ALK1 controls hepatic vessel formation, angiodiversity, and angiocrine functions in hereditary hemorrhagic telangiectasia of the liver

open access: yesHepatology, EarlyView., 2022
Hepatic endothelial Alk1 signaling protects from development of vascular malformations while maintaining organ‐specific endothelial differentiation and angiocrine portmanteau of the names Wingless and Int‐1 signaling. Abstract Background and Aims In hereditary hemorrhagic telangiectasia (HHT), severe liver vascular malformations are associated with ...

Turbulent dynamo in a collisionless plasma [PDF]

open access: yesProceedings of the National Academy of Sciences, 2016
Significance Although magnetic field amplification by a dynamo effect converting kinetic flow energy into magnetic energy has long been shown in conventional magnetohydrodynamic fluids, whether a similar effect is possible in more dynamically complex weakly collisional plasmas, such as those encountered in astrophysical objects on ...

Electron and Ion Energization in Relativistic Plasma Turbulence. [PDF]

open access: yesPhysical Review Letters, 2018
Electron and ion energization (i.e., heating and nonthermal acceleration) is a fundamental, but poorly understood, outcome of plasma turbulence. In this work, we present new results on this topic from particle-in-cell simulations of driven turbulence in ...

Cascades and Dissipative Anomalies in Nearly Collisionless Plasma Turbulence [PDF]

open access: yesPhysical Review X, 2018
We develop first-principles theory of kinetic plasma turbulence governed by the Vlasov-Maxwell-Landau equations in the limit of vanishing collision rates.

On the spectrum of mid-latitude sporadic-E irregularities [PDF]

open access: yesAnnales Geophysicae, 2000
We discuss the creation of mid-latitude sporadic-E plasma irregularities (with length-scales smaller than sporadic layer thickness) by the neutral atmosphere turbulence.

The Impact of Turbulence on the Ionosphere and Magnetosphere

open access: yesFrontiers in Astronomy and Space Sciences, 2021
An important property associated with turbulence in plasmas and fluids is anomalous transport. Plasma, being a good conductor, can in addition be affected by turbulence causing an anomalous resistivity that can significantly exceed its classical ...

Turbulence, spatial transport, and heating of the solar wind [PDF]

open access: yes, 1999
A phenomenological theory describes radial evolution of plasma turbulence in the solar wind from 1 to 50 astronomical units. The theory includes a simple closure for local anisotropic magnetohydrodynamic turbulence, spatial transport, and driving by ...

Particle Acceleration in Relativistic Plasma Turbulence. [PDF]

open access: yesPhysical Review Letters, 2018
Due to its ubiquitous presence, turbulence is often invoked to explain the origin of nonthermal particles in astrophysical sources of high-energy emission.

α Effect and Magnetic Diffusivity β in Helical Plasma Under Turbulence Growth

open access: yesUniverse
We investigate the transport coefficients α and β in plasma systems with varying Reynolds numbers while maintaining a unit magnetic Prandtl number (PrM). The α and β tensors parameterize the turbulent electromotive force (EMF) in terms of the large-scale

Shadowing effects in simulated Alcator C-Mod gas puff imaging data

open access: yesNuclear Materials and Energy, 2019
A synthetic gas puff imaging (GPI) diagnostic is applied to a gyrokinetic turbulence simulation of Alcator C-Mod with the objective of assessing the impact of turbulent plasma fluctuations on the GPI neutral density field.
