In Programming by Example, the system records actions performed by a user in the interface, and produces a generalized program that can be used later in analogous examples. A key issue is how to describe the actions and objects selected by the user, which determines what kind of generalizations will be possible. When the user selects graphical objects on(More)
Pixel Data Access is an interprocess communication technique that enables users of graphical user interfaces to automate certain tasks. By accessing the contents of the display buffer, users can search for pixel representations of interface elements, and then initiate actions such as mouse clicks and keyboard entries. While this technique has limitations it(More)
PURPOSE To determine the optimal duration of preoperative chemotherapy to further increase the proportion of stage I tumors by comparison of two regimens in the treatment of patients older than 6 months who have unilateral Wilms' tumor. PATIENTS AND METHODS Eligible patients (n = 382) initially received four weekly doses of vincristine (VCR) and two(More)
Lung ischemia-reperfusion (I-R) is an important model of oxidant-mediated acute lung and vascular injury. Heme oxygenase-1 (HO-1) is a cytoprotective gene that is markedly induced by lung I-R injury. HO-1 mRNA is increased in mouse lung after 30 min of lung hilar clamping (ischemia) followed by 2-6 h of unclamping (reperfusion) compared with control mice.(More)

To evaluate the morphologic characteristics and frequency of thymic enlargement in Hodgkin disease, the initial and follow-up computed tomographic (CT) scans of 43 patients with newly diagnosed Hodgkin lymphoma were retrospectively analyzed. Sonograms of the thymic region in 21 patients were also available and were compared with the CT scans. Initial CT(More)
PURPOSE To determine the effectiveness of endovascular brachytherapy in the prevention of restenosis in recurrent versus de novo femoropopliteal lesions. MATERIALS AND METHODS Ethics committee approval and patient informed consent were obtained. After they had undergone femoropopliteal angioplasty, 199 patients (mean age, 71.9 years +/- 9.6; 115 men, 84(More)
Virtualization promises to overcome the weaknesses of the current Internet and to act as a torch bearer technology for enabling innovative network architectures. However, a fundamental problem in instantiation of Virtual Networks (VNs) is an optimal allocation of resources offered by a physical IP network. In order to solve this NP-hard problem, heuristics(More)
