The treatment of pathological fractures of the femoral neck and trochanteric region secondary to benignlesions can be a challenge for orthopaedic surgeons because of the size and nature of the lesions, the resulting bony defect, the risk of recurrence, the possible associated deformities, and the risk of osteonecrosis. Numerous treatment modalities have been reported for the management of pathological fractures of the proximal femur secondary to benign lesions. An unsatisfactory outcome in 25% of patients and a complication rate of 45% have been observed.

The paper describes a new ultrasonic measurement technology that evaluates a spray nozzle cooling characteristics based on measured time-of-flight data using an electromagnetic ultrasonic transducer（EMAT）. A spiral electromagnetism ultrasonic transducer was used to measure the ultrasonic velocity dependence of temperature in a certain thickness metal plate. The instantaneous time-of-flight time data were used to determine the velocity and deduce the interior and surface temperature. To verify the validity of the ultrasonic measurement result, one-dimensional unsteady heat transmission equation is established to compute the heat transfer coefficients（HTC） theoretically compared with ultrasonic measurement results. Through some one-dimensional analysis, this work will show that the HTC is a natural and stable quantity to estimate ultrasonic time of flight measurements.

Sustainable polyurethanes prepared from castor oil and diisocyanates show very low strength and toughness, due to the highly cross-linked and flexible structure. Herein, we report a new strategy to simultaneously reinforce and toughen castor oil-based polyurethane via incorporating a stiff component （isosorbide, IS） to enhance network stiffness and reduce crosslink density. The crosslinking degree de- creases while the strength, moduli, ductility and heat re- sistance significantly increase accordingly with increasing IS content. The tensile behaviors are tunable over a broad range （either as elastomers or as plastics） depending on the com- positions. The polyurethanes show excellent thermal stability with onset decomposition temperature higher than 280℃. The investigation provides a new hint for future design and fab- rication of high performance sustainable polymers from other vegetable oils.

研究长江经济带省际贸易网络结构,有利于揭示其内部经济联系规律,推进区域经济协同发展。基于2000-2015年省际铁路货运交流数据,采用SNA方法刻画长江经济带省际贸易网络时空特征,借助贸易网络引力模型和QAP回归方法实证研究省际贸易网络演变的影响因素。研究表明:(1)2000-2015年长江经济带省际贸易网络结构发生了显著变化,逐步演化成"苏-浙-皖-赣"和"川-渝-滇-贵"两大贸易联系核心圈;(2)网络密度呈现先升后降的弱连结联系态势,圈层特征明显,子圈间联系较弱;(3)中心性水平呈现"下冷中上热"态势,各贸易主体影响力日趋均衡,但点出入度非均衡趋势明显;(4)城镇化、产业结构、基础设施、地方保护是长江经济带省际贸易网络演变的重要因子。建议:着力构建区域联动的新型城镇化格局、适时产业结构调整、加快基础设施互联互通、建立跨区域联合协调机制,以深化地区间经济联系。

城镇化对全面建设社会主义现代化国家意义重大,是我国最大的内需潜力和发展动能所在。近年来,我国城镇化水平快速提高,党中央、国务院就深入推进新型城镇化建设作出了一系列重大决策部署。在推进城镇化进程中,民族地区独有的地理位置、风俗传统和人口结构,决定着其城镇化实施的特殊性,以及地方政府的价值表现。从认同理性、规制理性、要素理性等角度坐实政府的价值理性,是政府从主导者变引导者,从输血者变造血者的积极行动,也是促进东西部城镇化建设的均衡发展,保证自上而下的国家战略有序实施的重要举措。

文章在分析交通基础设施对城镇化发展影响机制基础上,首先采用Moran指数对中部地区地级市经济增长的空间相关性进行检验,结果表明中部地区地级城市经济增长之间存在显著的空间依赖性,进而分别建立空间滞后模型(SLM)和空间误差模型(SEM),对中部地区交通基础设施对城镇化发展的空间效应进行实证分析。结果表明:交通基础设施促进了中部地区城镇化发展,但通过与普通计量回归模型结果进行对比发现,忽视空间因素的影响,交通基础设施对城镇化的推动作用存在高估现象,此外,在影响地区城镇化发展的其他因素中,非农产业发展起到突出作用;而考虑了空间因素后,土地扩张对城镇化的拉动作用也进一步降低。

Comparison on Seed Production of Various Orchardgrass

第26届中国控制与决策会议

作者： Hong-bing zeng Shen-Ping Xiao Chang-Fan Zhang Gang Chen School of Electrical and Information Engineering Hunan University of Technology

This paper deals with the problem of passivity analysis for neural networks with both time-varying delay and norm-bounded parameter uncertainties. By further utilizing the information of activation function and employing a reciprocally convex approach to consider the relationship between the time-varying delay and its time-varying interval, some improved delay-dependent passivity conditions are obtained, which are formulated in terms of linear matrix inequalities(LMIs) and can be readily solved by existing convex optimization algorithms. Finally, a numerical example is provided to verify the effectiveness of the proposed techniques.

关键词： Neural networks passivity delay-dependent Lyapunov-Krasovskii functional linear matrix inequalities(LMIs).
