Integrational plasmid technology has been used to disrupt metabolic pathways leading to acetate and butyrate formation in Clostridium acetobutylicum ATCC 824. Non-replicative plasmid constructs, containing either clostridial phosphotransacetylase (pta) or butyrate kinase (buk) gene fragments, were integrated into homologous regions on the chromosome.(More)
An ideal Software Defined Radio (SDR) requires a reconfigurable, intergrated, widely-frequency-tunable transceiver able to support different RX/TX duplex schemes. Here we present an integrated transceiver capable of supporting both TDD and FDD operation with >25dB integrated RX-TX isolation from 0.3-1.6GHz without any off-chip switches or filters. The(More)
