T he cellular nuances revealed by electron microscopy (EM) and electron tomography (ET) would have thrilled microscope pioneer Anton van Leeuwenhoek. Today, researchers can see even more details by pairing up these techniques with fl uorescence microscopy. Kukulski et al. (1) describe a new procedure that further boosts the sensitivity and precision of this combination of imaging techniques. Ce...

Partially ordered sets and metric spaces are used in studying semantics in Computer Science. Sets with both these structures are hence of particular interest. The partial metric spaces introduced by Matthews are an attempt to bring these ideas together in a single axiomatic framework. We consider an appropriate context in which to consider these spaces is as a bitopo-logical space, i.e. a space...

Machine translation (MT) systems do not currently achieve optimal quality translation on free text, whatever translation method they employ. Our hypothesis is that the quality of MT will improve if an MT environment uses output from a variety of MT systems working on the same text. In the latest version of the Pangloss MT project, we collect the results of three translation engines typically, s...
