UNIVERSITY OF HERTFORDSHIRE COMPUTER SCIENCE RESEARCH COLLOQUIUM presents "Mathematical Modelling of Persistent Splicing Systems in DNA Computing" Dr. Fariba Karimi (Royal Society Wolfson Biocomputation Laboratory, Centre for Computer Science and Informatics Research, University of Hertfordshire) 30 October 2013 (Wednesday) 1 pm -2 pm Hatfield, College Lane Campus Seminar Room C152 Everyone is Welcome to Attend Refreshments will be available Abstract: Splicing system is a bio-inspired computational model that interprets the Cutting and pasting behavior of DNA molecules in the presence of restriction enzymes. Splicing system is defined under the framework of formal language theory. Different types of splicing systems and languages such as uniform, null-context, simple, permanent, persistent and strictly locally testable are introduced by researchers. In this talk some properties of persistent and permanent splicing systems are discussed. The interesting point about these two systems is that if restriction enzymes are chosen from actual biological sense, then the resulting systems are often persistent and permanent. The main feature of them is that the property of being crossing of a site is preserved and consequently, the enzymes cleavage process persists. Some sufficient conditions are provided for splicing systems to be persistent and permanent. Also, the concepts of self-closed, crossing-preserved and extended crossing-preserved are introduced that are closely connected to the notions of persistent and permanent systems. Furthermore, a laboratory experiment has been conducted to biologically validate the behavior of persistent splicing systems. --------------------------------------------------- Hertfordshire Computer Science Research Colloquium http://cs-colloq.stca.herts.ac.uk
