    ON NEWTON-RAPHSON METHOD

    Get PDF
    Recent versions of the well-known Newton-Raphson method for solving algebraic equations are presented. First of these is the method given by J. H. He in 2003. He reduces the problem to solving a second degree polynomial equation. However He’s method is not applicable when this equation has complex roots. In 2008, D. Wei, J. Wu and M. Mei eliminated this deficiency, obtaining a third order polynomial equation, which has always a real root. First of the authors of present paper obtained higher order polynomial equations, which for orders 2 and 3 are reduced to equations given by He and respectively by Wei-Wu-Mei, with much improved form. In this paper, we present these methods. An example is given.newton-raphson

    DAOISM AS CRITICAL THEORY

    Get PDF
    Classical philosophical Daoism as it is expressed in the Dao-De-Jing and the Zhuang-Zi is often interpreted as lacking a capacity for critique and resistance. Since these capacities are taken to be central components of Enlightenment reason and action, it would follow that Daoism is incompatible with Enlightenment. This interpretation is being refuted by way of developing a constructive dialogue between the enlightenment traditions of critical theory and recent philosophy of action from a Daoist perspective. Daoism\u27s normative naturalism does neither rest on a primitivist call for a return to the past, nor does it suggest future-directed activism. By way of reconstructing its descriptive, explanatory and emancipatory dimensions, it is shown that Daoism constitutes an alternative form of critical theory. In contrast to future-directed purposive action or blind rule-following, Daoism\u27s key normative concept of wu-wei emphasizes effortless non-calculative responsiveness in the present. Drawing on recent insights in the philosophy of action, a reconstruction of wu-wei allows to conceive of a promising form of emancipatory agency

    Genomic organization and chromosomal localization of the murine 2 P domain potassium channel gene Kcnk8: conservation of gene structure in 2 P domain potassium channels.

    A 2 P domain potassium channel expressed in eye, lung, and stomach, Kcnk8, has recently been identified. To initiate further biochemical and genetic studies of this channel, we assembled the murine Kcnk8 cDNA sequence, characterized the genomic structure of the Kcnk8 gene, determined its chromosomal localization, and analyzed its activity in a Xenopus laevis oocyte expression system. The composite cDNA has an open reading frame of 1029 bp and encodes a protein of 343 amino acids with a predicted molecular mass of 36 kDa. Structure analyses predict 2 P domains and four potential transmembrane helices with a potential single EF-hand motif and four potential SH3-binding motifs in the COOH-terminus. Cloning of the Kcnk8 chromosomal gene revealed that it is composed of three exons distributed over 4 kb of genomic DNA. Genome database searching revealed that one of the intron/exon boundaries identified in Kcnk8 is present in other mammalian 2 P domain potassium channels genes and many C. elegans 2P domain potassium channel genes, revealing evolutionary conservation of gene structure. Using fluorescence in situ hybridization, the murine Kcnk8 gene was mapped to chromosome 19, 2B, the locus of the murine dancer phenotype, and syntenic to 11q11-11q13, the location of the human homologue. No significant currents were generated in a Xenopus laevis oocyte expression system using the composite Kcnk8 cDNA sequence, suggesting, like many potassium channels, additional channel subunits, modulator substances, or cellular chaperones are required for channel function
