DYNAMIC BEHAVIOR OF A NONLINEAR SINGLE SPECIES DIFFUSIVE SYSTEM
CHEN, FENGDE; CHEN, XIAOXING; SHI, JINLIN - In: Advances in Complex Systems (ACS) 08 (2005) 04, pp. 399-417
In this paper, we consider the following nonlinear single species diffusive system \begin{eqnarray*} \dot{x}_i(t)&=& x_i(t)\left(b_i(t)-\sum_{k=1}^{l_i}a_{ik}(t)(x_i(t))^{\beta_{ik}}\right)\\ && +\,\sum_{j=1}^{n}D_{ij}(t)(x_j(t)-x_i(t)),\quad (i,j=1,2,\ldots,n), \end{eqnarray*} where bi(t),...

DO LANGUAGE CHANGE RATES DEPEND ON POPULATION SIZE?
WICHMANN, SØREN; STAUFFER, DIETRICH; SCHULZE, CHRISTIAN; … - In: Advances in Complex Systems (ACS) 11 (2008) 03, pp. 357-369
An earlier study [24] concluded, based on computer simulations and some inferences from empirical data, that languages will change the more slowly the larger the population gets. We replicate this study using a more complete language model for simulations (the Schulze model combined with a...

BETTER BEING THIRD THAN SECOND IN A SEARCH FOR A MAJORITY OPINION
STAUFFER, DIETRICH - In: Advances in Complex Systems (ACS) 05 (2002) 01, pp. 97-100
Monte Carlo simulations of a Sznajd model show that if a near-consensus is formed out of four initially equally widespread opinions, the one which at intermediate times is second in the number of adherents usually loses out against the third-placed opinion.

THE SPATIAL AND TEMPORAL DIFFUSION OF STYLISTIC INNOVATIONS IN MATERIAL CULTURE
SCHOLNICK, JONATHAN B. - In: Advances in Complex Systems (ACS) 15 (2012) 01, pp. 1150010-1
Many explanations for the sigmoid or S-shaped curves that characterize the diffusion of innovations through time have … underlying social forces that structure diffusion through both space and time. Using historic New England gravestones and their … among consumers can generate both wave-like diffusion patterns through space and lead to the persistence of cultural …

MODULARITY, DEPENDENCE AND CHANGE
GEIPEL, MARKUS MICHAEL - In: Advances in Complex Systems (ACS) 15 (2012) 06, pp. 1250083-1
Technological artifacts such as software often comprise a large number of modules; more than twenty thousand in the case of the Java software Eclipse. While on the micro-level this system is modular, how should the building blocks be arranged on the macro-level? In the literature this question...

THE ROLE OF HAPLOTYPE COMPLEMENTATION AND PURIFYING SELECTION IN THE GENOME EVOLUTION
CEBRAT, STANISŁAW; WAGA, WOJCIECH; STAUFFER, DIETRICH - In: Advances in Complex Systems (ACS) 15 (2012) su, pp. 1250041-1
We discuss two different ways of evolution for chromosomes and genomes. Purifying selection dominates in large …
