Improving the transient stability of the converter bus voltage plays an important role in ensuring the safe operation of DC (direct current) power transmission. On the basis of the study of the impact of the steady-state output reactive power coordination between synchronous condenser and AC(alternating current) filter on the transient stability of the converter bus voltage, the regression modeling method for predicting bus voltage transient stability margin based on bus voltage and steady-state reactive power coordination state of the converter station was proposed by using voltage transient stability margin index based on multi-binary table description and support vector machine. Further, using the regression model, a coordinated optimization method of the steady-state reactive power of synchronous condenser and AC filter to improve the transient stability margin of the converter bus voltage and reduce the system network loss was proposed. Finally, the effectiveness of the proposed machine learning-based reactive power coordination optimization method to enhance the bus voltage transient stability of Nanchang converter station was verified using the PSASP( power system analysis software package) computational analysis model of Yazhong DC feeding into Jiangxi grid. Simulation results show that the optimization method can fully excavate the ability of the synchronous condenser to improve the transient stability of the converter bus voltage against severe fault disturbances based on dynamic reactive power support, while reducing the number of AC filters put into operation.

Wearable devices have attracted tremendous interest in recent decades, but the rigidity of traditional battery components limits its development. To power up the wearable devices, it is urgent to develop a new type of stretchable energy storage devices. A series of representative stretchable battery preparation methods have been reported. This review summarizes the related works in this field, divides the strategies to achieve stretchability into two categories: device-level and component-level. We focus on the structural design in different dimensions and the preparation methods of each stretchable component to achieve stretchability, analysing the advantages and shortcomings of both ways. The general issues such as energy density, interface degradation, encapsulation process and device integration of the stretchable battery are pointed out, and the future development trend is also foreseen.

Objective　To evaluate the effects of different solubilizing techniques on the in vitro dissolution and in vivo pharmacokinetics of Sirolimus (SRL). Methods　Solid dispersions (SD), inclusion complex (IC), self-micro emulsifying drug delivery system (SMEDDS) and nano-structured lipid carrier (NLC) were selected as the solubilization technology for SRL. SRLSMEDDS and SRL-NLC have obtained the optimal prescription in the previous studies. Additionally, the formulation process of SRL-SD and SRL-IC was screened by using inclusion rate and dissolution profiles as indicators. 0.4% SDS, water and buffer solutions with pH 1.2, 4.5, 6.8, 7.4 were used as dissolution media. The dissolution profile of the commercially available formulation Rapamune® and the lab-made solubilized preparations were investigated. The in vivo absorption of the above preparations was examined using a pharmacokinetic test in Beagle dogs. Results　In 0.4% SDS, the dissolution of each preparation exceeded 80% in 2 h. In the medium of pH 1.2, the dissolution of SRL-SD could not be measured while the dissolution of IC, SMEDDS and NLC increased first and then decreased. In other media, the dissolution of the SRL was reduced. The SRL-IC showed the best dissolution without a significant decrease. The relative bioavailability of APIs, SRL-SD, SRL-IC, SRL-NLC and SRLSMEDDS were 9.1%, 18.7%, 33.2%, 78.0%, and 97.6% respectively in vivo pharmacokinetic tests. Conclusion　SD, SMEDDS, NLC, and IC can improve the in vitro dissolution and in vivo absorption of SRL. Among them, SMEDDS has the most significant improvement in the bioavailability of SRL.

One of the problems in the analysis of the dynamics performance of off-road vehicles is the effect of the accuracy of the hydro-pneumatic suspension model. However, the accuracy of the model for the polytropic process of nitrogen in the gas-charged hydraulic accumulator is one of the key factors, which affects the accuracy of the model for the hydro-pneumatic suspension systems. The traditional approach based on the energy equation and the Benedict-Webb-Rubin equations deduces the well-known thermal time constant model. However, researchers indicate that the thermal time constant varies with the change in the accumulator size and operating cases. Other researchers attempt to modify the polytropic exponent to model the real gas behavior, but the hysteresis loop representing the energy losses in a cycle can’t be described because the polytropic exponent is treated as a constant value. In this paper, an attempt was made to describe the hysteresis loop by adopting a variable polytropic exponent. On the accumulator rig, some tests excited by the sinusoidal displacement with four different amplitudes and frequencies respectively were carried out. The plots of the gas pressures versus the gas volume ratio and the gas volume rate respectively were made according to the experimental data from the accumulator test by using the Matlab software. A comprehensive analysis of experimental data showed that the relationship between the gas pressure and both the volume compression ratio and the volume compression rate were very close. To analyze the relationship between the polytropic exponent and the two parameters respectively, the formula of the polytropic exponent was deduced based on the ideal gas approach and polytropic processes. By substituting the experimental data from the accumulator test into the formula, the plots of the polytropic exponent versus the two parameters respectively were also made. The plots illustrated that the polytropic exponent was closely proportional to the two parameters, respectively. Based on the analysis, a novel method was proposed to build a polytropic exponent model with the two parameters to describe the real gas behavior. In order to verify the correctness and the accuracy of the proposed polytropic exponent model, the two coefficients in the model were identified by using the experimental data from the previous accumulators test, and the coefficient of the volume compression ratio in the model (k1) was 2.4 for the test accumulator, and the coefficient of the volume compression rate (k2) was 1.5. Moreover, substituting the values of the two parameters, which were determined by the different operating cases, into the proposed polytropic exponent model with the two identified coefficients gave a comparison with these experimental data. Furthermore, a co-simulation model, which was based on the polytropic exponential model, for six hydro-pneumatic suspension systems was built to check the application of the polytropic exponent model in the hydro-pneumatic suspension systems of the overall vehicle. And a platform for the hydro-pneumatic suspension systems of the overall vehicle invented and designed by our laboratory, which was the first platform with the capability to test the comprehensive characteristics of multiple suspension systems, was used to test the rolling characteristics of the six hydro-pneumatic suspension systems. Several tests were carried out under the sinusoidal displacements with four different amplitudes and frequencies, respectively. The comparison of the co-simulation results and experimental data showed that the average discrepancy was equal to 5.12% and the maximum discrepancy was less than 10.9%. Therefore, a good correlation was achieved. It further demonstrated that the proposed polytropic exponent model can describe the behavior of the real nitrogen in the accumulator. But the proposed model should be further verified by using more experimental data from much higher frequency tests, and the influence of dissipated energy on the two coefficients in the proposed model should be explored.

As Biomaterials has been widely used in clinical, BCI(Biomaterial centered infection) has already become a serious problem in Nosocomial Infection. It was reported that, the BCI accounts for 50% Nosocomial Infection. Escherichia coli(E.coli) is one of the most common microorganisms associated with BCI. The formation of Bacterial biofilm(BF) on the surface of Biomaterials is the main reason that BCI can’t be controlled. In the BF state, microorganisms are relatively immune to antibodies and resistant to conventional antimicrobial agents. The motility of E.coli is closely related to BF formation, and flagella is the sport organs of E.coli. The generation of flagella need 3 levels gene expression, and operon flh DC is the first level and master control gene. We speculate that: There are one-to-one relationship with The expression of operon flh DC→The generation of flagella→The motility of E.coli →Bacteria biofilm formation, which provides new ideas for clinical prevention and treatment of IAI. In this paper, in order to make a brief review on the relationship of E.coli’s flagella regulator genes flh DC and Implant-Associated Infection caused by E.coli.. [ABSTRACT FROM AUTHOR]

Objective To investigate the relationship between XRCC1 Arg399 Gln polymorphisms and the efficacy of platinum-based chemotherapy in non-small cell lung cancer （NSCLC） . Methods Eighty-three patients with NSCLC treated with platinum-based chemotherapy were enrolled in this study and their tumor samples were collected retrospectively for analysis. The polymorphisms of XRCC1 Arg399 Gln in NSCLC were detected by polymerase chain reaction-restriction fragment length polymorphism （PCR-RFLP), and the data were collected and analyzed. Results Of all cases, the frequencies of XRCC1 codon 399 Arg /Arg, Arg /Gln and Gln /Gln genotype were 59.04%，33.73% and 7.23%，respectively. The response rate to therapy in patients with XRCC1 codon 399 Arg /Arg genotype （42.86%） was significantly higher than that in patients with the Arg /Gln and Gln/Gln genotype （11.76%). The response rate to therapy in patients with XRCC1 codon 399 Arg/Arg genotypes was significantly higher than that in patients with other XRCC1 genotypes. XRCC1 genotypes had no significant correlation with the side effects of chemotherapy. Conclusion It has certain relationships between the polymorphisms of XRCC1 Arg399 Gln and platinum-based chemotherapy in NSCLC， and the patients with XRCC1 399Arg/Arg are more conducive to use platinum-based chemotherapy. The results can provide some basis for clinical medication. [ABSTRACT FROM AUTHOR]

In order to reveal the deep coal reservoir adsorption characteristics of coal and the quantitative characterization on the amount of adsorbed gas of coalbed methane, this paper studied the coal samples of carboniferous-permian in eastern Ordos Basin and analyzed the methane isothermal adsorption experiments of high temperatures and pressures of coal samples. An interpretation of the adsorption characteristics was made under high temperatures and pressures from the geological factors including coal rank, temperature and pressure. The curves of coal adsorption characteristic and the prediction model of amount of adsorbed gas with different coal ranks were established based on the adsorption potential theory. Meanwhile, a case study on the amount of adsorbed gas of the No. 8+9 coal seam in Linxing area was analyzed based on this model. The results show that the adsorption characteristics of deep coal reservoir are comprehensively influenced by temperature,pressure and coal rank. When the coal rank is between 0.77% and 2.18%, which is from gas coal to poor coal, the coal rank and pressure show a positive effect on adsorption ability, but temperature has a negative effect. In addition, the negative effect is more significant with the pressure increases. Different coal ranks have different curves of coal adsorption characteristic. The higher of coal rank, the slower of rate at which the adsorption potential decreases as the adsorption space increases. The calculation of the amount of absolute adsorbed is between 19.6 cm3/g and 31.1 cm3/g, and the gas saturation is between 37.8% and 78.8% in the study area [ABSTRACT FROM AUTHOR]
