This study explores the relationship between subjective well-being (SWB) and entrepreneurial intention (EI) among university students in Russia, where entrepreneurial engagement remains relatively low. It emphasizes the role of internal psychological drivers, such as SWB, willingness to take risks and entrepreneurial self-efficacy, rather than focusing solely on external factors. Drawing on the Theory of Planned ...

In the circular restricted three-body problem, families of periodic and quasi-periodic orbits exist in the vicinity of the libration points and are of significant interest for practical applications. This work presents a neural network-based algorithm for orbit construction and station-keeping, applicable to both periodic and quasi-periodic orbits near collinear libration points. The method employs a ...

Increasing female representation in technical majors, traditionally associated with high earnings, is recognised as a mechanism for promoting gender equality in the labour market. However, if women quit STEM soon after graduation, increasing their proportion in relevant disciplines will not help reduce the gender wage gap. This paper provides new evidence of the ‘leaky pipeline’ ...

В данном исследовании рассматривается связь между интеллектуальным капиталом компаний и их интернационализацией в условиях внешних шоков. В отличие от предыдущих работ, как правило, рассматривающих взаимосвязь интеллектуального капитала и интернационализации в стабильной экономике, в исследовании развиваются предположения о неоднородном влиянии шоков на компоненты интеллектуального капитала и, соответственно, различном модерационном эффекте шоков на трансформацию интеллектуального капитала в экспортную ...

We provide an infinite series of commutative finite-dimensional Gorenstein local algebras A_n for n ≥ 2. We give an elementary proof that the maximal ideal of every algebra A_n possesses a one-dimensional subspace that is different from the socle and invariant under the automorphism group of A_n. The latter implies that the algebras A_n fail ...

The paper offers a new perspective on the limit of government debt. It surveys the broad historical picture of the dynamics and character of government debt in the leading economies: the ratios of debt and debt service to GDP have risen to levels close to their half-century highs. In the regime that has taken shape ...

An inverse problem of reconstructing the turbulent exchange tensor from large archives of observed wind profiles within the Åkerblom–Ekman (A-E) model framework is investigated using high-vertical-resolution radiosonde observations. The reconstructed tensor provides improved agreement between modeled and observed wind profiles compared to classical formulations based on real turbulent exchange coefficient. Instead of the classical A-E ...

We analyze the interaction of a quasi-periodic subsystem, in which two-, three-, and four- frequency quasi-periodic oscillations are possible, with a chaotic subsystem. A discrete version is obtained via the Euler scheme from the corresponding flow model. The dynamics of individual subsystems are discussed, including quasi-periodic bifurcations of invariant tori and the occur rence of ...

Abstract. Long-standing differences in development levels between China’s coastal and inland provinces intensified during the 1980s–1990s, at the early stages of market reforms. In response, from the late 1990s the Сentral government began implementing major development initiatives such as the “Go West”, the “Revitalization of the Northeast,” and the “Rise of Central China,” while in ...

Automated microscopic image analysis is essential for quantitative microbiology, yet manual acquisition and generic recognition models struggle with morphological variability and scene artifacts. We address both ends of this pipeline. First, we present a low-cost, open-source acquisition system, based on an Arduino UNO R3 microcontroller and NEMA 17 stepper motors, that automates focusing, magnification, and ...

Enterprises planning material requirements must account for multiple sources of uncertainty. Considering the impact of yield uncertainty is of prime importance to decision-makers. To mitigate the effects of random yield on the continuity of manufacturing operations, we propose establishing a reserve stock to prevent shortages due to defective items within safety stock levels. If no ...

DreamBooth-style personalization, which often relies on one or a few images, can memorize context (background, pose, lighting) rather than learning the subject’s identity, thereby reducing fidelity and limiting prompt-driven edits. P-LoRA (Probability LoRA) is introduced as a training-time modification that biases diffusion timestep sampling and utilizes importance weights, ensuring that the overall objective remains unchanged. ...

Исследуются свойства оптических покрытий на основе использования упрощенного симулятора ошибок в толщинах слоев покрытий при их напылении. Обосновывается возможность такого подхода. Выводятся аналитические оценки среднеквадратичного значения нормы вектора ошибок и степени коррелированности ошибок в толщинах слоев покрытия. Изучается зависимость среднеквадратичного значения нормы вектора ошибок и свойств покрытия от уровня случайных ошибок в слоях. ...

We develop a new three-party quantum secret-sharing (QSS) protocol based on a three-qubit W state. This protocol encodes the secret-sequence bits using X gates and employs randomly selected Hadamard operations and measurement bases to generate information and security-test rounds. We evaluate the efficiency of the proposed protocol and analyze its security against an internal adversary ...

We investigate a special ansats that allows for an iterative solution of the constant Yang-Baxter equation. Testing this ansatz, we construct four sequences of the constant R-matrices. In each sequence the R-matrices act on the tensor squares of vector spaces of linearly growing dimensions. Each R-matrix also depends on a single complex parameter.
By analyzing the ...

We study complete static manifolds with boundary admitting a nowhere-vanishing static potential. Our main result shows that, under a natural lower bound relating the scalar curvature and the boundary mean curvature, a simple static manifold with boundary must in fact have positive scalar curvature, negative boundary mean curvature, and be compact; we also obtain explicit ...

Clarity of knowledge and reasoning is necessary in many cases. Yet vagueness in scientific thinking related to surprise, curiosity, "ability to engage with not-knowing" (de Freitas) and abductive reasoning is also a crucially important source of scientific creativity which supplements combinatorial logic when dealing with the already known. Starting from studies by C. S. Peirce ...

Not every closed manifold admits an Anosov flow for well-known reasons:
the fundamental group of a 3-manifold M admitting an Anosov flow must
have exponential growth, and M must be universally covered by R3. Nevertheless,
