Scale-free Universal Spectrum for Atmospheric Aerosol Size Distribution for Davos, Mauna Loa and Izana [PDF]
, 2013 Atmospheric flows exhibit fractal fluctuations and inverse power law form for power spectra indicating an eddy continuum structure for the selfsimilar fluctuations. A general systems theory for fractal fluctuations developed by the author is based on the

Controlling Particulates and Dust in Vacuum Systems [PDF]
arXiv, 2020 Particulates and dust can limit accelerator performance in various ways. In this paper the basic properties and mechanisms of contaminations due to particulates are described. With this knowledge countermeasures can be implemented to minimize degradation due to particulates inside the accelerator vacuum systems.

Stand-off runaway electron beam termination by tungsten particulates for tokamak disruption mitigation [PDF]
arXiv, 2023 Stand-off runaway electron termination by injected tungsten particulates offers a plausible option in the toolbox of disruption mitigation. Tungsten is an attractive material choice for this application due to large electron stopping power and high melting point.

Characterizing rare fluctuations in soft particulate flows [PDF]
Nature Communications 8, No. 11 (2017), 2017 Soft particulate media include a wide range of systems involving athermal dissipative particles both in non-living and biological materials. Characterization of flows of particulate media is of great practical and theoretical importance. A fascinating feature of these systems is the existence of a critical rigidity transition in the dense regime ...
