HSE Researchers Show How Congenital Motor Disorders Affect Brain Development
Researchers from HSE University’s Institute for Cognitive Neuroscience have synthesised the findings of their previous studies on brain development in children with obstetric brachial plexus palsy and arthrogryposis. Their analysis shows that impaired motor function in early childhood not only limits children’s motor experience but also affects memory, categorical thinking, and information processing. The study has been published in Frontiers in Psychology.

Window into the Body: Scientists Develop Neural Network to Detect Risk of 15 Diseases from Retinal Images
Russian universities, with the participation of HSE University, Sber, and Z-union, have developed a neural network that can simultaneously assess the risk of 15 types of pathology from retinal photographs, including not only eye diseases but also cardiovascular conditions. The AI system can help clinicians detect potentially concerning changes at an early stage, identify signs reflecting the condition of retinal blood vessels, and determine whether a patient may need further examination. The paper has been published in Frontiers in Medicine.

'We Did Not Limit the Time for Questions'
The International Laboratory for Supercomputer Atomistic Modelling and Multi-Scale Analysis at HSE University held a major conference on molecular dynamics. Participants had the opportunity to attend all the presentations, while speakers were given as much time as they needed to answer questions. The HSE News Service interviewed Grigory Smirnov, Head of the Laboratory, and Genri Norman, Chief Research Fellow, about the conference preparations and the discussions it generated.

Improved measurement of Born cross sections for chi_bJ omega and chi_bJ (pi+ pi- pi0)non-omega (J = 0, 1, 2) at Belle and Belle II

Journal of High Energy Physics. 2026. Vol. 04. Article 101.
Uglov T., Pakhlov P., Bodrov D., Aushev Т., Adachi I.

We study the processes chi_bJ omega and chi_bJ (pi+ pi- pi0)non-omega (J = 0, 1, 2) at center-of-mass energies sqrt(s) from 10.73 to 11.02 GeV using a 142.5 fb^-1 data sample collected with the Belle detector at the KEKB asymmetric-energy e+e- collider; and at sqrt(s) ~ 10.75 GeV using a 19.8 fb^-1 sample collected with Belle II at SuperKB. We find that the Upsilon(10753) state decays into chi_bJ omega but not into chi_bJ (pi+ pi- pi0)non-omega, while the Upsilon(10860) state, in contrast, decays into chi_bJ (pi+ pi- pi0)non-omega but not into chi_bJ omega. The mass and width of the Upsilon(10753) state are measured to be (10756.1 +/- 3.4(stat.) +/- 2.7(syst.)) MeV/c^2 and (32.2 +/- 11.3(stat.) +/- 14.9(syst.)) MeV. The products of the partial width to e+e- and branching fractions for Upsilon(10753) -> chi_b1 omega and Upsilon(10753) -> chi_b2 omega are (1.57 +/- 0.27(stat.) +/- 0.22(syst.)) eV and (1.39 +/- 0.41(stat.) +/- 0.33(syst.)) eV.

Markovian reduction and exponential mixing in total variation for random dynamical systems
Kuksin S., Shirikyan A., Journal of Dynamics and Differential Equations 2026 P. 1098–1100
The paper deals with the problem of large-time behaviour of trajectories for discrete-time dynamical systems driven by a random noise. Assuming that the phase space is finite-dimensional and compact, and the noise is a Markov process with a transition probability satisfying some regularity hypotheses, we prove that all the trajectories converge to a unique measure ...

Small area quantum-dot stripe lasers with focused-ion-beam-etched mirrors
Obraztsova Anna, Fominykh Nikita, Komarov Sergey et al., Applied Physics Letters 2026 Vol. 129 Article 132110
Miniaturization of edge-emitting quantum-dot lasers is hampered by increased mirror losses in ultra-short Fabry–Perot cavities and limited modal gain of quantum dots (QDs). Here, we demonstrate electrically injected InGaAs/GaAs quantum-dot stripe lasers with an 8-lm stripe width and focused-ion-beam (FIB)-etched mirrors defining cavity lengths from 300 to 77 lm. The laser cavities were fabricated using ...

Conditions for the emergence of pyramidal solitary waves (solitary waves possessing more than two inflection points) are presented for a family of generalized Korteweg – de Vries (KdV) equations.

Benchmarking exchangecorrelation functionals and van der Waals treatments for materials relevant to diamond-like carbon deposition

Amorphous carbon coatings, including diamond-like carbon (DLC), exhibit a wide range of structural and mechanical properties governed by the local bonding topology (the sp2/sp3 ratio), as well as by deposition conditions and substrate material. Recently, machine-learning interatomic potentials trained predominantly on density functional theory (DFT) reference data have significantly advanced multiscale modeling of amorphous carbon ...
