Introduction: We sought to understand the impact of locum tenens surgeons on pediatric surgical care delivery.
Methods: We conducted a cross-sectional survey of Children's Hospital Association pediatric surgical practices. Anonymous electronic surveys were used to investigate locum tenens utilization, primary reason for use, limitations on clinical activities, and variations in practice standards or quality.
Purpose: Keratin contamination is a common problem in mass spectrometry proteomic analyses, particularly in bottom-up mass spectrometry. The purpose of this study was to determine the protein contaminants introduced during the proteomic analysis of tear fluid.
Methods: Human tear fluid samples were collected using Schirmer strips.
SARS-CoV-2 variants are mainly defined by mutations in their spike. It is therefore critical to understand how the evolutionary trajectories of spike affect virus phenotypes. So far, it has been challenging to comprehensively compare the many spikes that emerged during the pandemic in a single experimental platform.

- Lake Michigan's nearshore regions, influenced significantly by nearby rivers, show total phosphorus (TP) concentrations exceeding the GLWQA's target of 7 μg L, raising concerns about nutrient-related issues.
- A monitoring program utilizing phosphorus-based models linked to hydrodynamic models was implemented to assess these nearshore conditions, revealing variability in TP concentrations due to the area's dynamic nature.
- The study found that while model predictions varied, they successfully illustrated temporal and spatial trends, indicating that hydrodynamics and river loads critically influence TP levels, thereby making the TP model a valuable tool for future assessments.
Electrochemically-formed disordered rock salt compounds are an emerging class of Li-ion electrode materials for fast-charging energy storage. However, the specific factors that govern the formation process and the resulting charge storage performance are not well understood. Here, we characterize the transformation mechanism and charge storage properties of an electrochemically-formed disordered rock salt from VMoO (VMO).
