Taking the logarithm of both sides of the equation leads to an alternative formulation of the Hill equation:
The function H(p(t - T)) is generally a Hill equation representing the rate of delayed production of mRNA, where the delay, T, is assumed to be a positive constant.
The waveguide is modelled as a uniform elastic string periodically supported by a discontinuous Winkler elastic foundation and, as a result, a Hill equation is found.
This work focuses on assessment of the Hill equation's ability to predict the process of spontaneous imbibition of a porous material with "oil-in-water" emulsions and to compare its adequacy with both the classical and modified Washburn equation.
We used a dose-response curve fitted to a Hill equation, y = [([A.sub.1] - [A.sub.2])/(1 + (x/C)[n.sub.H])] + [A.sub.2], in which [A.sub.1] represents 0 tail current inhibition, [A.sub.2] represents 100% inhibition, C represents the [IC.sub.50] concentration, and [n.sub.H] represents the Hill slope.
Data are fitted with the Hill equation: Percent increase = maximum increase/{1 + [([EC.sub.50]/[BPA]).sup.Hill coefficient]}, where maximum increase = 209.7%, [EC.sub.50] = 0.814 nM, and Hill coefficient = 0.34.
When phosphorylation and dephosphorylation of p53 are considered separately, a near-optimal switch is possible via Hill equation, where the Hill coefficient equals the number of phosphorylation sites [24].
[15] discussed four kinds of formation designs based on Hill equation and analyzed their stability under various perturbations.
Although proposed almost a century ago, the Hill equation [1] continues to be popular and useful in describing complex biochemical and metabolic reactions.
Although the "Capitol Hill equation gets a lot simpler" under such a proposal, the debate within the industry would increase, creating more conflict that could confuse the issue.
In the absence of sex differences, the Hill equation reduces to a more general form of (2),
