No full textSinojassus aspinus Dai, Zhang and Zhang sp. nov. Figs 2, 5, 8, 28– 35. Male 7.5 mm long, 2.3 mm wide across eyes and 2.9 mm wide across hind margin of pronotum. Female 7.5 mm long, 2.3 mm wide across eyes and 2.9 mm wide across hind margin of pronotum. Ratio of width of head including eyes to hind margin of pronotum 0.79. Pale greenish brown with brown spots. Forewings and legs brown. Male genitalia: Caudal margin of pygofer convexly rounded, without macrosetae. Subgenital plate of uniform width, upturned, and with rounded apex, several microsetae on lateral margin. Style narrow and long, apophysis curved dorsally almost at right angle, robust with rounded apex. Aedeagus with well developed bifid dorsal apodeme, preatrium absent, aedeagal shaft slightly widened apically in lateral view, apex in caudal view broadened with apical median notch. Female genitalia: Seventh sternite 1.5 times as long as sixth, hind margin with slight V-shaped concavity. Material examined. Holotype 3, China, Sichuan Prov., Xikang, Gonggashan, 10–12 Sep. 1939, Zhou Yao, Zheng Fengling and Du Tianhe. Paratype: 1 Ƥ, data as holotype (All in NWAFU). FIGURES 1–13. Figs. 1, 4, 7, 11– 13, Sinojassus loberus; Figs. 2, 5, 8, Sinojassus aspinus; Figs. 3, 6, 9, Sinojassus compressus. 1–3, Habitus, dorsal view; 4–6, Habitus, lateral view; 7–9, face; 10, Female first gonapophysis; 11, Magnified view of apex of first gonapophysis; 12, female second gonapophysis; 13, Magnified view of apex of female second gonapophysis. Remarks. This species resembles Sinojassus loberus externally but can be distinguished from the latter by: 1) lack of dark patches on the forewings and legs brown; 2) subgenital plate not triangular; 3) male pygofer without a ventral lobe and without macrosetae; 4) aedeagus widened near apex with a median notch; and 5) style with more robust apophysis. Etymology. The name of the species refers to the absence of macrosetae on the male pygofer.Published as part of Dai, Wu, Zhang, Xinmin & Zhang, Yalin, 2010, A new Oriental genus of Iassini leafhoppers (Hemiptera: Cicadellidae: Iassinae) with description of four new species, pp. 15-26 in Zootaxa 2641 on pages 18-21, DOI: 10.5281/zenodo.19859
Fast spectroscopic imaging using extreme ultraviolet interferometry
No full textExtreme ultraviolet pulses as generated by high harmonic generation (HHG) are
a powerful tool for both time-resolved spectroscopy and coherent diffractive
imaging. However, the integration of spectroscopy and microscopy to harness the
unique broadband spectra provided by HHG is hardly explored due to the
challenge to decouple spectroscopic and microscopic information. Here, we
present an interferometric approach to this problem that combines Fourier
transform spectroscopy (FTS) with Fourier transform holography (FTH). This is
made possible by the generation of phase-locked pulses using a pair of HHG
sources. Crucially, in our geometry the number of interferometric measurements
required is at most equal to the number of high harmonics in the illumination,
and can be further reduced by incorporating prior knowledge about the structure
of the FTH sample. Compared to conventional FTS, this approach achieves over an
order of magnitude increase in acquisition speed for full spectro-microscopic
data, and furthermore allows diffraction-limited computational imaging

Solution-processed bulk heterojunction organic solar cells based on an oligothiophene derivative
No full textOrganic bulk heterojunction (BHJ) solar cells based on a dicyanovinyl-substituted oligothiophene as a donor and [6,6]-phenyl C61 butyric acid methyl ester (PCBM) as an acceptor were fabricated and characterized. The oligothiophene derivative can absorb long wavelength photons of the solar radiation, which makes the solar cells with an optimized weight ratio of 1:1.4 have a decent short-circuit current density (12.4 mA/cm(2)) and open-circuit voltage (0.88 V) under AM 1.5G illumination with an intensity of 100 mW/cm(2). A power conversion efficiency (PCE) of 3.7% is achieved, which is among the best PCEs of solution processed small molecule BHJ solar cells.Original Publication:Bin Yin, Liying Yang, Yongsheng Liu, Yongsheng Chen, Qingjin Qi, Fengling Zhang and Shougen Yin, Solution-processed bulk heterojunction organic solar cells based on an oligothiophene derivative, 2010, Applied Physics Letters, (97), 2, 023303.http://dx.doi.org/10.1063/1.3460911Copyright: American Institute of Physicshttp://www.aip.org

An enhanced author name dataset for PubMed/MEDLINE
No full text<p>The incompleteness of author names is a well-known issue in the MEDLINE database. It was since 2002, the full author name has been systematically indexed in MEDLINE. Although many full author names have been added to MEDLINE, we still found a significant number of abbreviated names in papers published after 2002.</p>
<p>Here we built an enhanced author name dataset for MEDLINE, called EAN, achieved by linking the whole PubMed to other large literature databases and conducting a large-scale name comparison and restoration with obtained multi-sources author names. Our evaluation shows that more than 90% of author names in EAN are complete as compared to the ratio of ~60% in MEDLINE.</p>

Professor Zhang Weihua's Clinical Experience in the Application of Yongquan Acupoint
No full textSummarizing Professor Zhang Weihua's understanding of the bidirectional regulation function of Yongquan Point and his clinical application experience, the author believes that Yongquan is a meeting place of Yin and Yang qi, and both Yin and Yang qi are rooted here, which can be used to balance Yin and Yang, and proposes that Yongquan is the key point of bidirectional regulation, which has the functions of bidirectional regulation, bidirectional lifting, bidirectional replenishing. At the same time, Professor Zhang believes that Yongquan point should be combined with the corresponding stimulation method in the treatment of different diseases, which provides a new idea for the clinical treatment of some difficult diseases
