In this study, we present a hardware implementation of the conscience mechanism in Kohonen self-organizing maps. The proposed realization of the conscience mechanism is important to the functioning of the neural network as it eliminates so-called dead (inactive) neurons. As a result the network learning, the level quantization error can be reduced. The conscience mechanism and the Winner Take A...

Organizing Lobar Pneumonia is a rare form of Bronchiolitis Obliterans Organizing Pneumonia.  Herein, we report a rare case of organizing pneumonia involving lung, mediastinum and esophagus.  A 16-year-old girl was referred to our center with clinical signs and symptoms of dysphagia and weight loss.  The main abnormal radiologic and endoscopic findings were stricture of the lower third of esopha...

T-cell nonresponsiveness is a critical factor in immune escape and myeloid-derived suppressor cells play a major role in organizing this phenomenon. Recent findings indicate that myeloid-derived suppressor cells can induce antigen-specific CD8(+) T-cell tolerance through a posttranslation mechanism which involves modification (nitration) of CD8 and the T-cell receptor itself on the T-cell surfa...
