Clustering is a very well studied problem that attempts to group similar data points. Most traditional clustering algorithms assume that the data is provided without measurement error. Often, however, real world data sets have such errors and one can obtain estimates of these errors. We present a clustering method that incorporates information contained in(More)
Epilepsy is a chronic neurological disorder that can have profound physical, social and psychological consequences. We aimed to assess the clinical predictors of quality of life of people with epilepsy. We recruited 31 patients suffering from epilepsy in this cross-sectional study. Their clinical profile was recorded. Quality Of Life in Epilepsy (QOLIE-31)(More)
This study investigates the comparative changes in the sodium MRI signal and proton diffusion following treatment using a 9L rat glioma model to develop markers of earliest response to cancer therapy. Sodium MRI and proton diffusion mapping were performed on untreated (n = 5) and chemotherapy 1,3-bis(2-chloroethyl)-1-nitrosourea-treated rats (n = 5).(More)
Sensor Networks are highly vulnerable to attacks because, it consists of various resource-constrained devices and they communicate via wireless links. Establishment of pairwise keys between sensor nodes is used to realize many of the security services for Sensor Networks. Hence securely distributing keys among sensor nodes is a fundamental challenge in(More)
Internet Service providers (ISPs) are the building blocks for Internet. Due to huge demand of Internet by various business communities and individuals, ISPs are trying to meet the increasing traffic demand with improved utilization of existing resources and application of new technologies. Routing of data packets can affect network resource utilization. A(More)
PURPOSE Vascular endothelial growth factor (VEGF)-A is an important mediator of angiogenesis in almost all solid tumors. The aim of this study was to evaluate the effect of VEGF-A expression on tumor growth, perfusion, and chemotherapeutic efficacy in orthotopic 9L gliosarcomas. EXPERIMENTAL DESIGN Stable 9L cell lines underexpressing and overexpressing(More)
BACKGROUND Temporomandibular disorders (TMDs) are by far the most predominant condition affecting the temporomandibular joint (TMJ), however many patients have mild self-limiting symptoms and should not be referred for specialist care. The aim of this pilot study was to develop a simple, cost-effective management programme for TMDs using CD-ROM. 41 patients(More)
