Rethinking Economics Using Complexity Theory

In this paper we argue that if we want to find a more satisfactory approach to tackling the major socio-economic problems we are facing, we need to thoroughly rethink the basic assumptions of macroeconomics and financial theory. Making minor modifications to the standard models to remove “imperfections” is not enough, the whole framework needs to be revisited.

African Bus Routes Redrawn Using Cell-Phone Data

Researchers at IBM, using movement data collected from millions of cell-phone users in Ivory Coast in West Africa, have developed a new model for optimizing an urban transportation system.

The IBM model prescribed changes in bus routes around the around Abidjan, the nation’s largest city. These changes—based on people’s movements as discerned from cell-phone records—could, in theory, slash travel times 10 percent.

ECCS'13: Satellite Meeting INFORMATION PROCESSING IN COMPLEX SYSTEMS (IPCS'13)

ECCS'13: Satellite Meeting
INFORMATION PROCESSING IN COMPLEX SYSTEMS (IPCS'13)

Wednesday September 18th, 2013
World Trade Center, Barcelona

All systems in nature have one thing in common: they process information. Information is registered in the state of a system and its elements, implicitly and invisibly. As elements interact, information is transferred. Indeed, bits of information about the state of one element will travel – imperfectly – to the state of the other element, forming its new state. This storage and transfer of information, possibly between levels of a multi level system, is imperfect due to randomness or noise. From this viewpoint, a system can be formalized as a collection of bits that is organized according to its rules of dynamics and its topology of interactions. Mapping out exactly how these bits of information percolate through the system could reveal new fundamental insights in how the parts orchestrate to produce the properties of the system. A theory of information processing would be capable of defining a set of universal properties of dynamical multi level complex systems, which describe and compare the dynamics of diverse complex systems ranging from social interaction to brain networks, from financial markets to biomedicine. Each possible combination of rules of dynamics and topology of interactions, with disparate semantics, would reduce to a single language of information processing.

Turning Oscillations Into Opportunities: Lessons from a Bacterial Decision Gate

Sporulation vs. competence provides a prototypic example of collective cell fate determination. The decision is performed by the action of three modules: 1) A stochastic competence switch whose transition probability is regulated by population density, population stress and cell stress. 2) A sporulation timer whose clock rate is regulated by cell stress and population stress. 3) A decision gate that is coupled to the timer via a special repressilator-like loop. We show that the distinct circuit architecture of this gate leads to special dynamics and noise management characteristics: The gate opens a time-window of opportunity for competence transitions during which it generates oscillations that are turned into a chain of transition opportunities – each oscillation opens a short interval with high transition probability. The special architecture of the gate also leads to filtering of external noise and robustness against internal noise and variations in the circuit parameters.

Mind-expanding: America’s neuroscience initiative

Mind-expanding: America’s neuroscience initiative | Complex Networks Everywhere | Scoop.it

AFTER much trailing, the reality is out. On April 2nd President Barack Obama announced that America’s government will back a project intended to unlock the mysteries of the human brain. It was, according to the trails, to have been known as the Brain Activity Map. But someone clearly spotted that BAM, as an acronym, is a hostage to fortune and the project is now to be known as the Brain Research through Advancing Innovative Neurotechnologies initiative. By what is no doubt a complete coincidence, that spells “BRAIN”.
