    Holovko, M.F.; Shmotolokha, V.I. (Condensed Matter Physics, 2018)
    The scaled particle theory (SPT) approximation is applied for the study of the influence of a porous medium on the isotropic-nematic transition in a hard spherocylinder fluid. Two new approaches are developed in order ...
  • Scale of radionuclide emission at the Chornobyl Nuclear Power Plant in 1986 (The analysis of estimations) 
    Checherov, K.P.; Kumshaev, S.B.; Tokarchuk, M.V. (Condensed Matter Physics, 2000)
    How much fuel remained inside the Chornobyl Unit 4 after the accident? What is the scale of radionuclide emission in the environment? Till now these questions excite the scientific community of the world. The critical analysis ...
  • Scaling functions and amplitude ratios for the Potts model on an uncorrelated scale-free network 
    Krasnytska, M. (Condensed Matter Physics, 2014)
    We study the critical behaviour of the q-state Potts model on an uncorrelated scale-free network having a power-law node degree distribution with a decay exponent λ. Previous data show that the phase diagram of the model ...
  • Scaling in charged fluids: beyond simple ions 
    Blum, L. (Condensed Matter Physics, 2001)
    The analytical solution of the Mean Spherical Approximation for a quite general class of interactions is always a function of a reduced set of scaling matrices Γχ. We extend this result to systems with multipolar ...
  • Scaling in public transport networks 
    von Ferber, C.; Holovatch, Yu.; Palchykov, V. (Condensed Matter Physics, 2005)
    We analyse the statistical properties of public transport networks. These networks are defined by a set of public transport routes (bus lines) and the stations serviced by these. For larger networks these appear to possess ...

    Fricke, N.; Zierenberg, J.; Marenz, M.; Spitzner, F.P.; Blavatska, V.; Janke, W. (Condensed Matter Physics, 2017)
    We study the scaling laws of diffusion in two-dimensional media with long-range correlated disorder through exact enumeration of random walks. The disordered medium is modelled by percolation clusters with correlations ...
