寿命效率并不总是随着耗散率的增加而增加

Life efficiency does not always increase with the dissipation rate

Marco Baiesi, Christian Maes

摘要:

重要的生命支持性质与熵产生率之间不存在普遍的正相关关系。简单的原因是,非耗散和时间对称的动力学方面也与建立最佳功能有关。事实上,这些方面甚至在平衡周围的非线性机制中也是至关重要的,我们在介观尺度上发现了生物处理。我们通过分子马达、昼夜节律周期和感觉适应的例子来具体说明这些主张,这些马达在某些情况下的性能确实会因耗散功率的增加而受到破坏。我们使用耗散和时间反演破坏量之间的关系,以保持定量的讨论,也在有效的模型中,物理熵的产生是不清楚地识别。

英文摘要:

There does not exist a general positive correlation between important life-supporting properties and the entropy production rate. The simple reason is that nondissipative and time-symmetric kinetic aspects are also relevant for establishing optimal functioning. In fact those aspects are even crucial in the nonlinear regimes around equilibrium where we find biological processing on mesoscopic scales. We make these claims specific via examples of molecular motors, of circadian cycles and of sensory adaptation, whose performance in some regimes is indeed spoiled by increasing the dissipated power. We use the relation between dissipation and the amount of time-reversal breaking to keep the discussion quantitative also in effective models where the physical entropy production is not clearly identifiable.
