Power-Electronics-Enabled Autonomous Power Systems
No full textThe eleven papers in this special section focus on power electronics-enabled autonomous systems. Power systems are going through a paradigm change from centralized generation to distributed generation and further onto smart grid. Millions of relatively small distributed energy resources (DER), including wind turbines, solar panels, electric vehicles and energy storage systems, and flexible loads are being integrated into power systems through power electronic converters. This imposes great challenges to the stability, scalability, reliability, security, and resiliency of future power systems. This section joins the forces of the communities of control/systems theory, power electronics, and power systems to address various emerging issues of power-electronics-enabled autonomous power systems, paving the way for large-scale deployment of DERs and flexible loads
Effect of Qing Chang oral liquid on the treatment of artificially infected chicken coccidiosis and the cellular immunity
No full textAbstract Background Qing Chang oral liquid (QOL) is a veterinary drug, which mainly composed of Artemisiae annuae herba, Dichroae radix, Agrimonia pilosa and Sanguisorbae radix. Objectives This study aims to explore the effect of Qing Chang Oral Liquid (QOL) on the treatment effect of artificially infected chicken coccidiosis and to the cellular immunity. Methods Healthy Roman chickens were randomly divided into five groups: blank group, model group, QOL high‐, medium‐ and low‐dose groups. All the groups were orally administered with 1 × 104 sporulated oocysts (except the blank group). After 5 days of oral administration, the high‐, medium‐ and low‐dose groups of QOL were added to the drinking water at 2.4, 1.8 and 1.2 ml/kg, respectively. The blank and model groups were fed normally, and this experiment lasted for 7 days. The clinical signs were observed, and the relative weight gain, survival rate, cecum lesion score and oocyst value were measured to evaluate the effect of QOL. Meanwhile, the peripheral blood T‐lymphocyte subsets and cecal IL‐2, IL‐17, IFN‐γ mRNA expression were detected by flow cytometry and fluorescent quantitative PCR. Results The chickens in the model group were in poor mental state, gathered together, had loose stools or bloody stools and had less food intake and less exercise. The chicken mental state improved, the food intake and drinking water increased, and the faeces are normal in the high‐, medium‐ and low‐dose groups, especially in the high‐dose group, the anti‐coccidial indexes were up to 173.08. No significant differences were observed (p > 0.05) in the peripheral blood CD3+, CD3+CD4+ between the experimental groups. Compared with the blank group, there were different degrees of increase in each dose drug group of the cecal IFN‐γ, IL‐2 and IL‐17 mRNA expression, but the high‐dose group was significantly reduced compared with the model group (p 0.05). Conclusions This study suggests that QOL has positive anti‐coccidial effect but has no obvious effect on the cellular immunity

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
