New spectral numerical characterization of DNA sequences
We present new numerical characterization of DNA sequences that is based on the modified graphical representation proposed by Hamori. While Hamori embeds the sequence into Euclidean space, we use analogous embedding into the strong product of graphs, 4 n K P , with weighted edges. Based on this representation, a novel numerical characterization was proposed in [14] which is based on the product...
متن کاملSynthesis, Spectral Characterization and DFT Calculations of New Co(II) Complexes Derived from Benzimidazoles
The synthesis, characterization and quantum-chemical investigations of two new Co(II) complexesderived from fluorescent benzimidazoles have been reported. Two new fluorescentheterocyclic ligands were synthesized from the reduction of imidazo[4',5':3,4]benzo[1,2-c]isoxazole derivatives, and characterized by elemental analyses, IR, mass, and NMR spectra. Coordination of the bidentate ligands ...
متن کاملSpectral Mapping Theorems for Hyponormal Operators
Let T=H+iK be hyponormal and Q be a strictly monotone increasing continuous function on s(H ). We define ~ Q(T ) by ~ Q(T )=Q(H )+iK. In this paper, we show that if z is an isolated eigenvalue of ~ Q(T ), then the corresponding Riesz projection is self-adjoint. Also we introduce Xia spectrum and study the existence of an invariant subspace of an operator ~ Q(T ).

New gallium(III) complex-synthesis, spectral characterization and cytotoxicity
New Ga(III) complex of coumarin-3-carboxylic acid (HCCA) was synthesized and its structure and spectral properties were investigated by elemental analysis, FTIR, FT Raman and NMR measurements. According to the experimental data, the complex formula was suggested. Vibrational frequencies, IR intensities and Raman activities as well as H NMR chemical shifts of HCCA and its Ga(III) complex are pre...
