(+)-Dimericbiscognienyne A: Total Synthesis and Mechanistic Investigations of the Key Heterodimerization
No full textThe
first total synthesis of (+)-dimericbiscognienyne A is described.
Key to the successful access to (+)-dimericbiscognienyne A was a biosynthetically
inspired Diels–Alder reaction between two differential epoxyquinoid
monomers and the subsequent intramolecular hemiacetal formation. The
selective formation of the natural product among other possible diastereomers
during the late-stage [4+2] cycloaddition reaction was investigated
by DFT calculations and experimental control studies
Gα12/13 signaling in metabolic diseases
No full textMetabolic diseases: Going after G proteins Understanding the activities of two members of a vital category of proteins called G proteins, which initiate metabolic changes when signaling molecules bind to cells, could lead to new therapies for many diseases. Researchers in South Korea and Japan, led by Sang Geon Kim at Seoul National University, review the significance of the Gα12 and Gα13 proteins in diseases characterised by significant changes in metabolism, including liver conditions and disorders of the cardiovascular and immune systems. Specific roles for the proteins have been identified by a variety of methods, including studying the effect of disabling the genes that code for them in mice. Recent insights suggest that drugs interfering with the activity of these Gα proteins might help treat many conditions in which the molecular signalling networks involving the proteins are disrupted
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
Inorganic nanoparticles with enzyme-mimetic activities for biomedical applications
Full text link© 2019 Elsevier B.V.Spurred by the recent advances in the chemical synthesis of nanomaterials, a group of inorganic nanoparticles with enzyme-mimetic activities has emerged as a new candidate to lead the future of nanomedicine. These so-called nanozymes have several advantages over their natural counterparts, such as more robust catalytic activities over wide ranges of pH and temperature, more economical production cost, and higher design flexibility through the integration and modification of various functional molecules and nanomaterials. To help readers understand this rapidly expanding field, we herein provide a short overview of the enzyme-mimetic activities of inorganic nanoparticles and their applications, with an emphasis on ceria and iron oxide nanoparticles, two of the most widely used nanozymes. Properties of other inorganic nanoparticle-based nanozymes are also briefly summarized. Finally, their current limitations and future outlook are discussed11sciescopu
Variations on the Author
Full text link“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
Full text linkWe 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
An efficient transmission of traffic and traveler information using digital multimedia broadcasting network
No full textThis paper introduces an efficient transmission of traffic and traveler information through digital multimedia broadcasting system, which is a multimedia and mobility empowered version of European digital audio broadcasting system. By introducing Korean characteristic traffic information into the transport protocol expert group messages, we could get highly efficient traffic and traveler information system that could be used in Korea as well as in European countries
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
