BACKGROUND Cytogenetically detectable aberrations of the Y chromosome, such as isodicentrics, rings or translocations are sometimes associated with male non-obstructive infertility. This report...

In (Deffuant et al., 2002), we proposed a simple model of opinion dynamics, which we used to simulate the influence of extremists in a population. Simulations were run without any specific...

Individual-based model to enrich an aggregate model (2003)
Duboz, R., Amblard, F., Ramat, E., Deffuant, G., Preux, P.
We propose to use individual-based models as virtual laboratories to identify parameters of aggregate models. We illustrate this approach with a simple example: the diffusion of particles animated by...

Which ties to choose? A survey of social networks models for agent-based social simulations (2002)
We focus on the social network component of social simulation models. As confronted to the choice of an interaction structure model, "Which ties to choose?" is a relevant question for the social...

How can extremism prevail? A study based on the relative agreement model (2002)

Interacting Agents with Continuous Uncertain Opinions (2001)
Deffuant, G., Amblard, F., Faure, T., Weisbuch, G.
We present several possible extensions of a model of opinion dynamics in which each agent adjusts a continuous opinion as a result of an interaction with a randomly chosen other agent whenever the...

Molecular analysis of antigen-independent adhesion forces between T and B lymphocytes.
