Enhanced ultraviolet-B radiation (UV-B, 280–320 nm) is recognized as one of the environmental stress factors that cannot be neglected. Jasmonic acid (JA) is an important signaling molecule in a plant’s defense against biotic and abiotic stresses. To determine the role of exogenous JA in the resistance of wheat to stress from UV-B radiation, wheat seedlings(More)
In this paper, we report a simple, reliable and sensitive colourimetric visualization of melamine in milk products using citrate-stabilized gold nanoparticles (Au NPs). Upon exposure to ppb-level melamine, gold nanoparticle solution exhibits a highly sensitive colour change from red to blue and rapid aggregation kinetics within the initial 5 min, which can(More)
Problem Forest canopy height is essential information for many forest management activities and is also a critical parameter in models of ecosystem processes and in better quantifying the terrestrial carbon cycle [1, 2]. Several categories of methods are available to measure canopy height from remote sensing technology, one of which is the Polarimetric(More)
Forest aboveground biomass (AGB) was mapped throughout China using large footprint LiDAR waveform data from the Geoscience Laser Altimeter System (GLAS) onboard NASA's Ice, Cloud, and land Elevation Satellite (ICESat), Moderate Resolution Imaging Spectro-radiometer (MODIS) imagery and forest inventory data. The entire land of China was divided into seven(More)
Synthetic Aperture Radar is the only instrument that can provide consistent remote sensing data for south China with persistent cloud cover and rain. It is generally difficult to acquire specified optical remote sensing images for interpretation due to frequent cloud and fog covers in subtropical area of southeastern China. Land cover mapping and timely(More)
Nowadays, to make additional profits, revenue management system plays an important role for airline. This study presents a framework of airline revenue management decision support system. The system includes 3 sub-systems, interface, model management and database management which integrate OLTP and OLAP techniques. Several algorithms for flight demand(More)
Traditional models of flight demand forecasting put great emphasis on the relationship of data features between historical flights and current flights. However, these models are not suitable for the frequent changes of flight schedule, which is a situation we often face. To adapt to this situation, a forecasting model of flight demand cluster was presented.(More)
