While only some of the potential organizations have been observed, others may also exist, except that their populations may be too low to be observed by experiment.
It is crucial for allowing us to make sense of the Universe, but has never been observed by experiments.
However, transitions from excitons with finite L were observed by experiments in both ZnSeTe and SiGe [4, 5].
It was found that the separation PH/PNP factor attaining 50 was observed by experiments and calculations.
Though jump-to-contact have also been observed by experiments [7, 12, 29] and MD simulation [17], our research further reveals that the strong localized attractive force (about 2.8 GPa) between large Ni tip and Cu substrate during jump-to-contact can lead to plastic deformation of Cu substrate.
Recently, three different models of Zn2+ binding to Aβ were observed by experiments: First, the NMR structures of Zn2+−Aβ1−16 in aqueous solution at pH 6.5 and 7.4 showed that Zn2+ is bound to these three histidines and to the two carboxylic groups of Glu11.
The relationships between propagation speed ν and the number of nodes in the linear structure under different proportions are observed by experiment as shown in Figure 8a.
The relationships between propagation speed ν and the number of nodes n in the ring structure under different proportions are observed by experiment as shown in Figure 9a.
Whilst the minimum Ca O distance for the interlayer Ca atom in the 11 Å model is rather short (2.203 Å), it is not shorter than the minimum distance that has been observed by experiment in calcium silicate hydrates in general (§5.1) and it is in fact very similar to the minimum in Merlino et al.'s structure (2.236 Å).
The purpose of this paper is twofold: firstly to demonstrate unequivocally the ordered distributions that are possible, and secondly to use the results of that demonstration to provide a plausible explanation for the variation in the lower value of x that has been observed by experiment.
