A. Lindenmayerial cells are unique in that they are interconnected to each other via gap junctions and thus act as an electrical syncytium, a vast number of important cellular receptors and signal transduction pathways allow individual cells to receive and respond to various signals. These receptors and signal tr

Paul M. B. Vitányicies or races is not defensible from a biological perspective. Evidence points to a relatively recent origin of the human species and to a substantial level of genetic exchanges between migrating human populations. The persistent health disparities between populations of varying ethnic origins that

Free groups in Lindenmayer systems,there exists a locally catenative equation in the free group which defines the DOL sequence. An algorithm is given which finds the generators of the free group if it is finitely generated..A conjecture is stated in terms of the existence of a certain group. The conjecture implies the solvability of the DOL equivalence problem.

Context in parallel rewriting,ems are introduced in this paper. We investigate the generative power of these new types of context sensitive parallel rewriting systems and we compare it to the generative power of TOL-systems , L-systems with interaction , regular grammars and context sensitive grammars.
