提高客户忠诚度,提升商业银行关系营销质量

市场经济体制改革的不断深入,国有商业银行的外部环境主要呈现出以下新特点:政策分流日益严重,如国家刺激消费、拉动需求的政策,对社会资金产生较强的吸引力;存贷款利率持续维持低水平状态,增加了存款的流动性,加剧了存款分流

国家自然科学基金2001-2016年基于纳米技术相关研究的资助项目分析

目的为我国从事纳米技术,特别是纳米医学相关研究人员提供参考。方法对国家自然科学基金委员会在2001～2016年资助纳米技术相关项目的基本情况进行了总结。结果与结论纳米技术是研究结构尺寸在1～100 nm内材料的性质和应用的一种技术,在材料与制备,微电子和计算机技术,医学与健康,航天和航空,生物技术等多个方面具有广泛的应用前景,是跨学科的重要科技前沿,但目前在国内获得临床许可或上市的纳米医学相关产品十分匮乏,这与目前国内数量庞大的纳米领域论文发表与科研经费不成正比

阶梯电价机制下居民用电中期负载预测研究

实行阶梯电价已成为缓解我国能源供应紧缺、资源交叉补贴不合理等矛盾的重要举措。准确地刻画阶梯电价下的动态用户需求,有利于提高负载预测准确度。拟从现行递增阶梯电价动态需求的特征出发,提出一个新的分类负载预测模型。首先通过模糊聚类分析对某地区居民用电行为进行聚类;然后针对不同用户类别进行数据分类,再分别建立基于自组织模糊神经网络的负载预测模型;最后对各个模型进行加总。通过某地区实际居民数据检验,验证了分类负载预测模型的有效性。相比于传统的单一模型,新分类模型的预测准确度得到了提高,进一步保证了电网公司为居民提供高质稳定的供电服务,同时帮助降低了电网公司的运营成本,提高了经济效益。国家自然科学基金(71301133);; 教育部人文社会科学研究项目(13YJC630033

Ambient stable large-area flexible organic solar cells using silver grid hybrid with vapor phase polymerized poly (3,4-Ethylenedioxythiophene) cathode

The presence of PSS in solution processed high conducting polymer PEDOT:PSS (PH1000) limits the reliability and lifetime of organic photovoltaic devices due to its acidic and hygroscopic nature. We have developed an alternative PSS-free transparent electrode, based on vapor-phase polymerized (VPP) PEDOT in combination with a current collecting silver grid. The hybrid electrode exhibits a low sheet resistance of 1.6 Omega/square with an excellent bending proof performance. The power conversion efficiency (PCE) is 2.63% in a 1.21 cm(2) area device with a stacking structure of PET/Ag-grid/VPP-PEDOT/ZnO/poly[(9,9-bis(3-(N,N-dimethylamino)propyl)-2,7-fluorene)-alt-2,7-(9,9-dioctylfluorene)](PFN)/poly(3-hexylthiophene):[6,6]-phenyl-C61 butyric acid methyl ester (P3HT:PC61BM)/MoO3/Al. This efficiency is lower than, but comparable to the PCE (3.36%) of a control device with similar structure PET/Ag-grid/PH1000/ZnO/PFN/P3HT:PC61BM/MoO3/Al. A striking advantage using VPP-PEDOT to replace PH1000 is the high ambient stability of the device. The PCE of un-encapsulated devices after 120 h continuous exposure to ambient oxygen and moisture is retained at a 75% level of its initial value. These results suggest that the Ag grid/VPP-PEDOT is a promising alternative to ITO or high conducting PEDOT:PSS for realization of high efficiency, low cost and stable organic solar cells (OSCs).

JUNO Sensitivity on Proton Decay p→νˉK+p\to \bar\nu K^+ Searches

The Jiangmen Underground Neutrino Observatory (JUNO) is a large liquid scintillator detector designed to explore many topics in fundamental physics. In this paper, the potential on searching for proton decay in $p\to \bar\nu K^+$ mode with JUNO is investigated.The kaon and its decay particles feature a clear three-fold coincidence signature that results in a high efficiency for identification. Moreover, the excellent energy resolution of JUNO permits to suppress the sizable background caused by other delayed signals. Based on these advantages, the detection efficiency for the proton decay via $p\to \bar\nu K^+$ is 36.9% with a background level of 0.2 events after 10 years of data taking. The estimated sensitivity based on 200 kton-years exposure is $9.6 \times 10^{33}$ years, competitive with the current best limits on the proton lifetime in this channel

JUNO sensitivity on proton decay p → ν K + searches*

The Jiangmen Underground Neutrino Observatory (JUNO) is a large liquid scintillator detector designed to explore many topics in fundamental physics. In this study, the potential of searching for proton decay in the $p\to \bar{\nu} K^+$ mode with JUNO is investigated. The kaon and its decay particles feature a clear three-fold coincidence signature that results in a high efficiency for identification. Moreover, the excellent energy resolution of JUNO permits suppression of the sizable background caused by other delayed signals. Based on these advantages, the detection efficiency for the proton decay via $p\to \bar{\nu} K^+$ is 36.9% ± 4.9% with a background level of $0.2\pm 0.05({\rm syst})\pm$$0.2({\rm stat})$ events after 10 years of data collection. The estimated sensitivity based on 200 kton-years of exposure is $9.6 \times 10^{33}$ years, which is competitive with the current best limits on the proton lifetime in this channel and complements the use of different detection technologies
