    In a database, a table is a collection of related data organized in table format; consisting of columns and rows.. In relational databases, and flat file databases, a table is a set of data elements (values) using a model of vertical columns (identifiable by name) and horizontal rows, the cell being the unit where a row and column intersect.

    en.wikipedia.org/wiki/Row_and_column_spaces

    The row space is defined similarly. The row space and the column space of a matrix A are sometimes denoted as C(A T) and C(A) respectively. [2] This article considers matrices of real numbers. The row and column spaces are subspaces of the real spaces and respectively. [3]

  4. Cell type - Wikipedia

    en.wikipedia.org/wiki/Cell_type

    A cell type is a classification used to identify cells that share morphological or phenotypical features. [1] A multicellular organism may contain cells of a number of widely differing and specialized cell types, such as muscle cells and skin cells, that differ both in appearance and function yet have identical genomic sequences.

    en.wikipedia.org/wiki/Luria–Delbrück_experiment

    A small number of cells are used to inoculate parallel cultures in a non-selective medium. [11] The cultures are grown to saturation to obtain equal cell densities. The cells are plated onto selective media to obtain the number of mutants (r). Dilutions are plated onto rich medium to calculate the total number of viable cells ( N t). The number ...

  6. List of types of solar cells - Wikipedia

    en.wikipedia.org/wiki/List_of_types_of_solar_cells

    A solar cell (also called photovoltaic cell or photoelectric cell) is a solid state electrical device that converts the energy of light directly into electricity by the photovoltaic effect, which is a physical and chemical phenomenon. It is a form of photoelectric cell, defined as a device whose electrical characteristics, such as current ...

  7. Prospect theory - Wikipedia

    en.wikipedia.org/wiki/Prospect_theory

    This "reference point" is different for each person and relative to their individual situation. Thus, rather than making decisions like a rational agent (i.e using expected utility theory and choosing the maximum value), decisions are made in relativity not in absolutes. [4] [5] Consider two scenarios;

  8. Epithelium - Wikipedia

    en.wikipedia.org/wiki/Epithelium

    By layer, epithelium is classed as either simple epithelium, only one cell thick (unilayered), or stratified epithelium having two or more cells in thickness, or multi-layered – as stratified squamous epithelium, stratified cuboidal epithelium, and stratified columnar epithelium, [8]: 94, 97 and both types of layering can be made up of any of ...

  9. Apophenia - Wikipedia

    en.wikipedia.org/wiki/Apophenia

    Apophenia (/ æ p oʊ ˈ f iː n i ə /) is the tendency to perceive meaningful connections between unrelated things. [1]The term (German: Apophänie from the Greek verb: ἀποφαίνειν, romanized: apophaínein) was coined by psychiatrist Klaus Conrad in his 1958 publication on the beginning stages of schizophrenia. [2]
