High Resolution FPGA DPWM Based on Variable Clock Phase Shifting [PDF]
IEEE Transactions on Power Electronics, 2010 This paper proposes a very high resolution DPWM architecture that takes advantage of an FPGA advanced clock management capability: the fine phase shifting of the clock. This feature is available in almost every FPGA nowadays, allowing very small and programmable delays between the input and output clocks.

Intracerebral Hemorrhage in Autosomal Dominant Cerebral Arteriopathy With Subcortical Infarcts and Leukoencephalopathy. [PDF]
Eur J NeurolABSTRACT Background Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is the most common hereditary cerebral small vessel disease (CSVD). Intracerebral hemorrhage (ICH) is reported to be increasing in CADASIL patients from areas where the p.R544C mutation is prevalent (e.g., Jeju and Chinese Taiwan ...
