    Varenicline, sold under the brand names Chantix and Champix among others, is a medication used for smoking cessation [5] [7] and for the treatment of dry eye syndrome. [6] [8] It is a nicotinic acetylcholine receptor partial agonist.

  3. Log amplifier - Wikipedia

    en.wikipedia.org/wiki/Log_amplifier

    And, diffusion currents in surface inversion layers and generation-recombination effects in space-charge regions cause a scale factor at low currents that varies (between 1 and 4) with current. [1] With inputs near 0 volts, log amps have a linear to law. But this non-logarithmic behavior itself is often lost in this device noise, which limits ...

  4. Common logarithm - Wikipedia

    en.wikipedia.org/wiki/Common_logarithm

    The mathematical notation for using the common logarithm is log(x), [4] log 10 (x), [5] or sometimes Log(x) with a capital L; [a] on calculators, it is printed as "log", but mathematicians usually mean natural logarithm (logarithm with base e ≈ 2.71828) rather than common logarithm when writing "log".

  6. Lupus anticoagulant - Wikipedia

    en.wikipedia.org/wiki/Lupus_anticoagulant

    A ratio of 1.2 is commonly used, such that a value <1.2 indicates the absence of a lupus anticoagulant, while a value >1.2 indicates the presence of a lupus anticoagulant. [19] Direct oral anticoagulants and vitamin K antagonists used to treat thrombosis can interfere with lupus anticoagulant assays and generate either false-positive or false ...

  8. x̅ and R chart - Wikipedia

    en.wikipedia.org/wiki/X̅_and_R_chart

    R = x max - x min. The normal distribution is the basis for the charts and requires the following assumptions: The quality characteristic to be monitored is adequately modeled by a normally distributed random variable; The parameters μ and σ for the random variable are the same for each unit and each unit is independent of its predecessors or ...

  9. Logarithm - Wikipedia

    en.wikipedia.org/wiki/Logarithm

    As an integral, ln(t) equals the area between the x-axis and the graph of the function 1/x, ranging from x = 1 to x = t. This is a consequence of the fundamental theorem of calculus and the fact that the derivative of ln(x) is 1/x. Product and power logarithm formulas can be derived from this definition. [41]
