Homology on semimodule-valued sheaves naturally generalizes network flows from the setting of numerical capacity constraints to other sorts of constraints (e.g. stochastic, multicommodity). In this talk, we present new work relating the algebraic structure of flows with local network properties and algebraic properties of the ground semiring.

Many neurological diseases, such as epilepsy and Parkinson's disease, present symptoms of pathological neuronal activity. Large bursts of neuronal activity or large scale synchronous oscillations may arise from changes in the dynamics of the neurons and/or how they are connected. How changes in network topology result in these pathological behaviors, as well as how do neurons refine their connections to prevent these behaviors from emerging normally, are fundamental questions in neuroscience.

Multiplicative updates multiply the parameters by
nonnegative factors. These updates are motivated by
a Maximum Entropy Principle and they are prevalent in evolutionary
processes where the parameters are for example
concentrations of species and the factors are survival rates.
The simplest such update is Bayes rule and we give
an in vitro selection algorithm for RNA strands that
implements this rule in the test tube where

A perusal of the contemporary biological literature involving high-throughput data sets reveals the generation of a vast amount of data and an enormous number of models (classifiers, clusters, networks) derived from this data via a plethora of algorithms.

Computation of limit cycles and their isochrons: Applications to biology

Recently, numerous engineers have demonstrated that genetic circuits can
be effectively modeled and analyzed utilizing methods originally
developed for electrical circuits leading to new understanding of their
behavior. If this is possible, then it may also be possible to design
synthetic genetic circuits that behave like particular electrical
circuits such as switches, oscillators, and communication networks.
Synthetic genetic circuits have the potential to help us better

Cellular information processing is carried out by complex biomolecular networks
that are able to function reliably despite environmental noise and genetic mutations.
The robustness and evolvability of biological systems is supported in part by neutral
networks and neutral spaces that allow for the preservation of phenotype despite underlying
genotypic variation. This talk will describe two such spaces. The first are sequence niches
that emerge in the process of satisfying constraints needed to avoid crosstalk among sets
