Formal Concept Analysis (FCA) can be used to analyze data given in the form of a formal context. In particular, FCA provides efficient algorithms for computing a minimal basis of the implications holding in the context. In this paper, we extend classical FCA by considering data that are represented by relational structures rather than formal contexts, and by replacing atomic attributes by compl...

This paper assesses the impact of medical care on changes in mortality in east Germany and Poland before and after the political transition, with west Germany included for comparison. Building upon Rutstein's concept of unnecessary untimely deaths, we calculated the contribution of conditions considered responsive to medical care or health policy to changes in life expectancy between birth and ...

We report results of a study that involved the creation of knowledge bases of concepts from large, operational textual databases. Two East-bloc computing knowledge bases, both based on a semantic network structure, were created automatically using two statistical algorithms. With the help of four East-bloc computing experts, we evaluated the two knowledge bases in detail in a concept-associatio...

Pathogens such as MERS-CoV, influenza A/H5N1 and influenza A/H7N9 are currently generating sporadic clusters of spillover human cases from animal reservoirs. The lack of a clear human epidemic suggests that the basic reproductive number R0 is below or very close to one for all three infections. However, robust cluster-based estimates for low R0 values are still desirable so as to help prioritis...

The Near East Fertile Crescent is well recognized as a primary center of barley origin, diversity, and domestication. A large number of wild barleys have been collected from the Tibetan Plateau, which is characterized by an extreme environment. We used genome-wide diversity array technology markers to analyze the genotypic division between wild barley from the Near East and Tibet. Our results c...

Japan has the amazing beauty of nature and a four-season climate that reflects the country’s geography. As a volcanic country that locates to the east end of the Eurasian continent and faces the Japan Trench and Pacific Ocean, Japan has also experienced a large number of natural disasters. Over a long period of history, people in Japan have experienced and overcome earthquakes, tsunami, typhoon...
