Researchers Develop Method for Direct Generation of Regulatory DNA
Researchers at HSE University have developed a model for generating promoters and enhancers—DNA sequences that regulate gene activity. The model works directly with DNA nucleotides, without first transforming them into a continuous numerical representation. This solution could be useful for applications in synthetic biology and gene therapy. The study results were presented at the ICLR 2026 Workshop ‘Generative AI in Genomics (Gen^2): Barriers and Frontiers.’

Causal Properties of Lorentzian Manifolds and Regular Coverings

Lobachevskii Journal of Mathematics. 2024. Vol. 45. No. 8. P. 3924–3934.
D. A. Maksimov, Yakovlev E.

Regular coverings of Lorentzian manifolds are studied under the assumption that the covering map is isometric and preserves time orientation. Conditions for the covering manifold are obtained that are necessary and sufficient for the base to be chronological, causal, strongly or stable causal, and also globally hyperbolic manifold. As a corollary, statements are obtained that the indicated causal properties rise from the base to the covering manifold. In the general situation the opposite is not true. The connections between splittings of the base and the covering manifold in the case of their global hyperbolicity are also studied.

Изучаются законы взаимности, связанные с комплексными линейными расслоениями на расслоениях на ориентируемые окружности. В частности, доказывается следующий закон взаимности. Пусть B – комплексное многообразие и πi:Mi→B – расслоение на ориентируемые окружности, где индекс i пробегает конечное множество. Пусть Li и Ni – комплексные линейные расслоения на каждом многообразии Mi. Закон взаимности утверждает, что сумма всех элементов (πi)∗(c1(Li)∪c1(Ni)), где (πi)∗ – ...

Orbifold Saito theory of A and D type singularities
Basalaev A., Rarovskii A., Journal of Singularities 2026 Vol. 30 P. 61–80
Saito theory associates to an isolated singularity rich structure that plays an important role in mirror symmetry. In this note we construct Saito theory for A and D type Landau-Ginzburg orbifolds. Namely, for the pairs (f,G), where f defines an isolated singularity of A and D type and G is a group of symmetries of ...

Non-axiomatizability of modal predicate logics of Dedekind-complete linear orders with constant domains
Rybakov M., Shkatov D., Journal of Logic and Computation 2026 Vol. 36 No. 6 Article exag026
We prove Pi-1-1-hardness, and thus lack of recursive axiomatizability, of constant-domain modal predicate logics defined by a class of Dedekind complete linear Kripke frames containing a frame with an infinitely increasing chain of worlds. The result holds even for the language with one unary predicate letter, one propositional letter, and two individual variables. ...

Semi-Interlaced Polytopes
Селянин Ф. И., Moscow Mathematical Journal 2026 Vol. 26 No. 2 P. 167–187
Minkowski mixed volume of n subpolytopes D1,…,Dn of a polytope P⊂Rn clearly does not exceed the normalized volume n!Vol(P). Equality holds if and only if the subpolytopes are interlaced, i.e., each proper face F⊊P intersects at least dim(F)+1 of the polytopes Di. Efficiently computing mixed volumes for more general collections of subpolytopes is crucial for estimating the complexity of numerically solving polynomial systems. Motivated by relaxing the bound dim(F)+1 to dim(F), we ...

A new spin on polynomial relations among kappa classes
Kazaryan M., Dunin-Barkowski P., Bychkov B. et al., International Mathematics Research Notices 2026 Vol. 14 Article rnag146
We prove a recent conjecture of the fourth named author with P. Norbury that states a system of universal polynomial relations among the kappa classes on the moduli spaces of algebraic curves. The proof involves localization and materialization analysis of the spin Gromov–Witten theory of the projective line and is dictated by Z 2 -equivariant ...

We prove that for any initial data on a genus zero spectral curve the cor responding correlation differentials of topological recursion are KP integrable. As an application we prove KP integrability of partition functions associated via ELSV-type formulas to the r-th roots of the twisted powers of the log canonical bundles ...

Сплетенный мир: кошка перевернулась. Доклад Римскому клубу
Gromov V., Переслегин С. Б., Переслегина Е. Б. et al., СПб.: Полакс, 2026.
Механизм происходящих в мире изменений носит эволюционный, а не экологический характер. Иначе говоря, Человечество столкнулось с кризисом развития, который имеет три независимые составляющие: кризис индустриального общества (фазовый кризис), кризис научного мышления (эпистемный кризис) и кризис формата существования разума (социосистемный кризис). Доклад посвящён аспектам этого триединого кризиса и возможным путям его преодоления, не сводящимся к первичному ...

We give a proof of Mukai’s theorem on the existence of certain exceptional vector bundles on prime Fano threefolds. To our knowledge this is the first complete proof in the literature. The result is essential for Mukai’s biregular classification of prime Fano threefolds, and for the existence of semiorthogonal decompositions in their derived categories. Our ...

Full exceptional collections on the symplectic isotropic Grassmannians
Guseva L., Novikov A., Advances in Mathematics 2026 Vol. 503 Article 111211
We prove that the Kuznetsov–Polishchuk exceptional collections on rational homogeneous spaces of the symplectic groups Sp(2n,C) are full and consist of vector bundles. To achieve this, we construct several classes of complexes, which we call generalized staircase complexes, symplectic staircase complexes and secondary staircase complexes — each of which may be of independent interest. ...

Kuznetsov A. P., Sataev I. R., Stankevich N., Chaos 2026 Vol. 36 No. 8 Article 083131
A radio-physical system, namely, a two-mode van der Pol generator, is considered. It is shown that this system demonstrates two types of chaos: with one and two zero Lyapunov exponents. The regions of the second type of chaos are surrounded by bifurcation lines of invariant tori doubling. Quasi-periodic structures of various shapes are embedded within ...

Symbolic Interaction as a Sociology of Concern: Revisiting the Theory of Reflexivity Methodologically
Zaichenko L., Journal for the Theory of Social Behaviour 2026 Vol. 56 No. 1
This paper attempts to revisit the critical realist theory of reflexivity, derived from the pragmatist tradition of symbolic interactionism (SI). It discusses how interactionist sociology, with its emphasis on investigating microstructures through meaning‐making, has formed a critical realist theory of reflexivity that serves as a theoretical bridge between the micro and macro levels—specifically, between ‘subjective ...

Reassessing the metrics of integration: Toward eliminating the blur between theory and statistics to clarify effect sizes, measurement, and causality in acculturation psychology
Grigoryev D., Gallyamova A., Komyaginskaya E., International Journal of Intercultural Relations 2025 Vol. 108 Article 102240
The debate around the integration hypothesis in acculturation research frequently centers on the interpretation of effect sizes. While critics argue that these effects are too small and inconsistent to be meaningful, supporters maintain that they reflect statistically robust and theoretically coherent patterns. This controversy reveals a broader epistemological challenge in psychology: persistent ambiguity regarding what ...

Is Causality Admissible in Phenomenology? A Corrective to Edmund Husserl’s Idea
Kirsberg I. V., Phainomena. Journal of Phenomenology and Hermeneutics 2023 No. 32 P. 203–220
The article rejects the traditional limitation of causality in phenomenology and attempts to demonstrate the mistakes in Edmund Husserl’s arguments for such an understanding, which limited natural causality to the empirical world and confused both natural as well as motivational causality with logical and psychological connections. The specificity of causality is stressed, in order to clarify the main structures of ...

The focus of the paper is a discussion around one of the versions of scientific realism – ontic structural realism (OSR), which has gained popularity due to the development of quantum field theory. According to OSR, individual objects do not exist as ontological primitives. The ontology of objects and their properties is replaced by the ...

Исследуются накрытия в категории расслоений Серра. Под накрывающим отображением одного расслоения на другое понимается морфизм указанной категории, состоящий из накрывающих отображений тотальных пространств и баз. Построены инварианты таких накрытий и доказана теорема существования накрытия с заданным инвариантом. Показано, что из локальной тривиальности базового расслоения следует аналогичное свойство для накрывающего расслоения. ...
