A Kaizen perspective for managing human-technology continuous improvement in the digital age

Purpose The paper examines how digital technologies are transforming continuous improvement (CI) by altering the cognitive and relational dynamics that have long underpinned Kaizen-oriented learning. Design/methodology/approach This paper adopts a conceptual approach, drawing on...

KP integrability of non-perturbative differentials

We prove the KP integrability of non-perturbative topological recursion, which can be considered as a formal ℏ -deformation of the Krichever construction of algebro-geometric solutions of the KP hierarchy. This property goes back to a 2011 conjecture of Borot and Eynard.

Limits of Rauzy graphs of languages with subexponential complexity

To a subshift over a finite alphabet, one can naturally associate an infinite family of finite graphs, called its Rauzy graphs. We show that for a subshift of unbounded subexponential complexity, the Rauzy graphs converge in the sense of Benjamini–Schramm if and only if their emp...

Where unicorns come to life: conditions of entrepreneurial ecosystems and the emergence of disruptive ventures

Purpose Unicorns are startups that rapidly achieve a market value of at least one billion USD. Recently, they are increasingly seen as a key outcome of thriving entrepreneurial ecosystems. However, it remains unclear what elements of entrepreneurial ecosystems contribute to the g...

Spreading and mitigation of extreme events among multilayer neuronal networks: Role of time-varying interaction

The complex network approach is widely used to uncover the propagation of information or events, such as disease outbreaks, rumors, and cascade failures, across several disciplines. In this study, we explore the spreading of extreme events between the multiplex neuronal networks...

A Spatial Assessment of the Production and Economic Performance of the Agro-Industrial Complex in the North Kazakhstan Region

Agricultural planning at the district level requires a transparent comparison of investments, production, financial returns, and resource availability. This study evaluates the relative production and economic performance of 13 districts in the North Kazakhstan Region based on se...

Long intervals of consecutive composite values of polynomials

Let $f\in\mathbb Q[t]$ be an irreducible polynomial of positive degree with positive leading coefficient, taking integer values at every integer. We prove that there is a constant $c_f>0$ such that, for every sufficiently large real $X$, the interval $(X/2,X]$ contains at least $...

Mate-retention capacity and singlehood: evidence from the Greek, Russian, and Ukrainian cultural contexts

Evolutionary theorizing indicates that people vary considerably in their capacity to retain intimate partners, and part of this variation may contribute to singlehood. Candidate items were generated with AI tools and refined by the authors into an instrument to measure this capac...

Designing the waiting experience: How order tracking shapes consumer engagement and loyalty

The post-purchase waiting period is an important yet underexamined stage of the digital customer journey. Consumers increasingly interact with order tracking systems during this phase, yet research has treated tracking primarily as a logistics tool rather than an experiential tou...

On Goncharov's conjecture in next to Milnor degree

Let K be a field of characteristic zero. We prove that its motivic cohomology of weight m and degree m − 1 is rationally isomorphic to the cohomology of the polylogarithmic complex. This gives a partial extension of A. Suslin's theorem describing the indecomposable K 3 of a field...

Generative AI and the balance of effort in group tasks: Appropriate, over-, and under-scaffolding

Generative artificial intelligence (Gen-AI) is increasingly used in higher education, yet its role in collaborative learning remains unclear. This study examines how students use Gen-AI during group lesson-planning tasks in an undergraduate education course. Drawing on Vygotsky’s...

When public money speaks: local government special bonds and corporate green innovation in China

Public investment reallocates both resources and expectations. This study examines this dual role through China’s local government special bonds, a project-based fiscal instrument that reveals local governments’ green development priorities through observable and spatially target...

Corporate Governance and Firm Value in BRICS: A Cross-Country Analysis of Board Structure, Ownership, and ESG Practices

This study examines the relationship between corporate governance and firm value across the BRICS economies Brazil, Russia, India, China, and South Africa using a sample of 46 large-cap listed firms. We construct a composite Corporate Governance Index (CGI) incorporating board st...

Pairings on the Algebra of Laurent Series over a Ring

We prove that continuous $A$-bilinear pairings on the ring of Laurent series that are invariant under continuous automorphisms coincide, up to a constant, with the pairing given by the residue of a differential form over any commutative associative ring with identity.

Urban infrastructure and its role in shaping Moscow’s residential real estate market

Purpose This paper analyzes the apartment prices in Moscow using geographically weighted regression (GWR) to account for the spatial non-stationarity and local variations in the pricing of Moscow’s heterogeneous real estate market on the sample of 3,504 flats. The results suggest...

An Asymptotic Version of the Parametrix Method for Markov Chains Converging to Diffusions

Abstract The paper provides a generalization of the local limit theorem on the convergence of inhomogeneous Markov chains to the diffusion limit for the case in which the corresponding coefficients of the process satisfy weak regularity conditions and coincide only asymptotically...

Improving cost assessment and health economic evaluation of a new medical technology during clinical approbation: the role of a structured costing tool

Objective. To improve cost assessment and health economic evaluation of a new medical technology during clinical approbation. Material and methods. We reviewed the scientific literature on the implementation of clinical approbation (CA) published between 2015 and 2025 and conduct...

Exact screening constraints for theories of inhomogeneous electrolytes: Generalized Stillinger–Lovett relations and a nonlinear Ward hierarchy

Exact theories of electrolyte structure must satisfy the nonlocal constraints imposed by electrostatic screening, yet these constraints are most commonly formulated only for homogeneous bulk systems and at the level of two-point correlations. Here, we develop a unified field-theo...

AlphaZeroBeta: deep reinforcement learning for market-neutral portfolios

Abstract Market-neutral portfolios aim to generate consistent returns while offsetting systematic market risk. Traditional approaches based on factor models or convex optimization often underperform during market regime shifts or when structural assumptions break down. We propose...

EXPRESS: Individual variability in reliance on semantic heuristics: Cognitive and psycholinguistic factors

Recent psycholinguistic research shows strong evidence that sometimes sentences are comprehended via good-enough processing (for example, based on semantic heuristics) rather than algorithmic syntactic analysis. However, little is known about individual differences in reliance on...
