In addition, according to the valid closure property of regular languages (RL), a simple method to create a regular expression (RE) is proposed. The closure property of the permutation operator in Context-Free Languages (CFL) is proved and tested. In conclusion, by using our proposed methods...

url-filtering software relies on this property to build fast fa-based recognizers. implies that any finite language is a regular language. We can construct an re for any finite collection of words by listing them in a large alternation. Closure ensures that the alternation is an re and that...
Excitation is conducted in the reflex arcs in one direction, from the afferent neuron to the efferent one—never in the opposite direction. This property of reflex conduction is attributable to the chemical mechanism of interneuronal synaptic transmission, which consists basically in the formation and...
