Chavalarias, David. From Inert Matter to the Global Society: Life as Multi-level Networks of Processes. Philosophical Transactions of the Royal Society B. February, 2020. In this Unifying the Essential Concepts of Biological Networks issue, a Parisian cognitive scientist (bio below) illumes a cosmic to congress synthesis due to the generative activity of self-organization, autopoiesis, biocatalysis, recurrent scales, and more. This view leads a “triple closure” (see Abstract) made up of member components, active relations, and an integral unity. Life’s evolutionary basis and intent is then seen as a constant fulfillment of this iconic, triune whole. A consequentl rise of cerebral cognition, collective intelligence, and cultural learning can also be observed. As this universe to human course proceeds, our global phase is seen to be emerging into a “humanity-organism.” In closing, it is noted that this worldwide advance must not be left to chance, rather a common, informed, popular, concerted effort is imperative to bring to fruition.
A billion years have passed since the first life forms appeared. Since then, life has continued to form complex associations between emergent levels of interconnection. Advances in molecular chemistry and theoretical biology based on a systems view can now conceptualize life’s origins and complexity from three notions of closure: processes, autocatalysis and constraints. This integral paradigm can then trace the physical levels of the organization of matter from physics to biology and society without resorting to reductionism. The phenomenon of life thus becomes a contingent complexification until life emerges as a network of auto-catalytic process networks, organized in a multi-level manner. A living systems approach inevitably reflects on cognition; and on the deep changes that affects humanity by way of our cultural evolution. (Abstract Excerpt)
Cimini, Giulio, et al. The Statistical Physics of Real-World Networks. arXiv:1810.05095. In a paper to appear in the new Nature Reviews Physics (2019), IMT School for Advanced Studies, Lucca, Italy researchers including Guido Caldarelli expand appreciations of nature’s universal complex nodal and relational networks. A widely separate yet integral rooting of our global civilization into physical condensed matter can then be achieved. An illustration displays how the same multiplex phenomena arises from a independent source which is exemplified from agriculture and industry to travel and trade.

Statistical physics is the natural framework to model complex networks. In the last twenty years, it has brought novel physical insights on a variety of emergent phenomena, such as self-organization, scale invariance, mixed distributions and ensemble non-equivalence, which cannot be deduced from individual constituents, along with information theory and the principle of maximum entropy. We review the statistical physics approach for complex networks and the null models for the various physical problems, focusing on the analytic frameworks reproducing the local features of the network. We show how these models have been used to detect statistically significant and predictive structural patterns in real-world networks. We further survey the statistical physics frameworks that reproduce more complex, semi-local network features using Markov chain Monte Carlo sampling, and the models of generalised network structures such as multiplex networks, interacting networks and simplicial complexes.

Systems physicists NC and Andrea Rapisarda, University of Catania, and Ginestra Bianconi, Queen Mary University of London continue to finely season nature’s true anatomy and physiology as it ever arrays in similar kinds from quantum to neuronal realms.
Growing network models have been shown to display emergent quantum statistics when nodes are associated to a fitness value describing the intrinsic ability of a node to acquire new links. Recently it has been shown that quantum statistics emerge also in a growing simplicial complex model called Network Geometry with Flavor which allow for the description of many-body interaction between the nodes. In this case the faces of the simplicial complex are naturally described by the Bose-Einstein, Boltzmann and Fermi-Dirac distribution depending on their dimension. We show that in this case the statistical properties of the faces of the simplicial complex are described by the Bose-Einstein or the Fermi-Dirac distribution only. (Abstract flavor)
Cohen, Reuven and Shlomo Havlin. Complex Networks: Structure, Robustness and Function.. Cambridge: Cambridge University Press;, 2010. A Bar-Ilan University, Israel mathematician and a physicist provide a comprehensive survey of ever growing realizations of an innately interconnected nature, organisms, and societies.
Examining important results and analytical techniques, this graduate-level textbook is a step-by-step presentation of the structure and function of complex networks. Using a range of examples, from the stability of the internet to efficient methods of immunizing populations, and from epidemic spreading to how one might efficiently search for individuals, this textbook explains the theoretical methods that can be used, and the experimental and analytical results obtained in the study and research of complex networks. Giving detailed derivations of many results in complex networks theory, this is an ideal text to be used by graduate students entering the field.
Costa, Luciano da Fontoura, et al. Analyzing and Modeling Real-World Phenomena with Complex Networks. Advances in Physics. 60/3, 2011. Drawing upon a departmental focus on this field, eight University of Sao Paulo physicists provide a 108 page survey, with 565 references, of this real dynamic materiality across nature and society. After noting Basic Concepts, topical areas are Social, Communications, Economy, Finance, Computers, Internet, World Wide Web, Citations, Transportation Power Grids, Biomolecular, Medicine, Ecology, Neuroscience, Linguistics, Earthquakes, Physics, Chemistry, Mathematics, Climate, and Epidemics – that is everywhere. From these many exemplars can be distilled a common, independent, complex system topology. Circa 2012, how could it dawn upon international collaborative science that this ubiquitous discovery is actually revealing a procreative genesis universe? In such regard, other such citations lately weigh in, e.g., Li and Peng in Complex Human Societies, Dorogovtsev, the Nature Physics Insight review, all herein, boding a critical credence. We append extended quotes.

Courtney, Owen and Ginestra Bianconi. Generalized Network Structures: The Configuration Model and the Canonical Ensemble of Simplicial Complexes. arXiv:1602.04110. Queen Mary University, London mathematicians employ this topological phrase for their perception of connective patterns commonly found across networks. After technicalities, generic, repetitive webs are defined which form and flow everywhere. See also such later postings as Centralities of Nodes and Influences of Layers in Large Multiplex Networks at 1703.05833, Weighted Growing Simplicial Complexes. 1703.01187, and Emergent Hyperbolic Network Geometry in Nature Scientific Reports (7/41974, 2017) which each have GB as a coauthor. Altogether these distinct, recurrent features would seem to imply and arise from a natural propensity.
Simplicial complexes are generalized network structures able to encode interactions occurring between more than two nodes. Simplicial complexes describe a large variety of complex interacting systems ranging from brain networks, to social and collaboration networks. Here we characterize the structure of simplicial complexes using their generalized degrees that capture fundamental properties of one, two, three or more linked nodes. We evaluate the entropy of these ensembles, finding the asymptotic expression for the number of simplicial complexes in the configuration model. We provide the algorithms for the construction of simplicial complexes belonging to the configuration model and the canonical ensemble of simplicial complexes. (Abstract)
Fast and Slow Thinking – of Networks.
As 2014 and 2015 additions to our Introduction convey, intensive research since the early 1990s to the mid 2010s has reached a phase of consolidation and universality. This posting by the Semmelweis University, Budapest, systems biochemist (search) is a synopsis of a book chapter Plasticity-Rigidity Cycles at arXiv:1511.01239, we both review together. In this contribution, the robust field of scale-free networks is shown to apply to these evolutionary and personal cognitive modes. The main reference is the popular 2011 book Thinking, Fast and Slow by Daniel Kahneman about the dual systems model, as reported in A Complementary Brain and Thought Process. A subtitle “The complementary ‘elite’ and ‘wisdom of crowds’ of amino acid, neuronal and social networks” cites a first rapid response core network that draws on past experiences. If inadequate for novel, unfamiliar inputs, a weakly linked cerebral periphery is activated, often with conflicting views.
Complex systems may have billion components making consensus formation slow and difficult. Recently several overlapping stories emerged from various disciplines, including protein structures, neuroscience and social networks, showing that fast responses to known stimuli involve a network core of few, strongly connected nodes. In unexpected situations the core may fail to provide a coherent response, thus the stimulus propagates to the periphery of the network. Here the final response is determined by a large number of weakly connected nodes mobilizing the collective memory and opinion, i.e. the slow democracy exercising the 'wisdom of crowds'. This mechanism resembles to Kahneman's "Thinking, Fast and Slow" discriminating fast, pattern-based and slow, contemplative decision making. The generality of the response also shows that democracy is neither only a moral stance nor only a decision making technique, but a very efficient general learning strategy developed by complex systems during evolution. The duality of fast core and slow majority may increase our understanding of metabolic, signaling, ecosystem, swarming or market processes, as well as may help to construct novel methods to explore unusual network responses, deep-learning neural network structures and core-periphery targeting drug design strategies.

Csermely, Peter. The Wisdom of Networks: A General Adaptation and Learning Mechanism of Complex Systems. BioEssays. Online November, 2017. The Semmelweis University, Budapest, medical chemist also advises that a salient feature of networks is their broad array into a faster, constrained detail, core area, (seeds or words), and a slower periphery (search term) capable of viewing a contextual field. While the rigid core keeps doing the same thing, the freer outliers are open to beneficial variations. Akin to Miguel Munoz and others, the paper cites many phases such as proteins, metabolic signaling, neural nets, ecosystems, and social media whence this independent, common trait is exemplified in kind. See also Structure and Dynamics of Core/Periphery Networks by P. Csermely, et al in Journal of Complex Networks (1/93, 2013).
I hypothesize that re-occurring prior experience of complex systems mobilizes a fast response, whose attractor is encoded by their strongly connected network core. In contrast, responses to novel stimuli are often slow and require the weakly connected network periphery. Upon repeated stimulus, peripheral network nodes remodel the network core that encodes the attractor of the new response. This “core-periphery learning” theory reviews and generalizes the heretofore fragmented knowledge on attractor formation by neural networks, periphery-driven innovation, and a number of recent reports on the adaptation of protein, neuronal, and social networks. Moreover, the power of network periphery-related “wisdom of crowds” inventing creative, novel responses indicates that deliberative democracy is a slow yet efficient learning strategy developed as the success of a billion-year evolution.

Csoma, Attila, et al. Routes Obey Hierarchy in Complex Networks. Nature Scientific Reports. 7/7243, 2017. As complex system studies proceed to fill in a multiplex multiverse, a ten person team from Budapest University of Technology and Economics, Eotvos Lorand University, Budapest, Indiana University, University Medical Center Utrecht, Lausanne University Hospital, and Lausanne Ecole Polytechnique discern a common presence across cerebral, transport, Internet, and word association games.

The last two decades of network science have discovered stunning similarities in the topological characteristics of real life networks (many biological, social, transportation and organizational networks) on a strong empirical basis. However our knowledge about the operational paths used in these networks is very limited, which prohibits the proper understanding of the principles of their functioning. Today, the most widely adopted hypothesis about the structure of the operational paths is the shortest path assumption. Here we present a striking result that the paths in various networks are significantly stretched compared to their shortest counterparts. Stretch distributions are also found to be extremely similar. This phenomenon is empirically confirmed on four networks from diverse areas of life. We also identify the high-level path selection rules nature seems to use when picking its paths. (Abstract)
D’Agostino, Gregorio and Antonio Scala. Networks of Networks: The Last Frontier of Complexity. International: Springer, 2014. As website entries convey, around 2014 a further appreciation of nature’s ubiquitous node and link topology arose that this topology actually comes as intricate nested layers, a multiplex. Italian systems physicists gather one of the first volumes about this advance. Typical chapters are Multiplex Networks by Kyu-Min Lee (search) et al, Networks of Interdependent Networks by Dror Kenett, et al, and Network Physiology by Plamen Evanov and Ronny Bartsch. See also Interconnected Networks, edited by Antonios Garas (Springer, 2014) for more.
The present work is meant as a reference to provide an organic and comprehensive view of the most relevant results in the exciting new field of Networks of Networks. Seminal papers have recently been published posing the basis to study what happens when different networks interact, thus providing evidence for the emergence of new, unexpected behaviors and vulnerabilities. From those seminal works, the awareness on the importance understanding Networks of Networks has spread to the entire community of Complexity Science. The contents have been aggregated under four headings; General Theory, Phenomenology, Applications and Risk Assessment. We are currently making the first steps to reduce the distance between the language and the way of thinking of the two communities of experts in real infrastructures and the complexity scientists.

A framework integrating information theory and network science is proposed, giving rise to a potentially new area. By incorporating and integrating concepts such as complexity, coding, topological projections and network dynamics, the proposed network-based framework paves the way not only to extending traditional information science, but also to modeling, characterizing and analyzing a broad class of real-world problems, from language communication to DNA coding. Basically, an original network is supposed to be transmitted, with or without compaction, through a sequence of symbols or time-series obtained by sampling its topology by some network dynamics, such as random walks. We show that the degree of compression is ultimately related to the ability to predict the frequency of symbols based on the topology of the original network and the adopted dynamics. (Abstract)
