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.

Cation and oxyanion doping of layered perovskite BaNd2In2O7: Oxygen-ion and proton transport

International Journal of Hydrogen Energy. 2023. Vol. 48. No. 59. P. 22522–22530.
Tarasova N., Bedarkova A., Animitsa I., Abakumova E.

Proton-conducting electrochemical devices such as protonic ceramic fuel cells and pro- tonic ceramic electrolysis cells play a major role in the creation of eco-friendly “green” energy systems. The most studies of proton-conducting materials for these devices are barium cerate zirconates. The layered perovskites are novel class of proton-conducting materials. In this paper, the possibility of cation and oxyanion doping of layered perovskite BaNd2In2O7 was carried out for the first time. The most conductive composition BaLa1.9Sr0.1In2O6.95 demonstrates protonic conductivity value 2*10^-5 S/cm at 450 ◦C. The acceptor-doped two-layer perovskites are the prospective class of proton-conducting materials, and further modification of their composition opens up a new way in the design of solid oxide protonic conductors.

Cu(I) acetylide clusters decorated with pyridylphosphine ligands: structural diversity, cuprophilic interactions and phosphorescence properties
Novikov A., Inorganic Chemistry Communications 2026 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. Upon prolonged storage in acetonitrile, the tetrahedral Cu4 cluster converts to ...

Dipolar [3+2] Cycloaddition of Nitrones to 3-Aroylpyrrolo[2,1-c][1,4]benzothiazine-1,2,4-triones
Novikov A., 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. At room temperature in solution, the ...

Modeling cosolvent effects on solubility in supercritical CO2 using data-driven approaches
Makarov D. M., Kalikin N., Gurikov P. et al., Journal of Supercritical Fluids 2026 Vol. 235 Article 106979
Supercritical CO2 (scCO2 ) is an environmentally friendly solvent, but its low polarity limits the solubility of polar compounds. Cosolvents are commonly used to enhance solvation capability, yet comprehensive datadriven studies are scarce. We compiled the largest dataset to date — 4401 experimental solubility records with 22 cosolvents for 93 nonionic solutes, plus 4855 records ...

Theory of capillary-induced self-coacervation in zwitterionic polymer solutions
Kalikin N., Брандышев П. Е., Budkov Y., Journal of Chemical Physics 2026 Vol. 164 Article 154904
This study presents a mean-field theory for zwitterionic polymer solutions confined within attractive slit-like nanopores. Building upon our prior model for self-coacervation [Budkov et al., Soft Matter 19, 3281–3289 (2023)], we demonstrate that strong electrostatic dipole–dipole correlations between monomeric units, coupled with attraction to pore walls, can induce capillary-driven liquid–liquid phase separation inside the pore—a ...

Combining materials design and deep learning: AI-enhanced luminescence thermometry with a novel Eu3+/Tb3+polymeric coordination compound
Polikovskiy T., Gontcharenko V., Korshunov V. et al., Materials Chemistry Frontiers 2025 Vol. 9 No. 23 P. 3443–3459
Conventional thermal sensors often face limitations due to their reliance on direct contact and restricted measurement ranges, leading to the emergence of novel techniques like luminescence thermometry. However, sensitivity of luminescent thermometers is limited by the only used Boltzmann-based Mott–Seitz model, which is imperfect.

Xu Z., Guo Z., Zhang P. et al., Journal of Materials Chemistry A 2025 Vol. 13 No. 41 P. 35284–35291
GeTe is a promising mid-temperature thermoelectric material that exhibits excellent thermoelectric performance. However, the rhombohedral-to-cubic phase transition occurring near 700 K causes a change in the coefficient of thermal expansion, leading to internal stresses in the device and affecting its working efficiency.
