‘In the Age of Technology, It Is Interesting to Look into the Past and Think about What We Can Take from It
Polina Tabakova decided to apply for a Philology degree at HSE in Nizhny Novgorod because she grew up in Mari El and did not want to move far away from the Russian forests. In an interview for the Young Scientists of HSE University project, she spoke about the genre of the campus novel, the existential drama of Kolobok, and a blackout version of Eugene Onegin.

HSE Scientists Develop Method to Compress Large Language Models Without Losing Quality
Researchers from the AI and Digital Science Institute at the HSE Faculty of Computer Science have developed a new compression method for large language models such as GPT and LLaMA that reduces their size by 25–36% without additional training or significant loss of accuracy. This is the first approach to use mathematical transformations—specifically, rotations of model weights—to make models more amenable to compression with structured matrices. The study results have been published in ACL Findings 2025. The code is available on GitHub.

Cyclopentadienyl lanthanide borohydrides derived from the unsubstituted cyclopentadienyl ligand. Unprecedented structural diversity and ε-caprolactone polymerization

Inorganica Chimica Acta. 2022. Vol. 529. Article 120638.
Bardonov D., Komarov P., Sadrtdinova G., Besprozvannyh V., Lyssenko K., Gudovannyi A., Nifant'ev I., Minyaev M., Roitershtein D.

A series of mono-, bis and tris(cyclopentadienyl) complexes of La, Nd and Tb with borohydride ligands were synthesized and structurally characterized. Various structural types of complex anions and cations containing cyclopentadienyl and borohydride ligands in the coordination sphere of Ln3+ have been studied by single-crystal X-ray diffraction. Five different structural types of Cp-lanthanide borohydrides were found for neodymium: {CpNd(BH4)2} in [(CpNd(BH4)2(THF)2] (2Nd); {Cp2Nd(BH4)2}- in [Cp2Nd(BH4)2][Na(18-crown-6)(THF)2] (3Nd); {Cp2Nd(BH4)} in [Cp2Nd(BH4)(THF)] (4Nd); {CpNd(18-crown-6)(BH4)}+ in [Cp2Nd(BH4)2]2[CpNd(18-crown-6)(BH4)][Na(18-crown-6)(THF)2] (6Nd); {Cp3Nd(BH4)}- in [Cp3Nd(BH4)][Na(18-crown-6)(THF)2] (8Nd). Complex anions {Cp2Nd(BH4)2}- and {Cp3Nd(BH4)}- are able to replace each other in the crystal lattice. Mono- and bis(cyclopentadienyl)borohydride complexes of neodymium effectively initiate ε-caprolactone polymerization.
