Astragalus wui M. Idrees & Z. Y. Zhang 2021, nom. nov.
No full textAstragalus wui M. Idrees & Z.Y. Zhang, nom. nov. Replaced name:— Astragalus sylvaticus Y.H. Wu (2015: 718), nom. illeg., non A. sylvaticus (Pall.) Willd. (1802: 1300). Type:— CHINA. Xinjiang: Yecheng Country, Sukepiya, in border forest, alt. 3000 m, 15 Aug. 1987, Exped. Qinghai-Tibet Wu Yuhu 1067 (holotype: QTPMB, not seen). Etymology:—The specific epithet honours Prof. Dr. Wu Yuhu (Northwest Institute of Plateau Biology, Chinese Academy of Science, Xining, China), author of the replaced name, who first described this new species.Published as part of Idrees, Muhammad & Zhang, Zhiyong, 2021, Astragalus wui, a new replacement name for A. sylvaticus Y.

Macrosiphoniella sensorinuda Zhang 1992
No full textMacrosiphoniella sensorinuda Zhang 1992 = Macrosiphoniella lijiangensis Zhang 1992 M. sensorinuda is described in the same paper and from the same host (Artemisia vulgaris L.) as M. lijiangensis, and is distinguished as having shorter siphunculi and cauda. We have examined paratypes of both species, and conclude that there must have been an error in measuring these characters in the description of M. sensorinuda, and that it is a synonym of M. lijiangensis, which has page priority.Published as part of Victor, Eastop, F. & Blackman, Roger L., 2005, Some new synonyms in Aphididae (Hemiptera: Sternorrhyncha), pp. 1-36 in Zootaxa 1089 on page 13, DOI: 10.5281/zenodo.27334

Inter-Carrier Interference Analysis of OFDM Systems Communicating Over Rapidly-Fading Nakagami-m Channels
No full textIn this contribution, the Bit Error Rate (BER) performance of OFDM systems using coherent demodulation over time-variant flat Nakagami-m fading channels is analyzed. In a rapidly fading environment the orthogonality of the OFDM subcarrier signals may be destroyed and this phenomenon potentially results in InterCarrier Interference (ICI). The novel contribution of the paper is that the desired signal is shown to be accurately modelled as a function of the sum of two correlated Nakagamim variables, provided that the Doppler shift is moderate. It is also shown that the ICI can be modelled as a function of the difference of two correlated Nakagami-m variables. Finally, it is demonstrated that the assumption of having a near-Gaussian ICI distribution is inaccurate, hence leading to an inaccurate BER estimate, which is associated with a pessimistically high BER-floor

Polystichum hubeiense (Dryopteridaceae), a new fern species from Hubei, China
No full textZhang, L., Zhu, Z. M., Gao, X. F. & Zhang, L. B. 2013: Polystichum hubeiense (Dryopteridaceae), a new fern species from Hubei, China. - Ann. Sot. Fennici 50: 107-110. A new fern species, Polystichum hubeiense Liang Zhang & Li Bing Zhang (Dryopteridaceae), is described and illustrated from limestone cliffs in western Hubei Province, China. Polystichum hubeiense is most similar to P. lanceolatum in having relatively small leaves and pinnae and similar pairs of pinnae per lamina. The new species is distinguished by having overlapping and papery pinnae that are dull adaxially and repand on the margin, while P. lanceolatum has contiguous and leathery pinnae that are lustrous adaxially and dentate and with hard spines on the margin
