https://en.wikipedia.org/wiki/L1%20%28protein%29 | L1, also known as L1CAM, is a transmembrane protein member of the L1 protein family, encoded by the L1CAM gene. This protein, of 200-220 kDa, is a neuronal cell adhesion molecule with a strong implication in cell migration, adhesion, neurite outgrowth, myelination and neuronal differentiation. It also plays a key role ... |

https://en.wikipedia.org/wiki/Random%20matrix | In probability theory and mathematical physics, a random matrix is a matrix-valued random variable—that is, a matrix in which some or all elements are random variables. Many important properties of physical systems can be represented mathematically as matrix problems. For example, the thermal conductivity of a lattice ... |
https://en.wikipedia.org/wiki/Viral%20replication | Viral replication is the formation of biological viruses during the infection process in the target host cells. Viruses must first get into the cell before viral replication can occur. Through the generation of abundant copies of its genome and packaging these copies, the virus continues infecting new hosts. Replica... |
https://en.wikipedia.org/wiki/Procedural%20surface | In computer graphics, a procedural surface is a representation of a surface as a mathematical implicit equation, rather than an explicit representation.
An explicit representation, for example, describes a line as the straight segment going through two given points. A procedural surface is one which is defined as a pr... |

https://en.wikipedia.org/wiki/Isotopic%20labeling | Isotopic labeling (or isotopic labelling) is a technique used to track the passage of an isotope (an atom with a detectable variation in neutron count) through a reaction, metabolic pathway, or cell. The reactant is 'labeled' by replacing specific atoms by their isotope. The reactant is then allowed to undergo the reac... |
https://en.wikipedia.org/wiki/Michael%20Aschbacher | Michael George Aschbacher (born April 8, 1944) is an American mathematician best known for his work on finite groups. He was a leading figure in the completion of the classification of finite simple groups in the 1970s and 1980s. It later turned out that the classification was incomplete, because the case of quasithin ... |
