Eckert (2008) asserts, based on empirical findings, that cues exist within indexical fields: Each cue is indexed with multiple potential meanings, one of which is activated by the perspective of the listener as well as the context and content of the utterance. What is less established is how multiple cues, indexed with inter-related potential meanings, are effectuated. For example, when three d...

In this article, we consider linearly stable elliptic fixed points (equilibrium) for a symplectic vector field and we prove generic results of super-exponential stability for nearby solutions. We will focus on the neighbourhood of elliptic fixed points but the case of linearly stable isotropic reducible invariant tori in an Hamiltonian system should be similar. More specifically, Morbidelli and...

The present study is an extension of the cooperative kinematics (CK) approach (Bahar, I.; Erman, B.; Monnerie, L.Macromolecules 1992, 25, 6309), which has been demonstrated to give an efficient and realistic account of the mechanism of local relaxational processes in polyethylene (PE). In the present work, the effects of (i) departure from tetrahedral backbone geometry and (ii) differences in t...
