This paper proposes a dependency parsing method that uses bilingual constraints to improve the accuracy of parsing bilingual texts (bitexts). In our method, a targetside tree fragment that corresponds to a source-side tree fragment is identified via word alignment and mapping rules that are automatically learned. Then it is verified by checking the subtree list that is collected from large scal...

In this paper we address methodological issues in the evaluation of a projectionbased framework for dependency parsing in which annotations for a source language are transfered to a target language using word alignments in a parallel corpus. The projected trees then constitute the training data for a data-driven parser in the target language. We discuss two problems that arise in the evaluation...

We explored plasmon resonant nanorods of gold as a contrast agent for optical coherence tomography (OCT). Nanorod suspensions were generated through wet chemical synthesis and characterized with spectrophotometry, transmission electron microscopy, and OCT. Polyacrylamide-based phantoms were generated with appropriate scattering and anisotropy coefficients (30 cm(-1) and 0.89, respectively) to i...

Orogenic gold deposits have provided most of to humanity. These were formed by fluids carrying dissolved at temperatures 200–500 °C and crustal depths 4–12 km. The model involves mobilization as HS? complexes in aqueous solution buffered CO2, with precipitation following changes pH, redox activity (fO2), or H2S activity. In this contribution, the involvement carbonaceous organic matter is addre...

Automatic ontology matching is a hard problem. To address this problem many ontology matchers have evolved in the past several years. Consequently the evaluation of ontology matchers has become crucial in order to help improve a matcher’s performance. The evaluation frameworks used so far are limited to available pairs of ontologies in certain domains and require the reference alignments (i.e.,...

Electron String Ion Source (ESIS) “Krion-2” (JINR) is the first and now only ion source of such type in the world. ESIS is a sophisticated modification of Electron Beam Ion Source (EBIS) working in a reflex mode of operation under very specific conditions. Using the results of the research and the technology development the following main results were achieved in JINR with Krion-2 ESIS during r...

Anisotropic gold nanostructures with unique plasmonic properties, specifically the strong absorption of light in the near-infrared region (650-900 nm) due to the excitation of plasmon oscillations, have been widely employed as photothermal conversion agents (PTCAs) for cancer photothermal therapy (PTT). However, the reported PTCAs show suboptimal photothermal conversion efficiency (η), even gol...
