https://en.wikipedia.org/wiki/Monosodium%20citrate | Monosodium citrate, more correctly, sodium dihydrogen citrate (Latin: ), is an acid salt of citric acid. Disodium citrate and trisodium citrate are also known. It can be prepared by partial neutralisation of citric acid with an aqueous solution of sodium bicarbonate or carbonate. It has a slightly acidic taste.

https://en.wikipedia.org/wiki/Christian%20views%20on%20cloning | Christians take multiple positions in the debate on the morality of human cloning. Since Dolly the sheep was successfully cloned on 5 July 1996, and the possibility of cloning humans became a reality, Christian leaders have been pressed to take an ethical stance on its morality. While many Christians tend to disagree w... |
https://en.wikipedia.org/wiki/Instability | In dynamical systems instability means that some of the outputs or internal states increase with time, without bounds. Not all systems that are not stable are unstable; systems can also be marginally stable or exhibit limit cycle behavior.
In structural engineering, a structural beam or column can become unstable whe... |
https://en.wikipedia.org/wiki/Scrapie | Scrapie () is a fatal, degenerative disease affecting the nervous systems of sheep and goats. It is one of several transmissible spongiform encephalopathies (TSEs), and as such it is thought to be caused by a prion. Scrapie has been known since at least 1732 and does not appear to be transmissible to humans. However, i... |
https://en.wikipedia.org/wiki/Rayleigh%20length | In optics and especially laser science, the Rayleigh length or Rayleigh range, , is the distance along the propagation direction of a beam from the waist to the place where the area of the cross section is doubled. A related parameter is the confocal parameter, b, which is twice the Rayleigh length. The Rayleigh leng... |
https://en.wikipedia.org/wiki/Certificate%20authority | In cryptography, a certificate authority or certification authority (CA) is an entity that stores, signs, and issues digital certificates. A digital certificate certifies the ownership of a public key by the named subject of the certificate. This allows others (relying parties) to rely upon signatures or on assertion... |
https://en.wikipedia.org/wiki/Super-recursive%20algorithm | In computability theory, super-recursive algorithms are a generalization of ordinary algorithms that are more powerful, that is, compute more than Turing machines. The term was introduced by Mark Burgin, whose book "Super-recursive algorithms" develops their theory and presents several mathematical models. Turing machi... |
https://en.wikipedia.org/wiki/Helium%20mass%20spectrometer | A helium mass spectrometer is an instrument commonly used to detect and locate small leaks. It was initially developed in the Manhattan Project during World War II to find extremely small leaks in the gas diffusion process of uranium enrichment plants. It typically uses a vacuum chamber in which a sealed container fill... |
https://en.wikipedia.org/wiki/Cray-2 | The Cray-2 is a supercomputer with four vector processors made by Cray Research starting in 1985. At 1.9 GFLOPS peak performance, it was the fastest machine in the world when it was released, replacing the Cray X-MP in that spot. It was, in turn, replaced in that spot by the Cray Y-MP in 1988.
The Cray-2 was the first... |
https://en.wikipedia.org/wiki/Boris%20Aronov | Boris Aronov (born March 13, 1963) is a computer scientist, currently a professor at the Tandon School of Engineering, New York University. His main area of research is computational geometry. He is a Sloan Research Fellow.
Aronov earned his B.A. in computer science and mathematics in 1984 from Queens College, City Un... |
https://en.wikipedia.org/wiki/Linear%20circuit | A linear circuit is an electronic circuit which obeys the superposition principle. This means that the output of the circuit F(x) when a linear combination of signals ax1(t) + bx2(t) is applied to it is equal to the linear combination of the outputs due to the signals x1(t) and x2(t) applied separately:
It is called... |
https://en.wikipedia.org/wiki/Fingerprint%20scanner | Fingerprint scanners are security systems of biometrics. They are used in police stations, security industries, smartphones, and other mobile devices.
Fingerprints
People have patterns of friction ridges on their fingers, these patterns are called the fingerprints. Fingerprints are uniquely detailed, durable over an i... |
