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

From wild to tamed: Reimagining novel crops through omics and local plant diversity

PLANTS, PEOPLE, PLANET, EarlyView.
The global food system faces growing pressure from climate change, biodiversity loss, and rising nutritional demands. Agriculture has increased yields but reduced crop diversity, flavor, and nutritional quality, leaving societies vulnerable and dependent on a narrow set of staple species.

New stellar bow shocks and bubbles found around runaway stars [PDF]

Context. Runaway stars with peculiar high velocities can generate stellar bow shocks. Only a few bow shocks show clear radio emission. Aims. Our goal is to identify and characterize new stellar bow shocks around O and Be runaway stars in the infrared (IR)

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

Observations of the spatial and temporal structure of field-aligned beam and gyrating ring distributions at the quasi-perpendicular bow shock with Cluster CIS [PDF]

Annales Geophysicae, 2001
During the early orbit phase, the Cluster spacecraft have repeatedly crossed the perpendicular Earth’s bow shock and provided the first multi-spacecraft measurements. We have analyzed data from the Cluster Ion Spectrometry experiment (CIS), which

Assessing National Sustainability Transitions in Europe: A Dynamic MCDA and Clustering‐Based Approach

Sustainable Development, EarlyView.
ABSTRACT The study evaluates the sustainable development of 42 European countries using a multi‐criteria decision analysis (MCDA) approach, based on 29 indicators covering the economic, social, and environmental pillars. All three pillars are assessed both individually and in consolidated form to provide a comprehensive view of countries ...

From Proxies to System State: Defining Sustainability Management Against Symbolic Progress

Sustainable Development, EarlyView.
ABSTRACT Sustainability in management is often measured through scores, ratings, and disclosure narratives that can reward symbolic progress while leaving underlying social‐ecological conditions unchanged. This perspective paper offers a definition of Sustainability Management as how organizations plan, organize, lead, and control (four management ...

On the Formation of Super-Alfvénic Flows Downstream of Collisionless Shocks

The Astrophysical Journal
Super-Alfvénic jets, with kinetic energy densities significantly exceeding that of the solar wind, are commonly generated downstream of Earth's bow shock under both high- and low-beta plasma conditions. In this study, we present theoretical evidence that

Spatial distribution of upstream magnetospheric ≥50 keV ions [PDF]

Annales Geophysicae, 2000
We present for the first time a statistical study of \geq50 keV ion events of a magnetospheric origin upstream from Earth's bow shock. The statistical analysis of the 50-220 keV ion events observed by the IMP-8 spacecraft shows: (1) a dawn-dusk ...

CONTESTED METABOLIC NODES: Shareholding Cooperatives and Planetary Ruralization in China

International Journal of Urban and Regional Research, EarlyView.
Abstract China's recent shareholding cooperative (SC) reform heralds a shift from expropriation‐led rural change to a post‐expropriation regime in which the countryside is reconstituted through circulation, capitalization, and new forms of collective governance. Existing interpretations, whether framed as market‐driven de‐collectivization, state‐led re‐
