... of peroxisomes were observed and the cyto- plasm of the cells was crowded with peroxisomes [22,23]. In contrast, deletion of PEX11 resulted in a strong decrease in peroxisome numbers, which was paralleled ... pro- teins. Although different protease activities have been detected in peroxisomes [54], so far only one gene encoding a peroxisomal protease, a Lon protease, has been...

We analyse experimental data as well as models in two distinct cases: the relaxation- like oscillations seen in yeast extracts, and the sinusoidal Hopf oscillations seen in intact yeast ... 80 min )1 ; this point is the same point as that analysed in [33].) Originally, this model was intended to model oscillations in intact yeast cells but, from the point of...

Formu- lating lemmatisation as a tagging task allows the use of advanced tagging techniques, and the efficient in- tegration ... Learning pre- sented in Shen et al. (2007). We chose this model since it has been shown to be easily adaptable for solving a wide set of tagging and chunking tasks ob- taining state-o...
