There has been considerable prior research on the biological processes of morphogenesis and cellular differentiation, and the manner by which these processes give rise to symmetries in biological structures. Here we extend our previous work on thermal robustness and attractor density in cyclic formal Boolean dynamical systems, introducing a new form of spectral analysis on digital organisms at the cellular level. We interpret the phenomena of radial and bilateral symmetry in terms of spatial periodicities in the color sequences, as manifested by an organism while it orbits in its attractors. We provide new results on the influence of various organism properties on its emergent color symmetries—providing initial insights toward an eventual formal understanding of metamerism and Bateson’s Rule.

In this chapter we seek to: (1) derive a more rigorous estimate of the underground commercial sex economy (UCSE) in seven major US cities; and (2) provide an understanding of the structure of this underground economy. To estimate the size of the UCSE accurately, we had to produce simultaneous estimates in each city for the size of the cash-based trade in both illegal drugs and illegal firearms. Ordinarily, estimates for each of these are made singly, and often for a single locale at a single time. Our approach goes in the opposite direction. The operating assumption of the estimation process that follows is that estimates of the size of various domains of the underground economy (UE) are more accurate when comparative data across time and across different locations are taken into account, and when estimates of the size of one domain of the UE are forced to balance estimates of other domains in the UE with which they coincide.
