  2. Fold change - Wikipedia

    en.wikipedia.org/wiki/Fold_change

    However, log-ratios are often used for analysis and visualization of fold changes. The logarithm to base 2 is most commonly used, [ 8 ] [ 9 ] as it is easy to interpret, e.g. a doubling in the original scaling is equal to a log 2 fold change of 1, a quadrupling is equal to a log 2 fold change of 2 and so on.

  3. Skyrim modding - Wikipedia

    en.wikipedia.org/wiki/Skyrim_modding

    Skyrim is noted to have an active adult modding scene centered around the website LoversLab, a 1.5 million member "massive sex mod community". Its owner, Ashal, created a mod template for the game known as SexLab that enabled the creation of adult-themed mods by providing a "foundation of thousands of animations and basic game functions".

  4. Logarithm - Wikipedia

    en.wikipedia.org/wiki/Logarithm

    The graph of the logarithm base 2 crosses the x-axis at x = 1 and passes through the points (2, 1), (4, 2), and (8, 3), depicting, e.g., log 2 (8) = 3 and 2 3 = 8. The graph gets arbitrarily close to the y-axis, but does not meet it. Addition, multiplication, and exponentiation are three of the most fundamental arithmetic operations.

  5. List of logarithmic identities - Wikipedia

    en.wikipedia.org/wiki/List_of_logarithmic_identities

    The multiple valued version of log(z) is a set, but it is easier to write it without braces and using it in formulas follows obvious rules. log(z) is the set of complex numbers v which satisfy e v = z; arg(z) is the set of possible values of the arg function applied to z. When k is any integer:

  6. Blend modes - Wikipedia

    For b=0, one still gets γ=2, for b=0.5 one gets γ=1, for b=1 one gets γ=0.5, but it is not a linear interpolation between these 3 images. The formula specified by recent W3C drafts [ 3 ] for SVG and Canvas is mathematically equivalent to the Photoshop formula with a small variation where b≥0.5 and a≤0.25:

    The logarithm in the table, however, is of that sine value divided by 10,000,000. [1]: p. 19 The logarithm is again presented as an integer with an implied denominator of 10,000,000. The table consists of 45 pairs of facing pages. Each pair is labeled at the top with an angle, from 0 to 44 degrees, and at the bottom from 90 to 45 degrees.

  8. 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".
