Precipitation mechanism of anhydrite cement in lacustrine tight sandstone: Implications for fluid activity, mass transfer and pore origin of open diagenetic system in tight sandstone

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).

T1‐weighted fMRI in mouse visual cortex using an iron oxide nanoparticle contrast agent and UTE imaging at 9.4 T

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 ...
