While ultra-deep-submicron design presents increasingly difficult challenges for standard synchronous design practices, recent research in asynchronous design techniques is making asynchronous circuits an increasingly practical alternative. These challenges include the increasing pressure for low-power, the growing challenge of predicting increasing impact of wire load and delay, and the perfor...

Intracranial aneurysms have rarely been reported in association with complex partial seizures. We report five cases of complex partial seizures where aneurysms were found either accidentally or through investigations in these patients. MRI scans and angiograms revealed these aneurysms and in one patient several aneurysms were found. Four patients were treated with GDC coil embolisation with fol...

Just who is to count as an ‘academic’ and who not? What term best describes the people we are interested in? In some countries, it seems sufficient to use the term ‘professori...
