THz emission from intrinsic Josephson junctions in high-Tc superconductors for imaging applications
No full textIn 2007 [1], we have succeeded in observing strong, coherent, and continuous THz emission from a mesa of Bi 2 Sr 2 CaCu 2 O 8+s single crystal with a rectangular dimension of a few hundred micrometers in length, several tens of micrometers in width, and a few micrometers in thickness. Since then, great progress has been made both in understanding the fundamental mechanism of the radiation [2-6] and in practical applications [7-9] . References: [1] L. Ozyuzer, A. E. Koshelev, C.

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe 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
Importance of sympathetic activation for the expression of Na+-Ca2+ exchanger in end-stage failing human myocardium
No full textAims In end-stage heart failure, an alteration in the expression of the Na+-Ca2+ exchanger has been reported. Regulation of its expression is largely unknown. We sought to find out whether Na+-Ca2+ exchanger in human heart failure is regulated by sympathetic activation. In addition, since Na+-Ca2+-exchange is electrogenic, we conjectured whether increased expression of Na+-Ca2+ exchanger is associated with an increased incidence of cardiac arrhythmias. Methods and Results Twenty-three patients suffering from end-stage cardiac failure were examined in the hours preceding cardiac transplantation. Plasma levels of norepinephrine, epinephrine, atrial natriuretic peptide, renin activity, aldosterone, tumour necrosis factor (TNF)-alpha, and TNF-receptors were measured. All parameters were elevated relative to 21 healthy control subjects. As determined by immunoblots, protein levels of the Na+-Ca2+ exchanger were increased by 56% and protein levels of sarcoplasmic reticulum (SR) Ca2+-ATPase were decreased by 20% in left ventricles of the explanted failing hearts. A significant correlation between protein and neurohumoral levels was exclusively found for the Na+-Ca2+ exchanger with norepinephrine (r=0(.)64; P=0(.)01). Recent Holter ECGs revealed that patients with sustained or nonsustained ventricular tachycardia (more than three consecutive beats) had significantly higher Na+-Ca2+ exchanger protein and plasma norepinephrine levels than patients with a maximum of two consecutive beats (Na+-Ca2+ exchanger: 109 +/- 10 vs 83 +/- 7, n = 11 each, P<0(.)05; norepinephrine: 1359 +/- 159 vs 656 +/- 88 pg.ml(-1), n = 9 each, P<0(.)001). Conclusions Sympathetic activation may enhance the expression of Na+-Ca2+ exchanger in end-stage heart failure. The data support the hypothesis that increased Na+-Ca2+-exchange could favour malignant ventricular arrhythmias
Dispelling the Myths Behind First-author Citation Counts
No full textWe 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
The construction of Karen Karnak: The multi-author-function
No full textThis thesis is situated within the comparatively recent developments of Web 2.0 and the emergence of interactive WikiMedia, and explores the mode of authorship within a Read/Write culture compared to that of a Read/Only tradition. The hypothesis of this study is that the role of the audience has become merged with the author, and as such, represents new functions and attributes, distinct from a more conventional concept of authorship, in which the roles of audience and author are more separate. Read/Write and participatory culture, as defined by this study, is focused on collaboration, and includes the influences of D.I.Y. culture, Open-Source practices and the production of text by multiple authors. Multi-authorship presents a re-thinking of several concepts which support the notion of the individual author, since the focus of multi-authorship is not on attribution and ownership of a finished text, but on the continued malleability of a text. Modes of multi-authorship, demonstrated in the use of the pseudonyms Alan Smithee and Karen Eliot, represent declarative authors whose names signify multiple origins, whilst concurrently indicating a distinct body of work. The function of these names form an important context to this study, since primary research involves the construction of an experimental mode of multi-authorship utilising WikiMedia technology and the interaction of thirty nine participants, who are invited to create a body of work under the collective pseudonym Karen Karnak. The data generated by this experiment is analysed using aspects of Michel Foucault's author-function to identify and determine power structures inherent in the WikiMedia context. The interplay of power structures, including concepts such as identity, ownership and the body of work, affect the resulting mode of authorship and contribute to the construction of Karen Karnak, suggesting further areas of research into the emerging multi-author
Contribution of Information and Communication Technology (ICT) in Country’S H-Index
No full textThe aim of this study is to examine the effect of Information and Communication Technology (ICT) development on country’s scientific ranking as measured by H-index. Moreover, this study applies ICT development sub-indices including ICT Use, ICT Access and ICT skill to find the distinct effect of these sub-indices on country’s H-index. To this purpose, required data for the panel of 14 Middle East countries over the period 1995 to 2009 is collected. Findings of the current study show that ICT development increases the H-index of the sample countries. The results also indicate that ICT Use and ICT Skill sub-indices positively contribute to higher H-index but the effect of ICT access on country’s H-index is not clear
Fully Turbulent Mean Velocity Profile for Purely Viscous non-Newtonian Fluids
No full textThe characteristic near wall behavior of turbulent flow of purely-viscous non-Newtonian fluids is discussed for both power-law (P.-L.) and Herschel-Bulkley (H.-B.) rheological models. A proper scaling is presented for H.-B. fluids to establish an analogy with power-law fluids with same flow index. To provide reference data for turbulent flow of non-Newtonian fluids, DNS simulations of power-law fluids are conducted in a rectangular channel for a large range of power-law indices ( = 0.5, 0.69, 0.75, 0.9, 1, 1.2). The DNS data show that the mean velocity profile in the viscous and logarithmic layers follow expressions of the form and respectively, where shows a logarithmic dependency on the flow index.Comparison with some experimental data shows the above formulation to be valid for Reynolds numbers (based on shear velocity) as high as 1000
