    Introducing Fluctuation into Increasing Order of Symmetric Uncertainty for Consistency-Based Feature Selection

    In order to select correlated and relevant features in a feature selection, several filter methods adopt a symmetric uncertainty as one of the feature ranking measures. In this paper, we introduce a fluctuation i...

    Variation of geochemical environments associated with whale-fall biomass mineralization processes in the sediment during the mobile scavenger, enrichment opportunist, and sulfophilic stages

    The succession of faunal composition of a whale-fall community is believed to depend on the progress of decomposition of the whale carcass, which itself is dependent on microbial activity in the sediment aroun...

    Extracting Mutually Dependent Multisets

    In this paper, we extend mutually dependent patterns as itemsets introduced by Ma and Hellerstein (2001) to mutually dependent multisets allowing two or more occurrences of the same items. Then, by improving the ...

    A Compilation of the Stable Isotopic Compositions of Carbon, Nitrogen, and Sulfur in Soft Body Parts of Animals Collected from Deep-Sea Hydrothermal Vent and Methane Seep Fields: Variations in Energy Source and Importance of Subsurface Microbial Processes in the Sediment-Hosted Systems

    The stable isotopic signatures of biophilic elements, such as carbon, nitrogen, and sulfur, exhibited in animal soft body parts are excellent indicators for evaluating the pathways of energy and food sources. ...
