John S. Rieske and co-workers first discovered the protein and in 1964 isolated an acetylated form of the bovine mitochondrial protein. ... |
https://en.wikipedia.org/wiki/National%20CAD%20Standard | The National CAD Standard (NCS) is a collaborative effort in the United States among computer-aided design (CAD) and building information modeling (BIM) users. Its goal is to create a unified approach to the creation of building design data. Development of the NCS is open to all building professionals in a collaborativ... |
https://en.wikipedia.org/wiki/Grip%20strength | Grip strength is the force applied by the hand to pull on or suspend from objects and is a specific part of hand strength. Optimum-sized objects permit the hand to wrap around a cylindrical shape with a diameter from one to three inches. Stair rails are an example of where shape and diameter are critical for proper gri... |
https://en.wikipedia.org/wiki/Extended%20System%20Configuration%20Data | The Extended System Configuration Data (ESCD) is a specification for configuring x86 computers of the ISA PNP era. The specification was developed by Compaq, Intel and Phoenix Technologies. It consists of a method for storing configuration information in nonvolatile BIOS memory and three BIOS functions for working with... |
https://en.wikipedia.org/wiki/Code%20Access%20Security | Code Access Security (CAS), in the Microsoft .NET framework, is Microsoft's solution to prevent untrusted code from performing privileged actions. When the CLR loads an assembly it will obtain evidence for the assembly and use this to identify the code group that the assembly belongs to. A code group contains a permiss... |
https://en.wikipedia.org/wiki/Spidron | This article discusses the geometric figure; for the science-fiction character see Spidron (character).
In geometry, a spidron is a continuous flat geometric figure composed entirely of triangles, where, for every pair of joining triangles, each has a leg of the other as one of its legs, and neither has any point insi... |
https://en.wikipedia.org/wiki/YEPD | YEPD or yeast extract peptone dextrose, also often abbreviated as YPD, is a complete medium for yeast growth. It contains yeast extract, peptone, double-distilled water, and glucose (dextrose). It can be used as solid medium by including agar. The yeast extract will typically contain all the amino acids necessary for... |

https://en.wikipedia.org/wiki/Bitmap%20index | A bitmap index is a special kind of database index that uses bitmaps.
Bitmap indexes have traditionally been considered to work well for low-cardinality columns, which have a modest number of distinct values, either absolutely, or relative to the number of records that contain the data. The extreme case of low cardina... |
https://en.wikipedia.org/wiki/Least%20mean%20squares%20filter | Least mean squares (LMS) algorithms are a class of adaptive filter used to mimic a desired filter by finding the filter coefficients that relate to producing the least mean square of the error signal (difference between the desired and the actual signal). It is a stochastic gradient descent method in that the filter is... |
