Financial markets of emerging economies are vulnerable to extreme and cascading information spillovers, surges, sudden stops and reversals. With this in mind, we develop a new online early warning system (EWS) to detect what is referred to as ‘concept drift’ in machine learning, as a ‘regime shift’ in economics and as a ‘change-point’ in statistics. ...

The convergence of energy transition and digitalization represents two pivotal trends in the global economy that complement each other. The decrease in carbon dioxide (CO2) emissions is facilitated by larger Internet access and more substantial investments in research and development. This study sheds light on the dual impact of digitalization and innovation on CO2 emissions ...

In process mining, DFG (Directly-Follows Graph) models are popular due to their simplicity and clarity. However, if a process is acyclic but contains concurrent events, standard algorithms for discovering DFG models can generate "fake" cycles that do not actually exist in the event log. These cycles hinder the analysis of information processes, significantly reducing the ...

International science collaboration countries have expanded considerably in recent years; nevertheless, institutional and organizational barriers and challenges continue to undermine the effectiveness of joint research initiatives. This study examines how such barriers are associated with perceived academic and technological outcomes, drawing on a primary dataset of 396 survey responses from researchers in BRICS-countries-based collaborations. The ...

Object-centric process mining has emerged as a powerful paradigm for analyzing event data involving multiple interacting business objects. Existing discovery techniques often rely on object-centric Petri nets with fixed arc multiplicities, limiting their ability to represent parametric resource consumption and production patterns and to capture quantitative dependencies between interacting object types. In this paper, we ...

The paper considers the problem of estimating the coupon-free yield curve of Russian bonds in yuan. The relevance of the topic is explained by the increased popularity of yuan-denominated bonds in the Russian market since 2022, as well as the recent appearance of the first federal loan bonds (OFZ) in yuan. Given that the number ...

This article examines financial innovations in the Russian corporate bond market as a response to structural changes in the economy following 2022. The tightening of monetary policy has led to prohibitively high interest rates for domestic companies, while the sanctions have closed access to external capital markets. Despite these constraints, Russian firms have successfully adapted ...

Purpose
Artificial intelligence (AI) is vastly impacting the digital transformation of societies, economies, businesses, markets and enterprises, at a very fast pace, mostly after the global success of the generative algorithms. In this respect, this study, with an exploratory intention, aims to provide evidence about the fundamental issues of AI, particularly if generative, when adapted to ...

Digital transformation and the possibility to collect large amount of data, the so-called big data, from different sources can lead to the redefinition of business processes, models and infrastructures. In this respect, data-driven decision making (DDDM) emphasizes the need to rethink management practices to view data as a driving force that can improve the effectiveness ...

Cities become more productive and enjoyable places to live with improved transportation management. However, most cities in developing countries still lack it. In this context, the present study examines the relationship between the different types of vehicles (measured by passenger and freight vehicles) and urbanization (measured by city population size and density) in India. We ...

This study explores the role of environmental, social, and governance (ESG) in shaping productive capacity amid economic complexity, economic policy uncertainty, and geopolitical risks for a panel of OECD countries. The period of observations runs from 2003 to 2023. The results based on quantile-on-quantile regression demonstrate that ESG uncertainty has a gradual, progressive positive impact ...

Recent advances in large language model (LLM) agents have shown promise for autonomous decision-making in recommender systems. However, existing approaches suffer from two fundamental limitations: flat agent memories that conflate different information modalities and prohibitive computational costs that prevent scaling beyond a few hundred users. We propose Hybrid-GraphRAG, a recommender system that integrates hierarchical agent ...

Purpose
This study assesses the impact of the European Central Bank's (ECB) Unconventional Monetary Policy (UMP) on economic growth via its effects on sovereign bond yields in the Eurozone. Unlike previous studies that focus on high-frequency data and short-term effects, this study provides evidence on the long-term effects of the ECB's asset purchases on key macroeconomic ...

The carbon balance of an ecosystem is the difference between Gross Primary Productivity (GPP) and Ecosystem Respiration (Reco) as expressed by Net Ecosystem Exchange (NEE). While remote sensing retrievals of GPP have reached maturity, Reco estimation remains underexplored and ultimately cast bias on NEE. Here we present an end-to-end multi-scale analysis of the mechanism of ...

This paper addresses the challenge of merging hierarchical navigable small world (HNSW) graphs, a critical operation for distributed systems, incremental indexing, and database compaction. We propose three algorithms for this task: Naive Graph Merge (NGM), Intra Graph Traversal Merge (IGTM), and Cross Graph Traversal Merge (CGTM). These algorithms differ in their approach to vertex selection ...

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 ...
