It is well known that the set of values a lower central word in group G need not be subgroup. For fixed ?r and for p ? 5, Guralnick showed if finite p-group such verbal subgroup ?r(G) abelian 2-generator, then consists only ?r-values. In this paper we extend result, showing assumption can dropped. Moreover, show result remains true even p= 3. Finally, prove analogous pro-p groups true.

The most reliable way to align two proteins of unknown structure is through sequence-profile and profile-profile alignment methods. If the structure for one of the two is known, fold recognition methods outperform purely sequence-based alignments. Here, we introduced a novel method that aligns generalised sequence and predicted structure profiles. Using predicted 1D structure (secondary structu...
