The Service-Oriented Computing (SOC) paradigm is allowing computer systems to interact with each other in new ways. According to the literature, SOC allows composition of distributed applications free from their platform and thus reduces the cost of such compositions and makes them easier and faster to develop. Currently web services are the most widely(More)
Service-oriented architecture (SOA) is gaining momentum as an emerging distributed system architecture for business-to-business collaborations. This momentum can be observed in both industry and academic research. SOA presents new challenges and opportunities for testing and verification, leading to an upsurge in research. This paper surveys the previous(More)
Runtime testing cost caused by service invocations is considered as one of the major limitations in Service-centric System Testing (ScST). Unfortunately, most of the existing work cannot achieve cost reduction at runtime as they perform offline testing. In this paper, we introduce a novel cost-aware pareto optimal test suite minimisation approach for ScST(More)
BACKGROUND The phosphatidylinositol 3'-kinase/Akt (PI3K/Akt) pathway is a key regulator for HER2- overexpressing breast cancer, but data about whether activation of PI3K/Akt is associated with poor prognosis and resistance to trastuzumab therapy is controversial. In this study we investigated predictive and prognostic significance of expression of p27, Akt,(More)
UNLABELLED Approximately 10%-20% of all systemic lymphomas have central nervous system (CNS) involvement, which has been correlated to a worsened prognosis. It is well known that secondary involvement of the adrenal glands may occur in up to 25% of patients during the course of diffuse lymphoma. Primary adrenal lymphoma (PAL), however, is a different(More)
Although gynecomastia is a well-defined paraneoplastic syndrome in patients with non-small cell lung cancer, the association with pleomorphic carcinoma has not been reported. A 50-yr-old man presented with bilateral gynecomastia and elevated serum beta-human chorionic gonadotropin (βhCG) level. Chest tomography showed a mass in the right middle lobe. Right(More)
