a r t i c l e i n f o As most bivalve mollusks are filter feeders or deposit feeders—predatory septibranchs (Poromyacea) being the notable exception—they are closely linked with the activity of primary producers. Perhaps this is nowhere more evident than in shallow water habitats influenced by seasonal phytoplankton blooms. In these systems, photoautotrophs are capable of changing the physical ...
In the framework of spherical geometry for jellium and local spin density approximation, we have obtained the equilibrium rs values, r̄s(N, ζ), of neutral and singly ionized “generic” N -electron clusters for their various spin polarizations, ζ. Our results reveal that r̄s(N, ζ) as a function of ζ behaves differently depending on whether N corresponds to a closed-shell or an openshell cluster. Th...
We describe the CoNLL-2000 shared task: dividing text into syntactically related nonoverlapping groups of words, so-called text chunking. We give background information on the data sets, present a general overview of the systems that have taken part in the shared task and briefly discuss their performance.
Practice, and the performance improvement that it engenders, has long been a major topic in psychology. In this paper, both experimental and theoretical approaches are employed in an investigation of the mechanisms underlying this improvement. On the experimental side, it is argued that a single law, the power law of practice, adequately describes all of the practice data. On the theoretical si...
We present a new translation model that include undecorated hierarchical-style phrase rules, decorated source-syntax rules, and partially decorated rules. Results show an increase in translation performance of up to 0.8% BLEU for German–English translation when trained on the news-commentary corpus, using syntactic annotation from a source language parser. We also experimented with annotation f...
This paper tries to discuss the interrelation between prosody and syntax by clarifying some syntactic constraints in Chinese prosodic segmentation and grouping. The main attention will be paid to search for (1) possible correlation between prosodic breaks and syntactic construction; (2) possible correlation between prosodic breaks and POS; and (3) the role of syntactic and lexical information i...
