Temperature profile for glacial ice at the South Pole: Implications for life in a nearby subglacial lake

PB Price, OV Nagornov, R Bay… - Proceedings of the …, 2002 - National Acad Sciences
Airborne radar has detected ≈100 lakes under the Antarctic ice cap, the largest of which is
Lake Vostok. International planning is underway to search in Lake Vostok for microbial life …

Modeling of mechanisms of wave formation for COVID-19 epidemic

A Leonov, O Nagornov, S Tyuflin - Mathematics, 2022 - mdpi.com
Two modifications with variable coefficients of the well-known SEIR model for epidemic

Temperature reconstruction for Arctic glaciers

OV Nagornov, YV Konovalov, V Tchijov - Palaeogeography …, 2006 - Elsevier
Numerous data indicate discernible warming of the Northern Hemisphere in the 20th century
especially at high latitudes. Summer melting at the surface of Arctic glaciers is likely to …

Kink dynamics in a high-order field model

…, K Javidan, AA Malnev, OV Nagornov - arXiv preprint arXiv …, 2023 - arxiv.org
We study various properties of topological solitons (kinks) of a field-theoretic model with a
polynomial potential of the twelfth degree. This model is remarkable in that it has several …

Kinetics of phase transitions induced by shock-wave loading in ice

Experimental investigation of shock-wave loading of ice (Larson, DB J. Glaciol. 1984, 30,
235) indicates a series of phase transitions in ice and gives evidence of the important role the …

Spatially-distributed cyclotron oscillators approach to FT-ICR MS at the true cyclotron frequency: Computational evaluation of sensitivity

KO Nagornov, AN Kozhinov, YO Tsybin - International Journal of Mass …, 2021 - Elsevier
Routine Fourier transform ion cyclotron resonance mass spectrometry (FT- ICR MS) with ion
detection at the unreduced (true) cyclotron frequency, instead of the reduced cyclotron …

Reconstruction of past temperatures for Arctic glaciers subjected to intense subsurface melting

OV Nagornov, YV Konovalov, V Tchijov - Annals of Glaciology, 2005 - cambridge.org
Many glaciers are subject to melting due to high summer air temperatures. Here, the presence
of meltwater in the subsurface layers of the glacier bulk, and its subsequent percolation …

Fourier transform ion cyclotron resonance mass spectrometry at the true cyclotron frequency

KO Nagornov, OY Tsybin, E Nicol… - Mass spectrometry …, 2022 - Wiley Online Library
Ion cyclotron resonance (ICR) cells provide stability and coherence of ion oscillations in
crossed electric and magnetic fields over extended periods of time. Using the Fourier transform …

Prediction of thermodynamic state of the Gregoriev ice cap, Tien Shan, central Asia, in the future

O Nagornov, Y Konovalov, V Mikhalenko - Annals of Glaciology, 2006 - cambridge.org
We use a two-dimensional flowline model to study the flow of the Gregoriev ice cap, Tien
Shan, central Asia. The model takes into account the transverse change of glacier width, data …
