(Figures 2, 4, 5e–f) Uenotrechus liboensis nandanensis Deuve et Tian, 2010: 101 (Type locality: Cave Dadongqiao Dong) Material examined. 2 males and 1 female (SCAU), 1 male (MNHN), the type series, labeled “ Cave Dadongqiao Dong, Encun, Nandan County, Guangxi, XII-27-2008, leg. Zhihong Xue, Wei Lin and Lei Gao ”. Diagnosis. Similar to U. liboensis Deuve et Tian, 1999, but head nearly parallel-sided, appendages slightly stouter, hind pronotal angles sharply rectangular, base of pronotum almost straight; furthermore, male aedeagus stouter, with a longer and markedly reflexed apical notch in lateral view, and distinctly constricted at subapex in dorsal view (Figs. 5e–f), versus slender aedeagus, with a rather short and less reflexed apical notch, and fairly broad at subapex in U. liboensis (Figs. 5a–d). Habitus as in Fig. 4. Distribution. China (Guangxi) (Fig. 2). Known only from Cave Dadongqiao Dong, Nandan County.Published as part of Wei, Guofu, Chen, Jujian & Tian, Mingyi, 2017, A review of the aphaenopsian ground beetle genus Uenotrechus Deuve et Tian, 1999 (Coleoptera: Carabidae: Trechinae), pp. 361-373 in Zootaxa 4282 (2) on pages 364-365, DOI: 10.11646/zootaxa.4282.2.9, http://zenodo.org/record/81874

Investigation of code reconfigurable fibre Bragg gratings for Optical Code Division Multiple Access (OCDMA) and Optical Packet Switching (OPS) Networks
No full textThis thesis documents my work in the telecommunication system laboratory at the Optoelectronics Research Centre, towards the implementation of code reconfigurable OCDMA and all-optical packet switching nodes based on fibre Bragg grating (FBG) technology. My research work involves characterizing the performance of various gratings, specifically high reflectivity, short chip duration, long code sequences, multiple phase level and tunable superstructured fiber Bragg gratings (SSFBGs), by using the recently proposed Frequency-Resolved Optical Gating technique based on Electro-Absorption Modulator (EAM-FROG). This technology can obtain the complex code profile along the grating, making it a powerful method to understand the thermally-induced code-reconfigurable grating. Efforts have been made to improve the grating design to achieve better system performance. Three different types of FBGs optical encoder/decoder, e.g. conventional discrete phaseshift SSFBGs, code-reconfigurable gratings, and novel continuous phase-shift SSFBGs, have been investigated comparatively, as well as their performance in various optical coding/decoding systems. This thesis also discusses the possibility of reducing multiple access interference (MAI) using a Two-Photon Absorption (TPA) process. The advanced grating devices enable the improvement of system performance. A dynamically reconfigurable optical packet processing system and a 16-channel reconfigurable OCDMA/DWDM system with 50GHz DWDM intervals has been demonstrated.These results highlight the feasibility of FBG-based optical coding/decoding techniques, with improved system flexibility and sustainability
Eutrichodesmus spinatus Liu & Tian, 2013, sp. n.
No full textEutrichodesmus spinatus sp. n. Figs 6–8 Material: Holotype male (SCAU), China, Hunan Prov., Sidu Town, Sidu Caves, 28.06. 2011. leg. Tian Mingyi, Gao Qi & Sun Feifei (CHIhn 11 -LWX01). Paratypes: 1 male, 2 females (SCAU), same locality, together with holotype. Name: To emphasize the gonopod telopodite carrying a conspicuous, spinigerous, lateral, distofemoral process (dp). Diagnosis: Differs from congeners by the volvation being apparently imperfect because the paraterga are mostly only slightly declivous; the metaterga behind collum with three transverse isostictic rows of large rounded tubercles; the gonopod telopodite with a conspicuous, spinigerous, lateral, distofemoral process (dp) at about midway while the acropodite is simple and very strongly curved. Description: All characters as in E. digitatus sp. n., except as follows. Length of adults of both sexes ca 6.5 -8.0 mm, width 1.2-1.5 mm. Holotype ca 7.5 mm long and 1.5 mm wide. Coloration uniformly pallid (Fig. 6 A). Conglobation pattern typical of “ Doratodesmidae ”, but volvation apparently imperfect because of paraterga mostly being only slightly declivous, leaving small lacunae laterally even when body is maximally enrolled. Antennae (Fig. 3 C) rather short and stout. Collum with five regular transverse rows of large round tubercles (Fig. 6 B). Limbus not microcrenulate (Fig. 6 D). Dorsum behind collum with three transverse isostictic rows of large rounded tubercles, each row with about 10 tubercles, but dorsum only with few setae. Paratergal surface coarse, without tubercles; paraterga slightly declivous, broad, 3 - or 4 -lobate laterally, nearly parallel to level of venter, caudolaterally at base with one distinct impression, thus somewhat interrupting the contour of a convex dorsum (Figs 6 A-B). Paraterga 2 strongly enlarged, with three lobulations anterolaterally. Paraterga 3 and 4 slightly shorter than others, each with three lobulations anterolaterally. Pleurosternal ridges wanting. Sterna between ♂ coxae 6, 7 and 9 much wider. Legs rather long and relatively slender, reaching tips of paraterga; femora and tarsi longest, subequal in length; some setae with microdenticulations (Fig. 6 E). Gonopods (Figs 3 F-H) very simple. Coxae subquadrate, large, microtuberculate and abundantly setose ventrolaterally. Telopodite longer than coxite, slender throughout, setose in its basal half, with a conspicuous, spinigerous, lateral, distofemoral process (dp) at about midway. Acropodite very strongly curved ventrad; seminal groove terminating subapically with a hairpad. Remarks: This is a typical “doratodesmid”, possibly a troglobite.Published as part of Liu, Weixin & Tian, Mingyi, 2013, Four new cavernicolous species of the millipede genus Eutrichodesmus Silvestri, 1910 from southern China (Diplopoda: Polydesmida: Haplodesmidae), pp. 281-291 in Zootaxa 3734 (2) on pages 285-287, DOI: 10.11646/zootaxa.3734.2.11, http://zenodo.org/record/21850

Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
