Microorganisms decompose organic substrates to obtain energy. This process releases carbon dioxide (CO2) and is the main cause of soil carbon release in terrestrial ecosystems. Fluctuations in microbial composition significantly affect net CO2 emissions in forests. Because factors are cross-correlated, addressing how they affect soil respiration (Rs), both(More)
The method of fault diagnosis of rolling bearings based on wavelet packet transform and support vector machine is presented. The key to fault bearings diagnosis is feature extracting and feature classifying. Wavelet packet transform, as a new technique of signal processing, possesses excellent characteristic of time-frequency localization and is suitable(More)
A corrosion sensor for monitoring the corrosion state of cover mortar was developed. The sensor was tested in cement mortar, with and without the addition of chloride to simulate the adverse effects of chloride-contaminated environmental conditions on concrete structures. In brief, a linear polarization resistance method combined with an embeddable(More)
Capsaicin has multiple pharmacological activities including antioxidant, anticancer, and anti-inflammatory activities. However, its clinical application is limited due to its poor aqueous solubility, gastric irritation, and low oral bioavailability. This research was aimed at preparing sustained-release matrix pellets of capsaicin to enhance its oral(More)
It is conducive to understand the movement of the dummy, the analysis of dummy injury curves and restraint system matching by studying on the trajectory of dummies. By viewing the crash video is difficult to quantitative analysis of dummy motion, so how to get the dummy trajectory through the test data is the urgent thing to solve the problem for engineers.(More)
BACKGROUND Pertussis is highly contagious; thus, prompt identification of cases is essential to control outbreaks. Clinicians experienced with the disease can easily identify classic cases, where patients have bursts of rapid coughing followed by gasps, and a characteristic whooping sound. However, many clinicians have never seen a case, and thus may miss(More)
We report synchronization and amplitude death phenomenon in identical time-delay chaotic systems. Theoretical analysis and numerical simulations show that complete synchronization, antisynchronization, and amplitude death are induced simultaneously in different state variables of an infinitedimensional response system. It overcomes some limitations of the(More)
