soil compaction has become a widespread problem in the world and it is considered as one of the main factors affecting land degradation in arid and semi-arid agricultural land. the aim of this study was to investigate the effects of soil compaction on soil carbon and nitrogen sequestration, physical (aggregate stability, saturated soil moisture content, bulk density, and porosity) and chemical ...

there are overwhelming reports and descriptions about celiac associated disorders. although there is a clear genetic association between celiac disease (cd) and some gastrointestinal disorders, there are controversial reports claiming an association between cd and helicobacter pylori (h. pylori) infection. different studies indicated the possible association between lymphocytic gastritis and bo...

In this paper, principles and existing feature selection methods for classifying and clustering data be introduced. To that end, categorizing frameworks for finding selected subsets, namely, search-based and non-search based procedures as well as evaluation criteria and data mining tasks are discussed. In the following, a platform is developed as an intermediate step toward developing an intell...

Background: In the current study, a hybrid feature selection approach involving filter and wrapper methods is applied to some bioscience databases with various records, attributes and classes; hence, this strategy enjoys the advantages of both methods such as fast execution, generality, and accuracy. The purpose is diagnosing of the disease status and estimating of the patient survival. Method...

feature geometry, which is a basic assumption in current phonology, is concerned with the notion that the features are not an unstructured set, but are arranged hierarchically into a constituent structure tree. according to evidences in different languages, various models have been set forth on feature geometry framework. exploring persian phonological data and digging up evidences accordingly,...
