Web-based libraries,such as D3.js,ECharts.js,and G6.js,are widely used to generate node-link graph visualizations.These libraries allow users to call application programming interfaces(APIs)without identifying the details of the encapsulated techniques such as graph layout algorithms and graph rendering methods.Efficiency requirements,such as visualizing a graph with 3k nodes and 4k edges within 1 min at a frame rate of 30 fps,are crucial for selecting a proper library because libraries generally present different characteristics owing to the diversity of encapsulated techniques.However,existing studies have mainly focused on verifying the advantages of a new layout algorithm or rendering method from a theoretical viewpoint independent of specific web-based libraries.Their conclusions are difficult for end users to understand and utilize.Therefore,a trial-and-error selection process is required.This study addresses this gap by conducting an empirical experiment to evaluate the performance of web-based libraries.The experiment involves popular libraries and hundreds of graph datasets covering node scales from 100 to 200k and edge-to-node ratios from 1 to 10(including complete graphs).The experimental results are the time costs and frame rates recorded using the libraries to visualize the datasets.The authors analyze the performance characteristics of each library in depth based on the results and organize the results and findings into application-oriented guidelines.Additionally,they present three usage cases to illustrate how the guidelines can be applied in practice.These guidelines offer user-friendly and reliable recommendations,aiding users in quickly selecting the desired web-based libraries based on their specific efficiency requirements for node-link graph visualizations. 展开更多

High-density genetic markers are required for genotyping and linkage mapping in identifying genes from crops with complex genomes, such as barley. As the most common variation, single nucleotide polymorphisms(SNPs) are suitable for accurate genotyping by using the next-generation sequencing(NGS) technology. Reduced representation libraries(RRLs) of five barley accessions and one mutant were sequenced using NGS technology for SNP discovery. Twenty million short reads were generated and the proportion of repetitive sequences was reduced by more than 56%. A total of 6061 SNPs were identified, and 451 were mapped to the draft sequence of the barley genome with pairing reads. Eleven SNPs were validated using length polymorphic allele-specific PCR markers. 展开更多

Purpose: This paper aims to provide a systematic analysis of challenges and responses of the imminent open access-based environment so as to enable sound development of open access(OA) resource strategies.Design/methodology/approach: A systematic and evidence-based analysis is used to discover, identify, and contextualize the factors that relate or interact. A challenge metric for the overall context and additional frameworks or alternative lists is used for the detailed analysis.Findings: Research libraries are facing a reality conflict between the traditional library solution and the OA solution. New resource strategies are needed but have to be based on an open knowledge infrastructure and a systematic analysis of factors and alternatives. Support for OA publishing is becoming a major task and complicated capabilities involved call for libraries to play a central role. Hybrid collection development should be in place to take full advantages of the open world while ensuring reliable and trusted retrieval, reuse, and preservation.Research limitations: The research covers main developments in US and European countries mostly in scientific fields and for scholarly papers.Practical implications: There are already evidences for sound OA resource policies. With the imminent dominance of OA resources, research libraries should and can set up their OA resource strategies.Originality/value: The paper suggests a factor metric as an analysis framework, presents rationale lists and policies to support OA publishing, and proposes a hybrid collection strategy to plan for collection development, retrieval, and preservation. 展开更多

This study creates and combines the general maneuver libraries for fixed-wing aircraft to implement tactical maneuvers.First,the generalized maneuver libraries are established by analyzing the characteristics of tactical maneuvers required in battlefields.The 7th order polynomial is applied to both the creation of the maneuver libraries and the generation of the trajectories or flight paths for modal inputs.To track the desired trajectory,we design the Attitude Command Attitude Hold(ACAH)system and the Rate Command Rate Hold(RCRH)system using Model Following Controller(MFC).Moreover,the Line-of-Sight(LOS)guidance law is designed.In particular,the CONDUIT~?is employed to optimize the gains so that the control systems meet the aircraft Handling Qualities(HQ)criteria.Finally,flight simulations are performed for the longitudinal loop,immelmann-turn,and climb-slalom-descent maneuvers to verify that tactical aggressive maneuvers are realizable via the combination of maneuver libraries.This study can contribute to the development of flight techniques for aircraft tactical maneuvers and to the revision of air force operational manuals. 展开更多

Purpose: This study examines acknowledgments to libraries in the journal literature, as well as the efficacy of using Web of Science(WoS) to locate general acknowledgment text.Design/methodology/approach: This mixed-methods approach quantifies and characterizes acknowledgments to libraries in the journal literature. Using WoS's Funding Text field, the acknowledgments for six peer universities were identified and then characterized. The efficacy of using WoS to locate library acknowledgments was assessed by comparing the WoS Funding Text search results to the actual acknowledgment text found in the articles.Findings: Acknowledgments to libraries were found in articles at all six peer universities, though the absolute and relative numbers were quite low(< 0.5%). Most of the library acknowledgments were for resources(collections, funding, etc.), and many were concentrated in natural history(e.g. zoology). Examination of Texas A&M University zoology articles found that 91.7% of the funding information came from "acknowledgments" and not specifically a funding acknowledgment section. The WoS Funding Text search found 56% of the library acknowledgments compared to a search of the actual acknowledgment text in the articles.Research limitations: Limiting publications to journals, using a single truncated search term, and including only six research universities in the United States.Practical implications: This study examined library acknowledgments, but the same approach could be applied to searches of other keywords, institutions/organizations, individuals, etc. While not specifically designed to search general acknowledgments, WoS's Funding Text field can be used as an exploratory tool to search acknowledgments beyond funding. Originality/value: There are a few studies that have examined library acknowledgments in the scholarly literature, though to date none of those studies have examined the efficacy of using the WoS Funding Text field to locate those library acknowledgments within the journal literature. 展开更多

As far as China's enormous success in her economic reforms and development is concerned,Chinese rural migrant workers indeed have had their biggest share of contributions.Yet ironically in return,they have only received a disproportionate meager share of benefit rewards.These people represent a huge economically deprived group at the bottom of the social totem pole in China's metropolises.On the whole as a social group,their educational attainment is relatively low as compared to their average urban coworkers.As such being the case,their rights to access some of the cost-free cultural and educational enrichment programs in the society are limited and not always assured.Nevertheless and in general speaking,they manifest a strong and consistent desire to acquire all sorts of new and practical knowledge by means of accessing the resources and facilities of their local public libraries.It is suggested in this paper that public libraries are in a good position to give strong support to the central government's strategic planning for the development of a public culture service systema).In implementing such a government initiative with an unswerving purpose of advancing social justice and equality,public libraries should strife to provide as many as possible their library services at no cost to the public,especially to those socially deprived rural migrant workers. 展开更多

Biological risks of bioaerosols emitted from wastewater treatment processes have attracted wide attention in the recent years. However, the culture-based analysis method has been mostly adopted for detecting the bacterial community in bioaerosols, which may result in the underestimation of total microorganism concentration as not all microorganisms are cultivable. In this study, oligonucleotide fingerprinting of 16S rRNA genes was applied to reveal the composition and structure of the bacterial community in bioaerosols from an Orbal oxidation ditch in a Beijing wastewater treatment plant (WWTP). Bioaerosols were collected at different distances from the aerosol source, rotating brushes, and the sampling height was 1.5 m which is the common respiratory height of a human being. The bacterial communities of bioaerosols were diverse, and the lowest bacterial diversity was found at the sampling site just after the rotating brush rotating brush. A large proportion of bacteria in bioaerosols were affiliated with Proteobacteria and Bacteroidetes. Numerous bacteria present in the bioaerosols also emerged in water, indicating that the bacterial community in the bioaerosols was related to that of the aerosols' sources. The forced aeration of rotating brushes brought about observably distinct bacterial communities between sampling sites situated before and after the rotating brush. Isolation sources of closest relatives in bioaerosols clone libraries were associated with the aqueous environment in the WWTP. Common potential pathogens in bioaerosols as well as those not reported in previous research were also analyzed in this study. Measures should be adopted to reduce the emission of bioaerosols and prevent their exposure to workers. 展开更多
