Complexity Digest wrote a new blog post titled Guest Editorial: Special Issue on Approaches to Control Biological and Biologically Inspired Networks
The emerging field at the intersection of quantitative biology, network modeling, and control theory has enjoyed significant progress in recent years. This Special Issue brings together a selection of papers on complementary approaches to observe, identify, and control biological and biologically inspired networks. These approaches advance the state of the art in the field by addressing challenges common to many such networks, including high dimensionality, strong nonlinearity, uncertainty, and limited opportunities for observation and intervention. Because these challenges are not unique to...

Complexity Digest wrote a new blog post titled The biology of consciousness from the bottom up
This essay aims to outline a scientific approach to the investigation of consciousness emphasizing achievements and promise of hardcore bottom-up biology. We propose to contemplate what would be the minimal requirements of consciousness in the simplest of life forms. We show that, starting from the molecular nuts and bolts of such life forms, it is the extreme multitudinousness of the moving material components forming consciousness, and their organized swarming, that appears outstanding. This is in stark contrast with the impression obtained from introspection that consciousness is a single,...

Complexity Digest wrote a new blog post titled Guidelines for quantitative and qualitative studies of sensory substitution experience
Information that is normally accessed through a sensory modality (substituted modality, e.g., vision) is provided by sensory substitution devices (SSDs) through an alternative modality such as hearing or touch (i.e., substituting modality). SSDs usually support disabled users by replacing sensory inputs that have been lost, but they also offer a unique opportunity to study adaptation and flexibility in human perception. Current debates in sensory substitution (SS) literature focus mostly on its neural correlates and behavioural consequences. In particular, studies have demonstrated the neural...

Complexity Digest wrote a new blog post titled The Relevance of Informational Infrastructures in Future Cities
Cities around the world are installing digital architectures of sensors, computational cores and telecommunications in the urban fabric, transforming existing infrastructure systems into multi-functional informational and services platforms in the process. The fast pace of digitization is often hard for cities to fathom, many of which are challenged by a silent privatization of the informational value of public spaces and the under-development of the potential of 21st century digital infrastructures due to a mono functional non-inclusive process of design. This is compounded by the power...

Complexity Digest wrote a new blog post titled Five Principles for Organizing Collective Intelligence
Big Mind is notable for a number of reasons. One of them is that we don’t have a lot of guides for managing and optimizing collective intelligence, in contrast to the shelves and shelves of books describing how to optimize the output of individual brains. Another reason is the five fundamental principles that Mulgan offers, in the excerpt below, in a nuanced answer to the question: “What is it, at the micro and macro levels, that allows collective intelligence to flower?” Source: sloanreview.mit.edu Featured excerpt from Big Mind: How Collective Intelligence Can Change Our World.

Complexity Digest wrote a new blog post titled Topography of epithelial–mesenchymal plasticity
Cells can change their phenotype from epithelial to mesenchymal during development and in cancer progression, where this transition is often associated with metastasis and poor disease prognosis. Here we show this process involves the transit through a multitude of metastable hybrid phenotypes in a way that is similar to the driven dynamics of disordered materials. Our method shows that highly aggressive hybrid epithelial/mesenchymal cell phenotypes are located in metastable regions that can easily switch under external and internal perturbations. We propose a general mapping strategy that...

Complexity Digest wrote a new blog post titled Network Effects, Origin Stories, and the Evolution of Tech
“The rules of the game are different in tech,” argues — and has long argued, despite his views not being accepted at first — W. Brian Arthur, technologist-turned-economist who first truly described the phenomenon of “positive feedbacks” in the economy or “increasing returns” (vs. diminishing returns) in the new world of business… a.k.a. network effects. A longtime observer of Silicon Valley and the tech industry, he’s seen how a few early entrepreneurs first got it, fewer investors embrace it, entire companies be built around it, and still yet others miss it… even today.

Complexity Digest wrote a new blog post titled Addressing the minimum fleet problem in on-demand urban mobility
Information and communication technologies have opened the way to new solutions for urban mobility that provide better ways to match individuals with on-demand vehicles. However, a fundamental unsolved problem is how best to size and operate a fleet of vehicles, given a certain demand for personal mobility. Previous studies1,2,3,4,5 either do not provide a scalable solution or require changes in human attitudes towards mobility. Here we provide a network-based solution to the following ‘minimum fleet problem’, given a collection of trips (specified by origin, destination and start...

Complexity Digest wrote a new blog post titled Predicting the temporal activity patterns of new venues
Estimating revenue and business demand of a newly opened venue is paramount as these early stages often involve critical decisions such as first rounds of staffing and resource allocation. Traditionally, this estimation has been performed through coarse-grained measures such as observing numbers in local venues or venues at similar places (e.g., coffee shops around another station in the same city). The advent of crowdsourced data from devices and services carried by individuals on a daily basis has opened up the possibility of performing better predictions of temporal visitation...

Complexity Digest wrote a new blog post titled Cooperative Object Transport in Multi-Robot Systems: A Review of the State-of-the-Art
In recent years, there has been a growing interest in designing multi-robot systems (hereafter MRSs) to provide cost effective, fault-tolerant and reliable solutions to a variety of automated applications. Here, we review recent advancements in MRSs specifically designed for cooperative object transport, which requires the members of MRSs to coordinate their actions to transport objects from a starting position to a final destination. To achieve cooperative object transport, a wide range of transport, coordination and control strategies have been proposed. Our goal is to provide a...

Complexity Digest wrote a new blog post titled The Human Takeover: A Call for a Venture into an Existential Opportunity
We propose a venture into an existential opportunity for establishing a world ‘good enough’ for humans to live in. Defining an existential opportunity as the converse of an existential risk—that is, a development that promises to dramatically improve the future of humanity—we argue that one such opportunity is available and should be explored now. The opportunity resides in the moment of transition of the Internet—from mediating information to mediating distributed direct governance in the sense of self-organization. The Internet of tomorrow will mediate the execution of contracts,...

Complexity Digest wrote a new blog post titled When Robots Get Bored and Invent Team Sports: A More Suitable Test than the Turing Test?
Increasingly, the Turing test—which is used to show that artificial intelligence has achieved human-level intelligence—is being regarded as an insufficient indicator of human-level intelligence. This essay extends arguments that embodied intelligence is required for human-level intelligence, and proposes a more suitable test for determining human-level intelligence: the invention of team sports by humanoid robots. The test is preferred because team sport activity is easily identified, uniquely human, and is suggested to emerge in basic, controllable conditions. To expect humanoid...

Complexity Digest wrote a new blog post titled Will the New Ring Vaccination Stop the Spread of Ebola?
The World Health Organization (WHO) and news reports are describing the deployment of a new experimental vaccine for Ebola in the Democratic Republic of the Congo (DRC). Originally 4,000 doses were sent to the country, and while the number is growing to 8,000 or more, there are still not enough to widely inoculate the city of Mbandaka with a population of over a million. Reports describe how the vaccine will be used in a "ring vaccination" technique. In ring vaccination, those who are most likely to be infected receive the vaccine. Currently this is being done by inoculating...

Complexity Digest wrote a new blog post titled Symbolic Unity, Dynastic Continuity, and Countervailing Power: Monarchies, Republics, and the Economy
We investigate the implications of the persistence of traditional patterns of state organization by examining the relationship between property rights and the economy for monarchies and republics. We argue that, relative to republics, monarchies protect property rights to a greater extent by reducing the negative effects of internal conflict, executive tenure, and executive discretion. In turn, a better protection of property rights results in greater standards of living. Using panel data on 137 countries between 1900 and 2010, we formulate and test a model with endogenous variables....
