An In-depth Analysis of Quiet-Sun IRIS Brightenings

The Astrophysical Journal
Small-scale brightenings are ubiquitous, dynamic, and energetic phenomena found in the chromosphere. An advanced filter-detection algorithm applied to high-resolution observations from the Interface Region Imaging Spectrograph enables the detection of ...

Conducting Luxury Research: Methodological Foundations and Standards

Psychology &Marketing, EarlyView.
ABSTRACT The field of luxury research has grown rapidly in recent years, corresponding to the economic importance of the luxury industry. Despite this, the luxury field lacks established methodological foundations for rigorous luxury research. This is particularly problematic as a core tenet of luxury research is that luxury differs from other sectors ...

Puzzling Variation of Gamma Rays from the Sun over the Solar Cycle Revealed with Fermi-LAT

The Astrophysical Journal Letters
The steady-state gamma-ray emission from the Sun is thought to consist of two emission components due to interactions with Galactic cosmic rays: (1) a hadronic disk component, and (2) a leptonic extended component peaking at the solar edge and extending ...

Theories of care help explain a peri‐urban tree diversity paradox

People and Nature, EarlyView.
Abstract Since diversity is often a management objective for peri‐urban tree communities on public land, one might expect to find greater diversity there than on private land, where such objectives are less common. However, this expectation rests on an assumption that people control diversity towards objectives, overlooking the role of relationships ...

Velocity and Density Fluctuations in the Quiet Sun Corona

The Astrophysical Journal
We investigate the properties and relationship between Doppler velocity fluctuations and intensity fluctuations in the off-limb quiet Sun corona. These are expected to reflect the properties of Alfvénic and compressive waves, respectively.

3D Simulations of the Quiet Sun Radio Emission at Millimeter and Submillimeter Wavelengths [PDF]

Geofísica Internacional, 2008
We present 2D projections of 3D simulations of the quiet-sun radio-emission, at different frequencies on the centimeter-submillimeter wavelength range (specifically at 1.4, 3.9, 17, 34, 43, 110, 212 and 250 GHz). We have built a 3D, spherically symmetric,

Synthesis and Characterization of an Azido Nitrofurazanyl Ether: An Energy‐Rich Heterocyclic Plasticizer With a Low Glass Transition Temperature

Propellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT We report on the synthesis and characterization of 3‐(2‐(2‐azidoethoxy)ethoxy)‐4‐nitro‐1,2,5‐oxadiazole (NFPEG2N3), which is a liquid nitrofurazanyl ether that was designed to be an energy‐rich plasticizer for glycidyl azide polymer (GAP)‐ and nitrocellulose (NC)‐based formulations.
