Introduction . Keywords, reflecting the main content of article, play an extremely important role in search for scientific papers databases. Together with title and abstract, keywords provide primary information about study. Selecting extracting effective is a time-consuming process, so its optimization requires further studying. Purpose. The article aimed at acquainting authors journal methods...

In the paper, we propose an intelligent meta-search engine that bases on user’s query keyword(s) to find the extended keywords and more related websites. Instead of listing a lot of candidate websites waiting for users to search, the extended related keywords and more related documents appeared in the explorer window are derived from the proposed method. In case a user is not satisfied with the...

Many cities in the Global South are structurally different from Northern, particularly American, on which much of urban sociology’s conceptual apparatus has been based. Thus, depicting them terms a standard vocabulary risks imposing an inappropriate way seeing. We need that is able to accommodate their experience. This special issue contributes work building vocabulary. select five keywords soc...

[1] In situ crystallography based on diamond anvil cells have been extended to the multimegabar regime. Temperatures in these experiments have crossed the 2500 K mark. Yet, current high pressure-temperature (PT) standards of calibration produce uncertainties that inhibit clear conclusions about phenomena of importance to planetary processes, e.g., the postperovskite transition in Earth’s mantle...

A new thermodynamically self-consistent (TSC) method, based on the quasi-harmonic approximation (QHA), is used to obtain the Debye temperatures of LiFePO4 (LFP) and FePO4 (FP) from available experimental specific heat capacities for a wide temperature range. The calculated Debye temperatures show an interesting critical and peculiar behavior so that a steep increase in the Debye temperatures is...

There is a need to develop more intelligent means for handling text in applications such as information retrieval, information filtering, and message classification. This raises the need for mechanisms for ascertaining what an item of text is about. Even though natural language processing offers the best results, it is not always viable. A less accurate, but more viable alternative, is to reaso...
