Instantaneous arithmetic computation via ratio-encoding in chemical reaction networks
David F. Anderson, Badal Joshi
We develop a general framework for instantaneous arithmetic computation using chemical reaction networks. Numerical values are encoded by ratios of species concentrations: an exten…
Noise Tradeoffs, Stationary Information Flow, and Structural Balance in Unit-Birth Networks
David F. Anderson
In 2019, Paulsson and collaborators conjectured that stochastic biochemical control networks have fundamental limits on how much intrinsic noise can be simultaneously suppressed ac…
Computing with reaction networks at input-independent speed: exponential and logarithmic functions
David F. Anderson, Badal Joshi, Tung D. Nguyen
The concept of \textit{input-independent computational speed} for chemistry-based analog computers was introduced in Anderson-Joshi (2025), where it was shown that arithmetic opera…
Stochastic Reaction Networks Within Interacting Compartments with Content-Dependent Fragmentation
David F. Anderson, Aidan S. Howells, Diego Rojas La Luz
Stochastic reaction networks with mass-action kinetics provide a useful framework for understanding processes -- biochemical and otherwise -- in homogeneous environments. However,…
Parametric Sensitivity Analysis for Models of Reaction Networks within Interacting Compartments
David F. Anderson, Aidan S. Howells
Models of reaction networks within interacting compartments (RNIC) are a generalization of stochastic reaction networks. It is most natural to think of the interacting compartments…
