Linear image deconvolution for radio-astronomy is an ill-posed problem. For this reason, a-priori knowledge is crucial for improving the performance of the deconvolution. In this paper we show that combining non-negativity constraints with an upper bound on the magnitude of each pixel in the image can significantly improve the image formation algorithm. We also show that the minimum variance distortionless...
What is known and Objective: Montelukast, a cysteinyl leukotriene receptor 1 antagonist, is safe and efficacious in patients with asthma. The mechanisms underlying the significant interpatient variability in response to montelukast are not clear but are believed to be, in part, because of genetic variability.
Methods: To examine the associations between polymorphisms in candidate genes in the leukotriene...
The Web-based lecture-scene playback system using the digital picture-card show has been studied to improve the educational quality of lectures with computer-aided slide presentations in universities. In this system, fine still images of lecture scenes, containing the lecturer, the blackboard, and the presentation screen, are periodically taken by a commercial digital photo camera, and the lecturer...
Computer-aided slide presentations have been commonly used at lectures in universities. To improve their educational quality, this paper presents an Web-based lecture scene playback system using the digital picture-card show for distance learning. In this system, fine still images of lecture scenes containing the lecturer, the blackboard, and the screen, are periodically taken by an off-the-shelf...
