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 ...
Donut Media was founded in 2015 by Matt Levin, a former product head at AwesomenessTV, Ben Conrad and Nick Moceri. [1] The channel's first video was about the 24 Hours of LeMons. [2] It achieved early viral success with its 2016 video Two Grannies, One Lamborghini, which for many years was the channel's most-viewed video.
Randy's Donuts is a bakery and a landmark building in Inglewood, California which is near Los Angeles International Airport. It is built in a style that dates to a period in the early 20th century that saw a proliferation of programmatic architecture throughout Southern California. This style had its heyday from the mid-1920s to the mid-1930s.
In logic, a set of symbols is commonly used to express logical representation. The following table lists many common symbols, together with their name, how they should be read out loud, and the related field of mathematics.
APL is going to execute from right-to-left. Step 1 {of topmost APL code entered at left}) 4-5 = -1. Step 2) 3 times -1 = -3. Step 3) Take the floor or lower of 2 and -3 = -3. Step 4) Divide 1 by -3 = -0.3333333333 = final result. An operator may have function or data operands and evaluate to a dyadic or monadic function.
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 ...
Scope resolution operator. In computer programming, scope is an enclosing context where values and expressions are associated. The scope resolution operator helps to identify and specify the context to which an identifier refers, particularly by specifying a namespace or class.
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.}
Superoperator. In physics, a superoperator is a linear operator acting on a vector space of linear operators. [1] Sometimes the term refers more specially to a completely positive map which also preserves or does not increase the trace of its argument. This specialized meaning is used extensively in the field of quantum computing, especially ...
In November 2020, Afilias was acquired by the domain name registry operator Donuts. Managed TLDs. Identity Digital / Donuts is either the ICANN-approved sponsor organization or owns controlling interest in the ICANN-approved sponsor organization for 264 top-level domains, approximately 30% of all generally-available TLDs.
