Development and Validation of the Whole Atmosphere Community Climate Model With Thermosphere and Ionosphere Extension (WACCM‐X 2.0)

Journal of Advances in Modeling Earth Systems, Volume 10, Issue 2, Page 381-402, February 2018., 2018
Abstract Key developments have been made to the NCAR Whole Atmosphere Community Climate Model with thermosphere and ionosphere extension (WACCM‐X). Among them, the most important are the self‐consistent solution of global electrodynamics, and transport of O+ in the F‐region.

Emerging technologies for high performance infrared detectors

Nanophotonics, Volume 7, Issue 1, Page 169-197, January 2018., 2018
Abstract Infrared photodetectors (IRPDs) have become important devices in various applications such as night vision, military missile tracking, medical imaging, industry defect imaging, environmental sensing, and exoplanet exploration. Mature semiconductor technologies such as mercury cadmium telluride and III–V material‐based photodetectors have been ...

Statistical Analysis of Machine Learning‐Derived Equatorial Plasma Bubble Characteristics From Airglow Observations in Southern China During a Solar Cycle

Space Weather, Volume 23, Issue 11, November 2025.
Abstract The equatorial plasma bubble (EPB) evolutionary behavior in the Chinese sector remains poorly understood due to insufficient long‐term statistical characterization. Leveraging prior machine learning frameworks, this work presents the first statistical profile of EPB evolution over an entire solar cycle (2012–2022) in southern China, using ...

Cosmic Rays Report from the Structure of Space

Advances in Astronomy, Volume 2015, Issue 1, 2015., 2015
Spectrum of cosmic rays follows a broken power law over twelve orders of magnitude. Since ubiquitous power laws are manifestations of the principle of least action, we interpret the spectrum accordingly. Our analysis complies with understanding that low‐energy particles originate mostly from rapidly receding sources throughout the cosmos.

Circular polarization as a probe of cloud properties and asymmetries in giant exoplanet atmospheres

Astronomy & Astrophysics
Context. Polarimetry is a promising method for characterizing clouds in exoplanetary atmospheres. For planets in the Solar System, circular polarization measurements complement linear polarimetry by providing additional information on cloud particle ...

Vision at high latitudes: High sensitivity without specific boreal adaptations in photoreception in reindeer (Rangifer tarandus L.)

Functional Ecology, Volume 39, Issue 10, Page 2573-2587, October 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The light climate at high latitudes, in particular the extended twilight of winter and the reduced diel variation in light level in midsummer and midwinter, potentially constrains visual function and the synchronisation of temporal organisation in polar species. In this

Anomalous Microwave Emission from Star Forming Regions

Advances in Astronomy, Volume 2013, Issue 1, 2013., 2013
The evidence for microwave emission from spinning dust grains has been strengthened considerably by its detection in a number of discrete astrophysical objects associated with star formation. These detections, in combination with statistical constraints on its presence on large angular scales in the diffuse ISM, have provided strong observational ...

At the edge of darkness: A framework for the evolution of visual systems in dim light

Functional Ecology, Volume 39, Issue 10, Page 2626-2636, October 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Light is an important biological cue for all living things. For animals, where many behaviours are driven by sensory input from the eyes, light is also a critical environmental feature shaping animal eye evolution, with the intensity of light (i.e.

Spinning Dust Emission from Wobbling Grains: Important Physical Effects and Implications

Advances in Astronomy, Volume 2012, Issue 1, 2012., 2012
We review the major progress on the modeling of electric dipole emission from rapidly spinning tiny dust grains, including polycyclic aromatic hydrocarbons (PAHs). We begin by summarizing the original model of spinning dust proposed by Draine and Lazarian and recent theoretical results improving the Draine and Lazarian model.

Three-dimensional B-fields in the Interstellar Medium and Star-forming Regions (3D-BLISS). I. Using Starlight Polarization in the Massive IRDC Filament G11.11-0.12

The Astrophysical Journal
Measuring three-dimensional magnetic fields (3D B -fields) is essential to understanding the formation and evolution of the interstellar medium and multiscale star formation; however, the accurate measurement of 3D B -fields is still challenging.
