Tdim Ionospheric Model Tec, Hmf2, And Nmf2 At Mid-Latitude Northern Hemisphere, Used In The Paper Titled "Is Tec A Viable Servo Input?", Jan J. Sojka

The externally imposed vertical drift in the F region is an extremely important driver of ionospheric dynamics but is very difficult to measure or map. Ionospheric servo algorithms have used hmF2 as F-region observable to infer the vertical drift. However, an even more plentiful observable is the total electron content (TEC) whose coverage over northern mid-latitudes has both spatial and temporal availability that matches those of the probable mechanisms responsible for vertical drift dynamics.

This ionospheric, first principle physics, study shows that TEC is a viable servo parameter at mid-latitudes in the noon sector. The servo relationship is shown to …

Data For: Vestibular Attenuation To Random-Waveform Galvanic Vestibular Stimulation During Standing And Treadmill Walking, Chris Dakin

The ability to move and maintain posture in space is critically dependent on motion and orientation information provided by the vestibular system. When this system delivers noisy or erred information it can, in some cases, be disregarded through habituation. Here we investigate whether multiple mechanisms of habituation act to attenuate vestibulomotor gain due to noise added using random-waveform electric vestibular stimulation (EVS). Forty-five participants completed one of three conditions. Each condition consisted of two four-minute standing periods with stimulation surrounding a one-hour period of either walking with stimulation, walking without stimulation, or sitting quietly. Participants stood and walked on an …
