Calpains constitute the C2 family of protease clan CA in the MEROPS database. The calpain proteolytic system includes the calpain... |
https://en.wikipedia.org/wiki/Inward-rectifier%20potassium%20channel | Inward-rectifier potassium channels (Kir, IRK) are a specific lipid-gated subset of potassium channels. To date, seven subfamilies have been identified in various mammalian cell types, plants, and bacteria. They are activated by phosphatidylinositol 4,5-bisphosphate (PIP2). The malfunction of the channels has been impl... |
https://en.wikipedia.org/wiki/Minichamps | Minichamps is a die-cast model car brand founded as Paul's Model Art GmbH in 1990 in Aachen, Germany, best known for its 1:18, 1:43 and 1:64 scale models. The company grew out of the Danhausen trade catalog of miniature vehicles and specially made Danhausen diecast releases during the 1970s.

https://en.wikipedia.org/wiki/Majorization | In mathematics, majorization is a preorder on vectors of real numbers. Let denote the -th largest element of the vector . Given , we say that weakly majorizes (or dominates) from below (or equivalently, we say that is weakly majorized (or dominated) by from below) denoted as if for all . If in addition , we say ... |
https://en.wikipedia.org/wiki/String%20cosmology | String cosmology is a relatively new field that tries to apply equations of string theory to solve the questions of early cosmology. A related area of study is brane cosmology.
Overview
This approach can be dated back to a paper by Gabriele Veneziano that shows how an inflationary cosmological model can be obtained f... |
https://en.wikipedia.org/wiki/Fermi%E2%80%93Pasta%E2%80%93Ulam%E2%80%93Tsingou%20problem | In physics, the Fermi–Pasta–Ulam–Tsingou (FPUT) problem or formerly the Fermi–Pasta–Ulam problem was the apparent paradox in chaos theory that many complicated enough physical systems exhibited almost exactly periodic behavior – called Fermi–Pasta–Ulam–Tsingou recurrence (or Fermi–Pasta–Ulam recurrence) – instead of th... |
https://en.wikipedia.org/wiki/Schr%C3%B6dinger%20functional | In mathematical physics, some approaches to quantum field theory are more popular than others. For historical reasons, the Schrödinger representation is less favored than Fock space methods. In the early days of quantum field theory, maintaining symmetries such as Lorentz invariance, displaying them manifestly, and pr... |
https://en.wikipedia.org/wiki/Staggered%20fermion | In lattice field theory, staggered fermions (also known as Kogut–Susskind fermions) are a fermion discretization that reduces the number of fermion doublers from sixteen to four. They are one of the fastest lattice fermions when it comes to simulations and they also possess some nice features such as a remnant chiral s... |
https://en.wikipedia.org/wiki/Hamiltonian%20lattice%20gauge%20theory | In physics, Hamiltonian lattice gauge theory is a calculational approach to gauge theory and a special case of lattice gauge theory in which the space is discretized but time is not. The Hamiltonian is then re-expressed as a function of degrees of freedom defined on a d-dimensional lattice.
Following Wilson, the spati... |
https://en.wikipedia.org/wiki/Linearized%20gravity | In the theory of general relativity, linearized gravity is the application of perturbation theory to the metric tensor that describes the geometry of spacetime. As a consequence, linearized gravity is an effective method for modeling the effects of gravity when the gravitational field is weak. The usage of linearized g... |
https://en.wikipedia.org/wiki/Fusion%20rules | In mathematics and theoretical physics, fusion rules are rules that determine the exact decomposition of the tensor product of two representations of a group into a direct sum of irreducible representations. The term is often used in the context of two-dimensional conformal field theory where the relevant group is gene... |
https://en.wikipedia.org/wiki/Conformal%20family | In theoretical physics, a conformal family is an irreducible representation of the Virasoro algebra. In most cases, it is uniquely determined by its primary field or the highest weight vector. The family contains all of its descendant fields. |
https://en.wikipedia.org/wiki/Ischemic%20cascade | The ischemic (ischaemic) cascade is a series of biochemical reactions that are initiated in the brain and other aerobic tissues after seconds to minutes of ischemia (inadequate blood supply). This is typically secondary to stroke, injury, or cardiac arrest due to heart attack. Most ischemic neurons that die do so due t... |
