Previous studies have identified negative impacts of the COVID-19 pandemic on the mental and physical health of children in the United States, including exacerbation of previously existing disparities according to income, race, and ethnicity. However, a knowledge gap exists regarding the experience of minority families who were disproportionately affected by the pandemic. This qualitative study explores publicly insured Hispanic families' experiences with school, physical, and sedentary activities and overall health and well-being during the pandemic and subsequent lifting of stay-at-home orders.

Facial grimacing is used to quantify spontaneous pain in mice and other mammals, but scoring relies on humans with different levels of proficiency. Here, we developed a cloud-based software platform called PainFace ( http://painface.net ) that uses machine learning to detect 4 facial action units of the mouse grimace scale (orbitals, nose, ears, whiskers) and score facial grimaces of black-coated C57BL/6 male and female mice on a 0 to 8 scale.

Texturing can be used to functionalize the surface of plastic parts and, in particular, to modify the interaction with fluids. Wetting functionalization can be used for microfluidics, medical devices, scaffolds, and more. In this research, hierarchical textures were generated on steel mold inserts using femtosecond laser ablation to transfer on plastic parts surface via injection molding.

It is well established that mantle plumes are the main conduits for upwelling geochemically enriched material from Earth's deep interior. The fashion and extent to which lateral flow processes at shallow depths may disperse enriched mantle material far (>1,000 km) from vertical plume conduits, however, remain poorly constrained. Here, we report He and C isotope data from 65 hydrothermal fluids from the southern Central America Margin (CAM) which reveal strikingly high He/He (up to 8.

Patients with limited English-proficiency (LEP) who need but do not receive interpreters have lower satisfaction and poorer understanding. A knowledge gap remains regarding the optimal way to offer interpreters. Using standardized scripts, we will determine whether the questions we use to offer interpreters increase utilization.
