Degree of Polarization (DOP) is an important property of light sources. It directly relates to the accuracy of optical component characterization, the sensitivity of sensor systems, and the quality of optical signals in optical communication systems. Therefore, the accurate and fast characterization of DOP is increasingly important. This article first reviews the fundamentals of DOP and summari...

We present an LFG-DOP parser which uses fragments from LFG-annotated sentences to parse new sentences. Experiments with the Verbmobil and Homecentre corpora show that (1) Viterbi n best search performs about 100 times faster than Monte Carlo search while both achieve the same accuracy; (2) the DOP hypothesis which states that parse accuracy increases with increasing fragment size is confirmed f...

In this paper I present ongoing work on the data-oriented parsing (DOP) model. In previous work, DOP was tested on a cleaned-up set of analyzed part-of-speech strings from the Penn Treebank, achieving excellent test results. This left, however, two important questions unanswered: (1) how does DOP perform if tested on unedited data, and (2) how can DOP be used for parsing word strings that conta...

Data Oriented Parsing (DOP) is based on the idea of processing new input by combining fragments (associated with some probabilities) that are extracted from a treebank. In the simplest case these fragments are subparts of simple phrase structure trees (Tree-DOP). The approach is attractive in many ways but the impoverished representational basis is a serious drawback from a linguistic point of ...

We show how disordered media allow to increase the local degree of polarization (DOP) of an arbitrary (partial) polarized incident beam. The role of cross-scattering coefficients is emphasized, together with the probability density functions (PDF) of the scattering DOP. The average DOP of scattering is calculated versus the incident illumination DOP.

An approach to find the global optimal solution of the dilution of precision (DOP) problem is presented. The DOP optimization problem considered assumes an environment comprising multiple randomly pre-deployed sensors (or navigation sources) and an additional sensor is to be introduced at the location that minimizes variations of the DOP problem (e.g., weighted geometric DOP (WGDOP), horizontal...

Dopaminergic inputs are sensed on the cell surface by the seven-transmembrane dopamine receptors that belong to a superfamily of G-protein-coupled receptors (GPCRs). Dopamine receptors are classified as D1-like or D2-like receptors based on their homology and pharmacological profiles. In addition to well established G-protein coupled mechanism of dopamine receptors in mammalian system they can ...

Given a sequence of samples from an unknown probability distribution, a statistical estimator aims at providing an approximate guess of the distribution by utilizing statistics from the samples. One crucial property of a ‘good’ estimator is that its guess approaches the unknown distribution as the sample sequence grows large. This property is called consistency. This paper concerns estimators f...

Dendrobium officinale extract shows potent anti-fatigue effects; however, the active substance responsible for these effects remains undetermined. A glucomannan with a huge molecular size of 730 kDa, called DOP, was identified as the unique authentication marker of this expensive herb. DOP exhibited immunomodulating effects on macrophages and lymphocytes in our previous study. Clinical reports ...
