Regenerative medicine, deals with functional reconstruction of damaged tissues or organs after severe injuries chronic diseases, while body's natural responses are not sufficient. In this field, stem cells due to their exclusive potential in self-renewal and differentiation into other cell types, are the main sources of functional cells in regenerative medicine. However, challenges in stem cell...

Symmetry breaking is commonly found in self-organized collective decision making. It serves an important functional role, specifically in biological and bio-inspired systems. The analysis of symmetry breaking is thus an important key to understanding self-organized decision making. However, in many systems of practical importance available analytic methods cannot be applied due to the complexit...

In this paper, we present a systematic approach in building a named entity annotated corpus while at the same time building rules to recognize Vietnamese named entities. The resulting open source system achieves an F-measure of 83%, which is better ...
