Interest in studying individual differences （IDs） is driven by a trend characteristic of educational psychology in general and of second language acquisition （SLA） research in particular. Language learning motivation and self-determination theory （SDT） and an SDT-sub theory framework termed cognitive evaluation theory （CET） are reviewed in this article.

Language anxiety and language motivation have been studied extensively by experts in foreign language （FL） learning. Both of these constructs have been found to be closely correlated to FL achievement. In this article, the author has reviewed foreign language anxiety, language motivation and the relationship between language motivation and language anxiety.

Dear Editor Bone is the most common site for metastasis in prostate cancer(PCa),and identifying clinically useful biomarkers to predict the risk of currently incurable bone metastases is a major priority in PCa *** adenosine triphosphate(ATP)was shown to be a major biochemical constituent of the tumor microenvironment and regulates the tumor and host interactions by acting at P2 purinergic *** the P2 receptors,the ion channel P2X purinergic receptor 7(P2X7R)has an unusually long C-terminus containing 200 amino acids,which forms the molecular basis for the unique bi-function of P2X7R promoting cancer cell proliferation or inducing membrane permeabilization and apoptosis,upon activation by a low or high concentration of ATP,respectively.

In this paper, an integrated compact four-channel directly modulated analog optical transceiver is proposed and fabricated. The 3 d B bandwidth of this optical transceiver exceeds 20 GHz, and the measured spurious-free dynamic range is up to 91.2 d B · Hz^2∕3. The optical coupling efficiency(CE) is improved by using a precise submicron alignment technique for lens coupling in a transmitter optical subassembly, and the highest CE is achieved when the oblique angle of the arrayed waveguide grating using a silica-based planar lightwave circuit(AWG-PLC) in receiver optical sub assembly is set to 42°. Based on the proposed optical transceiver, we have experimentally demonstrated a 6.624 Gbit/s 4 × 4 multi-input multioutput(MIMO) 16-quadrature amplitude modulation orthogonal frequency division multiplexing(16 QAM-OFDM) radio signal over 15.5 km standard single mode fiber, together with 1.2 m wireless transmission in both an uplink and a downlink. To cope with the channel interference and noise of the fiber-wireless transmission system, a low-complexity MIMO demodulation algorithm based on lattice reduction zero-forcing(LR-ZF) is designed. In our experiment, 1.6 d B power penalty is achieved by using the proposed LR-ZF algorithm, compared to the commonly used zero-forcing ***, this LR-ZF algorithm has much less complexity than the optimal maximum-likelihood sequence estimation(MLSE) at a given transmission performance. These results not only demonstrate the feasibility of the integrated optical transceiver for MIMO fiber-wireless application but also validate that the proposed LR-ZF algorithm is effective to eliminate the interference for hybrid fiber-wireless transmission.

Application of Active Disturbance Rejection Control in Tank ...

第40届中国控制会议

作者： Wenjun Zhao Yuanqing Xia haiping song Zhongqi Sun Yifeng Xu School of Mechatronical Engineering Beijing Institute of Technology School of Automation Beijing Institute of Technology North Vehicle Research Institute

This paper develops an active disturbance rejection control（ADRC） scheme for tank gun control servo systems, aiming at achieving a high tracking precision and suppressing the influence of uncertainties on the controlled object. On the basis of tank gun system modeling, ADRC is designed for both the velocity and position tracking control loop. The unknown parameters are estimated according to bandwidth method and the performance of the ADRC is verified by numerical simulations. The results show that ADRC not only performs better than classical PID in solving tracking accuracy, but also has a good performance in anti-interference.

无人机是现代化战争的重要信息侦察手段,雾气严重影响到无人机拍摄图像的质量,对侦察识别的执行能力起到妨碍作用。为提高雾气环境下无人机航拍图像有效利用性,针对无人机航拍图像的特点及特殊应用背景,提出一种质量评价最优的无人机航拍图像去雾方法。通过将信息熵、标准差和图像傅里叶振幅3种图像质量评价参数相结合,建立图像质量综合评价函数;给定不同的大气透射率值,求解相应的去雾图像,以去雾图像的质量评价函数值作为择优标准。研究结果表明:该方法计算复杂度低、操作简单、简便易行,易于操作与实现;所获得的去雾图像视觉效果清晰、结果误差小。

目的对溶栓药物在治疗下肢深静脉血栓形成(LD-VT)中的相关问题进行探讨。方法回顾性分析我科379例行抗凝、祛聚、溶栓的综合药物治疗的LDVT患者,根据发病时期不同将患者分为急性期(≤3 d)、亚急性期(3～14 d)和慢性期(>14 d),再根据使用药物组合的不同分别将3组分为两个亚组:抗凝祛聚组和溶栓抗凝祛聚组。将158例术后发生LDVT的患者亦分为抗凝祛聚组和溶栓抗凝祛聚组。结果药物治疗对于急性期患者的治疗效果最好,在亚急性期及慢性期的两个亚组间比较,溶栓抗凝祛聚治疗的临床疗效均明显好于抗凝祛聚治疗,差异有显著性(P<0.01),两组间凝血指标及相关并发症的发生率差异无显著性。在158例术后并发LDVT患者中,溶栓抗凝祛聚治疗的效果明显好于抗凝祛聚治疗,差异有显著性(P<0.01);两组间凝血指标及相关并发症的发生率差异无显著性。结论溶栓药物对急性期LDVT患者治疗效果最好,对亚急性期和慢性期患者仍然有效。对于术后LDVT患者在严密观测下使用常规剂量溶栓药物治疗是安全有效的。
