QUANTUM CONFINEMENT OF MOBILE \(\mathbf{N a}^{\mathbf{+}}\) IONS IN SODIUM SILICATE GLASSY NANOPARTICLES
The confinement of mobile \(\mathrm{Na}^{+}\)ions in sodium silicate glassy nanoparticles is considered quantum mechanically to be under the influence of a spherical box potential. The values for the energies of mobile \(\mathrm{Na}^{+}\)ions are determined...

CONSERVATION OF THE UPSTREAM OPEN READING FRAMES IN THE GENES FOR THE ERB-B2 RECEPTOR TYROSINE KINASE 2 IN VERTEBRATES
In humans a short open reading frame (ORF) precedes the sequence of the erb-b2 receptor tyrosine kinase 2 (ERB-B2). It is established that the upstream ORF plays an important role in ERB-B2 gene expression. In this report we show that an upstream ORF is pre...
