Metabolic P systems, shortly MP systems, are a special class of deterministic P systems, introduced for expressing biological metabolism. Their dynamics are computed by a special type of regulated multiset rewriting. In this chapter the basic results on MP systems are indicated and a procedure is outlined for constructing MP models of biological processes from time series of observed dynamics.

The following two-machine flow-shop scheduling problem is solved. Given jobs are classified into groups, and each machine needs some setup before the first job in a group is started processing. If a job in a group is started its process, all jobs in the group must be finished before a job in another group is processed. Each job may have a specified lag time between machines. Moreover, a series-...

We obtained the region of convergence and the summation formula for some modified generalized hypergeometric series (1.2). We also investigated rationality of the sums of the power series (1.3). As a result the series (1.4) cannot be the same rational number in all Zp. 1991 Mathematics Subject Classification: 40A30,40D99

A series of stable quadrupolar bis(p-aminophenyl)-carbo-benzenes, featuring both donor-donor-donor π-frustration and central macro-aromaticity, is described and compared to the acyclic dibutatrienylacetylene (DBA) reference series.

In order to understand the behaviour of distributed program environments, this paper describes a threedimensional visualization of communications. Most of previous visualizations presented communications by means of two dimensions of time and process, however, three dimensions are required to represent a message intermediary with visualization functions. We make use of a semantic configuration ...
