Scientists Create Open Dataset for Studying Concentration
A team of Russian researchers, including scientists from HSE University–St Petersburg, has developed the first open multimodal dataset containing recordings of brain activity, heart function, and video observations to help researchers understand what happens in the human brain during deep concentration. In the future, the dataset could accelerate the development of neural interfaces, rehabilitation technologies, and AI systems. The article has been published in Scientific Data.

‘Science Is Universal-It Knows No Borders
Fuad Aleskerov, Tenured Professor and Director of the International Centre of Decision Choice and Analysis at HSE University, together with his colleagues, has developed methods of network analysis in bibliometrics that have made it possible to identify patterns in the appearance and citation of publications in academic journals, as well as their influence on each other. When one or a number of studies are frequently cited by a wide range of journals, this is an indicator that the research is of high quality. By contrast, extensive cross-citation within a limited group of journals increases the likelihood of identifying a network of predatory publications.

SiGe HBT Performance Modeling after Proton Radiation Exposure

P. 274–277.
Petrosyants K. O., Kozhukhov M.

The effects of proton irradiation on SiGe heterojunction bipolar transistor (HBT) are investigated using Synopsys/ISE TCAD tool. To account for the impact of proton irradiation models for carrier lifetime degradation under irradiation are included in the program. The results of modeling the impact of protons of different energies are presented. For SiGe HBT increase in the base current for low-energy protons is more intense than for high-energy protons. We also present the simulation results of SiGe HBT dc and ac performance after proton exposure. The simulation results are in good agreement with experimental data.

Hydrogen Disproportionation Reduces the Bandgap and Prolongs the Carrier Lifetime in Cs2AgBiBr6: Quantum Dynamics Analysis
Emir S. Amirov, Liu D., Samatov M. et al., The Journal of Physical Chemistry Letters 2025 Vol. 16 No. 51 P. 13075–13082
Cs2AgBiBr6 is a promising lead-free double perovskite with excellent stability, but it suffers from a large bandgap for optoelectronic applications. Hydrogenation is reported not only to reduce the bandgap but also to prolong the carrier lifetime in Cs2AgBiBr6, improving device efficiencies significantly. In order to elucidate the mechanisms underlying these phenomena, we combine density functional theory ...
