conclusions: in this study, a higher rate of more severe itp in recently vaccinated young children was observed in comparison with other probable etiologies. further investigations are needed to explain this finding. results: 51 patients were enrolled in this study (mean age = 3.86 ± 1.53 months; males = 32 [62.7%]). in 33 (64.7%) patients the platelets level was below 20000 /mm3. thrombocytope...

All living organisms are exposed to ionizing radiation comprising cosmic rays coming from outer space, terrestrial nuclides occurring in the earth’s crust, building materials, air, water and foods and in the human body itself. The exposures are constant and uniform for all individuals everywhere including the dose from ingestion of 40K in food. Cosmic rays are, more intense at higher alt...

A common method for real-time segmentation of moving regions in image sequences involves “background subtraction,” or thresholding the error between an estimate of the image without moving objects and the current image. The numerous approaches to this problem differ in the type of background model used and the procedure used to update the model. This paper discusses modeling each pixel as a mix...
