In microbial ecology, the “everything is everywhere” hypothesis has long been controversial. In the present study, we performed data-mining for 18S rDNA sequences of glomeromycotan fungi in order to test this hypothesis. 18S rDNA sequences targeted using AM1–NS31 fragments were retrieved from GenBank, with a total of 1768 sequences collected from 34 sites worldwide. In total, 229, 330 and 518 operational...
In this paper, we use a novel way to research the piezoresistance coefficients of AlGaN/GaN HEFT affected by the changes of temperatures in the structure of micro-accelerometer. It is shown that saturation current of HEFT would decrease with the increasing temperature, which is about 0.028mA/°C. However, the device can work well at the temperature range of -50°C to 50°C, which indicates that it can...
