https://en.wikipedia.org/wiki/Methylenetetrahydrofolate%20reductase | Methylenetetrahydrofolatereductase (MTHFR) is the rate-limiting enzyme in the methyl cycle, and it is encoded by the MTHFR gene. Methylenetetrahydrofolate reductase catalyzes the conversion of 5,10-methylenetetrahydrofolate to 5-methyltetrahydrofolate, a cosubstrate for homocysteine remethylation to methionine. Natural... |
https://en.wikipedia.org/wiki/Lupus%20anticoagulant | Lupus anticoagulant is an immunoglobulin that binds to phospholipids and proteins associated with the cell membrane. Its name is a partial misnomer, as it is actually a prothrombotic antibody in vivo. Lupus anticoagulant in living systems causes a decrease in clotting time. The name derives from their properties in vit... |
https://en.wikipedia.org/wiki/Rate%20of%20flow | Rate of flow may refer to:
Mass flow rate, the movement of mass per time
Volumetric flow rate, the volume of a fluid which passes through a given surface per unit of time
Heat flow rate, the movement of heat per time

https://en.wikipedia.org/wiki/Continued%20fraction%20factorization | In number theory, the continued fraction factorization method (CFRAC) is an integer factorization algorithm. It is a general-purpose algorithm, meaning that it is suitable for factoring any integer n, not depending on special form or properties. It was described by D. H. Lehmer and R. E. Powers in 1931, and developed a... |
https://en.wikipedia.org/wiki/Lambda%20point | The lambda point is the temperature at which normal fluid helium (helium I) makes the transition to superfluid helium II (approximately 2.17 K at 1 atmosphere). The lowest pressure at which He-I and He-II can coexist is the vapor−He-I−He-II triple point at and , which is the "saturated vapor pressure" at that tempera... |
https://en.wikipedia.org/wiki/Butterfly%20theorem | The butterfly theorem is a classical result in Euclidean geometry, which can be stated as follows:
Let be the midpoint of a chord of a circle, through which two other chords and are drawn; and intersect chord at and correspondingly. Then is the midpoint of .
Proof
A formal proof of the theorem is as follow... |
https://en.wikipedia.org/wiki/Fairchild%20F8 | The Fairchild F8 is an 8-bit microprocessor system from Fairchild Semiconductor, announced in 1974 and shipped in 1975. The original processor family included four main 40-pin integrated circuits (ICs); the 3850 CPU which was the arithmetic logic unit, the 3851 Program Storage Unit (PSU) which contained of program ROM... |
https://en.wikipedia.org/wiki/Mostek | Mostek Corporation was a semiconductor integrated circuit manufacturer, founded in 1969 by L. J. Sevin, Louay E. Sharif, Richard L. Petritz and other ex-employees of Texas Instruments. At its peak in the late 1970s, Mostek held an 85% market share of the dynamic random-access memory (DRAM) memory chip market worldwide,... |
https://en.wikipedia.org/wiki/Erythroplakia | Erythroplakia is a clinical term to describe any erythematous (red) area on a mucous membrane, that cannot be attributed to any other pathology.
The term erythroplasia was coined by Louis Queyrat to describe a precancerous red lesion of the penis. This gave rise to the term erythoplasia of Queyrat. Depending upon the ... |
https://en.wikipedia.org/wiki/National%20Semiconductor%20SC/MP | National Semiconductor's SC/MP (pronounced scamp) for Simple Cost-effective Micro Processor, is an early 8-bit microprocessor which became available in April 1976. It was designed to allow systems to be implemented with the minimum number of additional support chips. SC/MP included a daisy-chained control pin that allo... |
https://en.wikipedia.org/wiki/Failure%20rate | Failure rate is the frequency with which an engineered system or component fails, expressed in failures per unit of time. It is usually denoted by the Greek letter λ (lambda) and is often used in reliability engineering.
The failure rate of a system usually depends on time, with the rate varying over the life cycle o... |
