Killing a Vortex

open access: yesJournal 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]

open access: yesJournal 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.

Vortex holography [PDF]

open access: yesNuclear Physics B, 2002
We show that the Abelian Higgs field equations in the four dimensional anti de Sitter spacetime have a vortex line solution. This solution, which has cylindrical symmetry in AdS$_4$, is a generalization of the flat spacetime Nielsen-Olesen string. We show that the vortex induces a deficit angle in the AdS$_4$ spacetime that is proportional to its mass ...

A Robust Vehicle Detection Model for LiDAR Sensor Using Simulation Data and Transfer Learning Methods

open access: yesAI, 2023
Vehicle detection in parking areas provides the spatial and temporal utilisation of parking spaces. Parking observations are typically performed manually, limiting the temporal resolution due to the high labour cost.

On the Contributions of the Northeast Cold Vortex to the Formation and Evolution of Backflow Blizzard

open access: yesFrontiers in Earth Science, 2022
Blizzard is a severe weather-related disaster with significant environmental, economic, and social impacts. What is worse, the blizzard is increasingly frequent along with climate change.

Detection of EGFR Mutations in cfDNA and CTCs, and Comparison to Tumor Tissue in Non-Small-Cell-Lung-Cancer (NSCLC) Patients

open access: yesFrontiers in Oncology, 2020
Lung cancer is the leading cause of cancer-related mortality worldwide. Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) therapies, based on the evaluation of EGFR mutations, have shown dramatic clinical benefits.

Method for Vortex Shape Retrieval and Area Calculation Based on Convex Hull Algorithm

open access: yesIEEE Access, 2021
The shape and area of the vortex are important indicators to judge the effect of chemical liquid spraying and crop pollination by agricultural plant protection UAV. However, the traditional way of extracting the vortex related data through manual methods
