A Coarse-Grained Model of Evolution (2007)
With Variable System, C. Wilke, T. Martinetz
ecies in the ecosystem is significantly reduced, and the process of regrowth of new species can take a long time. We here propose a generalization to the coherent noise model used by Newman, where...

Grundlingh, M.L., Von St Ange, U.B., Bolton, J.J., Bursey, M., Compagno, L., Cooper, R., ...
AfrOBIS is one of 11 global nodes of the Ocean Biogeographic Information System (OBIS), a freely accessible network of databases collating marine data in support of the Census of Marine...
Golubovski, Yu. B., Kozakov, R. V., Wilke, C., Nekutchaev, V. O.
Time resolved measurements of the electron energy distribution function (EEDF) and plasma potential in longitudinal and radial directions under the presence of S- and P- striations in neon were...
Golubovskii, Yu. B., Kozakov, R. V., Wilke, C., Behnke, J., Nekutchaev, V.
Calculations of the electron energy distribution function (EEDF) in the striation-like sine modulated electric field are performed. Dependence on a spatial period length was investigated....

Wirkungsabschätzung und Bilanzbewertung (2001)
Die Hasseröder Brauerei GmbH ist ein Ein-Produkt-Betrieb und stellt ausschließlich Bier der Marke "Hasseröder Premium Pils" her. Sie hat die Zielsetzung, eigenverantwortlich zu einer Verringerung...
How fast do structures emerge in hypercycle-systems? (1998)
Altmeyer, S., Wilke, C., Martinetz, T.
A general framework for the simulation of reaction-diffusion systems with probabilistic cellular automata is presented. The basic reaction probabilities of the chemical model translate directly into...
Large-scale evolution and extinction in a hierarchically structured environment (1998)
Wilke, C., Altmeyer, S., Martinetz, T.
A class of models for large-scale evolution and mass extinctions is presented. These models incorporate environmental changes on all scales, from influences on a single species to global effects....
Mesoscopic Analysis of an Artificial Chemistry with Self-organizing Topology (1998)
C. Wilke, S. Altmeyer, T. Martinetz, Peter Dittrich, Jens Ziegler, Wolfgang Banzhaf
The analysis of artificial life systems is often much harder than their construction, especially in population-based systems with a huge number of interacting individuals. Due to insufficient results...
C. Wilke, S. Altmeyer, T. Martinetz, Peter Dittrich, Jens Ziegler
Introduction to Artificial Chemistries An artificial chemistry is an artificial system, which is similar to a chemical system. Bagley and Farmer write in [1]: An artificial chemistry is a set of...
Abstract Aftershocks in Coherent-Noise Models (1998)
C. Wilke, S. Altmeyer, T. Martinetz
The decay pattern of aftershocks in the so-called ’coherent-noise ’ models [M. E. J. Newman and K. Sneppen, Phys. Rev. E54, 6226 (1996)] is studied in detail. Analytical and numerical results...
Aftershocks in Coherent-Noise Models (1997)
Wilke, C., Altmeyer, S., Martinetz, T.
The decay pattern of aftershocks in the so-called 'coherent-noise' models [M. E. J. Newman and K. Sneppen, Phys. Rev. E54, 6226 (1996)] is studied in detail. Analytical and numerical results show...
A Simple Model of Evolution with Variable System Size (1997)
A simple model of biological extinction with variable system size is presented that exhibits a power-law distribution of extinction event sizes. The model is a generalization of a model recently...
Axion cyclotron emissivity of magnetized white dwarfs and neutron stars (1997)
Kachelriess, M., Wilke, C., Wunner, G.
The energy loss rate of a magnetized electron gas emitting axions a due to the process $e^- \to e^- +a$ is derived for arbitrary magnetic field strength B. Requiring that for a strongly magnetized...
We present the results of a numerical calculation of the photon splitting rate below the electron-pair creation threshold ($\omega \le 2m$) in magnetic fields $B ~{> \atop \sim}~ B_{\rm cr} = m^2 /e...
