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.

'The Humanities Serve as a Conscience'
Maria Mizernaia studies Soviet literature and the history of book publishing. In this interview for the HSE Young Scientists project, she discusses plans to publish a novel about besieged Leningrad, AI-provoked reflections on what it means to be human, and how novels can help satisfy our dopamine hunger.

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.

Спин-флуктуационный переход в неупорядоченной модели Изинга
Bogoslovskiy N. A., Петров П. В., Аверкиев Н. С., Письма в Журнал экспериментальной и теоретической физики 2021 Т. 114 № 5-6(9) С. 383–390
A model of an impurity system in semiconductors consisting of spins randomly distributed in space with a hydrogen-like distance dependence of the exchange energy in the Ising Hamiltonian has been studied. The distribution function of the exchange energy and the mean square of the magnetic moment have been calculated as functions of the concentration. It ...

Dynamical spin susceptibility of a spin-valley half-metal
Khokhlov D. A., Rakhmanov A. L., Rozhkov A. V. et al., Physical Review B: Condensed Matter and Materials Physics 2020 Vol. 101 No. 23 P. 235141
A few years ago we predicted theoretically that in systems with nesting of the Fermi surface the spin-valley half-metal has lower energy than the spin density wave state. In this paper we suggest a possible way to distinguish these phases experimentally. We calculate the dynamical spin susceptibility tensor for both states in the framework of ...

Phonon anomaly in Sm2BaNiO5
Klimin S. A., Popova E., Popova M. N., Journal of Physics: Conference Series 2019 Vol. 1389 No. 1 P. 012039
We present low-temperature far-infrared study of Sm2BaNiO5. The lowest-frequency phonon of Sm2BaNiO5 generated by the motion of the Sm3+ ion demonstrates anomalous behaviour at temperatures lower than the Néel temperature, T<TN=55 K. This phonon hardens at the magnetic ordering although its frequency shift does not follow the magnetic order parameter. The observed phenomenon is responsible for ...

Self-Consistent Four-Particle Cluster Model of Fe3+ Heisenberg Chains: Spectral and Magnetic Properties of YFe3(BO3)4 Crystals
Malkin B., Elena A. Popova, Chukalina E. et al., Physica Status Solidi - Rapid Research Letters 2020 Vol. 14 No. 3 P. 190063-1–190063-5
Magnetic properties of antiferromagnetic quasi‐one‐dimensional YFe3(BO3)4 crystals are studied based on the analysis of the measured optical spectra of the Fe3+ ions in different rare‐earth iron borates and self‐consistent four‐particle cluster approach to helical iron chains. Parameters of crystal fields affecting the Fe3+ ions are calculated in the framework of exchange charge model. Parameters of ...

Термодинамика симметричной спин-орбитальной модели: одномерный и двумерный случаи
Валиуллин В. Э., Михеенков А. В., Kugel K. et al., Письма в Журнал экспериментальной и теоретической физики 2019 Т. 109 № 8 С. 557–563
The specific heat and susceptibilities for the two- and one-dimensional spin–orbital models are calculated in the framework of a spherically symmetric self-consistent approach at different temperatures and relations between the parameters of the system. It is shown that, even in the absence of the long-range spin and orbital order, the system exhibits features in the behavior of thermodynamic ...

Исследованы процессы образования нанокластеров, связанные с введением атомов магнитного компонента — хрома и марганца — в гранецентрированную кубическую решетку шпинели CdIn2S4 и тетрагональную решетку халькопирита CuInSe2, соответственно. Рассчитана вероятность существования кластеров различного типа в зависимости от концентрации магнитного компонента. Получены концентрационные зависимости числа кластеров и температурные зависимости обусловленной ими магнитной восприимчивости спиновых стекол CdIn2S4: Cr ...
