Using inclusive decays of J/ψ aprecise determination of the number of J/ψ events collected with the BESIII detector was *** the two data sets taken in 2.09 and 2.12.the numbers of J/ψ events were recalculated to be(2.4.0±1.3)×10^(6) and(1088.5±4.4)×10^(6),respectively;these numbers are in good agreement with the previous measurements. For the J/ψ sample taken in 2.17-2.19,the number of events was determined to be(8774.0±39.4)×10^(6).The total number of J/ψ events collected with the BESIII detector was determined to be(10087±44)×10^(6),where the uncertainty is dominated by systematic effects,and the statistical uncertainty is negligible.

根据假单胞菌16S rDNA基因序列设计引物,并向反应体系中加入饱和型核酸染料Eva Green,利用实时荧光检测仪,建立假单胞菌属实时荧光环介导等温扩增技术(LAMp)。研究中对62.假单胞菌的16SrDNA基因通过DNAMAN软件进行序列比对后,针对共有片段设计扩增引物。对扩增体系进行了优化,优化结果经电泳鉴定。通过12.假单胞菌和2.株非假单胞菌进行特异性验证,并比较了实时荧光LAMp与普通LAMp的灵敏度,对人工污染样品的检出限进行了测定。结果表明,特异性验证中12.假单胞菌为阳性,2.株非假单胞菌为阴性。实时荧光LAMp检测纯菌的灵敏度为36 CFU/mL,是普通LAMp灵敏度的10倍。人工污染样品的检出限为1.73×10^3 CFU/g。本研究中建立了一种检测冷鲜猪肉中假单胞菌属的方法,实现了多个菌种的同时检测,避免了单一菌种检测的局限性,该方法快速、准确、灵敏度高,可在2.内完成冷鲜猪肉中假单胞菌的检测。

【目的】解决多层次社交网络链接分类算法无法有效获取各层次间子网络的关联信息,从而提高分类性能的问题。【方法】定义反映各子网络间关联的共性特征和反映各子网络自身属性结构的特性特征,提出一种基于迁移成分分析的多层次社交网络链接分类算法,获取反映层次间相互关联特征的组件,使得不同层次的子网络能够相互学习。【结果】通过在真实多层次数据集you Tube和Query Log上与基准分类算法、基于特征学习的分类算法和基准迁移分类算法进行比较,在AUC和rOC曲线的评价指标上有1.57%-33.2.的提升。【局限】未能处理超大规模的网络数据,同时尚未深入探讨特征定义的维度和性能之间的关系。【结论】本文方法能够有效地将迁移学习思想应用到多层次社交网络链接分类场景,为该类模型的研究提供一种新的方案。

本文构建了刻画乡村农户贫困状态的特征因子的提取算法和分析框架,旨在实现和帮助完善家庭农场的持续发展,尤其是由贫困农户组成或参与的家庭农场在发展需要的融资方面的乡村信用评估,推动有效地制订对应政策和落地方案,巩固脱贫攻坚成果和防止返贫。本文的最大亮点是以“分类与回归树”(CArT)分析和“吉布斯抽样”(Gibbs Sampling)的人工智能算法为工具,对乡村农户贫困状态的特征因子提取建立了对应的框架和分析流程。基于国内某地区乡村建档立卡数据库的31,116个样本,实证研究筛选出12.刻画乡村农户贫困状态高度关联的特征因子,并进一步对特征因子的有效性进行了rOC曲线和AUC测试。结果表明以特征因子分析框架为基础,建设配套的乡村信用评估体系是支持乡村振兴的可持续性最佳解决途径之一,除了能够为乡村贫困户获得持续工作的基本技能或生产环境的改善提升上得到持续性的融资支持提供评估依据和数据支持,也能为乡村和城镇“传帮带”等生产和商务平台的建立提供可持续的基础性数据和信用分析的动态支持。

典型岩溶丘陵区生长季土壤CO_2.CH_4通量研究

我国西南岩溶丘陵区生长季漫长,而土壤表面CO_2.CH_4通量受地表植被覆盖的影响较大。为探究岩溶丘陵区生长季有植被覆盖(有草)和无植被覆盖(无草)的土壤表面CO_2.CH_4通量及其日变化特征,采用静态箱-气相色谱法对重庆市南川岩溶丘陵区土壤表面CO_2.CH_4通量进行观测,结合土壤温、湿度进行研究。结果表明:岩溶丘陵区土壤表面在生长季表现为CO_2.、CH_4汇,有草的土壤表面CO_2.量明显高于无草土壤表面CO_2.量,CH_4通量则无明显差别,说明在生长季地表植被覆盖是影响土壤CO_2.量的重要因素,而植被覆盖对土壤CH_4通量无显著影响,土壤表面有草和无草的CO_2.量分别为552.352.mg/m2.h,CH_4通量分别为-80、-75μg/m2.h(生长季6个月平均值)。在生长季日变化尺度上,土壤也表现为CO_2.、CH_4汇,有草土壤表面的CO_2.量明显高于无草土壤表面CO_2.量,且二者的变化特征一致,CH_4通量受到植被覆盖的影响较小;生长季土壤CO_2.CH_4通量受土壤温、湿度的共同影响,其中土壤CO_2.量与土壤温度呈正相关关系,即土壤温度升高会促进土壤CO_2.量的提高,而土壤CH_4通量与土壤温度无相关关系,即土壤温度对土壤CH_4通量无显著影响;由于生长季土壤湿度变化较土壤温度小,因此土壤湿度对土壤CO_2.CH_4通量的影响较土壤温度小。
