A method is presented to obtain the change in potential and relevant wavefunction of a linear system ordinary differential equations containing spectral parameter, when that perturbed finite number discrete eigenvalues are added or removed from spectrum. Some explicit formulas derived for those changes by introducing certain fundamental integral corresponding unperturbed systems. This generaliz...

In this study, NiTi thin films were deposited on the glass and NaCl substrates by means of magnetron sputtering method. The influence of aging temperature, over the range 300-500 oC, on phase transformation and mechanical properties of the sputtered NiTi thin films were studied by differential scanning calorimetry (DSC) and nano-indentation assay, respectively. The DSC curves showed that the ag...

for a given riemannian manifold (m,g),it is an interesting question to study the existence of a conformal diffemorphism (also called as a conformal transformation) f : m ! m such that the metric g? = fg has one of the following properties: (i)(m; g?) has constant scalar curvature. (ii)(m; g?) is an einstein manifold.

A highly efficient transformation system mediated by polyethylene glycol was developed for the cultivated mushroom Pleurotus ostreatus. Eighty to 180 integrative and stable-resistant colonies appeared per mg of DNA per 10 viable protoplasts in a transformation experiment with the hygromycin B phosphotransferase gene (hph), which is about 40–1800 times higher than that previously reported in P. ...
