LinkingPark: An automatic semantic table interpretation system

In this paper, we present LinkingPark, an automatic semantic annotation system for tabular data to knowledge graph matching. LinkingPark is designed as a modular framework which can handle Cell-Entity Annotation (CEA), Column-Type Annotation (CTA), and Columns-Property Annotation (CPA) altogether. It is built upon our previous SemTab 2020 system, which won the 2nd prize among 28 different teams after four rounds of evaluations. Moreover, the system is unsupervised, stand-alone, and flexible for multilingual support. Its backend offers an efficient RESTful API for programmatic access, as well as an Excel Add-in for ease of use. Users can interact with LinkingPark in near real-time, further demonstrating its efficiency.     

Combination of nuclear magnetic resonance spectroscopy and nonlinear methods to analyze the copolymerization of phosphonic acid derivatives

We demonstrate in this study that the combination of modern inline monitoring methods [here: inline nuclear magnetic resonance (NMR)] with simulations gains more exact and profound kinetic results than previously used methods like linearization without that combination. The ¹H-NMR spectroscopic data (more than 100 data points) are used to construct the copolymerization diagram. The reactivity ratios are obtained applying the van Herks nonlinear least square method. The examination of the radical copolymerization of 2-hydroxyethyl methacrylate (HEMA) with (2-{[2-(ethoxycarbonyl)prop-2-en-1-yl]oxy}ethyl) phosphonic acid (ECPPA) as important adhesive monomer used in dentistry yields reactivity ratios of r_HEMA = 1.83; r_ECPPA = 0.42. The copolymerization diagram reflects nonideal, non-azeotropic copolymerization. The sequence distribution of the obtained by Monte Carlo simulation indicates the generation of statistical copolymers. As an important finding, it is demonstrated that the repeating units responsible for etching and adhesion are arranged over the whole polymer chain, which is necessary to achieve proper functionality. © 2019 Wiley Periodicals, Inc.

超深防渗帷幕降水减压作用研究

采用有限元法分析了武汉阳逻长江大桥南锚碇工程在不同降水深度下防渗帷幕和地连墙的受力特性。计算结果表明,只要选择合适的帷幕材料并控制相应的施工参数,水头差对帷幕影响不大。降水超过一定深度后,效果并不明显,即存在一个临界降水深度和降水影响深度,与帷幕和地连墙的距离及土质有关。     

基于城市化角度的增减挂钩政策实施研究

2003年以来,我国推行了城乡建设用地增减挂钩的政策。本文重点研究了增减挂钩政策实施中两条典型的路径:宅基地换房和"双置换",并基于城市化道路研究的角度指出了华明镇宅基地换房的制度创新和"双置换"的危害和教训,并进一步总结了增减挂钩政策的适用性。如何妥善解决千差万别的农民的城市化,需要通过因时而异、因地而异的方式来实现,当前一些地方在增减挂钩试点中一刀切的、不研究地方实际的城市化道路是断不可取的。

提高完井电测一次成功率的钻井液技术对策

近年来,随着油气勘探开发的深入,大斜度井、水平井的增多,定向井及水平井位移越来越长,遇阻通井现象频频发生,完钻电测一次成功率低,影响了建井周期。本文通过对川西、川东北等地区部分定向井及水平井完井电测遇阻原因分析,从钻井液角度出发,提出"强抑制-交联-固壁"技术、高效润滑段塞技术等相应对策提高电测一次成功率。现场应用表明,这些钻井液技术对策为提高完井电测一次成功率、解决电测遇阻问题提供了新的思路。

光固化复合电泳涂层材料的制备及其传感性能

目的 研究电泳沉积条件及光交联对氧化石墨烯与胶束共沉积制备的生物传感涂层形貌、性能的影响。方法 首先通过光敏单体甲基丙烯酸羟乙酯（HEMA）改性生物大分子γ-聚谷氨酸制备可光交联的大分子γ-PGA-HEMA。然后,将光敏大分子与辣根过氧化酶（HRP）在溶液中静电自组装制备功能性纳米粒子溶液,利用纳米粒度分析仪、透射电子显微镜（TEM）对纳米粒子的粒径和形貌进行表征。随后,诱导复合纳米组装体与前驱体氧化石墨烯（GO）共组装制备多组分复合沉积液。最后,在上述复合沉积液的基础上进行电化学还原GO,控制不同沉积条件,通过电泳沉积法在玻碳电极表面制备具有特异性识别功能的生物传感涂层,利用扫描电子显微镜（SEM）、电化学工作站等研究了电泳沉积条件及光交联对涂层形貌及性能的影响。结果 当沉积电压为1.5 V,沉积时间为120 s,GO质量浓度为0.1 mg/mL时,电泳沉积制备的涂层表面光滑,具有较好的致密性和均一性。光交联后,涂层的致密性和稳定性进一步提高,此时该涂层对过氧化氢（H2O2）具有良好的电流响应。结论 电泳沉积复合共组装胶束制备光交联涂层过程中,沉积时间、沉积电压、GO含量均存在最优值,最优值下制备的涂层结构完整,致密性最好。光交联可进一步提高涂层的稳定性,生物传感性能最好。
