Application of a satellite-retrieved sheltering parameterization (v1.0) for dust event simulation with WRF-Chem v4.1 [PDF]

open access: yesGeoscientific Model Development, 2023
Roughness features (e.g., rocks, vegetation, furrows) that shelter or attenuate wind flow over the soil surface can considerably affect the magnitude and spatial distribution of sediment transport in active aeolian environments.

Foreign “Predation” and Commercial Resources Protection in Far East of Russia (Late 19th - Early 20th Centuries)

open access: yesНаучный диалог, 2019
The problem of foreign “predation” (poaching) in the Far East of Russia in the late 19th - early 20th centuries is considered. Attention is paid to the activities of the Russian authorities (both local and central) to counter foreign poaching in the Far ...

Center Regions as a Solution to the Gribov Problem of the Center Vortex Model [PDF]

open access: yesActa Physica Polonica B Proceedings Supplement, 2021
The center vortex model, capable of explaining confinement and chiral symmetry breaking, has been plagued by the lattice equivalent of Gribov copies: different maxima of the gauge functional lead to different predictions of the string tension. It is possible to resolve this problem using center regions, loops evaluating to center elements, as guide for

Ice-rich slurries can account for the remarkably low friction of ice skates

open access: yesJournal of Glaciology, 2023
Ice skates are remarkably slippery across a wide range of conditions. We propose, based on earlier observations and new modeling, that an ice-rich slurry forms rapidly beneath a skate blade during each stride to lubricate the interface.

Improving Center Vortex Detection by Usage of Center Regions as Guidance for the Direct Maximal Center Gauge

open access: yes, 2019
The center vortex model of quantum chromodynamic states that vortices, a closed color-magnetic flux, percolate the vacuum. Vortices are seen as the relevant excitations of the vacuum, causing confinement and dynamical chiral symmetry breaking.
