A human-machine interface for automatic exploration of chemical reaction networks [PDF]
Nature CommunicationsAutonomous reaction network exploration algorithms offer a systematic approach to explore mechanisms of complex chemical processes. However, the resulting reaction networks are so vast that an exploration of all potentially accessible intermediates is ...

Diffusive network connected chemical reaction networks
Systems Science & Control EngineeringA novel type of networked Chemical Reaction Network (CRN) model is proposed in this paper where the CRN subsystem nodes are connected in a bi-directional state-difference-driven way, forming a diffusive network. The diffusive connecting elements can also

Chemical reaction networks for computing logarithm. [PDF]
Synth Biol (Oxf), 2017 Abstract Living cells constantly process information from their living environment. It has recently been shown that a number of cell signaling mechanisms (e.g. G protein-coupled receptor and epidermal growth factor) can be interpreted as computing the logarithm of the ligand concentration.

Self-selection of dissipative assemblies driven by primitive chemical reaction networks [PDF]
Nature Communications, 2018 Selection and persistence of chemical non-equilibrium species is crucial for the emergence of life and the exact mechanisms remain elusive. Here the authors show that phase separation is an efficient way to control selection of chemical species when ...

Nonequilibrium Thermodynamics of Chemical Reaction Networks: Wisdom from Stochastic Thermodynamics
Physical Review X, 2016 We build a rigorous nonequilibrium thermodynamic description for open chemical reaction networks of elementary reactions. Their dynamics is described by deterministic rate equations with mass action kinetics.

Programming discrete distributions with chemical reaction networks. [PDF]
Nat Comput, 2018 We explore the range of probabilistic behaviours that can be engineered with Chemical Reaction Networks (CRNs). We show that at steady state CRNs are able to "program" any distribution with finite support in $\mathbb{N}^m$, with $m \geq 1$. Moreover, any distribution with countable infinite support can be approximated with arbitrarily small error under

Solving moment hierarchies for chemical reaction networks. [PDF]
J Phys A Math Theor, 2017 The study of Chemical Reaction Networks (CRN's) is a very active field. Earlier well-known results \cite{Feinberg:def_01:87, Anderson:product_dist:10} identify a topological quantity called deficiency, for any CRN, which, when exactly equal to zero, leads to a unique factorized steady-state for these networks.

Independent Decompositions of Chemical Reaction Networks [PDF]
Bulletin of Mathematical Biology, 2021 A chemical reaction network (CRN) is composed of reactions that can be seen as interactions among entities called species, which exist within the system. Endowed with kinetics, CRN has a corresponding set of ordinary differential equations (ODEs). In Chemical Reaction Network Theory, we are interested with connections between the structure of the CRN ...

Concordant chemical reaction networks [PDF]
Mathematical Biosciences, 2012 We describe a large class of chemical reaction networks, those endowed with a subtle structural property called concordance. We show that the class of concordant networks coincides precisely with the class of networks which, when taken with any weakly monotonic kinetics, invariably give rise to kinetic systems that are injective --- a quality that ...

Circuit Theory for Chemical Reaction Networks
Physical Review X, 2023 We lay the foundation of a circuit theory for chemical reaction networks. Chemical reactions are grouped into chemical modules solely characterized by their current-concentration characteristic—as electrical devices by their current-voltage (I-V) curve ...
