Magnetic flux rope formation within a magnetosheath hot flow anomaly
(2020-06-09)
We report observations on 1 March 2004 by the Cluster spacecraft of a hot flow anomaly (HFA) encountered in the dayside magnetosheath near Earth's bow shock. Embedded within the HFA was a magnetic flux rope with a diameter ...
Global-scale hybrid simulation of cusp precipitating ions associated with magnetopause reconnection under southward IMF
(2020-06-09)
With a 3-D global-scale hybrid simulation model, we investigate the energy spectra of cusp precipitating ions and issues associated with magnetopause reconnection under a southward IMF. Both the spatial and temporal energy ...
Two-dimensional global hybrid simulation of pressure evolution and waves in the magnetosheath
(2020-06-30)
A two-dimensional hybrid simulation is carried out for the global structure of the magnetosheath. Quasi-perpendicular magnetosonic/fast mode waves with large-amplitude in-phase oscillations of the magnetic field and the ...
Accurate virial coefficients of gaseous krypton from state-of-the-art ab initio potential and polarizability of the krypton dimer
(2020-06-25)
We have developed a new krypton-krypton interaction-induced isotropic dipole polarizability curve based on high-level ab initio methods. The determination was carried out using the coupled-cluster singles and doubles plus ...
Global hybrid simulation of the dayside reconnection layer and associated field-aligned currents
(2020-06-26)
A two-dimensional global hybrid simulation is carried out to study the structure of the magnetopause boundary layer in the noon-midnight meridian plane associated with the dayside reconnection. In the simulation the bow ...
Generation of anomalous flows near the bow shock by its interaction with interplanetary discontinuities
(2020-06-30)
Two-dimensional hybrid simulations using a curvilinear coordinate system are carried out to study the interaction of the Earth's bow shock (BS) with an interplanetary directional discontinuity. In particular, plasma flow ...
Overlap of the plasmasphere and ring current: Relation to subauroral ionospheric heating
(2020-06-18)
The overlap of the ring current with the outer plasmasphere is thought to play a major role in storm-time related increases in the subauroral ambient topside electron temperature. Instabilities generated within the overlap ...
Magnetic field rotation and transition width in rotational discontinuities and Alfven wave trains
(2020-06-30)
A hybrid simulation is carried out to study the evolution of magnetic field rotations in rotational discontinuities (RDs) and large-amplitude Alfven wave trains (AWTs) whose initial field rotation angle \Delta Phi\ > 180 ...
Lattice thermal conductivity of MgO at conditions of Earth's interior
(2020-06-29)
Thermal conductivity of the Earth’s lower mantle greatly impacts the mantle convection style and affects the heat conduction from the core to the mantle. Direct laboratory measurement of thermal conductivity of mantle ...
DAVIS: A direct algorithm for velocity-map imaging system
(2020-06-25)
In this work, we report a direct (non-iterative) algorithm to reconstruct the three-dimensional (3D) momentum-space picture of any charged particles collected with a velocity-map imaging system from the two-dimensional ...
Interpretation of the photoelectron spectra of superalkali species: Li3O and Li3O-
(2020-10-02)
The present paper deals with the interpretation of the photoelectron spectrum of the Li3O-. After several failed attempts to attribute all of the observed peaks in the experimental spectrum to anionic species, neutral ...
Data for A chromosome-level genome assembly for the Eastern Fence Lizard (Sceloporus undulatus), a reptile model for physiological and evolutionary ecology
(2021-04-16)
Background: High-quality genomic resources facilitate investigations into behavioral ecology, morphological and physiological adaptations, and the evolution of genomic architecture. Lizards in the genus Sceloporus have a ...
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 ...
Images of natural comb

BAM files associated with Macaca arctoides hybridization analysis
(2022-10-12)
Genital divergence is thought to contribute to reproductive barriers by establishing a “lock-and-key" mechanism for reproductive compatibility. One such example, Macaca arctoides, the bear macaque, has compensatory changes ...
Re-Reconnection Processes of Magnetopause Flux Ropes: Three-Dimensional Global Hybrid Simulations
(2022-10-18)
Magnetopause flux ropes (FRs) play a crucial role in the transport of energy and plasma from the solar wind to the Earth's magnetosphere. Once formed by multiple X-line reconnection, the FRs move poleward, during which ...
