A Simulation Study of an HFA-like Event at Mars

The Astrophysical Journal
Hot flow anomalies (HFAs) are transient structures at planetary bow shocks characterized by hot, tenuous plasma. At Mars, where no global dipole field exists, such events interact with the induced magnetosphere in a unique and poorly understood way. This

Continuous and Burst-like Accretion onto Substellar Companions in Mira Winds [PDF]

, 2003
We present numerical hydrodynamical modeling of the effects of a giant planet or brown dwarf companion orbiting within the extended atmosphere and wind formation zone of an approximately solar-mass Mira variable star.

Lentipes ptasan, a new species of sicydiine goby (Teleostei: Gobioidei) from the Western Pacific, with a redescription of L. mindanaoensis

Journal of Fish Biology, EarlyView.
Abstract Lentipes ptasan sp. nov. is described based on specimens collected from Taiwan and Mindanao Island. It is a large‐sized Lentipes species distinguished by several male‐specific characteristics, including an upper lip protruding beyond snout obviously, fewer premaxillary tricuspid teeth, two black lines running from the front of the eye through ...

A leucine‐rich‐repeat receptor‐like kinase SERL1 phosphorylates and stabilizes OsALDH2B1 to promote alkaline tolerance and grain size in rice

Journal of Integrative Plant Biology, EarlyView.
The rice aldehyde dehydrogenase OsALDH2B1 enhances grain size and tolerance to alkaline soil by repressing GRAIN SIZE 3 and activating catalases. SERL1‐mediated phosphorylation stabilizes OsALDH2B1 under stress, establishing a signaling axis that overcomes growth‐defense trade‐offs and provides a direct target for breeding high‐yield, alkaline ...

Interplanetary Magnetic Field Effect on the Location of the Martian Bow Shock: MAVEN Observations

The Astrophysical Journal, 2023
The Martian bow shock (BS) is generated with the mass-loading and magnetic pileup processes when the solar wind interacts with the Martian ionosphere. In this vein, the interplanetary magnetic field (IMF) frozen in the solar wind can affect the location ...

Different types of ion populations upstream of the 8 October 2013 interplanetary shock

, 2017
We show for the first time that different types of suprathermal ion distributions may exist upstream of a single interplanetary shock. ACE and the two ARTEMIS satellites observed a shock on 8 October 2013.

Integrative taxonomy supports DNA barcoding in revealing an abundant cryptic species in the United States Coastal Plain

Journal of Systematics and Evolution, EarlyView.
We present the most densely sampled phylogeny of Carex section Lupulinae to date (107 specimens) and describe herein a new cryptic species for science from the southern United States, which is locally abundant and found in well‐explored and densely populated areas. Combining DNA sequences with morphometric data obtained from 299 samples, we Demonstrate

Energy Dissipation in Strong Collisionless Shocks: The Crucial Role of Ion-to-electron Scale Separation in Particle-in-cell Simulations

The Astrophysical Journal Letters
Energy dissipation in collisionless shocks is a key mechanism in various astrophysical environments. Its nonlinear nature complicates analytical understanding and necessitates particle-in-cell (PIC) simulations. This study examines the impact of reducing

Cluster magnetic field observations at a quasi-parallel bow shock [PDF]

Annales Geophysicae, 2002
We present four-point Cluster magnetic field data from a quasi-parallel shock crossing which allows us to probe the three-dimensional structure of this type of shock for the first time. We find that steepened ULF waves typically have a scale larger
