The scope of this paper is to forecast wind speed. Wind speed, temperature, wind direction, relative humidity, precipitation of water content and air pressure are the main factors make the wind speed forecasting as a complex problem and neural network performance is mainly influenced by proper hidden layer neuron units. This paper proposes new criteria for appropriate hidden layer neuron unit’s determination and attempts a novel hybrid method in order to achieve enhanced wind speed forecasting. This paper proposes the following two main innovative contributions 1) both either over fitting or under fitting issues are avoided by means of the proposed new criteria based hidden layer neuron unit’s estimation. 2) ELmAN neural network is optimized through modified Grey Wolf Optimizer (mGWO). The proposed hybrid method (ELmAN-mGWO) performance, effectiveness is confirmed by means of the comparison between Grey Wolf Optimizer (GWO), Adaptive Gbest-guided Gravitational Search Algorithm (GGSA), Artificial Bee Colony (ABC), Ant Colony Optimization (ACO), Cuckoo Search (CS), Particle Swarm Optimization (PSO), Evolution Strategy (ES), Genetic Algorithm (GA) algorithms, meanwhile proposed new criteria effectiveness and precise are verified comparison with other existing selection criteria. Three real-time wind data sets are utilized in order to analysis the performance of the proposed approach. Simulation results demonstrate that the proposed hybrid method (ELmAN-mGWO) achieve the mean square error AVG ± STD of 4.1379e-11 ± 1.0567e-15, 6.3073e-11 ± 3.5708e-15 and 7.5840e-11 ± 1.1613e-14 respectively for evaluation on three real-time data sets. Hence, the proposed hybrid method is superior, precise, enhance wind speed forecasting than that of other existing methods and robust.

道理很简单：买优衣库衣服的人，会选择比优衣库高一个档次（品牌和价格）的鞋。鞋子的重复使用率远远高于衣服，我衣柜里衣服和鞋子数量的比例怎么也有10：1吧。如果是男士，鞋子数量会更少。此外，鞋子的档次和舒适度关系比衣服更加密切。而且一旦穿了更昂贵更好鞋子，基本就不会退回原先使用的那个层次，宁可少买一点。脚感这个东西太强大了。

采用急冷Ni-8Co-4Cr-0.5W-3.2B中间层合金箔,对DD6镍基单晶高温合金进行了瞬时过渡液相扩散连接,连接温度为1200℃。理论分析了TLP焊等温凝固时间、固相成分均匀化时间及降熔元素硼向母材的扩散深度,其值分别为6.4 h、9.6 h和170μm。试验结果表明,在1200℃×12 h进行TLP焊连接,可以获得无共晶相产生的组织均匀的等温凝固焊缝;通过对接头进行后续的标准化热处理,焊缝中γ′相完全立方化,界面两侧γ′相晶粒尺寸相同,分布均匀,排列齐整,镶嵌于连续均匀的母材之中,γ′相的结晶取向与母材相一致,实现了DD6单晶扩散连接界面组织的单晶化。理论预测结果与试验结果相吻合。

我们先前研究表明胶质细胞源性神经营养因子(GDNF)联合施万细胞移植能促进脊髓损伤后轴突再生和髓鞘形成。然而,GDNF介导这一过程的细胞靶点尚不清楚。在此,我们报道了GDNF可增加在体再生轴突的数目和直径,并促进体外背根神经节神经元的轴突向外生长,提示GDNF对神经元有直接作用。在施万细胞-背根神经节神经元共培养下,GDNF显著增加施万细胞生成的髓鞘数目;GDNF处理对孤立培养的施万细胞增殖无作用,但可促进已与神经轴突有突触联系的施万细胞增殖;GDNF可增加孤立施万细胞中分子量为140kDa的神经细胞黏附分子(NCAm)的表达,但对黏附分子L1表达或神经营养因子NGF、NT3及BDNF分泌没有影响。总之,这些结果支持假设:GDNF提高轴突再生和施万细胞髓鞘形成主要是通过GDNF对神经元的直接作用介导的,并且提示GDNF联合施万细胞移植可能是促进脊髓损伤后轴突再生和髓鞘形成的有效策略之一。

本文通过对庄浪徐家碾剖面全新世黄土-古土壤序列中磁化率与各粒级的相关性分析,认为粘粒组分(m),细粉砂组分(10-5μm)与磁化率呈正相关关系,粗粉砂组分(50-10μm),砂粒组分(>50μm)与磁化率呈反相关关系.其次,对粒度分离后磁化率贡献的测量计算,结果指出粗粉砂(50-10μm)在全剖面对磁化率的贡献最大,其在古土壤层中对磁化率的贡献低于黄土层;其次是粘粒组分(m),在古土壤层中对磁化率的贡献高于黄土层.粗粉砂对磁化率的贡献主要受到粒级含量的影响,而粘粒物质对磁化率的贡献主要源于其较高的粒级磁化率;粒度分离后各粒级的磁化率呈现出颗粒越细,磁化率越高的变化趋势.这可能是由于细颗粒物质中富含铁磁性矿物,而粗颗粒物质中含有碳酸钙等逆磁性矿物使其粒级磁化率降低.

目的探讨脑钠肽(BNP)在协助判断肺结核合并呼吸衰竭疗效及预后的价值。方法 2013年1月—2014年12月我院收治初治菌阳肺结核合并呼衰共81例,分别在抗结核、呼衰治疗前及2周末行BNP、动脉血气分析及胸部X线检查;按住院号对应随机数字表随机抽取我院同期初治菌阳肺结核无合并呼衰104例作为对照组,采集两组数据进行回顾性病例对照研究。结果肺结核合并呼衰BNP高于单纯肺结核11.4倍(1115.11 pg/m L比97.60pg/m L),全肺结核高于非全肺结核3.4倍(1549.82 pg/m L比449.47 pg/m L)。治疗前BNP与Pa O2、Sa O2和p H值呈负相关,与Pa CO2呈正相关,治疗后两者无相关性。2周末BNP是治疗前0.57倍(632.41 pg/m L比1115.11 pg/m L),死亡组高于存活组8.7倍(3119.63 pg/m L比359.84 pg/m L)。结论肺结核合并呼衰BNP升高,治疗后随病情好转持续下降,有可能成为协助判断疗效及估测预后的指标之一。

Breast cancer is one of the world"s most urgent health problems. The first symptoms of mammary malignancies are manifested only at an advanced stage with significant mortality. Detecting this disease at an early stage gives the majority of patients a better chance of survival. The aim was to search for changes in gene expression of specific tumor vascular markers like death receptor 6 (Dr6) and glycoprotein m6B (Gpm6B) in the blood of patients with breast cancer. All subjects were divided into two groups. First group with patients are with different grades of breats tumors (n = 30). Second group consists from healthy women (n = 15). After isolation of mRNA from blood, RT-PCR was followed by gel electrophoresis. For statistical analysis one-way ANOVA was used with Student"s T test using GraphPad InStat software. Significant changes in mRNA levels of gene Dr6 in all grades of first stage breast cancer were detected. The mRNA levels of Dr6 showed a rising tendency from G1 (116% higher value than control) to G3 (198% higher than control). During monitoring of the mRNA level of Gpm6B, a weaker increase was observed than in Dr6. The difference in G1 was only 8% higher compared with controls and 44% at G3. From our results it can be concluded that DR6 is a more suitable marker for the diagnosis of breast malignancies in the early stages than Gpm6B. In our work, a non-invasive method for more timely and precise determination of the earlier stages of breast cancer is described, which could also contribute to monitoring the effectiveness of treatment, or regression of this disease.

After the digital revolution, the power system security becomes an important issue and it urges the power producers to maintain a well secured system in order to supply a quality power to the end users. This paper presents an integrated Corrective Security Constrained Optimal Power Flow (CSCOPF) with Flexible Transmission Line Impedance (FTLI) to enhance the power system security. The corrective approach of SCOPF is chosen, because it allows the corrective equipment to bring back the system to a stable operating point and hence, it offers high flexibility and better economics. The concept of FTLI arises from the ability of FACTS devices such as Thyristor Controlled Series Capacitor (TCSC), which can vary the line reactance to a certain extent. An enhanced security can be achieved by incorporating FTLI into the CSCOPF problem, since the power flow in a system is highly dependent on the line reactance. FTLI based CSCOPF can reduce the amount of rescheduling of generators, but it will result in an increased number of variables and thus, the complexity to the optimization process is increased. This highly complex problem is solved by using nonlinear programming. The AC based OPF model is preferred, since the corrective security actions require highly accurate solutions. IEEE 30 bus system is used to test the proposed scheme and the results are compared with the traditional CSCOPF. It can be seen that the proposed idea provides a notable improvement in the reduction of cost incurred for restoring the system security.
