https://en.wikipedia.org/wiki/Selection%20theorem | In functional analysis, a branch of mathematics, a selection theorem is a theorem that guarantees the existence of a single-valued selection function from a given set-valued map. There are various selection theorems, and they are important in the theories of differential inclusions, optimal control, and mathematical ec... |

https://en.wikipedia.org/wiki/Breather%20surface | In differential geometry, a breather surface is a one-parameter family of mathematical surfaces which correspond to breather solutions of the sine-Gordon equation, a differential equation appearing in theoretical physics. The surfaces have the remarkable property that they have constant curvature , where the curvature ... |
https://en.wikipedia.org/wiki/Cash%20conversion%20cycle | In management accounting, the Cash conversion cycle (CCC) measures how long a firm will be deprived of cash if it increases its investment in inventory in order to expand customer sales. It is thus a measure of the liquidity risk entailed by growth. However, shortening the CCC creates its own risks: while a firm could ... |
https://en.wikipedia.org/wiki/Coherence%20bandwidth | Coherence bandwidth is a statistical measurement of the range of frequencies over which the channel can be considered "flat", or in other words the approximate maximum bandwidth or frequency interval over which two frequencies of a signal are likely to experience comparable or correlated amplitude fading. If the multip... |
https://en.wikipedia.org/wiki/Pole%20%28surveying%29 | In surveying, a pole is bar made of wood or metal and normally held vertical, upon which different instruments can be mounted: a prism, a GPS device, etc. It may be manufactured with a predetermined length (e.g., 2 meters) or may be graduated for different heights or stages.

https://en.wikipedia.org/wiki/Central%20tendon%20of%20diaphragm | The central tendon of the diaphragm is a thin but strong aponeurosis situated slightly anterior to the vault formed by the muscle, resulting in longer posterior muscle fibers.
It is inferior to the fibrous pericardium, which fuses with the central tendon of the diaphragm via the pericardiacophrenic ligament.

https://en.wikipedia.org/wiki/Square%20number | In mathematics, a square number or perfect square is an integer that is the square of an integer; in other words, it is the product of some integer with itself. For example, 9 is a square number, since it equals and can be written as .
The usual notation for the square of a number is not the product , but the equiva... |
https://en.wikipedia.org/wiki/Bathochromic%20shift | In spectroscopy, bathochromic shift (; hence less common alternate spelling "bathychromic") is a change of spectral band position in the absorption, reflectance, transmittance, or emission spectrum of a molecule to a longer wavelength (lower frequency). Because the red color in the visible spectrum has a longer wavele... |
https://en.wikipedia.org/wiki/Rotronics%20Wafadrive | The Rotronics Wafadrive is a magnetic tape storage peripheral launched in late 1984 for the ZX Spectrum home computer. Each tape is a continuous loop, unlike cassette tape. It was intended to compete with Sinclair's ZX Interface 1 and ZX Microdrive.
The Wafadrive comprises two continuous loop stringy floppy tape drive... |
