Scientists Develop Algorithm for More Reliable Processors in Data Centres
Researchers from HSE MIEM and Samara University have developed the LRF-3D algorithm to automatically bypass idle nodes in three-dimensional networks-on-chip. Thanks to its hierarchical architecture, the algorithm outperforms existing solutions in both speed and path accuracy, improving processor reliability for use in data centres, supercomputers, and AI computing. The source code and test results are publicly available.

Researchers Develop Method for Direct Generation of Regulatory DNA
Researchers at HSE University have developed a model for generating promoters and enhancers—DNA sequences that regulate gene activity. The model works directly with DNA nucleotides, without first transforming them into a continuous numerical representation. This solution could be useful for applications in synthetic biology and gene therapy. The study results were presented at the ICLR 2026 Workshop ‘Generative AI in Genomics (Gen^2): Barriers and Frontiers.’

Aggregation of Rating Systems for Emerging Financial Markets

Ch. 4. P. 93–119.
Grishunin S., Dyachkova N., Karminsky A. M.

This paper examines the issues of the aggregation and comparison of the credit ratings of various economic agents for risk management purposes in a commercial bank. The empirical results of the study make it possible to increase the assessment of credit risks based on the constructed system of aggregating credit ratings for industrial companies and commercial banks. The work also confirms the relationship between the level of assigned credit ratings and the various phases of the credit cycle. The dynamics at the macroeconomic level shows that the credit ratings of various economic agents change in different directions and are out of sync with time correlation of credit cycles in various phases. The main scientific result of the study is an aggregate-based approach for credit risk evaluation of various economic agents and to develop the quantitative methods for assessing the relationship between the level of credit ratings and the credit cycle.
