https://en.wikipedia.org/wiki/Djenkolic%20acid | Djenkolic acid (or sometimes jengkolic acid) is a sulfur-containing non-protein amino acid naturally found in the djenkol beans of the Southeast Asian plant Archidendron jiringa. Its chemical structure is similar to cystine but contains a methylene (single carbon) unit in between the two sulfur atoms. There is about 20... |
https://en.wikipedia.org/wiki/Yamartino%20method | The Yamartino method is an algorithm for calculating an approximation of the circular variance of wind direction during a single pass through the incoming data.
Background
The simple method for calculating circular variance requires two passes through the list of values. The first pass determines the circular mean of ... |
https://en.wikipedia.org/wiki/Code%20page%201104 | Code page 1104 (CCSID 1104), also known as CP1104, F7DEC, ISO-IR-025 or NF Z 62-010 (1973) is an IBM code page number assigned to the French variant of DEC's National Replacement Character Set (NRCS). The 7-bit character set was introduced for DEC's computer terminal systems, starting with the VT200 series in 1983, but... |
https://en.wikipedia.org/wiki/Piezoelectric%20coefficient | The piezoelectric coefficient or piezoelectric modulus, usually written d33, quantifies the volume change when a piezoelectric material is subject to an electric field, or the polarization on the application of stress. In general, piezoelectricity is described by a tensor of coefficients ; see for further details.

https://en.wikipedia.org/wiki/Blitzar | In astronomy, blitzars are a hypothetical type of neutron star, specifically pulsars that can rapidly collapse into black holes if their spinning slows down. Heino Falcke and Luciano Rezzolla proposed these stars in 2013 as an explanation for fast radio bursts.
Overview
These stars, if they exist, are thought to start... |
