The invention makes the generation of a low frequency error clock source for backscatter link frequency possible. The power consumption of the invention is very low such that the reading distance of a passive transponder is not harmed. Also the clock calibration process continuously conducted in t.....

Salinity and drought stresses posed a severe problem to agriculture worldwide. Both stresses will induce oxidative stress and cause damage to plant cells, resulting in retarded plant growth and consequently a reduction in crop yield. We identified a novel purple acid phosphatase (PAP) gene from so.....
