Where the Mineral Kingdom Might Hide New Forms of Matter

open access: yesPerspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract Mineralogy has traditionally classified matter primarily through local chemistry and diffraction symmetry. But some physically distinct states of matter differ neither principally in composition nor in obvious diffraction symmetry; they differ in how fluctuations behave over very large distances.

Can Annotation‐Free Deep Learning Detect Periapical Bone Rarefactions on Panoramic Radiographs? A Paired Diagnostic Validation Study

open access: yesInternational Journal of Imaging Systems and Technology, Volume 36, Issue 6, November 2026.
ABSTRACT This study aimed to compare an annotation‐free deep learning (DL) model with human evaluators for detecting periapical bone rarefactions (PBRs) on panoramic radiographs (PRs) and to assess the clinical acceptability of AI‐supported dental imaging.

Estimating Regional Snow Water Equivalent Using a Physics‐Informed Graph Convolution Network Model

open access: yesEarth and Space Science, Volume 13, Issue 11, November 2026.
Abstract Snow water equivalent (SWE), which quantifies the amount of water in a snowpack, is critical for water supply forecasting. This study explores machine learning (ML) models' capability of representing the spatial distribution of SWE across the western United States.

Numerical Modeling of Geothermal Heat and Lithium Co‐Production in Fault‐Hosted Reservoirs

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 11, November 2026.
Abstract The global transition to low‐carbon energy systems is driving demand for lithium, a critical raw material for battery storage technologies. Geothermal brines, particularly in the Upper Rhine Graben (URG) in western Europe, offer a potential lithium source co‐produced with heat, providing economic and strategic benefits.

PROSWIN: Probabilistic Solar Wind Speed Forecasting Using Deep Distributional Regression From Solar Images

open access: yesAGU Advances, Volume 7, Issue 8, November 2026.
Abstract Accurately predicting fast solar wind conditions is challenging, as uncertainties are large and unquantified by traditional single‐value prediction models. In particular, the risks of high‐speed solar wind streams (HSSs), which can cause damage to technological infrastructure, cannot be reliably assessed without probabilistic forecasts.

Line‐Based Levee Detection: A New Generation of Levee Detection Methods Using Digital Elevation Models

open access: yesEarth and Space Science, Volume 13, Issue 11, November 2026.
Abstract Levee location information is an essential input for accurate flood simulation. Several methods for detecting levees from LiDAR digital elevation models have been proposed in recent years. However, these detection methods are pixel‐based, treating continuous levees as discrete points, classifying each pixel as levee or non‐levee.

Charge Exchange in Laboratory and Astrophysical Plasmas

open access: yesInternational Astronomical Union Colloquium, 1988
AbstractRecent experiments in tokamak plasmas demonstrate that charge exchanges manifest themselves in a wide variety of situations. It is now realized that charge exchanges involving excited states of hydrogen should be considered: these reactions represent a challenge for atomic physics, detailed plasma modeling, and quantitative plasma diagnostics ...

Suprathermal Electron Acceleration Comparison of the Venusian and Terrestrial Bow Shocks

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 11, November 2026.
Abstract We study suprathermal electron acceleration at the Venusian bow shock using the Parker Solar Probe gravity assists and the Venus Express spacecraft mission. The acceleration is classified by measuring the maximum energy and the power‐law spectral slope (index) of the electron phase space density immediately downstream of the shocks for ...

Van Allen Probes Observations of a Fundamental Poloidal Wave in the Plasmasphere

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 11, November 2026.
Abstract All past spacecraft observations of fundamental poloidal Alfvén (P1) waves attributed to ion drift resonance have been made outside the plasmasphere. In this study, we present the first spacecraft observations of a plasmaspheric P1 wave driven by that resonance.

Is Magnetic Reconnection Dominantly Spatially or Temporally Variable: First Results From TRACERS

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 11, November 2026.
Abstract The Tandem Reconnection And Cusp Electrodynamics Reconnaissance Satellites (TRACERS) small explorer mission was designed to: Determine whether magnetopause reconnection is primarily spatially or temporally variable for a range of solar wind conditions. Observations from the Analyzers for Cusp Ions (ACIs) on the two TRACERS spacecrafts are used
