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 ...

New experimental tests of nuclear supersymmetry are suggested. They involve the measurement of oneand two-nucleon transfer reactions between nuclei that belong to the same supermultiplet. These reactions provide a direct test of the ‘fermionic’ sector, i.e. of the operators that change a boson into a fermion or vice versa. We present some theoretical predictions for the supersymmetric quartet o...

Quartets of Au nanorods were designed by combining the methodologies of lateral and longitudinal assemblies. A high electric field prevailing at the quartet junctions results in large enhancement in the Raman signals of molecules. FDTD simulations showed that the displacement of the lateral dimers in quartets expands the scope of hot spot distribution.

A technique is described for the simultaneous and controlled random mutation of all three heavy or light chain complementaritj-determining regions (CDRs) in a single-chain Fv specific for the 0 polysaccharide of SalmoneUla serogroup B. Sense oligonucleotides were synthesized such that the central bases encoding a CDR were randomized by equimolar spiking with A, G, C, and T at a level of 10%/1 w...

and (F ×G) = fabcF G. Under the assumption that BRS singlets have positive metric, it is proved that Vphys has positive semidefinite in such a way that BRS quartet particles appear only in zero norm. One finds from the BRS transformation that for each colour a, a set of massless asymptotic fields χ, β, γ, γ̄ form a BRS quartet. The Noether current corresponding to the conservation of the colour ...

u ′t + Aut = ft, t ∈ 0,T u0 = u0, where Au,vH = Bu,v ∀u,v ∈ V ⊂ H ⊂ V ′. We showed that if the bilinear form B is coercive then the linear mapping A is an isomorphism from V onto V’. Recall that there exists a family of H-orthonormal eigenfunctions for A such that ||Awk ||H = |λk| ||wk ||H = |λk|→ ∞ as k → ∞. Then A is clearly not bounded as a mapping from H into H. If we define D...
