we have evaluated the nmr shielding tensors for a:t,g:c,a:u in watson-crick, and u-quartet. we have computed nmr shielding tensors at b31yp level by using 6-31g(d) basis set. we have compute anisotropy and asymmetry in a:t,g:c,a:u and u-quartet. the nmr shielding tensors were calculated using the giao method. the natural bonding orbital analysis (nbo) were performed. nbo calculation have been ...
We show that the largest density of factor of i.i.d. independent sets on the d-regular tree is asymptotically at most (log d)/d as d → ∞. This matches the lower bound given by previous constructions. It follows that the largest independent sets given by local algorithms on random dregular graphs have the same asymptotic density. In contrast, the density of the largest independent sets on these ...
The pyr*pur.pyr type of nucleic acid triplex has a purine strand that is Hoogsteen-paired with a parallel pyrimidine strand (pyr*pur pair) and that is Watson-Crick-paired with an antiparallel pyrimidine strand (pur.pyr pair). In most cases, the Watson-Crick pair is more stable than the Hoogsteen pair, although stable formation of DNA Hoogsteen-paired duplexes has been reported. Using oligomer t...

This research investigates the integration of evolutionary techniques for symbolic regression. In particular the genetic programming paradigm is used together with other evolutionary computational techniques to develop novel approaches to the improvement of areas of simple preliminary design software using empirical data sets. I t is shown that within this problem domain, conventional genetic p...
The stabilities of eight triple helical pyrimidine.purine.pyrimidine structures comprised of identical sequence but different RNA (R) or DNA (D) strand combinations were measured by quantitative affinity cleavage titration. The differences in equilibrium binding affinities reveal the importance of strand composition. For the sequences studied here, the stabilities of complexes containing a pyri...
It is shown that, for solid caps D of heat balls in Rd+1 with center z0 = (0, 0), there exist Borel measurable functions w on D such that inf w(D) > 0 and ∫ v(z)w(z) dz ≤ v(z0), for every supertemperature v on a neighborhood of D. This disproves a conjecture by N. Suzuki and N.A. Watson. On the other hand, it turns out that there is no such volume mean density, if the bounded domain D in Rd × (...
Watson Crick automata are finite automata working on double strands. Extensive research work has already been done on non deterministic Watson Crick automata and on deterministic Watson Crick automata. Parallel Communicating Watson Crick automata systems have been introduced by E. Czeziler et al. In this paper we discuss about a variant of Watson Crick automata known as the two-way Watson Crick...
