Complexity Digest wrote a new blog post titled Cascading Failures as Continuous Phase-Space Transitions

In network systems, a local perturbation can amplify as it propagates, potentially leading to a large-scale cascading failure. Here we derive a continuous model to advance our understanding of cascading failures in power-grid networks. The model accounts for both the failure of transmission lines and the desynchronization of power generators and incorporates the transient dynamics between successive steps of the cascade. In this framework, we show that a cascade event is a phase-space transition from an equilibrium state with high energy to an equilibrium state with lower energy, which can be...

Complexity Digest wrote a new blog post titled Unveiling The Structure Of Information: The Fundamental Scale

Information has been a matter of intense study and discussion for the last century. The very nature of information, not a physical object, not an entirely abstract entity, has fostered this endless discussion which had some of its first episodes back in the 40’s with the arguments between Wiener and Shannon. Whether information is the effect produced by the received pattern of signals or the pattern of signals itself, the truth is that these patterns exist and we are devoted to deep into them to find a model for their structures and to establish useful comparisons among them.

Complexity Digest wrote a new blog post titled A (partially) interactive introduction to Systems Sciences

Complexity Digest has been successfully networking the complexity community since fall of 1999. It is edited by Dr. Carlos Gershenson, and published by the Instituto de Investigaciones en Matematicas Aplicadas y en Sistemas (IIMAS) and the Centro de Ciencias de la Complejidad (C3) of the Universidad Nacional Autonoma de Mexico (UNAM), the most prestigious university in Latin America and hispanic countries.

Its founding editor was Dr Gottfried Mayer, a member of the complexity community since his residence at the Santa Fe Institute in its early days. He deceased victim of cancer on January, 2009. Until then, the sponsor of ComDig was Dean LeBaron, trustee of SFI and investment commentator. ComDig was created by Gottfried and Dean, and we try to follow their original ideas.

Contributors are welcome to send submissions to editoracomdig.unam.mx.

ComDig hopes to be of use to all of the growing number of complexity organizations and supported by them.

ComDig has been distributed by weekly email to a list of people who request copies free of charge. ComDig iss also available through RSS (Real Simple Syndication).

Copies will be made available to organizations who may wish to repost ComDig to their own mailing lists. Some may customize the appearance of the content provided to them.

Readership should range from academics in almost every field to business people who want to know how to use the concepts. From students in search of knowledge to journalists looking for items from this rich field of activity. All are encouraged so long as it is of use to them.
