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
A Chemistry and Material Perspective On Lithium Redox Flow Batteries Towards High-Density Electrical Energy Storage
Full text linkElectrical energy storage system such as secondary batteries is the principle power source for portable electronics, electric vehicles and stationary energy storage. As an emerging battery technology, Li-redox flow batteries inherit the advantageous features of modular design of conventional redox flow batteries and high voltage and energy efficiency of Li-ion batteries, showing great promise as efficient electrical energy storage system in transportation, commercial, and residential applications. The chemistry of lithium redox flow batteries with aqueous or non-aqueous electrolyte enables widened electrochemical potential window thus may provide much greater energy density and efficiency than conventional redox flow batteries based on proton chemistry. This Review summarizes the design rationale, fundamentals and characterization of Li-redox flow batteries from a chemistry and material perspective, with particular emphasis on the new chemistries and materials. The latest advances and associated challenges/opportunities are comprehensively discussed.Zhao, Yu, Yu Ding, Yutao Li, Lele Peng, Hye Ryung Byon, John B. Goodenough, and Guihua Yu.

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

Wan-Yu Chan Clarinet Recital Program Notes
No full textThis is the program notes for Wan-Yu Chan\ue2s Clarinet Solo Recital on May 13, 2021. It includes renowned clarinet repertoire from the nineteenth to the twentieth century, requiring both demanding technique, and rich musical expression.
The Stimmungen eines Faus Op. 11 f\uc3\ubcr Klarinette solo by Ilse Fromm-Michaels is a three-movement work with one of the \ue2expression\ue2 which leaves the audiences space of imagination. An important work in the twentieth century, the Concerto Pour clarinette et Orchestre de chambre by Eug\uc3\ua8ne Bozza has challenges to the players with it\ue2s high-level techniques and the unique composition style. Claude Debussy\ue2s Premi\uc3\ua9re Rhapsodie pour clarinette en si b\uc3\ua9mol was commissioned by the Conservatoire national sup\uc3\ua9rieur de musique et de danse de Paris as an examination piece for graduating Clarinet students. The changes of the tempo and the timbre highlight the piece. Alamiro Giampiere\ue2s Il Carnevale di Venezia Capriccio Variato is a theme and variations depicting the happy scenes during the Carnival of Venice. Arthur Honnegger\ue2s Sonatine pour clarinette en la & piano is a three-movement piece. A special technique \ue2Glissando\ue2 is used in his third movement showing a different musical style. This program notes present the biography of the composers, musical background, and interpretation of the above five pieces that I played in my solo recital

Chalcovietnamicus daiqini Yu & Hoang & Maddison & Zhang 2023
No full text<i>daiqini</i> -species group <p> This group can be distinguished from the <i>vietnamensis</i> -group by the lack of a large apical flag-like embolic apophysis (EA) on the back side of the embolus (Figs 60, 63–64, 66–67). The body is covered with dense khaki setae but never on the male face, palp, and tibia I, which are conspicuously darker than other body parts (Figs 4–5, 42–43, 70–72, 88–89). Females share three pairs of transverse setal bands on the posterior half of abdomen; the posterior pair is connected or very close to each other (Figs 11, 30, 48, 73, 90); female sternum has a cluster of long white setae on the posterior lateral edge of each side (but reduced in <i>C. marusiki</i> <b>sp. nov.</b> and <i>C. terbakar</i> <b>sp. nov.</b>; Figs 14, 32, 96).</p> <p> <b>Species included.</b> <i>Chalcovietnamicus daiqini</i> (Prószyński & Deeleman-Reinhold, 2012) <b>comb. nov.</b>, <i>C. logunovi</i> Yu, Maddison & Zhang, <b>sp. nov.</b>, <i>C. marusiki</i> Yu, Maddison & Zhang, <b>sp. nov.</b>, <i>C. terbakar</i> Yu, Maddison & Zhang, <b>sp. nov.</b>, <i>C. weihangi</i> Yu & Zhang, <b>sp. nov.</b>.</p>Published as part of <i>Yu, Kun, Hoang, Quang Duy, Maddison, Wayne P. & Zhang, Junxia, 2023, Review of Chalcovietnamicus Marusik, 1991, with description of four new species (Araneae, Salticidae, Euophryini), pp. 451-480 in Zootaxa 5336 (4)</i> on page 455, DOI: 10.11646/zootaxa.5336.4.1, <a href="http://zenodo.org/record/8282322">http://zenodo.org/record/8282322</a>
