Achieving health equity through oral health value-based care: a funder's perspective.

Because dental caries is one of the most preventable diseases in the world, poor oral health and inequitable outcomes are not just a failing of our current system of care and financing, but the result of decades of unjust and oppressive systems that were not designed to serve all patients equitably. Reducing these disparities will take deep and intentional work to focus on value, outcomes, and each patient as a whole person. In this article, we describe some of the unique opportunities funders have to listen, learn, and leverage strategies to redesign the oral health system in a way that prioritizes historically marginalized people and communities and transforms the way oral health care is accessed, delivered, and received.

Hybrid System of an Optical Nanofibre and a Single Quantum Dot Operated at Cryogenic Temperatures.

Recent progress in quantum nanophotonics brings novel ways for manipulating single photons in various nano-waveguides. Among them, one promising approach is to use optical nanofibres (ONFs), tapered optical fibres with sub-wavelength diameter waists. Here, we develop a hybrid system of an ONF and a single quantum dot (QD) operated at cryogenic temperatures.

Degree of bilingualism modifies executive control in Hispanic children in the USA.

Past studies examining the cognitive function of bilingual school-aged children have pointed to enhancements in areas of executive control relative to age-matched monolingual children. The majority of these studies has tested children from a middle-class background and compared performance of bilinguals as a discrete group against monolinguals. The objective of the present study was to determine if cognitive enhancement from bilingualism is sensitive to the child's degree of bilingualism in a sample of eight- and nine-year old Spanish-English bilingual children of low socioeconomic status.

Fabrication of 1-D Photonic Crystal Cavity on a Nanofiber Using Femtosecond Laser-induced Ablation.

We present a protocol for fabricating 1-D Photonic Crystal (PhC) cavities on subwavelength-diameter tapered optical fibers, optical nanofibers, using femtosecond laser-induced ablation. We show that thousands of periodic nano-craters are fabricated on an optical nanofiber by irradiating with just a single femtosecond laser pulse. For a typical sample, periodic nano-craters with a period of 350 nm and with diameter gradually varying from 50 - 250 nm over a length of 1 mm are fabricated on a nanofiber with diameter around 450 - 550 nm.
