Timur Khusyainov, Deputy Dean of theFaculty of Humanities atHSE University–Nizhny Novgorod, took part in two international conferences—the XVI World Congress of Rural Sociology in Porto Alegre, Brazil, and the 36th Annual Conference of the Alliance of Digital Humanities Organisations (DH2026) in Daejeon, South Korea. On his way to the conferences, the researcher also visited several other places, where he presented the experience of the Pochtovoe educational project.
Large vortices with characteristic spiral arms are often observed in the atmosphere and the ocean. Physicists from HSE University have explained how these structures form and why they retain their shape. The researchers found that velocities at points located along the same vortex arc remain correlated even over long distances. At the same time, this correlation weakens rapidly with increasing distance from the vortex centre. These differences help explain the formation of spiral arms and may improve models of atmospheric and oceanic currents. The findings have been published in Physical Review Fluids.
Anastasia Gergenreter specialises in applied statistics and econometrics. In this interview for the Young Scientists of HSE University project, she talked about why she studies addictive substance use, two very different Fishers, and the cherry blossom season at the Main Botanical Garden in Moscow.

In the linear approximation is carried out numerical simulation and analysis of the features of the interaction of colliding electron beams in a drift tube with the reduction ratio of plasma oscillations and electronic interaction between threads. In the hydrodynamic approach in the weak signal wave technique developed theories related to space-charge waves colliding electron ...

The finitedifference theory of excitation of periodic waveguides is used to derive the characteris tic equation for electron waves formed during interaction of an electron beam with forward and counter propagating electromagnetic waves of periodic waveguides (slowwave structures). The derived characteristic equation describes interaction of electrons and waves in passbands and stopbands of periodic waveguides ...
