Using multiunit recording of action potentials from the whole nerve with the aid of external perfusion, we investigated the effects of dopamine (DOP) agonists that are involved in modulatory actions on synaptic transmission in the isolated labyrinth preparations of frogs. The external application of DOP (0.1-1 mM), the D(1) agonist chloro-APB hydrobromide (CAPB, 50-100 microM) and the D2 agonis...

1. I n t r o d u c t i o n Data-Oriented Parsing (DOP) models of natural language embody the assumpt ion that human language perception and pr~duction works with representations of past language experiences, rather than with abstract grammar rules (cf. Bod 1992, 95; Scha 1992; Sima'an 1995; Rajman 1995). DOP models therefore maintaiIi hu'gc corpora of linguistic representations of previously oc...

The degree of polarization (DOP) of the light reflected from the optic nerve head has been assessed by means of a polarimetric scanning laser ophthalmoscope as a function of the age of the participants. Four fundus images corresponding to independent polarization states in the recording pathway were used to compute the spatially-resolved DOP. This was not uniform across the optic nerve head and...

This paper explores a parsimonious approach to Data-Oriented Parsing. While allowing, in principle, all possible subtrees of trees in the treebank to be productive elements, our approach aims at finding a manageable subset of these trees that can accurately describe empirical distributions over phrase-structure trees. The proposed algorithm leads to computationally much more tracktable parsers,...

Purpose : A new method of calibration of the displacement of the cornea1 reflex in relation to the angular deviation was carried out on a population of normal subjects. Methods : The position of the cornea1 reflex was studied in 15 normal adult subjects, emmetropic and orthophoric. Each eye, photographed individually, was situated perpendicularly at the zero of a tangential scale. Slides taken ...

A novel, simple, sensitive and effective method has been developed for preconcentration of Hg(II) on nano-Fe3O4-DOP-ED solid-phase extraction adsorbent. In this paper, Dioctyl phthalate (DOP) was used to encapsulate nano-Fe3O4 and produce a nano-Fe3O4-DOP sorbent based new sorbent was prepared. This was treated with ethylenediamine (ED) in another solvent-free procedure for the formation of a n...

The Data Oriented Parsing (DOP) model currently achieves state-ofthe-art parsing on benchmark corpora. However, existing DOP parameter estimation methods are known to be biased, and ad hoc adjustments are needed in order to reduce the effects of these biases on performance. This paper presents a novel estimation procedure that exploits a unique property of DOP: different derivations can generat...

Data-Oriented Parsing (dop) ranks among the best parsing schemes, pairing state-of-the art parsing accuracy to the psycholinguistic insight that larger chunks of syntactic structures are relevant grammatical and probabilistic units. Parsing with the dop-model, however, seems to involve a lot of CPU cycles and a considerable amount of double work, brought on by the concept of multiple derivation...
