Diabetic Retinopathy (DR) is one of the major complications of diabetes mellitus and can cause blindness. The diagnosis of DR is performed by visual analysis of retinal images being exudates (fat deposits) the mains patterns traced by a specialist doctor. This paper presents a new method for DR detection in color retinal images. The proposed algorithm(More)
— Diabetic Retinopathy (DR) is one of the major complications of diabetes mellitus and can cause blindness. The diagnosis of DR is performed by visual analysis of retinal images, with exudates (fat deposits) being the main patterns traced by a specialist doctor. Thus, this paper proposes an algorithm for exudate detection in retinal images, whose(More)
Large-scale RNAi-based screens are a major technology, but require adequate prioritization and validation of candidate genes from the primary screen. In this work, we performed a large-scale pooled shRNA screen in mouse embryonic stem cells (ESCs) to discover genes associated with oxidative stress resistance and found several candidates. We then developed a(More)
This paper proposes an architecture to classify traffic flows of IP access networks, and signalize to hybrid optical network the most appropriate paradigm, Optical Circuit Switching (OCS) and Optical Burst Switching (OBS), to be used. The concept of software defined networks, more specifically the OpenFlow technology, was used to enable the architecture.(More)
