Riazocoris niger Ahmad & Afzal 1977
No full textRiazocoris niger Ahmad & Afzal, 1977 Riazocoris nigra Ahmad & Afzal, 1977 in Ahmad et al. (1977: 161). Lectotype (designated by Ahmad & Afzal 1979: 7, as holotype): ♂, Pakistan: Sind: Thatta (NHMK). Riazocoris nigra: Ahmad & Afzal, 1979: 4–7 (redescription, illustrations, host plant); Ahmad (1980): 137 (list); Ahmad (1981): 52, 105, fig. 8 (checklist, host plant, illustration). Nomenclature. The name Riazocoris nigra with explicitly given authorship of Ahmad and Afzal first appeared in morphological paper devoted to description of its internal organs by Ahmad et al. (1977), which is sufficient to make it available from that publication. The intended original description appeared later in Ahmad & Afzal (1979: 4). The fact that Riazocoris has been combined with an unavailable generic name in Ahmad et al. (1977) has no effect on its availability (see ICZN 1999: Art. 11.9.3.1). There is no mention of type material in Ahmad et al. (1977). As holotype is defined as ‘the single specimen upon which a new nominal species-group taxon is based in the original publication’ (ICZN 1999: Art. 73.1), the subsequently designated ‘holotype’ by Ahmad & Afzal (1979: 7) must be considered the lectotype according to ICZN (1999: Art. 74.5). As the generic names ending with - coris (a Latinized Greek noun meaning true bug) are masculines, the gender agreement of the species name is corrected as R. niger according to ICZN (1999: Art. 31.2).Published as part of Salini, S. & Kment, Petr, 2021, The genera Agathocles and Surenus (Hemiptera: Heteroptera: Pentatomidae) tribal reassessment, redescription, new synonyms, and description of two new species, pp. 510-559 in Zootaxa 4958 (1) on page 549, DOI: 10.11646/zootaxa.4958.1.31, http://zenodo.org/record/469236

(1977): 161 –164, Figs 1–2 (description of morphology of alimentary and male and female reproductive organs, salivary glands and scent glands). Riazocoris Ahmad & Afzal, 1979: 4–7 (description, illustrations); Ahmad (1980): 125, 137 (list); Ahmad (1981): 52, 105, fig. 8 (checklist, illustration); Ahmad & Kamaluddin (1989): 170, 174, 176, 181–182 (key to genera, diagnosis, phylogenetic relationships). Nomenclature. The generic name Riazocoris Ahmad & Afzal first appeared in the paper by Ahmad et al. (1977) describing the internal organs of Riazocoris niger. In that paper neither the type species of Riazocoris has been designated (ICZN 1999: Art. 13.3) nor it became available as a combined description of new genus and species because none of the taxa was marked as new (ICZN 1999: Art. 13.4). The name Riazocoris was made available by Ahmad & Afzal (1979).Published as part of Salini, S. & Kment, Petr, 2021, The genera Agathocles and Surenus (Hemiptera: Heteroptera: Pentatomidae) tribal reassessment, redescription, new synonyms, and description of two new species, pp. 510-559 in Zootaxa 4958 (1) on pages 547-549, DOI: 10.11646/zootaxa.4958.1.31, http://zenodo.org/record/469236

Lodosocoris Ahmad & Afzal 1986
No full textLodosocoris Ahmad & Afzal, 1986 Lodosocoris Ahmad & Afzal, 1986: 200. Type species by original description: Lodosocoris azhari Ahmad & Afzal, 1986: 200–201, fig. 1–6. References. MEMON Et Al. (2011): 1149–1169 (Lodosocoris, phylogeny, key). Redescription. Dark brown to black bugs mottled with irregular, yellowish markings. Head flat dorsally, not declivous, lateral margins of head concave medially. Mandibular plates straight, length with respect to clypeus variable, each of them gradually narrowing towards apex, not meeting in front of clypeus, lateral margins of mandibular plates with distinct tooth subapically nearly right angle to mandibular apex; apex of clypeus slightly broader than mandibular plates. Antennae with basiflagellum (III) longest. Anterolateral margins of pronotum concave at middle and serrated, humeri slightly elevated and knob-like. Scutellum subtriangular with posterior 1/3rd abruptly narrowed. Connexivum broad and completely exposed. Hemelytra with membrane extending slightly beyond apex of abdomen. Length of labium variable; extending beyond middle to reaching posterior margin of ventrite IV. Mesosternum with narrow, central, longitudinal carina. Peritreme typical of Halyini type (Salini 2019, Fig. 91); peritreme (p) spout-shaped (crescent-shaped) reaching middle of metapleuron with well-developed evaporatorium (Fig.7). Evaporatorium extending to posterior border of mesopleuron. Metathoracic spiracle long, narrow and distinctly visible in ventral view.Abdomen on ventral side with central, longitudinal groove reaching posterior margin of ventrite V. Legs without spines, outer surface of tibiae with central longitudinal groove. Discussion. Ahmad and Afzal (1986) gave more emphasis on the characters such as clypeus longer than mandibular plates and fore tibiae undilated especially for differentiating the genera Lodosocoris as well as Neolodosocoris from members of Dalpada. But we noticed that the specimens examined, for this paper, have either clypeus as long as (Fig. 4) or slightly longer than mandibular plates (Fig. 3). Hence this character is quite variable and cannot be used as reliable diagnostic to distinguish this genus from other members of Dalpada. Length of labium (reaching or slightly extending beyond middle of ventrite IV) and presence of a minute tooth in front of compound eyes (Fig. 4) (sometimes absent) are other characters which are variable, though the latter was not mentioned in the original description. Both L. azhari and L. santhae sp. nov. have broad clypeus at apex of head. Parameral crown broad, with a beak-like projection is characteristic of this genus. Apart from this, the short, stout finger-like process laterally on infoldings of ventral rim is another diagnostic for the genus.Published as part of S, Salini, K, Rabbani M., U, Amala & G, Mahendiran, 2021, First record of the genus Lodosocoris Ahmad & Afzal (Hemiptera: Heteroptera Pentatomidae: Halyini) from India with description of a new species, pp. 53-62 in Zootaxa 5072 (1) on page 54, DOI: 10.11646/zootaxa.5072.1.6, http://zenodo.org/record/572989
Trench width dependant deeply etched surface-defined InP gratings for low-cost high speed DFB/DBR
No full textIn this paper we are reporting a fabrication process for multi-section telecom lasers based on surface defined lateral gratings, which is compatible with low-cost high-throughput nano-imprint lithography. A new grating definition process is developed, which allow a better control of the cross section geometry to obtain higher coupling strength
SUPPLEMENT: Secular trends in risk of stroke according to body mass index and blood pressure, 1976-2017
No full textSupplement for for submitted article.ObjectiveTo test the hypothesis that the associations of body mass index (BMI) and BMI-related riskfactors with risk of stroke have attenuated over time using cohorts recruited from the generalpopulation over 4 decades.MethodsWe undertook prospective studies of 2 cohorts enrolled in 1976 to 1978 (13,567 participantsfrom the Copenhagen City Heart Study) and 2003 to 2015 (107,040 participants from theCopenhagen General Population Study). Each cohort was recruited randomly from the Danishgeneral population 20 to 100 years of age. Participants were followed up from the date ofexamination to date of emigration, death, or stroke event, whichever occurred first. Follow-upended in March 2017. We did not lose track of any individual. BMI and blood pressure weremodeled with splines and in categories. Main outcome was incident stroke, including ischemicstroke, intracerebral hemorrhage, and subarachnoid hemorrhage.ResultsThe crude incidence of stroke declined in extreme categories of BMI and blood pressure from1977 to 2017. The multivariable-adjusted hazard ratios for stroke in participants with BMI ≥30vs 18.5 to 24.9 kg/m2 were 1.4 (95% confidence interval 1.2–1.6) in the 1976–1978 cohort and1.1 (1.0–1.2) in the 2003–2015 cohort (p = 0.008 for 1976–1978 vs 2003–2015). The correspondinghazard ratios (confidence intervals) in participants with blood pressure ≥160/100vs <140/90 mm Hg were 2.1 (1.9–2.3) and 1.5 (1.4–1.7), respectively (p < 0.001). Similarsecular trends were observed for diabetes mellitus but were not obvious for other risk factors.ConclusionThe associations of high BMI and high blood pressure with higher risk of stroke were attenuatedacross 2 Danish cohorts enrolled from 1976 through 2015
Diffusive author(s), cohesive author: Analysis of S/N (1994)
No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)
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
