Old-fashioned doughnuts – cinnamon sugar (left), chocolate glazed (centre top) and maple glazed (right). Shape shown is typical of commercially available buttermilk donuts. The old-fashioned doughnut is a term used for a variety of cake doughnut prepared in the shape of a ring with a cracked surface and tapered edges around it. [1]
d'Alembert operator. In special relativity, electromagnetism and wave theory, the d'Alembert operator (denoted by a box: ), also called the d'Alembertian, wave operator, box operator or sometimes quabla operator [1] ( cf. nabla symbol) is the Laplace operator of Minkowski space. The operator is named after French mathematician and physicist ...

The Arrows block (U+2190–U+21FF) contains line, curve, and semicircle arrows and arrow-like operators. The math subset of this block is U+2190–U+21A7, U+21A9–U+21AE, U+21B0–U+21B1, U+21B6–U+21B7, U+21BC–U+21DB, U+21DD, U+21E4–U+21E5, U+21F4–U+21FF.
ACP-131 [1] is the controlling publication for the listing of Q codes and Z codes. It is published and revised from time to time by the Combined Communications Electronics Board (CCEB) countries: Australia, New Zealand, Canada, United Kingdom, and United States. When the meanings of the codes contained in ACP-131 are translated into various ...
Since the stabilizer operators of the toric code are quasilocal, acting only on spins located near each other on a two-dimensional lattice, it is not unrealistic to define the following Hamiltonian, H T C = − J ∑ v A v − J ∑ p B p , J > 0. {\displaystyle H_{\rm {TC}}=-J\sum _{v}A_{v}-J\sum _{p}B_{p},\,\,\,J>0.}
Unique, fixed customer codes were used by Boeing Commercial Airplanes to denote the original customer for airframes produced as part of Boeing's 7x7 family of commercial aircraft from 1956 (except for the Boeing 787 Dreamliner), starting with the introduction of the 707, followed by the Boeing 717, Boeing 727, Boeing 737, Boeing 747, Boeing 757, Boeing 767 and Boeing 777 up until 2016.

In quantum mechanics, the exchange operator , also known as permutation operator, is a quantum mechanical operator that acts on states in Fock space. The exchange operator acts by switching the labels on any two identical particles described by the joint position quantum state . [1]
