This article examines conceptual and terminological inconsistencies in studies of job
quality, quality of employment, and quality of working life within English- and Russian- language academic
literature. Through a systematic review of publications, the study examines key concepts such as job
quality, quality of employment, decent work, and quality of working life, identifying their conceptual
distinctions, disciplinary specificities, and ...

We study the additive theory of arbitrary figures in linear spaces, that is, the theory of
addition extended to sets of vectors. Our main result is the following: if a linear space is infinite,
then the additive theory of figures admits interpreting second-order arithmetic and, therefore, it has
such or higher degree of undecidability. For countably infinite spaces, ...

A vertex subset of a graph is called a \textit{distance-$k$ independent set} if the distance between any two of its distinct vertices is at least $k + 1$. For all $n,k \geq 1$, we determine the minimum possible number of inclusion-wise maximal distance-$k$ independent sets among all $n$-vertex trees. It equals~$n$ if $n \leq k ...

This book presents a critical examination of how cultural forms, ranging from cinema and TV to literature, address class within the overarching context of a crisis conjuncture, specifically the period following the 2008 financial crash. It demonstrates how culture serves as a crucial site for capturing the contemporary "structure of feeling", publicly mediating the period's ...

We introduce an explicit class of tempered Laurent polynomials in the sense of Villegas and Doran--Kerr in n⩽4 variables including all Landau--Ginzburg models for smooth Fano threefolds with very ample anticanonical class. We check that it contains Landau--Ginzburg models for various Fano fourfolds which are complete intersections in smooth toric varieties and Grassmannians of planes, ...

Macroeconomic instability in the period of 2020–2024 has revived discussions about its impact on economic convergence processes and methods for assessing the convergence of developing and developed countries. This paper presents a systematic analysis of modern econometric approaches and existing limitations in testing the convergence hypothesis. The methodological framework is based on classical Solow economic ...

The catch-up effect has always been a pressing issue in economics: are developing countries truly catching up with technologically advanced countries, and is the economic gap between rich and poor countries narrowing over the long term? This article aims to test the hypothesis of economic convergence across countries, a key research issue in the field ...

Comprehensive data on natural hazards and their consequences are crucial for effective for risk assessment, adaptation planning, and emergency response. However, many countries face challenges with fragmented, inconsistent, and inaccessible data, particularly regarding local-scale events. To address this data gap in Russia, we developed an end-to-end processing pipeline that scrapes news from various online sources, ...

We perform a Monte Carlo analysis of the Ising model on many three-dimensional lattices. By means of finite-size scaling we obtain the critical points and determine the scaling dimensions. As expected, the critical exponents agree with the three-dimensional Ising universality class for all models. The irrelevant field, as revealed by the correction-to-scaling amplitudes, appears to ...

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

Label prediction in neural networks (NNs) has O(n) complexity proportional to the number of classes. This holds true for classification using fully connected layers and cosine similarity with some set of class prototypes. In this paper we show that if NN latent space (LS) geometry is known and possesses specific properties, label prediction complexity can ...

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 ...

This paper attempts to model the evolutionary theory of modernization and democratization. The model reflects the key provisions of R. Inglehart and C. Welzel's theory and provides a microfoundation for the adaptation of subjective values to the objective importances of the survival factors and the structure of the labour markets from the perspective of evolutionary ...

Context and Relevance. One of the most widely used instruments for assessing secondary traumatic stress (STS) is the Secondary Traumatic Stress Scale (STSS). This 17-item questionnaire has demonstrated strong reliability and construct validity across international studies, with consistently high internal consistency and robust psychometric performance. The present study evaluates the psychometric properties of the Russian-language ...

Community detection in complex networks is a fundamental problem, open to new approaches in various scientific settings. We introduce a novel community detection method, based on Ricci flow on graphs. Our technique iteratively updates edge weights (their metric lengths) according to their (combinatorial) Foster version of Ricci curvature computed from effective resistance distance between the ...

Transport coding reduces message delay in packet-switched networks by introducing controlled redundancy at the transport layer: original packets are encoded into coded packets, and the message is reconstructed after the first successful deliveries, effectively shifting latency from the maximum packet delay to the -th order statistic. We present a concise, reproducible discrete-event implementation of transport coding in OMNeT++, including ...

This study investigates the relationship between individual religiosity and attitudes towards immigrants of different religious backgrounds in Europe. Using data from the 7th wave of the European Social Survey (2014-2015), we examine the influence of individual denomination and subjective religiosity level on hostility towards Muslim immigrants and the importance of immigrants’ Christian background. Our analysis, ...

We argue that a classification-based approach to measuring cultural differences across countries or subnational regions is a promising complement, and sometimes an alternative, to the widely used dimensional method in cross-cultural research. The latter summarises cultural variation using continuous dimensions, for example, Hofstede’s famous individualism-collectivism dimension. However, this approach relies on strong parametric assumptions, which are ...

Non-probability web surveys offer several advantages over face-to-face (F2F) interviews—they are cheaper, faster, more accessible, and reduce interviewer effects and desirability bias. As such, they are increasingly popular in both academic and commercial research. However, they often yield demographically biased samples, raising concerns about the accuracy of the resulting public opinion estimates. Most studies on ...

Hessian-based lightweight neural network for brain vessel segmentation on a minimal training dataset
Меньшиков И. А., Бернадотт А. К., Elvimov N. S., / Series arXie "Statistical mechanics". 2025.
Accurate segmentation of blood vessels in brain magnetic resonance angiography (MRA) is essential for successful surgical procedures, such as aneurysm repair or bypass surgery. Currently, annotation is primarily performed through manual segmentation or classical methods, such as the Frangi filter, which often lack sufficient accuracy. Neural networks have emerged as powerful tools for medical image ...

We investigate the boundary separating regular and chaotic dynamics in the generalized Chirikov map, an extension of the standard map with phase-shifted secondary kicks. Lyapunov maps were computed across the parameter space (K,K(α, τ)) and used to train a convolutional neural network (ResNet18) for binary classification of dynamical regimes. The model reproduces the known critical ...

Research of the impact of kin alloparenting on reproduction mainly focuses on mother’s parents and parents-in-law. The impact on fertility of extended families and the alloparental help with childcare they can provide has received much less attention. Moreover, there is an important lacuna in the existing studies of this problem, as it is mostly approached ...
