We report a considerably promising method based on agarose gel electrophoresis （AGE） to separate single-walled carbon nanotubes by adding a water-soluble polyfluorene （w-PFO） as surfactant into the agarose gel. In this effective method, the AGE/w-PFO gel network will trap more semiconducting single-walled carbon nanotubes （SWNTs） with the assistance ofw-PFO, for the strong interaction between w-PFO and semiconducting species. The optical absorbance, photoluminescence emission and resonant Raman scattering characterization were used to ver- ify the separation effect. The purity of separated semiconducting species is as high as （98±1）%. The demonstrated field effect transistors give the on/off ratio and mobility about 27000 and 10.2 cm^2·V^-1·s^-1, respectively.

[目的]利用深度相机采集到的油桃数据在进行三维重建时,存在摄像头视野限制,导致油桃点云出现缺失的现象,严重影响油桃表型分析的准确度。为了提高油桃分级分类的准确率和工作效率,提出一种基于三维重建的油桃片外形参数估测方法。[方法]提出了一种基于真实结构的粗粒度点云生成网络(coarse-grained realistic structure with point cloud generation network,CGRSNet)。该网络首先通过编码、解码机制构建点云补全网络,通过新的采样算法对原始点云提取不同维度下的特征信息,提升油桃表型的特征提取能力,然后自解码器自上而下进行多维度点云补全,最终得到完整的油桃形状,最后用模型的参数预估模块预估油桃体积。利用多组参数构建的油桃几何模型离散成点云数据输入CGRSNet网络,得到油桃几何模型外形补全的预训练模型,再利用真实油桃点云数据对预训练模型CGRSNet做模型迁移的参数微调。[结果]该补全网络对油桃数据集补全结果的倒角距离为0.196 cm。经线性回归分析,得出体积估测的RMSE和R^(2)分数为2.47 cm^(3)和0.94,相较于PF-Net的RMSE和R^(2)分数提升约0.88 cm^(3)和0.01。[结论]本文提出的基于CGRSNet的油桃外形参数估测算法具有较好的实用性和精确度。

In this study, sea surface salinity(SSS) Level 3(L3) daily product derived from soil moisture active passive(SMAP)during the year 2016, was validated and compared with SSS daily products derived from soil Moisture and ocean salinity(SMOS) and in-situ measurements. Generally, the root mean square error(RMSE) of the daily SSS products is larger along the coastal areas and at high latitudes and is smaller in the tropical regions and open oceans. Comparisons between the two types of daily satellite SSS product revealed that the RMSE was higher in the daily SMOS product than in the SMAP, whereas the bias of the daily SMOS was observed to be less than that of the SMAP when compared with Argo floats data. In addition, the latitude-dependent bias and RMSE of the SMAP SSS were found to be primarily influenced by the precipitation and the sea surface temperature(SST). Then, a regression analysis method which has adopted the precipitation and SST data was used to correct the larger bias of the daily SMAP product. It was confirmed that the corrected daily SMAP product could be used for assimilation in high-resolution forecast models, due to the fact that it was demonstrated to be unbiased and much closer to the in-situ measurements than the original uncorrected SMAP product.

The trustworthiness and security of routing in the existing Peer-to-Peer (P2P) networks can not be ensured because of the diversity of the strategies of P2P nodes. This paper firstly uses game theory to establish game model of the strategies and profits of various types of routing nodes. Then,two incentive mechanisms for the corresponding stages of P2P trustworthy routing are proposed,namely trust associated mechanism and trust compensated mechanism. Simulation results show that the incentive mechanisms proposed in this paper will encourage cooperation actions of good nodes and restrain malicious actions of bad nodes,which ensure the trustworthiness of routing consequently.

The construction and application of novel highly efficient photocatalysts have been the focus in the field of environmental pollutant *** this work,a novel CuFe_(2)O_(4)/Bi_(12)O_(17)Cl_(2)photocatalysts were synthesized by simple hydrothermal and chemical precipitation *** fabricated CuFe_(2)O_(4)/Bi_(12)O_(17)Cl_(2)composite exhibited much higher photocatalytic activity than pristine CuFe_(2)O_(4)and Bi_(12)O_(17)Cl_(2)in the removal of bisphenol A(BPA)under visible-light illumination,which ascribed to the intrinsic p-n junction of CuFe_(2)O_(4)and Bi_(12)O_(17)Cl_(2).The photocatalytic degradation rate of BPA on CuFe_(2)O_(4)/Bi_(12)O_(17)Cl_(2)with an optimized CuFe_(2)O_(4)content(1.0 wt.%)reached 93.0%within 30 *** capture experiments of active species confirmed that the hydroxyl radicals(·OH)and superoxide radicals(·O_(2)^(-))played crucial roles in photocatalytic BPA degradation ***,the possible degradation mechanism and pathways of BPA was proposed according to the detected intermediates in photocatalytic reaction process.

背景当前,我国关于精神科护士使用保护性约束知信行的测量工具未充分考虑精神科专科特点,且测评条目繁冗,不利于推广应用,亟需更为科学的测量工具对精神科护士使用保护性约束的知信行水平进行评定。目的构建精神科护士使用保护性约束的知信行量表,并验证其信效度,为评估精神科护士使用保护性约束的知信行水平提供工具。方法基于知信行理论,通过查阅文献、访谈以及德尔菲法形成初版量表。采用分层抽样法,于2021年7月—12月,选取广东省内三级、二级和一级(含未评定等级和基层医院)各2家、共729名精神科护士为研究对象。通过项目分析、探索性因子分析、验证性因子分析形成正式量表,并采用内容效度、结构效度评价量表的效度,采用Cronbach’sα系数、重测信度、折半信度评价量表的信度。结果精神科护士使用保护性约束的知信行量表共12个条目,分为知识、信念、行为三个维度。量表水平的内容效度指数(S-CVI)为0.941,各条目的内容效度指数(I-CVI)为0.812~1.000。探索性因子分析共提取3个公因子,累计方差贡献率为62.948%。验证性因子分析结果显示模型拟合良好。量表的Cronbach’sα系数为0.887,其中知识、信念和行为维度的Cronbach’sα系数分别为0.819、0.842和0.831,量表的折半信度为0.712,重测信度为0.922。结论精神科护士使用保护性约束的知信行量表具有良好的信效度,可用于临床工作中对护理人员保护性约束知识、态度及行为的测评。

鉴定人出庭作证制度在新修改的《民事诉讼法》中已正式登场亮相。该法第78条增设了法院酌定启动鉴定人出庭作证程序和鉴定人拒不出庭的法律后果。根据证据法原理,鉴定人出庭作证程序启动应以当事人异议为主,法院酌定为辅。鉴定人拒不出庭作证应区分是否有正当理由,不应随意否定鉴定意见的证据能力,对鉴定人的制裁应适用罚款和向有关机关提出司法建议给予行政处罚。为了实现鉴定人出庭作证制度的功能,出庭费用补偿等保障制度亦应适用于证人出庭作证的相关规定,以符合制度的应有逻辑并有利于鉴定人权利之保障。
