In this book for the first time two scientific fields - consensus formation and synchronization of communications - are presented together and examined through their interrelational aspects, of rapidly growing importance. Both fields have indeed attracted enormous research interest especially in relation to complex networks. In networks of dynamic systems (or agents), consensus means to reach an agreement regarding a certain quantity of interest that depends on the state of all dynamical systems (agents). Consensus problems have a long history in control theory and computer sciences, and form the foundation of the field of distributed computing. Synchronization, which defines correlated-in-time behavior between different processes and roots going back to Huygens to the least, is now a highly popular, exciting and rapidly developing topic, with applications ranging from biological networks to mathematical epidemiology, and from processing information in the brain to engineering of communications devices. The book reviews recent finding in both fields and describes novel approaches to consensus formation, where consensus is realized as an instance of the nonlinear dynamics paradigm of chaos synchronization. The chapters are written by world-known experts in both fields and cover topics ranging from fundaments to various applications of consensus and synchronization.

For any group or organization to function effectively, it must be able to make decisions well. Consensus-Oriented Decision-Making is the first book to offer groups (and group facilitators) a clear and efficient path togenerating widespread agreement while fostering full participation and true collaboration. Poised to become the new standard for group facilitation, Consensus-Oriented Decision-Making combines: Deep insight into complex group dynamics Effective conflict resolution techniques Powerful communication skills. Groups using this simple, step-by step approach experience increased cohesion and commitment and stronger relationships as a result of their successful cooperation. Incorporating the principles of collaboration, inclusion, empathy, and open-mindedness, the CODM process encourages shared ownership of group decisions. The method can be used in any group situation, regardless of whether the final decision-making power rests with a single person or team, a vote of members, or unanimity. Business, government, non-profit, social and community organizations can all benefit from Consensus-Oriented Decision-Making. Whether you are a designated facilitator or an active participant, understanding this powerfulframework will help you contribute to the success of your group through achieving maximum participation and efficiency, a clearer decision-making process, better decisions, and improved group dynamics.

If you are a consultant, manager, meeting facilitator, team leader, community organizer, or simply someone who is involved in lots of group decisions, Consensus Through Conversation was written for you. Consensus Through Conversation is a portable, easy-to-read reference to help you facilitate and participate in consensus decision-making processes. It contains the basic principles and methods for making consensus work, whether in the corporate boardroom or in the community meeting hall. This book was developed as a companion to Consensus Cards, a tool I developed to assist groups in making consensus-based decisions. The book can be used on its own or in conjunction with this tool....Consensus can be a powerful and transformative tool. However, it is by no means a panacea that will transform your organization into a perfectly democratic or otherwise utopian world. Your job as a leader will be to decide when and where to use a consensus-based approach (see Guidelines in section entitled ''Consensus Defined, '' Chapter 1)

Complexes of physically interacting proteins constitute fundamental functional units that drive almost all biological processes within cells. A faithful reconstruction of the entire set of protein complexes (the "complexosome") is therefore important not only to understand the composition of complexes but also the higher level functional organization within cells. Advances over the last several years, particularly through the use of high-throughput proteomics techniques, have made it possible to map substantial fractions of protein interactions (the "interactomes") from model organisms including Arabidopsis thaliana (a flowering plant), Caenorhabditis elegans (a nematode), Drosophila melanogaster (fruit fly), and Saccharomyces cerevisiae (budding yeast). These interaction datasets have enabled systematic inquiry into the identification and study of protein complexes from organisms. Computational methods have played a significant role in this context, by contributing accurate, efficient, and exhaustive ways to analyze the enormous amounts of data. These methods have helped to compensate for some of the limitations in experimental datasets including the presence of biological and technical noise and the relative paucity of credible interactions. In this book, we systematically walk through computational methods devised to date (approximately between 2000 and 2016) for identifying protein complexes from the network of protein interactions (the protein-protein interaction (PPI) network). We present a detailed taxonomy of these methods, and comprehensively evaluate them for protein complex identification across a variety of scenarios including the absence of many true interactions and the presence of false-positive interactions (noise) in PPI networks. Based on this evaluation, we highlight challenges faced by the methods, for instance in identifying sparse, sub-, or small complexes and in discerning overlapping complexes, and reveal how a combination of strategies is necessary to accurately reconstruct the entire complexosome.

When electronic digital computers first appeared after World War II, they appeared as a revolutionary force. Business management, the world of work, administrative life, the nation state, and soon enough everyday life were expected to change dramatically with these machines’ use. Ever since, diverse prophecies of computing have continually emerged, through to the present day. As computing spread beyond the US and UK, such prophecies emerged from strikingly different economic, political, and cultural conditions. This volume explores how these expectations differed, assesses unexpected commonalities, and suggests ways to understand the divergences and convergences. This book examines thirteen countries, based on source material in ten different languages—the effort of an international team of scholars. In addition to analyses of debates, political changes, and popular speculations, we also show a wide range of pictorial representations of "the future with computers."

Synchronisation is an important process for different kinds of systems, such as biological, chemical, physical and social. Among the related synchronisation problems, consensus has received high attention because of the distributed properties shown by its models and the possibility they offer for controlling complex systems. When dealing with consensus processes in social networks, we known from empirical evidence that the formation of opinions is not free from being influenced by people around every actor, and more, it is well known that some of the actors may play a leading role and guide a social system to a final state different from the pure average consensus. A main paradigm while modelling interactions among actors in social networks is that every actor receives and transmits information from and to her nearest neighbours, thus implicitly assuming that the decisions of a given actor only are influenced by their directly connected peers, and not tking into account indirect influences coming from not directly connnected peers in the same social network, for example, the influence coming from the friend's friend of a friend. Our work studies consensus processes in the presence of influence coming from not only those directly connected actors, but from other ones in the same network. We call this influence peer pressure (PP). We propose a consensus model that takes into account direct and indirect PP modelled as a function of the social distance among actors. We apply this consensus model to different real social networks assuming three different decay laws for the strength of PP, and in the presence of leaders and without them. We choose those nodes acting as leaders according to different centrality criteria, as well as randomly, and compare thier performance for driving the system. Since it is natural that different leaders may diverge in their positions, we introduce a divergence parameter among the initial states of the leaders with respect to the avreage consensus of the system, to take the feature into account in our model. We then analyse the effects of PP on two different real cases of diffusion of innovation processes. We show that as the strength of indirect PP increases, the centrality criteria used to select the leaders has a decaying effect on the effectiveness of such leaders to better drive a consensus process, allowing random leaders to be as good as those with better centrality. Our work also shows that, despite divergence among leaders induces higher times for reaching consensus, this effect is reduced for stronger levels of PP present in the system. For the case of diffusion innovations our model reproduces the behaviour of the empirical data, and we demonstrate that certainlevels of PP are necessary to match the results coming from two different studies, supporting our hypothesis that indirect PP is an important factor to be taken into account when modelling opinion formations in social networks. Leaders emerging by global centrality criteria in networks with tightly connected groups can be counterproductive. This can be tackled by selecting node-leaders in a local basis. This effect is also reduced when indirect PP is allowed to be higher. This finding points to the fact that distance among nodes is an important characteristic for consenus processes. For the purpose of studying this structural feature, we propose a distance-sum heterogeneity index based on a fictional consensus process. We conjecture that an special type of graph, that we call complete split graph, is related with the maximization of the index, and based on this conjecture we study the relative distance-sum heterogeneity of random graphs and different real-world networks, which allows us to characterise them. We propose a spectral representation of the distance-sum heterogeneity index for networks that we call S-plots. We also study the relation between the time for consensus and the distance-sum heterogeneities in complex networks from different nature.

As the structure of contemporary communication networks grows more complex, practical networked distributed systems become prone to component failures. Fault-tolerant consensus in message-passing systems allows participants in the system to agree on a common value despite the malfunction or misbehavior of some components. It is a task of fundamental importance for distributed computing, due to its numerous applications. We summarize studies on the topological conditions that determine the feasibility of consensus, mainly focusing on directed networks and the case of restricted topology knowledge at each participant. Recently, significant efforts have been devoted to fully characterize the underlying communication networks in which variations of fault-tolerant consensus can be achieved. Although the deduction of analogous topological conditions for undirected networks of known topology had shortly followed the introduction of the problem, their extension to the directed network case has been proven a highly non-trivial task. Moreover, global knowledge restrictions, inherent in modern large-scale networks, require more elaborate arguments concerning the locality of distributed computations. In this work, we present the techniques and ideas used to resolve these issues. Recent studies indicate a number of parameters that affect the topological conditions under which consensus can be achieved, namely, the fault model, the degree of system synchrony (synchronous vs. asynchronous), the type of agreement (exact vs. approximate), the level of topology knowledge, and the algorithm class used (general vs. iterative). We outline the feasibility and impossibility results for various combinations of the above parameters, extensively illustrating the relation between network topology and consensus.

This book aims to explain how collective behavior is formed via local interactions under imperfect communication in complex networked systems. It also presents some new distributed protocols or algorithms for complex networked systems to comply with bandwidth limitation and tolerate communication delays. This book will be of particular interest to the readers due to the benefits: 1) it studies the effect of time delay and quantization on the collective behavior by non-smooth analytical technique and algebraic graph theory; 2) it introduces the event-based consensus method under delayed information transmission; In the meantime, it presents some novel approaches to handle the communication constraints in networked systems; 3) it gives some synchronization and control strategies for complex networked systems with limited communication abilities. Furthermore, it provides a consensus recovery approach for multi-agent systems with node failure. Also, it presents interesting results about bipartite consensus and fixed-time/finite-time bipartite consensus of networks with cooperative and antagonistic interactions.

Melanoma is considered to be one of the most aggressive forms of skin neoplasms. Despite aggressive researches towards finding treatments, no effective therapy exists to inhibit the metastatic spread of malignant melanoma. The 5-year survival rate of metastatic melanoma is still significantly low, and there has been an earnest need to develop more effective therapies with greater anti-melanoma activity. Through the accomplishment of over 100 distinguished and respected researchers from 19 different countries, this book covers a wide range of aspects from various standpoints and issues related to melanoma. These include the biology of melanoma, pigmentations, pathways, receptors and diagnosis, and the latest treatments and therapies to make potential new therapies. Not only will this be beneficial for readers, but it will also contribute to scientists making further breakthroughs in melanoma research.
