Complexity classes for membrane systems
Abstract. We compare various computational complexity classes defined within the framework of membrane systems, a distributed parallel computing device which is inspired from the f...

The computational power of membrane systems under tight uniformity conditions
We apply techniques from complexity theory to a model of biological cellular membranes known as membrane systems or P-systems. Like Boolean circuits, membrane systems are defined ...

Non-confluence in divisionless P systems with active membranes
We describe a solution to the SAT problem via non-confluent P systems with active membranes, without using membrane division rules. Furthermore, we provide an algorithm for simula...

Membrane Remodeling and Diffusion of Cytochrome C from a Geometrically Idealized Mitochondrial Crista
In healthy eukaryotic cells, mitochondria have an outer membrane that surrounds a complex inner membrane structure [7,8]. Cytochrome c is found in the space between the two membra...
