Wildfires' Cost for Societal Welfare: Economic Evaluation of Forestry Ecosystem Services Losses in Southern Italy

Land Degradation &Development, EarlyView.
ABSTRACT Forest ecosystem services (ESs) are garnering increasing public attention as awareness grows regarding society's fundamental dependence on them for well‐being. Forest fires, one of the major disturbances of ESs, are becoming more frequent and destructive, exacerbated in part by climate change.

A Comprehensive Model of the K-coronal Spectrum for the Inference of Electron Temperature and Bulk Flow Velocity in the Corona

The Astrophysical Journal Supplement Series
The electron temperature of the corona is one of the key physical parameters which reflect the complexity of coronal-heating processes. L. E. Cram was the first to show that the K-coronal spectrum, produced by the scattering of the photospheric spectrum ...

Signatures for Solar Axions/WISPs

, 2010
Standard solar physics cannot account for the X-ray emission and other puzzles, the most striking example being the solar corona mystery. The corona temperature rise above the non-flaring magnetized sunspots, while the photosphere just underneath becomes

Periodic Variations in Visible Light Brightness as Tracers of Fine Coronal Structures

The Astrophysical Journal
The quiescent or dynamic nature of fine-scale raylike features in the Sun corona, observed in visible light, is still an open question. Here, we show that most of the daily and hourly periodic variations in visible light brightness of the high corona (up

Coronal Diagnostics from Narrowband Images around 30.4 nm

, 2012
Images taken in the band centered at 30.4 nm are routinely used to map the radiance of the He II Ly alpha line on the solar disk. That line is one of the strongest, if not the strongest, line in the EUV observed in the solar spectrum, and one of the few ...

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

Solar Stereoscopy and Tomography

Living Reviews in Solar Physics, 2011
We review stereoscopic and tomographic methods used in the solar corona, including ground-based and space-based measurements, using solar rotation or multiple spacecraft vantage points, in particular from the STEREO mission during 2007--2010 ...

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.

Structure and Dynamics of the Sun's Open Magnetic Field

, 2007
The solar magnetic field is the primary agent that drives solar activity and couples the Sun to the Heliosphere. Although the details of this coupling depend on the quantitative properties of the field, many important aspects of the corona - solar wind ...
