The advent of media-sharing sites like Flickr has drastically increased the volume of community-contributed multimedia resources on the web. However, due to their magnitudes, these collections are increasingly difficult to understand, search and navigate. To tackle these issues, a novel search system, ContextSeer, is developed to improve search quality (by(More)
An 82-year-old man suffering from shortness of breath for more than 10 days, was diagnosed with acute heart failure, New York Heart Association functional class IV. Grade IV systolic murmur at the apex as well as grade II diastolic murmur over the left second in-tercostal space and engorged jugular veins were noted on presentation. Transthoracic(More)
UNLABELLED Variant angina presenting acute chest pain and ST elevation on electrocardiogram accounts for an underdiagnosed scenario in acute coronary syndrome and contributes to syncope as a consequence of ventricular arrhythmia. Here, we report a case of a 48-year-old man with a recent onset of chest pain and palpitations followed by syncope. Holter(More)
A 75-year-old man presented to our hospital with symptoms of fever, abdominal pain, intermittent hematemesis and melena for 2 days. The patient underwent stent-graft placement for a thoracic aortic aneurysm (TAA) 6 months prior to this presentation. Seven days ago, he suffered from dyspepsia; an upper gastrointestinal (UGI) endoscopy indicated a submucosal(More)
Satellite RNAs (satRNAs) are subviral agents that depend on cognate helper viruses for genome replication and encapsidation. Their negative impacts on helper viruses have been exploited to control plant viral diseases. SatBaMV is a commonly found satRNA associated with Bamboo mosaic virus (BaMV) that infects diverse bamboo species in the field. To(More)
An 82-year-old man presented to our emergency department complaining of shortness of breath over recent days. He had a medical history of hypertension, dilated cardiomyopathy, and chronic at-rial fibrillation. Electrocardiography showed atrial fibrillation with rapid ventricular rate. We carried out contrast-enhanced computed tomography due to his high(More)
Pulmonary hypertension is characterized by elevated pulmonary arterial pressure and secondary right ventricular failure. A thromboembolic occlusion of the proximal or distal pulmonary vasculature results in chronic thromboembolic pulmonary hypertension. We report an uncommon case that presented to our hospital with symptoms of dyspnea on exertion over 2(More)
This paper proposed using a unified model to characterize the motion variations along both the spatial and temporal domains. To this end, we estimate the motion quantities from the pixelwise normal flow and represent the motion distribution using two Gibbs models: temporal and spatial Gibbs models. We measure the potential values of the two Gibbs models by(More)
