Researchers Develop Methodology to Assess the Quality of Legal Representation in Criminal Proceedings
Having a good defence attorney in criminal proceedings can largely determine whether a defendant retains their freedom, health and good name. Researchers at HSE University propose a method for predicting an attorney’s performance based on the outcomes of their previous cases. The methodology takes into account the severity of the charges, the complexity of the cases, and the most likely outcome, drawing on judicial statistics.

Algebra, Geometry, and AI: Russian and Vietnamese Mathematicians Discuss Current Research
A delegation of scientists from Hanoi visited the HSE Faculty of Computer Science and then took part in a Russian-Vietnamese conference in St Petersburg. The events were part of the three-year project ‘Flexibility and Computational Methods.’ Over the course of the project, the researchers have prepared joint publications and obtained new mathematical results.

When Pictures Hinder Understanding: Illustrations May Impede Learning of Abstract Ideas
Illustrations can help remember specific actions but do not always make abstract ideas easier to learn. Researchers from HSE University and Humboldt University compared how people learn from texts with different levels of abstractness. They found that participants remembered illustrations better and performed better on related tasks after reading a multimedia text about yoga asanas than after reading an abstract text about the Nash equilibrium. The findings could help improve the selection of illustrations for educational and informational materials. The study has been published in Learning and Instruction.

Optimal nonrecursive datalog rewritings of linear TGDs and bounded (Hyper)Tree-width queries

P. 1–12.
Bienvenu M., Kikot S., Kontchakov R., Ryzhikov V., Zakharyaschev M.

Our concern is answering ontology-mediated queries (Ο q), whereΟ is a set of linear tgds and q a conjunctive query (CQ) of bounded hypertree width. Assuming that the arity of predicates is bounded, we show that polynomial-size nonrecursive Datalog rewritings can be constructed and executed in (i) LOGCFL for OMQs with ontologies of bounded existential depth; (ii) NL for OMQs with ontologies of bounded depth and CQs whose hypertree decompositions have a bounded number of leaves; (iii) LOGCFL for OMQs with acyclic CQs whose join trees have a bounded number of leaves.

An LLM-Based Approach for Creating Multi-agent Systems
Rezunik L., Alexandrov D., Mikhail Prozorskiy, , in: Intelligent Decision Technologies. Proceedings of the 17th KES-IDT 2025 ConferenceVol. 450.: Springer, 2026. P. 81–91.
Multi-Agent Systems (MAS) can benefit from Large Language Models (LLMs), but hallucinations pose risks to decision-making. This paper introduces an approach for creating MAS based on LLMs and proposes a generalized architecture for such systems. We ensure that reasoning is conducted through predicate logic to minimize errors, and LLMs are exclusively utilized to translate natural ...

Перверсивные интерфейсы: зияние, дрейф и пульсации как онтологические стили в компьютерных играх
Очеретяный К. А., Галактика медиа: журнал медиа исследований 2026 Т. 7 № 2 С. 85–102
We use interfaces to disconnect from the situation around us, from the persistent experience of the outside world, from our neighbors. It is this ability of interfaces to legitimize “absence” that is usually overlooked in their analysis, as the emphasis is on concentration, management, and control. In reality, interfaces are not so much pragmatic and ...

A machine learning dataset on winter roads of Krasnoyarsk Krai, Russia for the forestry and infrastructural projects
Ekaterina S. Podolskaia, Sinitsina A., European Journal of Forest Engineering 2026 Vol. 12 No. 1 P. 7–22
Machine learning in transport modeling has become a trend in science and industry. In this paper, we observe its main directions and focus on a dataset of seasonal road creation. Seasonality as a parameter in transport modeling has a significant impact on transport scenarios but is underestimated worldwide and in Russia, despite modern data challenges. ...

Использование реактивных сред для вычислительных экспериментов в химии и материаловедении
Glushko A., Neznanov A., В кн.: Перспективные материалы и технологии (ПМТ-2025) : Сборник докладов Национальной научно-технической конференции с международным участием, Москва, 07–12 апреля 2025 года.: М.: РТУ МИРЭА, 2025. С. 651–657.
Most of scientific research involves the use of computational tools, while researchers have low IT competences. The efficiency of working with computational modules for scientific research can be significantly increased by guaranteeing reproducibility, interactivity, and reusability of producing artifacts. This can be achieved by using a reactive environment with a standardized set of UI controls, ...

Ludosis in Video Game Ontology or How to Live within a Mess
Абу Махади А. М., Пащенко М. О., Галактика медиа: журнал медиа исследований 2025 Т. 1 № 8 С. 225–253
From its very beginning, the field of game studies is haunted by the question of video game ontology: what is a game and what are its fundamental components? Numerous authors, such as Ian Bogost and Alex Gekker, have written on the impossibility of establishing an exhaustive ontology of games. At the same time, game design ...

Computational Model for Parsing Expression Grammars
Alexander Rubtsov, Chudinov N., , in: 49th International Symposium on Mathematical Foundations of Computer Science (MFCS 2024).: Leibniz International Proceedings in Informatics (LIPIcs), 2024. Ch. 80 P. 80:1–80:13.
We present a computational model for Parsing Expression Grammars (PEGs). The predecessor of PEGs top-down parsing languages (TDPLs) were discovered by A. Birman and J. Ullman in the 1960-s, B. Ford showed in 2004 that both formalisms recognize the same class named Parsing Expression Languages (PELs). A. Birman and J. Ullman established such important properties ...

Existential Threat as a Casus Belli
Kucherenko S., Conatus - Journal of Philosophy 2023 Vol. 8 No. 2 P. 299–312
Existential threat is often mentioned in political rhetoric. While it is mostly used to denote threats to humanity as a whole, like climate change or AI, it is also used on a smaller scale. Existential threat to a state or a similar entity is often evoked too. Such a threat is considered grave enough to ...

On the Epistemological-Ontological Transition Made by Illusionism and Realism
Gorbachev M., Философия. Журнал Высшей школы экономики 2023 Vol. 7 No. 4 P. 199–214
The article is about the discussion between realists and illusionists on phenomenal consciousness, phenomenal properties or qualia. The author considers what he calls epistemological-ontological transition made by illusionists and realists – transition from epistemologically significant statements to ontologically significant ones. The option to avoid such transition is tested in order to overcome some obstacles that ...

R&D projects often fail to meet predetermined deadlines and budgets, which is due not only to poor organization of the research and development pro- cess, but also to the complexity of performance and efficiency evaluation. The evaluation of effectiveness is complicated by the fact that the final result is made up of a sequence of ...
