In this paper, we will discuss the concept of almost sure convergence for specic groups of fuzzyrandom variables. For this purpose, we use the type of generalized Chebyshev inequalities.Moreover, we show the concept of almost sure convergence of weighted average pairwise NQDof fuzzy random variables.

Most studies of virulence of infection focus on pairwise host-parasite interactions. However, hosts are almost universally co-infected by several parasite strains and/or genotypes of the same or different species. While theory predicts that co-infection favours more virulent parasite genotypes through intensified competition for host resources, knowledge of the effects of genotype by genotype (...

We investigate the statistics of the number N(R, S) of lattice points, n E Z-', in an annular domain /7(R, w) = (R + w)A\RA, where R, w > 0. Here A is a fixed convex set with smooth boundary and w is chosen so that the area of/7(R, w) is S. The statistics comes from R being taken as random (with a smooth density) in some interval [c~ T, c, T], c2 > ct > 0. We find that in the limit T--* oo the ...
