The United States Environmental Protection Agency (EPA) requires the determination of important trace elements in a variety of environmental samples. Graphite furnace atomic absorption methods are recommended for some elements including As, Se, Cd, Pb, Tl, Sb, Ag, Be and Cr. Graphite furnace analyses can be difficult due to chemical and spectral interferences. Quantification in atomic absorptio...

Let Xi, i ∈ N, be independent and identically distributed random variables with values in N0. We transform (‘prune’) the sequence {X1, . . . , Xn}, n ∈ N, of discrete random samples into a sequence {0, 1, 2, . . . , Yn}, n ∈ N, of contiguous random sets by replacing Xn+1 with Yn + 1 if Xn+1 > Yn. We consider the asymptotic behaviour of Yn as n → ∞. Applications include path growth in digital se...
