Extended information on determination of τ has been reported previously.[ 18] For electrical characterization of MDCK-I cells seeded onto the OECT, the channel current was measured upon application of a positive square-pulse gate voltage.
Gradient echo imaging uses repetitive radiofrequency pulses gated to the electrocardiogram so that cine images may be generated during a single breath-hold.
According to this model, an internal clock stage includes a pacemaker that emits pulses in time and an accumulator that receives the pulses gated by a switch during a certain time interval.
Liu et al. [206], by pulsing the gate bias using a pulse generator with a constant anode bias of 40 kV, showed a stable 0.3 mA temporal response over 15 h with an approximate pulse rise time of <5 ms.
The primary science event is not affected, since once event processing starts with the initial trigger pulse, a gate rejects further pulses until processing is complete.
Applying the time scales to (13), we have the patch contribution data vector which is the received signal for the pulse range gate, before combining to form a single stream as (14).
The duration of the light pulse was gated so as to deliver brief (<1 ms) pulses of light at each stimulation site.
Sorted cells were selected through sequential gating (see online supplementary figure S3A) based on forward scatter (FSC), side scatter (SSC), trigger pulse width, to gate out doublets, DAPI to gate out dead cells and CD31/CD45 binding to exclude haematopoietic and endothelial cells.
Pulse-width gating excluded cell doublets while dead cells were excluded by addition of PI and gating on the negative cells.
The effects of different transmit pulses, receive gates, apertures, SV depths and lateral foci were studied using a one-dimensional (1-D) beam-forming array, with a fixed lens in the elevation direction.
