Although a few supermassive black holes have also been observed in this fashion, astronomers have only been able to record a few rotational cycles, which decreases the certainty of those black hole's rotational speeds.
In contrast to small-molecule inhibitors with few rotational bonds, conventional docking and scoring of protein-based inhibitors and their receptors have markedly lower rates of success [32].
Beyond hydrogen bonding, additional factors that guide the selection towards adenosine recognition include aromatic stacking interactions and relatively few rotational degrees of freedom.
Adenosine offers many binding opportunities: i) hydrogen bonding to its Watson-Crick edge, to its major and minor groove edges, and to its ribose hydroxyls, ii) aromatic stacking interaction potential on each face of the base, and iii) relatively few rotational degrees of freedom.
There are a lot of investigations published on fixation stability of different implant types about axial load but only few about rotational stability.
However, there remain very few datasets of rotational records, especially in comparison with the standard "translational" acceleration datasets.
While several studies report combined rotation and rotational mismatch between the femoral and tibial components after TKR [ 14, 18, 32, 41], few report clinical consequences associated with these parameters.
Unfortunately, few 2D experiments with rotational vortex data measured could be found due to the difficulty of recording the vortex characteristics.
With regard to accuracy of the rotational alignment, few studies have demonstrated an improvement with computer-assisted navigation compared with conventional methods [ 12, 13, 24].
Contrary to our expectation that CPEC cilia have 9+0 axoneme and should therefore rotate rather than beat as in the case of nodal cilia (Takeda et al., 1999), most of the motile CPEC cilia showed a planar back-and-forth motion, whereas a few of them exhibited rotational movements (Fig. 4A; supplementary material Movie 2).
