This paper presents the design and analysis of a distributed power amplifier with 6-d B bandwidth from 10 MHz to 6 GHz. To meet the stringent targeted specification, the concurrent design and analysis are carefully performed with optimizations in both passive and active devices. The gate capacitive division technique is proposed and proven theoretically of bandwidth extension effect and power efficiency enhancement. To validate the theory, a prototype is designed in a 0.25-μm Ga As technology. The fabricated amplifier chip is packaged in an evaluation cavity of SMA connectors. The measurement shows an average power gain of 15 d B, OP1 d Band PSAT of 31 d Bm and 32.6 d Bm at 3 GHz, and PAE at OP1 d Band PSAT points are 31.5% and 43.7% respectively. To the best of authors’ knowledge, the amplifier achieves the highest Power-added efficiency(PAE) among the similar Ga As amplifiers.

In this paper, a wavelet-fi ltered genetic-neuro-fuzzy(WGNF) control system design framework for response control of a highway bridge under various earthquake loads is discussed. The WGNF controller is developed by combining fuzzy logic, discrete wavelet transform, genetic algorithms, and neural networks for use as a control algorithm. To evaluate the performance of the WGNF algorithm, it is tested on a highway bridge equipped with hydraulic actuators. It controls the actuators installed on the abutments of the highway bridge structure. Various earthquakes used as input signals include an artifi cial earthquake, the El-Centro, Kobe, North Palm Springs, Turkey Bolu, Chi-Chi, and Northridge earthquakes. It is proved that the WGNF control system is effective in mitigating the vibration of the highway bridge under a variety of seismic excitation.

AIM To analyze cytokine levels and to identify their association with outcome in patients with hepatocellular carcinoma(HCC) treated with radiotherapy(RT). METHODS Patients with HCC who were treated with RT were eligible for this prospective study. Blood samples were collected before and after RT, and serum cytokine levels including interleukin(IL)-1, IL-6, IL-8, IL-10, IL-12, and tumor necrosis factor-α were analyzed. RESULTS Between 2008 and 2009, 51 patients were enrolled in this study. Baseline IL-6 level was high in patients with a history of pre-RT treatment. Median survival was 13.9 mo with alpha-fetoprotein(AFP) as a significant factor(P = 0.020). Median failure-free survival(FFS) for infield, outfield-intrahepatic and extrahepatic failures were 23.3, 11.5 and 12.0 mo, respectively. Sex and baseline IL-6 level were associated with infield FFS, and baseline IL-10 level was correlated with outfield-intrahepatic FFS. For extrahepatic FFS, AFP was significant(P =0.034). Patients with a baseline IL-6 level of ≥ 9.7 pg/m L showed worse infield FFS(P = 0.005), and this significance was observed only in treatment-non-na?ve patients(P = 0.022). CONCLUSION In addition to AFP, cytokines seem useful in predicting infield and outfield-intrahepatic failure. Serum cytokines could be useful biomarkers for predicting RT outcome in HCC.

In this paper evidences of strong interaction between several tris-bipyridyl complexes and Nafion matrix are provided by UV-VIS and FTIR spectra. The studied counterions also show electrostatic interaction with the bonded -SO3 groups as indicated by the shifting of gamma(s)so(3) to lower wave number. The most probable location of these complexes seems to be near the interface between the fluorocarbon back bone and the ionic duster region.

Three archived reanalysis wind vectors at 10 m height in the wind speed range of 2-15 m/s,namely,the second version of the National Centres for Environmental Prediction(NCEP)Climate Forecast System Reanalysis(CFSv2),European Centre for Medium-Range Weather Forecasting Interim Reanalysis(ERA-I)and NCEPDepartment of Energy(DOE)Reanalysis 2(NCEP-2)products,are evaluated by a comparison with the winds measured by moored buoys in coastal regions of the South China Sea(SCS).The buoy data are first quality controlled by extensive techniques that help eliminate degraded *** evaluation results reveal that the CFSv2 wind vectors are most consistent with the buoy winds(with average biases of 0.01 m/s and 1.76°).The ERA-I winds significantly underestimate the buoy wind speed(with an average bias of-1.57 m/s),while the statistical errors in the NCEP-2 wind direction have the largest *** diagnosis of the reanalysis wind errors shows the residuals of all three reanalysis wind speeds(reanalysis-buoy)decrease with increasing buoy wind speed,suggesting a narrower wind speed range than that of the ***,wind direction errors are examined to depend on the magnitude of the wind speed and the wind speed *** general,the evaluation of three reanalysis wind products demonstrates that CFSv2 wind vectors are the closest to the winds along the north coast of the SCS and are sufficiently accurate to be used in numerical models.

水下地形辅助导航的关键在于地形匹配,匹配定位的一个重要问题就是匹配结果是否可靠。从影响匹配结果的另外一个重要因素地形导航信息量出发,选取了地形高度标准差、信噪比、地形熵、相似度4个特征向量来判定匹配结果的置信度。仿真结果表明,当水下航行器进入地形信息丰富(置信度高)的区域后,地形辅助导航系统可靠性比较高,位置误差从3〞降低到1.5〞以内,为水下航行器导航提供了可靠的位置信息源。
