A patterned polymer dispersed liquid crystal transparent display using one-time UV exposure is demonstrated.The device is fabricated by exposing the cell with a uniform UV light through a mask with selective attenuation of the UV light.The voltage-transmittance response of the device is different for the corresponding regions.Thus,three different states of total scattering,patterned transparent,and total transparent can be realized by controlling the applied voltages.The proposed device used in shutter mode as smart windows and in projected display mode is demonstrated,which shows great potential for smart windows with customized patterns or Iogos and has potential application in the field of projected transparent displays.

利用2017年我国最新流动人口动态监测数据和278个城市数据的匹配数据,考察了城乡居民医保参与对自雇流动人口城市融入的影响.研究发现,城乡居民医保参与会显著提升自雇流动人口城市融入.为克服实证模型的内生性问题和选择性偏误,运用TEM模型和CMP方法进行回归,并结合倾向得分匹配方法(PSM)构造反事实框架,纠正可能的选择性偏误,所得结果依然支持城乡居民医保参与对自雇流动人口城市融入的正向影响效应.分位数回归结果显示,城乡居民医保参与对中等城市融入度的自雇流动人口影响最大.样本异质性分析发现,城乡居民医保参与
基于2004-2016年中国271个地级市的面板数据,构建动态面板门槛模型,探究环境规制对技术创新影响绿色全要素能源效率的非线性效应.结果 显示:技术创新能够显著提升绿色全要素能源效率,且这种提升作用存在门槛特征,在环境规制处于门槛值以上时,提升作用较大.技术创新直接通过绿色技术创新效应、间接通过经济增长效应、产业结构升级效应、外商直接投资效应等影响绿色全要素能源效率,并且只有当环境规制水平超过门槛值时,间接影响机制才有效.中国每年越过环境规制门槛值的城市数量逐年递增,但是仍有少量城市在样本期内未跨越门槛

智慧治理作为新时代背景下社会治理与信息化技术深度融合的产物,在实践中不断提升着治理的效能和质量.以数字化、智能化等应用信息技术为核心的技术突破,在重塑治理结构的同时亦改变了传统的制度规范.当前智慧治理能力建设过程中存在技术应用缺乏透明度、布局缺乏统筹性、执行缺乏权宜性等技术失控问题,还存在权力结构失衡、话语结构固化、行动结构分散等结构失当问题,以及实体规范缺失及虚拟规范难以适用等制度失准问题.建议通过完善技术设计规划、优化建设结构布局及构建系统规约制度等路径,强化智慧治理能力建设.
