Combinatorial gene regulation using auto-regulation.

As many as 59% of the transcription factors in Escherichia coli regulate the transcription rate of their own genes. This suggests that auto-regulation has one or more important functions. Here, one possible function is studied.

Resource distributions affect social learning on multiple timescales.

We study how learning is shaped by foraging opportunities and self-organizing processes and how this impacts on the effects of "copying what neighbors eat" on multiple timescales. We use an individual-based model with a rich environment, where group foragers learn what to eat. We vary foraging opportunities by changing local variation in resources, studying copying in environments with pure patches, varied patches, and uniform distributed resources.
