https://en.wikipedia.org/wiki/Corresponding%20sides%20and%20corresponding%20angles | In geometry, the tests for congruence and similarity involve comparing corresponding sides and corresponding angles of polygons. In these tests, each side and each angle in one polygon is paired with a side or angle in the second polygon, taking care to preserve the order of adjacency.
For example, if one polygon has ... |
https://en.wikipedia.org/wiki/4-Anisaldehyde | 4-Anisaldehyde, or p-Anisaldehyde, is an organic compound with the formula CH3OC6H4CHO. The molecule consists of a benzene ring with a formyl and a methoxy group. It is a colorless liquid with a strong aroma. It provides sweet, floral and strong aniseed odor. Two isomers of 4-anisaldehyde are known, ortho-anisaldehy... |

In 1968, he founded Wild Sanctuary, an organization dedicated to the recording and archiving of natural soundscapes. Krause is an author, a bio-acoustician, a speaker, and natural sound artist who coined the terms geophony, biop... |
https://en.wikipedia.org/wiki/Cinderella%20effect | In evolutionary psychology, the Cinderella effect is the phenomenon of higher incidence of different forms of child abuse and mistreatment by stepparents than by biological parents. It takes its name from the fairy tale character Cinderella, which is about a girl who is mistreated by her stepsisters and stepmother. Evo... |
https://en.wikipedia.org/wiki/Memory-bound%20function | Memory bound refers to a situation in which the time to complete a given computational problem is decided primarily by the amount of free memory required to hold the working data. This is in contrast to algorithms that are compute-bound, where the number of elementary computation steps is the deciding factor.
Memory a... |
https://en.wikipedia.org/wiki/Metabolic%20network%20modelling | Metabolic network modelling, also known as metabolic network reconstruction or metabolic pathway analysis, allows for an in-depth insight into the molecular mechanisms of a particular organism. In particular, these models correlate the genome with molecular physiology. A reconstruction breaks down metabolic pathways (s... |
https://en.wikipedia.org/wiki/Microscopic%20reversibility | The principle of microscopic reversibility in physics and chemistry is twofold:
First, it states that the microscopic detailed dynamics of particles and fields is time-reversible because the microscopic equations of motion are symmetric with respect to inversion in time (T-symmetry);
Second, it relates to the statist... |
https://en.wikipedia.org/wiki/Deep%20fibular%20nerve | The deep fibular nerve (also known as deep peroneal nerve) begins at the bifurcation of the common fibular nerve between the fibula and upper part of the fibularis longus, passes infero-medially, deep to the extensor digitorum longus, to the anterior surface of the interosseous membrane, and comes into relation with th... |
https://en.wikipedia.org/wiki/YIG%20sphere | Yttrium iron garnet spheres (YIG spheres) serve as magnetically tunable filters and resonators for microwave frequencies. YIG filters are used for their high Q factors, typically between 100 and 200. A sphere made from a single crystal of synthetic yttrium iron garnet acts as a resonator.

https://en.wikipedia.org/wiki/Fountain%20code | In coding theory, fountain codes (also known as rateless erasure codes) are a class of erasure codes with the property that a potentially limitless sequence of encoding symbols can be generated from a given set of source symbols such that the original source symbols can ideally be recovered from any subset of the encod... |
https://en.wikipedia.org/wiki/Sharps%20waste | Sharps waste is a form of biomedical waste composed of used "sharps", which includes any device or object used to puncture or lacerate the skin. Sharps waste is classified as biohazardous waste and must be carefully handled. Common medical materials treated as sharps waste are
hypodermic needles,
