Combinator Parsers - From Toys to Tools

We develop, in a stepwise fashion, a set of parser combinators for constructing deterministic, error-correcting parsers. The only restriction on the grammar is that it is not left recursive. Extensive use is made of lazy evaluation, and the parsers constructed “analyze themselves”. Our new combinators may be used for the construction of large parsers to be used in compilers in practical use.

Turning manure into gold

At a time of global warming, growing environmental concerns and a political situation that is making many industrialised countries critically review their dependency on Middle Eastern oil, the need to develop alternatives to fossil fuels is becoming increasingly important. And this is not just a recurring demand from environmentalists; most industrialised countries signed the Kyoto Treaty, comm...

Turning Meiosis into Mitosis

Apomixis, or asexual clonal reproduction through seeds, is of immense interest due to its potential application in agriculture. One key element of apomixis is apomeiosis, a deregulation of meiosis that results in a mitotic-like division. We isolated and characterised a novel gene that is directly involved in controlling entry into the second meiotic division. By combining a mutation in this gen...
