Non-Kolmogorov turbulence in carotid artery stenosis and the impact of carotid stenting on near-wall turbulence

AIP Advances, 2022
Endovascular stents have become a standard management procedure for carotid artery stenosis. Recent discoveries related to the complex turbulence dynamics in blood flow necessitate revisiting the pathology of carotid stenosis itself and the impact of ...

Propagation of a Lorentz Non-Uniformly Correlated Beam in a Turbulent Ocean

Photonics, 2023
We study the propagation characteristics (spectral intensity and degree of coherence) of a new type of Lorentz non-uniformly correlated (LNUC) beam based on the extended Huygens–Fresnel principle and the spatial power spectrum of oceanic turbulence.

The Small-Scale Dynamo and Non-Ideal MHD in Primordial Star Formation [PDF]

, 2012
We study the amplification of magnetic fields during the formation of primordial halos. The turbulence generated by gravitational infall motions during the formation of the first stars and galaxies can amplify magnetic fields very efficiently and on ...

Multifractal structure of turbulence in the magnetospheric cusp [PDF]

Annales Geophysicae, 2004
Magnetospheric cusps are regions which are characterized by highly turbulent plasma. We have used Polar magnetic field data to study the structure of turbulence in the cusp region. The wavelet transform modulus maxima method (WTMM) has been applied to

Supernova neutrinos and the turbulence power spectrum: point source statistics

, 2015
The neutrinos emitted from the proto-neutron star created in a core-collapse supernova must run through a significant amount of turbulence before exiting the star.

Change in the state of polarization of Gaussian Schell-model beam propagating through non-Kolmogorov turbulence

Results in Physics, 2017
Analysis of effect of source parameters and the turbulence on the state of polarization of Gaussian Schell-model beam (GSM) is carried out based on the non-Kolmogorov power spectrum.

Universality and intermittency in relativistic turbulent flows of a hot plasma

, 2013
With the aim of determining the statistical properties of relativistic turbulence and unveiling novel and non-classical features, we resent the results of direct numerical simulations of driven turbulence in an ultrarelativistic hot plasma using high ...
