The LSC analysis of the cell density on slides on which cells were growing revealed that the saturation density at confluence was distinctly lower compared with the control cells growing in parallel cultures, and the density was further decreasing with time of treatment with Mxt (depth of senescence; Fig. 1).
This conclusion was supported by comparisons between the variances of the larger optic flow sums obtained at 90° and at 45° (Max(Σω90°) and Max(Σω45°)): as shown by the histograms to the right of Figure 4B,D, the variance-to-the-mean ratio was distinctly lower at 45° than at 90° ( t(36) = 2.99, p<0.01 ).
Any interference with autofluorescence could be excluded since fluorescence of all tumours at 700 nm was uniform and distinctly lower than at 800 nm (Figure 7a).
On the other hand, two baseline schemes achieve the optimal downlink beamforming design of each other with lower computational complexity at the expense of distinctly lower power harvesting.
In Asia, Australia, Europe, and North America, the headache prevalence in the general population is approximately 50%; in Africa it is distinctly lower at 20% [2, 3].

The comparison of mid-1980s with mid-1970s nqx-values (Fig. 5) shows, with minor exceptions, distinctly lower probabilities of death at ages below 55 (males) and 50 (females), and essentially unchanged probabilities at older ages.
