Equivalence of Network Structures in Networks of Random Variables with Known and Unknown Shift Parameter
Journal of Mathematical Sciences. 2020. Vol. 248. No. 1. P. 129–137.
It is proved that sign network with elliptical distribution with known shift parameter is equivalent
to sign network with elliptical distribution with unknown shift parameter estimated as sample mean.
This result is proved for the case of independent identically distributed observation and for the case
of sample from matrix elliptically contoured distribution with any dependence between observations.

This paper investigates the problem of statistical inference for a mixture distribution consisting of a discrete and a continuous component, with a particular focus on the class of rational-infinitely divisible distributions. We consider non-parametric estimation of both components of the mixture as well as the quasi-L{é}vy measure, assuming that the mixture belongs to the class ...

This article examines series of families of two-dimensional circulant networks with rectangular
L -shapes, optimal in diameter, as network-on-chip topologies with a minimal number of crossings
between the links and a bounded length of the maximum link that does not depend on the network
size. New network-on-chip routing algorithms, which use the coordinates of three adjacent zeros in
the ...

We investigate the spatial overlap of successive spin configurations in Markov chain Monte Carlo simulations using the local Metropolis algorithm and the Swendsen-Wang and Wolff cluster algorithms. We examine the dynamics of these algorithms for models in different universality classes: Ising model, Potts model with three components, and four-state Potts model. The overlap of two ...

We study a model problem on the filtration of a conducting fluid through a
porous layer. A porous medium is presented as an assemblage of identical spherical
cells. Each cell consists of a porous core and liquid shell. We derive apriori estimates
for flow characteristics which show the specific behavior of the fluid. Our estimates
are validated numerically. ...

In the present paper we consider an Ω-stable 3-diffeomorphism with a solid or thickened surfaced non-trivial basic set. Such basic sets include, for instance, all one-dimensional expanding attractors and those two-dimensional basic sets that are not expanding. We prove that the chain recurrent set of every such a diffeomorphism necessarily contains at least two non-trivial ...

Пусть симплекс с целочисленными вершинами - содержащий ровно одну целочисленную точку, отличную от своих вершин. В работе доказывается, что если точка находится во внутренности симплекса или в относительной внутренности некоторой гиперграни симплекса, то объем симплекса ограничен величиной, зависящей только от размерности, в противном случае объем симплекса может быть сколь угодно большим. Этот результат применяется для вывода асимптотической формулы для среднего числа вершин полиэдров ...

We explore the fundamental principles underlying the architecture of the human brain’s structural connectome through the lens of spectral analysis of Laplacian and adjacency matrices. Building on the idea that the brain balances efficient information processing with minimizing wiring costs, our goal is to understand how the metric properties of the connectome relate to the ...

The paper introduces a new approach to modeling Internet shutdown during the process of protest mobilization. The central point of the approach is the sequential use of two networks, with different topologies built upon the same set of individuals. Some endogenously set proportion of connections is shared by both networks. A model of protest dynamics ...

The assumption that cultures are clearly defined, essentially self-contained entities has
been subjected to serious doubt in modern archaeology which needs to be reflected also
in Sarmatian studies. Such concepts as ‘Sarmatians’, ‘Sarmatian period’ and ‘Sarmatian
archaeological culture(s)’ are widely used in archaeological literature. However, the
monuments of the different macro-regions that are usually connected in scholarship with
the various ...

This paper considers a network game as follows. In each node of a network, economy
is described by the simple two-period Romer’s model of endogenous growth with production
and knowledge externalities. The sum of knowledge levels in the neighbor nodes causes an
externality in the production of each network node. The concept of node type is introduced
