HSE Researchers Learn to Determine the Level of Happiness of Russians by Posts in Social Networks
Researchers at the HSE Graduate School of Business have created a model for calculating the indicator of subjective well-being, based on the analysis of 7.2 million posts on the Odnoklassniki social network. They found that the lowest level of observed subjective well-being can be registered in the morning, and the highest can be found in the late evening. The results of the study were published in the Mathematics journal.
Only Left Hemisphere Involved in Action Naming
An international team including researchers from the HSE Centre for Language and Brain and the HSE Institute for Cognitive Neuroscience have demonstrated the critical role of the left, but not the right, inferior frontal gyrus in action naming. The study findings are published in Brain Structure and Function.
Machine Learning Predicts Epileptogenic Activity from High-Frequency Oscillation Rates
In an innovative study, researchers from HSE University, RAN Institute of Linguistics, and the National Medical and Surgical Centre named after N.I. Pirogov measured and analysed high-frequency oscillations (HFO) in different regions of the brain. An automated detector predicted seizure outcomes based on HFO rates with an accuracy rate of 85%, and by applying machine learning, made it possible to distinguish between epileptogenic and non-epileptogenic HFO. The study’s findings are published in Frontiers in Human Neurosciences.
Optimism Makes Algorithm for Reinforcement Learning More Effective
An international team of scientists from Russia, France and Germany (including researchers of the HSE Faculty of Computer Science, the HSE Artificial Intelligence Centre and the Artificial Intelligence Research Institute) have developed a new reinforcement learning algorithm (Bayes-UCBVI). This is the first Bayesian algorithm that has a mathematical proof of effectiveness and has been successfully tested in Atari games. The result was presented at the ICML-2022 conference.
Research Finds Genes Associated with Most Aggressive Kidney Cancer
HSE researchers have found genes characteristic of the most aggressive subtype of clear cell renal carcinoma. Having studied data on tumour samples from 456 patients, Grigory Puzanov, research fellow at the HSE Faculty of Computer Science International Laboratory of Bioinformatics, identified cancer subtypes associated with either a favourable or unfavourable course of the disease. The paper is published in Scientific Reports.
Study Explains Blood Donation Motivations
An international team of researchers from the HSE International Laboratory of Positive Psychology of Personality and Motivation, the Russian National Research Centre for Hematology, and a number of American universities examined the motivations of regular blood donors.
Microfluidic Chip Used to Test Drug Toxicity
A team including HSE researchers has developed a way to use microfluidic chips to assess the toxic effects of drugs on humans. This device will help identify and minimise the side effects of drugs during the preclinical trial stage and reduce the need for animal experiments. The study is published in Bulletin of Experimental Biology and Medicine.
Normal for the Abnormal: How the Image of a Maniac Appeared in Popular Culture
The image of a serial killer and/or rapist is a product of scientific discourse, transferred to the cinema, and then to TV series. In many films, the plot is based on finding and capturing such criminals by using a particular method — social and psychological profiling, and the appearance of a maniac in the cinema has been normalized today. Maria Marey, Senior Lecturer at HSE School of Philosophy and Cultural Studies, analysed how science and philosophy have contributed to the emergence of serial killer characters in popular culture, and how it affects the audience.
HSE Researchers Caused People to Behave Less Rationally by Suppressing Activity in Specific Parts of the Brain
Researchers at the HSE Institute for Cognitive Neuroscience have shown experimentally that magnetic stimulation of the prefrontal cortex of the brain causes test subjects to act less rationally, changing how they assess possible outcomes at the moment they make risky decisions. The scientists believe that the discovery will provide a better understanding of the mechanisms that give rise to gaming addiction. The results of the study were published in the journal Scientific Reports.
Senior Scholars’ High Achievements Rely on Strong Personality and Favourable Environment
According to researchers of the Moscow City Pedagogical University (MSPU) and HSE University Vladimir Postavnev, Irina Postavneva, Vadim Peskov and Alexey Dvoinin, certain personality traits can help older scholars stay productive and creative for a long time. The study findings are published in Acta Biomedica Scientifica.
