Complex systems such as ecosystems, the climate and stock markets produce emergent behaviour which is capable of undergoing dramatic change when pushed beyond a tipping point. Such complex systems display Early Warning Signals in their behaviour when they are close to a tipping point. Here we show that a complex chemical reaction network can also display early warning signals when it is in close proximity to the boundary between oscillatory and steady state concentration behaviours. We identify early warning signals using both an active sensing method, based on the recovery time of an oscillatory response after a perturbation in temperature, and a passive sensing method, based upon a change in the shape of the oscillations. The presence of the early warning signals indicates that complex, dissipative chemical networks can intrinsically sense their proximity to a boundary between behaviours.

化学反应网络中的预警信号。
诸如生态系统，气候和股票市场之类的复杂系统会产生新的行为，当超出临界点时，它们会发生巨大的变化。这种复杂的系统在接近临界点时会在其行为中显示预警信号。在这里，我们表明，当复杂的化学反应网络靠近振荡浓度和稳态浓度行为之间的边界时，它也可以显示预警信号。我们使用基于温度波动后振荡响应恢复时间的主动感应方法和基于振荡形状变化的被动感应方法来识别预警信号。预警信号的存在表明复杂，
