Exploring barriers and facilitators of implementing an at-home SARS-CoV-2 antigen self-testing intervention: The Rapid Acceleration of Diagnostics-Underserved Populations (RADx-UP) initiatives.

Background: Evaluating community-based programs provides value to researchers, funding entities, and community stakeholders involved in program implementation, and can increase program impact and sustainability. To understand factors related to program implementation, we aimed to capture the perspective of community partners engaged in organizing and executing community-engaged programs to distribute COVID-19 at-home tests in underserved communities.

Methods: We conducted semi-structured interviews and focus groups with community-based stakeholders informed by the Outcomes for Implementation Research framework.

Image-plane self-calibration in interferometry.

We develop a process of image-plane self-calibration for interferometric imaging data. The process is based on shape-orientation-size (SOS) conservation for the principal triangle in an image generated from the three fringes made from a triad of receiving elements, in situations where interferometric phase errors can be factorized into element-based terms. The basis of the SOS conservation principle is that, for a three-element array, the only possible image corruption due to an element-based phase screen is a tilt of the aperture plane, leading to a shift in the image plane.

Attitudes and perceptions about the use of long-acting injectable antipsychotics among behavioral health practitioners.

Introduction: Long-acting injectable antipsychotics (LAI-As) are important tools for the treatment of schizophrenia, yet they appear to be underutilized. This study will assess practitioner perceptions of LAI-As to elucidate reasons for underuse and uncover new avenues to increase appropriate use.

Methods: An anonymous electronic survey was developed and actively distributed to behavioral health care practitioners (MD, DO, PA, NP, PharmD, RN, LCSW).

Microwave background temperature at a redshift of 6.34 from HO absorption.

Distortions of the observed cosmic microwave background provide a direct measurement of the microwave background temperature at redshifts from 0 to 1 (refs. ). Some additional background temperature estimates exist at redshifts from 1.
