The threshold energy , to produce three particles of masses , , , i.e. 1 + 2 → a + b + c , {\displaystyle 1+2\to a+b+c,} is then found by assuming that these three particles are at rest in the center of mass frame (symbols with hat indicate quantities in the center of mass frame):
The threshold displacement energy is also often used in binary collision approximation computer codes such as SRIM [22] to estimate damage. However, the same caveats as for the Kinchin-Pease equation also apply for these codes (unless they are extended with a damage recombination model).
In electrophysiology, the threshold potential is the critical level to which a membrane potential must be depolarized to initiate an action potential.
This threshold is determined by minimizing intra-class intensity variance, or equivalently, by maximizing inter-class variance. [2] Otsu's method is a one-dimensional discrete analogue of Fisher's discriminant analysis , is related to Jenks optimization method , and is equivalent to a globally optimal k-means [ 3 ] performed on the intensity ...

In information theory, linguistics, and computer science, the Levenshtein distance is a string metric for measuring the difference between two sequences. The Levenshtein distance between two words is the minimum number of single-character edits (insertions, deletions or substitutions) required to change one word into the other.
