  2. Plus and minus signs - Wikipedia

    en.wikipedia.org/wiki/Plus_and_minus_signs

    While in J a negative number is denoted by an underscore, as in _5. In C and some other computer programming languages, two plus signs indicate the increment operator and two minus signs a decrement; the position of the operator before or after the variable indicates whether the new or old value is read from it. For example, if x equals 6, then ...

    Microsoft Excel is a spreadsheet editor developed by Microsoft for Windows, macOS, Android, iOS and iPadOS.It features calculation or computation capabilities, graphing tools, pivot tables, and a macro programming language called Visual Basic for Applications (VBA).

  4. Cyanobacteria - Wikipedia

    en.wikipedia.org/wiki/Cyanobacteria

    The classic taxonomic criterion has been the cell morphology and the plane of cell division. In Pleurocapsales, the cells have the ability to form internal spores (baeocytes). The rest of the sections include filamentous species. In Oscillatoriales, the cells are uniseriately arranged and do not form specialized cells (akinetes and heterocysts ...

  5. Negative number - Wikipedia

    en.wikipedia.org/wiki/Negative_number

    In mathematics, a negative number is the opposite of a positive real number. [1] Equivalently, a negative number is a real number that is less than zero. Negative numbers are often used to represent the magnitude of a loss or deficiency. A debt that is owed may be thought of as a negative asset.

    en.wikipedia.org/wiki/List_of_Red_Lists

    This list is of Red Lists, Red Data Books, and related initiatives that assess and document the extinction risk of species, whether on an international or more local level (regional Red Lists). The IUCN has published a set of Guidelines for Application of the IUCN Red List Criteria at Regional and National Levels and at least 113 countries have ...

  7. Bacterial capsule - Wikipedia

    en.wikipedia.org/wiki/Bacterial_capsule

    The outer red layer in this diagram is the capsule, which is distinct from the cell envelope. This bacterium is gram-positive, as its cell envelope comprises a single cell membrane (orange) and a thick peptidoglycan-containing cell wall (purple). The bacterial capsule is a large structure common to many bacteria. [1]

  8. Cell lists - Wikipedia

    The pairwise interactions for a single particle can be computed by a) computing the interaction to all other particles or b) by dividing the domain into cells with an edge length of at least the cut-off radius of the interaction potential and computing the interaction between the particle and all particles in the same (red) and in the adjacent (green) cells.

  9. Table of standard reduction potentials for half-reactions ...

    en.wikipedia.org/wiki/Table_of_standard...

    When an oxidizer (Ox) accepts a number z of electrons ( e −) to be converted in its reduced form (Red), the half-reaction is expressed as: Ox + z e − → Red. The reaction quotient (Q r) is the ratio of the chemical activity (a i) of the reduced form (the reductant, a Red) to the activity of the oxidized form (the oxidant, a ox).
