Computing an organism.
T ‘‘social amoebae’’ of species Dictyostelium discoideum roam individually through the soil as long as their bacterial food is present. The social phase for these cellular slime molds begins when the food supply is exhausted. After some hours, the assemblage of amoebae aggregate into several large groups, each of which forms a worm-like slug that propels itself toward heat and light. This bring...
متن کاملDigital On-Demand Computing Organism for Real-Time Systems
This paper presents the goals and the research approach of the project DodOrg (Digital On-demand Computing Organism for Real-Time Systems) within the Priority Programme “1183 Organic Computing”. The main goal of the project is the development of a biologically motivated computing organism with the three levels “brain”, “organ” and “cell”. On the brain level an organic robot control will be deve...
متن کاملComputing an organism: on the interface between informatic and dynamic processes.
The importance of interactions between processes at diverse space and time scales in biological information processing is a recurrent theme in the work of Michael Conrad (BioSystems, 1995: 35, 157-160; BioSystems, 1999: 52, 99-100). In this paper I present some results of explicit computational models that aim to capture and exploit some of the essential features of such multi-level processes. ...
متن کاملEvolution: What Is an Organism?
Defining an organism has long been a tricky problem for biologists. Recent work has shown how an approach based on adaptation can solve this problem, giving a conceptually simple two-dimensional measure of 'organismality'.
متن کاملWhat is an "Objectionable Organism"?
So, 21 CFR 211.113 limits the discussion to “products not required to be sterile” and 21 CFR211.84 states that the concern is “microbiological contamination that is objectionable in view of its intended use” leaving 21 CFR 211.165 to require lab testing relevant to “drug product required to be free of objectionable microorganisms”. This clearly defined concept of an “objectionable” organism the...
