Air Quality Prediction Based on Singular Spectrum Analysis and Artificial Neural Networks.

Singular spectrum analysis is a powerful nonparametric technique used to decompose the original time series into a set of components that can be interpreted as trend, seasonal, and noise. For their part, neural networks are a family of information-processing techniques capable of approximating highly nonlinear functions. This study proposes to improve the precision in the prediction of air quality.

The Historical Case for a Strong and Diverse Neurology Clerkship Leadership Team.

The role of the clerkship director has evolved significantly over the past century and now requires a diverse range of skills to meet the rigorous standards set by national accrediting bodies such as the Liaison Committee on Medical Education. We conducted a historical exploration, spanning the past 43 years, of the educational practices in the Neurology Department at Johns Hopkins University School of Medicine. We learned that no entity is responsible for documenting the history of the clerkship.

Interprofessional Collaboration and Patient/Family Engagement on Rounds in a Comprehensive Stroke Center: A Mixed-Methods Study.

Background And Objectives: Daily rounds provide an opportunity for interprofessional collaboration and patient/family engagement, which are critical to stroke care. As part of a quality improvement program, we conducted a baseline assessment to examine interprofessional collaboration and patient/family engagement during the current rounding process in a 12-bed comprehensive stroke center. Findings from the baseline assessment will be used to inform the development, implementation, and evaluation of a new rounding model.

How to Easily Depolymerize Polyurethane Foam Wastes by Superbase Catalysts in Ionic Liquids Below 100 °C.

This study introduces a novel and sustainable approach using Ionic Liquids (ILs) as a non-innocent solvent that enhances the performance of the basic catalysts to depolymerize polyurethane foam wastes (PUFWs) through hydrolysis, alcoholysis or aminolysis under mild conditions. The system is stable, fully recoverable, and reusable. Hydrolysis of PUFWs can occur in just 2 minutes at 95-98 °C, producing a white polyol that is easily separated and reused in new polyurethane synthesis.
