The decarboxylation mechanism of oxaloacetate catalyzed by transition metal ions M(?...?) (M=Cu, Zn, Co) has been studied using Density Functional Theory (DFT). The calculations show that the catalytic cycle contains two stages: the formation of oxaloacetate-M(?...?) complexes, and the cleavage of the...

Sepsis is a life-threatening organ dysfunction caused by a deregulated host response to infection, and is the most common cause of death in the intensive care unit. Although the pathogenesis of sepsis has made substantial progress, the current clinical treatment of sepsis is basically symptomatic treatment,...

In view of the current most based on Fourier transform domain method, its resist geometric attacks performance is very good, the embedded information is also big, but there are shearing attack ability is bad problems, and put forward a kind of based on singular value decomposition and discrete Fourier...

With modulus (KH = 0.89, SM = 2.42, IM = 1.70), substituting the sludge for the shale in the calculation of the cement burden, we studied the influence of different amount of sludge on the cement raw meal sintering, mineral composition, compression strength and the leaching value of heavy metal element....

Channel equalizer is a key component of WSN-OFDM (Wireless Sensor Networks Orthogonal Frequency Division Multiplexing) system. Traditional equalizer is mostly designed with LS algorithm, which comes with low precision in channel estimation. The previous LMMSE algorithm could reach a high accuracy, but...
