The approach of this work numerically defines complexity. Such a definition allows unambiguously comparing the complexity of various societies.The paper brings an incremental contribution to archaeological and historical debates, by using classical stability theory for modeling complex socio-political systems....

Overview of systems models Here, we briefly describe the four previously published models used to investigate the effects of multiple drivers and noise upon the timing of ATDCs. Each model was replicated and simulated within the system dynamics software STELLA Architect v.1.6.1 (ref.39), with ...
structure of complex systems often evolves over time (co-evolution), and cycles may get created and destroyed in this process. This structural evolution is generally the result of an adaptation process32, and happens at a much slower rate than the dynamics of the nodes. For example, evolutionar...
Network growth is ubiquitous in nature (e.g., biological networks) and technological systems (e.g., modern infrastructures). To understand how certain dynamical behaviors can or cannot persist as the underlying network grows is a problem of increasing importance in complex dynamical systems as well...
Systems Collapse as Social Transformation: Catastrophe and Anastrophe in Early State Societies 来自 Elsevier 喜欢 0 阅读量: 25 作者: AC Renfrew 摘要: This chapter discusses several features of a system collapse and the aftermath of such a collapse. It has been observed that there are cases where...
The collapse of major histocompatiblity complex (MHC) class-I-dependent immune privilege can lead to autoimmune disease or fetal rejection. Pragmatic and instructive models are needed to clarify the as yet obscure controls of MHC class I down-regulation in situ, to dissect the principles of ...
Rather, "mood and anxiety disorders involve immensely complex interconnected systems or networks of organization within the brain." The authors are quick to point out that the causes of depression are complex and only partly understood. Nevertheless, a picture is beginning to emerge of ...
The importance of a component in a structure system can be represented by a quantitative coefficient [14], whose value embodies the risk of losing the component to the entire structure. The negative effect of the missing component is simulated by the so-called conceptual removal method. A compon...
Colony collapse disorder (CCD), disorder affecting honeybee colonies that is characterized by sudden colony death, with a lack of healthy adult bees inside the hive. Although the cause is not known, researchers suspect that multiple factors may be involv
