LocationSpark: In-memory Distributed Spatial Query Processing and Optimization.

Due to the ubiquity of spatial data applications and the large amounts of spatial data that these applications generate and process, there is a pressing need for scalable spatial query processing. In this paper, we present new techniques for spatial query processing and optimization in an in-memory and distributed setup to address scalability. More specifically, we introduce new techniques for handling query skew that commonly happens in practice, and minimizes communication costs accordingly.

Comparison of intubation success of video laryngoscopy versus direct laryngoscopy in the difficult airway using high-fidelity simulation.

Introduction: A number of devices, including video laryngoscopy, are used to aid in managing difficult airways. The goal of this study was to compare timing and success of video laryngoscopy to standard laryngoscopic intubation using a simulation mannequin in normal and difficult airway scenarios.

Methods: Residents and attending physicians of a PGY 2-4 emergency medicine residency program participated.

Diagnosis and management of the acute red eye.

The red eye is one of the most frequent presenting complaints in the emergency department setting. A wide spectrum of disease processes may present as a red eye, ranging from benign self-limiting etiologies to serious vision-threatening ones. The emergency physician must be adept at recognizing "red flags" from the history and physical examination that necessitate immediate treatment and referral.
