Scalable spokes pTx pulses for 2D turbo‐spin‐echo imaging at 7 T
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).

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
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 ...

Failure Criterion‐Based Bead Optimization of a Wind Turbine Blade Root Section
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 ...
