The Depositional Record, Volume 12, Issue 1, February 2026.This paper discusses a new model concerning the precipitation mechanismand significance of anhydrite cement in tight sandstone. Anhydrite cement ismainly formed by the dissolution and reprecipitation of early‐diageneticcalcite cements, feldspars and volcanic rock fragments at the mesodiageneticstage.

Scalable spokes pTx pulses for 2D turbo‐spin‐echo imaging at 7 T
Magnetic Resonance in Medicine, Volume 95, Issue 2, Page 740-755, February 2026.Abstract Purpose Turbo spin echo (TSE) is important clinically. Unfortunately, 7 T TSE suffers from B1+‐induced signal dropouts. Magnitude‐based parallel transmit (pTx) pulse design algorithms cannot enforce phase patterns complying with the Carr‐Purcell‐Meiboom‐Gill conditions (90° phase shift between excitation and refocusing).

Magnetic Resonance in Medicine, Volume 95, Issue 2, Page 680-692, February 2026.Abstract Purpose This study aims to investigate the feasibility of using T1‐weighted fMRI with an iron oxide nanoparticle contrast agent and UTE imaging at 9.4 T to measure functional hyperemia in the mouse visual cortex. The goal is to capture positive signal changes in both the parenchyma and pial surface, and to test whether surface vessels respond ...

Supersaturated Designs for Main Effects and Two‐Factor Interactions
Quality and Reliability Engineering International, Volume 42, Issue 1, Page 52-65, February 2026.ABSTRACT Supersaturated designs (SSDs), which use fewer runs than factors, are employed in screening experiments to identify large main effects (MEs), even when the experimental setting may also involve factors that interact. This paper introduces new SSD design criteria that account for two‐factor interactions (2FIs) and compares them with designs ...

Advanced Quantum Technologies, Volume 9, Issue 2, February 2026.A tool to model ensemble‐based atomic quantum memory experiments using the quantum channel formalism is presented, incorporating realistic loss and noise effects. It provides a digital twin of state‐of‐the‐art memories and demonstrates its applicability through a simulation of a memory‐assisted quantum token protocol. The framework is easily extendable

Failure Criterion‐Based Bead Optimization of a Wind Turbine Blade Root Section
Wind Energy, Volume 29, Issue 2, February 2026.ABSTRACT This study presents a bead‐based optimization framework for fiber composite wind turbine blades, employing the Tsai–Wu failure criterion as the structural performance measure. The objective is to design an optimal transition geometry between an existing blade and a root section with 20% smaller diameter, while preserving the original material ...

Galactic Cosmic Ray Ionization on Uranus; Geomagnetic Latitude Dependencies
Journal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.Abstract Galactic Cosmic Rays (GCRs) are a major source of atmospheric ionization, influencing ion abundance, aerosol formation, and electrical processes. GCR‐induced effects are expected to be more pronounced on Uranus than planets closer to the Sun for two reasons; reduced solar irradiance, and weaker solar modulation of incident GCR.
