
The chart, generated by Dr. Marcus Feldman of Stanford and colleagues and published in the current Science, was made by sampling the DNA of 1,056 people from 52 of the many populations around the world.
Again, FPGA can accumulate energy consumption by sampling power supply current at 10M SPS (samples per second).
This is most likely the case for rare transcripts or those showing temporal, spatial, or alternative forms of regulation that is not captured in the conditions sampled by the current EST libraries.
The electrical characterization is made using a custom-built, LabVIEW-controlled measurement set-up, where the voltage is controlled by a 16-bit National Instruments DAQ card, which also samples the current measured by a Stanford Research SR 570 current amplifier.
By rapidly flash freezing tissue samples, the current study was designed to minimise changes in phosphorylation whereas Balsara et al (2004) used archival paraffin-embedded samples that may not have been subject to such handling.
At each step of the gradient descent, we had to sample a set of sequences by Gibbs sampling, under the current values of the parameters, so as to numerically estimate the gradient of the log-likelihood.
This method samples the current response triggered by a potentiostatic step (typically 50 mV or so in an amplitude) at a frequency of 50 kHz with a possibility to extract a value of capacitance of the layer.
