X-ray absorption fine structure (XAFS) measurements as a function of temperature have been carried out at the Mn K edge for La0.7Ca0.3Mn1-xTixO3 and La0.7Ca0.3Mn1-yGayO3 (x and y = 0.01 to 0.10) an
An accurate description of plasma structure, i.e.
The density functional approach with ab initio pseudopotentials has been used to calculate the static dielectric matrices for Diamond, Si, Ge and LiCl form first principles for a regular grid of q-
Photonic structures constructed from square arrays of air holes in Si3Nx membranes are locally imaged by near-field optical microscopy in illumination mode.

Opportunistic networks are a new and specific type of mobile peer-to-peer networks where end-to-end connectivity cannot be assumed.
Ten years ago it was proposed that two dimensional crystals melt in two stages through an intermediate phase which exhibits quasi-long range orientational order of the local lattice but only short
The local linear wavelet neural network is an improvement of wavelet network and commonly used learning algorithm is gradient descent method.
We report on magnetization measurements performed on a series of Fe(x)Ni(1-x)Zr(2) superconducting metallic glasses with 0 = x = 0.5 using the Hall effect of a nearby two-dimensional electron gas (
Using x-ray submicrobeam, we spatially mapped the strain in epitaxial La1-xSrxMnO3 films grown on SrTiO3(001) bicrystal substrates.
