Extending Human Perception of Electromagnetic Radiation to the UV Region through Biologically Inspired Photochromic Fuzzy Logic (BIPFUL) Systems.
No full textPhotochromic Fuzzy Logic Systems have been designed that extend human visual perception into the UV region. The systems are founded on a detailed knowledge of the activation wavelengths and quantum yields of a series of thermally reversible photochromic compounds. By appropriate matching of the photochromic behaviour unique colour signatures are generated in response differing UV activation frequencies

However, <i>L. formosus</i> differs from <i>L. fragilis</i> by the following characters: (1) head and pronotum bears very weak shagreen (in contrast, a distinct shagreen consisting of micropunctures is developed on the head and pronotum of <i>L. fragilis</i>); (2) primary and secondary rows of elytra are rather similar to each other in size of punctures (they differ in size of punctures in <i>L. fragilis</i>); (3) apex of the median lobe is rounded apically (acute in <i>L. fragilis</i>); and (4) parameres partly sclerotized and hence regularly expanded at apex (apex of parameres membranous and hence irregularly expanded in <i>L. fragilis</i>). The aedeagus of a Chinese specimen of <i>L. formosus</i> is illustrated in Fig. 19.</p> <p> <b> <i>Laccobius</i> (<i>Microlaccobius</i>) <i>hammondi</i></b> Gentili, 1984 (Figs. 20–25)</p> <p> <b>Material examined.

It may be separated from the latter by the aedeagus, having the median lobe more dilated at the apical third than <i>L. oscillans</i> (compare Figs. 25 and 26). Another distinctive character seems to be the pronotal surface, which is strongly shagreened in <i>L. oscillans</i>.</p> <p> The examined male specimen from Beijing has the aedeagus identical to the specimens from Shaanxi and Jiangxi. Reexamination of the specimens from the Jilin province published as <i>L. oscillans</i> by Gentili (1995) shows that the specimens are actually more similar to <i>L. hammondi</i> than to <i>L. oscillans</i> in the above characters. These data suggest that the previous records of <i>L. oscillans</i> from Beijing, northern China and possibly even Russian Far East may refer to <i>L. hammondi.</i> A revision of the specimens from continental Asia as well as from southern Japan is necessary to understand the real distribution of both <i>L. oscillans</i> and <i>L. hammondi</i>.</p> <p> The aedeagus of <i>Laccobius</i> (<i>M.</i>) <i>yonanguniensis</i> Matsui, 1993 from the Ryukyu Islands seems to be extremelly similar to that of <i>L. hammondi</i> based on the drawing published by Matsui (1993). <i>Laccobius yonanguniensis</i> is most likely a junior synonym of <i>L. hammondi</i> but we were not able to examine the types of the former species. For that reason, we refrain from establishing this synonymy here.</p> <p> <b> <i>Laccobius</i> (<i>Microlaccobius</i>) <i>himalayanus</i></b> Gentili, 1988</p> <p> <b>Material examined.

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
