Analogue CMOS high-frequency continuouswavelet transform circuit
Electronics Letters, 1999 A 16-channel analog CMOS high-frequency continuous wavelet transform circuit has been realized. The circuit performs a time-frequency decomposition of a high-frequency input signal. A 100 MHz operating frequency, 45 MHz bandwidth, and 40 mW/channel power dissipation have been achieved using a 0.5 /spl mu/m CMOS process.

FEBS Letters, EarlyView.Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...
