Absorption spectroscopy has been widely used in gemstone societies as it enables the identification of origin and post-treatment gemstones a non-destructive way. The infrared (IR) range is critical for studies such corundum, emerald, diamond. Regarding corundum sample, absorption peaks related to -OH bond could be an index heat-treatment detection, different types inclusions identified by analy...

Methods 19 patients (m/f-16/3, mean age 59,6± 2,0 years) with history of myocardial infarction ( >1 year) were prospectively enrolled in the study. The CCTA protocol consisted of prospectively gated CTA and DECT. DECT was performed with single-tube 64-row CT in gemstone spectral imaging (GSI) mode with 8 min delay after contrast media injection. Using a 4-point transmurality scale CCTA images w...

In this paper we address the problem of incrementally maintaining objectoriented database (OODB) views formed using path queries. We demonstrate that traditional index organizations, designed for query support, are not well suited for this task. As a solution, we introduce a new Satisfiability Indicating Multi-Index (SMX) organization, which maintains partial information indicating whether or n...

A large amount of human genome data has been collected and efficient techniques for handling the data and for building and testing biological hypotheses are needed. We developed an object-oriented database system with rule-based query interface for genomic computation. The database is constructed on a commercially available object-oriented database system Gemstone and contains GenBank entries a...
