Hay (2001) argues that there is a type of frequency called relative frequency which has an important effect on the processing of derived forms through a two-route model of morphological processing. She argues that complex forms with a frequency lower than the frequency of their base forms (e.g. uncommon) are more likely to be perceived as decomposable than a complex form with a higher frequency than the frequency of their base words (e.g. uncanny). She reports the results of an experiment which provides evidence for this view. Since it is reasonable to assume that these relative frequency effects also occur in other languages, I replicated her experiment for Dutch. The results of my experiment suggest that relative frequency effects are observed in the processing of Dutch derived forms.Show less

A ruthenium coated diffraction grating was inspected using atomic force microscopy (AFM) prior to and after exposure to high intensity EUV light under a grazing incident angle, in order to determine whether such change occurs due to EUV irradiation. AFM images show signs of structural change, most noticeable at the bottom of the grating, possibly caused by heating through absorption of the EUV radiation. Closer study of the top grating section showed signs of a change in thin film morphology as well. We used statistical and dynamic scaling analysis of multiple AFM images to verify this hypothesis, but it could not confirm this change beyond doubt, nor dismiss the claims outright. Possible explanations for a change in thin film morphology were proposed, such as thermally assisted diffusion causing roughening and coarsening, as well as oxidation of the layer.Show less
