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

open access: yesJournal 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.

Bias‐Field Free Single‐Frequency CW‐ODMR of Nitrogen‐Vacancy Centers in Diamond for the Detection of Transient Electrical Signals

open access: yesAdvanced Materials Interfaces, Volume 13, Issue 13, 7 July 2026.
Simplified quantum sensing technique for the detection of short electrical signals occurring in neuronal signaling or bioinspired technologies. We demonstrate a single frequency continuous‐wave optically detected magnetic resonance (CW‐ODMR) approach to sense signals that can be as short as 0.2 ms.

MRI Goes Mobile: Assessing the Reliability and Repeatability of a Mobile vs. Stationary 1.5 T MRI for Functional Neuroscience Studies

open access: yesNMR in Biomedicine, Volume 39, Issue 7, July 2026.
We present a technical feasibility study validating two mobile 1.5 T MRI scanners against a stationary system using a five‐subject test‐retest protocol (N = 50 datasets). Following relocation, hardware performance remained stable, with no systematic bias in B0 homogeneity or B1+ maps.

A Low‐Power Cryogenic Low‐Noise Amplifier for the Next‐Generation Quantum Computers

open access: yesphysica status solidi (a), Volume 223, Issue 11, 10 June 2026.
Next generation of quantum computers calls for reduced dc power dissipation of the cryogenic low‐noise amplifier (LNA) applied in reading out the superconducting qubits. This article reports on processing and evaluation of a 100‐nm gate length indium phosphide high electron mobility transistor (InP HEMT) technology used in the design of such LNAs.
