It is characterized by a linear coupling between the system's magnetic polarization and mechanical strain. In a piezomagnetic material, one may induce a spontaneous magnetic moment by applying mechanical stress, or a physical ... |
https://en.wikipedia.org/wiki/Airline%20reservations%20system | Airline reservation systems (ARS) are systems that allow an airline to sell their inventory (seats). It contains information on schedules and fares and contains a database of reservations (or passenger name records) and of tickets issued (if applicable). ARSs are part of passenger service systems (PSS), which are appli... |
https://en.wikipedia.org/wiki/Antigenic%20escape | Antigenic escape, immune escape, immune evasion or escape mutation occurs when the immune system of a host, especially of a human being, is unable to respond to an infectious agent: the host's immune system is no longer able to recognize and eliminate a pathogen, such as a virus. This process can occur in a number of d... |
https://en.wikipedia.org/wiki/Page%20attribute%20table | The page attribute table (PAT) is a processor supplementary capability extension to the page table format of certain x86 and x86-64 microprocessors. Like memory type range registers (MTRRs), they allow for fine-grained control over how areas of memory are cached, and are a companion feature to the MTRRs.
Unlike MTRRs... |
https://en.wikipedia.org/wiki/Autonetics%20Recomp%20II | The Autonetics RECOMP II was a computer first introduced in 1958. It was made by the Autonetics division of North American Aviation.
It was attached to a desk that housed the input/output devices. Its desk integration made it a hands-on small system intended for the scientific and engineering computing market. The co... |
https://en.wikipedia.org/wiki/Epsilon%20calculus | In logic, Hilbert's epsilon calculus is an extension of a formal language by the epsilon operator, where the epsilon operator substitutes for quantifiers in that language as a method leading to a proof of consistency for the extended formal language. The epsilon operator and epsilon substitution method are typically a... |
https://en.wikipedia.org/wiki/Volvelle | A volvelle or wheel chart is a type of slide chart, a paper construction with rotating parts. It is considered an early example of a paper analog computer. Volvelles have been produced to accommodate organization and calculation in many diverse subjects. Early examples of volvelles are found in the pages of astronomy b... |
https://en.wikipedia.org/wiki/Jordan%20and%20Einstein%20frames | The Lagrangian in scalar-tensor theory can be expressed in the Jordan frame in which the scalar field or some function of it multiplies the Ricci scalar, or in the Einstein frame in which Ricci scalar is not multiplied by the scalar field. There exist various transformations between these frames. Despite the fact th... |
https://en.wikipedia.org/wiki/Limit%20comparison%20test | In mathematics, the limit comparison test (LCT) (in contrast with the related direct comparison test) is a method of testing for the convergence of an infinite series.
Statement
Suppose that we have two series and with for all .
Then if with , then either both series converge or both series diverge.
Proof

https://en.wikipedia.org/wiki/Topological%20derivative | The topological derivative is, conceptually, a derivative of a shape functional with respect to infinitesimal changes in its topology, such as adding an infinitesimal hole or crack. When used in higher dimensions than one, the term topological gradient is also used to name the first-order term of the topological asympt... |
https://en.wikipedia.org/wiki/Less-than%20sign | The less-than sign is a mathematical symbol that denotes an inequality between two values. The widely adopted form of two equal-length strokes connecting in an acute angle at the left, , has been found in documents dated as far back as the 1560s. In mathematical writing, the less-than sign is typically placed between t... |
