TL;DR: Cooperative phenomena, in which events at one place determine what happens at another, are best known in physics, with the phenomenon of phase transitions as a classic example as mentioned in this paper, and the classic example of cooperativity among biological macromolecules is that of the binding of oxygen by hemoglobin.
Abstract: Cooperative phenomena, in which events at one place determine what happens at another, are best known in physics, with the phenomenon of phase transitions as a classic example. Cooperative phenomena also have an important function in biology that was first defined and analyzed in a seminal paper published a quarter century ago (Monod et al. 1965). The classic example of cooperativity among biological macromolecules is that of the binding of oxygen by hemoglobin. According to simple mass action law, with the assumption that the four oxygen-binding sites on Hb are identical and independent or noninteracting: $${\text{HbO}_2 \longleftarrow \text{K}_{\text{diss}}\longrightarrow}\text{Hb} +\text{O}_2\;\text{and}\; [\text{Hb}][\text{O}_2]\: =\text{K}_{\text{diss}}[{\text{HbO}_2}]$$ (1)

TL;DR: In this paper, the free carrier absorption coefficients in n −ZnS were calculated as a function of free carrier concentration and compensation ratio at 10 μm and the results of calculations of 77 K free carrier and derivative logarithmic absorption coefficients were presented.
Abstract: Quantum theory is applied to calculate the free carrier absorption coefficients in n‐ZnS. This treatment includes all major scattering mechanisms and screening. We present the results of calculations of 77 K free carrier absorption and derivative logarithmic absorption coefficients, as a function of the free carrier concentration and compensation ratio, at 10 μm. We discuss the unambiguous determination of both free carrier concentration and compensation ratio for unknown samples.
