Automated Mineral Identification and Rock‐Type Classification of Lunar Mare Basalts Using SEM Images

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract We present an automated system for identifying minerals and classifying rock types in Apollo lunar mare basalts using scanning electron microscopy (SEM) imagery. Mineral segmentation is based on a U‐Net architecture, supplemented by two scale‐aware models designed to incorporate pixel size information.

A Moonshine Dialogue in Mathematical Physics

Mathematics, 2015
Phys and Math are two colleagues at the University of Saçenbon (Crefan Kingdom), dialoguing about the remarkable efficiency of mathematics for physics. They talk about the notches on the Ishango bone and the various uses of psi in maths and physics; they

A Kolmogorov–Arnold Surrogate Model for Chemical Equilibria: Application to Solid Solutions

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract The computational cost of geochemical solvers is a challenging matter. For reactive transport simulations, where chemical calculations are performed up to billions of times, it is crucial to reduce the total computational time. Existing publications have explored various machine learning approaches to determine the most effective data‐driven ...

Simultaneous all-versus-nothing refutation of local realism and noncontextuality by a single system

Results in Physics
The quantum realms of nonlocality and contextuality are delineated by Bell’s theorem and the Kochen–Specker theorem, respectively, embodying phenomena that surpass the explanatory capacities of classical theories.

Finding an almost perfect matching in a hypergraph avoiding forbidden submatchings

Journal of the London Mathematical Society, Volume 114, Issue 2, August 2026.
Abstract In 1973, Erdős conjectured the existence of high girth (n,3,2)$(n,3,2)$‐Steiner systems. Recently, Glock, Kühn, Lo, and Osthus and independently Bohman and Warnke proved the approximate version of Erdős' conjecture. Recently, Kwan, Sah, Sawhney, and Simkin proved Erdős' conjecture.

Connecting extended Wigner's friend arguments and noncontextuality [PDF]

Quantum
The Local Friendliness argument is an extended Wigner's friend no-go theorem that provides strong constraints on the nature of reality – stronger even than those imposed by Bell's theorem or by noncontextuality arguments. In this work, we prove a variety

A Dialogue on Revolutions and Revolutionaries in Science: A Perspective From Quantum Mechanics

Natural Sciences, Volume 6, Issue 3, July 2026.
ABSTRACT We discuss the notions of scientific revolutions and revolutionaries in the context of the Relativity Revolution and of the First, Second, and Third Quantum Revolutions. We conclude that at the core of the question of what qualifies as a revolution and revolutionary is an assessment of the gradients of knowledge accumulation over time, both at

Relating Wigner's Friend Scenarios to Nonclassical Causal Compatibility, Monogamy Relations, and Fine Tuning [PDF]

Quantum
Nonclassical causal modeling was developed in order to explain violations of Bell inequalities while adhering to relativistic causal structure and $faithfulness$---that is, avoiding fine-tuned causal explanations.

Magnetic Signature of the Corona Lava Tube (Lanzarote, Canary Islands), a Lunar and Martian Planetary Analog

Journal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.
Abstract Lava tubes and caves are key exploration targets on the Moon and Mars due to their potential to serve as natural infrastructure for future crewed missions. However, identifying these structures efficiently and reliably remains a major challenge.
