    Model test study on natural frequency evolution and early warning of reservoir landslides under water level fluctuations

    Reservoir water fluctuation is the key factor affecting the stability of reservoir landslides. Existing research on the evolution of landslides under cyclic reservoir water fluctuations is limited. However, fu...

    Nichols algebras over weak Hopf algebras

    In this paper, we study a Yetter-Drinfeld module V over a weak Hopf algebra ℍ. Although the category of all left ℍ-modules is not a braided tensor category, we can define a Yetter-Drinfeld module. Using this Yett...

    On the ratio of intercellular to ambient CO2 (c i/c a) derived from ecosystem flux

    The ratio of intercellular to ambient CO2 concentrations (c i/c a) plays a key role in ecophysiology, micrometeorology, and global climatic change. However, systema...

    Wnt/β-catenin signaling inhibits FBXW7 expression by upregulation of microRNA-770 in hepatocellular carcinoma

    FBXW7 (F-box and WD repeat domain-containing 7) is the F-box protein component of a Skp1–Cul1–F-box protein–type (SCF-type) ubiquitin ligase. Previous studies have shown that FBXW7 serves as a tumor suppressor...

    The extension of a quantized Borcherds superalgebra by a Hopf algebra

    A two-parameter quantum group is obtained from the usual envelo** algebra by adding two commutative grouplike elements. In this paper, we generalize this procession further by adding commutative grouplike el...

    Regulation of β-catenin transcription activity by leupaxin in hepatocellular carcinoma

    In human cancers, β-catenin is accumulated in the nucleus and activates mRNA transcription of many oncogenic genes, such as cyclin D1 and c-myc. However, the mechanism of β-catenin-mediated transcriptional act...
