Opis:: X-ray scattering methods suitable for the investigation of the morphology and chemical composition of self-organized quantum dots and quantum wires are reviewed. Their application is demonstrated in experimental examples showing that a combination of small angle X-ray scattering with high-resolution X-ray diffraction can reveal both the shape and the chemical composition of the self-organized objects.

Opis:: This paper discusses recently introduced kind of linguistically motivated restriction placed on tree-controlled grammars-context-free grammars with some root-to-leaf paths in their derivation trees restricted by a control language. We deal with restrictions placed on n greater-than or equal to 1 paths controlled by a deterministic context-free language, and we recall several basic properties of such a rewriting system. Then, we study the possibilities of corresponding parsing methods working in polynomial time and demonstrate that some non-context-free languages can be generated by this regulated rewriting model. Furthermore, we illustrate the syntax analysis of LL grammars with controlled paths. Finally, we briefly discuss how to base parsing methods on bottom-up syntax-analysis.
