The experimental control was a flat cross-correlation after unit firing shuffling.
In contrast, cells that prefer lateral headings generally have monotonic tuning curves around straight ahead (e.g., Figure 4 figure supplement 2E), and this generally yields rather flat cross-correlation functions with no clear peak (e.g., Figure 4 figure supplement 2F).
It might be also worth mentioning that positive IBD correlations largely outnumbered flat or negative correlations (significance not considered here) in the literature; a trend which might have some biological meaning.
The simulation predicts that the enhancement of the asymptotic values of the mass-transfer coefficients above those predicted by conventional flat-plate correlations is due to the effects of the gaps between the boards in generating additional turbulence throughout the array of boards.
The final T1 or ΔT1 was unrelated to cell density, or indeed the total number of cells, with flat lines of correlation and wide scatter (results not shown).
This is consistent with a flat 3D linear correlation that is observed when connecting the respective data (as shown by the black plane on the graphs in Fig. 3).
Then, the effect of space-time (ST) code on the performance of multiple-input multiple-output (MIMO) systems was studied over flat-fading spatial correlation channels in [5, 6].
These sequences exhibit some useful properties: (i) cyclically shifted versions of themselves are orthogonal to each other, (ii) constant amplitude, (iii) zero auto-correlation, (iv) flat frequency domain response, and (v) cross-correlation between two ZC sequences is low [25].
First flat minimum of 1D correlation function was used to determine the value of crystallinity (ΦL).
Note that the residual spectrum of the final solution in Figure 2 is almost flat and the residual correlation resembles white noise.
