Scientists Develop Algorithm for Accurate Financial Time Series Forecasting
Researchers at the HSE Faculty of Computer Science benchmarked more than 200,000 model configurations for predicting financial asset prices and realised volatility, showing that performance can be improved by filtering out noise at specific frequencies in advance. This technique increased accuracy in 65% of cases. The authors also developed their own algorithm, which achieves accuracy comparable to that of the best models while requiring less computational power. The study has been published in Applied Soft Computing.

(2R,3R)-1,4-Dioxaspiro[4.4]nonane-2,3-dicarboxylic and (2R, 3R)-1,4-dioxaspiro[4.5]decane-2,3-dicarboxylic acids

Acta Crystallographica Section E: Crystallographic Communications. 2018. Vol. 74. P. 1058–1062.
Ananyev I., Roitershtein D., Миняев М., Виноградов А., Нифантьев И.

The title compounds, C9H12O6 and C10H14O6, were formed by careful hydrolysis of the corresponding diethyl esters. Their single crystals were grown from an ethyl acetate/hexane mixture. Crystals of both compounds have monoclinic (P2(1)) symmetry with a single molecule in the asymmetric unit. Both crystal structures are very similar and display four -CO-OH center dot center dot center dot O=C(OH)-hydrogen bonds, forming a two-dimensional double-layered framework.

Diverse Interactions of Sterols with Amyloid Precursor Protein Transmembrane Domain Can Shift Distribution Between Alternative Amyloid-β Production Cascades in Manner Dependent on Local Lipid Environment
Volynsky P., Urban A., Pavlov K. et al., International Journal of Molecular Sciences 2025 Vol. 26 No. 2 Article 553
Alzheimer’s disease (AD) pathogenesis is correlated with the membrane content of various lipid species, including cholesterol, whose interactions with amyloid precursor protein (APP) have been extensively explored. Amyloid-β peptides triggering AD are products of APP cleavage by secretases, which differ depending on the APP and secretase location relative to ordered or disordered membrane microdomains. We used high-resolution NMR to probe ...
