4. Universality Affirmations: A Critical Complementarity
Plenz, Dietmar, et al. Self-Organized Criticality in the Brain. . . Into the 2020s, National Institute of Mental Health, Critical Brain Dynamics Section (D. Plenz director, search) neuroscientists report on a decade and more of convergent research findings which now have reached a proven validity that human cerebral activity does indeed seek and reside at an optimum dynamic poise. In respect, one more robust exemplar, on the way to an invariant universality, is achieved by virtue of our own microcosmic cognizance. The paper also appears in Frontiers in Physics for July 2021.
Self-organized criticality (SOC) refers to the ability of complex systems to evolve towards a phase transition at which interactions between system components lead to scale-invariant events beneficial for overall performance. For the last two decades, considerable experimental evidence has accumulated that the mammalian cortex with its diversity in cell types, interconnectivity, and plasticity might exhibit SOC. Here we review experimental findings of isolated, layered cortex preparations to self-organize towards the four dynamical motifs of up-states, oscillations, neuronal avalanches, and coherence potentials. The precise interaction between up-states, nested oscillations and avalanches in layered cortex provides compelling evidence for SOC in the brain. (Abstract excerpt)
Poirot, Olivier and Youri Timsit. Neuron-Like Networks between Ribsomal Proteins within the Ribosome. Nature Scientific Reports. 6/26485, 2016. We report this entry by Information Génomique et Structurale CNRS, Aix-Marseille Université researchers as an example of the 2016 historic synthesis in our global collaborative midst. At once, it shows how the archetypal scale-free networks found from cosmic webs to literary classics also appears in protein phenomena. This iconic universality is then seen as akin to neural net node and link informational activities.
The Ribosome is a minute particle consisting of RNA and associated proteins, found in large numbers in the cytoplasm of living cells. They bind messenger RNA and transfer RNA to synthesize polypeptides and proteins.
Qian, Xiao-Feng, et al. Bohr’s Complementarity: Completed with Entanglement. arXiv:1803.04611. University of Rochester physicists X-F Qian, A. Vamivakas, and Joseph Eberly arrive at a current mathematical resolve by way of a triune synthesis of mutual exclusivity and an integral composite. Octogenarian Eberly has been a lifetime theorist for optical quantum phenomena. See also Shifting the Quantum-Classical Boundary by this team in Optica (2/7, 2015).
Ninety years ago in 1927 at an international congress in Como, Italy, Niels Bohr gave an address which is recognized as the first instance in which the term "complementarity" was spoken publicly. Bohr had accepted duality as a principle of physics: close observation of any quantum object will reveal either wave-like or particle-like behavior, one or the other of two fundamental and complementary features. Some confusion followed his talk and complementarity has seen much discussion since but the concept retains a central place in quantum mechanics. Scholarly examinations provide speculations about the relevance of complementarity in fields as different from physics as biology, psychology and social anthropology. In regard, recent approaches by our group and others seem to show that entanglement is the ingredient needed to complete Bohr's formulation. (Abstract edits)
Reina, Andreagiovanni, et al. Psychophysical Laws and the Superorganism. Nature Scientific Reports. 8/4387, 2018. As a good instance for this section, University of Sheffield and ISTC, Italian National Research Council computational psychologists discern a consistence recurrence in kind across a wide array of creaturely phyla. Furthermore, a similar correspondence holds for both somatic physiologies and cerebral functions. By these lights, a common evolutionary track of individual organisms into viable communal forms becomes evident, as enhanced by intelligent capacities.
A large number of organisms at diverse levels of biological complexity, from humans to unicellular moulds, obey the same psychophysical laws that characterise the relationship between stimuli and the organism’s response. This study shows for the first time that groups of individuals, in our case honeybee colonies, considered as a single superorganism, might also be able to obey the same laws. Similarly to neurons, no individual explicitly encodes in its simple actions the dynamics determining the psychophysical laws; instead it is the group as a whole that displays such dynamics. The observed similarities in stimuli response between brain and superorganism motivate further investigations of collective behaviour through the lens of cognitive science and psychology. Research synergies between neuroscience and collective intelligence studies can highlight analogies that could
Rocha, Rodrigo, et al. Homeostatic Plasticity and Emergence of Functional Networks in a Whole-Brain Model at Criticality. Nature Scientific Reports. 8/15682, 2018. After a decade of theory and test, University of Padova. Italy biophysicists including Samir Suweis and Amos Maritan contribute to current conclusions that dynamic cerebral network cognition does indeed reside in a self-organized, critically balanced state between control and creativity.

Understanding the relationship between large-scale structural and functional brain networks remains a crucial issue in modern neuroscience. Recently, there has been growing interest in investigating the role of homeostatic plasticity mechanisms in regulating network activity and brain functioning against a wide range of environmental conditions and brain states. In the present study, we investigate how the inclusion of homeostatic plasticity in a stochastic whole-brain model, implemented as a normalization of the incoming node’s excitatory input, affects the macroscopic activity during rest and the formation of functional networks. In this work, we show that normalization of the node’s excitatory input improves the correspondence between simulated neural patterns of the model and various brain functional data. Our results suggest that the inclusion of homeostatic principles lead to more realistic brain activity consistent with the hallmarks of criticality. (Abstract)
Roli, Andrea, et al. Dynamical Criticality. Journal of Systems Science and Complexity. 31/3, 2018. In this Springer journal, University of Bologna, University of Modena, and European Centre for Living Technology researchers including Marco Villani (search for more papers) contribute to realizations that nature’s persistently seems to seek and balance at an optimum complementary state between reliable stability and free creativity. See also Concepts in Boolean Network Modeling by Julian Schwab, et al (2020) in Universal Principles.
Systems that exhibit complex behaviours are often found in a particular dynamical condition, poised between order and disorder. This observation is at the core of the so-called criticality hypothesis, which states that systems in this dynamical regime attain the highest level of computational capabilities and achieve an optimal trade-off between robustness and flexibility. Recent results in cellular and evolutionary biology, neuroscience and computer science have strengthened the criticality hypothesis, and its role as a candidate general law in adaptive complex systems. We provide an overview of the works on dynamical criticality that are, to the best of our knowledge, particularly relevant for the criticality hypothesis, such as dynamics and information processing at the edge of chaos. In regard, we illustrate the main achievements in the study of critical dynamics in biological systems. (Abstract edits)
Rulands, Steffen, et al. Universality of Clone Dynamics during Tissue Development. Nature Physics. 14/5, 2018. We recall hardly a decade ago when cellular self-organization was just a glimmer. For this ten person team from Cambridge University and the Free University of Brussels, it has become a tacit, intrinsic paradigm of creative effect across life’s developmental physiology., to which they contribute. In regard, systemic tendencies to reach a critical poise are reported, akin to other fields such as neuroscience, which are then traced to condensed matter physical energies. The entry can stand as iconic evidence for an imminent 21st century consonant genesis synthesis.
The emergence of complex organs is driven by the coordinated proliferation, migration and differentiation of precursor cells. The fate behaviour of these cells is reflected in the time evolution of their progeny, termed clones, which serve as a key experimental observable. But what can be learnt from clonal dynamics in development, where the spatial cohesiveness of clones is impaired by tissue deformations during tissue growth? Drawing on the results of clonal tracing studies, we show that, despite the complexity of organ development, clonal dynamics may converge to a critical state characterized by universal scaling behaviour of clone sizes. Our study shows the emergence of core concepts of statistical physics in an unexpected context, identifying cellular systems as a laboratory to study non-equilibrium statistical physics. (Abstract)
Santos, Vagner, et al. Riddling: Chimera’s Dilemma. Chaos. 28/081105, 2018. State University of Ponta Grossa, Brazil, Potsdam Institute for Climate Impact Research, University of Aberdeen, Xian University of Technology, and Federal University of Paraná, Brazil researchers including Jurgen Kurths provide a general analysis of nature’s pervasive propensity to seek and reside in a dynamic duality of more and less orderly states at the same time. Life and mind increasingly seem to be attracted to and prefer this optimum condition in every case from quantum to cerebral phases.
We investigate the basin of attraction properties and its boundaries for chimera states in a circulant network of Hénon maps. It is known that coexisting basins of attraction lead to a hysteretic behaviour in the diagrams of the density of states as a function of a varying parameter. Chimera states, for which coherent and incoherent domains occur simultaneously, emerge as a consequence of the coexistence of basin of attractions for each state. Consequently, the distribution of chimera states can remain invariant by a parameter change, and it can also suffer subtle changes when one of the basins ceases to exist. A similar phenomenon is observed when perturbations are applied in the initial conditions. By means of the uncertainty exponent, we characterise the basin boundaries between the coherent and chimera states, and between the incoherent and chimera states. This way, we show that the density of chimera states can be not only moderately sensitive but also highly sensitive to initial conditions. This chimera’s dilemma is a consequence of the fractal and riddled nature of the basin boundaries. (Abstract)
Satz, Helmut. Self-Organized Criticality. arXiv:2003.08130. This is an invited talk at the 40th Max-Born-Symposium, Wroclaw/Poland in October 2019 by the University of Bielefeld, Germany physicist. Its brief summary is We apply the concept of self-organized criticality in statistical physics to the study of multihadron production in high energy collisions. As its first paragraph below says, the posting is another notice of nature’s preferential occasion and resolve at this optimum balance at every such instantiation.
(Per) Bak went on to ask: How can the universe start with a few types of elementary particles at the big bang, and end up with life, history, economics and literature? Why did the big bang not form a simple gas of particles or condense into one big crystal? In other words, the issue was to understand how the structured complexity of the world around us could arise. Thus, new concepts of the past twenty years are emergence, complexity, fractality, chaos; non-equilibrium behavior, self-organization. In physics, this has led to intensive studies of emergent phenomena in non-equilibrium processes, and in mathematics to fractal structures. It has also led to a general framework applicable to swarm formation in biology and to financial market patterns. In this talk, I want to show how it can provide a new view of multihadron production in high energy collisions. (1-2)
Scheffer, Marten, et al. Inequality in Nature and Society. Proceedings of National Academy of Sciences. 114/13154, 2017. Wageningen University ecologists and a Utrecht University historian describe another independent, recurrent pattern of animal and human groupings across scales which reverts to a relatively rich, privileged few and poor, wretched masses. But the higher the stage, such as a nation, the harder it becomes to intentionally correct, mitigate and level out for mutual, palliative benefit.
Inequality is one of the main drivers of social tension. We show striking similarities between patterns of inequality between species abundances in nature and wealth in society. We demonstrate that in the absence of equalizing forces, such large inequality will arise from chance alone. While natural enemies have an equalizing effect in nature, inequality in societies can be suppressed by wealth-equalizing institutions. However, over the past millennium, such institutions have been weakened during periods of societal upscaling. Our analysis suggests that due to the very same mathematical principle that rules natural communities (indeed, a “law of nature”) extreme wealth inequality is inevitable in a globalizing world unless effective wealth-equalizing institutions are installed on a global scale.

Schlapfer, Markus, et al. The Hidden Universality of Movement in Cities. arXiv:2002.06070. Santa Fe Institute, MIT, ETH Zurich, and University of Copenhagen theorists including Geoffrey West consider urban intensities such as social media, innovation, productivity, epidemics and much more across four continents. As this project to treat cities as complex fractal systems reaches two decades, it is now possible to robustly confirm the presence of common mathematic spatial patterns and temporal dynamics. Once more this year, an unseen generative invariance every case and place becomes quite apparent. As other planners variously perceive, our larger and smaller human habitations gain a predictability and preference which can be availed for betterment. See also The Spectral Dimension of Human Mobility by this group at 2002.06740.
The interaction of all mobile species within an environment hinges on their movement patterns. In human society, where the prevalent form of cohabitation is in cities, the dynamic and diverse movement of people affects every aspect of socio-economic life and the evolution of urban infrastructure, productivity, innovation and technology. However, the laws that govern the variation of population flows to specific locations have remained elusive. Here we show that behind their apparent complexity a simple universal scaling relation drives the flow of individual based on both frequency of visitation and distance travelled. We demonstrate that population flows obey this theoretical prediction in all tested areas across the globe, ranging from Europe and America to Asia and Africa, regardless of the geographies, cultures or levels of development.

Sherman, Nicholas, et al. Universality of Critical Dynamics with Finite Entanglement. 2301.09681. An example of 2023 integrative frontiers as UC Berkeley physicists find a 21st century quantum organics to be robustly distinguished by critically poised states for optimum performance across a wide array of occasions and applications. At the same while, we post Fish Shoals Resemble a Stochastic Excitable System (Gomez-Nava) about similar criticalities which grace and serve animal groups. So in this discovery year, our Earthwise pedia sapience is indeed finding proof of nature’s innate preference everywhere.
When a system is swept through a quantum critical point, the quantum Kibble-Zurek mechanism makes universal predictions for the number and energy of excitations produced. In this work, we study how low-energy dynamics of quantum systems near criticality are modified by finite entanglement, using invariant critical points. Our result establishes the precise role played by entanglement in time-dependent critical phenomena and has direct implications for quantum state preparation and classical simulation of quantum states.
