Scientists Develop Algorithm for Accurate Financial Time Series Forecasting
Researchers at the HSE Faculty of Computer Science benchmarked more than 200,000 model configurations for predicting financial asset prices and realised volatility, showing that performance can be improved by filtering out noise at specific frequencies in advance. This technique increased accuracy in 65% of cases. The authors also developed their own algorithm, which achieves accuracy comparable to that of the best models while requiring less computational power. The study has been published in Applied Soft Computing.

Fair Division: How Mathematics Helps to Divide the Indivisible
How can items be allocated among participants so that no one feels short-changed? Alexander Karpov, Assistant Professor at the Faculty of Economic Sciences, and his Singaporean colleague, Prof. Warut Suksompong, set out to find a mathematical answer to this question. In this interview, they discuss how a model of rational preferences is constructed, why one cannot rely on a simple sum of values, and where an algorithm that asks a minimal number of questions can be useful.

Electronics of the Future: Why Superconductors and Spintronics Work Together
It was once believed that superconductivity and magnetism avoided each other like the devil avoids holy water. However, modern nanostructures prove the opposite. A Russian theoretical physicist and Indian experimentalists have joined forces to create the electronics of the future—free from energy losses. Nataliya Pugach, Professor at the School of Electronic Engineering at HSE MIEM and Leading Research Fellow at the Quantum Nanoelectronics Laboratory, explains how a long-standing acquaintance in Cambridge grew into a mirror laboratory project with the Indian Institute of Technology Bombay (IIT Bombay), how superconducting spintronics works, and what surprises a researcher in India beyond the university campus.

The Main Factors Influencing the Effectiveness of the Noise-Resistant Method of Information Transmission

P. 300–305.
Dmitrii Artamonov, Nikolay Grachev, Utkin B.

One of the most important indicators of the quality of radio information transmission systems is noise immunity. The most significant impact is caused by interference exceeding the level of the useful signal. In the author's previous work, a method of digital signal processing was published to combat interference of this kind. The article describes a mathematical and software model of two-channel synchronous signal reception with the results in the form of a dependence of the probability of block errors in the transmitted information on the signal / (interference + noise) ratio, where the result of the noise immunity of the system to minus 26.5 dB was achieved. However, like any other method, the proposed one has its weaknesses. This work describes and analyzes the main factors affecting the effectiveness of the method under study.

Тираспольский С.А., Червяков А. В., Труды Научной конференции по радиофизике, ННГУ, 2004 2004 С. 169–171
Диаграмообразование (ДО) в MIMO системах (multiple-input multiple-output systems), одновременно использующих несколько приемопередатчиков на обоих концах линии связи, является достаточно простым способом для повышения пропускной способности и увеличения ОСШ на приемном конце. Для этого в большинстве ранее предлагавшихся методов было необходимо знание на передатчике канальной матрицы или части ее SVD разложения, что требует значительной нагрузки на ...

Recombination mode of extreme ultraviolet radiation in a lithium laser-produced plasma
Gubarev V., Krivokorytov M., Stepanov L. et al., Journal of Applied Physics 2025 Vol. 138 No. 9
This work provides new insights into the emission mechanisms of laser-produced lithium plasma in the extreme ultraviolet (EUV) spectral region, with important implications for the development of EUV light sources. High-resolution spectra of the Li III Lyman series were recorded using a custom-built grazing-incidence spectrometer. The analysis of relative line intensities and profiles allowed us to ...

Bobrov E., Kropotov Dmitry, Lu H. et al., IEEE Communications Letters 2022 Vol. 26 No. 4 P. 818–822
IEEEThe paper describes an online deep learning algorithm (ODL) for adaptive modulation and coding in massive MIMO. The algorithm is based on a fully connected neural network, which is initially trained on the output of the traditional algorithm and then incrementally retrained by the service feedback of its output. We show the advantage of our ...
