Opinion Dynamics in an Open Community
Timoteo Carletti, Duccio Fanelli, Alessio Guarino +2
We here discuss the process of opinion formation in an open community where agents are made to interact and consequently update their beliefs. New actors (birth) are assumed to rep…
Understanding the nucleation mechanisms of Carbon Nanotubes in catalytic Chemical Vapor Deposition
Hakim Amara, Christophe Bichara, François Ducastelle
The nucleation of carbon caps on small nickel clusters is studied using a tight binding model coupled to grand canonical Monte Carlo simulations. It takes place in a well defined c…
Titan's rotation: A 3-dimensional theory
B. Noyelles, A. Lemaitre, A. Vienne
We study the forced rotation of Titan seen as a rigid body at the equilibrium Cassini state, involving the spin-orbit synchronization. We used both the analytical and the numerical…
Bounded modes to the rescue of optical transmission
Michael Sarrazin, Jean Pol Vigneron
This paper presents a brief survey of the evolution of knowledge about diffraction gratings. After recalling some basic facts, historically and physically, we introduce the concept…
Optical structure and function of the white filamentary hair covering the edelweiss bracts
Jean Pol Vigneron, Marie Rassart, Zofia Vertesy +5
The optical properties of the inflorescence of the high-altitude ''Leontopodium nivale'' subsp. ''alpinum'' (edelweiss) is investigated, in relation with its submicrometer structur…
Centrality measures and thermodynamic formalism for complex networks
Jean-Charles Delvenne, Anne-Sophie Libert
In the study of small and large networks it is customary to perform a simple random walk, where the random walker jumps from one node to one of its neighbours with uniform probabil…
