Reducing the Size of Extended Gemmating P Systemshout (./.) communication rules generate any recursively enumerable language with three membranes, thus we present an optimal result on the necessary number of membranes to obtain computational completeness. In the case of gemmating P systems with only pre-dynamical rules, we prove that four membrane

P Systems Generating Trees a halting computation we do not take the terminal string generated in a designated output membrane, instead we consider the resulting tree representing the membrane structure of the final configuration as its result. We show that each recursively enumerable tree language can be obtained in that way

Asynchronous P Systems and P Systems Working in the Sequential Model mode (i.e., exactly one rule is applied in one derivation step). Moreover, we also recall some results for (tissue) P systems working in an asynchronous or sequential mode already in the original definition. Finally, we also raise several questions for future research in this subarea of (tissue) P

Rudolf Freund,Marion Oswald,Andrei Păunnamed TopHat, will be mounted on top of a balloon and will observe for two weeks in a circumpolar flight launched from McMurdo Station, Antarctica. By providing a combination of reduced systematics and extended integration time, it offers a factor of 30 improvement in sensitivity to CMBR anisotropy over existing measurements.
