Quantitative DNA-DNA hybridization to measure the genetic distances among bacterial species is indispensable for taxonomical determination. In the current studies, we developed a method to determine bacterial DNA relatedness on a glass microarray. Reference DNAs representing a total 93 species of Enterobacteriaceae were arrayed on a glass microplate, and(More)
This paper presents a high power, high efficiency RF power amplifier using GaN on Si heterojunction field effect transistor (HFET) designed using waveform engineering. To investigate the high efficiency operation of the GaN HFET, waveform engineering, employing harmonic active load-pull measurements is conducted, yielding 79W output power and 73.9% drain(More)
We have recognized marked effectiveness for intermittent claudication with low-density lipoprotein (LDL) apheresis in two cases of arteriosclerosis obliterans (ASO). The Case 1 was a 73-year-old man with intermittent claudication of both lower extremities (Fontaine class II), digital subtraction angiography (DSA) revealed complete obstruction of the left(More)
