Developing a Public Health Course to Train Undergraduate Student Health Messengers to Address Vaccine Hesitancy in an American Indian Community.

The purpose of the Diné Teachings and Public Health Students Informing Peers and Relatives about Vaccine Education (RAVE) project was to develop strategies for health communication that addressed COVID-19 vaccine safety for residents of the Navajo Nation. The RAVE project developed a 16-week course using the Diné Educational Philosophy as a framework to train Diné College (DC) public health undergraduate students ( = 16) as health messengers to share COVID-19 vaccine safety information with unvaccinated peers and relatives. An online community survey ( = 50) was used to assess DC community vaccination perceptions to guide course development.

An Assessment of Back and Shoulder Postures in Single-Handed Exertions: Expanding Ergonomic Reaching Guidelines to Consider Lumbar Spine Axial Twist.

Occupational applicationsAcross a series of standing single-handed exertions performed at different lateral angles, distances, heights, and loads, lumbar axial twist exceeded an angular threshold of 9° in select exertions. Specifically, 9° of rightward axial twist was exceeded for all exertions performed laterally (90° from the body midline). Additionally, for those at the body midline, 9° of leftward axial twist was exceeded for upward exertions and exertions performed at far distances (tertiary reach envelope).

Elucidating ultranarrow F to F absorption in ytterbium(iii) complexes.

Achieving ultranarrow absorption linewidths in the condensed phase enables optical state preparation of specific non-thermal states, a prerequisite for quantum-enabled technologies. The 4f orbitals of lanthanide(iii) complexes are often referred to as "atom-like," reflecting their isolated nature, and are promising substrates for the optical preparation of specific quantum states. To better understand the photophysical properties of 4f states and assess their potential for quantum applications, theoretical building blocks are required for rapid screening.

Toward liquid cell quantum sensing: Ytterbium complexes with ultranarrow absorption.

The energetic disorder induced by fluctuating liquid environments acts in opposition to the precise control required for coherence-based sensing. Overcoming fluctuations requires a protected quantum subspace that only weakly interacts with the local environment. We report a ytterbium complex that exhibited an ultranarrow absorption linewidth in solution at room temperature with a full width at half maximum of 0.
