Kelly in the study of quasimetrics, i.e. distance functions that are not required to be symmetric.

https://en.wikipedia.org/wiki/Valuative%20criterion | In mathematics, specifically algebraic geometry, the valuative criteria are a collection of results that make it possible to decide whether a morphism of algebraic varieties, or more generally schemes, is universally closed, separated, or proper.
Statement of the valuative criteria
Recall that a valuation ring A is a... |
https://en.wikipedia.org/wiki/Picornavirales | Picornavirales is an order of viruses with vertebrate, invertebrate, protist and plant hosts. The name has a dual etymology. First, picorna- is an acronym for poliovirus, insensitivity to ether, coxsackievirus, orphan virus, rhinovirus, and ribonucleic acid. Secondly, pico-, meaning extremely small, combines with RN... |
https://en.wikipedia.org/wiki/StarLink%20corn%20recall | The StarLink corn recalls occurred in the autumn of 2000, when over 300 food products were found to contain a genetically modified corn that had not been approved for human consumption. It was the first-ever recall of a genetically modified food. The anti-GMO activist coalition Genetically Engineered Food Alert, which ... |
https://en.wikipedia.org/wiki/Turing%20pattern | The Turing pattern is a concept introduced by English mathematician Alan Turing in a 1952 paper titled "The Chemical Basis of Morphogenesis" which describes how patterns in nature, such as stripes and spots, can arise naturally and autonomously from a homogeneous, uniform state. The pattern arises due to Turing instabi... |

https://en.wikipedia.org/wiki/Arterial%20arcades | The arterial arcades (intermesenteric arterial anastomoses or Riolan arcades) are a series of anastomosing arterial arches between the arterial branches of the jejunum and ileum.
Nearest the duodenum the mesenteric loops are primary, the vasa recta are long and regular in distribution, and the translucent spaces (lune... |
https://en.wikipedia.org/wiki/Pyocyanase | Pyocyanase was the first antibiotic drug to be used in hospitals. It is no longer used today.
Rudolph Emmerich and Oscar Löw, two German physicians who were the first to make an effective medication from microbes, conducted experiments in the 1890s, roughly 30 years after Louis Pasteur showed that many diseases were ca... |
https://en.wikipedia.org/wiki/Server-sent%20events | Server-Sent Events (SSE) is a server push technology enabling a client to receive automatic updates from a server via an HTTP connection, and describes how servers can initiate data transmission towards clients once an initial client connection has been established. They are commonly used to send message updates or con... |
https://en.wikipedia.org/wiki/Newton%27s%20identities | In mathematics, Newton's identities, also known as the Girard–Newton formulae, give relations between two types of symmetric polynomials, namely between power sums and elementary symmetric polynomials. Evaluated at the roots of a monic polynomial P in one variable, they allow expressing the sums of the k-th powers of a... |
https://en.wikipedia.org/wiki/Depletion%20force | A depletion force is an effective attractive force that arises between large colloidal particles that are suspended in a dilute solution of depletants, which are smaller solutes that are preferentially excluded from the vicinity of the large particles. One of the earliest reports of depletion forces that lead to partic... |
https://en.wikipedia.org/wiki/Oblique%20projection | Oblique projection is a simple type of technical drawing of graphical projection used for producing two-dimensional (2D) images of three-dimensional (3D) objects.
The objects are not in perspective and so do not correspond to any view of an object that can be obtained in practice, but the technique yields somewhat con... |
https://en.wikipedia.org/wiki/Primordium | A primordium (; : primordia; synonym: anlage) in embryology, is an organ or tissue in its earliest recognizable stage of development. Cells of the primordium are called primordial cells. A primordium is the simplest set of cells capable of triggering growth of the would-be organ and the initial foundation from which a... |
