https://en.wikipedia.org/wiki/Von%20Neumann%20stability%20analysis | In numerical analysis, von Neumann stability analysis (also known as Fourier stability analysis) is a procedure used to check the stability of finite difference schemes as applied to linear partial differential equations. The analysis is based on the Fourier decomposition of numerical error and was developed at Los Ala... |
https://en.wikipedia.org/wiki/Tri-tet%20oscillator | A tri-tet oscillator is a crystal-controlled vacuum tube electronic oscillator circuit. It is a type of electron-coupled oscillator (ECO), which uses a tetrode or pentode tube.
The tri-tet was introduced by James J. Lamb in the June 1933 issue of QST magazine.
In an ECO, the screen grid acts as a plate for the triod... |
https://en.wikipedia.org/wiki/Ba%20space | In mathematics, the ba space of an algebra of sets is the Banach space consisting of all bounded and finitely additive signed measures on . The norm is defined as the variation, that is
If Σ is a sigma-algebra, then the space is defined as the subset of consisting of countably additive measures. The notation ba i... |
https://en.wikipedia.org/wiki/Restricted%20open-shell%20Hartree%E2%80%93Fock | Restricted open-shell Hartree–Fock (ROHF) is a variant of Hartree–Fock method for open shell molecules. It uses doubly occupied molecular orbitals as far as possible and then singly occupied orbitals for the unpaired electrons. This is the simple picture for open shell molecules but it is difficult to implement.

https://en.wikipedia.org/wiki/Four-center%20two-electron%20bond | A 4-center 2-electron (4c–2e) bond is a type of chemical bond in which four atoms share two electrons in bonding, with a net bond order of . This type of bonding differs from the usual covalent bond, which involves two atoms sharing two electrons (2c–2e bonding).
Four-center two-electron bonding is postulated in certa... |
https://en.wikipedia.org/wiki/Marginal%20sulcus | In neuroanatomy, the marginal sulcus (margin of the cingulate sulcus) is a sulcus (crevice) that may be considered the termination of the cingulate sulcus. It separates the paracentral lobule anteriorly and the precuneus posteriorly.
