Classification decision tree algorithms are used extensively for data mining in many domains such as retail target marketing, fraud detection, etc. Highly parallel algorithms for constructing classification decision trees are desirable for dealing with large data sets in reasonable amount of time. Algorithms for building classification decision trees have a(More)
This paper addresses the issue of reliable transport of emerging data services in Ethernet over SONET (EoS) networks that require protection guarantees beyond standard best effort delivery. We argue that the current consensus of using Ethernet spanning tree and a SONET 1+1 protection, while providing reliability, is an inefficient use of resources. Instead,(More)
The virtual concatenation protocol in SONET/SDH has ushered in a novel routing paradigm that enables a circuit to be "split" and routed over multiple paths. However, this diverse routing causes differential delay among the paths which can impact service if not accounted for in the routing. In this paper, we introduce the differential delay aware routing(More)
Breast cancer is fast emerging as the leading cancer amongst females, especially in younger age group in India; a large proportion of these tumors are often aggressive and ER and/or PR negative. Promoter methylation of genes involved in DNA repair and hormonal regulation may, in part, account for this behavior. To test this hypothesis methylation status of(More)
AIMS The clinical relevance of frequent methylation of CpG islands of key cancer genes in breast cancer is being increasingly recognized. Our study aimed to evaluate the promoter methylation status of DNA repair genes-BRCA1MGMT and GSTP1 in tumor and circulating DNA of invasive ductal breast carcinoma patients. MAIN METHODS Methylation-specific PCR was(More)
UNLABELLED This prospective cohort study was conducted to find the role of tumor neovascularization in skin melanoma measured by preoperative Doppler ultrasound flowmetry in determining the 15-year outcome. SETTING Department of Surgery, University of Wales College of Medicine, Cardiff, UK. Seventy-one primary melanomas in 67 patients were studied with a(More)
OBJECTIVES The objective of this study was to determine the concordance of promoter methylation of stratifin, ERalpha and PR in tumor and circulating DNA in breast cancer patients and their association with clinicopathological parameters and disease prognosis. DESIGN AND METHODS Methylation specific PCR were carried out to investigate the promoter(More)
Cancers of the breast, uterine cervix, and lip or oral cavity are three of the most common malignancies in India. Together, they account for about 34% of more than 1 million individuals diagnosed with cancer in India each year. At each of these cancer sites, tumours are detectable at early stages when they are most likely to be cured with standard treatment(More)
Breast pain or mastalgia is the common symptom in the breast. The two most common concerns of patients presenting with mastalgia are: the fear that breast pain is a symptom of breast cancer and the presence of severe pain that affects a woman's quality of life. Breast pain requires thorough assessment and should be investigated in the same manner as any(More)
Maspin is a serine protease inhibitor with tumor-suppressor activity. Maspin can suppress tumor growth and metastasis in vivo and tumor cell motility and invasion in vitro. Previous studies indicate that the loss of Maspin expression is closely linked to aberrant methylation of the Maspin promoter. We examined the promoter methylation status of Maspin in(More)
