We have extended, from order 12 through order 25, the high-temperature series expansions (in zero magnetic field) for the spin-spin correlations of the spinS Ising models on the square, simple-cubic and body-centered-cubic lattices. On the basis of this large set of data, we confirm accurately the validity of the scaling and universality hypotheses by resuming several tests which involve the co...

recently, a large amount of studies have been related to nonlinear systems with multi-degrees of freedom as well as continuous systems. the purpose of this paper is to optimize passive vibration absorbers in linear and nonlinear states for an euler-bernoulli beam with a nonlinear vibratory behavior under concentrated moving load. the goal parameter in the optimization is maximum deflection of t...

Solution self-assembly of block copolymers into inverse bicontinuous cubic mesophases is a promising new approach for creating porous polymer films and monoliths with highly organized bicontinuous mesoporous networks. Here we report the direct self-assembly of block copolymers with branched hydrophilic blocks into large monoliths consisting of the inverse bicontinuous cubic structures of the bl...

We consider a two-component system of cubic nonlinear Schrödinger equations in one space dimension. show that each component the solutions to this behaves like free solution large time and scattering profiles satisfy crucially restricted condition. This restriction results from non-trivial long-range interactions.

The (T, c)-dependent phase diagrams of two gangliosides, GM I and GM I(acetyl), have been explored, in spite of the frequent occurrence of metastable states. In GMT two lamellar, one hexagonal and two cubic (aspects ( 5 and 13) phases were identified, in addition to the isotropic micellar solution. In GMT(acetyl) two of the phases are cubic (aspects 8 and 13), one is the fluid isotropic solutio...

A new synthesis route to high-quality large mesoporous cubic Ia3d silica is reported, utilizing a triblock copolymer (EO20PO70EO20)-butanol mixture for the structure direction in aqueous solution.
