background: retinoic acid as one of the most important regulators for cell differentiation was examined in this study for differentiation of human umbilical mesenchymal cells (hucm). methods: after isolation, hucm were evaluated for mesenchymal stem cell properties by flow cytometry and alkaline phosphatase assay. also, doubling time of the cells and their differentiation potential into adipoge...

Due to the rapid growth in the volume of biomedical literature, there is an increasing requirement for high-performance semantic search systems, which allow biologists to perform precise searches for events of interest. Such systems are usually trained on corpora of documents that contain manually annotated events. Until recently, these corpora, and hence the event extraction systems trained on...

Language design and implementation are still one of the challenges in computer science. Programmers use a variety of languages in their daily work, and new languages appear frequently. With formal methods for programming language description a language designer has a chance to automatically generate a compiler or an interpreter. Unfortunately, compiler generators nowadays use linear textual spe...

For designing and developing complex, correct and reliable systems formal methods are the most beneficial approach. However, a formal methodology could be difficult for industry practitioners due to its mathematical notation. Hence it needs to be supported by more approachable platform, which would give guidance both for industry and research world representatives. The Unified Modelling Languag...

A 23 year follow up of deaths in a population of mentally disordered patients was carried out, and a typical case history is reported. A quarter (71) of the deaths reported were unnatural, verdicts of suicide or accidental death or open verdicts having been recorded. For men in most age groups the proportion of deaths by suicide was two to three times greater than in the general population in 1...

We investigate the English verbs climb and cut, cited as counterexamples to manner/result complementarity: the proposal that verbs lexicalize either manner or result meaning components, but not both. Once their lexicalized meaning is identified and distinguished from contextually determined elements of meaning, cut and climb conform to manner/result complementarity. We show that cut is basicall...

How can machines help us to manipulate and structure audiovisual media in ways that are always novel and are uniquely ours? How can such construction happen in real time, with no precise planning or guidance given by the user? The Emonic Environment (EE), the system described in this paper, enables improvisational construction and navigation of media space, both by individuals and by groups. Pa...
