From: An oscillating reaction network with an exact closed form solution in the time domain
Two species harmonic oscillator (2SHO). Reaction network that creates oscillations in the chemical species \(S_1, S_2\). The reaction network is designed so that its time domain solution is a system of linear differential equations. The text describes constraints on the kinetic constants (\(k_i\)) and initial conditions of the chemical species to create an oscillator such that species concentrations are non-negative, a requirement for biological feasibility
