Universal scaling behavior at interfaces
Rough surfaces and interfaces are ubiquitous in nature and from technological point of view the control of their roughness is becoming critical for applications in fields such as microelectronics, image formation, surface coating or thin film growth S. Chow, Mesoscopic Physics of Complex Materials Texts in Contemporary Physiscs, Springe 2000). During the last years there has been an interest in the description of of the self-affine kinetic roughening of surfaces, the microstructure (see: "A. Yanguas-Gil et al. ,Phys. Rev. Lett, 96 (2006) 236101).
Related topicis are the depinning transition of elastic systems in disordered media
(A.B. Colton et al., Phys. Rev. Lett 97 (2006) 057001) and the wetting transition transitions. In application to parallel and distributed computations, the important consequence of the derived scaling is the existence of the upper bound for the desynchronization in a conservative update algorithm for parallel discrete-event simulations (A. Kolakowska et al. Phys. Rev. E 70 051602 (2004)).
Understanding the fundametal laws driving the tumor development is one of the biggest challenges of contemporary science. Internal dynamics of a tumor reveals itself in a number of phenomena, one of the most obvious ones being the growth
