A Three‐Dimensional Structural Model for Predicting Magnetic Exchange and Hydrogen Positions in Bis‐μ‐Hydroxido Cu(II) Dimers

European Journal of Inorganic Chemistry, Volume 29, Issue 17, 17 June 2026.
Magneto‐structural correlation in bis‐μ‐hydroxido Cu(II) dimers: The out‐of‐plane angle (α) of bridging hydroxido groups critically influences the exchange coupling constant (J). A three‐dimensional correlation combining α and the Cu‐OH‐Cu angle (θ) enables computationally accurate J prediction.

First Results of a New Inversion Tool for Thermospheric Neutral Mass Density Computations During Severe Geomagnetic Storms

AGU Advances, Volume 7, Issue 3, June 2026.
Abstract In Low Earth Orbit (LEO), atmospheric drag is the dominant source of trajectory prediction error below approximately 700 km altitude, primarily due to inaccuracies in thermospheric density models. This work presents a method for temporally deconvolving Energy Dissipation Rates (EDRs) to produce single‐satellite density estimates, which can be ...

Persistent feature reconstruction of resident space objects (RSOs) within inverse synthetic aperture radar (ISAR) images

CoRR
With the rapidly growing population of resident space objects (RSOs) in the near-Earth space environment, detailed information about their condition and capabilities is needed to provide Space Domain Awareness (SDA). Space-based sensing will enable inspection of RSOs at shorter ranges, independent of atmospheric effects, and from all aspects.

Vast, overlooked peat, and organic soils in Brazil's Cerrado: carbon storage, dynamics, and stability

New Phytologist, Volume 250, Issue 5, Page 2946-2965, June 2026.
Summary Tropical peatlands are critical for climate mitigation due to their dual role as major carbon sinks and methane sources. In rainforests, high and stable rainfall supports peat accumulation in tropical climates. However, groundwater‐fed peatlands in seasonally dry tropical ecosystems remain poorly understood, despite their potential importance ...

RESIDENT SPACE OBJECTS DETECTION AND TRACKING BASED ON ARTIFICIAL INTELLIGENCE

, 2022
Resident Space Objects (RSOs) detection and tracking are challenging problems in the framework of Space Situational Awareness (SSA). The growing number of in orbit platforms and the incoming era of mega constellations is increasing both active and ...

Again/st the Mad Subject 1

Nursing Philosophy, Volume 27, Issue 2, April 2026.
ABSTRACT Although widely contested, psychiatry continues to function as a dominant governing framework for mental distress within contemporary healthcare. While critiques of psychiatry have proliferated across survivor movements, mad studies, neurodiversity advocacy, and critical nursing scholarship, much of this work remains tethered to humanist ...

Supermarket Settings and Consumer Behavior: A Systematic Mapping Review and Future Research Avenues

International Journal of Consumer Studies, Volume 50, Issue 2, March 2026.
ABSTRACT Supermarkets and related environments are not just places to buy groceries; they are complex environments filled with diverse stimuli that shape consumer behavior and decision‐making processes. Despite their increasing use as study settings, there remains a lack of comprehensive understanding regarding which supermarket‐type settings are ...

RESIDENT SPACE OBJECT IDENTIFICATION IN ARBITRARY UNRESOLVED SPACE IMAGES

, 2023
Identifying resident space objects (RSOs) in arbitrary space imagery with little a-priori information is a challenging, yet crucial next step in space-domain awareness applications.

Ionospheric Corrections for Space Domain Awareness Using HF Line-of-Sight Radar

Remote Sensing
As the near-Earth space domain becomes increasingly congested, the field of space domain awareness (SDA) has risen in importance and motivated the use of non-traditional sensors.
