Genes sorted by relative correlation with |γ₁〉_N and |γ₂〉_N of normalized elutriation. (a) Normalized elutriation expression of the sorted 5,981 genes in the 14 arrays, showing traveling wave of expression. (b) Eigenarrays expression; the expression of |α₁〉_N and |α₂〉_N, the eigenarrays corresponding to |γ₁〉_N and |γ₂〉_N, displays the sorting. (c) Expression levels of |α₁〉_N (red) and |α₂〉_N (green) fit normalized sine and cosine functions of period Z ≡ N − 1 = 5,980 and phase θ ≈ 2π/13 (blue), respectively.
