HSE Scientists Train Neural Network to 'Hear' Faults in Electric Motors
Researchers at the AI and Digital Science Institute of the HSE Faculty of Computer Science have developed a new method—the Signature-Guided Data Augmentation (SGDA) framework—that achieves 99% accuracy in motor fault detection and 86% accuracy in fault classification. The application of this approach can reduce industrial equipment repair costs, minimise downtime, and improve production safety. The study results have been published in Engineering Applications of Artificial Intelligence.

Is It Possible to Predict a Citys Life Based on the Shape of Its Neighbourhoods?
Is it possible to predict, based on the configuration of streets and buildings, where a café will open or where traffic congestion will occur? Participants in the Spatial Analysis and Modelling of Urban Processes research and study group use open data and machine learning to identify universal patterns. Alexander Sheludkov and Eduard Somov discuss the purpose of comparing cities, the need for new forms of urban statistics, and how open data is transforming approaches to urban studies.

Analysis of the dependence of dimethylmalonate complexes structure on the nature of heterometals by the example of Co(II) и Cd(II) compounds with K and Ba atoms

Journal of Molecular Structure. 2022. Vol. 1256. Article 132532.
Gogoleva N., Zorina-Tikhonova E., Khapaeva P., Shmelev M., Kiskin M.

A series of cobalt(II) and cadmium(II) compounds comprising dimethylmalonate anions combined with potassium and barium ions have been synthesized. The compounds obtained are coordination polymers with 3D structure (1) or 2D structure (2–4). It has been shown that, depending on the nature of heterometals, the type of coordination of dimethylmalonic acid by d-metal atoms changes: from bischelate type (2) and chelate type combined with bridging type (1, 2), to complexes that do not contain six-membered chelate rings with d-metal atoms (3 and 4). Topological analysis of the compounds synthesized showed that the topological motif of structures 1, 2, and 4 is represented by new 4,5,6-coordinated networks, while that of 3 is a new 4,6-coordinated network.

Cu(I) acetylide clusters decorated with pyridylphosphine ligands: structural diversity, cuprophilic interactions and phosphorescence properties
Baranov A., Bagryanskaya I., Novikov A. et al., Inorganic Chemistry Communications 2026 Vol. 189 Article 116670
The reaction of copper(I) phenylacetylide [PhC ≡ CCu]n with the 2-pyridylphosphines (tBu2PyP and Ph2PyP) offers a straightforward route to structurally diverse clusters. With tBu2PyP, a trinuclear cluster [Cu3(C ≡ CPh)3(tBu2PyP)3] featuring a Cu3 triangular was isolated. Surprisingly, the reaction of [PhC ≡ CCu]n with Ph2PyP yields two isomeric clusters [Cu4(C ≡ CPh)4(Ph2PyP)4] with tetrahedral or zigzag-arranged Cu4 cores.

Dipolar [3+2] Cycloaddition of Nitrones to 3-Aroylpyrrolo[2,1-c][1,4]benzothiazine-1,2,4-triones
Khramtsova E. E., A. S. Novikov, Dmitriev M. V., Russian Journal of Organic Chemistry 2026 Vol. 62 Article 12
The dipolar [3+2]-cycloaddition reactions of 3-aroylpyrrolo[2,1-c][1,4]benzothiazine-1,2,4-triones with diarylnitrones lead to the formation of benzo[b]isoxazolo[5',4':2,3]pyrrolo[1,2-d][1,4]thiazines. The reac- tion proceeds stereoselectively to form exclusively the (2aS*,3R*,5aS*) diastereomers. Density functional theory computations for the model reaction showed that the (2aS*,3R*,5aS*) diastereomers are both kinetically and thermodynamically preferred over the alternative (2aS*,3S*,5aS*) diastereomers.
