Communimetric screening tools help clinicians identify and communicate their patient's areas of need and the corresponding level of action. However, few tools exist to identify mental health (MH) and developmental needs in young children. We aimed to implement and evaluate a new communimetric MH and developmental screening tool for children under 6 (HEADS-ED Under 6) in a community MH agency in Ontario, Canada.

Coherent High-Frequency Axial Oscillations in a Partially Magnetized Direct Current Magnetron Discharge.

High-frequency oscillations are observed in a neon plasma of a direct current magnetron discharge. At low discharge currents, we see highly coherent 60 MHz fluctuations. Above a distinct current threshold, secondary 5-10 MHz fluctuations emerge in addition to turbulent fluctuations in the 60-100 MHz range.

Artificial intelligence in cosmetic dermatology: An update on current trends.

The use of artificial intelligence (AI) will soon be commonplace within the field of cosmetic dermatology. Current uses for AI in the discipline have focused on empowering patients to be more involved in treatment decisions with customizable skin care, augmented-reality applications, and at-home skin analysis tools. AI-driven skin analysis tools are also included in many dermatology practices with the development of three-dimensional facial reconstruction, including models for predicting clinical outcomes.

New and continuing physician-based outpatient mental health care among children and adolescents during the COVID-19 pandemic in Ontario, Canada: a population-based study.

Objective: To assess physician-based mental health care utilization during the COVID-19 pandemic among children and adolescents new to care and those already engaged with mental health services, and to evaluate differences by sociodemographic factors.

Study Design: We performed a population-based repeated cross-sectional study using linked health and administrative databases in Ontario, Canada among all children and adolescents 3-17 years. We examined outpatient visit rates per 1,000 population for mental health concerns for those new to care (no physician-based mental healthcare for ≥1 year) and those with continuing care needs (any physician-based mental healthcare <1 year) following onset of the pandemic.

Tunable non-reciprocal waveguide using spoof plasmon polariton coupling to a gaseous magnetoplasmon.

We experimentally demonstrate non-reciprocal (one-way) waveguiding in a microstrip transmission line tailored to support the propagation of spoof plasmon polaritons. Time-reversal symmetry is broken by coupling the microstrip fields to a magnetized gaseous plasma discharge column thereby exciting non-reciprocal magnetoplasmons at the interface between the plasma and a surrounding quartz envelope. The magnetic bias introduces asymmetry in the dispersion of the surface plasmon polaritons at the gaseous plasma-dielectric interface, resulting in a breaking of the bidirectionality of the wave propagation in the microstrip.
