Ammonia-oxidizing bacteria and archaea (AOA and AOB) perform the rate-limiting step of nitrification, a biogeochemical process that controls the availability of inorganic nitrogen in terrestrial and aquatic ecosystems. We sought to investigate field values of AOA and AOB ammonia-uptake kinetics along with domain-level contributions to ammonia oxidation in temperate forest soils. To accomplish this...
The traditional glass drilling using mechanical processing and laser processing in air would produce many kinds of defects such as bugle, debris, crack and scorch. In this paper, we have applied the method of liquid-assisted laser processing (LALP) to reduce the temperature gradient, heat-affect zone region for achieving crack-free glass drilling. At the parameters of laser power 6 W, scanning speed...
The traditional glass forming using laser ablation in air would produce many kinds of defects such as bulge, debris, crack and scorch. In this paper, we have applied the method of PDMS assisted laser processing to reduce the temperature gradient, heat-affect zone region for achieving crack-free glass ablation. The laser power of 15 W, PDMS thickness of 150 μm and scanning speed of 228 and 342 mm/s...
A detailed RF modeling and analysis for the effect of the phase noise of the local oscillator (LO) on a 60-GHz wireless non-contact human vital-signal detection system has been developed. To model the effect of the LO phase noise on the remote detecting estimation of the desired breathing and heartbeat signals around 1 Hz, the Lorentzian spectrum is applied for the RF system simulation of detection...
