Development and assessment of a hospital-led, community-partnering COVID-19 testing and prevention program for homeless and congregate living services in Toronto, Canada: a descriptive feasibility study.

Background: Outbreaks of SARS-CoV-2 in shelters and congregate living settings are a major concern because of overcrowding and because resident populations are often at high risk for infection. The objective of this study was to describe the development, implementation and assessment of the COVID-19 Community Response Team, a program that enabled Women's College Hospital in Toronto, Ontario, to work in partnership with shelters and congregate living settings to prevent outbreaks.

Methods: The Community Response Team, associated with Women's College Hospital, an academic ambulatory hospital, carried out mobile testing for SARS-CoV-2, supported outbreak management and prevention through ongoing onsite partnership with medical staff, and conducted infection prevention and control (IPC) training to shelter staff.

Measurement of Residual Stress and Young's Modulus on Micromachined Monocrystalline 3C-SiC Layers Grown on <111> and <100> Silicon.

3C-SiC is an emerging material for MEMS systems thanks to its outstanding mechanical properties (high Young's modulus and low density) that allow the device to be operated for a given geometry at higher frequency. The mechanical properties of this material depend strongly on the material quality, the defect density, and the stress. For this reason, the use of SiC in Si-based microelectromechanical system (MEMS) fabrication techniques has been very limited.

Experimental Demonstration of an Electrostatic Orbital Angular Momentum Sorter for Electron Beams.

The component of orbital angular momentum (OAM) in the propagation direction is one of the fundamental quantities of an electron wave function that describes its rotational symmetry and spatial chirality. Here, we demonstrate experimentally an electrostatic sorter that can be used to analyze the OAM states of electron beams in a transmission electron microscope. The device achieves postselection or sorting of OAM states after electron-material interactions, thereby allowing the study of new material properties such as the magnetic states of atoms.

It starts with a strong foundation: constructing collaborative interprofessional teams in primary health care.

The purpose of this qualitative study was to explore how team members experience and enact interprofessional teamwork in primary health care (PHC). Fifty-three participants (from eight teams), members of the Association of Family Health Teams of Ontario (AFHTO), were interviewed; interviews were audiotaped and transcribed verbatim. The data analyses used an iterative process with individual and team analysis.

Wide bandwidth fiber-optic ultrasound probe in MOMS technology: Preliminary signal processing results.

An ultrasonic probe consisting of two optical fiber-based miniaturized transducers for wideband ultrasound emission and detection is employed for the characterization of in vitro biological tissues. In the probe, ultrasound generation is obtained by thermoelastic emission from patterned carbon films in Micro-Opto-Mechanical-System (MOMS) devices mounted on the tip of an optical fiber, whereas acousto-optical detection is performed in a similar way by a miniaturized polymeric interferometer. The microprobe presents a wide, flat bandwidth that is a very attractive feature for ultrasonic investigation, especially for tissue characterization.
