Erythrodes triantherae C. L. Yeh et C. S. Leou (Orchidaceae), a New Species Bearing 1-3 Anthers
No full text本文記述產自臺灣?嶼之新種?科植物「三藥細筆?」之學名、形態特徵、產地、花期及標本等資?。本種之主要特徵為花之蕊柱具有1~3 枚花藥，即有1 或2 枚雄蕊常在蕊柱腹面出現，唇瓣較小，長4.5～5.5 mm，基部囊?而無長距。對於本種之花藥?目之變?情形及對於果實發育之初步觀察結果亦加以註記。並提供臺灣Erythrodes 屬之新檢?表。A new species of Erythrodes Blume (Orchidaceae), E. triantherae C. L. Yeh et C. S. Leou, from Lanyu of Taiwan is described and illustrated. It is characterized by the column which is adorned with 1-3 anthers, I.e. additional 2 or 1 stamens often present on the ventral side of column and in the lip which is much shorter (4.5-5.5 mm long) and only saccate at base, not long spurred. Results of a preliminary observation on the variation of anther number, and on the development of fruits have also been noted. We also provide a new key to the species of Erythrodes in Taiwan

Two-dimensional matrix algorithm using detrended fluctuation analysis to distinguish Burkitt and diffuse large B-cell lymphoma
Full text linkCopyright © 2012 Rong-Guan Yeh et al. This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited.A detrended fluctuation analysis (DFA) method is applied to image analysis. The 2-dimensional (2D) DFA algorithms is proposed
for recharacterizing images of lymph sections. Due to Burkitt lymphoma (BL) and diffuse large B-cell lymphoma (DLBCL), there
is a significant different 5-year survival rates after multiagent chemotherapy. Therefore, distinguishing the difference between BL
and DLBCL is very important. In this study, eighteen BL images were classified as group A, which have one to five cytogenetic
changes. Ten BL images were classified as group B, which have more than five cytogenetic changes. Both groups A and B BLs are
aggressive lymphomas, which grow very fast and require more intensive chemotherapy. Finally, ten DLBCL images were classified
as group C. The short-term correlation exponent α1 values of DFA of groups A, B, and C were 0.370 ± 0.033, 0.382 ± 0.022, and
0.435 ± 0.053, respectively. It was found that α1 value of BL image was significantly lower (P < 0.05) than DLBCL. However, there
is no difference between the groups A and B BLs. Hence, it can be concluded that α1 value based on DFA statistics concept can
clearly distinguish BL and DLBCL image.National Science Council (NSC) of Taiwan the Center for Dynamical Biomarkers and

Measurement of the ratio of prompt χ c to J / ψ production in pp collisions at √s = 7 TeV
Full text linkThe prompt production of charmonium χ c and J / ψ states is studied in proton-proton collisions at a centre-of-mass energy of √s = 7 TeV at the Large Hadron Collider. The χ c and J / ψ mesons are identified through their decays χ c → J / ψ γ and J / ψ → μ + μ - using 36 pb - 1 of data collected by the LHCb detector in 2010. The ratio of the prompt production cross-sections for χ c and J / ψ, σ (χ c → J / ψ γ) / σ (J / ψ), is determined as a function of the J / ψ transverse momentum in the range 2 < p T J / ψ < 15 GeV / c. The results are in excellent agreement with next-to-leading order non-relativistic expectations and show a significant discrepancy compared with the colour singlet model prediction at leading order, especially in the low p T J / ψ region
