The Izborsky Club positions itself as a "synthesis of Russian statists <...> from socialists and Soviet pa-triots to monarchists and Orthodox conservatives" and aims to unite representatives from diverse statist nationalist movements. The internal heterogeneity of Russian nationalism presents a challenge to the Izborsky Club's goal of developing a "new tradition", which involves constructing a ...

На основе анализа более двух миллионов сообщений в социальных сетях, практики патриотического активизма в социальных сетях, а также данных интервью с представителями «служащих» профессий, выявлены факторы развития деятельностной компоненты патриотической идентичности. Сделаны выводы о ключевых мотивациях, роли личностных факторов и социализации в формировании социального капитала, а также о связи служения со значимыми ценностями – семьей, ...

AI errors pose a significant challenge, hindering real-world applications. This work introduces a novel approach to cope with AI errors using weakly supervised error correctors that guarantee a specific level of error reduction. Our correctors have low computational cost and can be used to decide whether to abstain from making an unsafe classification. We provide ...

High-dimensional tabular data are common in biomedical and clinical research, yet conventional machine learning methods often struggle in such settings due to data scarcity, feature redundancy, and limited generalization. In this study, we systematically evaluate Synolitic Graph Neural Networks (SGNNs), a framework that transforms high-dimensional samples into sample-specific graphs by training ensembles of low-dimensional pairwise ...

This study presents on-the-fly identification and multi-step prediction of nonlinear systems with delayed inputs using a dynamic neural network combined with a smooth projection onto ellipsoids. The projection enforces parameter constraints that guarantee stability, while a Lyapunov–Krasovskii analysis yields computable ultimate error bounds. Riccati-type matrix inequalities are derived, providing an efficient vectorization–projection–devectorization implementation suitable for ...

The approximation of tensors in a low-para metric format is a crucial component in many mathematical modelling and data analysis tasks. Among the widely used low-parametric representations, the canonical polyadic (CP) decomposition is known to be very efficient. Nowadays, most algorithms for CP approximation aim to construct the approximation in the Frobenius norm; however, some ...

Political polarization is the phenomenon inseparably linked to Donald Trump's political activities since 2015. According to some researchers that polarization was the reason for Trump's victory in the elections. Others argue that polarization has grown because of Trump, and that the US population was much more united before his emergence on the political scene. In ...

Amidst the overarching imperative for a common foreign policy within the European Union, the long-term challenge to its implementation regarding the People’s Republic of China is the level of intra-Union unity. Special attention in this context is drawn to the case of Hungary, which not only contests the fundamental parameters of the EU foreign policy but also actively develops multifaceted relations with ...

A B-facet is a lattice -dimensional polytope in the positive octant with a positive normal covector, such that every -dimensional simplex with vertices in it is a B-simplex (i.e., a pyramid of height one with base on a coordinate hyperplane). B-facets were introduced in [2] in the context of the monodromy conjecture. In this paper, we complete the ...

Понимание российского внешнеполитического поведения вновь обретает осо-бую значимость не только в рамках конфликта на Украине и взаимоотношений со странами мирового большинства и меньшинства, но и в контексте изменяющегося мироустройства. Прежняя глобалистская модель стремительно сходит с авансце-ны международных отношений, возвращая, по сути, мир к структурным базовым настройкам соперничества между несколькими крупными державами. Россия яв-ляется одной из ...

The Vickrey-Clarke-Groves (VCG) mechanism is one of the most compelling constructs in mechanism design, but the presence of complementary goods creates the possibility of non-core and even zero-revenue outcomes. In this article, we show that joint feasibility constraints on allocations offer a second pathway to ill-behaved outcomes in the VCG mechanism, even when all bidders ...

We provide examples of smooth three-dimensional Fano complete intersections of degree 2, 4, 6, and 8 that have absolute coregularity 0. Considering the main theorem of Avilov, Loginov, and Przyjalkowski (CNTP 18:506–577, 2024) on the remaining 101 families of smooth Fano threefolds, our result implies that each family of smooth Fano threefolds has an element of absolute ...

Redistricting is an important tool of political struggle, distinguished
by several features that set it apart from other methods of creating a non-competitive electoral advantage: secrecy and non-provocativeness. These characteristics have led to significant scholarly attention, primarily focused on the
political consequences of redistricting. However, the administrative and legal
aspects of redistricting remain less studied, which may limit ...

We show that bifurcations of four-dimensional symplectic diffeomorphisms with a quadratic homoclinic tangency to a saddle periodic orbit with real multipliers produce 2-elliptic periodic orbits if the tangency is not partially hyperbolic. We show that a normal form for the rescaled first-return maps near such tangency is given by a four-dimensional symplectic H´enonlike map and study bifurcations of the ...

The book contains new models of bibliometric analysis based on centrality measures in network analysis, pattern analysis and stability analysis. A distinctive feature of these centrality measures is that they account for the parameters of vertices and group influence of vertices to a vertex. This reveals specific groups of publications, authors, terms, journals and affiliations ...

We develop a machine-learning approach to reproduce the behavior of two versions of the van der Pol oscillator exhibiting a subcritical Andronov–Hopf bifurcation, with or without a codimension-2 Bautin point. We construct a neural-network model that functions as a recur rent map and train it on short segments of oscillator trajectories. The results show that, ...

This paper proposes Covariate-Balanced Weighted Stacked Difference-in-Differences (CBWSDID), a design-based extension of weighted stacked DID for settings in which untreated trends may be conditionally rather than unconditionally parallel. The estimator separates within-subexperiment design adjustment from across-subexperiment aggregation: matching or weighting improves treated-control comparability within each stacked subexperiment, while the corrective stacked weights of Wing et ...

This article is devoted to the phenomenon of intrinsic motivation, to understand which two models are proposed. We study how positive/negative intrinsic motivation to work (experienced utility) affects worker's individual labour supply (model I) and the amount of effort they exert (model II). In model I, we use intrinsic motivation to explain the positive/negative slope ...

In this paper, we develop a formal mathematical model aimed to explain the Dunning-Kruger effect that beginners systematically overestimate their own competence in various fields of knowledge and activity. We argue that the Dunning-Kruger effect arises from the emotional nature of confidence combined with unknown unknowns that it simply can not take into account due ...
