HSE Researchers Make Aldehydes Perform Dual Function

Chemists from HSE University have discovered a way to carry out a reductive addition reaction without using an external reducing agent. Instead, the required 'resource' is supplied by the aldehyde itself, one of the reaction participants. This approach helps prevent unwanted side reactions, reduces toxicity, and simplifies the production and synthesis of organic molecules, including those used in the manufacture of medicines. The study has been published in Journal of Catalysis.

HSE Scientists Explain Why Findings in Autism Research Differ

Researchers from the Cognitive Health and Intelligence Centre at HSE University conducted the first-ever systematic review of studies on the specifics of emotion-from-motion perception in autism. The review showed that differences found between autistic and non-autistic individuals are largely associated with the experimental design and the types of tasks given to study participants. The review findings have been published in Research in Autism.

‘In Science, You Are Your Own Boss

Polina Nasledskova is interested in identifying gaps in linguistics and topics that have been overlooked by other researchers. In an interview for the Young Scientists of HSE University project, she spoke about rare ordinal numerals in Nakh-Daghestanian languages, the benefits of knitting for concentration, and the beauty of the Patriarshy Bridge.

A transmission system with a hybrid automatic repeat request is considered in the presence of slow Rayleigh fading. A technique is described for finding an upper estimation of the spectral efficiency for such a system with a restriction on the type of modulation. Estimation can be used in the analysis of developed and existing feedback transmission systems.

Об оценках сложности схем в одном бесконечном базисе

Podolskaya O., В кн.: Материалы IX молодежной научной школы по дискретной математике и ее приложениям (Москва, 16-21 сентября 2013 г.).: М.: Издательство ИПМ РАН, 2013. С. 97–100.

We study Boolean circuit complexity in an infinite basis consisting of all Boolean functions that equal 1 only on sets of pair-wise incomparable tuples. It is known that lower bounds on the complexity of linear function, majority function and almost all boolean functions of $n$ variables are of the order $\sqrt n.$ We show that ...
