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

Measurement of the ratio of branching fractions B(B0→K∗0γ )/B(B0s→φγ ) and the directCP asymmetry inB 0→K∗0γ
No full textThe ratio of branching fractions of the radiative B decays B0→K⁎0γ and B0s→ϕγ has been measured using an integrated luminosity of 1.0 fb−1 of pp collision data collected by the LHCb experiment at a centre-of-mass energy of s√=7TeV. The value obtained is
B(B0→K⁎0γ)B(B0s→ϕγ)=1.23±0.06(stat.)±0.04(syst.)±0.10(fs/fd),
where the first uncertainty is statistical, the second is the experimental systematic uncertainty and the third is associated with the ratio of fragmentation fractions fs/fd. Using the world average value for B(B0→K⁎0γ), the branching fraction B(B0s→ϕγ) is measured to be (3.5±0.4)×10−5.
The direct CP asymmetry in B0→K⁎0γ decays has also been measured with the same data and found to be
ACP(B0→K⁎0γ)=(0.8±1.7(stat.)±0.9(syst.))%.
Both measurements are the most precise to date and are in agreement with the previous experimental results and theoretical expectations
A Study on The Korean Folk Music &apos;BONG-JANG-CHUI&apos; : Focusing of The Hae-geum Player, Kim Ducjin&apos;s Melody
No full text봉장추(鳳將雛), 봉작취(鳳雀吹), 봉황곡(鳳凰曲), 봉장취 굿거리 또는 새타령 등 다양한 이름으로 불리웠던 봉장취는 조선후기부터 일제 강점기 전후까지 많이 연주되었으나 지금은 전승이 끊긴 상태이다. 산조의 전신이라고도 알려져 있는 봉장취는 연주 악기, 연주 형태, 음악 내용에 따라 다양한 유형으로 발전되었다. 본고는 1930년대 초기해금산조의 창시자이며, 경기지방을 중심으로 활동하였던 김덕진의 자취와 그가 남긴 SP유성기 음반 중 콜롬비아판 ‘고악봉장취’와 ‘해금봉장취’를 채보하고 분석하여 보았다.
김덕진(金德鎭) 혹은 김덕준(金德俊)이라는 이름으로 활동한 그는 日本 Victor社와 Columbia레코드사 등에서 17여개의 음원을 남겼고, 경성방송국에서도 1935년부터 1943년까지 약 8년 동안 방용현, 이동백, 이화중선, 한성준, 지용구, 정해시, 지영희, 이소향 등과 함께 활동을 하였다.
본고는 김덕진의 ‘고악봉장취’와 ‘해금봉장취’를 채보하고 장단, 구성음, 선율의 내드름과 종지형으로 나누어 연구한 결과 다음과 같은 결과를 얻었다. ‘고악봉장취’는 중모리 장단으로 되어 있고, 새소리 선율형이 없고 모두 봉장취 선율형으로 되어 있다. 또한 조의 변화가 많은데 정리하자면, Eb 본청 - Bb 청 (Eb의 떠는 음) - eb본청 (처음 시작의 옥타브 관계) - Ab청 (eb과 완전5도 엇청)로 조가 변화한다. 관계조로의 청의 이동, 해금의 특성상 포지션을 옮기지 않고 한두 가지의 음정만 바꾸어 조가 변한 느낌을 주는 변조 청은 한범수류 해금산조 진양에서도 보여 지는 전조 방법 중 하나이며, 한 가지 청으로만 연주하는 시나위와는 구별된다. 또 청을 옮기기 전이나 후에 관련 엇청을 자주 출현시켜 음악적 통일성을 이루는 부분은 김덕진의 음악성을 짐작케 한다.
‘해금봉장취’ 는 늦은 자진모리장단으로 되어 있는데 총 8단락으로 이루어지며, 전조는 하지 않고 eb본청의 남도 계면조 음계를 갖고 있다. 그러나 새소리를 흉내 내는 새소리 선율형과 봉장취 선율형이 뚜렷하게 나타나 전형적인 봉장취의 모습을 갖추고 있다.
김덕진의 봉장취를 채보 &amp;#8228; 분석하면서, 현행 연주되고 있는 해금 산조와 유사한 점을 찾을 수 있었는데 그것들을 정리하자면 다음과 같다. 산조에서 사용되는 중모리, 중중모리, 자진모리장단을 사용하였다. 명인들의 증언으로 보아 용어적인 면이나 음악적인 면으로 초기산조와 봉장취는 음악적으로 서로 경계가 모호하였고, 산조의 창시자들도 이 두 장르를 뚜렷하게 구분하려는 노력은 별로 없었던 것으로 보인다. 또 봉장취의 분석과정에서 김덕진의 봉장취는 산조처럼 완벽한 기승전결의 구조는 갖고 있지 않지만 나름의 선율진행을 구성하고 있다. 김덕진의 봉장취는 구성음과 선율구조에 따라 단락을 나눌 수 있으며, 짜여진 내드름과 종지형이 존재한다. 산조의 가장 큰 특징이 긴장과 이완의 형식미라고 볼 수 있는데, 봉장취도 일련의 형식미를 갖고 있었다.;Bong-jang-chui, as known as Bong-jang-chu, Bong-jak-chui, Bong-hwang-gok, Bong-jang-chui-gutgury, or Sae-taryeong(bird ballad), used to be very popular from late Chosun dynasty to Japanese colonial period. It is known as a predecessor of San-jo and had been developed in various forms in accordance with its musical instrument, style of performance, and contents. This thesis is about a musician Kim Dukjin, the initiator of 1930&apos;s early Hae-geum San-jo who had performed mostly in Kyeung-gi provence, and analysis of his music Go-ak(old music) Bong-jang-chui and Hea-geum Bong-jang-chui from his SP gramophone album, Colombia&apos;s edition.
Kim Dukjin, or Kim Dukjun, had released 19 sound sources from many Japanese recording companies such as Victor, Colombia, and so on. He also performed in Kyeongseong broadcasting station for about 8 years, from 1935 until 1943, with Bang Younghyeon, Lee Dongbeak, Lee Hwajoongsun, Han Sungjoon, Ji Yonggu, Jung Heasi, Ji Younghee, and Lee Sohyang.
The result of the analysis of his Go-ak Bong-jang-chui and Hae-geum Bong-jang-chui by its rhythm, note, and melody&apos;s beginging motive and cadance form is as follows. Go-ak Bong-jang-chui has Joong-mori rhythm and Bong-jang-chui melody and no Sae-sori melody. Also, it has variation of key which consists of Eb original - Bb original(Eb&apos;s dominant key) - eb original(an octave relationship with the first part) - Ab original (subdominant key with eb). Movement of tonic to a relative key, a change of tonic by changing couple of intervals not a whole position which is only possible for Hae-geum, is one of the transitions also shown in Han Bumsu&apos;s Hea-geum San-jo Jin-yang and is distinct with Si-na-wi, which is played with only one tonic. In addition, creating the unity by inserting the dominant note frequently before changing the note shows Kim Dukjin&apos;s musicianship.
Hea-geum Bong-jang-chui is made up of eight passages and has late Ja-jin-mori rhythm, no transitions, and eb origianal Nam-do interface-key scale(kyemean-key scale). However, as a typical Bong-jang-chui, it has Sae-sori melody which imitates the bird&apos;s note and Bong-jang-chui melody .
The analysis made it possible to find out, the similarity of Kim Dukjin&apos;s Bong-jang-chui and San-jo of nowadays. It had Joong-mori, Joongjoon-mori, and Jajin-mori rhythm as San-jo. According to masters testimony, early San-jo and Bong-jang-chui was indistinguishable in a musical or a terminological aspects, and the initiators of San-jo didn&apos;t bother to distinguish these two genres either. Besides, Kim Dukjin&apos;s Bong-jang-chui doesn&apos;t have the as perfect structure of introduction, development, turn and conclusion as San-jo but has it&apos;s own structure of melody. Kim Dukjin&apos;s Bong-jang-chui can be divided into passages in accordance with the notes well-organized beginning motive and cadence form. It has a beauty of form which is similar to San-jo&apos;s typical form of tension and relaxation.Ⅰ. 서론 = 1

Evidence for the decay B0→J/ψω and measurement of the relative branching fractions of meson decays to J/ψη and J/ψη′
No full textFirst evidence of the B 0 → J / ψ ω decay is found and the B s 0 → J / ψ η and B s 0 → J / ψ η ′ decays are studied using a dataset corresponding to an integrated luminosity of 1.0 fb -1 collected by the LHCb experiment in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV. The branching fractions of these decays are measured relative to that of the B 0 → J / ψ ρ 0 decay:frac(B (B 0 → J / ψ ω), B (B 0 → J / ψ ρ 0)) = 0.89 ± 0.19 (stat) - 0.13 + 0.07 (syst),frac(B (B s 0 → J / ψ η), B (B 0 → J / ψ ρ 0)) = 14.0 ± 1.2 (stat) - 1.5 + 1.1 (syst) - 1.0 + 1.1 (frac(f d, f s)),frac(B (B s 0 → J / ψ η ′), B (B 0 → J / ψ ρ 0)) = 12.7 ± 1.1 (stat) - 1.3 + 0.5 (syst) - 0.9 + 1.0 (frac(f d, f s)), where the last uncertainty is due to the knowledge of f d / f s, the ratio of b-quark hadronization factors that accounts for the different production rate of B 0 and B s 0 mesons. The ratio of the branching fractions of B s 0 → J / ψ η ′ and B s 0 → J / ψ η decays is measured to befrac(B (B s 0 → J / ψ η ′), B (B s 0 → J / ψ η)) = 0.90 ± 0.09 (stat) - 0.02 + 0.06 (syst)

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
Measurement of the differential inclusive B+ hadron cross sections in pp collisions at root s=13TeV
No full textThe differential cross sections for inclusive production of B+ hadrons are measured as a function of the B+ transverse momentum p(T)(B) and rapidity y(B) in pp collisions at a centre-of-mass energy of 13 TeV, using data collected by the CMS experiment that correspond to an integrated luminosity of 48.1 pb(-1). The measurement uses the exclusive decay channel B+ -> J/psi K+, with J/psi mesons that decay to a pair of muons. The results show a reasonable agreement with theoretical calculations within the uncertainties. (C) 2017 The Author(s). Published by Elsevier B.V
