Longitudinal nerve movement was measured using frame-by-frame cross-correlation analysis from high frequency ultrasound images during individual components of slumped sitting.
White blood cell displacement through the capillaries creates an observable artifact among red blood cells; the velocity of this artifact can be measured using time-frame analysis, as previously reported.
The velocity fields were measured using the two-frame PTV method in a circulating water channel.
The flow field was measured using the two-frame cross-correlation technique.
The velocity fields were measured using the two-frame cross-correlation technique.
The velocity field around the prism model and surface pressures were measured using the single-frame double-exposure particle image velocimetry system and an electronic pressure scanner, respectively.
The instantaneous velocity field around the fence and prism model was measured using a two-frame Particle Tracking Velocimetry (PTV) technique.
Msn2-mCherry nuclear localization was measured using a 5-frame z-stack series of 0, ±1.2 μm, ± 2.4 μm above and below the focal plane using a 500 ms exposure time and imaging every 10 min. Msn2-mCherry fluorescence was corrected for photobleaching.
Exposure to stress or worry was measured using a lifetime time frame.
Waggle-phase duration was measured using units of video frames and thus calculated by multiplying the number of frame units by 1/30 s.
