数字经济在生产力组织方式、生产要素形式、市场主体形态等方面存在新特点,决定了打造数字经济新优势需要更加优良的新型营商环境。新业态存在市场准入困境,监管过于严苛导致数字经济存在融资难题,数据安全保障不足导致网络市场缺乏安全性与稳定性,数字经济行政纠纷解决的司法环境并不十分优良,成为打造数字经济新优势的现实挑战。优化数字经济营商环境,关键在于提高行政法治水平。应不断提升数字经济的政府立法质量,健全数字经济营商环境的良法体系。以比例原则具体化数字经济新型的包容审慎监管理念,防止产生过宽和过严两种监管极端。以安全与效率并重加快培育数据要素市场,加强反平台垄断执法,不断增强数字经济行政纠纷解决的公正高效性。

We report the discovery and characterization of a novel 112-type iron pnictide EuFeAs2, with La-doping induced superconductivity in a series of Eu1- xLaxFeAs2. The polycrystalline samples were synthesized through solid state reaction method only within a very narrow temperature window around 1073 K. Small single crystals were also grown from a flux method with the size about 100μm. The crystal structure was identified by single crystal X-ray diffraction analysis as a monoclinic structure with space group of P2 1/m. From resistivity and magnetic susceptibility measurements, we found that the parent compound EuFeAs2 shows distinct anomalies probably due to the Fe2＋ related antiferromagnetic/structural phase transition near 110K and the Eu2＋ related antiferromagnetic phase transition near 40K. La-doping suppressed both phase transitions to lower temperatures and induced superconducting transitions with a Tc - 11 K for Eu0.85La0.15FeAs2.

Apple replant disease（ARD） causes the inhibition of root system development, stunts tree growth and so on. To further investigate the effects of ARD on apple fruits, a 25-year-old apple orchard was remediated to establish a replant orchard between November 2008 and March 2009. A rotational cropping orchard was established on an adjacent wheat field. The cultivar and rootstock-scion combination used in the newly established orchards was Royal Gala/M26/Malus hupehensis Rehd. Ripe fruits were collected in mid-August 2011 and mid-August 2012, meanwhile, the following indices were measured： yield per plant; fruit weight; the fruit shape index; the contents of anthocyanin, carotenoid and chlorophyll; the soluble sugar content in the flesh; titratable acid; the sugar-acid ratio; firmness; and aroma components; apple plant ground diameter, plant height increment and the total length of the current-year shoots. The results showed that compared to rotational cropping, continuous cropping yielded statistically significant reductions in fruit weight and yield per plant of 39.8 and 76.5%, respectively. However, there were no changes in the fruit shape index. The anthocyanin and carotenoid contents decreased by 81.7 and 37.7%, respectively, while the chlorophyll content increased by 251.0%. All of these differences in content were statistically significant. The soluble sugar levels and sugar-acid ratio decreased by 25.4 and 60.9%, respectively, but the titratable acid levels and fruit firmness increased by 90.9 and 42.8%, respectively. Ten of the most important esters contributing to the apple aroma were analyzed, and the following changes were observed： hexyl acetate, butyl acetate, hexyl butyrate, acetate-2-methyl butyl, 2-methyl-hexyl butyrate, amyl acetate, butyl butyrate, 2-methyl-butyl butyrate, hexyl propionate and hexyl hexanoate decreased by 25.5, 78.4, 89.1, 55.5, 79.5, 77.2, 86.8, 69.9, 61.2, and 68.1%, respectively.

AIM: To investigate the association of lysyl oxidaselike 1(LOXL1) single nucleotide polymorphisms(SNPs)with exfoliation syndrome(XFS)/exfoliation glaucoma(XFG).METHODS: Published manuscripts from Pub Med and EMBASE were identified until May 2014. Summary odds ratios(ORs) and 95% confidence intervals(CIs) for LOXL1(rs1048661, rs2165241 and rs3825942) polymorphisms and the risk of XFS/XFG were estimated using random-or fixed- effect model.· RESULTS: The three LOXL1 polymorphisms(rs1048661, rs3825942, and rs2165241) were associated with an increased risk for XFS/XFG among Caucasians,with OR 2.19(1.96-2.45), 8.8(6.05-12.79) and 3.41(3.11-3.73), respectively. On the contrast, the rs1048661 and rs2165241, but not rs3825942 polymorphism, have a potential protective effect on XFS/XFG in Asians, with OR0.06(0.02-0.18), 0.15(0.09-0.25), ***: There is strong evidence that LOXL1 polymorphisms are associated with XFS/XFG risk. The strength of risk might be ethnicity-dependent.

电流体动力(EHD)等离子体发生器产生的常压等离子体可把电能转化为周围气体的动能,从而加速表面气流的流动。目前EHD等离子体发生器能量转化的具体物理过程仍没有得到合理解释而等离子体发生器的沿面闪络问题亦制约着其性能的进一步提高。本文分别测量了对称结构EHD等离子体发生器在空气和氮气环境下的电气和EHD特性,讨论分析了EHD等离子体发生器的能量转化过程。实验结果表明对称结构EHD等离子体发生器可工作在"推"模式下,且负离子在能量转化过程中似乎起到重要的推动作用。另外,本文研究了表面封装对等离子体发生器沿面闪络的影响。实验结果表明封装后等离子体发生器的沿面闪络得到明显抑制。
