  2. Matrix (chemical analysis) - Wikipedia

    en.wikipedia.org/wiki/Matrix_(chemical_analysis)

    A matrix effect value of less than 100 indicates suppression, while a value larger than 100 is a sign of matrix enhancement. An alternative definition of matrix effect utilizes the formula: M E = 100 ( A ( e x t r a c t ) A ( s t a n d a r d ) ) − 100 {\displaystyle ME=100\left({\frac {A(extract)}{A(standard)}}\right)-100}

  3. Petersen matrix - Wikipedia

    en.wikipedia.org/wiki/Petersen_matrix

    The Petersen matrix is a comprehensive description of systems of biochemical reactions used to model reactors for pollution control (engineered decomposition) as well as in environmental systems. It has as many columns as the number of relevant involved components ( chemicals , pollutants , biomasses , gases ) and as many rows as the number of ...

  4. Transfer-matrix method (statistical mechanics) - Wikipedia

    en.wikipedia.org/wiki/Transfer-matrix_method...

    The transfer-matrix method is used when the total system can be broken into a sequence of subsystems that interact only with adjacent subsystems. For example, a three-dimensional cubical lattice of spins in an Ising model can be decomposed into a sequence of two-dimensional planar lattices of spins that interact only adjacently.

  5. Design matrix - Wikipedia

    en.wikipedia.org/wiki/Design_matrix

    The design matrix has dimension n-by-p, where n is the number of samples observed, and p is the number of variables measured in all samples. [4] [5]In this representation different rows typically represent different repetitions of an experiment, while columns represent different types of data (say, the results from particular probes).

  6. Master equation - Wikipedia

    en.wikipedia.org/wiki/Master_equation

    Stochastic chemical kinetics provide yet another example of the use of the master equation. A master equation may be used to model a set of chemical reactions when the number of molecules of one or more species is small (of the order of 100 or 1000 molecules). [ 4 ]

  7. Matrix model - Wikipedia

    en.wikipedia.org/wiki/Matrix_model

    a model using a matrix in mathematics; Matrix models (physics), a simplified quantum gauge theory and related mathematical techniques used to study a wide range of topics in theoretical and mathematical physics; Matrix theory (physics), a quantum mechanical model; Matrix population models, a type of population model that uses matrix algebra

  8. Matrigel - Wikipedia

    en.wikipedia.org/wiki/Matrigel

    Matrigel is the trade name for the solubilized basement membrane matrix secreted by Engelbreth-Holm-Swarm (EHS) mouse sarcoma cells produced by Corning Life Sciences. . Matrigel resembles the laminin/collagen IV-rich basement membrane extracellular environment found in many tissues and is used by cell biologists as a substrate (basement membrane matrix) for culturi

  9. Matrix (composite) - Wikipedia

    en.wikipedia.org/wiki/Matrix_(composite)

    Asphalt concrete, which is often used in the construction of roads, has a matrix called bitumen. Mud (wattle and daub) has observed considerable use. [6] Epoxy is utilized as a structural glue or structural matrix material in the aerospace industry. Epoxy resin is, when cured, nearly transparent.
