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.

HSE Researchers Discover Who Eats Out in Russia-And Why
Around one-third of Russians (31.3%) rarely eat out or buy ready-made meals. The core group of active consumers—those who eat out or purchase prepared food almost every day or several times a week—accounts for only about 9% of the population. These are the findings of a study conducted by the HSE Institute for Social Policy. According to the researchers eating out is no longer a marker of high social status in Russia.

Анализ погрешности измерений показателя преломления с помощью автоколлимационного гониометра

Физические основы приборостроения. 2025. Т. 14. № 2(56). С. 70–73.
Yurin A., Krasivskaya M.

The paper considers the error of the autocollimation method for measuring the refractive index of triangular prisms and its comparison with the error of the modified method, in which autocollimation occurs from an additional mirror mounted on the path of the beam refracted by the prism. The analysis of the dependence of the measurement error on the angle of the prism and the position of the additional mirror is given, and recommendations for the desired beam deviation angles are developed. It is shown that the use of an additional mirror increases the accuracy of autocollimation method up to 2 times due to the possibility of using prisms with twice as large angles between the working faces.

Electrostatically gated dissipation control in two-dimensional nanoelectromechanical resonators via strain-amplitude antagonism for record 928% Q tunability
Jiang Q., Fang J., Chen J. et al., Science China Information Sciences 2026 Vol. 69 No. 6 Article 162402
Resonators based on nanoelectromechanical systems (NEMS) using two-dimensional (2D) materials with high-quality factors and excellent electrical control are critical for tunable coherent phonon dynamics, resonant sensors and wireless communications. However, their performance is fundamentally limited by the lack of a unified framework governing energy dissipation mechanisms and their electrical tunability. Here, we synergistically modulate both ...

We present a new autocollimation method for measuring the refractive index (RI) of transparent triangular prisms. The classical autocollimation method is simple, but due to total internal reflection it is suitable only for prisms with small angles, which limits the accuracy of RI measurements. The proposed new method makes possible the autocollimation measurements of the RI for prisms with ...
