Several recent reports (Mayshar et al., 2010; Laurent et al., 2011; Lister et al., 2011; Gore et al., 2011; Hussein et al., 2011) uncover genetic and epigenetic alterations in induced pluripotent stem cells, stimulating debate about their future. However, will these important findings really impact what we hope to gain?

In this paper we study the propagation of acoustic waves in a one-dimensional medium with a short range correlated elasticity distribution. In order to generate local correlations we consider a disordered binary distribution in which the effective elastic constants can take on only two values, η(A) and η(B). We add an additional constraint that the η(A) values appear only in finite segments of length n.
