Journal of the ACM, 2022 The Graph Minors Structure Theorem of Robertson and Seymour asserts that, for every graph H , every H -minor-free graph can be obtained by clique-sums of “almost embeddable” graphs. Here a graph is “almost embeddable” if it can be obtained from a graph of bounded Euler-genus by pasting graphs

Definitions of vortex vector and vortex [PDF]
Journal of Fluid Mechanics, 2018 Although the vortex is ubiquitous in nature, its definition is somewhat ambiguous in the field of fluid dynamics. In this absence of a rigorous mathematical definition, considerable confusion appears to exist in visualizing and understanding the coherent vortical structures in turbulence.

Liutex-Represented Vortex Spectrum in Turbulence
Entropy, 2022 The Liutex vector is new quantity introduced to represent the rigid-body rotation part of fluid motion and thus to define and identify vortices in various flows. In this work, the intermittency and power-law similarity of the Liutex vector in homogeneous,

WRF-LES Simulation of the Boundary Layer Turbulent Processes during the BLLAST Campaign
Atmosphere, 2020 A real case long-term nested large eddy simulation (LES) of 25-day duration is performed using the WRF-LES modelling system, with a maximum horizontal grid resolution of 111 m, in order to explore the ability of the model to reproduce the turbulence ...
