In the experiment, the rotation is halted at more than 22 μm/s (data not shown).
This precession of the experiment's rotation axis drives the spin-over mode, which can be understood as the fluid spinning in a state of solid-body rotation but with an axis that lags that of the experiment itself.
Finally, at the end of the dense array experiment, the rotation sensor was installed in co-location with a translation accelerometer, again in the Koutavos basin, 140 m from the first location of phase 1, at the location for the future permanent vertical array; this was operated from March 11 , 2014 to July 2, 2015 (i.e., for around 16 months).
In the first control experiment, the rotation direction of grating was changed from clockwise to counter-clockwise.
In some experiments the rotation occurred in several steps, i.e., the hot zone halted at one or more locations before completing one cycle of rotation.
These experiments include rotation scans determining the focal full width half maximum (FWHM), transmission measurements, test of different collimator lamellas and performance tests of the cooling of the filter.
We verify by experiments the rotation invariance and show that we are capable of computing much higher order of Gaussian–Hermite invariants than of geometric invariants, which brings better discrimination power.
In a staircase design similar to the aftereffect experiments, real rotation and or curvature motion was added to the adaptor stimulus in order to bring their percept of any motion to zero ("dynamic nulling").
We have previously demonstrated in animal experiments that rotation of an inserted ultra-fine acupuncture needle will cause winding and gathering of collagen fibers from the periphery toward the needle, and therefore can be used to achieve highly specific mechanical perturbations of fibrous connective tissue [ 52- 54].
