Scrape Off Layer (SOL) transport and filamentary characteristics in high density tokamak regimes

Holger Reimerdes, Benoît Labit, Christian Gabriel Theiler, Alexander Karpushov, Nicola Vianello, Cedric Kar-Wai Tsui, Kevin Henricus Annemarie Verhaegh, Roberto Maurizio, Wei Zhang, Hugo De Oliveira

A detailed cross-device investigation on the role of filamentary dynamics in high density regimes has been performed within the EUROfusion framework comparing ASDEX Upgrade (AUG) and TCV tokamaks. Both devices have run density ramp experiments at different ...

Large wind farms can destroy stratocumulus clouds-evidence from large eddy simulations.

Varun Sharma, Michael Lehning, Marc Parlange, Marc Calaf Bracons

Stratocumulus is one of the most common cloud types found in the atmospheric boundary layer (ABL) and have been shown to have a significant impact on modulating the global radiation and energy balance. In spite of their ubiquitousness however, their shallo ...

Molecular gas in two companion cluster galaxies at z=1.2

Gianluca Castignani, Anand Stéphane Raichoor

Context. Probing both star formation history and evolution of distant cluster galaxies is essential to evaluate the effect of dense environment on shaping the galaxy properties we observe today. Aims. We investigate the effect of cluster environment on the ...

Water soluble derivatives of platinum carbonyl Chini clusters: synthesis, molecular structures and cytotoxicity of [Pt-12(CO)(20)(PTA)(4)](2-) and [Pt-15(CO)(25)(PTA)(5)](2-)

Paul Joseph Dyson, Lucinda Kate Batchelor, Silvia Ruggieri

The reactions of Pt-3n(CO)(6n) (n = 2-5) homoleptic Chini-type clusters with increasing amounts of 1,3,5-triaza-7-phosphaadamantane (PTA) result in the stepwise substitution of one terminal CO ligand per Pt-3 triangular unit up to the formation of [P ...

Point Cloud Subjective Evaluation Methodology based on 2D Rendering

Touradj Ebrahimi, Evangelos Alexiou

Point clouds are one of the most promising technologies for 3D content representation. In this paper, we describe a study on quality assessment of point clouds, degraded by octree-based compression on different levels. The test contents were displayed usin ...
