Bizzarri, Mariano, et al. Complexity in Biological Organization: Key Concepts. Entropy. Online August 12, 2020. In a special Biological Statistical Mechanics issue, systems scientists from Italy, Russia and Cuba, surely a global online faculty, post a 21st century retrospective of advance, emphasis, clarification and convergence in this wide ranging study of nature’s nonlinear essence. The paper first reviews etymology origins of key concepts and terms within this organic revolution – complexity, systems, self-organization, emergence, hierarchy and so on. Renormalization theory, critical transitions and more also receive notice as a revolutionary organic universe to human genesis gains witness, articulation and credence.
The “magic” word complexity evokes a multitude of meanings that obscure its real sense. Here we try and generate a bottom-up reconstruction of the deep sense of complexity by looking at the convergence of different features shared by complex systems. We specifically focus on complexity in biology but stressing the similarities with analogous features encountered in inanimate and artifactual systems in order to track an integrative path toward a new “mainstream” of science overcoming the actual fragmentation of scientific culture.

Bonchev, Daniel and Dennis Rouvray, eds. Complexity in Chemistry, Biology, and Ecology. Berlin: Springer, 2005. An increasing number of works are seeking in diverse areas a common denominator and terminology for complex systems behavior. (see Chua below) Earlier on studies focused on a certain aspect such as network geometry or active agents. But all this goes on without examining what kind of universe such phenomena might spring from. So any organic organization remains couched in mechanistic verbiage. This text at once contributes new insights but is caught in this conflation.
The contemporary scientific method is built on reductionism. The surprising finding that this paradigm has limits gave rise to the concept of complexity. This book presents the new science of complexity by presenting diverse concepts from the analyses of a wide range of real world systems (chemical, biochemical, biological, and ecological). Based on a variety of approaches ranging from cellular automata and dynamic evolutionary networks to topology and information theory, the book contains methodologies of practical importance for assessing systems complexity and network analysis in medicine and biology.

Bornholdt, Stefan and Stuart Kauffman. Ensembles, Dynamics, and Cell Types: Revisiting the Statistical Mechanics Perspective on Cellular Regulation. arXiv:1902.00483. University of Bremen and Institute for Systems Biology, Seattle senior theorists look back 50 years to review Kauffman’s 1969 paper Metabolic Stability and Epigenesis in Randomly Constructed Genetic Nets (Journal of Theoretical Biology, 22/3, Abstract below). His 1993 work The Origins of Order played a major part in establishing the field of complex system studies. This posting continues its Self-Organization and Selection in Evolution subtitle by adding a statistical mechanics basis for biological regulation, along with selective effects. Into 2019 his prescient glimpses are well proven as we now know that gene regulatory networks do seek a self-organized criticality (search Bryan Daniels, Universality, Autocatalytic sections and elsewhere).
Genetic regulatory networks control ontogeny. For fifty years Boolean networks have served as models of such systems, ranging from ensembles of random Boolean networks as models for generic properties of gene regulation to working dynamical models of a growing number of sub-networks of real cells. At the same time, their statistical mechanics has been thoroughly studied. Here we recapitulate their original motivation in the context of current theoretical and empirical research. We discuss ensembles of random Boolean networks whose dynamical attractors model cell types. There is now strong evidence that genetic regulatory networks are dynamically critical, and that evolution is exploring the critical sub-ensemble. The generic properties of this sub-ensemble predict essential features of cell differentiation. Thus, the theory correctly predicts a power law relationship between the number of cell types and the DNA contents per cell, and a comparable slope. (2019 Abstract excerpt)
Bountis, Tassos, et al. The Science of Complexity and the Role of Mathematics. European Physical Journal Special Topics. 225/883, 2016. Greek and British systems theorists introduce a special issue on this title subject. As the quotes say, and this site documents, as these endeavors reach a broad veracity, we ought to avail their wider natural, social and global benefit. And how appropriate that some two millennia later, such a scientific and philosophical advance comes from mainly Greece. If this robust 21st century natural knowledge can be translated, understood, and put to practical service, we might be able to resolve a local and global free-fall into economic, political, and internecine chaos. Sadly their own country is a prime example. Some papers are Regular and Chaotic Orbits in the Dynamics of Exoplanets, Hypernetworks, and Controlled Aggregation in Complex Systems.

In the middle of the second decade of the 21st century, Complexity Science has reached a turning point. Its rapid advancement over the last 30 years has led to remarkable new concepts, methods and techniques, whose applications to complex systems of the physical, biological and social sciences has produced a great number of exciting results. The approach has so far depended almost exclusively on the solution of a wide variety of mathematical models by sophisticated numerical techniques and extensive simulations that have inspired a new generation of researchers interested in complex systems. Still, the impact of Complexity beyond the natural sciences, its applications to Medicine, Technology, Economics, Society and Policy are only now beginning to be explored. Furthermore, its basic principles and methods have so far remained within the realm of high level research institutions, out of reach of society’s urgent need for practical applications.

The text, and burgeoning project, is another sign of the broad historical shift to better understand and guide human societies by way of these palliative organic vitalities.
The new science of complex systems is providing radical new ways of understanding, modeling, predicting, managing the physical, biological, ecological, and social universe. Complex systems are characterised by emergent structures that occur in many domains and questions that apply across the domains in the modern world. Radical new strategies of research and teaching are necessary for all the previous transversal questions through all kind of complex systems, from atoms to complex matter, from the molecules to organisms, from organisms to the ecosphere, from neurotransmitters to the individual and social cognition, from individuals to human society. This huge effort is necessary for reconstructing the observed multi-scale dynamics relevant for the “human scales” in between the physics of the two infinites, the nuclear physics in one side and the cosmology in the other side.
Brauns, Fridtjof, et al. Phase-Space Geometry of Reaction-Diffusion Dynamics. arXiv:1812.08684. In a densely technical, tightly composed 55 page paper, Ludwig-Maximilians University system physicists FB, Jacob Halatek and Erwin Frey (search) continue their decadal project to explain by way of nonequilibrium thermodynamics, structural formations, Turing-like morphogenesis, self-organized critical complexities, computational biology, and more how life proceeds to develop and maintain its physiological vitality. With 158 references, in these later 2010s a collaborative sense of a realistic model is evident. It is proposed in closing that such cellular coherence is an generalization which could apply to other natural systems.

Experimental studies of protein pattern formation have stimulated new interest in the dynamics of reaction--diffusion systems. However, a comprehensive theoretical understanding of the dynamics of such highly nonlinear, spatially extended systems is still missing. Here we show how a description in phase space, which has proven invaluable in shaping our intuition about the dynamics of nonlinear ordinary differential equations, can be generalized to mass-conserving reaction--diffusion (McRD) systems. We present a comprehensive theory for two-component McRD systems, which serve as paradigmatic minimal systems. The fundamental elements of the theory presented suggest ways of experimentally characterizing pattern-forming systems on a mesoscopic level and are generalizable to a broad class of spatially extended non-equilibrium systems, and thereby pave the way toward an overarching theoretical framework.

Brown, Barton, et al. Dynamically Generated Hierarchies in Games of Competition. arXiv.1906.01383. By way of our philoSophia approach, Virginia Tech physicists and a Jacobs University, Bremen physicist (Hildegard Meyer-Ortmanns) can be seen to achieve a quantified description of intrinsic natural “spontaneities” which evidently form on into complex, interactive, beneficial groupings.
Spatial many-species predator-prey systems have been shown to yield very rich space-time patterns. This observation begs the question whether there exist universal mechanisms for generating such emerging complex patterns in non-equilibrium systems. In this work we investigate the possibility of dynamically generated hierarchies in predator-prey systems. We analyze a nine-species model with competing interactions and show that the situation results in the spontaneous formation of spirals within spirals. As cyclic interactions occur spontaneously in systems with competing strategies, the mechanism discussed in this work should contribute to our understanding of various social and biological systems.

Life is amazing. Even the smallest bacterium is far more complex in its structure and function than any known physical system. The largest, most complex organisms, large mammals and giant trees, weigh more than 21 orders of magnitude more than the simplest microbes, yet they use basically the same molecular structures and biochemical pathways to sustain and reproduce themselves.

The Earth’s surface and the living things that inhabit it are incredibly diverse….Underlying this enormous physical and biological diversity, however, are emergent patterns that are precise, quantitative, and universal or nearly so. (619)
Buchanan, Mark. Ubiquity: Why the World Is Simpler Than We Think. London: Weidenfeld & Nicolson, 2000. An accessible introduction to how the nonlinear sciences reveal a “universality” in nature and history. The same patterns and processes are in evidence from cosmic origins to world civilization and economic society because they spring from an independent dynamics of power laws and self-organized criticality.
Cavalcante, Hugo, et al. Predictability and Control of Extreme Events in Complex Systems. arXiv:1301.0244. In this January 2013 posting, systems physicists Cavalcante and Marcos Oria, Universidade Federal da Paraiba, Brazil, Didier Sornette, ETH Zurich, and Daniel Gauthier, Duke University, provide further quantitative support for the theories of Sornette (search) and colleagues that warning signs of impending catastrophic calamities can in fact be limned from hyper-complexities such as climates and economies, contrary to many denials. These significance insights are also well explained by mathematician James Weatherall in his fine The Physics of Wall Street: A Brief History of Predicting the Unpredictable (Houghton Mifflin Harcourt, 2013)
In many complex systems, large events are believed to follow power-law, scale-free probability distributions, so that the extreme, catastrophic events are unpredictable. Here, we study coupled chaotic oscillators that display extreme events. The mechanism responsible for the rare, largest events makes them distinct and their distribution deviates from a power-law. Based on this mechanism identification, we show that it is possible to forecast in real time an impending extreme event. Once forecasted, we also show that extreme events can be suppressed by applying tiny perturbations to the system. (Abstract)
Chandler, Jerry and Gertrudis Van de Vijver, eds. Closure: Emergent Organizations and Their Dynamics. New York: New York Academy of Sciences. Volume 901, 2000. Many articles consider autopoietic processes with regard to their property of constantly forming, describing and "closing" their “biosemiotic” identity. This is a sign-based organic viability which pervades the natural realm as living systems refer to and enhance their own internal definition and individuality.
