We summarize all the known properties of the supersymmetric integrable Two Boson equation. We present its nonstandard Lax formulation and tri-Hamiltonian structure, its reduction to the supersymmetric nonlinear Schrödinger equation and the local as well as nonlocal conserved charges. We also present the algebra of the conserved charges and identify its second Hamiltonian structure with the twis...

For the first time, three iron(III) porphyrinato complexes have been synthesized selectively by varying the iodine concentration in the reaction mixture which eventually forms both five and six coordinate complexes with iodide and/or tri-iodide as axial ligands. Combined analysis using single crystal X-ray structure determination, and Mössbauer, (1)H NMR and EPR studies as well as VT magnetic s...

Abstract. The observed neutrino mixing, having a near maximal atmospheric neutrino mixing angle and a large solar mixing angle, is close to tri-bi-maximal, putting leptonic mixing in contrast with the small mixing of the quark sector. We discuss a model in which ∆(27) (a subgroup of SU(3)) is the family symmetry, and tri-bi-maximal mixing directly follows from the vacuum structure enforced by t...

In the title compound, [RuCl(C18H15P)(C26H31N2OP)](CF3O3S)·2C3H6O, the Ru(II) ion is coordinated in a three-legged piano stool, half-sandwich-type geometry by a chlorido ligand, a tri-phenyl-phosphine and a tethered η(6)-(phenyl-p-O-meth-oxy) κ(1)-P N-di-phenyl-phosphino N'-diisopropyl amidine ligand charge-balanced by a trifluormethansulfonate counter-anion. The η(6)-coordination mode of the a...

Lipopolysaccharides were isolated from Cifrobacfer freundii ATCC 8090 by 44% aqueous-phenol fractionation. The lipopolysaccharides were isolated from the phenol phase and phenol-water interphase fractions. Acid hydrolysis yielded glucosamine and a 3-amino sugar identified as 3amino-3,6-dideoxyglucose by comparison with authentic 3-amino-3,6-dideoxyhexoses by ion exchange chromatography. Compari...

We present a new tri-electrode topology for reducing the control voltage for electrostatic actuators. Conventional parallel plate actuators are dual-electrode systems, formed by the MEMS structure and the drive electrode. By placing a perforated intermediate electrode between these elements, a tri-electrode configuration is formed. This topology enables a low voltage on the intermediate electro...

IN THE CRYSTAL STRUCTURE OF THE TITLE COMPOUND [SYSTEMATIC NAME: bis-(tri-ethyl-ammonium) 2,5-di-chloro-3,6-dioxo-cyclo-hexa-1,4-diene-1,4-diolate], 2C6H16N(+)·C6Cl2O4 (2-), the chloranilate anion lies on an inversion center. The tri-ethyl-ammonium cations are linked on both sides of the anion via bifurcated N-H⋯(O,O) and weak C-H⋯O hydrogen bonds to give a centrosymmetric 2:1 aggregate. The 2:...

Methanolysis of 2,4,6-tri-O-benzoyl-2,3-dibromo-3-deoxy-D-altrono-1,5-lactone gave methyl 3-bromo-3-deoxy-2,4,6-tri-O-benzoyl-alpha-D-ribo-hex-2-ulofuranosonat e (3) and the anomeric mixture of the analogous 4,6-di-O-benzoyl derivative, having HO-2 free. Compound 3 was subjected to debromination with tributyltin hydride and tributyltin deuteride in the presence of 2,2'-azo-bisisobutyronitrile a...

A face-sharing bi-icosahedral motif is proposed as a candidate structure of the magic cluster, Al23(-), on the basis of DFT calculations. The structure can be viewed as a quasi-molecule made of two Al13 (D3d) superatoms with an open electronic configuration via constructive overlap of 1F and 2P superatomic orbitals. A face-sharing tri-icosahedral motif is also predicted for Al33(-).
