An alternating permutation of length n is a permutation π = π1π2 · · ·πn such that π1 < π2 > π3 < π4 > · · · . Let An denote the set of alternating permutations of {1, 2, . . . , n}, and let An(σ) be the set of alternating permutations in An that avoid a pattern σ. Recently, Lewis used generating trees to enumerate A2n(1234), A2n(2143) and A2n+1(2143), and he posed some conjectures on the Wilf-...

The aim of this observational, population-based study was to compare subjective health complaints (SHC) in Norwegians, living in a Western welfare society, and Maasai people, living in rural Kenya under primitive conditions. An interview-based version of SHC inventory was used. Data from 320 Maasais were compared to data from 1243 Norwegians. The Maasais had significantly higher score than the ...

The ionization potentials and electron affinities of thymine, cytosine, adenine, guanine, and uracil were determined at density functional level using different exchange-correlation functionals and basis sets. Results showed that the computed ionization potentials are very close to the experimental counterparts. The sign of adiabatic electron affinities of adenine, thymine, and uracil is unaffe...
