Robust High-Dynamic-Range Vector Magnetometry via Nitrogen-Vacancy Centers in Diamond

, 2018
We demonstrate a robust, scale-factor-free vector magnetometer, which uses a closed-loop frequency-locking scheme to simultaneously track Zeeman-split resonance pairs of nitrogen-vacancy (NV) centers in diamond.

Midbrain PAG Astrocytes Modulate Mouse Defensive and Panic‐Like Behaviors

Advanced Science, EarlyView.
Astrocytes in the midbrain periaqueductal gray (PAG) dynamically encode threat intensity and shape defensive action selection in mice. Real‐time Ca2+ imaging reveals robust astrocytic activation during predator odor and CO2 exposure. Aberrant astrocytic Ca2+ overactivation disrupts goal‐directed escape, biases behavior toward freezing, and induces ...

Health disparities in chronic liver disease

Hepatology, EarlyView., 2022
Abstract The syndemic of hazardous alcohol consumption, opioid use, and obesity has led to important changes in liver disease epidemiology that have exacerbated health disparities. Health disparities occur when plausibly avoidable health differences are experienced by socially disadvantaged populations.
