Thick Arnold tongues

Autor: Levi, Mark, Okunev, Alexey

We introduce and study a physically motivated problem that exhibits interesting and perhaps unexpected mathematical features. A cellular flow is a two-dimensional Hamiltonian flow of the Hamiltonian $H(x, y) = \cos(x) \cos(y)$. We study a simple mode

Spatiotemporally Consistent HDR Indoor Lighting Estimation

Autor: Li, Zhengqin, Yu, Li, Okunev, Mikhail, Chandraker, Manmohan, Dong, Zhao

We propose a physically-motivated deep learning framework to solve a general version of the challenging indoor lighting estimation problem. Given a single LDR image with a depth map, our method predicts spatially consistent lighting at any given imag

We present the study of the decay $J/\psi \rightarrow \rho\pi$. The results are based on of 5.2~million $J/\psi$ events collected by the KEDR detector at the VEPP-4M collider. The branching fractions are measured to be $\B(J/\psi \rightarrow \rho\pi)

Influence of carbon sorbents on the potential ability of soils to self-cleaning from petroleum pollution

Autor: E. V. Smirnova, R. V. Okunev, K. G. Giniyatullin

Publikováno v: Georesursy, Vol 24, Iss 3, Pp 210-218 (2024)

In a laboratory experiment, the ability of the soil to self-cleaning under heavy petroleum pollution and the effect of biochars and shungites on the cleaning process were studied. Incubation of contaminated soils for 28 days at a constant humidity an

Adapting to climate change: responses of fine root traits and C exudation in five tree species with different light-use strategy

Autor: Marili Sell, Gristin Rohula-Okunev, Priit Kupper, Ivika Ostonen

Publikováno v: Frontiers in Plant Science, Vol 15 (2024)

Trees that are categorised by their light requirements have similarities in their growth strategies and adaptation mechanisms. We aimed to understand the complex responses of elevated air humidity on whole tree fine root carbon (C) exudation (ExC) an
