In this paper, the fuzzy ISODATA algorithm is applied to forecasting liquefaction of sand in the antiseismic structures. According to the data of the earthquake taken place in Tang Shan in 1976, we construct a model of mathematics, on which we forecast 32 samples in the earthquake of Tang Shan. The correct rate of forecast is 90.7 %.

A novel recombinant Bacille Calmette-Guerin (rBCG) vaccine co-expressed Eimeria tenella rhomboid and cytokine chicken IL-2 (chIL-2) was constructed, and its efficacy against E. tenella challenge was observed. The rhomboid gene of E. tenella and chIL-2 gene were subcloned into integrative expression vector pMV361, producing vaccines rBCG pMV361-rho and pMV361-rho-IL2. Animal experiment via intranasal and subcutaneous route in chickens was carried out to evaluate the immune efficacy of the vaccines. The results indicated that these rBCG vaccines could obviously alleviate cacal lesions and oocyst output. Intranasal immunization with pMV361-rho and pMV361-rho-IL2 elicited better protective immunity against E. tenella than subcutaneous immunization. Splenocytes from chickens immunized with either rBCG pMV361-rho and pMV361-rho-IL2 had increased $CD4^+$ and $CD8^+$ cell production. Our data indicate recombinant BCG is able to impart partial protection against E. tenella challenge and co-expression of cytokine with antigen was an effective strategy to improve vaccine immunity.

With the development of autonomous driving technology, the number of external contact sensors mounted on vehicles is increasing, and the importance is also rising. The vehicular ultrasonic sensor uses the LIN protocol in the form of a bus topology and reports a status message about its surroundings through the vehicle's internal network. Since ultrasonic sensors are vulnerable to various threats due to poor security protocols, physical testing on actual vehicle is needed. Therefore, this paper developed a LIN-CAN co-analysis testbed with a jig for location-specific distance test to examine the operational relation between LIN and CAN caused by ultrasonic sensors.

In oriental medicine, there is the fundamentals to lead a stirring life, and it is an important matter that make a study of fundamentals for treatment. The su-wen(素問) mentions the fundamentals of sheng(生之本), the fundamentals of qi(氣之本), the fundamentals of feng-cang(封藏之本), the fundamentals of ba-ji(罷極之本) and the fundamentals of cang-lin(倉廩之本). They are terminologies expressing physiological functions of the five viscera - heart, lungs, kidneys, liver and spleen. The five viscera are expressed through face, fur, hair, nail and lips. And the five viscera are closely connected with blood, skin, bone, muscle and flesh. Through the changes of personal appearance, we can recognize those of their internal organs. In oriental medicine, they are called as the cang-xiang(藏象). Heart is the fundamentals of sheng(生), and it is related to spirit, blood and blood vessel. Lungs are the fundamentals of qi(氣), because they master the extensive meaning of qi(氣). Kidneys are the fundamentals of feng-cang(封藏) which means seclusion. Liver is the fundamentals of ba-ji(罷極) that have several view by concept. Spleen, stomach, large and small intestines, paunch and bladder are the fundamentals of cang-lin(倉廩), that is to say, gastrointestinal tract that ingest diet and digest it.

The objective of the present study was to identify differences in the expression levels of liver proteins between healthy and ketotic cows, establish a liver metabolic interrelationship of ketosis and elucidate the metabolic characteristics of the liver during ketosis. Liver samples from 8 healthy multiparous Hostein cows and 8 ketotic cows were pooled by health status and the proteins were separated by two-dimensional-electrophoresis (2D-E). Statistical analysis of gels was performed using PDQuest software 8.0. The differences in the expression levels of liver proteins (p<0.05) between ketotic and healthy cows were identified by matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF-TOF) tandem mass spectrometry. Five enzymes/proteins were identified as being differentially expressed in the livers of ketotic cows: expression of 3-hydroxyacyl-CoA dehydrogenase type-2 (HCDH), acetyl-coenzyme A acetyltransferase 2 (ACAT) and elongation factor Tu (EF-Tu) were down-regulated, whereas that of alpha-enolase and creatine kinase were up-regulated. On the basis of this evidence, it could be presumed that the decreased expression of HCDH, which is caused by high concentrations of acetyl-CoA in hepatic cells, in the livers of ketotic cows, implies reduced fatty acid ??oxidation. The resultant high concentrations of acetyl-CoA and acetoacetyl CoA would depress the level of ACAT and generate more ??hydroxybutyric acid; high concentrations of acetyl-CoA would also accelerate the Krebs Cycle and produce more ATP, which is stored as phosphocreatine, as a consequence of increased expression of creatine kinase. The low expression level of elongation factor Tu in the livers of ketotic cows indicates decreased levels of protein synthesis due to the limited availability of amino acids, because the most glucogenic amino acids sustain the glyconeogenesis pathway; thus increasing the level of alpha-enolase. Decreased protein synthesis also promotes the conversion of amino acids to oxaloacetate, which drives the Krebs Cycle under conditions of high levels of acetyl-CoA. It is concluded that the livers of ketotic cows possess high concentrations of acetyl-CoA, which through negative feedback inhibited fatty acid oxidation; show decreased fatty acid oxidation, ketogenesis and protein synthesis; and increased gluconeogenesis and energy production.

This paper studies the characteristics of the restructuring of chemical industrial complex in JiLin city since 1978 focusing on enterprise organization, the process of production, labor, and consumer market. The number of chemical industrial enterprises and their partnership with subcontractors have increased since 2001. As for the type of cooperation group, research institutes and local government are accounted for the greatest portion. The chemical industrial enterprise in JiLin which has adopted Fordism production method still has the highest percentage in 2007. And in the shift process of production system after China's entry into WTO(in 2001), chemical industrial enterprise in JiLin city takes allowing more investment in production technologies as core strategy, while taking improvement in equipment and development of new products as core strategy in the shift process of production technology. The degree of labor re-education was highest in 2007, and as for the relationship between labor and management, enterprises which evaluate the ability of performance of duty are increasing. The characteristics of restructuring of chemical industrial complex on consumer market, domestic market accounted for the greatest portion, on the other side the export is feeble. As for strategy of market restructuring, industrial enterprise in JiLin city should use Quality improvement and high-value added as core strategies to cope with alteration of market.

The complex battlefield environment makes it difficult to intercept maneuvering targets for guided missiles. In this paper, a finite-time convergent (FTC) guidance law based on the second-order sliding mode (SOSM) control theory is proposed to achieve the requirements of stability, accuracy and robustness. More specifically, a second-order sliding mode observer (SMOB) is used to estimate and compensate for the total disturbance of the controlled system, while the target acceleration is extracted from the line-of-sight (LOS) angle measurement. The proposed guidance law can drive the LOS angular rate converge to zero in a finite time, which means that the missile will accurately intercept the target. Numerical simulations with some comparisons are performed to demonstrate the superiority of the proposed guidance law.
