where ∑ ~n is the sum over all lattice vectors ~n = (Lxnx, Lyny, Lznz), nx,y,z ∈ N and Lx,y,z are the dimensions of the unit MD cell and ~xij = ~xj − ~xi. The “daggered” (†) summation indicates the exclusion of all pairs i = j inside the original unit MD cell (~n = ~0). Most molecular force fields provide exclusion schemes to exclude additional pairs, e.g., the so-called 1-3 exclusion excludes ...

R. A. FISHER (1930) developed a phylogenetic and statistical theory of dominance of wild type over mutants involving a selection of modifiers that shift the phenotype of the heterozygous mutant toward the wild type. The wild type has a selective advantage which also is conferred upon heterozygotes. FISHER (1 934,1935,1938) noted that many common mutations in the domestic fowl were dominant in c...
