... secreted and bind to the type I and type II receptors on the cell surface. These receptors are serine ⁄ threonine kinase receptors with a single transmembrane domain. Bind- ing of the ligand to the ... the receptor complex induces the type II receptor to phosphorylate the type I receptor, which then leads to activation of the type I receptor. The signal is passed on to the s...

... is very of- ten seen as one of the main drawbacks of the dialec- tometry techniques and dialectometry itself. Two at- tempts to overcome this drawback are presented in Nerbonne (2005) and Nerbonne ... ’thirty’. Factor analysis has shown that 3 factors are most im- portant, explaining 35% of the total amount of vari- ance. The main drawback of applying this technique in dia...

... structures: a syntactic dependency tree (ID tree) and a topological de- pendency tree (LP tree). While edges of the ID tree are labeled by syntactic roles, those of the LP tree are labeled by topological ... The shape of the LP tree is a flattening of the ID tree’s obtained by allowing nodes to ‘climb up’ to land in an appropriate field at a host node where that field is availa...
