Understanding the Variability of Helium Abundance in the Solar Corona Using Three-fluid Modeling and Ultraviolet Observations

The Astrophysical Journal Letters
The variability of helium abundance in the solar corona and the solar wind is an important signature of solar activity, solar cycle, and solar wind sources, as well as coronal heating processes.

Degradation of Crystalline Si‐Based Solar Modules With Varying Material Combinations—Part I: Encapsulant Degradation

Progress in Photovoltaics: Research and Applications, EarlyView.
This work deals with the degradation of solar modules with varying material combinations under accelerated aging conditions. By in situ moisture measurements and simulations of oxygen ingress, the consumption of stabilizing additives and polymer degradation can be correlated spatially resolved with the penetrating stressors.

The possible role of vortex shedding in the excitation of kink-mode oscillations in the solar corona [PDF]

, 2009
We propose a model for the excitation of horizontally polarised transverse (kink) magnetoacoustic oscillations of solar coronal loops by upflows associated with coronal mass ejections.

Investigating Alfvénic wave propagation in coronal open-field regions [PDF]

, 2015
The physical mechanisms behind accelerating solar and stellar winds are a long-standing astrophysical mystery, although recent breakthroughs have come from models invoking the turbulent dissipation of Alfvén waves.

Embedded Interactions and Selective Disclosure: Network Effects on Conversations aboard Skylab

Symbolic Interaction, EarlyView.
How do absent others influence our interactions? We argue in this paper that interactions are embedded within networks formed by chains of specific relationships between known third parties. The anticipation of future interactions with external others conditions our interpretation of the current situation and affects our behavior in the interaction. We
