We propose a scalable architecture for shared virtual environments , named SpaceFusion, which is designed to provide practical , large-scale w-vices on the Internet. Here, the world is divided into smaller chunks, called regions, and a region plays a centrat role to obtain scalability and to realize the notion of Fusion. SpaceFuswn clients can get(More)
To reveal a pathway by which psychological/physical stresses influence host defense capability, responses to immobilization stress in mice were investigated, focusing on a multifunctional cytokine, interleukin-18 (IL-18). Immobilization stress induced interleukin-18 accumulation in plasma and in the adrenal gland. Inhibition on ACTH resulted in suppressed(More)
Spontaneously diabetic Torii (SDT) rats were established from Sprague-Dawley (SD) rat and are used as an animal model of type 2 diabetes mellitus. In the present study, the mechanism of the development of injury in the pancreas of these rats was examined focusing on the role of monocytes/macrophages. The number of lymphocytes and monocytes in the(More)
A role of IL-18 in the induction of gastric lesions by water immersion and restraint stress (WRS) was investigated. When wild-type BALB/c mice were exposed to WRS, levels of IL-18 in the serum and stomach increased rapidly with the development of acute gastric lesions. In IL-18-deficient mice [IL-18 knockout (KO) mice] similarly exposed to WRS, no gastric(More)
In distributed data stream processing, a program made of multiple queries can be parallelized by partitioning input streams according to the values of specific attributes, or partitioning keys. Applying different partitioning keys to different queries requires re-partitioning intermediary streams, causing extra communication and reduced throughput.(More)
Dramatic increases in computing power and network speed, along with advances in sensing technology, have broadened the range of devices that can connect to the Internet. Large quantities of diverse, time-sequenced data are flowing in from the Web and countless sensors, and there is a strong demand to rapidly and efficiently extract any valuable information(More)
We have developed the Grid Service Platform (GSP), which is a grid middleware for telecom carriers. GSP can support not only non-interactive batch style services, but also interactive real-time services. Moreover, GSP attains autonomous resource sharing between services based on the priority of each service. We conducted a field trial of GSP on a testbed(More)
BACKGROUND We evaluated the side effects of bisphosphonate (BP) on tooth extraction socket healing in spontaneously diabetic Torii (SDT) rats, an established model of non-obese type 2 diabetes mellitus, to develop an animal model of BP-related osteonecrosis of the jaws (BRONJ). MATERIALS AND METHODS Male Sprague-Dawley (SD) rats and SDT rats were randomly(More)
