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

An analytic Yeh-Feynman-Fourier transform and convolution
No full textLet C\sb0\lbrack0,T\rbrack denote Wiener space. Brue introduced the idea of an L\sp1 analytic Feynman-Fourier transform of functionals on C\sb0\lbrack0,T\rbrack in 1971. Since then many people including Cameron, Johnson, Martin, Skoug and Storvick have extended this theory to L\sp{p} with 1 p 2 for many classes of functionals. Recently, there has also been interest in convolution of functionals on C\sb0\lbrack0,T\rbrack and its relationship to the analytic Feynman-Fourier Transform. Let Q = (0,b) and let C\sb2\lbrack Q\rbrack = \{x(s,t): x is real valued, continuous on Q and x(0,t) = x(s,0) = 0. Yeh developed a measure m on this space and hence we will call C\sb2\lbrack Q\rbrack together with m, Yeh-Wiener Space. In this dissertation we will create an L\sp{p} analytic Yeh-Feynman-Fourier transform of functionals on C\sb2\lbrack Q\rbrack. Also a convolution product will be introduced for functionals on C\sb2\lbrack Q\rbrack. We then show that this transform and convolution product have many of the same properties as the Fourier transform of functions on \Re\sp{n}. That is, we show the inverse transform of the transform of a functional is the original functional. Also we show that the transform of the convolution equals the product of the transforms. Finally, we consider an identity similar to the Plancherel identity. In chapter one we give the basic definitions of Yeh-Wiener space, the analytic Yeh-Feynman-Fourier transform and convolution product. We then consider three classes of functionals on C\sb2\lbrack Q\rbrack. In chapter two we consider functionals of the form F(x) = f(x(s\sb1,t\sb1),x(s\sb1,t\sb2),\...,x(s\sb{m},t\sb{n})). Next, in chapter three we consider functionals of the form F(x) = \int\sb{Q}\int f(s,t,x(s,t)ds dt. Finally we consider functionals of the form F(x) = f(\int\int\sb{Q}\alpha\sb1dx(s,t),\...,\int \int \alpha\sb{n}dx(s,t)) in chapter four. We then close our work by giving a number of specific examples of the transform and its properties in chapter five
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

No full textReticulaphis septica Yeh & Hsu sp. nov. (Figs. 14, 15) Apterous adult female. A small species, body ovate, black with purplish-blue burnish, marginal setae short and stout, with fan-shaped apices, body margin without waxy powder. Body 0.47–0.53 mm long, about 1.33 (1.27–1.41) times as long as wide, widest part at position corresponding to front legs, 2 shrunken furrows from prosomal margin to submargin at positions corresponding to front and middle legs. Antennae much shorter than space between them, L-shaped bend without segmentation, long arm about 25–37.5 μm with 1 minute rhinaria and 1 terminal seta near apex. Eyes submarginal, with 2 facets (some individuals with 3 facets). Prosoma distinctly reticulated with pale thin lines, dorsum with 3 deep transverse ridges on median area and several rounded areas surrounding it; 5 pairs of minute setae on central axis of prosoma, 1 st pair between eyes; prosoma with 10 pairs of marginal setae, all marginal setae short and stout, almost as long as long arm of antennae, with fan-shaped or serrated apices. Legs short, hind legs somewhat exposed; front and middle tibiae shorter than femora, hind tibiae equal to or shorter than femora; tarsi narrower than tibia, longer than wide; 1 long fine capitate seta on dorsal front tarsi, 2 such setae on middle and hind tarsi. Abdominal tergites II–VII about 140–157.5 μm wide and 57.5–67.5 μm long, also reticulated, without siphunculi and with 6 pairs minute setae along converging sides of tergites, only base tubercles visible. Abdominal tergite VIII an equilateral triangle, about 75–85 μm wide and 30–40 μm long, with 2 blunt, stout apical setae, nearly as long as marginal setae. Cauda knobbed, constricted basally. Subanal plate deeply bilobed, each lobe with 4–6 setae. Material examined. Holotype, Taiwan: Dashe Township, Kaohsiung Co., on Ficus septica, 9 -iv- 2006, H.T. Yeh (# 476). Paratypes, Taiwan: Luodong Township, Ilan Co., 28 -iii-2006, 22 apterous adults from F. septica (on 2 microscope slides) (Y.F. Chen # 469); Baihe Township, Tainan Co., 8 -iv-2007, 12 apterous adults from F. septica (C.C. Ko # 596); Da-an District, Taipei City, 21 -iv-2007, 14 apterous adults from F. septica (T.C. Hsu # 600); Dashe Township, Kaohsiung Co., 27 -v-2007, 48 apterous adults from F. septica (on 7 microscope slides) (H.T. Yeh # 608) (ANIC, BMNH, CDFA, NMNS, TARIIC, USNM). Etymology. The specific name ‘ septica ’ is derived from the associated host plant, F. s e p t i c a. Remarks. This species can be found in suburbs or hills, and feeds year round on new to mature leaves. The population density can be very high on mature leaves, and often causes serious sooty molds. This species differs from R. mirabilis in the pair of tiny setae between the eyes on the dorsal prosoma, and the comparatively stout marginal setae with distinctly fan-shaped apices of the prosoma; and differs from R. asymmetrica by the ovate body shape, and the pleural regions of prosoma not being expanded.Published as part of Yeh, Hsin-Ting, Ko, Chiun-Cheng & Hsu, Tung-Ching, 2008, Review of the East-Asian genus Reticulaphis (Aphididae: Hormaphidinae), with two new species, pp. 34-48 in Zootaxa 1782 on pages 45-46, DOI: 10.5281/zenodo.27431
