With the gradual increase in the number of the same components in the structure, the hybrid test efficiency of taking only one of the components to test the actual test will gradually decrease. For this reason, this paper proposes a structure hybrid test method based on offline model parameter modification to improve the test efficiency. Starting from the goal of obtaining the hierarchical seismic response of the structural system, the method first extracts the key parts from the overall structure as the test substructure to perform a pseudo-static test of the preset loading path, and then identifies the restoring force based on the measured force-displacement curve of the test substructure Model parameters. Finally, the identified model parameters are used in the numerical simulation of the seismic response of the overall structure. A virtual hybrid test of a steel frame structure with anti-buckling support as the test substructure was carried out using MATLAB and OpenSees. The results show that for the case where the performance of the test substructure is less affected by the loading path, the hybrid test method has higher test accuracy and Test efficiency.

Objective To investigate the effect of Shenfuhuang Formula on spatial learning and memory, anxiety state，and hippocampal CA1 synaptic plasticity in sepsis mice. Methods C57BL/6 mice were randomly divided into control group， model group and Shenfuhuang group. The sepsis model established with cecal ligation and perforation （ CLP） in the latter two groups. The Shenfuhuang group was gavaged with 2. 5 g/kg Shenfuhuang Decoction? twice daily，with a total volume of 0. 5 mL； the model group and the control group were given 0. 5 mL normal saline twice daily. Morris water maze test was used to evaluate the spatial learning and memory ability. The open field test was used to evaluate the exploration ability and anxiety state. The long-term potentiation of hippocampal CA1 area was also recorded in vivo by neurophysiological technology. Results Compared with the control group，in model group the escape latency and the time spent in target quadrant of Morris water maze were significantly reduced （P < 0. 05 ） ； the number of crossing? rearing and center duration of the open field test were significantly reduced （P < 0, 05） ； and the slope of the field post-synaptic potential were significantly reduced （jP <0. 05）. Compared with the model group，in Shenfuhuang group the escape latency and the time spent in target quadrant were significantly increased (P < 0. 05) ； the number of crossing, rearing and center duration of the open field test were significantly increased (P <0. 05) ； and the slope of the field post-synaptic potential were significantly increased (P < 0. 05). Conclusion Shenfuhuang Formula seems to improve the cognitive impairment and behavioral ability of CLP mice to a certain degree，and its mechanism may be related to the improvement of synaptic plasticity in the hippocampus.

An ortho-diamine monomer, 4-phenoxy-1,2-phenylenediamine (POPDA), was synthesized via two-step reactions. It was randomly copolymerized with 4,4 ’-dicarboxydiphenyl ether (DCDPE), 5-aminoisophthalic acid (APA) and 3,3 ’- diaminobenzidine (DAB) in polyphosphoric acid to yield a new kind of high molecular weight poly(ether ketone benzimidazole) copolymers (PEKBI-x, ‘x’ refers to the molar fraction of POPDA in aromatic diamines (POPDA and DAB). The resultant PEKBI-x was sulfonated using fuming sulfuric acid as the sulfonating reagent to give the corresponding sulfonated poly(ether ketone benzimidazole)s (SPEKBI-x). No significant polymer degradation was observed during the process of sulfonation reaction indicating excellent chemical stability of the copolymers PEKBI-x. A series of covalently crosslinked membranes (SPEKBI-x-CL) were prepared via the solution cast method, and the cross-linking reaction occurred between the amino groups of the APA moiety of the SPEKBI-x and the epoxy groups of the cross-linker 1,2,7,8- diepoxyoctane during the process of solvent evaporation. The thermal stability, mechanical properties, water uptake, swelling ratio, proton conductivity, ion exchange capacity, radical stability, and single cell performance of the exchange proton membranes were investigated. Results showed that these cross-linked membranes exhibited very high ion exchange capacities (2.88～3.28 meq/g) and good mechanical and thermal properties. With the increase of POPDA content in the copolymers, the proton conductivity of the proton exchange membrane increased. A preliminary test of H2-O2 single cell revealed that the maximum output power density of the single cell assembled with the SPEKBI-0.50-CL membrane reached 662 mW/cm2 at 80 ℃, 80% relative humidity and 100 kPa back pressure, which was slightly higher than that of the one assembled with Nafion212 (631 mW/cm2) under the same test conditions.

Unbalanced consumption of fat-rich foods tends to increase high risk of chronic diseases and death. A promising way is to create reduced-fat and fat-free products to solve the problems. However, the reduction of fat content normally can cause some changes, such as undesired texture, in food production. This study aims to investigate the aggregation behavior of alginate (Alg) sodium and egg yolk proteins under acidic pH conditions, and further to design a sort of low-fat mayonnaise products based on the aggregation mechanism. All low-fat mayonnaise products showed 30% oil phase fraction, and some significant properties of high viscoelasticity and thixotropy. A high fat mayonnaise with 75% oil phase fraction was used as a control. The results show that when the pH value was lower than 5.0, Alg carried negative charges but the dispersion of egg yolk carried positive charges, indicating that an obvious electrostatic aggregation occurred between Alg and egg yolk proteins. The structural strength of the mixture system of Alg and egg yolk significantly increased in this case. The Confocal laser scanning microscope (CLSM) results showed that Alg and egg yolk has formed aggregates at the pH value lower than 5.0. However, there was no any aggregates to be observed when the pH value was higher than 5.0. It was also found that addition amounts of white vinegar (0-10 mL, at a fixed total volume of 100 mL mayonnaise product) can determine the structuralized process in the low-fat mayonnaise products. The reason can be explained by the fact that the vinegar addition can decrease the pH value in the mayonnaise system, and thereby lead to the electrostatic attraction between Alg and egg yolk proteins. When the amount of white vinegar was higher than 2% (v/v), the pH value of the mayonnaise decreased to below 5.0, indicating that white vinegar can induce the electrostatic aggregation effect of the mayonnaise, thereby to increase the structural strength of products. With the increase in the addition amount of white vinegar, the aggregation effect was much more significant, and the structural degree was much higher than before in the low-fat mayonnaise products. In addition, the structural mechanism of the mayonnaise products can be that, the egg yolk-stabilized emulsion was dispersed into the mayonnaise systems, where the aggregates of egg yolk proteins and Alg acted as the continuous phase to confer the mayonnaise with significant viscoelasticity and thixotropy. Further investigations showed that the thermal stability of the low-fat mayonnaise products was affected by the addition amount of white vinegar. Good freeze-thaw stability can be achieved in all mayonnaise products, whereas the excessive addition of white vinegar can reduce the thermal stability of the low-fat mayonnaise products. The over addition of white vinegar can also decrease the flavor and sensory acceptability of the mayonnaise products. The rheological properties of the prepared low-fat mayonnaise product were close to those of the control group, and the sensory acceptability reached the highest, when the addition amount of white vinegar was 4% (pH value 4.6). Compared with the high fat mayonnaise (control), the low-fat mayonnaise demonstrated the similar texture but contained less fat. This finding can provide a novel and facile approach to develop the promising reduced-fat food products. [ABSTRACT FROM AUTHOR]
