Controlling Inputter Variability in Vignette Studies Assessing Web-Based Symptom Checkers: Evaluation of Current Practice and Recommendations for Isolated Accuracy Metrics.

Background: The rapid growth of web-based symptom checkers (SCs) is not matched by advances in quality assurance. Currently, there are no widely accepted criteria assessing SCs' performance. Vignette studies are widely used to evaluate SCs, measuring the accuracy of outcome.

Patient reported satisfaction levels with the use of telemedicine for general surgery-A systematic review of randomized control trials.

Background: As healthcare continues to evolve in the wake of COVID-19 pandemic, surgeons are presented with the opportunity to integrate telemedicine into healthcare in tandem with in-person consultations. We aimed to perform a systematic review of randomized controlled trials to assess patient satisfaction with telemedicine interventions in general surgery.

Methods: A systematic review was performed in accordance to the PRISMA guidelines.

Environmental Gating and Galvanic Effects in Single Crystals of Organic-Inorganic Halide Perovskites.

Understanding the impact of environmental gaseous on the surface of organometal halide perovskites (OMHPs) couples to the electronic and ionic transport is critically important. Here, we explore the transport behavior and origins of the gas sensitivity in MAPbBr single crystals (SCs) devices using impedance spectroscopy and current relaxation measurements. Strong resistive response occurs when crystals are exposed to different environments.

Electrode quenching control for highly efficient CsPbBr perovskite light-emitting diodes via surface plasmon resonance and enhanced hole injection by Au nanoparticles.

Compared to organic-inorganic hybrid metal halide perovskites, all-inorganic cesium lead halides (e.g, CsPbBr) hold greater promise in being emissive materials for light-emitting diodes owing to their superior optoelectronic properties as well as their higher stabilities. However, there is still considerable potential for breakthroughs in the current efficiency of CsPbBr perovskite light-emitting diodes (PeLEDs).

Soccer-specific video simulation for improving movement assessment.

The improvement of ecological validity of laboratory research studies has recently come to the forefront of technology with virtual reality scenarios. The purpose of this study was to assess differences between unanticipated and anticipated lower extremity biomechanics while performing a sidestep cutting task. A visualization software was developed for this purpose, which would recreate a soccer game situation for use in a laboratory setting.
