A reconfigurable cipher chip for accelerating DES is described, 3DES and AES computations that demand high performance and flexibility to accommodate large numbers of secure connections with heterogeneous clients. To obtain high throughput, we analyze the feasibility of high-speed reconfigurable design and find the key parameters affecting throughput. Then, the corresponding design, which includes the reconfignration analysis of algorithms, the design of reconfignrable processing units and a new reconfignrable architecture based on pipeline and parallel structure, are proposed. The implementation results show that the opcrating fiequency is 110 MHz and the throughput rate is 7 Gbps for DES, 2.3 Gbps for 3 DES and 1.4 Gbps for AES. Compared with the similar existing implementations, our design can achieve a higher performance.

Motivated by the application of （Ti, Al）N alloy compound in the coating layer, the ternary phase diagram of Ti-Al-N was analyzed by the calculation of the phase diagram （CALPHAD） technique. The isothermal sections of the Ti-Al-N ternary system were constructed and compared with the literature experimental results. The thermodynamic parameters of the Ti-Al-N ternary system and the related Ti-N and Al-N binary systems were adopted from literatures, whereas, those of the Ti-Al binary from the literatures were adjusted according to both the ternary and the binary phase equilibria. The consistency between the calculated results and the experimental data shows that considering the ternary thermodynamic relationship, the adjustments to the thermodynamic parameters of the related binaries are necessary.

To confirm the optimum cultivation conditions for analyzing lactic acid bacterial communities and to provide the cultivation foundation for lactic acid bacterial communities that were used to convert straw into fodder, fermented rice straw was inoculated into 13 different broths. After 48 h of cultivation, pH values, volatile products, and microbial diversity were analyzed. Except for LAB broth, the pH values of the other broths could decrease to approximately 4.5. GC/MS analysis showed that lactic acid in Tomato MRS broth, MRS broth, LAB broth, and Tomato juice broth was higher than that in the other broths. DNA concentration analysis showed that the counts of microbes in Tomato MRS broth were 2.5 times of those in other broths and that tomato juice favored the reproduction of the microbes. Denaturing gradient gel electrophoresis （DGGE） analysis showed that the number of lactic acid bacterial species in HYA broth, Tomato juice broth, and Tomato MRS broth were higher than those in the other broths.

Based on the phase equilibrium calculation of the Ti-Al-N ternary system, the interfacial reactions and the phase formation sequences between different types of joints, （Ti matrix）/（AlN particles）, （Ti particles）/（AlN plate）, and （Ti plate）/（AlN plate）, were analyzed theoretically under the reported experimental conditions, Different phase formation sequences for the three kinds of Ti/AlN joints were obtained, It proved that the different phase sequences of both the phase formation sequences and the apparent spatial phase sequences are dominated by the relative amounts and the distribution of the two pairs in the diffusion couples, The theoretical prediction can explain the experimental observations well.

Willa Cather （1873-1947） is one of the greatest women writers in the history of American literature, whose reputation centers on her novels about celebrating pioneer immigrants on Nebraska prairie and the American southwest. For long Willa Cather＇s pioneer works have gained great critical acclaim and have been interpreted from different perspectives such as mythicism, romanticism, and feminism. This paper, interpreting Willa C ather＇ s classical pioneer works of the three periods from the 1920s to the 1930s-My A ntonia （ 1918）, A Lost Lady （1923）, and ＂Neighbor Rosicky＂（1930）, is devoted to making a full exploration into the evolution of her ecological thoughts from an ecofeminist perspective. In Willa Cather＇s three pioneer works of different creative stages, she deliberately constructs three eco-worlds as a standard of ecological harmony. In her three eco-worlds, Willa Cather not only investigates the relationship between man and nature, but also involves androcentrism, patriarchy, and other ecofeminist topics. Willa Cather＇s ecological views have undergone changes in her representation of three successive phrases. To interpret Willa Cather＇s pioneer works from the perspective of ecofeminism can provide a deeper comprehension about her works and her ecological thoughts for the world.

In this study, the insecticidal active substance of the fruiting body of Paecilomyces cicadae （Miquel） Samson that can kill the larvae of Plutella xylostella （Lepidoptera： Plutellidae） was isolated and purified by combined separation with biology experiments for the first time. By means of bioactive guided isolation of 40% ethanol-H2O, dichloromethane, ethyl acetate, n-butyl ethanol, macroporous adsorption resin column, high performance liquid chromatography, and sephadex A-20 column, the insecticidal active compound was purified,and a white powder compound was obtained. The compound was active against the third instar larvae ofP. xylostella in 24, 48, and 72 h at the concentration of 10.0 mg mL-1 with a corrective mortality of （95.1 ± 1.8）, （97.7 ± 1.6）, and （99.1 ± 1.7）%, respectively. The compound was strongly sensitive to the larvae. It was stable at acid environment, and was not sensitive to pepsin, and other chracteristics were studied.

Background Vascular access （VA） dysfunction is a major clinical complication in the hemodialysis population and has a direct effect on dialysis outcome. This study was conducted to explore the role of microinflammation in the VA dysfunction in maintenance hemodialysis patients. Methods Forty-seven patients （male 35 and female 12） receiving maintenance hemodialysis were included for this study. They were divided into three groups： group 1 （n=15）, patients with initial hemodialysis and new arteriovenous fistula （AVF）; group 2 （n=18）, patients treated with hemodialysis for long term with well-functional VA; group 3 （n=14）, maintenance hemodialysis patients with VA dysfunction. Biochemical parameters and serum tumor necrosis factor-α （TNF-α）, interleukin 6 （IL-6） and monocyte chemoattractant protein-1 （MCP-1） were determined. High-sensitivity C-reactive protein （hs-CRP） was determined by latex-enhanced immuno-nephelometric method. Tissues of radial artery were taken from group 1 and group 3 for the histological study. Expression of CD68 and MCP-1 in the radial artery was determined by immunohistochemistry. Results Serum hs-CRP in group 3 was significantly higher than those in group 1 and group 2 （（7.40±2.42） mg/L vs （4.21±1.62） mg/L and （5.04±3.65） mg/L, P 〈0.01 and P 〈0.05, respectively）. Serum TNF-α in group 3 was significantly higher than those in group 1 and group 2 （（64.03±9.29） pg/ml vs （54.69±12.39） pg/ml and （54.05±7.68） pg/ml, P 〈0.05 and P 〈0.01, respectively）. Serum IL-6 in group 3 was also significantly higher than those in group 1 and group 2 （（70.09±14.53） pg/ml vs （56.43±10.11） pg/ml and （60.77±9.70） pg/ml, P 〈0.01 and P 〈0.05, respectively）. Patients in group 3 had a thicker internal layer of vessels than in group 1 （（0.356±0.056） mm vs （0.111±0.021） mm, P 〈0.01）. Expression of CD68 and MCP-1 in the fistula vessel walls in group 3 were much higher than those in group 1 （P 〈0.01）. Moreover, serum hs-CRP level was positively correlated with the neointi

Monthly difference of the chemical composition of oyster cultured along the eastern coast of Shandong Province was analyzed. The components analyzed included glycogen, fatty acid and free amino acid （FAA）. The content of glycogen was high in January and March （2.89 and 2.82 g（100 g） ^-1 on average, respectively） and low in October （2.07g（100g）^- 1 on average）. The low content of neutral lipids in October reflected a relatively poor nutritional value of oyster （1.42 g（ 100 g）^- 1 on average）. The main fatty acids of oyster were palmitic acid （16：0）, oleic acid （18： 1）, eicosapentaenoic acid （EPA, 20： 5（0 3） and docosahexaenoic acid （DHA, 22：6（0 3）. The major FAAs of oyster were Taurine, Glutamicacid, Glycin, Alanine, Arginine and Proline. Taurine was the most abundant FAA with its content ranging from 603 mg（100 g） ^-1 to 1 139 mg（ 100 g） ^-1. The high contents of glycogen, polyunsaturated fatty acid and FAA showed that oyster cultured along the eastern coast of Shandong Province was nutritionally good in January and March.
