Group‐Patch Joint Compression: Compressing Dynamic B0 and Static RF Spatial Modulations Across k‐Space Subregion Groups for Highly Accelerated MRI

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To accelerate MRI further, rapid B0 field modulations can be applied during oversampled readout to capture additional physical information, as in Wave‐CAIPI/FRONSAC/local B0 coils modulation techniques. These methods, however, turn the Fourier readout into a non‐Fourier‐encoded dimension that cannot be reconstructed by FFT, posing ...

Fault Detection of Electric Motors via Symmetrized Dot Pattern‐Based Features

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT This study proposes a novel symmetrized dot pattern (SDP) approach using designed SDP‐based features, extracted from transformed vibration signals, for fault detection. These features describe the compactness, inclination, and shape of the “snowflake” diagram distributions.

From Connections to Actions: When Do Government Ties Matter to Nonprofit Organizational Performance?

open access: yesPublic Administration and Development, EarlyView.
ABSTRACT Nonprofit organizations are essential for public service delivery, yet the value of their government ties is contested. This study examines the mechanism that translates these connections into tangible results. We propose that political networking—the deliberate cultivation and use of official relationships—is the critical catalyst.

Study of the Effects of Mold Coating on the Birefringence of Injection‐Molded Optical‐Quality Polycarbonate

open access: yesPolymer Engineering &Science, EarlyView.
Experimental and numerical evaluation of birefringence of injection molded parts ABSTRACT This study investigates the impact of mold surface coatings on the birefringence of injection‐molded optical‐quality polycarbonate lenses. Birefringence, caused by residual stresses during molding, affects optical clarity and performance.
