Thus, the system handles most plural forms, morphological flexions and derivations as in expressions, expresses, expressed, expressive.
However, these models do not take into account effects of cell division and spatial restrictions of the meristem and, accordingly, cannot explain the derivation of morphological features such as homeostatic control despite cell proliferation in the wild type and drastic morphological changes in clv and wus mutants.
With the exception of the latter, the distinction in antigen expression between many of the cell lines was quantitative rather than qualitative and the emergent picture is one of random expression of individual determinants on several disparate types of cancer cells, rather than restriction to cells of a given morphological type or histogenic derivation.
Here we report the first study to investigate morphological processing where derivational steps are not overtly marked (e.g., bridge-N>bridge-V) i.e., zero-derivation (Aronoff, 1980).
Although conversion has traditionally been considered to be morphological in nature (zero-derivation), different authors have suggested a syntactic approach, in which lexemes are deprived of categorial information in the lexicon and are put to use in different syntactic contexts.
This study is the first to provide evidence for the processing of zero derivation, and demonstrates that morphological processing cannot be reduced to surface form-based segmentation.
Quantitative analysis of the images included derivation of parameters to assess morphological features of spheroids and cell content and complexity (Fig. 5 ).
The remainder of this article is organized as follows: Section 2 expounds the derivation of pattern classification method using adaptive rank-order morphological filter.
As the brief review above makes clear, the main morphological components of the DS can all be explained by the derivation of the affected tissues from neural crest.
