https://en.wikipedia.org/wiki/Shelah%20cardinal | In axiomatic set theory, Shelah cardinals are a kind of large cardinals. A cardinal is called Shelah iff for every , there exists a transitive class and an elementary embedding with critical point ; and .
A Shelah cardinal has a normal ultrafilter containing the set of weakly hyper-Woodin cardinals below it. |
https://en.wikipedia.org/wiki/Low-degree%20saturation | In a scale-free network the degree distribution follows a power law function. In some empirical examples this power-law fits the degree distribution well only in the high degree region, however for small degree nodes the empirical degree-distribution deviates from it. See for example the network of scientific citations... |
https://en.wikipedia.org/wiki/Symmetric%20logarithmic%20derivative | The symmetric logarithmic derivative is an important quantity in quantum metrology, and is related to the quantum Fisher information.
Definition
Let and be two operators, where is Hermitian and positive semi-definite. In most applications, and fulfill further properties, that also is Hermitian and is a density... |

https://en.wikipedia.org/wiki/Indexed%20language | Indexed languages are a class of formal languages discovered by Alfred Aho; they are described by indexed grammars and can be recognized by nested stack automata.
Indexed languages are a proper subset of context-sensitive languages. They qualify as an abstract family of languages (furthermore a full AFL) and hence sat... |
https://en.wikipedia.org/wiki/Cephaloticoccus%20capnophilus | Cephaloticoccus capnophilus is a Gram-negative and non-motile bacterium from the genus of Cephaloticoccus which has been isolated from the gut of the ant Cephalotes varians from the Crocodile Lake National Wildlife Refuge in Florida in the United States. |
https://en.wikipedia.org/wiki/Pulse%20width | The pulse width is a measure of the elapsed time between the leading and trailing edges of a single pulse of energy. The measure is typically used with electrical signals and is widely used in the fields of radar and power supplies. There are two closely related measures. The pulse repetition interval measures the time... |
https://en.wikipedia.org/wiki/Event-driven%20finite-state%20machine | In computation, a finite-state machine (FSM) is event driven if the transition from one state to another is triggered by an event or a message. This is in contrast to the parsing-theory origins of the term finite-state machine where the machine is described as consuming characters or tokens.
Often these machines are ... |
https://en.wikipedia.org/wiki/Image%20quality | Image quality can refer to the level of accuracy with which different imaging systems capture, process, store, compress, transmit and display the signals that form an image. Another definition refers to image quality as "the weighted combination of all of the visually significant attributes of an image". The difference... |
https://en.wikipedia.org/wiki/Meningeal%20branch%20of%20occipital%20artery | The meningeal branch of occipital artery ascends with the internal jugular vein, and enters the skull through the jugular foramen and condyloid canal, to supply the dura mater in the posterior fossa. |
https://en.wikipedia.org/wiki/Acridine%20orange | Acridine orange is an organic compound that serves as a nucleic acid-selective fluorescent dye with cationic properties useful for cell cycle determination. Acridine orange is cell-permeable, which allows the dye to interact with DNA by intercalation, or RNA via electrostatic attractions. When bound to DNA, acridine or... |
https://en.wikipedia.org/wiki/Jacobson%E2%80%93Bourbaki%20theorem | In algebra, the Jacobson–Bourbaki theorem is a theorem used to extend Galois theory to field extensions that need not be separable. It was introduced by for commutative fields and extended to non-commutative fields by , and who credited the result to unpublished work by Nicolas Bourbaki. The extension of Galois theo... |
