INTERDISCIPLINARITY OF SCIENTIFIC OBJECTIVES – While the scientific objectives of this project are heterogeneous, this consortium is relatively homogeneous regarding the background of participating scientists, mostly physicist of condensed matter or complex systems. In the last ten years, the research of some of the groups has approached other scientific fields, with the result that collaborations with groups in other institutions, with specialists in complementary experimental techniques or with different backgrounds has become mandatory. This is the reason that we have a number of external collaborators, which contribute their experience there where our own background becomes insufficient. In this same direction, we highlight the participation of two associated members, Bmat and Innaxis, with interest in the potential applicability of the results derived from this project. GISC-UC3M and UPM collaborate with the group of Jordi Bascompte (field ecology, theoretical biology and evolution) in the Estación Biológica de Doñana, CSIC; CAB maintains regular collaborations with researchers from that center (Ester Lázaro, viral dynamics; Carlos Briones, RNA world) and with the group of Esteban Domingo (evolution of RNA viruses) in the Centro de Biología Molecular “Severo Ochoa” (UAM-CSIC); GICS-UC3M collaborates with an economist hired by the group itself, as well as with Miguel Angel Zavala, from the Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (INIA). Other collaborators of this group are: Giorgio Cinacchi, University of Bristol, UK; Zhengdong Cheng, Texas A&M University, US; Szabolcs Varga, University of Pannonia, Veszprém, Hungary; István Szalai, University of Pannonia, Veszprém, Hungary; Luis Lafuente, Universidad de Sevilla; Andrew O. Parry, Imperial College London, UK; Rob Beardmore, Imperial College London, UK; and Michael E. Cates, University of Edinburgh, UK. The group URJC has been collaborating in the last years with the company Bmat in optimizing recommendation systems in sociale networks. It has also collaborated with members of Innaxis in characterizing spatially extended networks. Finally, thel group GISC-UCM maintains collaborations with: Chris van der Broeck, Universidad de Hasselt, Belgium; Frank Jülicher, Max Planck Institute for the Physics of Complex Systems, Dresden, Germany; Rodrigo Soto, Universidad de Chile, Chile; Victor A. Malyshev and J. Knoester, University of Groningen, Holland; Cord Müller, University of Bayreuth, Germany; Vittorio Bellani, University of Pavia, Italy; Rudolf Römer, Unirsity of Warwick, UK; Rudolf Hey, Paul Drude Institute, Germany; Pedro Orellana, Universidad Católica del Norte, Chile; Enrique Diez, Universidad de Salamanca, Spain; Ara Sedrakyan, Yerevan Institute of Physics, Armenia; Marcelo Lyra, Universidade Federal de Alagoas, Brasil; and Constantino Tsallis, Centro Brasileiro de Pesquisas Físicas, Brasil.
