Magnetic resonance imaging (MRI) is a useful method for diagnosis of tumours in human brain. In this work, MRI images have been analysed to detect the regions containing tumour and classify these into three different categories: meningioma, glioma, pituitary. Deep learning relatively recent powerful image classification tasks. Therefore, faster Region-based Convolutional Neural Networks (faster R-CNN), deep method, has utilized implemented via TensorFlow library study. A publicly available...

We investigate the effects of saturation boundary on small-x evolution at next-to-leading order accuracy and beyond. demonstrate that instabilities BFKL are not cured by presence boundary. This indicates a resummation higher corrections is therefore needed also for nonlinear evolution. The renormalization group improved resummed equation in investigated, corresponding scale extracted. A significant reduction found, we observe onset delayed to rapidities. seems be related characteristic...
