COEVOLVE: A Joint Point Process Model for Information Diffusion and Network Co-evolution [article]

Mehrdad Farajtabar and Yichen Wang and Manuel Gomez Rodriguez and Shuang Li and Hongyuan Zha and Le Song
2016 arXiv   pre-print
We propose a temporal point process model, COEVOLVE, for such joint dynamics, allowing the intensity of one process to be modulated by that of the other.  ...  However, these two highly intertwined stochastic processes, information diffusion and network evolution, have been predominantly studied separately, ignoring their co-evolutionary dynamics.  ...  Generative Model of Information Diffusion and Network Evolution In this section, we use the above background on temporal point processes to formulate Coevolve, our probabilistic model for the joint dynamics  ...

Guns or Money? Defense Co-operation and Bilateral Lending as Coevolving Networks

Brandon J Kinne, Jonas B. Bunte
2018 British Journal of Political Science  
To empirically test these claims, the study develops a longitudinal model of multiplex network coevolution.  ...  For example, defense partners rely on loans to co-ordinate their foreign policies and better respond to security threats, and debtors rely on lending patterns to identify suitable defense partners.  ...  We model the coevolutionary dynamics of loan and DCA networks using a modified stochastic actor-oriented model (SAOM) of network evolution, 85 which has been fruitfully applied to other areas of international  ...

Coevolved Mutations Reveal Distinct Architectures for Two Core Proteins in the Bacterial Flagellar Motor

Alessandro Pandini, Jens Kleinjung, Shafqat Rasool, Shahid Khan, Anna Roujeinikova
2015 PLoS ONE  
Residue interactions, measured by their coevolution, were formalized as a network, guided by structural data. Our measurements reveal a common design with dedicated switch and motor modules.  ...  Atomic models based on the Salmonella entrovar C-ring electron microscopy reconstruction have implications for switching, but lack consensus on the relative locations of the FliG armadillo (ARM) domains  ...  Drs David Blair and Michael Sadowski commented on the manuscript. The study was started as a senior undergraduate thesis project of Anam Ejaz (LUMS School of Science and Engineering. Pakistan).  ...

Novel genomic approaches to study antagonistic coevolution between hosts and parasites

Hanna Märkle, Sona John, Amandine Cornille, Peter D. Fields, Aurélien Tellier
2021 Molecular Ecology  
We conclude by pointing out methodological and theoretical gaps to be filled to extract maximum information from full genome data and thereby to shed light on the molecular underpinnings of coevolution  ...  This review focuses on three recently developed approaches that leverage information from host and parasite full genome data simultaneously to pinpoint coevolving loci and draw inference on the coevolutionary  ...  It is desirable to use joint analysis of genome data from hosts and parasites to distinguish strict/diffuse coevolution from unilateral evolution ( in answering three sets of coevolutionary questions  ...

An Integrated Modeling Environment to Study the Co-evolution of Networks, Individual Behavior and Epidemics

Christopher Barrett, Keith Bisset, Jonathan Leidig, Achla Marathe, Madhav V. Marathe
2010 The AI Magazine  
Individual-based models of within-host disease progression and inter-host transmission are then used to model the contagion process.  ...  We discuss an interaction-based approach to study the coevolution between socio-technical networks, individual behaviors, and contagion processes on these networks.  ...  Acknowledgments We thank our external collaborators and members of the Network Dynamics and Simulation Science Laboratory (NDSSL); the work reported here is a joint effort of all the team members.  ...

Gender Equality – Legal Reality in Albania

Enejda Osmanaj
2014 European Journal of Social Sciences Education and Research  
The objective for gender equality policy is that women and men must have the same power to shape society and their own lives.  ...  Women's rights are an integral and indivisible part of fundamental human rights and a real, applicable, legal protection is needed.  ...  Each part in a co-evolutionary relationship exerts selective pressures on the other, thereby affecting each others' evolution. in a co-evolutionary model of innovation system, two sub dynamics are assumed  ...

Morphogenetic Robotics: A New Paradigm for Designing Self-Organizing, Self-Reconfigurable and Self-Adaptive Robots [chapter]

Yaochu Jin, Yan Meng
2012 Understanding Complex Systems  
We categorize these methodologies into three areas, namely, morphogenetic swarm robotic systems, morphogenetic modular robots and morphogenetic co-design of body and brain for robots.  ...  By morphogenetic robotics, we mean a class of methodologies for designing self-organizing, self-reconfigurable and self-adaptive robots inspired by biological morphogenesis.  ...  YJ is grateful to Edgar Körner and Bernhard Sendhoff for their support.  ...

Mobile Television: Challenges of Advanced Service Design

Johannes M. Bauer, Im Sook Ha, Dan Saugstrup
2007 Communications of the Association for Information Systems  
In this paper, we propose an integrative framework based on dynamic models of the evolution of industries. The main arguments are illustrated using the case of mobile TV.  ...  The new environment requires a significantly higher degree of coordination and integration between more participants in the value net and a consistent constellation of technology, policy and firm strategy  ...  A main difference to these earlier theories is that co-evolutionary models explicate the process of dynamic changes in more detail by building upon recent developments of generic evolutionary models.  ...

Co-evolution in Big History: A Transdisciplinary and Biomimetic Approach to the Sustainable Development Goals

Javier Collado-Ruano
2018 Social Evolution & History  
In conclusion, biomimicry finds in Big History a perfect theoretical model to understand how humanity must coevolve in harmony with nature.  ...  As a result of the discussion, those co-evolutionary operational principles of ecosystem cooperation must be bio-mimetically copied, emulated, and improved to reduce ecological footprint and to achieve  ...  So the co-evolutionary process has been used in a relatively restricted sense in the context of biological evolution.  ...
