We estimated the cumulative breast dose as an approximation of breast dose in units of Gy.
The diffusion approximation is obtained by measuring time in units of N generations and letting N → ∞ under the assumption that s, α, β = O(N−1).
Under this model, if tD is small, then tD measured in units of 2 NA generations is related to the population differentiation statistic Fst through the approximation tD ≈ −log(1 − Fst) ≈ Fst (Cavalli-Sforza 1969; Reynolds et al. 1983).

The huge strains that Ni Mn Ga magnetic shape memory alloys can achieve are usually described in a tetragonal unit cell approximation of a five-layered modulated (10 M) crystal structure.
My most recent work has been in approximation algorithms and hardness of approximation, particularly for constraint satisfaction problems.
Troubling on Saturday were the blurs of approximation in both the Mozart and the Dvorak.
In the 1990s, parallel developments in techniques for designing approximation algorithms as well as methods for proving hardness of approximation results have led to a beautiful theory.
Various simple methods of approximation will always yield the same succession of digits in the same order.
