We present the Cloud Operating System (COS), a middleware framework to support autonomous workload elasticity and scalability based on application-level migration as a reconfiguration strategy. While other scalable frameworks (e.g., MapReduce or Google App Engine) force application developers to write programs following specific APIs, COS provides(More)
A case of heterotopic gastric mucosa in the fundus of the gallbladder is reported. A 23-year-old man, who had been healthy and asymptomatic, visited our hospital because of abnormal findings in a liver enzyme test given during a routine health screening. Ultrasonography demonstrated a highly echogenic polypoid mass in the fundus of the gallbladder. The(More)
Carbocisteine is a mucoregulatory drug normalizing sialic acid and fucose contents in mucins through the regulation of glycosyltransferase activities. Tumor necrosis factor (TNF)-alpha-induced overexpression of sialyl-Lewis x epitopes, containing sialic acid and fucose, in mucins were previously reported to be regulated by glycosyltransferase mRNAs(More)
Cloud computing's pay-per-use model greatly reduces upfront cost and also enables on-demand scalability as service demand grows or shrinks. Hybrid clouds are an attractive option in terms of cost benefit, however, without proper elastic resource management, computational resources could be over-provisioned or under-provisioned, resulting in wasting money or(More)
-This paper proposes a novel architecture for DTV (Digital TV) using middleware based on UPnPTM (Universal Plug and Play) and DLNA (Digital Living Networking Alliance) to enable interoperability with a variety of digital CE devices supporting content of diverse formats transported over IP (Internet Protocol) and IEEE 1394. Additionally, content metadata,(More)
A 35-year-old woman was referred to our hospital for investigation of lower abdominal pain and a feeling of fullness. At her first consultation, a transvaginal ultrasonography (US) revealed a homogeneous cystic mass in the lower abdomen. Over a period of 8 months the US findings of the content of this mass changed from fine and faint internal echoes to(More)
BACKGROUND Human obstructive airway diseases are histopathologically characterized by inflammatory cell infiltration, goblet cell hyperplasia, and mucus hypersecretion in airways. We prepared a rat model of airway injury by exposure of sulfur dioxide (SO2) and then evaluated the effects of S-carboxymethylcysteine (S-CMC), a mucoregulant. METHODS Rats were(More)
A very rare case of adenomyoma of the common hepatic duct is described. A 54-year-old woman was admitted with impending obstructive jaundice secondary to adenomyoma of the common hepatic duct. Our impression, formulated from her clinical presentation, endoscopic investigations, and biochemical and radiological findings, was a cancer of the proximal common(More)
During a 10-year period (1986–1995), 59 of 538 patients with early gastric cancer (11.0%) had the superficial spreading type of gastric cancer. We attempted to elucidate the clinicopathological features and investigated the influence of those features on surgical procedures and patient prognoses. Methods. These 59 superficial spreading lesions were analyzed(More)
