AAA - Applications of Ant Algorithms

Trying to work on a model that pulls from ant behavior...looking for parallels for application to fund selection (net long/short positions). A simple model for trail selection and formation in ant colonies is based on how an ant travels over or through a substrate as a function of pheromone trails, presumable laid down by predecessors (this is discussed in detail in ch.13 of Self-Organization in Biological Systems, ed. Camazine, et al, 2001). The equations I am trying to replicate are shown below (disregard matrix):

Replicating the simple probability of an ant choosing the left branch vs. the right branch, can a similar approach be applied to fund management, or even sector selection? Instead of using pheromones as the independent variables, could an analogous equation be derived based on momentum in and/or out of long/short positions? Ie., what is the probability of a new participant (fund manager) entering into a position as a function of the velocity/momentum established by predecessors in that sector? Can a signal be extracted that can let the new participant evaluate if their position is supported?

El Nino & respiratory ailments

Looking to do a study that relates El Nino years with respiratory ailments, focusing on global equatorial region between 20N&20S. Some work by Duncan et al (2003) focused on the 97/98 nino, but I want to do more detailed historical analysis.

nature as artifact

will start posting notes for forthcoming essay(s). along lines of nature as artifact...comments welcome

oil dispersion

Per this post, I've already received a couple of inquiries re: how to calculate plume dispersion as a function of the time of year.  I would actually calculate disp. characteristics in both GOM & Atl Ocean connecting with the relationship between the volume released and interaction with the loop current.

will post thoughts...suggestions welcome
