The GTPase Cdc42 specifies polarity in various biological processes. Kesavan et al. (2009) now demonstrate that Cdc42 also regulates epithelial cell polarity in the developing mouse pancreas, where it is required for tubule formation and maintenance. Furthermore, the polarization of epithelial tissue influences the differentiation of pancreatic progenitor cells, linking cell polarity to cell sp...

With the volume of daily news growing to sizes too big to handle for any individual human, there is a clear need for effective search algorithms. Since traditional bag-of-words approaches are inherently limited since they ignore much of the information that is embedded in the structure of the text, we propose a linguistic approach to search called Destiny in this paper. With Destiny, sentences,...
