Valence and diffuse-bound anions of noble-gas complexes with uracil 

Streit, Livia; Dolgounitcheva, O.; Zakrzewski, V. G.; Ortiz, J. V.; Ortiz, Joseph Vincent (2020-08-20)
Valence-bound (VB) and diffuse-bound (DB) anions of noble-gas (Ar, Kr, and Xe) complexes with uracil have been studied with ab initio methods. MP2 optimizations revealed minima corresponding to anions of both kinds in ...

Variation of Morphology and Elemental Concentrations in the California Nickel Hyperaccumulator Streptanthus polygaloides (Brassicaceae) 

Boyd, Robert S.; Wall, Michael A.; Santos, Scott R.; Davis, Michael A. (2021-01-04)
The Ni hyperaccumulator Strepthanthus polygaloides (Brassicaceae) is one of a handful of Ni hyperaccumulators known from continental North America. Surveys have revealed four distinctive morphs of this species, relying ...

VHF and UHF Electromagnetic Radiation Produced by Streamers in Lightning 

Shi, Feng; Dwyer, Joseph R.; Ihaddadene, Kevin M.A.; Liu, Ningyu; https://orcid.org/0000-0003-3406-9383 (2020-03-10)
In this letter, we report simulation results of streamer propagation and collision that produce electromagnetic radiation in the very high frequency (VHF) and ultra high frequency (UHF) bands. The streamers are initiated ...

Visitors to Southeastern Hawkmoth Flowers 

Graham, Sean P. (2022-07-29)
- Despite global concern for the status of animal pollinators, studies on pollination systems in the southeastern United States are disproportionately low compared to the diversity of this region. For example, sphingophilous, ...

The Vitamin A-Redox Hypothesis: A Biochemical Basis for Honest Signaling via Carotenoid Pigmentation 

Hill, Geoffrey; Johnson, James D; 0000-0001-8864-6495 (2022-07-29)
Trade-offs in resource allocation have been widely stated as the means by which the honesty of ornamental traits is maintained, but an alternative to this resource trade-off hypothesis is that production of ornamentation ...

Wave Normal Angle Distribution of Magnetosonic Waves in the Earth's Magnetosphere: 2-D PIC Simulation 

Sun, Jicheng; Chen, Lunjin; Wang, Xueyi; 0000-0002-5059-5394; 0000-0003-2489-3571 (2022-10-11)
Radiation belt electrons can be accelerated and scattered by magnetosonic waves in the Earth's magnetosphere, and the scattering rate of electrons is sensitive to the wave normal angle. However, observationally it is ...

Whistler anisotropy instabilities as the source of banded chorus: Van Allen Probes observations and particle-in-cell simulations 

Fu, Xiangrong; Liu, Kaijun; Min, Kyungguk; Winske, Dan; 0000-0001-5882-1328; 0000-0002-2095-8529 (2020-06-05)
Magnetospheric banded chorus is enhanced whistler waves with frequencies (r)<(e), where (e) is the electron cyclotron frequency, and a characteristic spectral gap at (r)similar or equal to(e)/2. This paper uses spacecraft ...

Fu, Xiangrong; Cowee, Misa; Friedel, Reinhard; Funsten, Herbert; Gary, S; Hospodarsky, George; Kletzing, Craig; Kurth, William; Larsen, Brian; Liu, Kaijun; MacDonald, Elizabeth; Min, Kyungguk; Reeves, Geoffrey; Skoug, Ruth; Winske, Dan; 0000-0003-3117-4030; 0000-0002-7985-8098; 0000-0002-6817-1039; 0000-0002-5228-0281; 0000-0003-4515-0208; 0000-0001-5882-1328; 0000-0003-3117-4030; 0000-0002-5471-6202; 0000-0001-5882-1328; 0000-0002-4305-6624; 0000-0001-9200-9878; 0000-0002-4136-3348; 0000-0003-1991-2643 (2023-01-25)
Magnetospheric banded chorus is enhanced whistler waves with frequencies (r)<(e), where (e) is the electron cyclotron frequency, and a characteristic spectral gap at (r)similar or equal to(e)/2. This paper uses spacecraft ...

Whistler Mode Waves Excited by Anisotropic Hot Electrons With a Drift Velocity in Earth's Magnetosphere: Linear Theory 

Kai, Fan; Jicheng, Sun; Jun, Guo; 0000-0002-5059-5394 (2022-11-08)
With a linear theoretical model, we have investigated the properties of whistler waves excited by anisotropic hot electrons with a drift velocity parallel to the background magnetic field, which is usually neglected in ...

Why are incubation periods longer in the tropics? A common-garden experiment with house wrens reveals it is all in the egg 

Robinson, Douglas; Styrsky, John; Payne, Brian; Harper, Given; Thompson, Charles; 0000-0003-2240-0606 (2023-05-17)
Incubation periods of Neotropical birds are often longer than those of related species at temperate latitudes. We conducted a common-garden experiment to test the hypothesis that longer tropical incubation periods result ...
