Current barriers hindering data-driven discoveries in deep-time Earth (DE) include: substantial volumes of DE data are not digitized; many databases do adhere to FAIR (findable, accessible, interoperable and reusable) principles; we lack a systematic knowledge graph for DE; existing geographically heterogeneous; significant fraction is open-access formats; tailored tools needed. These challenges motivate the Deep-Time Digital (DDE) program initiated by International Union Geological Sciences...

MicroRNA (miRNA or miR) inhibition of oncogenic related pathways has been shown to be a promising therapeutic approach for cancer. SIRT1 might promoter factor on tumorigenesis hepatocellular carcinoma (HCC). However, the mechanism is unknown. We investigated whether miRNAs regulate and its downstream SREBP-lipogenesis-cholesterogenesis metabolic pathway in hepatoma cells. Human cells were transfected with miR-449 mimics inhibitors, effects cell proliferation was assessed. identified miRNAs,...

Background: 3,4-dihydroxycinnamic acid and its derivatives exhibit numerous biologic activities. Such activities have not previously been reported for 3,5-dihydroxycinnamic derivatives. In this study, ten of 3,5- dihydroxycinnamic were synthesized their anti-inflammatory tested in 12-O-tetradecanoylphorbol 13-acetate-induced mouse ear edema. Molecular biological studies shed lights on mechanism. Methods: Anti-inflammatory new edema, mechanism was studied by ELISA, real-time RT-PCR, MPO assay...

The Hurst exponent is a significant indicator for characterizing the self-similarity and long-term memory properties of time sequences. It has wide applications in physics, technologies, engineering, mathematics, statistics, economics, psychology so on. Currently, available methods estimating sequences can be divided into different categories: time-domain spectrum-domain based on representation sequence, linear regression Bayesian parameter estimation methods. Although various are discussed...

Zernike radial polynomials (ZRP) play a significant role in application areas such as optics design, imaging systems, and image processing systems. Currently, there are two kinds of numerical schemes for computing the ZRP automatically with computer programs: one is based on definition which factorial operations may lead to overflow problem high order derivatives troublesome, other recursion either unstable or computational complexity. In this paper, our emphasis focused exploring balanced...

Kuiper's $V_n$ statistic, a measure for comparing the difference of ideal distribution and empirical distribution, is great significance in goodness-of-fit test. However, formulae computing cumulative function, false positive probability upper tail quantile $V_n$can not be applied to case small sample capacity $n$ since approximation error $\mathcal{O}(n^{-1})$. In this work, our contributions lie three perspectives: firstly reduced $\mathcal{O}(n^{-(k+1)/2})$ where $k$ expansion order with...
