Transition between metastable equilibria: Applications to binary-choice games
Physical Review E - Statistical, Nonlinear, and Soft Matter Physics. 2023. Vol. 108. No. 2. Article 024134.
Transitions between metastable equilibria in the low-temperature phase of dynamical Ising game with activity spillover are studied in the infinite time limit. It is shown that exponential enhancement due to activity spillover, which takes place in finite-time transitions, is absent in the infinite time limit. In order to demonstrate that, the analytical description for infinite time trajectory is developed. An analytical approach to estimate the probability of transition between metastable equilibria in the infinite time limit is introduced and its results are compared with those of kinetic Monte Carlo simulation. Our study sheds light on the dynamics of the Ising game and has implications for the understanding of transitions between metastable states in complex systems.

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.

The stability of formal concepts and its generalization as robustness are considered in the paper. We use an approximation of stability in the form of Δ-measure for fast calculations. A computationally efficient method for calculating robustness based on subcontexts is presented. We also present a new method to analytically evaluate the number of preimages for ...

For a subfield $\K$ of the field $\C$ of complex numbers, we consider curve and divisorial valuations on the algebra $\K[[x,y]]$ of formal power series in two variables with the coefficients in $\K$. We compute the semigroup Poincar\'e series and the classical Poincar\'e series of a (discrete, rank one) valuation on it. ...

We analyze the Ising model with anisotropic interactions in two dimensions using deep learning neural networks (NN) trained to classify paramagnetic (PM) and ferromagnetic (FM) phases. The spin configurations used as training data are labeled as belonging to either PM state or the FM state using analytically known phase transition temperatures. We use the variation of the output function to ...
