  abstract	= "Splicing as a binary word/language operation is inspired
		  by the DNA recombination under the action of restriction
		  enzymes and ligases, and was first introduced by Tom Head
		  in 1987. Shortly thereafter, it was proven that the
		  languages generated by (finite) splicing systems form a
		  proper subclass of the class of regular languages. However,
		  the question of whether or not one can decide if a given
		  regular language is generated by a splicing system remained
		  open. In this paper we give a positive answer to this
		  question. Namely, we prove that, if a language is generated
		  by a splicing system, then it is also generated by a
		  splicing system whose size is a function of the size of the
		  syntactic monoid of the input language, and which can be
		  effectively constructed.",
