Massive amount of data that are geo-tagged and associated with text information are being generated at an unprecedented scale. These geo-textual data cover a wide range of topics. Users are interested in receiving up-to-date geo-textual objects (e.g., geo-tagged Tweets) such that their locations meet users’ need and their texts are interesting to users. For example, a user may want to be update...

The objective of this study was to evaluate the cytotoxic activity of rosemary (REO, Rosmarinus officinalis L.), turmeric (CEO, Curcuma longa L.), and ginger (GEO, Zingiber officinale R.) essential oils in HeLa cells. Cytotoxicity tests were performed in vitro, using tetrazolium (MTT) and neutral red assays for evaluation of antiproliferative activity by different mechanisms, trypan blue assay ...

Space capabilities derived from the geosynchronous orbit (GEO) are unique and difficult to replicate in other orbital regions. Therefore, a premium is placed on the preservation of the GEO. An accurate understanding of the efficacy of debris mitigation measures is essential. Evidence seems to indicate retired systems in disposal orbits are shedding materials that transit the GEO region. In addi...

In these days, geo-spatial technologies, as components in geo-web, according to extension of web 2.0 or more paradigms are diversified and emerged: software as a service, asynchronous particle update, mashup, open sources, rich user experiences, collaborate tagging, and structured information. These are closely related and linked to each other, so as to design and implementation stages for a gi...

AIM: To explore hub genes for glaucoma based on bioinformatics analysis and an experimental model verification. METHODS: In the Gene Expression Omnibus (GEO) database, GSE25812 GSE26299 datasets were selected to analyze differentially expressed (DEGs) by GEO2R tool. Through analysis, 9 identified. Receiver operating characteristic (ROC) curves principal component (PCA) performed verify whether ...

Currently, Geo-data-mining and knowledge discovering, new kernel of GIS spatial analysis study, which help breaking theoretic limitation of Geo-expert system and revealing an innovative research roadmap for new era Geo-information sciences, represent latest researching trend of GIS. Various research communities have tried to applying or revising mathematic tools as probability theory, spatial s...
