An ocean of diffusible information

Trends in Genetics
In the ocean, free-living bacteria exist in a dilute world where direct physical interactions between cells are relatively rare. How then do they exchange genetic information via horizontal gene transfer (HGT)? Lücking et al. have explored the world of marine 'protected extracellular DNA' (peDNA), and find that extracellular vesicles (EVs) are likely ...

Principle of information diffusion

Fuzzy Sets and Systems, 1997
Abstract In this paper, we discuss the characteristic of incomplete data, and suggest the principle of information diffusion to deal optimally with them to recognize the concerning relationships. The basic function of the principle is to expand a crisp observation so as to stuff the gap caused by lacking data.

Diffusion of geographic information innovations

International journal of geographical information systems, 1991
Abstract Appropriate diffusion of geographic information technologies is hampered by lack of systematic research on factors and processes affecting diffusion, utilization and impact assessment of the technologies and by a variety of conceptual and methodological problems. Diffusion of innovation principles developed in other fields, in combination with

Information and Attitude Diffusion in Networks

2012
The availability of diverse information does not guarantee that a person's views will be equally diverse. Research has consistently shown that attitudinal positions on an issue will lead to selective reception and dissemination of information, which in turn have reciprocal effects on those attitudes.

Diffusion and information

International Journal of Heat and Mass Transfer, 1983
Theorie de l'information appliquee au cas de la diffusion. On fait des experiences pour mesurer les diffusivites et la connaissance de celles-ci et des lois de diffusion aboutissent aux variations dependant du temps dans les distributions ...

Information diffusion through blogspace

Proceedings of the 13th international conference on World Wide Web, 2004
We study the dynamics of information propagation in environments of low-overhead personal publishing, using a large collection of WebLogs over time as our example domain. We characterize and model this collection at two levels. First, we present a macroscopic characterization of topic propagation through our corpus, formalizing the notion of long ...

Modelling Spatial Information Diffusion

2019
This paper develops an open source toolkit SocialNetworkSimulator to model social networks based on a group of tweets with the keyword of ‘Charlotesville’, a topic vividly discussed over Twitter on the movement ‘Unite the Right rally’ occurred in Charlottesville, Virginia from August 11 to August 12, 2017.

Critical Information Diffusion Systems

2015
Today, individuals, companies, organizations and national agencies are increasingly interconnected, forming complex and decentralized information systems. In some of these systems, the very fact of exchanging information can constitute a safety critical concern in itself. Take for instance the prevention of natural disasters.

Optimal Unconditional Information Diffusion

2001
We present an algorithm for propagating updates with information theoretic security that propagates an update in time logarithmic in the number of replicas and linear in the number of corrupt replicas. We prove a matching lower bound for this problem.
