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 ...

Large language models have recently demonstrated promising capabilities in mathematical reasoning; however, their performance on tasks requiring strict symbolic manipulation, such as solving differential equations, remains limited, especially for compact models. In this work, we investigate whether activation steering combined with reinforcement learning can improve the quality of solutions generated by pretrained language models without ...

The article presents the results of a comparative analysis of fertility indicators for Russian female cohorts born in the 1930s–1980s, obtained using two independent methods: (a) estimates based on the results of national surveys of women collecting information on the number of children ever born; and (b) estimates derived from specially constructed cohort age-and parity-specific ...

Republican ideology in Mexico in the first third of the 19thcentury is an important and insufficiently studied as-pect of the formation of national identity and political culture in the postcolonial period. The present study is based on the methodology of the Cambridge School of Intellectual History and interprets republicanism as a dynamic dis-cursive practice that ...

This paper studies the technical efficiency of Russian retail companies in 2019 to 2023 using stochastic frontier analysis (SFA) with the Battese and Coelli (1995) model. A translogarithmic production function is employed for estimations. The dependent variable is company revenue, and the production factors are the average number of employees, fixed assets, and assets less ...

During a survey on the territory of the Eklizi-Burun cult complex, a repeatedly densely
folded fragment of a gilded silver sheet was discovered. When unfolded during the restoration
process, it turned out to be a fragment of an art object depicting the mask of Medusa Gorgon.
The size and shape of the object suggest its purpose as a ...

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

В работе представлен анализ динамики и факторов младенческой смертности в регионах России в 1927-2022 гг., проведенный на данных Демоскоп Weeklyи Российской базы данных по рождаемости и смертности. Несмотря на значимость регионального фактора в младенческой смертности, особенно на ранних этапах наблюдаемого временного отрезка, эффект периода, как правило, оказывался важнее. Так,значительные успехи в снижении младенческой смертности в ...

This study examines the individual factors of artificial intelligence (AI) implementation by small and medium-sized enterprise (SME) owners, based on a survey of 499 respondents in Russia. Drawing on Innovation Diffusion Theory, the Technology Acceptance Model (TAM), and stakeholder-oriented sustainability approach, the analysis shows that SME owners who already use AI for private purposes are ...

Gift giving is a widespread social practice with a long history, which is an important part of social relations. However, the gift giving of books may be difficult to describe with the help of classical gift exchange theories. The aim of the present study is to determine the palette of meanings exchanged between giver and ...

This article examines changes in the quantum and structural characteristics of period and cohort fertility in Russia in the context of pro-natalist demographic policy pursued since 2006. The study assesses the significance of recent decades’ shifts for total fertility, the age profile of mothers, and their distribution by number of children born. The analysis draws ...

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 ...

Within narrowly defined industries, the most productive firms produce far more than the least productive from the same inputs, and this dispersion widens in downturns. We build a tractable representative-agent model in which financial frictions—adverse selection and moral hazard—make firms sort endogenously into lenders, strategic defaulters, and producers. As credit conditions vary, the resulting misallocation ...

В аналитической записке обсуждается долгосрочно устойчивый уровень цены на российскую нефть. Это тот уровень, к которому цена нефти, вероятнее всего, будет тяготеть в долгосрочной перспективе. Потребность в его определении возникает по нескольким причинам. Во-первых, цена на нефть остается одним из ключевых экономических показателей российской экономики, определяющих экспорт, обменный курс рубля, прибыль, доходы и расходы бюджета, ...

The paper proposes a graphical model of a small open economy. The dynamics of the graphical model is then illustrated using impulse responses from the corresponding formal semi-structural model (QPM model). The authors have several goals in preparing this description of the graphical macroeconomic model. The first goal of the paper is to present an adapted ...

A noncommutative projective variety is defined, following Artin and Zhang, by a graded coherent algebra 𝐴. The category of coherent sheaves is then the quotient qgr(𝐴) of the category of finitely presented graded modules by the subcategory of torsion modules. We consider the categorical and polynomial entropies of the Serre twist, that is, of the ...

If a symmetric multilinear algebra is weakly nil, then it is Engel. This result may be regarded as an infinite-dimensional analogue of the well-known Jacobian theorem, which states that if a polynomial mapping has a polynomial inverse, then its Jacobian matrix is invertible. This refines a theorem of Gerstenhaber and partially answers a question posed ...

This work develops a tractable model of price competition in fragmented markets where consumers consider both local and distant varieties, with cross-regional purchases subject to stochastic costs. Global competition and full localization emerge as polar cases; hybrid competition is not merely intermediate and exhibits distinctive features such as an endogenous price ceiling and non-monotonic entry ...

Elaborating on Welzel et al.'s "Cool Water Theory," our study zooms into the more limited (albeit still varied) framework conditions of Russia's huge territory. Within Russia's confines, we examine how the combination of moderately cool seasons with steady rain (i.e., Cool Water) affects sub-national areas' contemporary societal progress in two modernization indicators: material prosperity in ...
