A 1.2 Billion Pixel Human-Labeled Dataset for Data-Driven Classification of Coastal Environments.

The world's coastlines are spatially highly variable, coupled-human-natural systems that comprise a nested hierarchy of component landforms, ecosystems, and human interventions, each interacting over a range of space and time scales. Understanding and predicting coastline dynamics necessitates frequent observation from imaging sensors on remote sensing platforms. Machine Learning models that carry out supervised (i.

A multi-modal approach towards mining social media data during natural disasters - a case study of Hurricane Irma.

Streaming social media provides a real-time glimpse of extreme weather impacts. However, the volume of streaming data makes mining information a challenge for emergency managers, policy makers, and disciplinary scientists. Here we explore the effectiveness of data learned approaches to mine and filter information from streaming social media data from Hurricane Irma's landfall in Florida, USA.

Blind testing of shoreline evolution models.

Beaches around the world continuously adjust to daily and seasonal changes in wave and tide conditions, which are themselves changing over longer time-scales. Different approaches to predict multi-year shoreline evolution have been implemented; however, robust and reliable predictions of shoreline evolution are still problematic even in short-term scenarios (shorter than decadal). Here we show results of a modelling competition, where 19 numerical models (a mix of established shoreline models and machine learning techniques) were tested using data collected for Tairua beach, New Zealand with 18 years of daily averaged alongshore shoreline position and beach rotation (orientation) data obtained from a camera system.

Literature-based latitudinal distribution and possible range shifts of two US east coast dune grass species ( and ).

Previous work on the US Atlantic coast has generally shown that coastal foredunes are dominated by two dune grass species, (American beachgrass) and (sea oats). From Virginia northward, dominates, while is the dominant grass south of Virginia. Previous work suggests that these grasses influence the shape of coastal foredunes in species-specific ways, and that they respond differently to environmental stressors; thus, it is important to know which species dominates a given dune system.

Use of text messaging to enhance compliance with the accreditation council for graduate medical education resident duty hour requirements.

Purpose: Recently, the Accreditation Council for Graduate Medical Education (ACGME) has developed and enforced a complex set of regulations limiting resident duty hours (RDHs). One potential method to comply with these stringent regulations and better document resident work hours would be to use text message (TM)/short message service (SMS), allowing rapid, inexpensive, and interactive 2-way delivery of information. The purpose of this study was to document the successful implementation of TM to enhance compliance with the ACGME RDH regulations.

Critical care checklists, the Keystone Project, and the Office for Human Research Protections: a case for streamlining the approval process in quality-improvement research.

Checklists have been recently promulgated as a method to enhance patient safety and improve outcomes for critically ill patients. Specifically, recent work performed by researchers from the Johns Hopkins Medical Institutions has demonstrated that the addition of checklists to usual care in the intensive care unit is associated with a decrease in the incidence of catheter-related bloodstream infections. Initially evaluated at the institutional level, this effort has been successfully expanded to the state level as part of the Michigan Keystone Project.

The iCritical care podcast: a novel medium for critical care communication and education.

Podcasting is a recent creation combining old and new technologies allowing rapid, inexpensive delivery of media content (primarily audio) to the end user, both via the desktop environment and personal media players. The authors' group (the Society of Critical Care Medicine) saw the educational and communication potential for the podcasting concept, and have successfully designed and implemented the first podcast of a national medical society. As of this writing, there are an average of (mean +/- SD) 664 +/- 290 total downloads per podcast, and their podcast feed has been hit over 68,000 times in its first seven months.

Successful treatment of Bouveret syndrome using holmium: YAG laser lithotripsy.

Although gallstone disease is highly prevalent, cholelithiasis causing gallstone ileus is uncommon. Consideration has been given for nonoperative strategies to resolve obstruction due to the significant age and comorbidities afflicting this population. A 94-year-old man presented with a 5-day history of abdominal distension and tenderness.

Calcifying fibrous pseudotumor of the neck: diagnostic challenges of a rare benign lesion.

Neck masses, frequently encountered by physicians, comprise a vast range of diagnoses, with malignancy being the greatest concern. Calcifying fibrous pseudotumor (CFP) is a rare lesion with unknown pathogenesis, characterized pathologically by a predominance of abundant hyalinized collagenous tissue with focal lymphoplasmacytic infiltrate and psammomatous or dystrophic calcifications. We present the case of a 29-year-old woman who presented with a 4-cm left neck mass, accompanied by constitutional symptoms of vague weakness and lethargy.

Extensive stage small cell lung cancer presenting as an acute perforated appendix: case report and review of the literature.

Malignancies of the appendix are uncommon; a small subset of these lesions are actually metastatic cancers. In some rare cases, these lesions can cause obstruction, appendicitis, and perforation. M.
