Technological processes, reconstructed from the archaeological record, are used to study
the evolution of behaviour and cognition of Neanderthals and early modern humans. In …

The designer of a software system, like the architect of a building, needs to be aware of the
construction techniques available and to choose the ones that are the most appropriate. This …

We implement a method from computer sciences to address a challenge in Paleolithic
archaeology: how to infer cognition differences from material culture. Archaeological …

Motivation Transcriptional regulation mechanisms allow cells to adapt and respond to
external stimuli by altering gene expression. The possible cell transcriptional states are …

The aim of this paper is to present an introduction to the theory of Petri nets. The subject
matter of this theory is distributed systems and processes. In our presentation, we shall …

In the human pathogen Streptococcus pneumoniae, the gene regulatory circuit leading to
the transient state of competence for natural transformation is based on production of an …

Abstract Background The concept of Petri nets (PN) is widely used in systems biology and
allows modeling of complex biochemical systems like metabolic systems, signal …

Background Quorum sensing drives biofilm formation in bacteria in order to ensure that
biofilm formation only occurs when colonies are of a sufficient size and density. This spatial …

In order to compare different distributed software implementations of the token game we start
out from an explicitly defined basis, called the process paradigm. Quality criteria for …

In M-timed Petri nets, firing times are exponentially distributed random variables associated
with transitions of a net. Several classes of M-timed Petri nets are discussed in this paper to …
