In parallel hybrid electrical vehicle （PHEV） equipped with automatic mechanical transmission （AMT）, the driving smoothness and the clutch abrasion are the primary considerations for powertrain control during gearshift and clutch operation. To improve these performance indexes of PHEV, a coordinated control system is proposed through the analyzing of HEV powertrain dynamic characteristics. Using the method of minimum principle, the input torque of transmission is optimized to improve the driving smoothness of vehicle. Using the methods of fuzzy logic and fuzzy-PID, the engaging speed of clutch and the throttle opening of engine are manipulated to ensure the smoothness of clutch engagement and reduce the abrasion of clutch friction plates. The motor provides the difference between the required input torque of transmission and the torque transmitted through clutch plates. Results of simulation and experiments show that the proposed control strategy performs better than the contrastive control system, the smoothness of driving and the abrasion of clutch can be improved simultaneously.

A new method concerning with the simultaneous reinforcing and toughening of polypropylene （PP） was reported. Dynamical cure of the epoxy resin was successfully applied in the PP/maleic anhydride-grafted styrene-ethylene-butylene-styrene （SEBS） triblock copolymer, and the obtained blends named as dynamically cured PP/MAH-g-SEBS/epoxy blends. The stiffness and toughness of the blends are in a good balance, and MAH-g-SEBS was acted as not only an impact modifier but also a compatibilizer. The structure of the dynamically cured PP/MAH-g-SEBS/epoxy blends is the embedding of the epoxy particles by the MAH-g- SEBS.C2009 Xue Liang Jiang.

A supersaturated design （SSD）, whose run size is not enough for estimating all the main effects, is commonly used in screening experiments. It offers a potential useful tool to investigate a large number of factors with only a few experimental runs. The associated analysis methods have been proposed by many authors to identify active effects in situations where only one response is considered. However, there are often situations where two or more responses are observed simultaneously in one screening experiment, and the analysis of SSDs with multiple responses is thus needed. In this paper, we propose a two-stage variable selection strategy, called the multivariate partial least squares-stepwise regression （MPLS-SR） method, which uses the multivariate partial least squares regression in conjunction with the stepwise regression procedure to select true active effects in SSDs with multiple responses. Simulation studies show that the MPLS-SR method performs pretty good and is easy to understand and implement.

In the detection of multi-component gas based on tunable diode laser absorption spectroscopy(TDLAS),the problem of overlapping interference between the absorption lines of each gas is often *** example,when detecting a gas mixture of sulphur dioxide(SO_(2))and thionyl fluoride(SOF_(2)),the characteristic decomposition components of SF6,there is overlapping interference in the absorption lines of the two gases,which makes it difficult to detect the concentration of gases *** view of this problem,a novel method based on support vector regression model used for TDLAS is proposed to detect two gases *** detection results show that the correlation coefficients between the concentration of SO_(2)and SOF_(2)and the average value of the second harmonic peak reached 0.992 and *** addition,through model testing,different concentrations of SO_(2)and SOF_(2)gas mixture are simultaneously detected,and the resulting maximum errors for measuring SO_(2)and SOF_(2)concentrations are less than 7.13×10^(-5)and 0.26×10^(-2).The maximum errors of the measurement results in the verification test are not more than 6.4×10^(-3)and 4.6×10^(-2).Therefore,with assistance of the novel method,the detection of multiple gases by using a single laser is achieved.

OBJECTIVE： To evaluate the efficacy and safety of acupuncture therapy for children with cerebral palsy. DATA SOURCES： We conducted electronic searches of PUBMED（1950/2017）, EMBASE（1974/2017）, Science Direct（1986/2017）, Academic Source Premier（1887/2017）, the Cochrane Library（Issue 4, April 2017）, Science Citation Index Expanded（1900/2017）, China National Knowledge Infrastructure（1915/2017）, China Biological Medicine（1990/2017-04）, Wan Fang（1980/2017）, VIP（1989/2017）, and Chinese Science Citation Database（1989/2017）. DATA SELECTION： We included randomized controlled trials that aimed to compare the effect of acupuncture plus rehabilitation training versus rehabilitation training alone. Data about functional motor abilities, daily activity/social participation, effective rate, intellectual development, and adverse effects were included. We used Revman 5.2 software for statistical analysis. OUTCOME MEASURES： The primary outcomes included functional motor abilities, daily activity, and effective rate. The secondary outcomes included intellectual development and adverse ***： Twenty-one studies with a total of 1718 participants met the inclusion criteria. The effect size of gross motor function（SMD = 0.64, 95% CI： 0.52 to 0.76, P 〈 0.00001; I^2 = 0%, P = 0.69; in 13 studies with 1144 patients） and the total effective rate（RR = 1.28, 95% CI： 1.20 to 1.37, P 〈 0.00001; I^2 = 18%, P = 0.27; in 12 studies with 1106 patients） suggested that acupuncture plus rehabilitation produced a significant improvement in gross motor function and a high total effective rate. The pooled fine motor function（SMD = 3.48, 95% CI： 2.62 to 4.34, P 〈 0.00001; I^2 = 64%, P = 0.10; in 2 studies with 193 patients）, modified Ashworth scale scores（SMD = –0.31, 95% CI： –0.52 to –0.11, P = 0.003; I^2 = 74%, P = 0.004; in 5 studies with 363 patients） and activities of daily living（SMD = 1.45, 95% CI： 1.20 to 1.71, P 〈 0.00001; I^2 = 78%, P = 0.004; in 4 studies with 313 patients） also indicate
