‘Hedgehog Versus ‘Relatives: Researchers Measure How the Brain Responds to Unexpected Words During Natural Speech
Russian neurophysiologists, including researchers from HSE University, have demonstrated the feasibility of using event-related fields (ERFs) to study brain activity during natural speech perception. The researchers showed that this approach can be applied not only to individual words but also to continuous speech. Their findings indicate that words whose meanings differ significantly from the preceding context require longer processing times. The study also reveals that the brain processes function words in two stages: first, it identifies their grammatical role and then uses this information to predict the next word. The study has been published in Frontiers in Human Neuroscience.

Scientists Develop Algorithm for More Reliable Processors in Data Centres
Researchers from HSE MIEM and Samara University have developed the LRF-3D algorithm to automatically bypass idle nodes in three-dimensional networks-on-chip. Thanks to its hierarchical architecture, the algorithm outperforms existing solutions in both speed and path accuracy, improving processor reliability for use in data centres, supercomputers, and AI computing. The source code and test results are publicly available.

DEA for Heterogeneous Samples

P. 15–21.
Aleskerov F. T., Petrushchenko S.

Data Envelopment Analysis is not very well applicable when a sample consists of firms operating under drastically different conditions. We offer a new method of efficiency estimation on heterogeneous samples based on a sequential exclusion of alternatives and standard DEA approach. We show a connection between efficiency scores obtained via standard DEA model and the ones obtained via our algorithm. We also illustrate our model by evaluating 28 Russian universities and compare the results obtained by two techniques.

Transitivity in Pairwise Comparisons and the Heterogeneity of Psychological Attributes
Yulia Tyumeneva, Sudorgina Y., Basic and Applied Social Psychology 2024 Vol. 46 No. 5 P. 314–320
Likert scales rely on the assumption that psychological attributes are ordinal, meaning that the attribute levels a, b, and c are in transitive relations. Testing transitivity is possible through pairwise comparisons of attribute levels. Previous tests showed that people can violate transitivity, which calls into question the basic assumption of rating scales. We hypothesized that ...

Secret reserve prices by uninformed sellers

If bidders are better informed than the seller about a common component of auction heterogeneity, the seller can allocate more efficiently by keeping her reserve price secret and revising it using submitted bids. We build a model of a first-price auction under unobserved auction heterogeneity—imperfectly observed by the seller—that captures this rationale and derive conditions ...
