‘Our Team Consists of True Leaders in Their Respective Academic Disciplines
The HSE International Centre of Decision Choice and Analysis studies a wide range of methods for analysing decision-making and possible scenarios for the development of natural, socio-economic, and political phenomena using various mathematical models. The application of advanced mathematical methods to forecasting helps to prevent negative outcomes and avoid erroneous decisions. The HSE News Service spoke to the centre’s director, Prof. Fuad Aleskerov, about its work.

Oscillatory Responses to Tactile Stimuli of Different Intensity

Sensors. 2023. Vol. 23. No. 22. Article 9286.
Kuc A., Skorokhodov I., Semirechenko A., Khayrullina G., Maksimenko V., Varlamov A., Гордлеева С. Ю., Hramov A.

Tactile perception encompasses several submodalities that are realized with distinct sensory subsystems. The processing of those submodalities and their interactions remains understudied. We developed a paradigm consisting of three types of touch tuned in terms of their force and velocity for different submodalities: discriminative touch (haptics), affective touch (C-tactile touch), and knismesis (alerting tickle). Touch was delivered with a high-precision robotic rotary touch stimulation device. A total of 39 healthy individuals participated in the study. EEG cluster analysis revealed a decrease in alpha and beta range (mu-rhythm) as well as theta and delta increase most pronounced to the most salient and fastest type of stimulation. The participants confirmed that slower stimuli targeted to affective touch low-threshold receptors were the most pleasant ones, and less intense stimuli aimed at knismesis were indeed the most ticklish ones, but those sensations did not form an EEG cluster, probably implying their processing involves deeper brain structures that are less accessible with EEG.

Linear dependencies, polynomial factors in the Duke–Erdős forbidden sunflower problem
Kupavskii A., Noskov F., Forum of Mathematics, Sigma 2026 Vol. 14 Article 124
We call a family of $s$ sets $\{F_1, \ldots, F_s\}$ a sunflower with $s$ petals if, for any distinct $i, j \in [s]$, one has $F_i \cap F_j = \cap_{u = 1}^s F_u$. The set $C = \cap_{u = 1}^s F_u$ is called the {\it core} of the sunflower. It is a classical result of ...

Modulational Instability and Wave Dynamics in the Rotated Modified Gardner–Whitham Equation
Flamarion M. V., Pelinovsky E., Chaos, Solitons and Fractals 2026 Vol. 213 No. 2 Article 119245
This article concerns the study of modulational instability in the rotated-modified Gardner–Whitham (rmGW) equation. This model incorporates both quadratic and cubic nonlinearities, similarly to the Gardner equation, while also retaining the fully dispersive character of the Whitham equation together with a large-scale dispersive term analogous to that in the Ostrovsky equation. Using a classical multiple-scale asymptotic expansion, we ...

Space-Time Fluctuations in a Quasi-static Limit
Bernardin C., Gonçalves P., Olla S., Mathematical Physics Analysis and Geometry 2024 Vol. 27 No. 7
We consider the macroscopic limit for the space-time density fluctuations in the open symmetric simple exclusion in the quasi-static scaling limit. We prove that the distribution of these fluctuations converge to a gaussian space-time field that is delta correlated in time but with long-range correlations in space. ...

Психологическая трансформационная игра как инструмент снижения тревожности
Сизикова Т. Э., Леонов С. В., Polikanova I., Национальный психологический журнал 2026 Т. 21 № 4 С. 79–89
Background. The relevance of this study is driven by the rapid increase in anxiety disorders in modern society. According to WHO data from 2021, 359 million people worldwide suffered from anxiety disorders. In psychological practice, there is a growing number of techniques being applied, including those aimed at reducing anxiety, but their effectiveness is not always scientifically proven. Thus, ...

To spike or not to spike: the whims of the Wonham filter in the strong noise regime
Bernardin C., Chhaibi R., Najnudel J. et al., Probability Theory and Related Fields 2026 Vol. 195 P. 1823–1875
We study the celebrated Shiryaev-Wonham filter (Wonham, W.M., in J. Soc. Ind. Appl. Math. 347–369, 1964) in its historical setup, where the hidden Markov jump process has two states. We are interested in the weak noise regime for the observation equation. Interestingly, this becomes a strong noise regime for the filtering equations. Earlier results of ...

Explicit Formula for Inverse and Determinant in Geometric Algebras over Odd-dimensional Vector Spaces
Abdulkhaev K., Shirokov D., Advances in Applied Clifford Algebras 2026 Vol. 36 P. 1–21
In this paper, we present explicit formulas for the inverse and determinant in geometric (Clifford) algebras over vector spaces of dimension n = 7. The derivation of these formulas is made possible by generalizing the concept of conjugation to basis conjugation operations. We further develop a general method for constructing such formulas over odd-dimensional spaces ...

HLA class I escape drives the evolution of SARS-CoV-2 in human populations
Ekaterina D. Riumina, Klink G. V., Alekseeva E. et al., PNAS, США 2026 Vol. 123 No. 35 P. 1–20
The role of escape from the cytotoxic T cell (CTL) response in SARS-CoV-2 evolution remains controversial. Here, we study the origin and spread of SARS-CoV-2 variants whose mutations reduce presentation by the HLA class I alleles common in human populations. We find that 35% of mutations that are characteristic of the variants of concern, and ...

Graphon spin systems as exactly solvable models
Medvedev G., Alexandrov Artem, Physical Review E - Statistical, Nonlinear, and Soft Matter Physics 2026 Vol. 114 Article 044102
Graphons are measurable functions used to describe the asymptotic behavior of convergent graph families. Originally motivated by problems in combinatorics and graph theory, graphons have found numerous applications in the modeling and analysis of dynamical processes on networks. In this work, we use graphons to formulate the Ising model on convergent graph sequences, which include ...

The Birman–Williams problem on describing the planetary link of a fibered knot K in S^3 has been partially solved. Using Nielsen's theory for the classification of periodic surface homeomorphisms and its close relationship with the theory of gradient-like diffeomorphisms, it is proved that the planetary link of the trefoil (the unique periodic fibered knot of genus ...

Neurocognitive mechanisms of source credibility: how work experience and patient ratings modulate the processing of medical veracity cues
Monahhova E., Morozova A., Gorodnicheva Y. et al., Frontiers in Human Neuroscience 2026 Vol. 20 Article 1867901
Inroduction:  Source credibility is fundamental to how medical information is processed,yet the underlying neurocognitive mechanisms remain poorly understood. We investigated how two credibility cues — a doctor’s expertise (years of work experience) and aggregate patient ratings (star ratings) — modulate brain responses to veracity cues (‘True’ vs. ‘False’) presented after health- related headlines. Methods:  We recorded EEG from ...

Neural tracking of natural speech in children in relation to their receptive speech abilities
Anton Rogachev, Sysoeva O., Cognitive Systems Research 2024 Vol. 86 Article 101236
Receptive speech is the ability to understand speech addressed to a person. It is a crucial process for a child’s cognitive development. We examine the relationship between receptive speech and neural tracking of natural speech in 52 children aged 3–8 years to infer the neurophysiological mechanisms underlying speech development. We registered a 32-channel electroencephalogram (EEG) ...

Validation of novel naturalistic limb movement stimuli for studying biological motion perception in adults
Koriakina M., Ntoumanis I., Blagoveshchensky E. et al., Frontiers in Human Neuroscience 2026 Vol. 20 Article 1754368
Introduction:  Understanding how we perceive and interpret the movements of other living beings is fundamental to social interaction, survival, and navigating our dynamic environment. Traditional studies of biological motion perception have predominantly employed simplified stimuli, such as point-light displays, which sacrifice ecological validity for experimental control. Methods:  To overcome this limitation, we created a novel stimulus set featuring ...
