Dynamic Transitions for Fast Joint Acquisition and Reconstruction of CEST‐Rex$$ {R}_{ex} $$ and T1$$ {T}_1 $$

Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2153-2168, April 2026.
ABSTRACT Purpose This work proposes a method for the simultaneous estimation of the exchange‐dependent relaxation rate Rex$$ {R}_{ex} $$ and the longitudinal relaxation time T1$$ {T}_1 $$ from a single acquisition. Methods A novel acquisition scheme was developed that combines CEST saturation with an inversion pulse and a Look‐Locker readout to capture

High‐resolution deuterium metabolic imaging of the human brain at 9.4 T using phase‐cycled balanced SSFP spectral–spatial acquisitions

Magnetic Resonance in Medicine, Volume 95, Issue 3, Page 1304-1322, March 2026.
Abstract Purpose The aim was to improve the sensitivity and robustness against B0 inhomogeneities of deuterium metabolic imaging (DMI) using phase‐cycled balanced SSFP (bSSFP) methods at 9.4 T. Methods We investigated two variants of phase‐cycled bSSFP acquisitions, namely uniformly weighted multi‐echo and acquisition‐weighted chemical shift imaging ...

Non‐Negligible Influence of Forcing Mechanisms on Turbulent Mixing at Low Reynolds Numbers: A One‐Dimensional Turbulence Study

PAMM, Volume 26, Issue 1, March 2026.
ABSTRACT This study presents a numerical investigation of passive scalar mixing in homogeneous isotropic turbulence (HIT). Different volumetric forcing schemes have been used in the literature, but the side effects are rarely discussed, either because these are assumed irrelevant or because it is too costly to conduct such an analysis with a high ...

Navigating the Emotional Challenges of Grade School: The Influence of Early Family Strains and a Lack of Parental Responsiveness on Trajectories of Anxiety and Depressive Symptoms

Family Process, Volume 65, Issue 1, March 2026.
ABSTRACT Although parenting is critical to children's emotional development, broader family processes can also play an important role in the development of anxiety and depressive symptoms in children. The current study examined the influence of early family strains (i.e., chronic stressors and resource deficits) on children's trajectories of anxiety ...

Algorithmic Bias in BERT for Response Accuracy Prediction: A Case Study for Investigating Population Validity

Journal of Educational Measurement, Volume 63, Issue 1, Spring 2026.
Abstract Pretrained large language models (LLMs) have gained popularity in recent years due to their high performance in various educational tasks such as learner modeling, automated scoring, automatic item generation, and prediction. Nevertheless, LLMs are black box approaches where models are less interpretable, and they may carry human biases and ...
