Sentence examples for dummy gradient from inspiring English sources
The first 4 s of the functional run consisted of "dummy" gradient and radio frequency pulses to allow for steady state magnetization during which no stimuli were presented and no fMRI data collected.
Indicator dummy variables were used to evaluate the distance gradient (reference level > 200 m), the number of roadways near residence (zero as reference level), and the two traffic density approaches (the lowest density levels as reference levels).
In this paper, a new linear programming formulation for dummy fill synthesis is proposed, which takes more consideration to the density gradient besides the pattern density.
Specifically, IVIM imaging was based on a single-shot, twice-refocused, spin-echo echo-planar readout (TR = 2 s, TE = 100 ms, 12 repetitions after a dummy scan, diffusion time = 42 ms, ratio of diffusion time to gradient duration ~ 1).
The fMRI runs comprised 2 dummy scans followed by 600 whole-brain scans using single-shot gradient-refocused echo-planar imaging (EPI) (TR = 2.0 s, TE = 25 ms, flip angle = 90°, 36 slices).
We also performed a seed-dummy experiment to investigate the role of earthworms as secondary seed dispersers along a plant diversity gradient.
Imperceptibly the gradient increased.
