We have studied the three-band Peierls-Hubbard model describing the Cu-O layers in high-T c superconductors by using Lanczos diagonalization and assuming infinite mass for the ions. When the system is doped with one hole, and for λ (the electron-lattice coupling strength) greater than a critical value, we found that the oxygens around one Cu contract and the hole self-traps forming a lattice an...

Biofabrication of metallic nanoparticles have attracted the researchers of various disciplines for the past few decades, due to their wide range of applications in the various fields of electronics, textiles industries, nano medicine, biopharmacy and biotechnology. Keeping in view the above important applications, we have successfully biosynthesized the silver nanoparticles (AgNPs) using leaf e...

satellite imagery was used as a rapid and spatially explicit method to delineate crop residue cover and to estimate the use and intensity of conservation tillage. the potential of multispectral high-spatial resolution of worldview-2 local data was evaluated using 11 satellite spectral indices and linear spectral unmixing analysis (lsua). experimental plots were examined; residue cover was measu...

Intelligent data analysis (IDA) i s an interdisciplinary study concerned with the effective analysis of data. This paper will briefly look at some of the key issues in intelligent data analysis, discuss the opportunit ies f o r soft computing in this context, and present .several IDA case studies in which soft computing has played key roles. These studies are all concerned with complex real-wor...

Five rare earth complexeslanthanum(III),praseodymium(III),neodymium(III), samarium(III) and europium(III) have been synthesized from Schiff base ligand (N,N-bis (2-hydroxy-1-naphthylidene) acetylhydrazone). The complexes were characterized based on elemental analysis, molar conductance, ultraviolet, infrared, mass, thermogravimetric and powder X-ray diffraction studies. Infrared spectra sug...
