A mathematical model has helped describe the course of infection caused by two variants of coronavirus: Omicron and Delta, and explain the differences between them. It appears that the cell entry rate is lower for Omicron, allowing infected cells ample time to alert neighbouring cells of the threat and trigger the activation of their innate immune response. In the future, the developed model could be employed to investigate any other variant of COVID-19, potentially leading to effective strategies for combating new hazardous strains, such as Pirola and JN.1. The findings from the study conducted with the participation of HSE researchers have been published in PeerJ.

Scientists of the International Laboratory of Dynamic Systems and Applications at HSE Campus in Nizhny Novgorod have described a rare case of synchronisation in a system of chemically coupled neuron models. The study findings enable a mathematical description of atypical brain functioning modes, including those associated with neurodegenerative diseases. The study has been published in Regular and Chaotic Dynamics.

For Elena Nozdrinova, mathematics is her life's work and a realm where she discovers universal order and harmony. In her interview with the HSE Young Scientists project, she speaks about dynamical systems, the Nizhny Novgorod scientific school, and favourite pastimes that help her grow.

Researchers from the International Laboratory of Dynamical Systems and Applications at the HSE Campus in Nizhny Novgorod have discovered that the use of systems with hyperbolic solenoid attractors and repellers can lead to issues in the transmission of communication signals. The findings of this study have been published in Results in Mathematics. The research was financed by a substantial grant from the Russian Government as part of the 'Science and Universities' National Project and a further grant from the Russian Science Foundation.

Rogue waves, or killer waves, are abnormally high and deadly waves that can emerge unpredictably in open seas and along shorelines. They pose an imminent deadly threat to everyone from colossal liners and pleasure yachts to seafarers and vacationers. Scientists from the HSE campus in Nizhny Novgorod Efim Pelinovsky and Ekaterina Didenkulova have assembled a catalogue of such phenomena that occurred in the World Ocean from 2011 to 2018, identifying the areas where they are frequently documented and inflict the most substantial damage.

The speakers of the International Congress of Mathematicians, a key global mathematics event held every four years by the International Mathematical Union, have been announced. The next ICM will take place in St. Petersburg, Russia, in July 2022. Five researchers from the HSE Faculty of Mathematics will present their papers at the congress.
