Yang and Chang (2009) proposed a three-party authenticated key exchange protocol for securing communications in mobile-commerce environments. Their protocol reduces computation and communication costs by employing elliptic curve cryptosystems. However, Tan (2010) pointed out that Yang and Chang (2009)'s protocol cannot withstand impersonation and parallel attacks, and further proposed an enhanced protocol to resist these attacks. This paper demonstrates that Tan (2010)'s approach still suffers from impersonation attacks, and presents an efficient and secure three-party authenticated key exchange protocol to overcome shown weaknesses.

As the fiat panel displays （Liquid Crystal Displays, AMOLED, etc.） reach near perfection in their viewing qualities and display areas, it is natural to seek the next level of displays, including 3D displays. There is a strong surge in 3D liquid crystal displays as a result of the successful movie Avatar. Most of these 3D displays involve the employment of special glasses that allow one view perspective for each of the eyes to achieve a depth perception. Such displays are not real 3D displays. In fact, these displays can only provide one viewing perspective for all viewers, regardless of the viewer＇s position. In addition, a fundamental viewing problem of focusing and accommodation exist that can lead to discomfort and fatigue for many viewers. In this paper, the authors review the current status of stereoscopic 3D displays and their problems. The authors will also discuss the possibility of using fiat panels for the display of both phase and intensity of video image information, leading to the ultimate display of 3D holographic video images. Many of the fundamental issues and limitations will be presented and discussed.

随着全球经济一体化的快速发展,各国经济发展和外界因素之间形成了紧密的关系。国际贸易开放可以促进本国经济的发展和产业结构的调整,但是同时也给本国经济运行带来风险。非洲国家经济结构单一,工业化水平普遍较低,经济增长主要依赖原材料出口、入境旅游等,贸易对外依存度高。本研究关注贸易开放度对经济增长的影响,对非洲经济社会发展具有重大而深远的意义,为维护多边主义和自由贸易、建设非洲开放型经济发展模式提供基础。本研究从非洲各国参与全球贸易一体化的多个视角构建衡量贸易开放水平的指标体系,从而明确贸易开放对非洲经济增长的影响。具体而言,文章采用四种衡量标准确定贸易开放度:贸易总额与GDP的比率(OPEN1)、出口与GDP的比率(OPEN2)、进口与GDP的比率(OPEN3)以及综合效应指数(OPEN4)。本文基于2000-2018年52个非洲国家的平衡面板数据,使用普通最小二乘法、固定效应法和的系统广义矩估计法进行实证分析。结果显示:(1)POLS表明贸易开放对经济增长具有混合影响。具体而言,OPEN1、OPEN3和OPEN4对经济增长具有积极影响,而OPEN2对经济增长产生负面影响。将非洲细分为不同区域,贸易开放度与人均GDP呈非线性关系,北非的结果在经济增长方面是稳健的。(2)根据固定效应模型,贸易开放(OPEN1和OPEN2)对人均GDP具有负向的影响效应,OPEN3和OPEN4对GDP的影响不显着。(3)系统GMM结果说明贸易开放度在各种开放性度量和稳健性回归估计中缺乏弹性。(4)格兰杰因果检验拒绝了贸易开放度指标、劳动力、金融发展、外国直接投资、消费者价格指数、汇率与非洲人均GDP无格兰杰因果关系的原假设。然而,只有总资本形成并不能提高非洲的人均GDP水平。进一步研究结果表明,进口抑制了增长,而出口促进了非洲的增长。根据上述研究结果,本研究提出政府应该推行新的结构性经济政策,鼓励出口扩大,促进经济增长。在具体国别政策中,建议苏丹、中非、布隆迪和埃塞俄比亚增强吸引援助、完善投资环境、主动促进农村发展和技术进步。此外,上述国家应该在非洲地区经济发展中发挥更加明显的增长溢出效应和经济带动效应。

Objective: To identify the influences of local and regional climate phenomena on dengue transmission in Lahore District of Pakistan, from 2006 to 2014. Methods: Time-series models were applied to analyze associations between reported cases of dengue and climatic parameters. The coherence trend of regional climate phenomena(IOD and ENSO) was evaluated with wavelet analysis. Results: The minimum temperature 4 months before the dengue outbreak played the most important role in the Lahore District(P=0.03). A NINO 3.4 index 9 months before the outbreaks exhibited a significant negative effect on dengue transmission(P=0.02). The IOD exhibited a synchronized pattern with dengue outbreak from 2010 to 2012. The ENSO effect(NINO 3.4 index) might have played a more important role after 2012. Conclusions: This study provides preliminary results of climate influences on dengue transmission in the Lahore District of Pakistan. An increasing dengue transmission risk accompanied by frequent climate changes should be noted. Integrating the influences of climate variability into disease prevention strategies should be considered by public health authorities.

An inverted pendulum is a sensitive system of highly coupled parameters, in laboratories, it is popular for modelling nonlinear systems such as mechanisms and control systems, and also for optimizing programmes before those programmes are applied in real situations. This study aims to find the optimum input setting for a double inverted pendulum（DIP）, which requires an appropriate input to be able to stand and to achieve robust stability even when the system model is unknown. Such a DIP input could be widely applied in engineering fields for optimizing unknown systems with a limited budget. Previous studies have used various mathematical approaches to optimize settings for DIP, then have designed control algorithms or physical mathematical *** study did not adopt a mathematical approach for the DIP controller because our DIP has five input parameters within its nondeterministic system model. This paper proposes a novel algorithm, named Uni Neuro, that integrates neural networks（NNs） and a uniform design（UD） in a model formed by input and response to the experimental data（metamodel）. We employed a hybrid UD multiobjective genetic algorithm（HUDMOGA） for obtaining the optimized setting input parameters. The UD was also embedded in the HUDMOGA for enriching the solution set, whereas each chromosome used for crossover, mutation, and generation of the UD was determined through a selection procedure and derived individually. Subsequently, we combined the Euclidean distance and Pareto front to improve the performance of the algorithm. Finally, DIP equipment was used to confirm the settings. The proposed algorithm can produce 9 alternative configured input parameter values to swing-up then standing in robust stability of the DIP from only 25 training data items and 20 optimized simulation results. In comparison to the full factorial design, this design can save considerable experiment time because the metamodel can be formed by only 25 experiments using the UD. Furth

The objective of this study was to investigate the spatial relationship between the most likely distribution of saturated hydraulic conductivity(Ks) and the observed pressure head(P) distribution within a hillslope. The cross-correlation analysis method was used to investigate the effects of the variance of ln Ks, spatial structure anisotropy of ln Ks, and vertical infiltration flux(q) on P at some selected locations within the hillslope. The cross-correlation analysis shows that, in the unsaturated region with a uniform flux boundary, the dominant correlation between P and Ksis negative and mainly occurs around the observation location of P. A relatively high P value is located in a relatively low Kszone, while a relatively low P value is located in a relatively high Kszone. Generally speaking, P is positively correlated with q/Ksat the same location in the unsaturated region. In the saturated region, the spatial distribution of Kscan significantly affect the position and shape of the phreatic surface. We therefore conclude that heterogeneity can cause some parts of the hillslope to be sensitive to external hydraulic stimuli(e.g., rainfall and reservoir level change), and other parts of the hillslope to be insensitive. This is crucial to explaining why slopes with similar geometries would show different responses to the same hydraulic stimuli, which is significant to hillslope stability analysis.

The Chouchani lab recently reported in Nature that a dynamic intracellular lactate is a physiological regulator for cell cycle *** also showed that accumulated lactate in cell mitosis directly binds and inhibits Sentrin/SUMO-specific pro-tease 1 to enrich SUMO2/3-modification of anaphase-promot-ing complex 4(APC4),which promotes the degradation of APC/C complexes,leading to mitosis exit.
