The Vicsek model describes the evolution of a system composed by different agents moving in the plane. Each agent has a constant speed and updates its heading using a local rule depending on the headings of its “neighbors”. Although the original model by Vicsek is non-linear, most of the convergence results obtained so far deal with linearized versions. In this paper, we introduce a new linear ...

In this response to the comment by Champagne-Lavau and Moreau (2013), we acknowledge the importance of ecological mentalizing assessments that allow direct interactions between the agent and the person to whom mental states are attributed. Furthermore, we clarify that our model, the 8 sources of information framework (8-SIF; Achim, Guitton, Jackson, Boutin, & Monetta, 2013), aims to document th...

synthetic envelopes have been found to be highly effective filters for numerous applications and are currently replacing gravel envelopes. the growth of petrochemical and textile industries in iran offers the possibility of manufacturing these products domestically. the objective of this study was to assess the mineral clogging potential of two non-woven synthetic envelopes (pre-wrapped loose m...
