Increasing the NA was found to cause a slight shift of the sampling volume towards lower z values (data not shown).
Since any shift of the sampled spectral interference signal in time results in a spectral shift δk, using the Fourier shift theorem, the resulting phase difference between subsequent axial scans is given by ΔΦ trig = 2π·δ k·z.
There will also be undesirable motion on much slower timescales, which may occur due to slight shifting of the sample within the chamber, as an artefact of the z scanning process (as discussed in detail in the next section), or ultimately even due to growth of the embryo.
Figure 1 PL emission from the investigated sample at T = 100 K. Figure 2 The s-shape PL shift of the investigated sample.
The frequency of the embedded aluminum wire sample remained relatively constant at low and high temperatures, leading to the conclusion that the frequency shift of the SMA sample was a result of the shape memory effect.
When conducting inference for nested models, it is important to control for an existing upward shift of the predicted sample errors.
The threshold voltage shift of the reference sample comes from the charge trapping sites existing in the interface between the channel layer and control oxide layer or in the sputtered SiO2 layers.
In comparison, only 30 genes acquired a more root-like expression upon cytokinin treatment of shoots and no shift of the respective sample towards root-like expression was observed in the PCA.
Third, it does not need a precise location or precise shifting distance of the sample inside the waveguide.
