Hall effect control of magnetotail dawn-dusk asymmetry: A three-dimensional global hybrid simulation
(2020-06-03)
Magnetotail reconnection and related phenomena (e.g., flux ropes, dipolarizing flux bundles, flow bursts, and particle injections) occur more frequently on the duskside than on the dawnside. Because this asymmetry can ...
Hall effect control of magnetotail dawn-dusk asymmetry: A three-dimensional global hybrid simulation
(2022-10-27)
Magnetotail reconnection and related phenomena (e.g., flux ropes, dipolarizing flux bundles, flow bursts, and particle injections) occur more frequently on the duskside than on the dawnside. Because this asymmetry can ...
The Hall Electric Field in Earth's Magnetotail Thin Current Sheet
(2020-05-28)
One of the most important properties of Earth's magnetotail thin current sheet (TCS) is that its current is predominantly contributed by magnetized electrons. The Hall electric field, normal to the TCS and generated by ...
The Hall Electric Field in Earth's Magnetotail Thin Current Sheet
(2023-01-19)
One of the most important properties of Earth's magnetotail thin current sheet (TCS) is that its current is predominantly contributed by magnetized electrons. The Hall electric field, normal to the TCS and generated by ...
Hard and Soft Anatomy in Two Genera of Dondersiidae (Mollusca, Aplacophora, Solenogastres)
(2020-02-26)
Phylogenetic relationships and identifications
in the aplacophoran taxon Solenogastres (Neomeniomorpha)
are in flux largely because descriptions of hard parts––
sclerites, radulae, copulatory spicules––and body shape
have ...
Heat-induced maternal effects shapes avian eggshell traits and embryo response to high temperatures
(2021-03-29)
Populations without a sufficient rate of genetic adaptation may risk extinction in the face of rapid environmental change, however, phenotypic plasticity can facilitate their persistence. For example, mothers can prepare ...
Hemichordate Molecular Phylogeny Reveals a Novel Cold-Water Clade of Harrimaniid Acorn Worms
(2022-03-04)
Hemichordates are instrumental to understanding early deuterostome and chordate evolution, yet diversity and relationships within the group have been understudied. Recently, there has been renewed interest in hemichordate ...
High activity before breeding improves reproductive performance by enhancing mitochondrial function and biogenesis
(2022-03-13)
Understanding of physiological responses of organisms is typically based on data collected during an isolated event. Although many fundamental insights have been gained from these studies, evaluating the response to a ...
High-Throughput Sequencing Characterizes Intertidal Meiofaunal Communities in Northern Gulf of Mexico (Dauphin Island and Mobile Bay, Alabama)
(2019-12-20)
Abstract. Meiofauna are important components of food webs and for nutrient exchange between the benthos and water column. Recent studies have focused on these communities in the Gulf of Mexico due to potential impacts of ...
Highly accurate potential energy surface for the He-H-2 dimer
(2020-01-16)
A new highly accurate interaction potential is constructed for the He–H2 van der Waals complex. This
potential is fitted to 1900 ab initio energies computed at the very large-basis coupled-cluster level
and augmented by ...
Host preference and habitat segregation among Red Sea anemonefish: effects of sea anemone traits and fish life stages
(2022-03-04)
Competition drives habitat segregation between adults and juveniles in many types of organisms, but little is known about this process in anemonefish that compete for host sea anemones which differ in habitat quality. We ...
Hybrid simulation of foreshock waves and ion spectra and their linkage to cusp energetic ions
(2020-06-16)
A three-dimensional global hybrid simulation is carried out to investigate energetic ions and electromagnetic waves in the quasi-parallel (Q-parallel to) bow shock and cusp for a typical interplanetary magnetic field ...

(2022-10-25)
A three-dimensional global hybrid simulation is carried out to investigate energetic ions and electromagnetic waves in the quasi-parallel (Q-parallel to) bow shock and cusp for a typical interplanetary magnetic field ...
Hybrid simulation of mode conversion at the magnetopause
(2020-06-16)
Two-dimensional hybrid simulations are used to investigate how fast-mode compressional waves incident on a magnetopause current layer mode convert both linearly and nonlinearly to short wavelength (k(perpendicular to)rho(i) ...

Impact Gardening as a Constraint on the Age, Source, and Evolution of Ice on Mercury and the Moon
(2022-10-26)
We update an analytic impact gardening model (Costello et al., 2018, https://doi.org/10.1016/j.icarus.2018.05.023) to calculate the depth gardened by impactors on the Moon and Mercury and assess the implications of our ...
An in vivo test of the biologically relevant roles of carotenoids as antioxidants in animals
(2022-03-13)
Carotenoids are well known for their contribution to the vibrant coloration of many animals and have been hypothesized to be important antioxidants. Surprisingly few examples of carotenoids acting as biologically relevant ...
Increased cellular free cholesterol in macrophage-specific Abca1 knock-out mice enhances pro-inflammatory response of macrophages
(2021-03-23)
Macrophage-specific Abca1 knock-out (Abca1(-M/-M)) mice were generated to determine the role of macrophage ABCA1 expression in plasma lipoprotein concentrations and the innate immune response of macrophages. Plasma lipid ...
Increased nitrogen export from eastern North America to the Atlantic Ocean due to climatic and anthropogenic changes during 1901-2008
