Biologists Discover Unique Properties of MiR-93-5p MicroRNA in Prostate Cancer
Researchers at the International Laboratory of Microphysiological Systems of the HSE Faculty of Biology and Biotechnology investigated how different isoforms of the same microRNA influence gene function in prostate adenocarcinoma. The study found that in some cases, microRNAs can reinforce each other’s effects by targeting and suppressing the same genes. This finding offers a fresh perspective on the molecular mechanisms underlying tumour development and on the search for disease biomarkers. The results have been published in PeerJ.

HSE Economists Use Search Queries to Forecast Birth Rates
Researchers from the HSE Faculty of Economic Sciences have shown that the accuracy of birth rate forecasts for Russia can be improved by almost 50% by incorporating the dynamics of online search queries related to pregnancy and childbirth into forecasting models. In the best-performing models, the forecasting error fell from 4.6% to 3.2%. The findings have been published in Populations and Economics.

Circular Fleitas scheme for gradient-like flows on the surface

Regular and Chaotic Dynamics. 2023. Vol. 28. No. 6. P. 865–877.
Vladislav D. Galkin, Elena V. Nozdrinova, Olga V. Pochinka

In this paper, a classification of gradient-like flows on arbitrary surfaces is obtained by generalizing the circular scheme of Fleitas. In 1975, he proved that such a scheme is a complete invariant of topological equivalence for polar flows on 2- and 3-manifolds. In this paper, we generalize the concept of a circular scheme to arbitrary gradient-like flows on surfaces. We prove that the isomorphism class of such schemes is a complete invariant of topological equivalence. The paper also exhaustively solves the question of the feasibility of an abstract circular scheme with a gradient-like flow on the surface. In addition, an efficient algorithm for distinguishing the isomorphism of circular schemes is constructed.

Задачи бесконечной регулярной реализуемости
Шиманогов И. Н., Vyalyi M., Дискретный анализ и исследование операций 2025 Т. 32 № 4 С. 213–230
A well-studied class of algorithmic problems is that of regular realizability: checking the non-emptiness of the intersection of a regular language with a given language. This problem has a natural algebraic interpretation: verifying whether an element of a Boolean algebra belongs to the kernel of a certain homomorphism. This motivates the consideration of an analogous ...

Statistical inference based on band-limited kernels: Rational-infinitely divisible distributions and beyond
Panov V., Ryabchenko A., / Series arXiv "stat.ME". 2026. No. 2607.05048.
This paper investigates the problem of statistical inference for a mixture distribution consisting of a discrete and a continuous component, with a particular focus on the class of rational-infinitely divisible distributions. We consider non-parametric estimation of both components of the mixture as well as the quasi-L{é}vy measure, assuming that the mixture belongs to the class ...

We investigate the spatial overlap of successive spin configurations in Markov chain Monte Carlo simulations using the local Metropolis algorithm and the Swendsen-Wang and Wolff cluster algorithms. We examine the dynamics of these algorithms for models in different universality classes: Ising model, Potts model with three components, and four-state Potts model. The overlap of two ...

On Ω-stable 3-diffeomorphism with a solid or thickened surfaced basic set
Pochinka O., Barinova M., Journal of Geometry and Physics 2026 Vol. 228 P. 1–8
In the present paper we consider an Ω-stable 3-diffeomorphism with a solid or thickened surfaced non-trivial basic set. Such basic sets include, for instance, all one-dimensional expanding attractors and those two-dimensional basic sets that are not expanding. We prove that the chain recurrent set of every such a diffeomorphism necessarily contains at least two non-trivial ...

Пусть симплекс с целочисленными вершинами - содержащий ровно одну целочисленную точку, отличную от своих вершин. В работе доказывается, что если точка находится во внутренности симплекса или в относительной внутренности некоторой гиперграни симплекса, то объем симплекса ограничен величиной, зависящей только от размерности, в противном случае объем симплекса может быть сколь угодно большим.

Topological Classification of Polar Flows on Four-dimensional Manifolds
Elena Ya. Gurevich, Ilya A. Saraev, Regular and Chaotic Dynamics 2025 Vol. 30 No. 2 P. 254–278
S.~Smale has shown that any closed  smooth manifold admits a gradient-like flow, which is a structurally stable flow with a finite non-wandering set. Polar flows are a specific type of gradient-like flows characterized by the simplest non-wandering set for the given manifold, consisting of exactly one source, one sink, and a finite number of saddle ...

Morse index of saddle equilibria of gradient-like flows on connected sums of S^{n−1}×S^1
Grines V., Gurevich E., Максименко С. И., Working papers by Cornell University. Series math "arxiv.org" 2021
Let M be either n-sphere S^n or a connected sum of finitely many copies of S^{n−1}×S^1, n≥4. A flow f^t on M is called gradient-like whenever its non-wandering set consists of finitely many hyperbolic equilibria and their invariant manifolds intersects transversally. We prove that if invariant manifolds of distinct saddles of a gradient-like flow f^t on M do not intersect each other (in other words, f^t has no heteroclinic intersections), then  dimension ...
