Satellite and aerial platforms are critical in the deployment of global quantum communications networks. Currently, there remain significant challenges including operation during daytime and robustness to visibility limiting conditions. In this work we investigate, through simulation, the impact of visibility limiting conditions on low-Earth orbit CubeSat dimensioned satellites, small satellites and high-altitude platform implementations.

Background: International Classification of Diseases (ICD)-10 code specificity is important for detailed diagnostic documentation. Insufficient coding granularity in plastic surgery may hinder accurate clinical documentation, impacting education, research, and patient care. This study examines ICD-10 code modification efforts by plastic surgeons and plastic surgery organizations within the last decade, subsequently detailing the formal proposal process and highlighting potential areas where coding modifications may be explored.

- EMS clinicians handle traumatic pneumothoraxes, including simple ones that are less severe and tension pneumothoraxes that can lead to serious complications like shock.
- The most common treatment for tension pneumothorax in EMS is needle thoracostomy, but its frequent misapplication and low success rates have raised concerns about its effectiveness.
- The National Association of EMS Physicians conducted a literature review to create evidence-based recommendations for managing traumatic pneumothoraxes, addressing the need for proper decompression techniques and clarifying procedures for open pneumothoraxes.
Climbing the Research Ladder: A 25-year Analysis of K-to-R Grant Conversion among Plastic Surgeons.

Article Synopsis
- The study evaluates how effectively plastic surgeons transition from early career K grants to established R grants, particularly compared to other medical specialties.
- It found that plastic surgeons have lower initiation rates for K grants and a successful conversion rate of 52.9% to R grants, similar to other specialties.
- The research highlights that the quality of publications, as indicated by citation ratios, may positively influence successful grant conversions, suggesting that more focus on impactful research could help plastic surgeons secure more NIH funding.
The optical interfacing between a free-space channel and single-photon detectors (SPDs) can greatly impact the inherent performance of a free-space quantum key distribution receiver. Direct coupling to detectors creates engineering challenges, and a single-mode fiber requires adaptive optics. Using a multimode fiber (MMF) is common; however, larger core diameters limit the achievable bandwidth.
