Nuclear 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 ...

Macro-estructuras de corrupción: el caso lava jato
Rivista di studi e ricerche sulla criminalità organizzata, 2018 In this article it is developed and analyzed a social network model of a criminal organization engaged on corruption in Brazil. The model, based on judicial records published by Brazilian authorities, is referenced herein as the “Lava Jato” network.

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 ...

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.

Physical Review E, 2009 A particle diffusing around a point of stable mechanical equilibrium in a static but non-conservative force field enters into a steady state characterized by circulation in the probability flux. Circulation in such a Brownian vortex is not simply a deterministic response to the solenoidal component of the force, but rather reflects an interplay between
