Investigating the origin of the 13C lactate signal in the anesthetized healthy rat brain in vivo after hyperpolarized [1-13C]pyruvate injection
The goal of this study was to investigate the origin of brain lactate (Lac) signal after injection of hyperpolarized (HP) [1-13C]pyruvate (Pyr).

Age-Accelerated Increase of White Matter Hyperintensity Volumes Is Exacerbated by Heavy Alcohol Use in People Living With HIV
Antiretroviral treatment has enabled people living with HIV infection to have a near-normal life span. With longevity comes opportunities for engaging in risky behavior, including initiation of excessive drinking. Given…

Sleep, brain systems, and persistent stress in early adolescents during COVID-19: Insights from the ABCD study
Here, we analyzed clusters of perceived stress levels across the pandemic and determined developmentally relevant pre-pandemic risk factors in brain structure and sleep of persistently high stress during the first…

Frontal cortical volume deficits as enduring evidence of childhood abuse in community adults with AUD and HIV infection comorbidity
Here, we examined the neural and behavioral correlates of childhood trauma history in alcohol use disorder (AUD), HIV infection (HIV), and their comorbidity (AUD+HIV).

Stable, narrow-linewidth laser system with a broad frequency tunability and a fast switching time
Through Rydberg atom-based sensing experiments, we demonstrate frequency hopping between two Rydberg states and a fast switching time of 400 μs, which we show can be reduced to ∼50 μs with a…

Unsupervised Domain Adaptation for Semantic Segmentation with Pseudo Label Self-Refinement
We propose an auxiliary pseudo-label refinement network (PRN) for online refining of the pseudo labels and also localizing the pixels whose predicted labels are likely to be noisy.

Closed-loop quantum interferometry for phase-resolved Rydberg-atom field sensing
In this work, we demonstrate that closed-loop quantum interferometric schemes can be used to generate a system-internal reference that can directly replace an external LO for Rydberg field sensing.

Efficient Quantum Algorithms for Nonlinear Stochastic Dynamical Systems
In this paper, we propose efficient quantum algorithms for solving nonlinear stochastic differential equations (SDE) via the associated Fokker-Planck equation (FPE).

Improving Participation in High-Quality Early Care and Education for Young Arkansas Children: Perspectives of Resource Parents and Early Childhood Educators
This brief presents key findings from focus groups and interviews with resource parents (that is, foster parents), ECE center-based program directors, and ECE home-based providers about their experiences caring for…

Contributions of Cerebral White Matter Hyperintensities to Postural Instability in Aging With and Without Alcohol Use Disorder
Both postural instability and brain white matter hyperintensities (WMHs) are noted markers of normal aging and alcohol use disorder (AUD). Here, we questioned what variables contribute to the sway path–WMH…
