We introduce two new measures of network robustness and apply them to four different strategies. The measures are independent from the number of nodes in the network and have the strong potential to cover a large portfolio of applications. Using the Monte-Carlo methods, we demonstrate how to...

В статье рассматривается ряд малоисследованных аспектов, связанных с изучением проблем развития малого и среднего бизнеса как фактора конкурентоспособности...

A model for diffusion and phase separation which takes into account exponential relaxation of the solute diffusion flux and its fluctuations is developed. The model describes a system undergoing phase separation governed by a partial differential equation of hyperbolic type. The analysis is done...

Multidensity integral equation theory for a model of an associating fluid forming freely jointed fused hard-sphere chain, is presented. Our approach is based on the Wertheim's polymer Percus-Yevick (PPY) theory supplemented by the ideal chain approximation and can be regarded as an extension of...

The scattering and critical properties of weakly charged ramified polymeric systems for any arbitrary topology are investigated by using the random phase approximation. The interaction matrix is modeled as the sum of the short-range excluded volume matrix and the long-range Debye–Hûckel...

Our earlier work applying the self-consistent Ornstein-Zernike approach (SCOZA) to the D-vector model is extended to a more general class of continuous-spin models for which the constraint of a single-spin magnitude is relaxed.

We study the time-dependent structure factor of the one-dimensional Glauber model upon instantaneous cooling. Results obtained earlier by Reiss, Mazenko and Widom, and Bray, are linked together. Next, finite-size scaling in the limit of zero temperature, long times, small wave vectors, and large...

By means of extensive numerical simulations we have studied the time evolution and the scaling properties of the structure factor S(q,t) of diffusion-limited (DLCA) and reaction-limited (RLCA) colloid aggregation in three dimensions. We found that in DLCA S(q, t) scales in a similar way as in...
