A group of researchers from the HSE Faculty of Computer Science and the Sber AI Lab has increased the speed of gradient boosting, one of the most efficient machine learning algorithms. The proposed approach will make it possible to solve classification and regression problems faster. The results of the work were presented at the NeurIPS conference.

An international team, including researchers of the HSE Faculty of Computer Science, has discovered a new mechanism of gene regulation in which microRNA assumes a central role. These non-coding molecules influence the DNA regions within genes that govern embryonic development. The study contributes to our understanding of the mechanisms underlying the diverse genetic programs found in complex multicellular organisms. The paper has been published in the International Journal of Molecular Sciences.

Researchers from HSE University’s Centre for Language and Brain, together with employees of Adyghe State University’s Laboratory of Experimental Linguistics, are conducting an expedition that is unprecedented in Russia: psycholinguistic field research into the Adyghe language and Russian-Adyghe bilingualism in a village in the Republic of Adygea.

Galina Shirokova, Professor at the Department of Management at HSE University-St Petersburg, has worked alongside international researchers to identify the role of social circles and cultural values in the success of young businesswomen. They found that support within a group increases the chances of women engaging in entrepreneurship.

A positive correlation has been discovered between the neural activity in the nucleus accumbens of study participants as they were presented with photographs of dishes from the menu of the Chaihona No. 1 restaurant chain and the sales performance of said dishes in the chain's establishments. This finding was made by a team of researchers of the HSE Institute for Cognitive Neuroscience, Lomonosov Moscow State University, and ETH Zurich (Switzerland). The study findings have been published in PLoS One.

This year, HSE University held the Mirror Laboratories project contest for the fourth time. A total of 19 applications were submitted to the contest from 16 HSE University research departments partnered with 16 organisations from 14 Russian regions. Following the contest results, 10 research projects received support.

An international team of scientists including a HSE researcher have detected a rare optical emission from one of the most powerful gamma-ray bursts in the history of observation. The team measured the parameters of the environment, from which the emission originated, and proceeded to construct a model that simulates the behaviour of gamma-ray bursts. This contributes to our understanding of why such bursts are accompanied by electromagnetic radiation in the visible range. The findings have been published in Nature Astronomy.

HSE scientists have discovered an association between individuals’ brain activity and the sales performance of a restaurant chain. A new neuroimaging study revealed a correlation between dopaminergic activity in the nucleus accumbens of participants as they were exposed to photos of dishes and the sales performance of said dishes. According to the researchers, examining the neural activity of a small group of individuals can aid restaurants in crafting more impactful menus and boosting their revenues. The paper has been published in Plos One.

Researchers from the MIEM HSE Centre for Quantum Metamaterials, jointly with colleagues from Germany and the UK, have proposed an algorithm for the automated compression of arbitrary environments (ACE). It opens up exciting new possibilities for the precise calculation of the dynamics of quantum systems. According to the scientists, the new method can assist in the design of quantum computers and novel communication systems. The study findings are published in Nature Physics.

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.
