Main outcome measures: The primary outcome measure was the frequency of AEs.
2
The principle was quickly adapted for medium-frequency use in American civil aviation.
3
Controls were frequency-matched to cases by birth year, sex, and study site.
4
The Italian EPIC food frequency questionnaire was used to determine food intake.
5
All of the studies used food frequency questionnaires to assess participants' diets.
Ús de temporal frequency en anglès
1
The degree of elongation decreased as temporalfrequency increased.
2
Drifting gratings can modulate the activity of visual neurons at the temporalfrequency of the stimulus.
3
Orientation was variable between cells and temporalfrequency dependent, and a frequency-doubled component was evoked by chromatic modulation.
4
The present study is the first to measure the magnitude of grating induction as a function of temporalfrequency.
5
Motion phase discriminations were similar to motion detection and were robust over increases in spatial separation and temporalfrequency, but not so for stationary oscillations.
6
Temporalfrequency did not have a large effect on the ratio of rod to L-cone signal strength.
7
We conclude that the visuomotor pathways for pursuit are capable of processing image motion at high temporalfrequencies.
8
Flash and pattern visual evoked potentials (VEPs) to two temporalfrequencies of stimulation were studied in nineteen rats.
9
We interpret the age-related decline in grating induction magnitude at 4 Hz to reflect a diminished capacity for inhibitory processing at higher temporalfrequencies.
10
They were then anesthetized using urethane, and electrophysiological techniques were used to examine neuronal responses to different orientations, spatial and temporalfrequencies, and contrast levels.
11
Spatial frequencies ranged from 0.25 cpd up to the resolution limit, temporalfrequencies from 0.1 Hz up to the CFF.
