Nanostructuring of YBa2Cu3O7-x films is a challenging task on a way to the high-quality YBa2Cu3O7-x nanodevices because of the sensitivity of YBa2Cu3O7-x thin films to the patterning process. In this work we report on a "cold" nanopatterning procedure used for the structuring of the ultra-thin YBa2Cu3O7-x films by focused ion beam etching with a specially developed protection layer, which can b...

The speckle in ultrasound images has long been thought to contain information related to the tissue microstructure. Many different investigators have analyzed the frequency characteristics of the backscattered signals to estimate the scatterer acoustic concentration and size. Previous work has been mostly restricted to unfocused or weakly focused ultrasound sources, thus limiting its implementa...

background: schizophrenia is a disorder with psychotic symptoms that severely affects personal performance. assessing problem- focused strategies and quality of life (qol) in patients with schizophrenia may help the clinicians to use appropriate interventions. this study was conducted to find the relationship between problem-focused coping strategies and quality of life in schizophrenic patient...

Focused crawling is an efficient mechanism for discovering resources of interest on the web. Link structure is an important property of the web that defines its content. In this thesis, FOCUS a novel focused crawler is described, which primarily uses the link structure of the web in its crawling strategy. It uses currently available search engine APIs, provided by Google, to construct a layered...
