We consider array experiments that compare expression levels of a high number of genes in two cell lines with few repetitions and with no subject effect. We develop a statistical model that illustrates under which assumptions thresholding is optimal in the analysis of such microarray data. The results of our model explain the success of the empirical rule of two-fold change. We illustrate a thr...

A range of mostly new oxovanadium(IV) complexes is described. They contain coordinated Schiff bases, made from simple dipeptides (glycylglycine, glycylsarcosine, L-alanylglycine, L-alanyl-L-alanine, D,L-alanyl-D,L-alanine and L-serylglycine), and salicylaldehyde. The compounds are characterised and the nature of their coordination spheres shown by analysis, TLC, by appropriate spectroscopy (EPR...

Crystalline Structure and Dielectric Properties of Li1+x-yNb1-x-3yTix+4yO3 M-Phase Solid Solutions

The structure and dielectric properties of the so-called M-phase solid solutions in the Li2O-Nb2O5-TiO2 system have been investigated. Detailed studies of the lattice parameters of these phases agree well with structure models based on intergrowths of LiNbO3 slabs with a titanium-rich corundum-type layer. The relative permittivity ranges from ~80 to ~55; microwave quality factors increase with ...

DIELECTRIC PROPERTIES OF Li1+x-yNb1-x-3yTix+4yO3 M-PHASE SOLID SOLUTIONS

The structure and dielectric properties of the so-called “M-phase” solid solutions in the Li2O-Nb2O5-TiO2 system have been investigated. Detailed studies of the lattice parameters of these phases agree well with structure models based on intergrowths of LiNbO3 slabs with a Ti-rich corundum-type layer. The relative permittivity ranges from ~80 to ~55; microwave quality factors increase with the ...
