... in the texts by using lexical cohesion. The first methods are applied to texts, such as expository texts, whose vocabulary is often very specific. As a concept is always expressed by the same ... repetitions are thematically signifi- cant in these texts. The use of lexical cohesion allows to bypass the problem set by texts, such as narratives, in which a concept...

... elastic fibers. Furthermore, the elastomeric properties have been related to the capacity to shift from a weakly globular structure to an extended form, mediated by the Pro- and Gly-rich repeats ... discrete structural patterns allowing them to remain extended, pliable and to function as an energy reservoir, possibly using localized hydrophobic collapse and torsional forces on th...

... time. Finally, we want to relate LMBOT to the STSSG of Sun et al. (2009). To this end, we also introduce the top-down semantics for LMBOT. As expected, both semantics coincide. The top-down semantics ... for sequences, and we refer to their elements using sub- scripts (like t i ). Consequently, a tree t consists of a labeled root node σ followed by a sequence t of its children. T...
