https://en.wikipedia.org/wiki/Generalized%20complex%20structure | In the field of mathematics known as differential geometry, a generalized complex structure is a property of a differential manifold that includes as special cases a complex structure and a symplectic structure. Generalized complex structures were introduced by Nigel Hitchin in 2002 and further developed by his student... |
https://en.wikipedia.org/wiki/Beauty%20micrometer | The beauty micrometer, also known as the beauty calibrator, was a device designed in the early 1930s to help in the identification of the areas of a person's face which need to have their appearance reduced or enhanced by make-up. The inventors include famed beautician Max Factor Sr. A 2013 Wired article described the ... |
https://en.wikipedia.org/wiki/Peptide%20hormone | Peptide hormones are hormones whose molecules are peptides. Peptide hormones have shorter amino acid chain lengths than protein hormones. These hormones have an effect on the endocrine system of animals, including humans. Most hormones can be classified as either amino acid–based hormones (amine, peptide, or protein) o... |

https://en.wikipedia.org/wiki/Browser%20security | Browser security is the application of Internet security to web browsers in order to protect networked data and computer systems from breaches of privacy or malware. Security exploits of browsers often use JavaScript, sometimes with cross-site scripting (XSS) with a secondary payload using Adobe Flash. Security exploit... |
https://en.wikipedia.org/wiki/Hankel%20singular%20value | In control theory, Hankel singular values, named after Hermann Hankel, provide a measure of energy for each state in a system. They are the basis for balanced model reduction, in which high energy states are retained while low energy states are discarded. The reduced model retains the important features of the original... |
https://en.wikipedia.org/wiki/Traumatic%20insemination | Traumatic insemination, also known as hypodermic insemination, is the mating practice in some species of invertebrates in which the male pierces the female's abdomen with his aedeagus and injects his sperm through the wound into her abdominal cavity (hemocoel). The sperm diffuses through the female's hemolymph, reachin... |
