  2. Adenosine monophosphate - Wikipedia

    en.wikipedia.org/wiki/Adenosine_monophosphate

    Adenosine monophosphate (AMP), also known as 5'-adenylic acid, is a nucleotide. AMP consists of a phosphate group, the sugar ribose , and the nucleobase adenine . It is an ester of phosphoric acid and the nucleoside adenosine . [ 1 ]

  3. Apache Spark - Wikipedia

    en.wikipedia.org/wiki/Apache_Spark

    Spark Core is the foundation of the overall project. It provides distributed task dispatching, scheduling, and basic I/O functionalities, exposed through an application programming interface (for Java, Python, Scala, .NET [16] and R) centered on the RDD abstraction (the Java API is available for other JVM languages, but is also usable for some other non-JVM languages that can connect to the ...

  4. Cyclic adenosine monophosphate - Wikipedia

    en.wikipedia.org/wiki/Cyclic_adenosine_monophosphate

    cAMP represented in three ways Adenosine triphosphate. Cyclic adenosine monophosphate (cAMP, cyclic AMP, or 3',5'-cyclic adenosine monophosphate) is a second messenger, or cellular signal occurring within cells, that is important in many biological processes. cAMP is a derivative of adenosine triphosphate (ATP) and used for intracellular signal transduction in many different organisms ...

  5. Selection (relational algebra) - Wikipedia

    en.wikipedia.org/wiki/Selection_(relational_algebra)

    In relational algebra, a selection (sometimes called a restriction in reference to E.F. Codd's 1970 paper [1] and not, contrary to a popular belief, to avoid confusion with SQL's use of SELECT, since Codd's article predates the existence of SQL) is a unary operation that denotes a subset of a relation.

    en.wikipedia.org/wiki/Karush–Kuhn–Tucker...

    The KKT conditions were originally named after Harold W. Kuhn and Albert W. Tucker, who first published the conditions in 1951. [2] Later scholars discovered that the necessary conditions for this problem had been stated by William Karush in his master's thesis in 1939. [3] [4]

  7. Differentiator - Wikipedia

    en.wikipedia.org/wiki/Differentiator

    The equation is true for any frequency signal, assuming an ideal op amp (though a real op-amp has limited bandwidth). The op amp's low-impedance output isolates the load of the succeeding stages, so this circuit has the same response independent of its load. If a constant DC voltage is applied as input, the output voltage is zero.

  8. Amplifier - Wikipedia

    en.wikipedia.org/wiki/Amplifier

    An amplifier, electronic amplifier or (informally) amp is an electronic device that can increase the magnitude of a signal (a time-varying voltage or current). It is a two-port electronic circuit that uses electric power from a power supply to increase the amplitude (magnitude of the voltage or current) of a signal applied to its input ...

  9. Extremophile - Wikipedia

    en.wikipedia.org/wiki/Extremophile

    The bright colors of Grand Prismatic Spring and Yellowstone National Park, are produced by thermophiles, a type of extremophile.. An extremophile (from Latin extremus 'extreme' and Ancient Greek φιλία (philía) 'love') is an organism that is able to live (or in some cases thrive) in extreme environments, i.e., environments with conditions approaching or stretching the limits of what known ...
