Distribution. China (Zhejiang, Anhui). Remarks. The primary types of this species cannot currently be found. The types were collected from Mt. Gutianshan, Zhejiang, on August 2, 1992. The specimens herein examined were collected from adjacent areas near the type locality of I. dictyophilum and show identical morphological characters to that in type specimens (see Yang & Liu 1995), which thereby confirmed our identification of this species as I. dictyophilum. Yang & Liu (1995) noted that this species is usually attracted by the Malaise trap but the females are rarely collected. All specimens we examined were males and no female specimens were available for our study.Published as part of Li, Di, Aspöck, Horst, Aspöck, Ulrike & Liu, Xingyue, 2018, A review of the beaded lacewings (Neuroptera: Berothidae) from China, pp. 235-257 in Zootaxa 4500 (2) on pages 246-248, DOI: 10.11646/zootaxa.4500.2.5, http://zenodo.org/record/529757

Bringing big data analytics in accounting into classrooms: A case combing XBRL data and high-performance computing (HPC) resources
No full text3rd OAK Supercomputing Conference, Wichita State University, May 20-24, 2024.
Research presented on May 23, 2024.See abstract here: https://www.wichita.edu/services/hpc/oaksupercompute2024/oak_abstracts.phpBig data analytics is the process of collecting, processing, and analyzing large and complex data sets to extract valuable insights and support decision making. Despite the critical importance of big data analytics skills in this age when data volume is experiencing explosive growth, very few accounting programs teach big data analytics effectively. To help students gain knowledge and experiences of applying big data analytics in accounting, we developed a case for financial misreporting detection using multiple large real-world financial statement datasets based on eXtensible Business Reporting Language (XBRL). To deal with the challenges of high requirements on computer resources for efficiently sharing and processing large XBRL formatted data, we take advantage of High-Performance Computing (HPC) resources that can be accessed by educators and students easily for free at most universities and other public research institutions. Through this case, students will learn about XBRL concepts such as extension taxonomies and how to use free and popular tools such as Python to process and analyze XBRL data. They will learn how to read in large raw data sets, extract financial line items, transform the data, and perform basic data analysis such as descriptive statistics and data visualization for the distribution of earnings and other financial line items that can indicate potential financial misreporting cases. This approach will equip accounting students who have little or no statistical background and programming skills with basic big data analytics skills for detailed financial data analysis
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Intrinsic Mechanisms of Morphological Engineering and Carbon Doping for Improved Photocatalysis of 2D/2D Carbon Nitride Van Der Waals Heterojunction
No full textPublished May 2023Van der Waals (VDW) heterojunctions in a 2D/2D contact provide thehighest area for the separation and transfer of charge carriers. In this work, atop-down strategy with a gas erosion process was employed to fabricate a2D/2D carbon nitride VDW heterojunction in carbon nitride (g-C3N4) withcarbon-rich carbon nitride. The created 2D semiconducting channel in theVDW structure exhibits enhanced electricfield exposure and radiationabsorption, which facilitates the separation of the charge carriers and theirmobility. Consequently, compared with bulk g-C3N4and its nanosheets, thephotocatalytic performance of the fabricated carbon nitride VDWheterojunction in the water splitting reaction to hydrogen is improved by 8.6and 3.3 times, respectively, while maintaining satisfactory photo-stability.Mechanistically, thefinite element method (FEM) was employed to evaluateand clarify the contributions of the formation of VDW heterojunction toenhanced photocatalysis, in agreement quantitatively with experimental ones.This study provides a new and effective strategy for the modification andmore insights to performance improvement on polymeric semiconductors inphotocatalysis and energy conversion.Jinqiang Zhang, Xiaoli Zhao, Lin Chen, Shuli Li, Haijun Chen, Yuezhao Zhu, Shuaijun Wang, Yang Liu, Huayang Zhang, Xiaoguang Duan, Mingbo Wu, Shaobin Wang, and Hongqi Su
