Computational Network Biology. Physics Reports. December, 2019. A seven member international team posted in China, Switzerland and the USA (Ruth Nussinov, National Cancer Institute) provide an 80 page tutorial across scientific techniques and real applications as life’s intricate anatomy and physiology becomes understood by these revolutionary 2010s features. Biological entities are involved in intricate and complex interactions, in which uncovering the biological information from the network concepts are of great significance. In this review, we summarize the recent developments of this vital, copious field, first introducing various types of biological network structural properties. We then review the networkbased approaches, ranging from metrics to machinelearning methods, and how to use these algorithms to gain new insights. We highlight the application in neuroscience, human disease, and drug developments and discuss some major challenges and future directions. (Abstract excerpt) Liu, JinLong, et al. Fractal and Multifractal Analyses of Bipartite Networks. Nature Scientific Reports. 7/45588, 2017. As nature’s webworks from condensed matter to Internet cultures become evident and quantified, Key Laboratory of Intelligent Computing and Information Processing of Ministry of Education and Hunan Key Laboratory for Computation and Simulation in Science and Engineering, Xiangtan University, China researchers finesse their iconic complexities. Our interest is then a pervasive presence of a universal repetition in kind of one common code motif comprised of archetypal nodal and connective (gender) complements. See also for example in this journal SO2 Emissions in China – Their Network and Hierarchical Structures for another take (Shaomin Yan & Guang Wu, 2017). Bipartite network, as a special kind of complex networks, has also attracted a great deal of attention from researchers in the fields of scientific research, engineering application, ecommerce, etc. The difference with the unipartite networks is the fact that the nodes of a bipartite network can be separated into two classes and its edges exist only between nodes of different classes. In real world, there are many systems, which can be modeled naturally by a bipartite network, such as the metabolic network, the human sexual network, actormovie network, scientistpaper network, webuser network, and so on.

Six theorists from Chinese Universities and Rensselaer Polytechnic Institute including Jianxi Gao and Boleslaw Szymanski post a 113 page, 859 reference 2020 tutorial about this pervasive ability of natural node/link complexities to restore and maintain themselves. Typical sections are Tipping Points in Ecological Networks, Phase Transitions in Biological Networks, Behavior Transitions in Animal and Human Networks and Resilience, Robustness and Stability. In the midst of epochal perils, this entry reports a concurrent worldwise finding of a revolutionary genesis ecosmos with its own bigender genomic code. Many systems on our planet are known to shift abruptly and irreversibly from one state to another when they are forced across a "tipping point," such as mass extinctions in ecological networks, cascading failures in infrastructure systems, and social convention changes in human and animal networks. Such a regime shift demonstrates a system's ability to adjust activities so to retain its basic functionality in the face of internal or external changes. Only in recent years by way of network theory and lavish data sets, have complexity scientists been able to study realworld multidimensional systems, early warning indicators and resilient responses. This report reviews resilience function and regime shift of complex systems in domains such as ecology, biology, social systems and infrastructure.

Reported more in Universality, Coventry University physicists apply condensed matter theories in the form of complex systems to the historic corpus of epic fabled and storied mythic literatures. The second quote is a also exemplifies how such papers now open as the range and reach of nonlinear phenomena extends across every natural and social domain. As a result, a true cosmos to culture “universality” is at last becoming evident and proven. Mariani, Manuel, et al. Nestedness in Complex Networks: Observation, Emergence, and Implications. Physics Reports. Volume 813, 2019. Ecological theorists based in China and Switzerland including Jordi Bascompte post a 140 page, 400 reference affirmation of nature’s evolutionary developmental genesis, as long sensed, by way of combining smaller entities (biomolecules, cells, species) within larger, reciprocally beneficial, whole systems. Akin to the major transitions scale and others, life’s long recurrent emergence from microbes to meerkats to a metropolis gains its 2020 sophisticated mathematical quantification. The observed architecture of ecological and socioeconomic networks differs significantly from that of random networks. From a network science standpoint, nonrandom structural patterns observed in real networks calls for an explanation of their emergence and systemic consequences. This article focuses on one of these patterns: nestedness. Given a network of interacting nodes, nestedness is a tendency for nodes to interact with subsets of the interaction partners of betterconnected nodes. Nestedness has been found in diverse as ecological mutualistic organizations, world trade, interorganizational relations, among many other areas. We survey results from variegated disciplines, including statistical physics, graph theory, ecology, and theoretical economics. (Abstract excerpt) Masucci, Adolfo, et al. Extracting Directed Information Flow Networks. Physical Review E. 83/026103, 2011. Researchers from Spain and Greece identify a universally applicable, seemingly independent, feature of complex systems in repetitive evidence across widely separate domains of genomic webs and the worldwide web. See also Masucci, et al “Wikipedia Information Flow Analysis Reveals the ScaleFree Architecture of the Semantic Space” in PLoS One (6/2, 2011). We introduce a general method to infer the directional information flow between populations whose elements are described by ndimensional vectors of symbolic attributes. The method is based on the JensenShannon divergence and on the Shannon entropy and has a wide range of application. We show here the results of two applications: first we extract the network of genetic flow between meadows of the seagrass Poseidonia oceanica, where the meadow elements are specified by sets of microsatellite markers, and then we extract the semantic flow network from a set of Wikipedia pages, showing the semantic channels between different areas of knowledge.

An Ibaraki University, Japan mathematician proposes an affinity of universal selfsimilarity with nature’s propensity to seek and favor this most effective viable poise. See also Fractality and Degree Correlations in ScaleFree Networks in the European Physical Journal B (90/Art. 126, 2017). In this paper, a simple dynamical model in which fractal networks are formed by selforganized critical (SOC) dynamics is proposed; the proposed model consists of growth and collapse processes. It has been shown that SOC dynamics are realized by the combined processes in the model. Thus, the distributions of the cluster size and collapse size follow a powerlaw function in the stationary state. Moreover, through SOC dynamics, the networks become fractal in nature. The criticality of SOC dynamics is the same as the universality class of meanfield theory. The model explains the possibility that the fractal nature in complex networks emerges by SOC dynamics in a manner similar to the case with fractal objects embedded in a Euclidean space.

RM, Dounia Lotfi, and Mohamed El Marraki, Mohammed V University, Rabat, Morocco and Joyati Debnath, Winona State University, USA mathematicians post a sophisticated description of nature’s innate geometries. While invisible, their linkages are truly present as they unite and vivify all the overt objects and entities. Enumerating all the spanning trees of a complex network is theoretical defiance for mathematicians, electrical engineers and computer scientists. In this article, we propose a generalization of the Fractal ScaleFree Lattice and study its structural properties. As its degree distribution follows a power law, we prove that the proposed generalization does not affect the scalefree property. In addition, we use equivalent transformations to count the number of spanning trees in the generalized Fractal ScaleFree Lattice. Finally, in order to evaluate the robustness of the generalized lattice, we compute and compare its entropy with other complex networks. (Abstract) Molkenthin, Nora and Marc Timme. Scaling Laws in Spatial Network Formation. Physical Review Letters. 117/168301, 2016. While many papers nowadays report a specific instance of complex systems (galaxies, brains, language), herein MPI Network Dynamics and SelfOrganization physicists distill an independent, universally recurrent constancy which can be seen to take on selfsimilar forms and flows everywhere. Geometric constraints impact the formation of a broad range of spatial networks, from amino acid chains folding to proteins structures to rearranging particle aggregates. How the network of interactions dynamically selforganizes in such systems is far from fully understood. Here, we analyze a class of spatial network formation processes by introducing a mapping from geometric to graphtheoretic constraints. Combining stochastic and mean field analyses yields an algebraic scaling law for the extent (graph diameter) of the resulting networks with system size, in contrast to logarithmic scaling known for networks without constraints.

University of Zaragoza, Spain and University of Maribor, Slovenia physicists open a special collection with this title, as the quote notes. We note, for example, InterLayer Competition in Adaptive Multiplex Network by Elena Pitsik (20/075004) and Communicability Geometry of Multiplexes by Ernesto Estrada (21/015004, 2019). In the later past century and early 2000's, the availability of data about realworld systems made it possible to study the topology of large networks. This work has revealed the structure, dynamics and functions of complex networks, as well as new models for synthetic networks. During the last 5 years, also backed up by new results, scientists have realized that many systems and processes cannot be described with singlelayer nets since they have a multilayer geometry made up of many layers. The study of these multiplex networks has pointed out that their structure, dynamics, and evolution exhibit nontrivial relationships and interdependencies that give rise to new phenomena. (Scope) Motter, Adilson and Yang Yang. The Unfolding and Control Network Cascades. Physics Today. January, 2017. A Northwestern University astrophysicist and a biochemical engineer initially record how these active interconnective topologies have now been found to occur throughout nature and society. As a result, generic, universally applicable structures and dynamics, e.g. neural net behavior, can be distilled. Because they are so pervasive and important the paper proposes novel ways for their salutary management. See concurrently Understanding the Controllability of Complex networks from the Microcosmic to the Macrocosmic by Peng Sun and Xiaoke Ma in the New Journal of Physics (19/013022, 2017), and Networks in Motion by Motter and Reka Albert in Physics Today (April 2012). A characteristic property of networks is their ability to propagate influences, such as infectious diseases, behavioral changes, and failures. An especially important class of such contagious dynamics is that of cascading processes. These processes include, for example, cascading failures in infrastructure systems, extinctions cascades in ecological networks, and information cascades in social systems. In this review, we discuss recent progress and challenges associated with the modeling, prediction, detection, and control of cascades in networks. Mulder, Daan and Ginestra Bianconi. Network Geometry and Complexity. arXiv:1711.06290. Queen Mary University of London mathematicians continue their project (search GB) to express a common, independent network form and function in a way that can be given a nonlinear, nonequilibrium physical basis. See also NonEuclidean Geometry in Nature by Sergei Nechaev at 1705.08013. Recently higher order networks describing the interactions between two or more nodes are attracting large attention. Most notably higher order networks include simplicial complexes formed not only by nodes and links but also by triangles, tetrahedra, etc. glued along their faces. Simplicial complexes and in general higher order networks are able to characterize data as different as functional brain networks or collaboration networks beyond the framework of pairwise interactions. Interestingly higher order networks have a natural geometric interpretation and therefore constitute the natural way to explore the discrete network geometry of complex networks. Here we investigate the rich interplay between emergent network geometry of higher order networks and their complexity in the framework of a nonequilibrium model called Network Geometry with Flavor.
