A down-converting mixer fabricated with 0.18μm RF CMOS technology is designed for OFDM-UWB applications.Differing from conventional Gilbert cell topology,a differential topology is proposed and applied in order to reduce the noise contribution and disturbance from the large signal of the local oscillation,as well as to lower the DC consumption of the mixer.

On the basis of 414 soil profiles from 14 provinces, it was found that soil organic carbon, differing from soil inorganic carbon and other elements, has a trend of exponentially decreasing with depth. Integral analysis of exponential curve contrasting with the linear model affords the uncertainties of linear model and exponential model for carbon storage calculation. It was found that the integration of TOC with the linear model has errors between +20% to +100%, much higher than that of the exponential model (-10% to +20%).

The ORF2 gene is the most important protein-code gene for porcine circovirus, and is the main gene differing porcine circovirus typel from porcine circovirus type2 (PCV2). To construct a specific PCR detecting method, we designed a pair of primers to amplify a partial fragment of ORF2 gene from PCV2, referring to fifteen strains complete genome published in Genbank. The PCR product was about 0.67kb in size detected by gelose gel electrophoresis.
