... acids or their metabolites are ligands for receptors involved in cancer. Phytol, phytanic acid and other branched-chain lipids are known to be high- affinity ligands for various receptors [99–104], ... are agonists for PPAR-d or antagonists for PPAR-c, and this is the molecular basis for cancer formation, at least in some model systems. These theories merit further investiga- ti...

The algorithm has a for- ward variable α and a backward variable β which are calculated in the standard way (Deligne and Bimbot, 1995). ... languages – and efficient. Unlike the pre- vious unsupervised system, and unlike the super- vised and semi-supervised systems we mentioned, our model can be used for bot...

We apply this sampler to build phrase-based and hierarchical translation models and evaluate their performance on small and large corpora. 2 ... available for the IWSLT work- shop (Eck and Hori, 2005). The sparse counts and high reordering for this corpus means the GIZA++ model produces very poor alignments. Table...
