Road Injuries Leading Cause of Death Among Men Aged 10 to 39
Worldwide, road injuries are the leading cause of death among males aged 10–39. An international team of researchers reached this conclusion as part of the Global Burden of Disease Study 2023, analysing data from 204 countries between 1990 and 2023. Their findings have been published in The Lancet Public Health, with HSE University Professor Vasily Vlassov listed among the collaborators.

‘Our Team Consists of True Leaders in Their Respective Academic Disciplines
The HSE International Centre of Decision Choice and Analysis studies a wide range of methods for analysing decision-making and possible scenarios for the development of natural, socio-economic, and political phenomena using various mathematical models. The application of advanced mathematical methods to forecasting helps to prevent negative outcomes and avoid erroneous decisions. The HSE News Service spoke to the centre’s director, Prof. Fuad Aleskerov, about its work.

Novel Signal-Code Construction for Multiple Access System over Vector-Disjunctive Channel

Ch. 1. P. 560–564.
Ivanov F., Rybin P.

We consider a new signal-code construction for a special class of multiple access system over vector-disjunctive channel when users transmit some vector of bits of finite length L. We propose a special encoding and decoding algorithms for such transmission scenario. Our suggested methods of encoding and decoding on one hand have acceptable complexity for a wide range parameters and on other one a decoding rule we considered has a performance very close to maximum likelihood (ML) decoding. We present some simulation results for relative sum-rate of our construction and for frame error rate (FER) in the case of different number of active users and different code constructions. Simulation results we obtained allow us to conclude that our scheme has a good performance even for very short codes.

Non-orthogonal multiple access schemes are of great interest for next generation wireless systems, as such schemes allow to reduce the total number of resources (frequencies or time slots) in comparison to orthogonal transmission (TDMA, FDMA, CDMA). In this paper we consider an iterative LDPC-based joint decoding scheme suggested in [1]. We investigate the most difficult ...
