Synthesis of 3-D coronal-solar wind energetic particle acceleration modules [PDF]

open access: yes, 2014
1. Introduction Acute space radiation hazards pose one of the most serious risks to future human and robotic exploration. Large solar energetic particle (SEP) events are dangerous to astronauts and equipment.

Radio Interference Prediction Method for EHV AC Transmission Lines at High Altitudes Based on Long‐Term Observations

open access: yesHigh Voltage, EarlyView.
ABSTRACT Radio interference (RI) is a critical factor in the design of extra‐high voltage (EHV) transmission lines at high altitudes. To address the insufficient field data of RI on high‐altitude transmission lines, the lack of adequate validation for existing RI prediction methods, and the difficulty in assessing RI levels under various meteorological

The International Guideline for the Definition, Classification, Diagnosis and Management of Urticaria

open access: yesAllergy, EarlyView.
ABSTRACT This update and revision of the international guideline for urticaria was developed in accordance with the methods recommended by Cochrane and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) working group. It is an initiative of the Global Allergy and Asthma Excellence Network (GA2LEN) and its Urticaria and ...

On the Origin of the Dominant Waves in the Extended Solar Corona

open access: yesThe Astrophysical Journal
The extended solar corona at 10–30 solar radii is essentially devoid of all waves below 100 kHz other than triggered ion acoustic waves (TIAWs), which consist of a low-frequency (LF) electromagnetic wave at a frequency of a few Hz coupled to one or more ...

New views on the emission and structure of the solar transition region

open access: yes, 2010
The Sun is the only star that we can spatially resolve and it can be regarded as a fundamental plasma laboratory of astrophysics. The solar transition region (TR), the layer between the solar chromosphere and corona, plays an important role in solar wind

Long-period intensity pulsations in the solar corona during activity cycle 23 [PDF]

open access: yesAstronomy & Astrophysics, 2014
We report on the detection (10 ) of 917 events of long-period (3 to 16 hours) intensity pulsations in the 19.5 nm passband of the SOHO Extreme ultraviolet Imaging Telescope. The data set spans from January 1997 to July 2010, i.e the entire solar cycle 23 and the beginning of cycle 24.

Observational Test of Coronal Magnetic Field Models I. Comparison with Potential Field Model

open access: yes, 2008
Recent advances have made it possible to obtain two-dimensional line-of-sight magnetic field maps of the solar corona from spectropolarimetric observations of the Fe XIII 1075 nm forbidden coronal emission line.

Observation of coronal loop torsional oscillation [PDF]

open access: yes, 2003
We suggest that the global torsional oscillation of solar coronal loop may be observed by the periodical variation of a spectral line width. The amplitude of the variation must be maximal at the velocity antinodes and minimal at the nodes of the ...

Understanding the Evidence Gaps: Diets and Fruit and Vegetable Intake Across Five Diverse Low‐ and Middle‐Income Countries

open access: yesMaternal &Child Nutrition, EarlyView.
This perspective article synthesizes findings from scoping reviews examining diet and F&V intake, and interventions to increase F&V consumption among population groups in five countries: Benin, Fiji, the Philippines, Sri Lanka and Tanzania. ABSTRACT Poor dietary quality, particularly inadequate fruit and vegetable (F&V) intake, remains a significant ...

Nonlinear Fast Magnetosonic Waves in Solar Prominence Pillars

open access: yesThe Astrophysical Journal, 2023
We investigate the properties of nonlinear fast magnetosonic (NFM) waves in a solar prominence, motivated by recent high-resolution and high-cadence Hinode/Solar Optical Telescope (SOT) observations of small-scale oscillations in a prominence pillar.
