The presence of bound water in the solution structure of the IgG binding domain of streptococcal protein G has been investigated by nuclear magnetic resonance using three-dimensional 1H rotating frame Overhauser 1H-15N multiple quantum coherence spectroscopy. The backbone amide protons of three residues, Ala20, Gln32 and Tyr33, are found to be in close proximity to bound water. Examination of t...

In this paper‎, ‎using the discrete Fourier transform in the finite-dimensional Hilbert space C^n‎, ‎a class of nonRieszable equal norm tight frames is introduced ‎and‎ using this class, a bound for Fiechtinger Conjecture is presented. By the Fiechtinger Conjecture that has been proved recently, for given A,C>0 there exists a universal constant delta>0 independent of $n$ such that every C-equal...
