Rendiconti del Circolo Matematico di Palermo. 2023. Vol. 2. No. 72. P. 1797–1821.
We classify nonrational Fano threefolds X with terminal Gorenstein singularities such that $\mathrm{\rk}\, \mathrm{\Pic}(X)=1$, (−KX)3≥8, and $\mathrm{\rk}\, \mathrm{\Cl}(X)\le 2$.

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. ...

This book presents established and new research on the close connections between graph games and systems of logic, particularly existing and newly designed modal logics. The volume utilizes two graph games – the sabotage game and the hide-and-seek game – to demonstrate the natural interplay between designing new graph games and exploring new kinds of ...

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 ...

n this paper, we focus on the generalization of the Hurst empirical law and suggest a set of reduced parameters for quantitative description of long-time series. These series are usually considered as a specific response of a complex system (economic, geophysical, electromagnetic and other systems), where successive fixations of external factors become impossible. We consider ...

In this paper, we conducted a study of the prevalence of cheating among university students and analyzed the factors contributing to this phenomenon. Cheating is a form of opportunism, when an individual chooses a strategy to achieve success through deception, manipulation, or forgery. The research was carried out on the basis of a survey created ...

We introduce and study the notion of G-coregularity of algebraic varieties endowed with an action of a finite group G. We compute the G-coregularity of smooth del Pezzo surfaces of degree at least 6, and give a characterization of groups that can act on conic bundles with G-coregularity 0. We describe the relations between the notions of G-coregularity, G-log ...

Emerging Adults’ Autonomy in Romantic Narrative Identities: Choices Between Emotions and Rationality
Victoria G. Yerofeyeva, Ekaterina M. Tsyganova, Bochaver A. A., Trends in Psychology 2025
This study examines how emerging adults define autonomy through their roman
tic relationship choices. Emerging adulthood provides a lot of opportunities to try
different things, but the diversity of alternatives makes it difficult to choose. Under
these conditions, autonomy becomes a necessary personal characteristic. We set
out to examine how young people construct romantic narratives identities based
on the characteristics ...

The paper presented to the reader’s attention pursues two goals. The first is a substantiation of the productivity of the concept “epistemic culture” (hereinafter – EC) as a tool of historico-philosophical intercultural research by the example of its application to the interpretation of the meanings of Indian logico-epistemological texts. The second is a demonstration of ...

Michael Friedman made an attempt to combine Kantian transcendental philosophy and Kuhn's historiographical model in a view of changes in science. His idea of a rational revision of scientific principles contrasts with Kuhn's idea of the existence of universal sets of values that ensure scientific progress. Friedman appeals to philosophical developments of the metatheoretical level ...

We show that the affine cones over any Fano–Mukai fourfold of genus 10 are flexible in the sense of [1]. In particular, the automorphism group of such a cone acts highly transitively outside the vertex. Furthermore, any Fano–Mukai fourfold of genus 10, with one exception, admits a covering by open charts isomorphic to ...
