‘Hedgehog Versus ‘Relatives: Researchers Measure How the Brain Responds to Unexpected Words During Natural Speech
Russian neurophysiologists, including researchers from HSE University, have demonstrated the feasibility of using event-related fields (ERFs) to study brain activity during natural speech perception. The researchers showed that this approach can be applied not only to individual words but also to continuous speech. Their findings indicate that words whose meanings differ significantly from the preceding context require longer processing times. The study also reveals that the brain processes function words in two stages: first, it identifies their grammatical role and then uses this information to predict the next word. The study has been published in Frontiers in Human Neuroscience.

АТОМИСТИЧЕСКОЕ КОМПЬЮТЕРНОЕ МОДЕЛИРОВАНИЕ ГИДРОКАЛЮМИТА КАК АДСОРБЕНТА РАДИОАКТИВНЫХ АНИОНОВ ИЗ ВОДНЫХ РАСТВОРОВ

Russian Journal of Physical Chemistry A. 2022. Т. 96. № 4. С. 535–537.
Glushak A., Tararushkin E., Kalinichev A. G.

Results are presented from atomistic computer modeling of hydrocalumite (cement AFm-phase) with Cl− and I− anions in the interlayer space as a potential adsorbent of radionuclides 36Cl, 129I, 137Cs. Properties of the crystals themselves and the interaction between aqueous solutions of CsCl and CsI and surfaces of crystalline phases are studied. It is shown the adsorption of Cl− is stronger than that of I− on surfaces of hydrocalumite, which can be explained by the difference in ionic radii of hydrated anions.

Stress tensor of inhomogeneous flexible polymer chain solutions beyond the ground-state dominance approximation
Budkov Y., Journal of Chemical Physics 2026 Vol. 165 No. 9 Article 094902
We derive the stress tensor of a flexible polymer solution within the Gaussian-chain self-consistent field theory (SCFT) without invoking the ground-state dominance (GSD) approximation. Starting from a covariant formulation of the single-chain partition function in a background metric, we obtain the symmetric stress tensor expressed through the full Edwards propagators. The result contains the local ...

Metastability of lipid vesicle shapes in uniaxial extensional flow
Pikina E., Physical Review E - Statistical, Nonlinear, and Soft Matter Physics 2026 Vol. 113 No. 5
In this work, we investigate the elastic properties of deflated vesicles and their shape dynamics in uniaxial extensional flow. By analyzing the Helfrich bending energy and viscous flow stresses in the limit of highly elongated shapes, we demonstrate that all stable vesicle configurations are metastable. For vesicles with small reduced volume, we identify the type ...

The ERG (Arase) satellite recently discovered a non-thermal hectometric continuum with a narrowband frequency structure. The mechanism behind the generation of this type of emission in the near-Earth plasma is still unknown. This study examines the potential use of electron cyclotron harmonics instability to explain the line structure of hectometric radio emissions for the first ...

Kobtsev Danil, Albert J., Nitzan M. et al., Applied Sciences (Switzerland) 2026 Vol. 16 No. 17 Article 8577
AIVBVI semiconductors, particularly lead chalcogenides, remain key materials for mid-wave infrared (MWIR) photodetection due to their narrow bandgap and exceptional carrier transport properties. However, the realization of high-quality p-type PbTe thin films, suitable for p–n junction devices, remains a technological challenge. In this work, we report the fabrication of high-mobility p-type PbTe thin films grown on ...

Pyramidal solitons (solitons with more than two inflection points) of the generalized Korteweg–de Vries (KdV) equation are investigated. Necessary and sufficient conditions for the existence of such structures are presented. Within the framework of the generalized Gardner equation — the simplest model that admits pyramidal solitons as solutions — it is shown that these solutions ...

Non-epitaxial perovskite polariton laser diode operating under direct current
Zhukov A., Kryzhanovskaya N., Moiseev E. et al., Nature 2026 Vol. 656 P. 80–85
Reaching lasing in electrically pumped microdevices based on solution-processed semiconductors poses a substantial scientific and technological challenge. Halide perovskites offer a promising platform for electrical injection1, as their optically excited single-crystal cavities2–4 and predesigned5,6 or postprocessed microstructures7,8 have exhibited low lasing threshold. Indirect electrical pumping of a dual-cavity perovskite laser was recently obtained9, using a well-established technological concept of embedding a ...

Understanding the electric double layer at electrode–electrolyte interfaces, Part III: crystallographic-face dependence of silver capacitance in aqueous NaF solutions
Mazur D., Petr E. Brandyshev, Doronin S. et al., Electrochimica Acta 2026 Vol. 577 Article 149729
The electric double layer (EDL) at a single-crystal metal surface is controlled not only by the electrolyte composition and the electrode potential, but also by the atomic structure of the surface itself. This makes the Ag(hkl)/NaF interface a stringent test for continuum theories of the EDL. In the third part of our series, we examine ...

Compression-Induced Lattice Tilting Quenches Ion Migration at Metal Halide Perovskite Grain Boundaries: A Machine Learning Molecular Dynamics Study
Mikhail R. Samatov, Liu D., Emir S. Amirov et al., The Journal of Physical Chemistry Letters 2025 Vol. 16 No. 51 P. 13068–13074
Ion migration at grain boundaries (GBs) is a key issue leading to the performance degradation of metal halide perovskites (MHPs). Given the weak lattice interactions, the properties of MHPs are highly sensitive to external strain, which is inevitable in practical applications. Nevertheless, a fundamental understanding of the GB behavior under strain is still lacking. Using ...

Alzheimer’s disease (AD) pathogenesis is correlated with the membrane content of various lipid species, including cholesterol, whose interactions with amyloid precursor protein (APP) have been extensively explored. Amyloid-β peptides triggering AD are products of APP cleavage by secretases, which differ depending on the APP and secretase location relative to ordered or disordered membrane microdomains.
