Before revision:  index \beta, causing a bifurcation for the likelihood of transcription at the critical non-Gaussianity index value \alpha=1 (i.e., beyond which the likelihood for transcription suddenly increases ), and achieving a turning point at the threshold value \beta \approx 0.55 (i.e., beyond which the likelihood for transcription  reversed for \alpha values).
