The addition of a de-rotation screw to the standard DHS can offset this disadvantage, but this configuration still lacks a stable-angle configuration [6, 7] .
Stable contact angle of water on NCP-based substrate as compared to that of pure NCP implies that a protective layer of acrylic resin has been successfully formed on the surface of NCP and water cannot permeate into inner NCP, exhibiting excellent waterproof capacity.
Fifth, after the Butterworth low-pass filtering, we obtain a stable heading angle for each step.
By contrast, the sample with modification shows a stable contact angle (Figure 2d,e,f).
With the development of the locking plates, a stable fixed angle design that works as an internal fixator was created.
Therefore, feedback control could be adopted to obtain a stable scanning angle during the operation of a microscanner.
In other words, only one thermodynamically stable contact angle exists.
A time analysis showed that the disconjugate drift during fixations is high at the beginning of fixations and negligible after about 50 to 100 ms [15], [18]; thus, the oculomotor system overcomes asymmetric pulse-step mismatches first during fixations, whereas after a certain time window such mismatches are resolved and the eyes reach an approximately stable vergence angle.
True entrainment is characterized by a stable phase angle difference between two synchronized rhythms.
The bridged dipodal silane, 1,10-bis trimethoxysilyl decane, which appeared to maintain a relatively stable contact angle over time in the first part of the experiment, began to exhibit greater hysteresis and a mottled appearance, with hysteresis exceeding 30° after 1,10-bis trimethoxysilyl decane
