Movement Rules Revisited
نویسنده
چکیده
The Praguian approach to formal description of language (in detail, see Sgall et aI. 1986), works with dependency syntax and includes the topicfocus articulation into the (underlying, tectogrammatical) syntactic representations of sentences, using the left-to-right order of the nodes of the dependency tree for that purpose. The edges of the tree denote the dependency relations and the nodes carry complex labels indicating their lexical and morphological values (e.g. Preterite). No nonterminals and no nodes corresponding to function words (auxiliaries, prepositions, conjunctions, articles) are present in the tree. Counterparts of function words (and function morphemes) are parts of the complex symbols of the nodes. Instead of using the notion of phrase, we work with subtrees (i.e. the governor and its dependents, or all its subordinate nodes, where "subordinate" is the transitive closure of "dependent"). The present paper concentrates on a motivating discussion pointing out the reasons for distinguishing three layers of the order of lexical occurrences (Sect. 1), presenting a characterization of movement rules (Sect. 2), discussing certain relevant relationships between the level of syntax and that of morphernics (Sect. 3), and sketching a possibility how to proceed from surface (morphemics) to (underlying) syntax (Sect. 4). A way how to formalize the description of (underlying) syntactic slructure is briefly outlined in Section 5. 1. Three layers of word o rder

Simon-gutowitz Bidirectional Traffic Model Revisited
The Simon-Gutowitz bidirectional traffic model (Phys. Rev. E 57, 2441 (1998)) is revisited in this letter. We found that passing cars get stuck with oncoming cars before returning to their home lanes. This provokes the occurrence of wide jams on both lanes. We have rectified the rules for lane changing. Then, the wide jams disappear and the revisited model can describe well the realistic bidire...
متن کاملWeinberg like sum rules revisited
The generalized Weinberg sum rules containing the difference of isovector vector and axial-vector spectral functions saturated by both finite and infinite number of narrow resonances are considered. We summarize the status of these sum rules and analyze their overall agreement with phenomenological Lagrangians, low-energy relations, parity doubling, hadron string models, and experimental data.
متن کاملAttention in cat revisited. A critical review of a set of brain explorations in fully alert animals
Motionless attentive states Our major finding was that expecting and attending differed by their ECoG correlates. Expecting the mouse to appear at the hole elicited very characteristic trains of rhythms at 12 to 14 Hz confined to a specific site of the anterior cortex, the post-cruciate S1 somato-sensory receiving area. Based on previously described human “sensori-motor” or “rolandic” or “wicke...
