In the centrosymmetric dinuclear title compound, [Dy(2)(C(15)H(12)N(3)O(2)S)(2)(NO(3))(4)]·2CH(3)OH, the two Dy(III) atoms are coordinated by two deprotonated 2-{[2-(1,3-benzothia-zol-2-yl)hydrazinyl-idene]meth-yl}-6-meth-oxy-phenol ligands and four nitrate ions, all of which are chelating. The crystal packing is stabilized by inter-molecular N-H⋯O hydrogen bonds and weak O-H⋯O inter-actions, f...

We describe a memory-based classiication architecture for word sense disambiguation and its application to the senseval evaluation task. For each ambiguous word, a semantic word expert is automatically trained using a memory-based approach. In each expert, selecting the correct sense of a word in a new context is achieved by nding the closest match to stored examples of this task. Advantages of...

Fragment based Quantitative structure activity relationship (QSAR) analysis on reported 25 2-(2-(4-aryloxybenzylidene) hydrazinyl) benzothiazole dataset as antitubercular agents were carried out. Molecules in the current dataset were fragmented into six fragments (R1, R2, R3, R4, R5, R6).Group based QSAR Models were derived using Multiple linear regression (MLR) analysis and selected on the bas...

The title compound, C20H27N3O, was synthesized by condensation reaction of 3,5-di-tert-butyl-4-hy-droxy-benzaldehyde and 2-hydrazinyl-pyridine, and crystallizes in the centrosymmetric monoclinic space group C2/c. The conformation about the C=N bond is E. The dihedral angle between the rings is 18.1 (3)°. An inter-molecular N-H⋯N hydrogen bond generates an R22(8) ring motif. In the crystal, N-H⋯...

Rare-earth phosphates (REPO4) are regarded as one of the promising thermal/environmental barrier coating (T/EBC) materials for SiCf/SiC ceramic matrix composites (SiC-CMCs) owing to their excellent resistance water vapor and CaO–MgO–Al2O3–SiO2 (CMAS). Nevertheless, a relatively high thermal conductivity (?) REPO4 becomes b...

Inhibitors of soluble epoxide hydrolase (sEH) represent one of the novel pharmaceutical approaches for treating hypertension, vascular inflammation, pain and other cardiovascular related diseases. Most of the potent sEH inhibitors reported in literature often suffer from poor solubility and bioavailability. Toward improving pharmacokinetic profile beside favorable potency, two series of 4-benza...

A novel series of 7,7-diphenyl-1,2-dihydroimidazo[2,1-c][1,2,4]triazin-6(7H)-one 6a-h, were easily prepared via reactions of novel 2-hydrazinyl-4,4-diphenyl-1H-imidazol-5(4H)-one (2) with hydrazonoyl halides 3a-h. In addition, we also examined the reaction of compound 2 with commercially available active methylene compounds to afford new pyrazoles containing an imidazolone moiety, expected to b...
