Oscillations show random phases, (middle).
The paper had shown that a dynamical system subject to both periodic forcing and random perturbation may show a resonance (peak in the power spectrum) which is absent when either the forcing or the perturbation is absent.
However, gene loss is neither complete nor random, and may show similar trends across taxa [ 27]; in teleost fishes, genes associated with signalling and gene regulation were enriched following gene loss [ 28], transcription factors were over-represented in rice [ 29], while A. thaliana preferentially retained signal transduction loci [ 26].
To find a proper prognostic model, contrary to using the highest number of precise parameters that describe the variability of the analyzed data presented as time series, it is of crucial importance to understand that too large adjustment of series may provide either the description of the signal itself or the random noise (that may show accidental regularity in a definite number of attempts).
However, there is strong evidence that TEs integrate in non-random genomic locations, and TEs may show signs of positive selection [ 11– 11].
This cohort is a small fraction of the total DS population, and the way parents were selected is not random, having the consequence that bias may show up.
Since unlinked genes of the same FGU may encode different enzymes or proteins of the same phenotypic effect(s), functional alleles of the same FGUs may show correlated responses to positive selection, resulting in non-random associations.
If the LWDH gene is detected correctly, it is expected that the LWDH genes may show modularity and have closer connections inside themselves than the random chosen ones.
Time series of VT and respiratory rate values during variable mechanical ventilation may show long-range correlations, which are more strictly 'biological', or simply random (noisy).
Consistent with the ROSG model, the present study may show that the original reason for the gene to be split was the stop-codon interference problem in a random sequence, and that functional sequences may have fortuitously occurred with high probability within these long non-coding introns (and intergenic sequences) subsequent to their origin in random DNA.
