Effect of Types and Orders of Electromagnetic Field Finite Element Meshes on Power Communication Harmonic Parameters Calculation Results of Tubular Hydrogenerators

In generator design field,waveform total harmonic distortion(THD)and telephone harmonic factor(THF)are parameters commonly used to measure the impact of generator no-load voltage harmonics on the power communication quality.Tubular hydrogenerators are considered the optimal generator for exploiting low-head,high-flow hydro resources,and they have seen increasingly widespread application in China's power systems recent years.However,owing to the compact and constrained internal space of such generators,their internal magnetic-field harmonics are pronounced.Therefore,accurate calculation of their THD and THF is crucial during the analysis and design stages to ensure the quality of power communication.Especially in the electromagnetic field finite element modeling analysis of such generators,the type and order of the finite element meshes may have a significant impact on the THD and THF calculation results,which warrants in-depth research.To address this,this study takes a real 34 MW large tubular hydrogenerator as an example,and establishes its electromagnetic field finite element model under no-load conditions.Two types of meshes,five mesh densities,and two mesh orders are analyzed to reveal the effect of electromagnetic field finite element mesh types and orders on the calculation results of THD and THF for such generators.

Leadership,communication,and science:three pillars essential to public health emergency response and closing the gap in the HIV response among key populations

Globally,there have been multiple public health emergencies in recent decades.High rates of morbidity,occasionally mortality,and economic instability are usually associated with pandemics.One of the epidemics that has significantly increased morbidity and mortality worldwide is the human immunodeficiency virus(HIV)and acquired immune deficiency syndrome(AIDS)pandemic.HIV has a disproportionately negative impact on key populations.Strong leadership,effective communication,and sound science are necessary for public health emergency(PHE)responses to be successful.These three PHE response pllars are also essential for bridging the HIV response gap among key populations in the setting of restrictive laws.In this review,we explored the importance of these three pillars of successful PHEs responses,and how they are essential to closing the gap in the HIV response among key populations.Leaders must make decisions and instil a sense of authority in the populace during PHEs to foster trust and confidence.Leaders should base their choices on scientific evidence.Effective communication during PHEs should be proactive,polite,imaginative,innovative,and constructive.To address gaps in the HIV response among key populations,leaders must create a supportive environment for effective communication and scientific research,communication should be used to raise awareness of HIV and to dispel stigma and discrimination,while science should provide evidence of efficacy and effectiveness of interventions amongkey populations.

Functions of Rhetoric and Social Science Origins in Communication Study—Based on Boxing Plato’s Shadow:An Introduction to the Study of Human Communication

With the development of the rhetoric study from the origins in ancient Athens and The Rhetoric of Aristotle to the formation of modern Communication Study at the beginning of the twentieth century,the Rhetoric Study changed in dynamic and its concepts and theories merged and formed the foundations of Communication Study which focused on personal communication and speech rhetoric skills at that time.At the beginning of the twentieth century,although the Neo-Aristotelian rhetorical scholars from classic rhetoric approach created methodologies and enriched the content of Communication Study under the influence of humanistic study and social science study,but the Communication discipline was still in the embarrassing position.During World War I and World War II,most scholars with backgrounds of social science,history and anthropology carried out the studies of propaganda wars and the message disseminating,and explored the military powers and governments’access to the media and developed serial communication modes from the social science perspective,which laid the foundation for Communication discipline in the academic field.The author analyzed the Rhetoric and Social Science origins of Communication study in Boxing Plato’s Shadow:an Introduction to the Study of Human Communication,which is beneficial and helpful to understand the academic origins of Communication study and its cross-disciplined and embarrassing positions.

Effect size in papers published by the Journal of Forestry Research:A missing treasure?

P values based on standard hypothesis testing are commonly reported in articles published by the Journal of Forestry Research(JFR).However,effect sizes are barely used and reported,even if they are of direct relevance to the primary questions of many of the published studies.The incorporation of effect sizes in studies published by JFR should be encouraged and promoted.Inclusion of effect sizes as a requirement in the journal guidelines will facilitate a major change in the way data are tested and interpreted,with the ultimate goal to exempt researchers from the custom of drawing conclusions merely based upon a dichotomous statistical result(P value).Such a policy can also lead to more informed decisions of whether identified effects are of practical relevance to the forestry.

Robust Finite-time Synchronization of Non-identical Fractional-order Hyperchaotic Systems and Its Application in Secure Communication

This paper proposes a novel adaptive sliding mode control(SMC) method for synchronization of non-identical fractional-order(FO) chaotic and hyper-chaotic systems. Under the existence of system uncertainties and external disturbances,finite-time synchronization between two FO chaotic and hyperchaotic systems is achieved by introducing a novel adaptive sliding mode controller(ASMC). Here in this paper, a fractional sliding surface is proposed. A stability criterion for FO nonlinear dynamic systems is introduced. Sufficient conditions to guarantee stable synchronization are given in the sense of the Lyapunov stability theorem. To tackle the uncertainties and external disturbances, appropriate adaptation laws are introduced. Particle swarm optimization(PSO) is used for estimating the controller parameters. Finally, finite-time synchronization of the FO chaotic and hyper-chaotic systems is applied to secure communication.

Communication, Conviction, and Persuasion in The Origin of Species by Charles Darwin

Charles Darwin discovers that the theory of the species＇ creation by a miraculous being has reached a double impasse, due to the science ＂speech＂ evolution. There is an expositive impasse （it can＇t explain some facts any more） and a communication-comprehensive impasse （within its limits, some facts are not communicable or understandable）. In order to endorse his theory of evolutionism, Darwin develops an argumentative communicating science based on two axes： the facts and the axiomatics. His communicating science follows the next structure： （1） a relation with the starting thesis is established; （2） some evidence are promoted; （3） as the base of the evidence, a motivation is emphasized; （4） as a reason, an axiomatics is assigned to this base; and （5） finally, the facts and the quantifiers are explained by valid conclusions.

DEBRA: On the Unsupervised Learning of Concept Hierarchies from (Literary) Text

With this work, we introduce a novel method for the unsupervised learning of conceptual hierarchies, or concept maps as they are sometimes called, which is aimed specifically for use with literary texts, as such distinguishing itself from the majority of research literature on the topic which is primarily focused on building ontologies from a vast array of different types of data sources, both structured and unstructured, to support various forms of AI, in particular, the Semantic Web as envisioned by Tim Berners-Lee. We first elaborate on mutually informing disciplines of philosophy and computer science, or more specifically the relationship between metaphysics, epistemology, ontology, computing and AI, followed by a technically in-depth discussion of DEBRA, our dependency tree based concept hierarchy constructor, which as its name alludes to, constructs a conceptual map in the form of a directed graph which illustrates the concepts, their respective relations, and the implied ontological structure of the concepts as encoded in the text, decoded with standard Python NLP libraries such as spaCy and NLTK. With this work we hope to both augment the Knowledge Representation literature with opportunities for intellectual advancement in AI with more intuitive, less analytical, and well-known forms of knowledge representation from the cognitive science community, as well as open up new areas of research between Computer Science and the Humanities with respect to the application of the latest in NLP tools and techniques upon literature of cultural significance, shedding light on existing methods of computation with respect to documents in semantic space that effectively allows for, at the very least, the comparison and evolution of texts through time, using vector space math.

International scientific communications in the field of colorectal tumour markers

AIM To analyze scientometrically the dynamic science internationalization on colorectal tumour markers as reflected in five information portals and to outline the significant journals, scientists and institutions.METHODS A retrospective problem-oriented search was performed in Web of Science Core Collection(Wo S), MEDLINE, BIOSIS Citation Index(BIOSIS) and Scopus for 1986-2015 as well as in Dervent Innovations Index(Derwent) for 1995-2015. Several specific scientometric parameters of the publication output and citation activity were comparatively analyzed. The following scientometric parameters were analyzed:(1) annual dynamics of publications;(2) scientific institutions;(3) journals;(4) authors;(5) scientific forums;(6) patents-number of patents, names and countries of inventors, and(7) citations(number of citations to publications by single authors received in WoS, BIOSIS Citation Index and Scopus).RESULTS There is a trend towards increasing publication output on colorectal tumour markers worldwide along with high citation rates. Authors from 70 countries have published their research results in journals and conference proceedings in 21 languages. There is considerable country stratification similar to that in most systematic investigations. The information provided to end users and scientometricians varies between these data-bases in terms of most parameters due to different journal coverage, indexing systems and editorial policy. The lists of the so-called "core" journals and most productive authors in Wo S, BIOSIS, MEDLINE and Scopus along with the list of the most productive authors-inventors in Derwent present a particular interest to the beginners in the field, the institutional and national science managers and the journal editorial board members. The role of the purposeful assessment of scientific forums and patents is emphasized. CONCLUSION Our results along with this problem-oriented collection containing the researchers' names, addresses and publications could contribute to a more effective international collaboration of the coloproctologists from smaller countries and thus improve their visibility on the world information market.

Design of Practice Teaching of Public Order based on the Theory of Modern Instructional Design

At present, there are several problems such as randomness, blindness and experience in the teaching of public security science major, especially in practical teaching, thus colleges and universities cannot adapt to the requirements of talents training. In order to improve the practice teaching quality of public security practice, we should apply modern instructional design theory. Aiming at the problems existing in the practice teaching of public order, we design a practice teaching system for public security. In the process of practice teaching design of public order, we should pay attention to the starting point of the practice teaching, design of teaching objectives, design of practical teaching content, design of practical teaching mode and evaluation of the practice teaching of public security.

Efficient Quantum Secure Communication Protocol by Rearranging Particle Orders

We propose a quantum secure communication protocol by using three-particle GHZ states. In this protocol, we utilize the ideas of the rearranging orders and the sequence transmission. The sender of messages, Alice, first disturbs the particle orders in an initial sequence, and then sends the sequence of the disturbed orders to the receiver of messages, Bob. Under Alice＇s introduction, Bob rearranges the sequence back to the initial sequence. By making a GHZ state measurement on each of the three particles in turn, Bob can attain Alice＇s secret messages. In addition, we still calculate the efficiency of our three-particle GHZ protocol and generalize it to the case using multi-particle GHZ state.

Self Evaluation in Department of Communicable Diseases, Faculty of Medicine, Tehran University of Medical Sciences

Introduction: Self evaluation is a process that defines and collects required data to judge about decision making issues at educational system on whether the educational department is fit to educate students? The objective of this study was determining the quality of the structural elements of the department of Communicable Diseases & determining the strengths, weaknesses, opportunities and threats to improve the quality of activities in the department under research. Materials and Methods: The employed method was Mixed methods (qualitative & quantitative research), on the basis of 10 procedural steps and within 8 sections dealing with evaluated factors;such as 1) organizational and management structure 2) scientific board members 3) students 4) Manpower 5) Space of educational research and health care 6) Equipment 7) curriculum 8) satisfaction of graduates, which were studied using 61 criteria and 172 indicators. Five-point Likert Scale was used for the responses in the questionnaire (1 - 1.75 = undesirable, to 4.2 - 5 completely desirable). Finally the data were analyzed using descriptive statistics indices and the assessment software of the Educational Development Center of TUMS. The instruments used in this method included assessment software, interview, observation and self-prepared questionnaire which consisted of 7 questionnaires and 2 check lists. Finding: The results of the research showed that general average of 8 investigating sections was 56.9% as a rather desirable research work. Conclusions: Therefore, it was concluded that function of the educational management in that group was directly in line with evaluation process, but continuing the process of evaluation seems necessary.

Contribution of the Open Access Modality to the Impact of Hybrid Journals Controlling by Field and Time Effects

Purpose:Researchers are more likely to read and cite papers to which they have access than those that they cannot obtain.Thus,the objective of this work is to analyze the contribution of the Open Access(OA)modality to the impact of hybrid journals.Design/methodology/approach:The“research articles”in the year 2017 from 200 hybrid journals in four subject areas,and the citations received by such articles in the period 2017-2020 in the Scopus database,were analyzed.The hybrid OA papers were compared with the paywalled ones.The journals were randomly selected from those with share of OA papers higher than some minimal value.More than 60 thousand research articles were analyzed in the sample,of which 24%under the OA modality.Findings:We obtain at journal level that cites per article in both hybrid modalities(OA and paywalled)strongly correlate.However,there is no correlation between the OA prevalence and cites per article.There is OA citation advantage in 80%of hybrid journals.Moreover,the OA citation advantage is consistent across fields and held in time.We obtain an OA citation advantage of 50%in average,and higher than 37%in half of the hybrid journals.Finally,the OA citation advantage is higher in Humanities than in Science and Social Science.Research limitations:Some of the citation advantage is likely due to more access allows more people to read and hence cite articles they otherwise would not.However,causation is difficult to establish and there are many possible bias.Several factors can affect the observed differences in citation rates.Funder mandates can be one of them.Funders are likely to have OA requirement,and well-funded studies are more likely to receive more citations than poorly funded studies.Another discussed factor is the selection bias postulate,which suggests that authors choose only their most impactful studies to be open access.Practical implications:For hybrid journals,the open access modality is positive,in the sense that it provides a greater number of potential readers.This in turn translates into a greater number of citations and an improvement in the position of the journal in the rankings by impact factor.For researchers it is also positive because it increases the potential number of readers and citations received.Originality/value:Our study refines previous results by comparing documents more similar to each other.Although it does not examine the cause of the observed citation advantage,we find that it exists in a very large sample.
