MAJORITY-VOTE MODEL ON (3, 4, 6, 4) AND (34, 6) ARCHIMEDEAN LATTICES

The KCOD Model on (3, 4, 6, 4) and (34, 6) Archimedean Lattices

Through Monte Carlo simulations, we studied the critical properties of kinetic models of continuous opinion dynamics on (3, 4, 6, 4) and (34, 6) Archimedean lattices. We obtain pc and the critical exponents’ ratio from extensive Monte Carlo studies and finite size scaling. The calculated values of the critical points and Binder cumulant are pc = 0.085(6) and O∗ 4 = 0.605(9); and pc = 0.146(5) a...

3-(4-Meth­oxy­benzo­yl)-6-nitro­coumarin

In the title coumarin derivative (also known as 2H-chromen-2-one or 2H-1-benzopyran-2-one), C17H11NO6, the coumarin ring system is nearly planar, with a dihedral angle of 3.35 (9)° between the pyrone and the benzene rings. The dihedral angle between the planes formed by the coumarin ring system and the benzene substituent is 54.60 (7)°, clearly showing the non-coplanarity of the whole aromatic ...

Algebraic 3 × 3 , 4 × 4 and 6 × 6 Space - Time Codes with non - vanishing Determinants

In this paper we present algebraic constructions of 3×3, 4× 4 and 6 × 6 Space-Time Codes, achieving full rate and full diversity. These codes have non-vanishing (in fact fixed) minimum determinants when the rate goes to infinity. Their construction is based on cyclic algebras with center equal to an algebraic field based on cyclotomic fields .

Ca(4)IrO(6), Ca(3)MgIrO(6) and Ca(3)ZnIrO(6).

Single crystals of tetracalcium iridium hexaoxide, Ca(4)IrO(6), tricalcium magnesium iridium hexaoxide, Ca(3)MgIrO(6), and tricalcium zinc iridium hexaoxide, Ca(3)ZnIrO(6), were prepared via high-temperature flux growth and structurally characterized by single-crystal X-ray diffraction. The three compounds are isostructural and adopt the K(4)CdCl(6) structure type, comprised of chains of altern...
