Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Utilization of Artocarpus heterophylla Lamk. As UV Protector In mice exposed to UV-B
Get PDFIn daily life, Artocarpus heterophylla Lamk., the leaves are rarely used even just as animal feed. In the bark of Artocarpus heterophylla Lamk there are new flavonoid compounds namely morusin, artokarpin, artonin E, cycloartobilosantone, and artonol B. This research is an experimental design with randomized posttest only with control group design. A total of 21 mice were divided into 3 groups, each consisting of 7 mice, group 1: negative control given oral placebo and exposed to UV-B rays, group 2:giving Vitamin C cream 4% mg and exposed to UV-B rays, group 3: giving cream of Artocarpus heterophylla Lamk leaf extract 4% and exposed to UV-B rays. The total of UV radiation dose of 600 mJ / cm² for 3 weeks, then performed a biopsy for examination of the amount of dermis collagen. The average number of collagen in the three groups after treatment was given significantly different (p <0.05). Mean and Significant level of collagen density of group 1 : 51,42 ± 5,16; group P2 ± 91,18 ± 1,13; and P3 group: 88,77 ± 1,10. Conclusion : Cream of 4% Artocarpus heterophylla Lamk leaf extract can increase the amount of collagen density in mice exposed to UV-B rays
Measurement of the ratio of branching fractions B(B0→K∗0γ )/B(B0s→φγ ) and the directCP asymmetry inB 0→K∗0γ
Get PDFThe 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

Measurement of b-hadron masses
Get PDFMeasurements of b-hadron masses are performed with the exclusive decay modes B +→J/ψK +, B 0→J/ψK +, B0→J/ψKS0, Bs0→J/ψφ and Λb0→J/ψΛ using an integrated luminosity of 35pb -1 collected in pp collisions at a centre-of-mass energy of 7 TeV by the LHCb experiment.
