Positron Emission Tomography (PET) historically has major clinical and preclinical applications in cancerous oncology, neurology, and cardiovascular diseases. Recently, in a new direction, an application specific PET system is being developed at Thomas Jefferson National Accelerator Facility (Jefferson Lab) in collaboration with Duke University, University of Maryland at Baltimore (UMAB), and West...
We have developed a very high channel density custom A/D converter module for the drift chamber readout requirements of the Glue-X detector at Jefferson Lab Hall-D. This 6U VME64× module has 72 channels, including a low noise differential line receiver, cable frequency response equalization, and signal shaping with a 5th order filter. The signals are digitized at 125 MSPS with an assembly option for...
An immune-inspired danger theory model based on fuzzy set was proposed in this article. In the model the concept of fuzzy set and degree of membership are presented in the foundation of the "danger" definition in artificial immune system. By carrying on the computation to the degree of danger, it makes the organism to apperceive the danger and simultaneously to make a strategy efficiently...
