'I Wish That People Would Place Greater Trust in Science'
When Tatiana Eremicheva chose Fundamental and Computational Linguistics as her field of study, she thought it would be about learning languages. Instead, she discovered it was about helping people. In this interview for the HSE Young Scientists project, she discusses science as a way of understanding the world, billiards as a team-building activity, and why learning to read is not always as easy as it seems.

Immunity to Chaos: How Personal Resources Help Us Cope with the Challenges of a Turbulent World
International conflicts, crises and digital overload—the modern world puts our minds to the test every day. Traditional psychology often focuses on the consequences: anxiety, depression, and psychosomatic disorders. But what if we looked at the problem differently—through the lens of the resources that prevent us from breaking down? Psychological immunity is precisely this set of resources. Alena Zolotareva and her group, Psychological Immunity as a Resource for Positive Functioning, are developing an integrative model of this phenomenon, adapting diagnostic tools and preparing for large-scale empirical research. Why do psychologists need to collaborate with medical professionals, and how could their research transform preventive care in clinics and corporations?

How to Assess Students Knowledge in the Age of AI
A researcher at HSE University has proposed a flowchart to help lecturers decide how to assess students who use artificial intelligence. It shows where the use of AI should be restricted and where it can be incorporated into the learning process. The article has been published in IT Professional.

Rolling stock vibrodynamic impact model on railway pipelines

E3S web of conferences. 2023. Vol. 383. Article 4.
Postnova E. V.

The present paper presents the rolling stock vibrodynamic impact model on railway pipelines, obtained on the basis of experimental studies conducted under field conditions at a railway station. The experimental research program provided for the determination of the effect of vibration-dynamic effects of rolling stock on the working condition of pipes and butt joints by conducting vibration-measuring work on the investigated section of the railway pipeline during the passage of various series of locomotives. The proposed modeling method makes it possible to obtain a correlation function of the oscillatory process of a railway pipeline, on the basis of which a spectral density is constructed to identify the amplitude-frequency range at which a stable resonance region occurs, leading to the destruction of the pipeline.

Evaluation of Correlation Functions and Multi-model Forecasting of Geopotential Height and Temperature in the Troposphere and Lower Stratosphere
Gordin V. A., Smirnov M. A., Russian Meteorology and Hydrology 2025 No. 50 P. 1016–1028
Statistical evaluation of three-dimensional auto- and cross-correlation functions for increments from the first guess was performed to interpolate the complex forecast (postprocessing) of geopotential height and temperature to regular grid points. The forecast fields from the ICON model were used as the first guess. Positive definiteness was provided in the evaluation. The verification of the ...

Influence of anisotropy on the study of critical behavior of spin models by machine learning methods
Sukhoverkhova D., Shchur L., / Series arXiv "math". 2024. No. 2410.14523.
In this paper, we applied a deep neural network to study the issue of knowledge transferability between statistical mechanics models. The following computer experiment was conducted. A convolutional neural network was trained to solve the problem of binary classification of snapshots of the Ising model's spin configuration on a two-dimensional lattice. During testing, snapshots of ...

Inverse resonance problem for Jacobi operators on half-lattice
Korotyaev E., Leonova E. A., Russian Journal of Mathematical Physics 2023 Vol. 30 No. 3 P. 320–344
We solve the inverse problem for Jacobi operators on the half lattice with finitely supported perturbations, in particular, in terms of resonances. Our proof is based on the results for the inverse eigenvalue problem for specific finite Jacobi matrices and theory of polynomials. We determine forbidden domains for resonances and maximal possible multiplicities of real and complex resonances. ...

The collective motions of atoms in the molecular dynamics model of a classical Lennard- Jones monocrystal are studied in the process of heating up to a spinodal decomposition and subsequent cooling of the melt until spontaneous crystallization. A hysteresis in the degree of collectivity of atomic motions is found. A new numerical method based on the use of ...

Building blocks of closed and open string amplitudes
Vanhove P., Zerbini F., , in: Proceedings of Science* T12: Detector R&D and Data Handling. Vol. 398: The European Physical Society Conference on High Energy Physics (EPS-HEP2021) .: Sissa Medialab Srl, 2022.
In this text we review various relations between building blocks of closed and open string amplitudes at tree-level and genus one. We explain that KLT relations between tree-level closed and open string amplitudes follow from the holomorphic factorisation of conformal correlation functions on conformal blocks. We give a simple hands-on evaluation of the 𝛼 0 ...

Exactly solvable single-trace four point correlators in χCFT4
Derkachov S. E., Olivucci E., Journal of High Energy Physics 2021 Article 146
In this paper we study a wide class of planar single-trace four point correlators in the chiral conformal field theory (χCFT4) arising as a double scaling limit of the γ-deformed NN = 4 SYM theory. In the planar (t’Hooft) limit, each of such correlators is described by a single Feynman integral having the bulk topology of a square ...
