DNA Computing Based on Splicing: Universality Results
The paper extends some of the most recently obtained results on the computational universality of speci c variants of H systems (e.g. with regular sets of rules) and proves that we...

A computation-universal two-dimensional 8-state triangular reversible cellular automaton
A reversible cellular automaton (RCA) is a cellular automaton (CA) whose global function is injective and every configuration has at most one predecessor. Margolus showed that the...

About the Universality of the Billiard ball model
Block cellular automata (BCA) make local, parallel, synchronous and uniform updates of in nite lattices. In the one-dimensionalcase, there exist BCA with 11 states which are unive...

The Turing Closure of an Archimedean Field
A BSS machine is -uniform if it does not use exact tests; such machines are equivalent (modulo parameters) to Type 2 Turing machines. We define a notion of closure related to Turi...

A Direct Construction of a Universal Extended H System
Abstract. A direct universal extended H system receives as input the coding of an extended H system with double splicing and simulates it. It is the first time that a direct constr...
